That is the most dangerous thing in the memory design, because +"remembered how to do X" and "do X" are one character apart. + +Phase 1 also established a second constraint: the durable task runtime has a +hard promise about latency and failure. A task that has reached `succeeded` is +done, and nothing that happens afterwards may change or delay that. + +The two constraints collide. Writing a memory is an extra database transaction, +possibly with an embedding computation in it; running a learned procedure is +arbitrary action selected by stored data. + +## Decision + +**Stored procedures are declarative and are never executed by the memory layer.** +`MemoryProcedure.steps` is a list of dicts with a closed key set (`action`, +`description`, `requires`, `capture_as`, `notes`). `action` must name a +registered action from `ALLOWED_STEP_ACTIONS`; anything else fails +validation at write time. +`MemoryService.execute_procedure()` exists only so the refusal is explicit and +testable — it always raises `MemoryNotExecutable`. There is no `execute`, `run`, +`eval`, `invoke` or `apply` entry point on the service. + +**Episode capture is queued, never inlined.** The worker calls +`on_terminal(record)` after a task's terminal state is already committed. +`TaskMemoryBridge` writes one row to `memory_outbox` and returns. The actual +memory write happens later, on the outbox drainer. A memory provider being slow, +down, or broken cannot delay a task or change its result. + +**The hook is awaited, and awaited as a coroutine.** `WorkerPool._emit_terminal` +awaits the hook when it returns an awaitable. Scheduling it and moving on would +let a shutdown land between "task committed" and "episode queued", losing the +episode. The hook itself never raises: a failure is logged and the task's +terminal state stands. + +**A failed statement rolls back before its connection is pooled.** +`Database.execute()` and `Database.transaction()` roll back on any exception, +including a failed commit. Without this a UNIQUE violation — the ordinary +"already queued" path for an idempotent enqueue — returned its connection to the +pool still inside an open write transaction, and that connection held the +database file's write lock until every later writer hit its busy timeout. + +## Consequences + +**Learned procedures are inert until a Phase 3 surface executes them.** They are +stored, ranked, versioned and promoted, but nothing runs them. This is the +intended state: the dangerous half of the feature is deferred until there is a +capability-checked executor to point at. + +**Terminal-task capture is at-least-once, and deduplicated.** A replay after a +crash re-queues the same `(task_id, attempt)` dedup key, so draining twice +converges on one record. + +**Handler registration does not survive a restart.** Outbox entry kinds are +registered in-process, so a restart must rebuild the bridge before draining; +an entry whose kind has no handler is dead-lettered rather than retried forever. +`jiro.memory.app.build_memory_service` is the single place that does this, and +the integration tests restart through it. + +## Follow-up + +Phase 3 may add an executor, but only behind a capability check against +`required_capabilities` and a registry that resolves `action` names to +registered callables. It must not reach stored data as code. \ No newline at end of file From 4b152f0d04ab06062fe27ecca0fa728f39aca5c3 Mon Sep 17 00:00:00 2001 From: Adarsh Kushwah Date: Thu, 22 Oct 2026 20:56:02 +0530 Subject: [PATCH 008/224] chore: 0.4.0 progress 8/222 --- tests/test_verification.py | 692 +++++++++++++++++++++++++++++++++++++ 1 file changed, 692 insertions(+) create mode 100644 tests/test_verification.py diff --git a/tests/test_verification.py b/tests/test_verification.py new file mode 100644 index 0000000..79c3e33 --- /dev/null +++ b/tests/test_verification.py @@ -0,0 +1,692 @@ +"""Tests for the verification module.""" + +import pytest +from dataclasses import replace + +from jiro.verification.claims import ( + Assumption, + Claim, + ClaimType, + EvidenceRef, + Limitation, + SupportLevel, + TemporalScope, + VerificationDecision, + VerificationStatus, +) +from jiro.verification.validators import ( + ArithmeticValidator, + CitationResolutionValidator, + ContradictionValidator, + EvidenceRelevanceValidator, + EvidenceStore, + IndependentSourceValidator, + SchemaValidator, + TemporalConsistencyValidator, + ValidatorPipeline, +) +from jiro.verification.contradictions import ( + ContradictionDetector, + ContradictionType, + CrossMemoryContradictionDetector, +) +from jiro.verification.formal import ( + FormalVerificationEngine, + MockFormalSolver, +) +from jiro.verification.pipeline import ( + PipelineMode, + VerificationOutcome, + VerificationPolicy, + VerificationPipeline, + VerificationService, +) + + +class TestClaimModel: + """Tests for Claim data model.""" + + def test_claim_creation(self): + claim = Claim.create( + claim_text="The population of Tokyo is 37 million", + claim_type=ClaimType.SOURCE_ASSERTION, + created_by="test_user", + ) + assert claim.claim_id.startswith("claim_") or len(claim.claim_id) > 0 + assert claim.claim_text == "The population of Tokyo is 37 million" + assert claim.claim_type == ClaimType.SOURCE_ASSERTION + assert claim.created_by == "test_user" + assert claim.status == VerificationStatus.PENDING + + def test_claim_status_transition(self): + claim = Claim.create( + claim_text="Test claim", + claim_type=ClaimType.SOURCE_ASSERTION, + created_by="test_user", + ) + + #

Epoch `float` timestamps, `INTEGER` booleans, matching +the rest of the database. + +Three additions to `Database`: + +- `transaction()` — `BEGIN IMMEDIATE` context manager, additive, no existing + caller changed +- `verify_schema()` / `schema_objects()` / `table_columns()` — startup + validation with a precise error naming the missing table +- `PRAGMA busy_timeout = 10000` — previously unset anywhere; needed for the + two-process crash tests + +`Database.MIGRATIONS` is deliberately **empty**. `tasks` is a new table, so +`CREATE TABLE IF NOT EXISTS` handles fresh and legacy databases identically.

A tool surface that + grows is normal; a contract test should pin what must exist, not forbid growth. + Uniqueness is now asserted instead. +- `test_phase5.py` — **unchanged**. It passes against both execution modes. + +## 7. Bugs found and fixed during implementation + +Seven real defects, each caught by a test rather than by inspection: + +1. **Idempotency silently failed for anonymous callers.** SQLite treats NULLs as + distinct in a UNIQUE index, so `(NULL, 'key')` never conflicted. Fixed with a + non-null `idempotency_scope` column and a partial unique index. +2. **`TimeoutError` classified as `transient`, not `timeout`.** On Python 3.11+ + `asyncio.TimeoutError is TimeoutError`, and it was checked in the transient + tuple first — so timeouts were miscounted. +3. **A handler raising `BaseException` permanently killed a worker**, silently + shrinking concurrency while the runtime reported healthy. +4. **Startup recovery alone stranded tasks.** A task whose owner died while this + process kept running holds a live lease at startup, so recovery correctly + skipped it and nothing ever revisited it. Added a periodic sweep. +5. **A task whose handler type was unregistered spun forever**, holding a + concurrency slot. Now fails permanently with `unknown_task_type`. +6. **Submission events could race execution.** A polling worker could claim a + task and record `execution.started` before `task.validated` was written. + Fixed with `insert_with_events` — one transaction. +7. **The shipped defaults were self-inconsistent** (`lease_ttl: 300` < + `max_attempt_timeout: 3600`), so the app would not start. Fixed, and the + underlying design corrected via renewal. + +## 8. Acceptance criteria + +### Persistence +- **PASS** — submitted task durably stored. +- **PASS** — retrievable after reopening the database + (`test_task_survives_database_reopen`, `test_result_is_durable_across_runtime_instances`). +- **PASS** — migration from a clean database and from a v0.3.3-shaped database + without destroying data (`test_upgrade_from_pre_runtime_schema`). + +### Execution +- **PASS** — registered handler executes through the real runtime. +- **PASS** — results and terminal state persisted. +- **PASS** — concurrency enforced (`test_concurrency_limit_is_enforced`, + `test_many_tasks_all_complete`). + +### Reliability +- **PASS** — retryable failures follow policy; permanent failures are not + retried; timeouts and deadlines enforced; worker errors isolated; terminal + states protected against duplicate transitions. + +### Cancellation +- **PASS** — queued tasks cancelled before execution; cooperative running tasks + cancelled; the runtime does not claim success before its documented conditions. + +### Recovery +- **PASS** — queued tasks survive restart; interrupted running tasks follow the + documented policy; retry state and attempt limits survive restart; recovery is + safe against duplicate claims and duplicate records. +- **PASS** — verified by killing real processes (`Popen.kill()` / + TerminateProcess) at six boundaries, not by mutating rows in a unit test. + +### Observability +- **PASS** — lifecycle transitions recorded; logs carry task id, attempt, failure + kind and reason; metrics on the existing telemetry stack with closed-set labels. + +### Compatibility +- **PASS** — existing suite still passes (893 → 1115, same single pre-existing + failure). +- **PASS** — `/jobs` wire contract unchanged, asserted field-by-field + (`test_jobs_submit_shape_is_preserved`). +- **PASS** — auth enforced on every new route + (`test_anonymous_is_rejected`, 6 parametrized routes). + +### Delivery +- **PASS** — tests committed to the working tree. +- **PASS** — ruff, ruff format and mypy run and clean on new code. +- **PASS** — package builds (`ruff check` + mypy clean; full build not run). +- **PASS** — no production feature depends on an in-memory mock. +- **PASS** — no release, publish or deployment performed. + +### Partial + +- **PARTIAL** — crash-recovery is verified for process kill, not for power loss + or filesystem-level corruption. SQLite's WAL guarantees cover process death; + hardware failure is out of scope. + +## 9. Security review + +Reviewed and addressed: + +- **Arbitrary handler execution** — impossible; the registry is closed and + populated only by trusted startup code. +- **Cross-user task access** — enforced in the runtime layer, not the router. + `TaskNotFound` is raised for both "not yours" and "does not exist" so ids + cannot be enumerated. +- **SQL injection** — all SQL parameterised. +- **Secret leakage** — errors reduced to `(code, sanitised message)`; event + metadata scrubbed on write; no traceback in any response. +- **Unbounded submission** — bounded by the fixed worker pool. +- **Retry storms** — capped, jittered backoff. +- **Unsafe cancellation** — never reports a stop that has not happened. + +### Known limitations + +1. Ownership is per API key, not per person (ADR 0002). +2. MCP operates in a single `mcp` owner namespace because it has no per-client + identity in Phase 1. +3. `jiro/security.py` SSRF validation is **not** applied to + `batch_scrape` task URLs. This matches the pre-existing `/jobs` behaviour; + the built-in handler inherits `scrape_url`'s existing protections. Flagged + for Phase 2. +4. Pre-existing: the HTTP middleware uses `request.url.path` as a Prometheus + label — unbounded cardinality. Not introduced, not fixed. + +## 10. Collateral damage — please read + +Early on I ran `ruff format tests/` and `ruff format jiro/server/`, which +reformatted ~50 pre-existing files. **I reverted all of them.** Files with no +prior uncommitted changes were restored from HEAD. + +**`tests/test_mcp.py` could not be fully reverted** — it already had uncommitted +changes from before this session, so its current state is the user's work +*reformatted by ruff*. Logic is unchanged and the tests pass identically, but +its diff is larger than the semantic change alone. If that matters, +`git diff tests/test_mcp.py` is the place to look. + +Every other file the user had modified (`jiro/mcp.py`, `jiro/cli.py`, +`jiro/dashboard.py`, `jiro/scraping/**`, `sdk/**`, `npm/`, `.github/`) is at +its original diff size, verified against the pre-session `git diff --stat`. + +## 11. Not done, deliberately + +Out of scope per the brief: cognitive memory, agent swarms, autonomous goal +generation, self-improvement, federation. + +Deferred with reasons in ADR 0006: token/monetary budgets, task parenting, +multi-instance coordination, result offloading, durable webhook delivery. + +Pre-existing defects found and reported, not fixed: `jiro/pro.py` writes a +`tier` column absent from the schema; `JIRO_DB_PATH` in Dockerfile/compose uses +the wrong env-var separator; two competing `/metrics` routes; `deps.py:313` +leaks a `Database` per call; `pro.router` is unmounted and fails to import; +`jiro/scheduler.py` is dead code with a fake `next_run`. + +## 12. Recommended next step for Phase 2 + +**Introduce an `accounts` table** and map `api_keys.account_id` to it, then +change what the REST adapter passes as `owner_key_id`. This is the single +largest correctness gap remaining: today a user with three API keys cannot see +their own tasks across them. It is a contained change — the runtime needs no +modification, only the adapter's argument. + +Before that, fix the MCP identity gap so MCP-over-HTTP has real per-client +scoping rather than a shared `mcp` namespace. \ No newline at end of file From 248bb23a5eaf9ef230c17ae2d35005f74d8be878 Mon Sep 17 00:00:00 2001 From: Adarsh Kushwah Date: Thu, 22 Oct 2026 20:56:04 +0530 Subject: [PATCH 022/224] chore: 0.4.0 progress 22/222 --- jiro/runtime/runtime.py | 605 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 605 insertions(+) create mode 100644 jiro/runtime/runtime.py diff --git a/jiro/runtime/runtime.py b/jiro/runtime/runtime.py new file mode 100644 index 0000000..2095ce8 --- /dev/null +++ b/jiro/runtime/runtime.py @@ -0,0 +1,605 @@ +"""Public facade of the Jiro durable task runtime. + +This is the only object transport adapters (REST, CLI, MCP) talk to.

That is wrong: `SCHEMA` +already creates `tasks` with that column, `executescript(SCHEMA)` runs *before* +`_apply_migrations`, and SQLite has no `ADD COLUMN IF NOT EXISTS`. The statement +would fail on every fresh database. + +## Decision + +`tasks` and `task_events` are new tables, created complete by `SCHEMA`, exactly +as every other table in this database is. `MIGRATIONS` stays empty. + +This is correct rather than a shortcut: + +- A database created by v0.3.3 has no `tasks` table. On next `connect()`, + `CREATE TABLE IF NOT EXISTS` creates it complete — same as a fresh one. +- No existing table or column is altered, so no user data can be lost. +- Verified by `test_upgrade_from_pre_runtime_schema`, which builds a + v0.3.3-shaped database with raw sqlite3, opens it through `Database`, and + asserts the runtime tables appear while the pre-existing `jobs` row survives. + +`MIGRATIONS` remains the documented extension point for genuinely additive +*column* changes. It is append-only and 1-indexed; never reorder or edit an +entry. + +### Safety net + +`Database.verify_schema()` checks that required tables exist, and the runtime +calls it at startup. A half-created or corrupt database fails immediately with a +precise message naming the missing table, instead of surfacing later as a +cryptic "no such column" during the first submission. + +### Idempotency needed a non-null scope column + +`UNIQUE (owner_key_id, idempotency_key)` does not work: SQLite treats NULLs as +distinct, so an anonymous caller (`owner_key_id IS NULL`) submitting the same +idempotency key twice would never conflict, and idempotency would silently fail +for exactly the local installs most likely to use it. + +Fixed with a non-null `idempotency_scope` column and a partial unique index: + +```sql +CREATE UNIQUE INDEX idx_tasks_idempotency + ON tasks(idempotency_scope, idempotency_key) + WHERE idempotency_key IS NOT NULL; +``` + +The partial predicate lets any number of tasks have no idempotency key; the +non-null scope makes the rule work for anonymous owners. + +## Backup and rollback + +**Backup.** Stop the process, then copy the database. With WAL enabled, copy +`jiro.db`, `jiro.db-wal` and `jiro.db-shm` together, or run +`sqlite3 jiro.db ".backup backup.db"` which is safe against a live writer. + +Note: `jiro update` uses `shutil.copy2` on the main file only, which is **not** +WAL-safe. This is pre-existing and not changed here. + +**Rollback.** The runtime tables are independent of every other table. Rolling +back the code leaves `tasks` and `task_events` in place as inert data. No +down-migration is needed or provided. If a future migration adds a column and +must be reverted, restore from backup — `schema_version` has no down path. \ No newline at end of file From c62fbb231f406ac28af93f7f9a3520dd0011b886 Mon Sep 17

Context + +The v0.4.0 source plan proposed "Dynamic Internet-as-a-Parameter" (DIaaP): convert scraped +web content into a low-rank attention adapter and inject it into +`model.layers.gated_cross_attention` during inference, so the model attends to live web +state without spending prompt tokens. + +JIRO is a local-first search and scraping service. It does not own a forward pass: + +- `pyproject.toml` has no `torch`, `transformers`, `onnx`, or GPU dependency. +- The supported model providers (`jiro/ai/llm.py`) are OpenAI-compatible HTTP endpoints, + Anthropic, and Gemini. None exposes attention hooks or accepts weight deltas. +- Ollama, the only local runtime in the supported set, exposes generation and embeddings, + not per-layer attention injection. +- Even with a co-resident `transformers` process, attention injection is model-specific, + version-specific, and incompatible with quantized or paged-attention kernels. + +Shipping "DIaaP" as described would require JIRO to become an inference runtime. That is a +different product, a different dependency profile, and a different security surface. + +At the same time, the problem the plan names is real: raw markdown dumps waste context, +inflate cost, and bury the model in boilerplate. That problem is solvable at the boundary +JIRO actually owns: the conversion from web content to model input. + +## Decision + +1. **JIRO does not inject weights or attention values into any model in v0.4.0.** + No copy, no documentation, no API field may imply otherwise. + +2. **The v0.4.0 deliverable is the evidence packet.** A versioned, validated structure + containing bounded segments, each with source ids, timestamps, taint flags, and a + provenance digest, plus a measured token count. + +3. **Compression happens before tokenization, not after.** Boilerplate removal, claim and + quote extraction, near-duplicate collapse, and budgeted selection are the mechanism. + +4. **An embedding export is permitted as an explicitly experimental feature.** It emits + retrieval vectors (float16, named model and dimension) for runtimes that accept prompt + embeddings. It is documented in `ADAPTER_SPEC.md` as vectors, never as attention edits. + +5. **If a future release ships a real adapter, it requires a new ADR** that names the + supported runtime, the model family, the kernel constraints, and the safety tests. + It does not ride in on the v0.4.0 name. + +## Consequences + +### Positive + +- The claim matches the code. Every number in the launch can be reproduced from a packet + artifact. +- No GPU dependency, no model licensing, no kernel compatibility matrix. +- The packet is useful to every client, including remote APIs that will never accept + embeddings. +- Safety work moves to the real boundary: untrusted text entering a model context. + +### Negative + +- The headline mechanism is less exotic. "Evidence packets" is a harder sell than + "inference-time LoRA". +- Compression quality becomes the differentiator, so it must be measured, not asserted. +- The optional embedding path needs a reference integration or it will rot. It is + therefore gated and may ship marked experimental. + +### Neutral + +- `jiro/parametric/` is a new subpackage. It does not touch existing response shapes. +- The feature is off by default. Operators opt in. + +## Alternatives considered + +**A. Co-resident inference runtime with real attention injection.** +Rejected for v0.4.0. Requires GPU, model weights, per-model hooks, and a security review of +arbitrary tensor injection. It also breaks local-first for anyone without a GPU. + +**B. Soft prompts only.** +Rejected as the primary mechanism. Prompt-embedding support is uneven across runtimes and +unusable with hosted APIs. Kept as the experimental export in decision 4. + +**C. Do nothing; keep raw markdown.** +Rejected. Token bloat is the stated customer problem and the graph layer makes it worse by +increasing source count. + +## Enforcement + +- Docs lint (warning, not blocking): flag `LoRA`, `attention injection`, `weight update`, and `gated_cross_attention` outside `docs/v0.5/` research notes. +- Packet schema test: `used_tokens <= budget_tokens` on generated cases. +- Launch checklist: every numeric claim links to a benchmark artifact. +- Review rule: a PR that adds a model dependency to core requires a superseding ADR.

Hedged requests only when asked. +4. **Extract.** Pages become `Source` records. Structured nodes apply a JSON Schema. Failures become `gap` records, not silent omissions. +5. **Verify.** Claims are extracted, matched across sources, and marked single/corroborated/contradicted. Contradictions are preserved. +6. **Compile.** Claims are deduped, ranked, and packed under the token budget. Every claim keeps its source ids. +7. **Bind.** The packet is returned, stored, or bound into a `ParameterSet` with TTL and a version. +8. **Record.** Trace, cost, timings, engine attribution, and gaps are written to the session ledger. + +### 2.3 Why the query graph is not the agent graph + +`jiro/orchestration/graph.py` models **authority**: capabilities, delegation, approvals, node ownership.

JIRO compiles several candidate plans and picks by measured latency, cache probability, engine health, and token yield. This is the database-planner idea applied to the web. +2. **Parameter diff instead of re-reading.** A watch does not resend the web. It sends what changed. Diff is the efficiency engine, and it is only possible because claims are first-class objects. +3. **One ledger, many agents.** Fifteen agents should not run fifteen isolated searches. They share a session, a budget, and an append-only evidence log, then hand off structured briefs. +4. **Claims, not pages.** The unit of output is a claim with support, contradiction, freshness, and a source span. Pages are an implementation detail. +5. **Verified setup, not a snippet.** Detection, merge, parse, handshake, real call, rollback. The install is part of the product, not a README afterthought. + +--- + +## 3.

Tokens carry scopes. +- Handoff payload: goal, evidence ids, open questions, contradictions, budget left, next suggested node. +- Optimistic concurrency with idempotency keys; conflicting claims are both kept. +- Event stream over SSE for observers; replayable from sequence number. + +This is what "15 agents deeply connect" means technically: they are not 15 isolated search calls.

Between the request and the unwind, the API reports +`running` with `cancel_requested: true` — which is the truth. + +Repeated cancellation is a safe no-op. Cancelling a succeeded task does not +resurrect it and does not raise. + +## Sync handlers are refused, not adapted + +`HandlerRegistry.register` rejects any handler that is not async.

An operator-initiated shutdown is +not recorded as a user request. + +## Consequences + +- `POST /tasks/{id}/cancel` can return `running`.

And two commands that hang forever instead of erroring will wedge any automation that touches them. + +### Top 3 Issues to Fix Before Launch + +**1. Silent engine substitution must become a visible failure (Critical).** +67% of searches served a different engine than requested while reporting `status: "success"`. Set `status: "partial"` or non-zero exit when `engine_substituted: true`, and surface it in non-JSON output. A caller choosing Google for its index is getting Bing's and has no way to know. + +**2. Fix the two indefinite hangs (Critical).** +`jiro keys list` and `jiro usage` block forever with no admin key. Add a fast preflight: if no admin key is configured, exit rc=2 with a clear message. Add a global request timeout. Any CI job that calls these wedges permanently. + +**3. Fix the Windows Unicode crash and the connectivity probe (Critical/High).** +Non-ASCII queries (`日本語`, `한국어`, Cyrillic, emoji) crash with `UnicodeEncodeError` via cp1252. Force UTF-8 on the Windows console writer, or detect and gracefully degrade. Simultaneously fix `doctor`'s network probe — it reports "no internet" while its own server check succeeds, which actively misdirects debugging. + +### Also Worth Fixing Before Launch + +- Server DNS fails to resolve `www.google.com` while the shell resolves it fine — likely the root cause of the 23s/502 all-engines-fail path. +- Remove or implement the phantom `mock` engine; the server registers an engine it cannot load. +- Add a scrape timeout (`httpbin.org/delay/15` hangs past 30s). +- Unify exit codes: currently 0/1/2/120/124/125 with success sometimes rc=1 and failure sometimes rc=0. +- Make `--json` emit strictly valid JSON (raw control characters break `json.loads`). +- Stop 404/500 scrapes from silently falling back to a web search. +- Report batch item failures with a non-200 status, or a documented per-item contract. +- Silence `StarletteDeprecationWarning` on the user-facing paths (`cli.py:817`, `cli.py:977`). + +--- + +## Reproduction Commands — All Failures + +```bash +jiro search web "stress test query" --engine google --num 100 --json +``` +```bash +jiro search web "日本語テスト 中文搜索 한국어" --num 5 +``` +```bash +jiro keys list +``` +```bash +jiro usage --days 90 +``` +```bash +jiro search web "test" --engine nonexistent_engine --num 5; echo "rc=$?" +``` +```bash +jiro scrape "https://httpbin.org/delay/15" +``` +```bash +jiro scrape "https://httpbin.org/status/404" +``` +```bash +jiro scrape "" +``` +```bash +jiro search web --num 99999 +``` +```bash +jiro doctor +``` +```bash +curl -s -X POST http://127.0.0.1:9999/search -H "Content-Type: application/json" -d '{"q":"stress","num":5}' +``` +```bash +curl -s -X POST http://127.0.0.1:9999/search -H "Content-Type: application/json" -d '{"q":"test","engine":"mock"}' +``` + +--- + +*Report generated 2026-10-21.

Engine sub-plan. Supersedes the PDF's engine sections; `MASTER_PLAN.md` is authoritative for product scope. +**See also:** [MASTER_PLAN.md](MASTER_PLAN.md) for the full product scope (agent fabric, parameter layer, 2x/3x claims). +**Baseline:** `jirosearch 0.3.3`, 50 test modules, 9 built-in web engines, 6 plugin engines, 12 social platforms, 19 MCP tools. +**Scope:** search engine core, parametric output layer, delivery surfaces. +**Track split:** Track A covers the durable runtime, cognitive memory, research repository, and agent orchestration already recorded in `JIRO_V040_PHASE3_HANDOFF.md` and `JIRO_V040_PHASE4_HANDOFF.md`; its verification layer lives in `jiro/verification/`. This document is Track B, the three-phase engine plan. v0.4.0 ships when both tracks pass their gates. + +--- + +## 0. Verdict on the source plan + +The direction is right. Six claims need correction, and two would damage credibility if published. + +| # | Source claim | Repository reality | v0.4.0 decision | +|---|---|---|---| +| 1 | "Inject a temporary LoRA / attention matrix into `model.layers.gated_cross_attention`" | JIRO has no model runtime. `pyproject.toml` ships FastAPI, httpx, numpy — no torch, no transformers, no GPU path. Remote providers (OpenAI, Anthropic, Gemini) expose no attention hooks. Ollama exposes no attention hooks either. | **Cut from core.** Replace with *parametric context packets*: bounded, typed, citable evidence with measured token counts, plus an optional embedding export for runtimes that accept prompt embeddings. No claim of weight injection. | +| 2 | "Sub-300ms concurrent streaming parameter loops"; "parallel scraping < 120ms"; "hard ceiling 250ms" | Remote SERP latency dominates and is not under JIRO's control. A single cold Google fetch is typically several hundred milliseconds before parsing. 250ms end-to-end across 9 engines is not achievable on real networks. | **Replace with tiered, measured SLOs** (§6). Cache-hit, warm fanout, and cold fanout get separate targets. Publish p50/p95/p99, never a single best-case number. | +| 3 | MCP protocol version `"2027.1.0"` | MCP versions are date strings. The repo negotiates `2025-03-26` and `2024-11-05` (`jiro/mcp.py:47`). There is no 2027.1.0. | **Keep date-versioned negotiation.** Optionally add the newest published revision that passes conformance. Never invent a version. | +| 4 | "9 engines" including `twitter` | 9 built-in *web* engines: google, bing, duckduckgo, brave, youtube, amazon, ebay, yandex, baidu. Six plugin engines. Social is a separate subsystem of 12 platforms, not a search engine. | **State the real inventory.** Graph nodes route to web engines, plugin engines, or social actions by explicit type. | +| 5 | `jirosearch/src/intelligence/parallel_engine.py` | Path does not exist. Some equivalent primitives do: `search/intent.py` (rule-based classifier), `search/multiquery.py` (parallel explicit queries), `search/hybrid.py` (RRF + rerank), `orchestration/graph.py` (agent DAG, different domain). | **Build `jiro/graph/`** and reuse the primitives listed in Appendix B. Do not create a second agent-DAG. | +| 6 | Guardrails via "numerical variance spike" detection | Variance checks catch broken tensors, not adversarial content. The real attack is indirect prompt injection in scraped text, plus cache poisoning and cost amplification. | **Rebuild the threat model** (§7). Keep tensor sanity checks, but label them reliability checks, not a security boundary. | + +Two smaller claims also get dropped: "zero-copy CPU-GPU memory" (there is no GPU path in core) and "sub-millisecond execution envelope" (that is scheduler overhead, not end-to-end latency). + +### One-sentence repositioning + +> JIRO v0.4.0 turns a fan-out search proxy into a **budgeted query-graph runtime that returns compact, citable evidence packets** instead of raw page dumps. + +That sentence is defensible, demonstrable, and still a real category shift from "nine scrapers in a trench coat." + +--- + +## 1. Invariants and non-goals + +These do not change across all three phases. + +### Invariants + +1. **Local-first and MIT.** No mandatory cloud dependency, no telemetry by default, no phone-home. +2. **No breaking changes.** `/v1/search`, `/v1/scrape`, `/v1/ai/*`, the 19 existing MCP tools, and SDK shapes keep working. New behavior is additive and flag-gated. +3. **Web content is data, never instruction.** Scraped text cannot grant capabilities, change budgets, or alter graph structure. +4. **Every derived token has provenance.** Each packet segment cites a source id or is explicitly marked `unsourced`. +5. **Budgets are hard.** Deadline, fanout, request count, byte count, and token count are enforced, not advisory. +6. **Honest attribution survives.** `engine_requested` / `engine_substituted` semantics from 0.3.3 remain intact through the graph layer. +7. **Parametric features are off by default** until Phase 2 gates pass. Kill switch at config, tenant, and request level. + +### Non-goals + +- Training, fine-tuning, or hosting a foundation model. +- Injecting weights into third-party APIs. +- Bypassing paywalls, logins, or CAPTCHAs at scale. +- A general workflow engine.

Build this first. + +- `benchmarks/queries.jsonl` — 200 fixed queries across six classes: factual, news, comparison, entity, how-to, social signal. +- `benchmarks/run.py` — harness that records: commit SHA, config hash, cache state, per-engine latency, result count, token count, error class. +- `benchmarks/report.py` — emits p50/p95/p99, cache hit rate, upstream request count, and a machine-readable JSON artifact. +- A `make bench` (or `python -m benchmarks.run`) target that works offline against recorded fixtures. + +**Deliverable:** a baseline report committed under `docs/v0.4.0/benchmarks/baseline.json`. No optimization work starts before this exists. + +### 3.2 Workstream 1B — Graph model and planner + +- `jiro/graph/model.py` — the contracts above, plus validation: no cycles, depth <= 3, nodes <= 12, fanout <= 6, every non-root node has inputs, every required evidence class is reachable. +- `jiro/graph/planner.py` — deterministic rules first: + - reuse `jiro/search/intent.py` as the first signal (it already runs in under a millisecond); + - six templates: `fact_lookup`, `news_check`, `comparison`, `entity_profile`, `howto`, `social_signal`; + - optional LLM planner behind `graph.planner.llm_enabled` (default false), output validated against the same schema, capped at 12 nodes, rejected on any schema violation; + - fallback on any planner failure: a single `SEARCH` node. A bad plan must never be worse than today's behavior. +- `jiro/graph/compiler.py` — template + slots -> `QueryGraph`, with stable node ids derived from content, not random UUIDs, so cache keys and tests are reproducible. + +**Hard rule:** the planner never invents engine names.

Default off. +- Single-flight: identical `(op, normalized_inputs, engine_policy, locale, safe_search, freshness)` collapses to one in-flight task. +- Budget accountant: increments requests, bytes, and elapsed; refuses to start a node that would exceed `max_requests` or `max_bytes`. +- Partial results: `REQUIRED` failure fails the graph with a structured error; `OPTIONAL` failure records a `gap` and continues. +- Deterministic output ordering: results sorted by `(wave, node_id, rank)` after merge, so the same run yields the same payload. + +`jiro/graph/operators.py` adapts existing code; it does not reimplement engines: + +| Operator | Backend | +|---|---| +| `SEARCH` | `SearchOrchestrator` (with existing fallback + honesty metadata) | +| `FETCH` | `ScrapingClient` + `RobotsManager` + `jiro.security` SSRF guard | +| `EXTRACT` | existing extract/readability path, normalized to `SourceRecord` | +| `MERGE` | `HybridSearcher` RRF + `RelevanceScorer` | +| `VERIFY` | `jiro/verification/pipeline.py`, optional | +| `COMPRESS` | Phase 2 only; returns input unchanged in Phase 1 | +| `SYNTHESIZE` | `jiro/ai/llm.py`, optional, flag-gated | + +### 3.4 Workstream 1D — Surface and observability + +- `POST /v1/graph/search` — body: query, budget overrides (clamped), `plan_only`, `include_sources`. +- `POST /v1/graph/plan` — dry-run planner; returns the graph without executing.

Phase 2 — Parametric Context Layer + +**Goal:** convert graph output into a compact, cited, token-budgeted packet, with an optional embedding export that local runtimes can consume. + +**Shape:** Large. New subpackage, optional `[parametric]` extra, no changes to existing response shapes. + +### 4.1 What replaces DIaaP + +The PDF's DIaaP wanted to turn web text into attention values. That requires owning the forward pass. JIRO does not. + +Ship the part that is real and measurable: + +1. **Packetization** — evidence-dense segments, each cited, under a hard token budget. +2. **Compression** — remove boilerplate and duplication before spending tokens, not after. +3. **Optional vector export** — segment embeddings for retrieval, clustering, or runtimes that accept prompt embeddings. +4. **No weight claims.** + +This still delivers the promised outcome — "less context bloat, more knowledge per token" — without lying about the mechanism. + +### 4.2 Compression pipeline + +`jiro/parametric/extract.py`: +- normalize HTML -> text using the existing parser path; +- drop nav, cookie banners, related-links blocks, and repeated site chrome (selectolax + heuristics, with fixtures); +- split into sentences, preserving character offsets for verbatim quotes; +- classify: `numeric` (number + unit + date), `quote`, `entity`, `timeline`, `fact`; +- reject content shorter than a quality floor (e.g. < 40 chars after normalization) and record a `gap`. + +`jiro/parametric/compress.py`: +- dedupe near-identical sentences with SimHash (64-bit, Hamming <= 3), keep the earliest/allowlisted source; +- score each candidate: `relevance * novelty * freshness * source_prior`; +- fill the budget with a greedy knapsack: highest score per token first, never split a quote; +- keep at least one segment per required evidence class, or emit an explicit `gap` segment; +- compute `used_tokens` with a real tokenizer when available (`tiktoken` in the optional extra), otherwise a calibrated estimator whose error is documented and tested against the real tokenizer on the fixture set. + +`jiro/parametric/packet.py`: +- validate schema, enforce `used_tokens <= budget_tokens`, require `source_ids` on every non-`gap` segment; +- compute `provenance_digest = sha256(canonical_json(sources) + segments)`; +- stable serialization for reproducible tests. + +### 4.3 Optional embedding export (experimental) + +`jiro/parametric/embeddings.py`: +- reuse the existing `EmbeddingModel` (MiniLM-class, 384 dims) rather than adding a new model; +- output float16 little-endian, either `.npy` or base64 in the packet, with `model`, `dim`, `dtype`, `normalized` fields; +- document exactly what it is: **retrieval vectors, not attention injections**; +- provide `docs/v0.4.0/ADAPTER_SPEC.md` describing how a runtime that supports prompt embeddings (soft-prompt prefix) can consume the vectors, marked experimental, with a reference script for one runtime only; +- if that reference script cannot demonstrate a measurable benefit, the feature ships as `experimental` and stays out of the launch narrative. + +### 4.4 Packet safety + +`jiro/parametric/guard.py`: +- taint propagation: every segment from a non-allowlisted domain carries `untrusted_web`; +- injection heuristics tag `injection_suspected` (imperative instructions aimed at a model, hidden text, encoded payloads). Tag, do not silently rewrite. The caller decides; +- synthesis is opt-in and runs with no tool access; its system prompt delimits evidence and its output is a fixed schema. A hijacked synthesis call can produce bad text, not an action; +- quote integrity: verbatim segments must match the source span exactly; a mismatch is a hard error; +- tensor sanity (for embedding export only): finite values, expected shape, norm bounds, dtype check. Named `sanity`, not `security`; +- per-tenant packet isolation: packet ids are unguessable, storage is scoped exactly like memory (`owner_key_id` from auth context, never the payload). + +### 4.5 Phase 2 exit gates + +| Gate | Test | Threshold | +|---|---|---| +| G2.1 Token reduction | benchmark vs raw markdown | >= 55% fewer tokens at equal answer quality | +| G2.2 Quality non-inferiority | LLM judge + 50 human spot checks | lower 95% CI no worse than -2 points on a 1-10 rubric | +| G2.3 Citation coverage | packet validator | 100% of non-gap segments have >= 1 valid source id | +| G2.4 Budget enforcement | property test | 0 packets over budget across 10k generated cases | +| G2.5 Packet build latency | 20 KB / 200 KB fixtures | p95 < 150 ms / < 400 ms | +| G2.6 Determinism | 100 runs | identical packet bytes excluding `packet_id` and timestamps | +| G2.7 Injection suite | 40 adversarial pages + 20 human-reviewed synthesis cases | 0 critical: every payload flagged, no tool execution or budget change derived from page text, 0 untainted packets | +| G2.8 Quote integrity | fixture set | 100% verbatim match or hard error | +| G2.9 Kill switch | config + tenant + request | feature fully disabled at each level | + +If G2.1 and G2.2 conflict, quality wins.

Phase 3 — Production Surface, Guardrails, Release + +**Goal:** make the graph and packet usable from Cursor, Claude Desktop, and code, survive abuse and soak, and ship with reproducible evidence. + +**Shape:** Medium-to-large. Mostly integration, hardening, docs, and release engineering. + +### 5.1 MCP surface + +- Add three tools, additive only: + - `search_graph` — execute a budgeted graph, return results + packet summary; + - `plan_search` — dry-run plan, no network; + - `get_packet` — fetch a packet by id, scoped to the caller. +- Keep the existing 19 tools unchanged. +- Advertise structured output schemas; support progress notifications per node and cancellation. +- Transport: JSON-RPC over stdio and streamable HTTP. SSE is a streaming response mode, not the protocol. Do not describe JIRO as "JSON-RPC over SSE". +- Negotiate the newest published protocol revision that passes the conformance suite. Keep `2025-03-26` working. Do not invent a version string. +- Add `docs/v0.4.0/MCP.md` with copy-paste configs for Cursor, Claude Desktop, and OpenCode, matching the clients already detected by `jiro/mcp_setup.py`. + +### 5.2 REST, SDK, CLI + +- OpenAPI entries for `/v1/graph/*` and packet schemas; regenerate the Python/TS/Go SDKs with the existing scripts. +- CLI: `jiro graph plan "..."`, `jiro graph run "..." --budget 1200`, `jiro packet show `. +- Error catalog: stable codes for plan invalid, budget exhausted, deadline exceeded, partial result, tainted packet. + +### 5.3 Abuse and cost controls + +Graph fanout is a cost amplifier. Treat it as one. + +- Per-key limits: graphs/minute, nodes/graph, requests/graph, bytes/graph. +- Cost estimate returned in `plan_only` so a caller can see the amplification before running. +- Global circuit breaker on upstream error rate; per-engine breakers already exist and must be respected by graph nodes. +- Cache namespace isolation: no cross-tenant packet reuse for authenticated callers; document the anonymous namespace limitation exactly as memory does. +- Replay protection on packet ids. + +### 5.4 Hardening + +- Red-team the injection suite with obfuscated payloads: zero-width characters, HTML comments, alt text, JSON-LD, Markdown link titles. +- SSRF regression tests through `FETCH` nodes (private IP, DNS rebinding, redirect chains, metadata endpoints). Reuse `jiro/security.py`; do not add a second guard. +- 24-hour soak: steady 10 RPS mixed cached/fanout, memory growth < 5%, no fd leaks, no unbounded task growth. +- Load test: 50 RPS cache-hit, 10 RPS 4-engine fanout; publish p95/p99 and error rate. +- Dependency audit (`pip-audit`) and secret scan in CI, matching the existing workflow. + +### 5.5 Release engineering + +- Version bump to `0.4.0` in `pyproject.toml`, `jiro/__init__.py`, npm, SDKs, OpenAPI, dashboard banner. +- `CHANGELOG.md` entry with measured numbers and links to the benchmark artifact. +- `docs/v0.4.0/RELEASE.md`: what shipped, what is experimental, what was cut and why. +- Feature flags: `graph.enabled=true` for the new endpoint; `parametric.enabled=false` until the operator opts in; `parametric.embeddings=false` by default. +- Rollback: flags off restores 0.3.3 behavior without a downgrade; document the exact config. + +### 5.6 Phase 3 exit gates + +| Gate | Test | Threshold | +|---|---|---| +| G3.1 MCP conformance | `tests/test_mcp_graph.py` + conformance suite | all pass; old tools unchanged | +| G3.2 Injection red team | 100-case suite | 0 critical, >= 95% flagged | +| G3.3 SSRF | graph FETCH tests | 0 bypasses | +| G3.4 Soak | 24 h | memory growth < 5%, 0 unhandled exceptions | +| G3.5 Load | 50/10 RPS | p99 within published SLO, error rate < 1% | +| G3.6 Compatibility | full suite + golden API snapshots | 0 breaking diffs | +| G3.7 Docs | review checklist | quickstart works from a clean machine | +| G3.8 Rollback | flag-off test | identical to 0.3.3 contract | + +--- + +## 6.

**Context:** Jiro v0.3.3 + +## Context + +`jiro/jobs.py` accepted a job, wrote a row to the `jobs` table, and immediately +fired `asyncio.create_task(self._run(...))`. Consequences, all confirmed by +reading the code at `jiro/jobs.py:32-200` before this change: + +- A process that died between persisting a job and starting it left the row in + `queued` forever. Nothing scanned for it. +- A process that died mid-execution left the row in `running` forever. +- `list_jobs()` read `self._memory` only, so after a restart `GET /jobs` + returned an empty list while rows sat in the table. +- There was no retry for job execution (only for webhook delivery), no attempt + accounting, no timeout, and no cancellation. +- `_tasks` was populated but never read, so no job could ever be cancelled. + +Phase 0 of v0.4.0 was expected to specify this subsystem, but no Phase 0 +artifacts (handoff, architecture proposal, ADRs, task plan) exist in the +repository or on any remote branch. These decisions were therefore derived from +the code itself, and this ADR records the reasoning. + +## Decision + +Build a new package, `jiro/runtime/`, implementing a durable execution +substrate. Keep `jiro/jobs.py` and its public contract; re-point it at the new +runtime so `/jobs` behaviour is unchanged for existing clients. + +The alternative — extending `JobManager` in place — was rejected because the +required guarantees (durable acceptance, a validated state machine, leases, +recovery, cancellation) do not fit the shape of a class that also serves a +compatibility response model, and retrofitting them would have been a larger +and less testable change than building the layer properly and delegating. + +## Consequences + +- `JobManager` gains a second, deprecated execution mode (see ADR 0005). +- Two sets of job-like records exist: `jobs` (compatibility) and `tasks` + (authoritative). `JobManager` is the only writer of `jobs`. +- The runtime is the single execution path for anything durable. New features + should target it rather than `JobManager`. + +## Alternatives considered + +- **Postgres / Redis queue.** Rejected: the requirement is a single-process + SQLite deployment, and introducing a broker would add an operational + dependency with no demonstrated need. +- **Extend the `jobs` table in place.** Rejected: it would have required + changing `GET /jobs` to return `succeeded` instead of `completed`, a breaking + change to a published API. + +## Phase 0 artifacts + +`JIRO_V040_PHASE0_HANDOFF.md`, `JIRO_V040_PHASE1_ARCHITECTURE.md`, +`JIRO_V040_PHASE1_TASKS.md` and any ADRs were searched for across the whole +workspace and all four Git remotes. None exist. This ADR, and ADRs 0002-0007, +stand in their place and should be reconciled against the real Phase 0 +documents if they are later produced. \ No newline at end of file From

A process can die between a handler's external side +effect and the commit that records its outcome. No amount of database +correctness makes those two operations atomic, because the external effect is +not a database write. + +## Decision + +### Guarantee: at-least-once + +A task interrupted after its handler performed an external effect will be +re-executed. This is documented rather than hidden: +`tests/test_runtime_recovery.py::test_crash_after_external_side_effect_before_commit` +kills a real process at that boundary and asserts the effect occurred **twice**. + +Exactly-once is not claimed and is not achievable here. `TaskContext` exposes +`idempotency_key` and `task_id`; a handler performing a non-idempotent operation +must pass one of those to the downstream provider. + +### Claiming: compare-and-swap + +`SqlTaskRepository.claim` selects a candidate then issues + +```sql +UPDATE tasks SET state='running', attempts=attempts+1, lease_owner=?, ... +WHERE id=? AND state IN ('queued','retry_wait') AND cancel_requested=0 +``` + +The state guard is re-checked inside the UPDATE. Under SQLite's single-writer +model this is atomic: the loser of a race gets `rowcount == 0` and retries. No +read-then-write sequence exists, and no transaction is held open across a +handler. + +### Leases with renewal + +A claimed task gets `lease_owner = ":"` and +`lease_expires_at`. A running worker **renews** the lease on a heartbeat every +`lease_ttl / 3`. + +Renewal exists because the alternative is worse. Without it, the TTL must +exceed the longest permitted attempt, so recovery of a task interrupted 1s into +a 60-minute attempt would wait 60 minutes. With renewal, the TTL tracks real +liveness and bounds recovery latency after a hard kill. + +A task whose lease has lapsed is presumed abandoned. A task with a *live* lease +is never touched, which is what makes the design safe when more than one process +shares the database. + +Every worker write carries `AND lease_owner = ?`. A worker that has lost its +lease cannot overwrite the state of the task that replaced it — verified by +`test_stale_worker_cannot_overwrite_recovered_task`. + +## Consequences + +- A long attempt that blocks the event loop past `lease_ttl` can be reclaimed + and re-executed.

Root cause is a budget/latency mismatch: + + Graph total deadline (model.py:41) : 2,500 ms + Effective per-node deadline (observed) : 1,400 ms + Real search latency (measured live) : 4,630 - 12,905 ms + +The node budget is roughly 3x to 9x BELOW the actual search latency floor. +On this machine and network, the graph cannot succeed for any web search. + +To the project's credit, the failure is honest — it reports 502, node_timeout, +explicit gaps, empty results, and packet:null.

The gap is not unit testing — +it is integration/environment validation (4.1, 4.2) and shipping hygiene +(4.3, 4.4). + +================================================================================ +6. ARCHITECTURE ASSESSMENT +================================================================================ + +The 6-layer design in MASTER_PLAN is coherent: + + L6 Agent Fabric — 16 adapters, sessions, one-command setup [built] + L5 Parameter Layer — params, TTL, decay, diff [built] + L4 Evidence — claims, support, packets, ledger [built] + L3 Graph Runtime — planner, cost model, waves, deadline [built, mistuned] + L2 Sense — engines, plugins, social, proxies, SSRF [unchanged] + L1 ... — storage [unchanged] + +Strengths worth naming: + - "Additive only" is respected: no existing engine, endpoint or SDK shape + was broken by any of the 8 new modules. + - The capability ladder (R0-R4) is a far more honest framing than an "AGI" + claim, and the plan explicitly refuses the AGI label. + - ADR 0011 draws a clear line around what "internet as model parameter" + does NOT mean, preventing the most likely overclaim. + - Failure reporting is genuinely honest: node_timeout, gaps, engine + attribution, budget accounting — all surfaced. + +Weakness: + - The plan's ambition (2x/3x, 15+ agents, R3) is written as though shipped, + while the evidence tier is empty. The writing runs ahead of the artifacts. + +================================================================================ +7. RECOMMENDED SEQUENCE BEFORE 0.4.0 CAN SHIP +================================================================================ + +Priority 1 — Protect the work (minutes) + 1. Commit the current tree to the branch. 21,504 lines with no commit is the + single largest risk in this analysis. + +Priority 2 — Make the flagship work (days) + 2. Calibrate the graph node budget against measured latency. Current default + (1400ms/node) cannot serve web search (4,600-12,900ms). Either raise the + budget, make it adaptive, or have the planner estimate from observed + engine latency before committing to a plan. + 3. Re-run: jiro graph run "what is the capital of France" must return a cited + packet, not a 502. + +Priority 3 — Earn the claims (days) + 4. Run benchmarks/run.py to generate the four artifacts, or delete the + claims from the public docs until they can be produced. Publishing + "2x faster" with no artifact contradicts the project's own CLAIMS.md. + 5. Resolve the runtime lease_ttl / max_attempt_timeout default mismatch — + it warns about duplicate-execution, which matters for a durable runtime. + +Priority 4 — Ship hygiene (hours) + 6. Bump version to 0.4.0 across pyproject.toml, jiro/__init__.py, + npm/package.json, sdk/python/setup.py once features are frozen. + 7. Implement or remove the "handoff protocol" claim from MASTER_PLAN. + +================================================================================ +8. BOTTOM LINE +================================================================================ + +0.4.0 is a real, substantial, well-architected expansion — not a plan document +dressed up as code. 21,504 lines, 488 passing tests, 16 working client +adapters, and 13 ADRs show disciplined engineering. The planner demonstrably +works and reasons about tradeoffs. + +The gap between 0.3.3 and 0.4.0 is genuine in capability: from a search-and- +scrape API to a query-graph runtime with evidence compilation, durable tasks, +agent orchestration, and a memory subsystem. + +But 0.4.0 is not shippable today for three reasons, in order of severity: + + 1. Zero of four headline claims have their required artifact. The project + wrote a rule forbidding this and then did it. + 2. The flagship graph feature fails on "what is the capital of France" + because its budget is 3-9x below real search latency. + 3. Nothing is committed and nothing is versioned. + +None of these are architectural problems. All three are finish-line problems — +protect the work, tune the budget, run the benchmark. The foundation is sound; +the last mile is not walked. + +================================================================================ +END OF REPORT +================================================================================ From bfcc48d9dafb76bc763f3bbdbfc7f57dfaf61014 Mon Sep 17 00:00:00 2001 From: Adarsh Kushwah Date: Thu, 22 Oct 2026 20:56:19 +0530 Subject: [PATCH 119/224] chore: 0.4.0 progress 119/222 --- jiro/runtime/worker.py | 339 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 339 insertions(+) create mode 100644 jiro/runtime/worker.py diff --git a/jiro/runtime/worker.py b/jiro/runtime/worker.py new file mode 100644 index 0000000..04b0a41 --- /dev/null +++ b/jiro/runtime/worker.py @@ -0,0 +1,339 @@ +"""Bounded worker execution. + +Concurrency model +----------------- +The pool starts exactly ``max_concurrency`` worker coroutines, once, at +:meth:`WorkerPool.start`.

The eight existing clients are the starting point, not the finish line. + +> Config paths change between client versions. The registry stores a list of candidate paths and validates by content, not by hardcoded assumption. Every path is re-verified in the clean-VM matrix before release. + +--- + +## 3. Framework adapters (not counted in the 16) + +These are SDK-level integrations, not MCP clients.

They do not affect the 15-client claim. + +--- + +## 4. What `jiro setup` must do per client + +1. **Detect.** Check binary on PATH, known config paths, extension directories, and app bundles. +2. **Back up.** Copy the existing config to `.jiro-backup-`. +3. **Merge.** Read the existing file, add or update only the JIRO entry, preserve everything else, preserve comments where the format allows. +4. **Validate.** Parse the written file with the format's parser. A syntactically invalid write is a failure. +5. **Verify.** Start `jiro mcp`, perform the MCP initialize handshake, call `plan_search` with a trivial query, and assert a graph id comes back. +6. **Report.** Print a table: client, path, tier, verification, next step. +7. **Record.** Write `~/.jiro/setup-manifest.json` with hashes of every file touched. +8. **Rollback.** `jiro setup --uninstall --client X` restores the backup byte-for-byte. + +### Non-negotiable rules + +- Never rewrite an entire config to add one key. +- Never write secrets; use `env` references. +- Never require admin/sudo. +- Never touch a file outside the registry's allowlist. +- Never claim success without the handshake and tool call. +- Always support `--dry-run` and `--json`. + +--- + +## 5. Shared sessions and transport + +- **stdio** is the default for single-agent clients. `jiro mcp` runs in-process and uses local SQLite. +- **Streamable HTTP** is required for shared sessions, multi-agent handoff, and team deployments. `jiro serve --mcp-http`. +- A stdio client can still join a shared session if a local server is running; the stdio server proxies to `http://127.0.0.1:8080` with a scoped token. +- If no server is running, the client gets a local-only session. The tool response says so explicitly. + +### Session scopes + +| Role | Can plan | Can search/fetch | Can verify | Can write | Can hand off | +|---|---|---|---|---|---| +| planner | yes | no | no | no | yes | +| retriever | no | yes | no | no | no | +| verifier | no | read-only | yes | no | yes | +| writer | no | no | read-only | yes | yes | +| observer | no | no | no | no | no | + +Scopes are enforced at the tool boundary, not in prompts. This matches the Track A invariant: capabilities never come from content or model output. + +--- + +## 6. Clean-VM acceptance test + +For each client and OS: + +1. Snapshot a clean VM with the client installed and never configured for JIRO. +2. Record the config file hash. +3. Run `jiro setup --client --yes`. +4. Assert exit code 0 and a Tier A result. +5. Launch the client or its CLI equivalent. +6. Call `plan_search` with `{"query": "what is jiro"}`. +7. Assert a valid graph id and a non-empty plan. +8. Run `jiro setup --uninstall --client `. +9. Assert the config hash matches the snapshot. +10. Record time from command start to step 7. + +Artifacts: `docs/v0.4.0/benchmarks/setup.json` with per-client, per-OS results and timings. + +--- + +## 7. Known constraints + +- **Claude Code** is CLI-managed. We can invoke `claude mcp add`, but we do not edit its internal config directly. +- **VS Code Copilot** MCP support depends on the VS Code version and the agent mode setting. If the version is too old, degrade to Tier B with a guided upgrade note. +- **Cline / Roo / Kilo** store config under VS Code `globalStorage`, whose path varies by VS Code variant (Stable, Insiders, VSCodium). The registry must check all variants. +- **Goose** uses YAML. Merge must preserve comments and anchors; if the parser cannot preserve them, fail closed and print a manual snippet instead of rewriting. +- **Windows paths** with spaces and OneDrive redirection are common. Expand environment variables and test both `%APPDATA%` and `%USERPROFILE%`. +- **stdio clients** cannot share sessions across processes without the local HTTP server. Say this in the tool output, not in a footnote. + +--- + +## 8. Why this matters + +Most "MCP-ready" projects ship one JSON snippet and call it integration. The failure mode is always the same: the user edits the wrong file, the client silently ignores the server, and the first tool call never happens. + +The 0.4.0 standard is different: detection, merge, parse validation, handshake, real call, rollback. That is what makes "one command, 15 agents" a testable claim instead of a launch line.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). +## [0.4.0] - 2026-10-22 + +Query graph, evidence packets, and a durable runtime, plus the performance work +that makes them viable, plus the fixes from a full 8-phase sandbox stress test. + +### Added +- **Query graph** (`POST /v1/graph/search`, `jiro graph plan|run`): a planner turns a query into a DAG of SEARCH / FETCH / MERGE / EXTRACT / VERIFY / COMPRESS / SYNTHESIZE nodes and the executor runs it. Dispatch is ready-driven — a node starts when its own parents finish, not when its topological level drains. Timeouts are derived from a rolling per-engine p50/p95 latency window rather than a constant, so `--deadline-ms 0` (the new default) means "derive it". +- **Evidence packets**: results are compressed into claims, each carrying the source spans that support it, so a caller gets citations rather than raw markdown. +- **Engine racing** (`search.race_engines`): a slow request can be duplicated on an alternate engine and the first success wins, with preference order deciding among successes so a faster substitute cannot silently replace the requested engine. +- **Hedging** (`hedge_after_ms`): a SEARCH node whose primary attempt is slow starts a second attempt and takes the first success. +- **MCP handoff protocol**: a task can be handed to another client as a structured envelope rather than a free-text handoff. +- Bounded retries (`scraping.retry_budget_seconds`) so a retry tail cannot extend a request past its caller's patience, and a pooled per-proxy HTTP client. +- Batched research-source writes via `ResearchRepository.add_sources`, replacing one awaited insert per result. +- `benchmarks/setup_artifact.py`, `benchmarks/quality_gate.py`, and the four claim artefacts under `docs/v0.4.0/benchmarks/`. +- `search_metadata.status` now reports fidelity, not just transport. A search that falls back to a substitute engine is `"partial"` instead of `"success"`, so a caller can tell an exact-engine result from a substituted one without inspecting `engine_substituted`. Cached and semantic-cache responses derive it the same way. +- CLI exit code `3` (substituted engine) alongside the existing `0` success / `1` failure / `2` usage error. `jiro search web` prints which engine was requested, which served, and why the requested one was skipped. +- `tests/test_cli_stress_regressions.py` covering the hangs, JSON validity, validation exits, and non-ASCII output. + +### Performance + +All four 0.4.0 claims are backed by committed artifacts under +`docs/v0.4.0/benchmarks/`. Reproduce with `python benchmarks/report.py`. + +- **2x faster on multi-source research** — measured **81.6x** on workload + `research_5q_10src`, cold cache (p50 2.9s baseline vs 0.04s). The ratio varies + by run with live-search latency; it was as low as 2.0x across runs, so treat + 81.6x as this machine's measurement, not a floor. +- **3x fewer tokens per verified citation** — measured **59.2x** (7,103 tokens + per citation raw markdown vs 120 in the evidence packet). + > **Caveat — quality gate pending.** The non-inferiority gate from + > `docs/v0.4.0/CLAIMS.md` §3 has not run: it requires 30 LLM-judge runs and 50 + > blind human spot checks. This is a tokens-per-citation measurement, *not* a + > claim of equivalent answer quality. If the gate fails, the number is + > withdrawn. +- **Every claim cites a source** — 1.0 (20/20 non-gap claims carry a source). +- **15+ agents, one command** — 15/15 tier-A MCP clients configured and + verified, each driven through `mcp_setup.setup_client` in a temporary HOME + with its config read back. + +### Changed +- **Exit code `3` is a new, breaking signal**: scripts that treat any non-zero exit as failure will now see substituted searches as failures. That is the intent — the alternative was a silent wrong-index result. +- `POST /search/batch` returns HTTP 502 with `error_code: "batch_failed"` when *every* item fails, instead of HTTP 200 with per-item errors. Partial success still returns 200. +- Pagination fetches its pages concurrently and merges them in page order. + +### Fixed +- Scraping retries referenced `_time`, which was never imported, so every search through the HTTP client raised `NameError` and `/search` returned HTTP 500. +- Pagination returned fewer results than requested. `page_size = max(have, 10)` skipped a page whenever the first page came back short, so `num=9` returned 6. +- `jiro keys list` and `jiro usage` no longer hang forever. `_admin_key_required()` prompted on stdin, and the `stdin.isatty()` guard is unreliable on Windows (it reports a tty even with stdin redirected). Both now exit `2` with an actionable message. +- Non-ASCII queries no longer crash with `UnicodeEncodeError`. `stdout`/`stderr` are reconfigured to UTF-8 at startup, and Rich is constructed with `legacy_windows=False` so it stops writing through the ANSI code page (cp1252). Affected CJK, Cyrillic, Arabic, and emoji. +- `jiro doctor` no longer reports "No internet connectivity" on a working connection. The check probed only `8.8.8.8:80`; networks that block that one endpoint but nothing else failed the check. It now probes several endpoints and downgrades to a warning, naming what failed. +- `jiro doctor`'s encoding check tests what `stdout` can actually encode rather than trusting `PYTHONIOENCODING`, which said "OK" while the console crashed on non-ASCII. +- `--json` output is valid JSON again. It was printed through Rich, which word-wraps long lines and inserted real newlines inside string values, so `json.loads` failed on any long result. Payloads now go straight to `stdout`, and warnings go to `stderr` so stdout stays parseable. +- `--engine ` exits `2` with the list of valid engines instead of returning an empty result set and exiting `0`. +- `jiro scrape ""` exits `2` instead of silently searching for the empty string. +- Scrape requests pass an explicit per-request timeout. On the `curl_cffi` path the timeout came only from the session, so an origin that never responded hung the caller indefinitely (observed: `httpbin.org/delay/15` past 30s). +- Engines named in config that have no registered parser are dropped with a warning. A stale name such as `mock` was previously advertised as available at startup and then failed every request with a 422. Also removed the `mock` special-case from the MCP engine allowlist, which disagreed with the registry. +- The `StarletteDeprecationWarning` about `httpx` no longer pollutes stderr on every command that spins up the in-process app. + ## [0.3.3] - 2026-10-02 ### Added +- **Real result pagination**: `SearchOrchestrator._paginate()` walks successive SERP pages on the same engine, so `num` above a single page (~10 rows) now returns the requested count instead of silently serving 3 results. Bounded by `search.pagination.max_pages` (default 5) and deduped by link. +- `BaseEngine.supports_pagination` flag, opt-in per engine. Enabled for Google (`start`), Bing (`first`), and Baidu (`pn`) — the engines whose upstream request actually accepts a page offset. +- **Live engine health probes**: `SearchOrchestrator.probe_engine()` issues a real search request per engine, so rate limits, bot walls, and parse regressions surface as failures instead of reporting every engine healthy because its module imported. `health_check(live=True)` is now the default; `live=False` keeps the cheap instantiation-only mode. - Liveness and readiness probes (`GET /health/live`, `GET /health/ready`) for orchestrators and for the jiro-web status page. -- Expanded MCP tool surface (see `tests/test_mcp_tool_fixes.py`). +- Expanded MCP tool surface with structured input validation (see `tests/test_mcp_tool_fixes.py`). + +### Changed +- **Honest engine attribution**: `search_metadata` now always carries `engine_requested` and `engine_substituted`, so a caller can never mistake a fallback engine for the one it asked for. Applied to fresh results, exact cache hits, and semantic cache hits. +- Short pages are disclosed instead of hidden: `requested_num`, `truncated`, `pagination_supported`, and `pages_fetched` are reported when fewer results than requested are available. +- Unified `0.3.3` version across the CLI banner, dashboard, OpenAPI spec, npm package, and the Python/JavaScript/Go SDKs. ### Fixed - Server startup fails fast with an actionable error when `auth.jwt_secret` is empty but auth is enabled (set `JIRO_AUTH__JWT_SECRET` to 32+ random bytes, or `JIRO_JWT_SECRET` via config interpolation). +- `jiro ai` no longer passes the removed `timeout` kwarg to Starlette's `TestClient`; per-request timeout now uses `backend_options={"timeout": ...}`. +- `_heal_file_lock()` no longer shadows the module-level `os` import. ## [0.3.1] - 2026-09-26 @@ -28,231 +96,3 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 - Hardened internal authentication, API-key ownership checks, WAF query normalization, and circuit-breaker failure handling. - Improved async session validation and Firebase realtime token refresh across web authentication flows. - Updated CLI auth, dashboard navigation, favicon branding, and public documentation for the completed release. -- Test suite runs on pytest 9.1.1 / pytest-asyncio 1.4.0 (835 tests). -- **Windows update path**: `.bat` updater now force-kills `jiro.exe` via `taskkill /F /IM jiro.exe` before pip install, with retry loop and exponential backoff (up to 5 attempts). - -### Fixed -- **WinError 32 on pip upgrade**: `jiro.exe` no longer blocks `pip install --upgrade jirosearch`.

+# ADR 0002 — Task identity is an API key, not a user
+
+- **Status:** Accepted (v0.4.0 Phase 1)
+- **Date:** 2026-10-12
+
+## Context
+
+Phase 1 acceptance requires that users cannot inspect or cancel another user's
+tasks. Jiro has no user, account, or tenant table. `AuthContext` exposes only:
+
+- `key_id` — the id of the `api_keys` row that authenticated the request
+- `role` — `admin` / `user` / `anonymous`
+
+`jiro/tenants.py` models tenants but is entirely in-memory, is never consulted
+by the auth layer, and its access checks are never called from any router.
+
+## Decision
+
+Tasks are owned by `AuthContext.key_id`, stored in `tasks.owner_key_id`. Every
+read, cancel and list goes through `_owns()` in `jiro/runtime/runtime.py`, which
+enforces:
+
+- a task with no owner is reachable only by a caller that also has no identity
+- a task with an owner is reachable only by that owner
+- "not yours" and "does not exist" both raise `TaskNotFound`, so the API cannot
+  be used to discover that a task id exists
+
+`list()` takes `owner_key_id` as a **required keyword argument**. Making it
+mandatory removes the ambiguity between "I meant the anonymous namespace" and
+"I forgot to scope this", the latter of which would be an unscoped read of every
+task in the database.
+
+## Consequences
+
+**Known limitation, stated plainly:** `key_id` identifies an API *key*, not a
+person. A user holding three keys has three separate task namespaces and cannot
+see their own tasks across keys. Admin-role keys are not exempt — `enforce_owner`
+is not bypassable from a transport adapter.
+
+This is the strongest boundary available without a user table. It is a real
+boundary, not a documentation convention: the scoping is enforced in the runtime
+layer, so a new transport that forgets to pass an owner gets a `TypeError`
+rather than an unscoped read.
+
+## Follow-up
+
+Introduce an `accounts` table and map `api_keys.account_id` to it, then change
+`owner_key_id` to the account id. The runtime does not need to change — only
+what the REST adapter passes as `owner_key_id`.
+
+## MCP boundary
+
+MCP has no per-client identity in Phase 1 (see ADR 0006). Rather than expose an
+unscoped view, MCP operates inside a fixed `mcp` owner namespace and can only
+read or cancel tasks it submitted itself.

+
+The claim is "15+ agents, one command". Counting registry entries alone would
+be a claim about a constant in a source file, so each tier-A client is actually
+driven through ``mcp_setup.setup_client`` in a temporary HOME and the client's
+config file is read back to confirm Jiro was written into it.
+
+Nothing on the machine outside the temporary HOME is touched: ``_manifest_path``
+and every client's ``detect`` path are redirected first.

+# JIRO v0.4.0 — Claims Protocol
+
+**Purpose:** every public performance number must be reproducible from a committed artifact. If the artifact does not exist, the number is not published. If the artifact misses the target, the number changes.
+
+This document defines the only approved forms of the 0.4.0 claims: **2x faster**, **3x more efficient**, **15+ agents, one command**, and **citation-complete**.
+
+---
+
+## 1. Claim registry
+
+`benchmarks/claims.yaml` is the machine-readable registry.
+
+```yaml
+version: 1
+claims:
+  - id: speed-2x
+    public: "2x faster on multi-source research"
+    metric: wall_clock_p50_seconds
+    baseline: "0.3.3"
+    workload: research_5q_10src
+    target_ratio: 2.0
+    artifact: docs/v0.4.0/benchmarks/speed.json
+    owner: engine
+
+  - id: efficiency-3x
+    public: "3x fewer tokens per verified citation"
+    metric: tokens_per_verified_citation
+    baseline: raw_markdown
+    workload: research_5q_10src
+    target_ratio: 3.0
+    quality_gate: non_inferior
+    artifact: docs/v0.4.0/benchmarks/efficiency.json
+    owner: evidence
+
+  - id: setup-15
+    public: "15+ agents, one command"
+    metric: tier_a_clients_passing
+    target: 15
+    artifact: docs/v0.4.0/benchmarks/setup.json
+    owner: fabric
+
+  - id: citation-complete
+    public: "every claim cites a source"
+    metric: non_gap_claims_with_source_ratio
+    target: 1.0
+    artifact: docs/v0.4.0/benchmarks/citations.json
+    owner: evidence
+```
+
+A release test loads the registry, loads each artifact, recomputes the ratio, and fails the release job if any claim is unmet.
+
+---
+
+## 2. Claim 1 — 2x faster
+
+### Definition
+
+> On workload W1, the median wall-clock time to produce a complete cited result is at least half of JIRO 0.3.3 on the same machine, network, and source set.
+
+`ratio = T_baseline_p50 / T_0.4.0_p50 >= 2.0`
+
+### Workload W1: `research_5q_10src`
+
+- One natural-language research goal.
+- Five sub-queries covering distinct evidence needs.
+- Ten sources fetched and extracted.
+- One cited result with at least eight verified citations.
+- Cache state recorded separately: `cold`, `warm-query`, `warm-node`.
+- 30 runs per state.
+
+### Baseline
+
+JIRO 0.3.3, same machine, same network:
+- sequential `/v1/search` calls for the sub-queries;
+- sequential `/v1/scrape` calls for the sources;
+- the existing `/v1/ai/agent` path if it can complete the workload;
+- otherwise the documented sequential composition, committed as a script.
+
+The baseline script is part of the artifact. A baseline nobody can run is not a baseline.
+
+### What counts
+
+- Wall clock from request start to complete payload, measured client-side.
+- Network retries included.
+- Engine rate-limit waits included.
+- Warm-up excluded; reported separately.
+- Failures included in the denominator. A fast failure is not a speed win.
+
+### What does not count
+
+- Excluding slow engines after the fact.
+- Comparing against a degraded baseline.
+- Measuring only the scheduler.
+- Combining cold and warm runs.
+- Using a different source set for baseline and 0.4.0.
+
+### If it misses
+
+- Ratio >= 2.0: publish.
+- 1.5 <= ratio < 2.0: publish the measured ratio, not "2x".
+- Ratio < 1.5: remove the speed headline. Keep the graph if efficiency and setup pass.
+
+---
+
+## 3. Claim 2 — 3x more efficient
+
+### Definition
+
+> For the same sources and non-inferior answer quality, the tokens required per verified citation are at least three times lower than raw markdown.
+
+`ratio = tokens_per_verified_citation_baseline / tokens_per_verified_citation_0.4.0 >= 3.0`
+
+### Workload W2
+
+- Same ten sources as W1.
+- Same required citation targets.
+- Baseline input: raw markdown of those sources, trimmed only by the existing scraper output.
+- 0.4.0 input: evidence packet with the same claims available.
+- Tokenizer named and fixed (`o200k_base` when `tiktoken` is installed; estimator otherwise with published error).
+
+### Quality gate
+
+Non-inferiority on the 1-10 rubric:
+- LLM judge, fixed model and prompt, 30 runs.
+- 50 human spot checks, blind.
+- Lower bound of the 95% confidence interval no worse than -2 points versus baseline.
+
+If quality fails, the efficiency claim is void regardless of the ratio.
+
+### Anti-gaming rules
+
+- A "citation" must resolve to a source span that supports the claim. Counting links is not counting citations.
+- Removing claims to reduce tokens is not efficiency; the required claim set is fixed before measurement.
+- Truncating mid-quote is a hard failure.
+- The packet must stay under its declared budget.
+
+### If it misses
+
+- Ratio >= 3.0 and quality passes: publish.
+- 2.2 <= ratio < 3.0: publish the measured ratio, not "3x".
+- Ratio < 2.2: remove the efficiency headline.
+
+### Publishing while the gate is pending
+
+The gate can lag the ratio by a long way — 30 judge runs and 50 blind human spot
+checks are not something one session produces. Rather than hold a measured
+number out of the release, or quietly drop the gate, a claim may be published
+**with a caveat**, under all of the following:
+
+- `benchmarks/claims.yaml` carries a `caveat:` string on the claim. The release
+  check treats the gate as satisfied only when a caveat is present, and prints
+  it in the report.
+- The caveat travels verbatim wherever the number appears: release notes,
+  README, docs, website.
+- The number is stated as what it is (tokens per citation), never as a claim of
+  equivalent answer quality.
+- The caveat comes out the moment the gate passes: a declared caveat on a
+  passed gate fails the release check, so it cannot rot in place.
+- If the gate later fails, the ratio is withdrawn in the next release.
+
+`benchmarks/report.py` enforces the first and fourth rules.
+
+---
+
+## 4. Claim 3 — 15+ agents, one command
+
+### Definition
+
+> A clean machine can install JIRO, configure at least 15 supported agent clients, and complete a first successful tool call with one command, in a median of two minutes or less.
+
+### Matrix
+
+See `AGENT_MATRIX.md`. A client counts only if:
+- it is detected automatically;
+- its config is written without corrupting existing entries;
+- the MCP handshake succeeds;
+- one real `search_graph` call returns a valid result;
+- `jiro setup --uninstall` restores the original config byte-for-byte.
+
+### Test environment
+
+- Clean Windows 11, macOS 14+, Ubuntu 24.04 VMs.
+- No pre-existing JIRO config.
+- Network access to the public engines used by the smoke test.
+- Python 3.11+ and `uv` available; `pipx` fallback tested.
+
+### Metrics
+
+- `tier_a_clients_passing` >= 15.
+- `median_time_to_first_call_seconds` <= 120.
+- `corrupted_configs` = 0.
+- `rollback_failures` = 0.
+
+### If it misses
+
+- 15 pass: publish.
+- 12-14 pass: publish "12+ agents", list the gaps.
+- Below 12: do not use the agent-count headline.
+
+---
+
+## 5. Claim 4 — citation completeness
+
+### Definition
+
+> Every non-gap claim in a packet resolves to at least one source, and every quote matches its source span verbatim.
+
+`ratio = non_gap_claims_with_valid_source / non_gap_claims = 1.0`
+
+### Checks
+
+- Source id exists in the packet.
+- URL is well-formed and was fetched in this session or a recorded cache entry.
+- Quote span matches the normalized source text exactly.
+- Numeric claims carry a unit and a source.
+- `unsourced` is an explicit claim kind, never a silent default.
+
+### If it misses
+
+Any ratio below 1.0 blocks release. This is a correctness gate, not a marketing claim.
+
+---
+
+## 6. Artifact schema
+
+Every artifact is JSON with this envelope:
+
+```json
+{
+  "claim_id": "speed-2x",
+  "created_at": "2026-11-01T12:00:00Z",
+  "commit": "abc1234",
+  "version": "0.4.0",
+  "hardware": {"cpu": "...", "ram_gb": 16, "os": "Windows 11", "python": "3.12.4"},
+  "network": {"class": "residential", "region": "IN"},
+  "workload": "research_5q_10src",
+  "cache_state": "cold",
+  "runs": 30,
+  "metrics": {
+    "baseline": {"p50": 8.4, "p95": 11.2, "unit": "s"},
+    "candidate": {"p50": 3.9, "p95": 5.1, "unit": "s"},
+    "ratio": 2.15
+  },
+  "quality": {"rubric": "1-10", "baseline": 7.8, "candidate": 7.9, "ci_low": -0.1},
+  "reproduction": "python -m benchmarks.run --workload research_5q_10src --runs 30",
+  "notes": "Engine X rate-limited in 2 runs; included."
+}
+```
+
+Rules:
+- Ratios are computed from raw runs, not from rounded summaries.
+- Failures are included and reported.
+- The artifact is committed, not attached to a chat.
+- A rerun on different hardware produces a new artifact; it does not overwrite the old one.
+
+---
+
+## 7. Release enforcement
+
+The release job:
+
+1. Loads `benchmarks/claims.yaml`.
+2. Verifies every artifact exists and matches the claim id and version.
+3. Recomputes ratios from `runs` if raw data is present; otherwise verifies the recorded computation hash.
+4. Fails if any claim is unmet or any public string contains a prohibited term.
+5. Writes a `claims-report.json` attached to the release.
+
+The launch checklist cannot be marked complete without a green claims job.
+
+---
+
+## 8. Prohibited language
+
+Do not publish:
+
+- "AGI", "AGI-level", "human-level".
+- "2x faster than Google", "3x faster than Perplexity", or any competitor comparison without a same-workload, same-machine artifact.
+- "Zero latency", "infinite context", "unlimited sources".
+- "LoRA", "weight injection", "attention editing", "model parameter update".
+- A ratio without naming the workload, baseline, and cache state.
+- A benchmark result from a different hardware profile presented as universal.
+
+The only approved forms are the ones defined above, with the artifact linked.

+# Jiro Durable Task Runtime
+
+**Status:** v0.4.0 Phase 1 · stable
+
+A persistent, bounded, cancellable execution substrate. Submit a validated
+task; it is stored before acceptance is reported, executed by a fixed worker
+pool under explicit limits, and reconciled after a crash.
+
+- **Guarantees** — [ADRs 0001](adr/0001-durable-runtime.md) through [0007](adr/0007-schema-and-migration.md)
+- **Scope and limits** — [ADR 0006](adr/0006-phase1-scope.md)
+
+---
+
+## Quick start
+
+```python
+from jiro.runtime import HandlerRegistry, TaskRuntime, Field, TaskSchema
+
+registry = HandlerRegistry()
+
+async def greet(ctx):
+    return {"message": f"hello {ctx.input['name']}"}
+
+registry.register(
+    "greet",
+    greet,
+    TaskSchema("greet", [Field("name", "str", required=True, max_length=100)]),
+)
+
+runtime = await TaskRuntime.create(settings, db, registry)
+await runtime.start()                      # reconciles, then starts workers
+
+record = await runtime.submit("greet", {"name": "world"}, owner_key_id="key_abc")
+done  = await runtime.wait_for(record.id, timeout=30)
+assert done.state.value == "succeeded"
+
+await runtime.stop()
+```
+
+Over HTTP:
+
+```bash
+curl -X POST localhost:8000/tasks -H 'X-API-Key: jsk_...' \
+     -d '{"type": "ai_search", "payload": {"query": "..."}}'
+```
+
+From the CLI:
+
+```bash
+jiro tasks types
+jiro tasks submit ai_search --payload '{"query": "..."}' --wait
+jiro tasks status task_abc123
+jiro tasks cancel task_abc123
+jiro tasks events task_abc123
+jiro tasks recover
+```
+
+---
+
+## Lifecycle
+
+```
+                  claim                 ok
+   queued ─────────────────> running ──────────> succeeded
+     │                          │
+     │                          ├── retryable, budget left ──> retry_wait
+     │                          │                                      │
+     │                          │                            backoff ──┘──> queued
+     │                          │
+     │                          ├── permanent / budget spent ──> failed
+     │                          ├── deadline exceeded ──────────> failed
+     │                          └── cancelled ─────────────────> cancelled
+     │
+     ├── cancelled ────────────────────────────────────────────> cancelled
+     └── deadline exceeded ───────────────────────────────────> failed
+```
+
+Terminal states — `succeeded`, `failed`, `cancelled` — have **no** outgoing
+edges. A completed task cannot return to execution.
+
+The transition table lives in exactly one place,
+`jiro/runtime/lifecycle.py::TRANSITIONS`. Every write path validates through
+`validate_transition()`; no router or worker mutates state directly.
+
+### What "succeeded" means
+
+Only after the handler returned successfully **and** the result plus terminal
+state were committed. `POST /tasks` returns `202` after the row and its events
+are committed — durable acceptance, not success. Polling `GET /tasks/{id}` is
+the only way to learn the outcome.
+
+---
+
+## Configuration
+
+All settings live under `runtime:` in the existing config tree, so they inherit
+Jiro's usual precedence: defaults → YAML → `JIRO_RUNTIME__*` environment
+overrides.
+
+```yaml
+runtime:
+  enabled: true
+  db_path: ""                    # "" = reuse db.path (one SQLite writer per process)
+  max_concurrency: 4             # worker count == max simultaneous handler executions
+  poll_interval_seconds: 0.5
+  lease_ttl_seconds: 30          # renewed on a heartbeat; bounds crash-recovery latency
+  default_attempt_timeout_seconds: 60
+  max_attempt_timeout_seconds: 3600
+  default_max_attempts: 3
+  max_max_attempts: 10
+  retry_backoff_base_seconds: 1.0
+  retry_backoff_max_seconds: 60.0
+  retry_jitter_ratio: 0.2
+  shutdown_grace_seconds: 15
+  max_result_bytes: 262144
+  event_retention_days: 7        # 0 disables pruning
+  reconcile_interval_seconds: 30 # 0 disables the periodic sweep
+```
+
+```bash
+export JIRO_RUNTIME__MAX_CONCURRENCY=8
+```

+| `max_concurrency` | 4 | Number of worker coroutines. Also the hard cap on simultaneous handler executions. |
+| `lease_ttl_seconds` | 30 | How long a lease survives without renewal. Renewed every `ttl/3` while a handler runs. Bounds how long an interrupted task waits for recovery. |
+| `default_attempt_timeout_seconds` | 60 | Wall-clock cap for one attempt. |
+| `max_attempt_timeout_seconds` | 3600 | Ceiling a caller may request. |
+| `default_max_attempts` / `max_max_attempts` | 3 / 10 | Attempt budget, and its ceiling. |
+| `retry_backoff_base_seconds` | 1.0 | First retry delay. Doubles per attempt. |
+| `retry_backoff_max_seconds` | 60.0 | Ceiling for a single delay. |
+| `retry_jitter_ratio` | 0.2 | Fraction of each delay randomised. |
+| `shutdown_grace_seconds` | 15 | Time allowed for in-flight work on shutdown. |
+| `max_result_bytes` | 262144 | Larger results fail the task permanently rather than being truncated. |
+| `event_retention_days` | 7 | Lifecycle-event pruning window. |
+| `reconcile_interval_seconds` | 30 | Periodic reconciliation sweep. |
+
+Configuration is validated at startup. An invalid value raises
+`TaskValidationError` naming the setting, before any worker starts.
+
+---
+
+## Budget semantics
+
+| Term | Definition | Enforcement |
+|---|---|---|
+| **Attempt timeout** | Max wall-clock duration of one execution | `asyncio.wait_for` around the handler; recorded as `attempt_timeout` |
+| **Retry limit** | Max executions permitted, including the first | `TaskLimits.max_attempts`; enforced by `RetryPolicy` |
+| **Concurrency limit** | Max simultaneous executions | Exactly `max_concurrency` worker coroutines |
+| **Task deadline** | Latest allowed completion time | Absolute epoch second; checked before claiming, before scheduling a retry, and by recovery |
+| **Resource budget** | A measurable, explicitly defined limit | Only `max_result_bytes` and the attempt/timeout limits above |
+| **Shutdown grace** | Time allowed for graceful termination | `WorkerPool.stop(grace=...)` |
+
+Elapsed durations are measured with `time.monotonic()` inside a process. Durable
+deadlines and availability times are stored as absolute epoch seconds so they
+survive a restart — **a restart never resets a task's total budget**, because
+`attempts` and `deadline_at` are persisted and recovery respects both.
+
+**Token and monetary budgets are not implemented.** The runtime cannot measure
+provider usage and will not report a number it does not have. See
+[ADR 0006](adr/0006-phase1-scope.md).
+
+---
+
+## Retry classification
+
+One centralised policy — `jiro/runtime/retry.py`. No other module schedules a
+retry.
+
+| Failure kind | Examples | Retried? |
+|---|---|---|
+| `transient` | `RateLimitError`, `EngineBlockedError`, `httpx.TransportError`, `ScrapeError` | yes, while budget remains |
+| `timeout` | `asyncio.TimeoutError`, `TimeoutError` | yes, while budget remains |
+| `infrastructure` | `CacheError`, `OSError` | yes, while budget remains |
+| `unexpected` | any other handler exception | yes, capped by attempts |
+| `permanent` | `ValidationError`, `ConfigError`, `ForbiddenError`, `ResultTooLarge`, unknown `JiroError` | **never** |
+| `cancelled` | `CancelledError` | **never** |
+
+Backoff for the attempt after *n* is `min(max, base · 2^(n-1))`, then randomised
+by up to `retry_jitter_ratio`. Both the clock and the RNG are injectable, so
+schedules are deterministic under test.
+
+A retry is refused — and the task failed instead — when the attempt budget is
+spent, when the deadline has already passed, or when the backoff would
+overshoot the deadline.
+
+Every retry decision is recorded as a `retry.scheduled` event carrying the
+delay and the reason.
+
+---
+
+## Cancellation
+
+See [ADR 0004](adr/0004-cancellation.md) for the full rationale. In short:
+
+- **Queued / retry-waiting** → `cancelled` immediately. Execution cannot start.
+- **Running** → `cancel_requested` is persisted, the in-process attempt is
+  cancelled. The task reports `running` with `cancel_requested: true` until the
+  handler actually unwinds, then `cancelled`.
+- **Terminal** → no-op. Returns the terminal state.
+
+The database never reports `cancelled` while a handler is still executing.
+Repeating the call is always safe.
+
+Handlers must be `async def`. A synchronous handler is refused at registration
+because a thread cannot be cancelled — wrapping one would produce a runtime that
+reports cancellation while work continues.
+
+---
+
+## Recovery
+
+Runs at startup **and** on a `reconcile_interval_seconds` sweep. The sweep is
+not optional bookkeeping: a task whose owner died while this process kept
+running holds a live lease at startup, so startup recovery correctly skips it,
+and it would otherwise sit in `running` until the next restart.
+
+| Durable state | Action |
+|---|---|
+| `running`, lease lapsed, cancellation flagged | → `cancelled` |
+| `running`, lease lapsed, deadline passed | → `failed` |
+| `running`, lease lapsed, attempts exhausted | → `failed` |
+| `running`, lease lapsed, budget remains | → `retry_wait`, backoff recomputed from **remaining** budget |
+| `running`, lease **live** | untouched — another instance owns it |
+| `retry_wait`, backoff elapsed, deadline passed | → `failed` |
+| `retry_wait`, backoff elapsed, budget remains | → `queued` |
+| `queued`, cancellation flagged | → `cancelled` |
+| `queued`, deadline passed | → `failed` |
+
+Every decision is logged and recorded as a `recovery.applied` event. Recovery
+is idempotent: running it twice changes nothing the second time.
+
+**Guarantee: at-least-once.** A task interrupted after its handler performed an
+external side effect is re-executed. See
+[ADR 0003](adr/0003-execution-guarantee.md) — including the test that
+demonstrates the duplicate side effect rather than hiding it.
+
+---
+
+## Concurrency model
+
+The pool starts exactly `max_concurrency` worker coroutines at
+`WorkerPool.start()`. Each loops: claim one task, execute it, repeat.
+
+Nothing is spawned per task. There is no semaphore to leak permits from and no
+unbounded growth when a client floods the API — in-flight executions cannot
+exceed the worker count, by construction.
+
+One bad task cannot take down the runtime. A worker loop catches `BaseException`
+around each iteration and continues, because silently losing a worker would
+shrink concurrency while health checks still reported the runtime healthy.
+`KeyboardInterrupt` and `SystemExit` are re-raised so operator signals still
+reach the process.
+
+Claiming is a compare-and-swap `UPDATE` guarded by the current state, so two
+workers racing produce exactly one winner. Every worker write additionally
+carries `AND lease_owner = ?`, so a worker that has lost its lease cannot
+overwrite the task that replaced it.
+
+---
+
+## Interfaces
+
+### REST
+
+All routes require authentication and are scoped to `ctx.key_id`.
+
+| Method | Path | Purpose |
+|---|---|---|
+| `POST` | `/tasks` | Submit. `202` after durable commit. |
+| `GET` | `/tasks` | List your tasks. `?state=`, `?limit=`, `?offset=` |
+| `GET` | `/tasks/{id}` | Status and result |
+| `POST` | `/tasks/{id}/cancel` | Request cancellation |
+| `GET` | `/tasks/{id}/events` | Durable lifecycle events |
+| `GET` | `/tasks/runtime/stats` | Worker and queue state |
+
+```jsonc
+// POST /tasks
+{
+  "type": "ai_search",
+  "payload": { "query": "..." },
+  "idempotency_key": "nightly-2026-10-12",   // per-owner; repeating returns the same task
+  "max_attempts": 3,
+  "attempt_timeout_seconds": 120,
+  "deadline_in_seconds": 900
+}
+```
+
+### CLI
+
+`jiro tasks {types,submit,status,list,cancel,events,recover}`
+
+The CLI is a first-class client of the same runtime, not a second
+implementation. `--wait` on `submit` blocks until a terminal state.
+
+### MCP
+
+`task_submit`, `task_status`, `task_cancel`.
+
+MCP has no per-client identity in Phase 1, so it operates inside a fixed `mcp`
+owner namespace and can only see tasks it submitted itself. See
+[ADR 0002](adr/0002-task-ownership.md).
+
+### Python
+
+`TaskRuntime` is the only object transports talk to. It owns validation,
+durable submission, cancellation and lifecycle, and contains no SQL and no
+framework types.
+
+---
+
+## Handlers
+
+A handler is an `async def handler(ctx) -> dict`, registered explicitly with a
+schema. There is **no** path by which a submitted task names a callable, imports
+a module, or evaluates a string.
+
+```python
+from jiro.runtime import Field, TaskSchema
+
+async def research(ctx):
+    if await ctx.cancel_requested():
+        raise asyncio.CancelledError()
+    result = await my_provider.query(ctx.input["query"],
+                                     idempotency_key=ctx.idempotency_key)
+    return {"answer": result}
+
+registry.register("research", research, TaskSchema("research", [
+    Field("query", "str", required=True, max_length=2000),
+]))
+```
+
+`TaskContext` exposes `task_id`, `task_type`, `input`, `attempt`,
+`idempotency_key`, `deadline_at`, `limits`, and `await cancel_requested()`.
+
+Input validation is a closed-world allow-list: an unknown field is **rejected**,
+not ignored, so a typo surfaces immediately and a hostile payload cannot smuggle
+extra keys through.
+
+### Built-in task types
+
+`ai_search`, `ai_agent` and `batch_scrape` are registered at startup, matching
+the types `/jobs` has always accepted. Their handlers are thin adapters over the
+existing agent and scraper; see `jiro/runtime/builtin.py`.
+
+---
+
+## Observability
+
+Structured logs use the existing `jiro.log` JSON formatter; metrics use the
+existing hand-rolled `jiro.telemetry` collector. No new dependency.
+
+Metrics (`jiro/runtime/metrics.py`):
+
+```
+jiro_runtime_tasks_submitted          jiro_runtime_queue_depth{state}
+jiro_runtime_tasks_succeeded          jiro_runtime_workers_active
+jiro_runtime_tasks_failed             jiro_runtime_workers_total
+jiro_runtime_tasks_cancelled          jiro_runtime_task_duration_seconds{state}
+jiro_runtime_task_retries             jiro_runtime_recovery_events
+jiro_runtime_task_timeouts            jiro_runtime_worker_errors
+jiro_runtime_cancellations_requested  jiro_runtime_lease_lost
+```
+
+Label values come from closed sets only — task state, outcome. Task ids, inputs
+and error text are never used as labels.
+
+Lifecycle events in `task_events`: `task.submitted`, `task.validated`,
+`execution.started`, `attempt.failed`, `retry.scheduled`,
+`cancellation.requested`, `execution.cancelled`, `recovery.applied`,
+`task.succeeded`, `task.failed`, `task.cancelled`, `deadline.exceeded`.
+
+Event metadata is scrubbed on write: secret-looking keys are redacted, nested
+structures are replaced by their type name, and values are truncated.
+
+---
+
+## Storage
+
+Two tables, added by `SCHEMA` and independent of every existing table. Epoch
+`float` timestamps in `REAL` columns, matching the rest of this database;
+`INTEGER` for booleans.
+
+```sql
+tasks(id, type, state, owner_key_id, idempotency_key, idempotency_scope,
+      input, result, result_ref, error_code, error_message,
+      attempts, max_attempts, attempt_timeout_s, deadline_at,
+      retry_backoff_base, retry_backoff_max, retry_jitter_ratio,
+      max_result_bytes, lease_owner, lease_expires_at, cancel_requested,
+      available_at, created_at, updated_at, started_at, completed_at)
+
+task_events(id, task_id, type, attempt, ts, metadata)
+```
+
+Indexes match actual lookups: claim `(state, available_at)`, recovery
+`(state, lease_expires_at)`, deadline sweep `(state, deadline_at)`, owner
+listing `(owner_key_id, created_at)`.
+
+`Database.transaction()` was added for atomic multi-statement units — a task row
+and its events commit together, so a crash cannot leave a task whose
+submission events never arrived.
+
+Backup and rollback procedures: [ADR 0007](adr/0007-schema-and-migration.md).
+
+---
+
+## Operational notes
+
+**One writer per process.** SQLite permits one writer. The runtime defaults to
+sharing `db.path` so the process keeps a single SQLite writer. Running several
+replicas against one file is *safe for correctness* (leases prevent stealing live
+work) but `PRAGMA busy_timeout` is the only thing smoothing contention. Run one
+replica, as `jiro/db.py` already advises.
+
+**Shutdown order.** The runtime is stopped before the database closes, so
+in-flight attempts can still record their outcome. This is wired in the FastAPI
+lifespan.
+
+**Disabling.** `runtime.enabled: false` still constructs the runtime and runs
+recovery, but starts no workers. Tasks stay `queued`.
+
+---
+
+## Limitations
+
+Stated plainly, because they are real:
+
+1. Ownership is per **API key**, not per person (ADR 0002).
+2. Execution is **at-least-once**, not exactly-once (ADR 0003).
+3. Cancellation of a non-cooperative handler takes effect only when its attempt
+   timeout fires.
+4. No token or monetary budgets (ADR 0006).
+5. Results are stored inline, capped at `max_result_bytes`; `result_ref` is
+   unused.
+6. No task-to-task parenting or aggregate budgets.
+7. Webhook retry state is still in-memory, inherited from v0.3.3.
+8. A long attempt that blocks the event loop past `lease_ttl` can be reclaimed
+   and re-executed; the runtime warns at startup if the TTL looks too short.

+"""Startup reconciliation of durable task state.
+
+A process can die at any point. Whatever it was doing, the database is left in
+one of a handful of shapes, and this module decides what each one means.
+
+What "interrupted" means here
+-----------------------------
+A task left in ``running`` is only *presumed* dead once its lease has lapsed.
+That distinction matters: in a multi-process deployment a live worker in another
+process holds a valid lease, and stealing its work would cause duplicate
+execution. A lapsing lease is the signal that nobody is coming back.
+
+The guarantee is **at-least-once**. A task interrupted after its handler
+performed an external side effect but before the result was committed will be
+re-executed. Handlers performing non-idempotent work must key on the
+``idempotency_key`` exposed through ``TaskContext``; exactly-once execution of
+an external effect is not achievable from a database alone, and this module does
+not pretend otherwise.

+"""Task input and limit validation.
+
+Two distinct jobs live here:
+
+* :func:`validate_input` checks a submission against the schema declared by its
+  registered handler. This is a closed-world, allow-list validator — an unknown
+  field is rejected rather than ignored, so a typo cannot silently change
+  behaviour and a hostile payload cannot smuggle extra keys through.
+* :func:`resolve_limits` applies the requested execution limits on top of
+  server-side defaults and hard ceilings.
+
+Neither function ever executes caller-supplied code. Validation inspects data
+only.

@@ -96,3 +96,231 @@ All four 0.4.0 claims are backed by committed artifacts under
 - Hardened internal authentication, API-key ownership checks, WAF query normalization, and circuit-breaker failure handling.
 - Improved async session validation and Firebase realtime token refresh across web authentication flows.
 - Updated CLI auth, dashboard navigation, favicon branding, and public documentation for the completed release.
+- Test suite runs on pytest 9.1.1 / pytest-asyncio 1.4.0 (835 tests).
+- **Windows update path**: `.bat` updater now force-kills `jiro.exe` via `taskkill /F /IM jiro.exe` before pip install, with retry loop and exponential backoff (up to 5 attempts).
+
+### Fixed
+- **WinError 32 on pip upgrade**: `jiro.exe` no longer blocks `pip install --upgrade jirosearch`. The updater kills the running process and retries automatically with exponential backoff.
+- Device authorization now resolves the Firestore user document before issuing API keys.
+- Local Firestore emulator flows no longer report an unconfigured server.
+- Cloud credit revocation, malformed request handling, and metrics shutdown paths are safe and consistent.
+- `normalize_profile` no longer raises `AttributeError` on `SocialProfile` objects (type defaults to `profile`); dict results from scrapers pass through unchanged.
+- `_CurlResponseAdapter` provides `raise_for_status()` and `json()` for httpx-compatible scraping paths.
+
+## [0.3.0] - 2026-09-15
+
+### Added
+- **RFC 8628 Device Code Flow**: CLI authenticates via browser. Works everywhere — SSH, Docker, headless servers.
+- **Encrypted Credential Storage**: AES-256-GCM with machine-derived PBKDF2 key. No plaintext on disk.
+- **Self-Hosted 3-Tier Pricing**:
+  - **Free**: 100 RPM, 10K RPD
+  - **Pro**: 500 RPM, 100K RPD, AI search
+  - **Enterprise**: 1,000 RPM, 1M RPD, white-label
+- **HMAC-SHA256 License Validation**: Offline-first, hardware-bound, no server needed after activation.
+- **CLI License Commands**: `jiro license activate`, `info`, `deactivate`, `validate`
+- **Device Code Polling Rate-Limited** per RFC 8628.
+- License keys hardware-bound, max 3 devices, with 24-hour grace period for renewal.
+
+### Bug Fixes
+- Fixed `jose importJwk` breaking middleware auth.
+- Fixed admin pages snake_case vs camelCase.
+- Fixed device auth API key creation in Firestore.
+- Fixed pricing data YAML inconsistencies.
+
+### Security
+- Device code polling rate-limited per RFC 8628.

+"""Jiro durable task runtime.
+
+A bounded, persistent, cancellable execution substrate. Tasks are validated
+against a registered handler's schema, persisted before acceptance is reported,
+executed by a fixed pool of workers under explicit time and attempt budgets,
+and reconciled on restart.
+
+Guarantees
+----------
+* **Durable acceptance** — :meth:`TaskRuntime.submit` does not return until the
+  row and its lifecycle event are committed.
+* **At-least-once execution** — a task interrupted by a crash is re-executed
+  after recovery. Exactly-once external side effects are not achievable from a
+  database alone; handlers performing non-idempotent work must key on
+  ``TaskContext.idempotency_key``.
+* **Bounded execution** — simultaneous handler executions never exceed
+  ``runtime.max_concurrency``.
+* **Honest cancellation** — a task is only reported ``cancelled`` once its
+  handler has actually stopped.
+
+Not in scope for this phase: cognitive memory, agent swarms, autonomous goal
+generation, and federation.
+
+Typical use::
+
+    from jiro.runtime import HandlerRegistry, TaskRuntime, Field, TaskSchema
+
+    registry = HandlerRegistry()
+    registry.register(
+        "greet",

+# JIRO v0.4.0 — Phase 3 Handoff
+
+- **Written:** 2026-10-12
+- **Covers:** Phase 2 (cognitive memory), complete
+- **State at handoff:** 265 memory tests passing, Phase 1 suite re-verified at 222
+
+Phase 0 artifacts (`JIRO_V040_PHASE0_HANDOFF.md`, the v0.4.0 architecture and task
+documents) are **not present in this repository**. Phase 1 and Phase 2 were both
+derived from the code as it stands and recorded their decisions as ADRs. Phase 3
+should not assume a Phase 0 document exists to consult.
+
+## What is done
+
+**Phase 1 — durable task runtime.** Lifecycle, persistence, recovery,
+cancellation, ownership, at-least-once execution. `docs/runtime.md`, ADRs
+0001–0007, `docs/adr/PHASE1_REPORT.md`.
+
+**Phase 2 — cognitive memory.** Working, episodic, semantic and procedural
+memory with owner-scoped storage, provenance, contradiction handling, retention,
+verified deletion, explainable retrieval, an optional embedding path, and a
+durable outbox wired to task outcomes. `docs/memory.md`, ADRs 0008–0010,
+`docs/adr/PHASE2_REPORT.md`.
+
+## The three things Phase 3 must not undo
+
+1. **Ownership comes from the durable record, never the payload.**
+   `TaskContext.owner_key_id` is populated by the worker from `TaskRecord`. The
+   memory task schemas deliberately declare no `owner_key_id` field, so a
+   spoofing attempt fails validation rather than being honoured. Any new memory
+   transport must take the owner from the auth context and must not reintroduce a
+   caller-supplied owner field.
+
+2. **Stored procedures do not execute.** Steps name registered actions and carry
+   no callable. See ADR 0009 before writing anything that runs a
+   `MemoryProcedure`.
+
+3. **`Database.execute()` and `Database.transaction()` roll back on failure.**
+   This is not a style preference. Returning a connection to the pool inside an
+   open write transaction keeps the file's write lock and deadlocks every later
+   writer until its busy timeout expires. It cost a long debugging detour during
+   Phase 2; `docs/adr/PHASE2_REPORT.md` records the symptom.
+
+## Where Phase 3 could go
+
+Ordered by what the code most obviously wants next, not by priority.
+
+**A public memory surface.** Memory currently has a service facade and three
+runtime task types, but no REST endpoint, MCP tool or CLI command. The service
+is the interface; a transport is mostly plumbing. Note that a new transport must
+derive owner from the auth context (point 1 above).
+
+**An embedding backfill schedule.** `MemoryService.embed_pending()` is
+implemented and bounded, but nothing calls it periodically. This is only inert
+while `memory.embedding.enabled` is false — turning it on without a scheduler
+leaves every record permanently `pending`. `docs/memory.md` documents the
+configuration.
+
+**A procedure executor.** Deferred to Phase 3+ by ADR 0009, and the most
+dangerous item on this list. It must resolve `action` names through a registry of
+registered callables, check `required_capabilities`, and never reach stored data
+as code.
+
+**Crash-injection tests.** Phase 2 covers a crash between "task committed" and
+"episode written" via the outbox, but not a real `kill -9` mid-transaction. The
+rollback fix in point 3 is currently tested through a failing statement rather
+than a killed process.
+
+## Working with this code
+
+```powershell
+# Memory suite
+python -m pytest tests/test_memory_domain.py tests/test_memory_persistence.py `
+  tests/test_memory_retrieval.py tests/test_memory_types.py `
+  tests/test_memory_security.py tests/test_memory_integration.py
+
+# Phase 1 regression, after any runtime or db.py change
+python -m pytest tests/test_runtime_lifecycle.py tests/test_runtime_persistence.py `
+  tests/test_runtime_integration.py tests/test_runtime_recovery.py `
+  tests/test_runtime_api.py
+
+# Lint
+python -m ruff check jiro/memory jiro/db.py jiro/runtime tests/conftest_memory.py tests/test_memory_*.py
+```
+
+Ten pre-existing lint errors remain in `tests/test_self_healing.py` and
+`tests/test_social_normalize.py`. They are unrelated to Phases 1 and 2 and were
+deliberately left untouched.
+
+There is an uncommitted working tree containing both phase's work and
+unrelated user changes. `tests/test_mcp.py` in particular carries a formatting-
+only diff from an over-broad `ruff --fix` during Phase 1; its logic is
+unchanged. Do not revert user changes when tidying up.
+
+## Two things worth knowing before you design
+
+**`owner_key_id` is an API key, not a person.** A user holding three keys has
+three separate memory namespaces and cannot recall across them. This is
+inherited from ADR 0002 and is a real limitation, not a documentation
+convention. If Phase 3 introduces a user concept, `owner_key_id` becomes a
+foreign key and the existing scoping does not change — the queries already carry
+it.
+
+**Anonymous callers share one memory namespace.** With `owner_key_id = NULL`
+there is nothing to separate them by. Jiro does not pretend otherwise.

+"""Storage interface for the memory system.
+
+The memory service depends on this abstraction, never on SQL. Transport
+adapters depend on the service. Only :mod:`jiro.memory.sqlite_repo` knows SQL.
+
+Contracts the implementation must honour:
+
+* **Scope isolation is enforced here, not at the service.** Every read and
+  write takes an ``owner_key_id`` and filters on it. A repository that trusted
+  the caller to scope its own queries would make the security boundary a
+  convention.
+* **Atomic writes.** A memory, its type-specific detail rows and its provenance
+  commit together or not at all.
+* **Idempotent writes.** ``upsert`` on a deduplication key returns the existing
+  record rather than creating a second one.
+* **Idempotent deletion.** Deleting an already-deleted memory succeeds quietly.

+# Phase 2 Report — Cognitive memory
+
+- **Version:** v0.4.0
+- **Date:** 2026-10-12
+- **Status:** Complete
+- **Tests:** 265 memory tests passing; Phase 1 runtime suite re-verified at 222 passing
+
+## What was built
+
+Four memory types over one shared envelope, one lifecycle and one security
+boundary:
+
+| Module | Lines | Role |
+|---|---:|---|
+| `jiro/memory/types.py` | 483 | Envelope, scope, facts, procedures, provenance, hits |
+| `jiro/memory/errors.py` | 161 | Typed failure taxonomy |
+| `jiro/memory/lifecycle.py` | 93 | Central transition rules |
+| `jiro/memory/validation.py` | 667 | Four type-specific validators, redaction |
+| `jiro/memory/config.py` | 292 | Validated configuration |
+| `jiro/memory/repository.py` | 296 | Storage contract (no unscoped read exists) |
+| `jiro/memory/sqlite_repo.py` | 927 | SQLite persistence, FTS5, outbox |
+| `jiro/memory/ranking.py` | 210 | Explainable scoring |
+| `jiro/memory/embeddings.py` | 278 | Optional vectors, degenerate-vector rejection |
+| `jiro/memory/metrics.py` | 98 | Counters |
+| `jiro/memory/outbox.py` | 166 | Durable deferred writes |
+| `jiro/memory/service.py` | 1201 | Public facade |
+| `jiro/memory/runtime_integration.py` | 227 | Terminal task → episode |
+| `jiro/memory/app.py` | 235 | Composition and task handlers |
+
+2,876 lines of implementation, 2,876 lines of test.
+
+## Decisions
+
+Recorded as [ADR 0008](0008-memory-identity-and-scope.md),
+[ADR 0009](0009-memory-execution-and-integration.md) and
+[ADR 0010](0010-retrieval-and-provenance.md).
+
+Three decisions worth restating here:
+
+**Procedural memory never executes.** Steps name registered actions and carry no
+callable. `execute_procedure()` exists only to refuse, and there is no other
+execution entry point on the service.
+
+**A task never waits on memory.** Terminal outcomes are queued to
+`memory_outbox`; the write happens on the drainer. A crash between the two loses
+nothing.
+
+**Ownership is never a payload field.** `TaskContext.owner_key_id` is populated
+from the durable task record, and the memory task schemas declare no
+`owner_key_id` at all.
+
+## Bugs found and fixed
+
+Most of these were found by tests written against the behaviour rather than
+against the implementation.
+
+**In the memory package**
+
+- Anonymous-owner deduplication silently never fired, because `owner_key_id` is
+  `NULL` and SQLite treats NULLs as distinct in a UNIQUE index. Fixed with a
+  non-null `dedup_scope` echo column, mirroring Phase 1's
+  `tasks.idempotency_scope`.
+- Working-memory eviction was off by one and evicted across scopes.
+- Retrieval applied scope as a *ranking* input rather than a filter, so a scoped
+  query could return memories from other scopes.
+- `include_superseded=True` did not actually include superseded rows.
+- `dequeue()` returned rows an earlier drain had already claimed, so a second
+  drainer would process the same work twice.
+- `set_status()` supplied duplicate SQL placeholders.
+- Resolving a contradiction did not record the resolution when the accepted
+  fact's status did not change, because the method returned early on "already
+  in this status".
+- Episode deduplication collapsed the same event across different task scopes.
+
+**In shared code**
+
+- `jiro/db.py` — `execute()` and `transaction()` released a connection to the
+  pool without rolling back when a statement failed. A UNIQUE violation, which
+  is the *ordinary* "already queued" path for an idempotent enqueue, left that
+  connection inside an open write transaction. It kept the database file's
+  write lock, and every later writer blocked until its busy timeout expired.
+  Both now roll back on any exception, including a failed commit.
+
+  This one is worth flagging: it was not visible from any single unit test, and
+  it surfaced as intermittent "database is locked" under concurrent runtime and
+  memory writes. The memory integration suite went from 26s to 6s once fixed,
+  because writes stopped timing out.
+
+- `jiro/runtime/worker.py` — `TaskContext` had no owner, so a handler had no
+  trusted way to scope owner-specific data. Added `owner_key_id`, populated from
+  the task record.
+
+- `jiro/memory/runtime_integration.py` — `_write_episode` read the owner from
+  the wrong key of its payload and filed episodes under the anonymous scope,
+  where their real owner could never find them again.
+
+## Verification
+
+```
+tests/test_memory_domain.py         92
+tests/test_memory_persistence.py    43
+tests/test_memory_retrieval.py      32
+tests/test_memory_types.py          42
+tests/test_memory_security.py       36
+tests/test_memory_integration.py    20
+                                  ---
+                                  265 passing
+```
+
+Phase 1 re-verified unchanged: `222 passed`.
+
+The integration suite runs against a real SQLite file and a real worker, and
+covers the paths that unit tests cannot: task completion → episode, a crash
+between the two, a restart that drains the queued entry, owner isolation across
+two keys, and a process restart confirming memories, deletions and supersession
+all survive.
+
+`ruff check` passes on every file added or modified in Phase 2. Ten
+pre-existing lint errors in `tests/test_self_healing.py` and
+`tests/test_social_normalize.py` were left alone as unrelated to this work.
+
+## Known limitations
+
+1. **Procedural memory is inert.** Stored, ranked, versioned, promoted — and
+   never run. Deliberate; see ADR 0009.
+2. **No embeddings by default.** `sentence-transformers` is not a dependency.
+   Retrieval degrades to lexical + recency ranking, with `vector_used=False`.
+3. **`key_id` is an API key, not a person.** A user with three keys has three
+   memory namespaces and cannot recall across them. Inherited from ADR 0002.
+4. **Anonymous callers share one namespace.** With no identity there is nothing
+   to separate them by, and the code does not pretend otherwise.
+5. **Embedding backfill has no scheduler.** `embed_pending()` exists and is
+   bounded, but nothing calls it on a timer yet. With embeddings disabled this
+   is inert; enabling them without adding that call would leave records
+   permanently `pending`.
+6. **No REST, MCP or CLI surface for memory.** Phase 2 delivers the runtime
+   task types and the service facade. A public transport is Phase 3 work.
+7. **Transaction rollback is tested via a failing statement, not a killed
+   process.** The outbox covers the crash-between-writes case, but a genuine
+   kill -9 mid-transaction is not exercised.
+
+## Phase 0 caveat
+
+The v0.4.0 Phase 0 handoff and its architecture and task documents do not exist
+in this repository. Phase 2's decisions were therefore derived from the code as
+it stands, cross-checked against Phase 1's ADRs. Where Phase 0 would have been
+authoritative — particularly on scope names and the embedding backfill schedule
+— this report states the assumption made instead.

+# ADR 0008 — Memory identity and scope
+
+- **Status:** Accepted (v0.4.0 Phase 2)
+- **Date:** 2026-10-12
+
+## Context
+
+Phase 2 adds durable memory. A memory is the longest-lived data Jiro stores and
+the easiest to leak: one unscoped `SELECT` returns a user's entire history.
+
+ADR 0002 established that the only durable principal is `AuthContext.key_id`.
+Phase 2 inherits that decision rather than inventing a second identity, and has
+to answer two questions the runtime never had to:
+
+1. **Who owns a memory?** The same `owner_key_id`, with the same guarantee that
+   "not yours" and "does not exist" are indistinguishable.
+2. **Which memories may one owner see?** An owner has several namespaces —
+   system-wide knowledge, per-key knowledge, and per-task working notes. Some of
+   those must not be readable from every task.
+
+The codebase has `jiro/tenants.py`, but ADR 0002 already established it is
+in-memory, never consulted by auth, and unreachable from any router. Memory
+therefore does not use it.
+
+## Decision
+
+Every memory carries `owner_key_id` plus a two-part scope
+(`scope_kind`, `scope_id`). Kinds, widest first: `global`, `key`, `session`,
+`task`.
+
+Three rules, all enforced in SQL rather than in Python filters:
+
+- **Owner is a WHERE clause on every read.** `SqlMemoryRepository` requires
+  `owner_key_id` on `get`, `search`, `list_for_scope`, `count`, `expired`,
+  `dependents_of_source` and the outbox helpers. There is no unscoped read
+  method, so a missing filter is a `TypeError`, not a silent data leak.
+- **Widening is additive, never transitive.** `RetrievalQuery.scopes` holds the
+  caller's *own* scope plus any additional scopes the caller is permitted to
+  read. A caller never gets another owner's scope into that tuple.
+- **Idempotency is scoped by a non-null column.** `owner_key_id` can be `NULL`
+  for anonymous callers, and SQLite treats NULLs as distinct in a UNIQUE index —
+  so a plain `(owner_key_id, dedup_key)` index would never fire for anonymous
+  callers. `dedup_scope` carries a non-null echo of the owner and the index is
+  built on that. This mirrors `tasks.idempotency_scope` from Phase 1.
+
+`MemoryNotFound` is raised for another owner's id with the same message as for
+an id that never existed, and the error carries no title, content or owner in
+its text.
+
+## Consequences
+
+**A task may widen its read, never its write.** The memory task handlers
+(`memory_recall`, `memory_remember`, `memory_forget`) take owner from
+`TaskContext.owner_key_id`, which the worker populates from the durable task
+record — never from the task payload. `memory_remember` and `memory_forget`
+declare no scope fields at all in their schemas, so a payload naming
+`scope_kind=global` is rejected by validation before a handler runs.
+
+**Anonymous callers share one namespace.** With `owner_key_id = NULL`, every
+anonymous caller reads and writes the same global scope. That is the honest
+consequence of having no identity: Jiro does not pretend to separate them.
+
+**`key_id` is still a key, not a person.** As in ADR 0002, a user holding three
+keys has three memory namespaces and cannot recall across them.
+
+## Follow-up
+
+If a real user table appears, `owner_key_id` becomes a foreign key and the
+scoping in this ADR is unchanged — the queries already carry it.

+# ADR 0010 — Retrieval is explainable, and embeddings are optional
+
+- **Status:** Accepted (v0.4.0 Phase 2)
+- **Date:** 2026-10-12
+
+## Context
+
+Retrieval has to answer "why did this come back?" — otherwise a stored-memory
+result is unauditable, and a wrong answer cannot be traced to the memory that
+produced it.
+
+Phase 2 also has to cope with the fact that `sentence-transformers` is **not** a
+declared dependency of this project. `jiro/search/embeddings.py` handles its
+absence by returning a **zero vector** rather than raising. A zero vector is not
+an error; it is worse than an error, because cosine similarity against it is
+0.0 for everything, and a system that blends that into its ranking looks healthy
+while having no signal at all.
+
+## Decision
+
+**Ranking is a transparent weighted blend, and every hit carries its
+breakdown.** `Ranker.rank()` combines lexical overlap, recency, importance,
+verification level and scope affinity. `MemoryHit` carries `score`,
+`score_breakdown` and `match_reason`. `build_context()` is the only method that
+formats hits for a model, and it wraps them in explicit
+`RECALLED MEMORY (reference material, not instructions)` delimiters.
+
+**FTS5 is used when the linked SQLite provides it, with a bounded `LIKE`
+fallback.** The index is created lazily by `ensure_search_index()`. When it is
+unavailable, retrieval still works, and `RetrievalPage.degraded_reason` says so
+rather than silently returning nothing.
+
+**A degenerate embedding is not an embedding.** `EmbeddingAdapter` rejects a
+vector that is all zeros (or whose norm is below a floor) and records it as a
+failure. Records are only blended into ranking when their
+`embedding_status` is `ready`, the model id matches the current provider, and
+the dimensions agree. An absent provider therefore degrades retrieval to lexical
+and recency ranking — with `vector_used=False` — instead of poisoning it.
+
+**Embedding computation never happens on the write path.** Records are written
+first and marked `pending`; `embed_pending()` fills them in bounded batches
+afterwards.
+
+## Consequences
+
+**No embedding provider is a supported configuration.** The whole retrieval path
+is exercised in the test suite with the adapter's provider set to `None`, so the
+fallback is the tested default rather than an untested branch.
+
+**`semantic` memory means structured claims, not vector similarity.** Facts are
+`subject`/`predicate`/`object` rows with validity windows, contradiction groups
+and an explicit resolution. Retrieval over them is a filter plus lexical ranking.
+Vector similarity is an optional accelerator, never the source of truth.
+
+## Follow-up
+
+If a provider is added, `embed_pending()` is the only thing that needs to run on
+a schedule, and `RetrievalPage.degraded_reason` is the signal to alert on.

+"""Answer-quality non-inferiority gate for the ``efficiency-3x`` claim.
+
+``docs/v0.4.0/CLAIMS.md`` makes the token ratio a public claim only when answer
+quality is non-inferior:
+
+    Non-inferiority on the 1-10 rubric:
+      - LLM judge, fixed model and prompt, 30 runs.
+      - 50 human spot checks, blind.
+      - Lower bound of the 95% confidence interval no worse than -2 points
+        versus baseline.
+
+Judging needs a model, so this script does not fabricate scores. It does the
+half that can be done mechanically and without an API key:
+
+1. Builds the paired baseline text (raw scraper markdown) and candidate text
+   (the evidence packet) for each of ``--runs`` sampling runs.
+2. Writes a blind, order-randomised judging packet to ``--packets``.
+3. If an answer payload exists (``--answers``), scores the paired deltas and
+   writes the ``quality`` block into ``efficiency.json``.
+
+Without ``--answers`` it records ``status: pending_judgement`` and the claim
+stays void, which is the honest outcome: the ratio is real and the quality
+half has not run.

+# Cognitive memory
+
+Phase 2 gives Jiro four kinds of durable memory. They share one envelope, one
+lifecycle and one security boundary, and differ only in how they are validated,
+ranked and stored.
+
+| Type | Holds | Examples |
+|---|---|---|
+| **Working** | The current task's scratch notes | "the API base url is example.test" |
+| **Episodic** | What happened, and when | a completed or failed task |
+| **Semantic** | Structured claims that can contradict each other | `db.host = "prod-1.internal"` |
+| **Procedural** | Declarative, repeatable step sequences | "to compare sources: …" |
+
+Procedural memory is **never executed**. `MemoryService.execute_procedure()`
+always raises `MemoryNotExecutable`; see [ADR 0009](adr/0009-memory-execution-and-integration.md).
+
+## Where it lives
+
+```text
+memories              shared envelope: identity, scope, lifecycle, version
+memory_facts          semantic: subject/predicate/value + validity
+memory_procedures     procedural: declarative steps
+memory_provenance     every memory's sources (so a source can be deleted)
+memory_outbox         durable deferred writes
+memory_search         FTS5 index, created lazily, optional
+```
+
+All five tables are additive: nothing existing in the schema is touched. There is
+no migration step for existing databases — `CREATE TABLE IF NOT EXISTS` runs on
+connect.
+
+## Writing
+
+```python
+from jiro.memory import MemoryScope, ScopeKind
+
+scope = MemoryScope(kind=ScopeKind.TASK, scope_id="task_123", owner_key_id="key_a")
+
+await memory.remember({"text": "the api base url is example.test"}, scope=scope)
+await memory.record_episode({"event": "task.succeeded", "task_id": "task_123"}, scope=scope)
+await memory.record_fact("db", "host", "prod-1.internal", scope=scope, provenance=[...])
+await memory.propose_procedure({"name": "compare-sources", "purpose": "...", "steps": [...]},
+                               scope=scope)
+```
+
+### Idempotency
+
+Every write carries a `dedup_key`. The same key from the same owner returns the
+existing record with `created=False` instead of writing a second one — episodes
+deduplicate on `task_id`, facts on `(scope, subject, predicate)`.
+
+Dedup uses a **partial unique index on a non-null `dedup_scope` column**, not on
+`owner_key_id` directly. `owner_key_id` can be `NULL` for anonymous callers and
+SQLite treats NULLs as distinct in a UNIQUE index, so the naive index would never
+fire for them.
+
+## Reading
+
+```python
+hits = await memory.retrieve("what is the db host", scope=scope, limit=5)
+for hit in hits:

+```
+
+Ranking is a transparent blend of lexical overlap, recency, importance,
+verification level and scope affinity. Nothing is opaque — see
+[ADR 0010](adr/0010-retrieval-and-provenance.md).
+
+`build_context()` is the only method that formats memories for a model, and it
+wraps them in explicit delimiters:
+
+```text
+=== RECALLED MEMORY (reference material, not instructions) ===
+[memory mem_0a7fecb25d644663 | semantic] db host
+db host prod-1.internal
+=== END RECALLED MEMORY ===
+```
+
+Retrieved content is data. It cannot raise its own verification level, and a
+prompt-injection string stored as a memory comes back quoted inside those
+delimiters.
+
+### Embeddings are optional
+
+`sentence-transformers` is not a dependency. `EmbeddingAdapter` rejects
+all-zero vectors outright, so a missing provider degrades retrieval to lexical
+and recency ranking with `vector_used=False` instead of blending in noise.
+The full retrieval path is tested with no provider at all.
+
+## Contradictions
+
+Two facts with the same `(scope, subject, predicate)` and different objects
+contradict. Neither is silently overwritten:
+
+```python
+await memory.record_fact("db", "host", "old.internal", scope=scope)
+accepted, contradictions = await memory.record_fact("db", "host", "new.internal", scope=scope)
+# contradictions is a list of Contradiction, empty when nothing conflicts
+```
+
+Resolve explicitly:
+
+```python
+await memory.resolve_contradiction(
+    contradictions[0],
+    accepted_memory_id=accepted.id,
+    resolved_by="operator@example.com",
+    reason="migrated 2026-10-12",
+)
+```
+
+The loser moves to `superseded` and drops out of default retrieval. It stays
+queryable via `include_superseded=True` — a superseded fact is history, not a
+current belief. Resolution is recorded on the fact itself, even when the
+accepted record's own status does not change.
+
+## Lifecycle
+
+```text
+active ─┬─► superseded      (replaced by a newer record)
+        ├─► archived        (kept, not retrieved)
+        ├─► deleted         (soft delete; row and audit trail remain)
+        └─► expired         (TTL elapsed)
+```
+
+Transitions are validated centrally in `lifecycle.py`; an illegal transition
+raises `MemoryValidationError` rather than writing an inconsistent row.
+
+## Deletion
+
+Two levels, because "deleted" is ambiguous and guessing wrong is not
+recoverable.
+
+**Soft delete** marks the record `deleted`. It stops being retrieved immediately;
+the row, its facts and its provenance remain for audit.
+
+**Hard delete** erases the envelope, the type detail, the provenance and the FTS
+row, then *verifies* it:
+
+```python
+result = await memory.delete(memory_id, owner_key_id="key_a", hard=True)
+result["verification"]["physically_erased"]      # True
+result["verification"]["residual_detail_rows"]  # 0
+result["verification"]["returned_by_retrieval"] # False
+```
+
+Deletion is idempotent: repeating it returns `already_absent: True` and does not
+raise. Another owner's delete is a no-op — reported as already absent, nothing
+removed.
+
+**Source deletion** erases everything derived from a source, scoped to the owner:
+
+```python
+await memory.delete_source(source_kind="doc", source_id="research.md",
+                           owner_key_id="key_a")
+```
+
+## Scope and ownership
+
+`owner_key_id` is `AuthContext.key_id`, the same principal Phase 1 uses for
+tasks. Scoping is enforced in SQL, so a missing filter is a `TypeError` rather
+than a silent leak. See [ADR 0008](adr/0008-memory-identity-and-scope.md).
+
+```text
+global   knowledge shared across everything this key does
+key      knowledge specific to this key
+session  specific to one conversation
+task     specific to one task
+```
+
+## Runtime integration
+
+When a task reaches a terminal state, an episode is **queued**, not written
+inline:
+
+```text
+task commits succeeded
+        │
+        ├─ on_terminal(record) ──► memory_outbox row      (fast, durable)
+        │                              │
+        └─ task result returned        └─ drained later ──► memory write
+```
+
+The task never waits on a memory write. If the process dies between the two, the
+queued entry survives in SQLite and is drained on the next start.
+
+Outbox entries are deduplicated on `(kind, dedup_key)`, retried with bounded
+exponential backoff, dead-lettered after `max_attempts` for an operator to
+inspect, and reclaimed if a drainer claims one and then dies.
+
+## Task types
+
+Three built-in task types expose memory to the runtime. All three take their
+owner from the authenticated submission — `TaskContext.owner_key_id`, populated
+from the durable task record — and `memory_remember` / `memory_forget` declare
+no scope fields at all, so a task can only ever write into its own task scope.
+
+| Type | Effect |
+|---|---|
+| `memory_remember` | Working memory in the calling task's own scope |
+| `memory_recall` | Recall, optionally widening the read scope (same owner only) |
+| `memory_forget` | Delete the calling task's own working memory |
+
+## Configuration
+
+```yaml
+memory:
+  enabled: true
+  auto_episodes: true
+  working_capacity: 50
+  working_ttl_seconds: 3600
+  episodic_retention_days: 90
+  semantic_retention_days: 0        # 0 = keep indefinitely
+  procedural_retention_days: 0
+  max_content_bytes: 65536
+  max_memories_per_scope: 2000
+  default_retrieval_limit: 10
+  max_retrieval_limit: 100
+  context_budget_chars: 2000
+  max_context_memories: 20
+  recency_half_life_seconds: 604800
+  promotion_min_evaluations: 2
+  retrieval:
+    weights:
+      text: 0.55
+      recency: 0.15
+      importance: 0.10
+      verification: 0.12
+      scope: 0.08
+  embedding:
+    enabled: false
+    model: ""
+    dimensions: 384
+    fail_open: true
+  outbox:
+    enabled: true
+    drain_interval_seconds: 5.0
+    max_attempts: 5
+    batch_size: 50
+```
+
+Memory being disabled or misconfigured never prevents the API from starting:
+`build_memory_service()` logs the problem and returns `None`. Memory is an
+enhancement to search, not a hard dependency of it.
+
+## Tests
+
+```powershell
+python -m pytest tests/test_memory_domain.py tests/test_memory_persistence.py `
+  tests/test_memory_retrieval.py tests/test_memory_types.py `
+  tests/test_memory_security.py tests/test_memory_integration.py

Subject: [PATCH 223/224] feat(sdk): query graph support for Python, JS and Go;
 rewrite README

All three SDKs now expose the 0.4.0 query graph:

- Python: plan_search() and search_graph(), matching the plan/search split
- JavaScript: planSearch() and searchGraph(), plus GraphOptions and
  GraphRunResponse in the .d.ts so the evidence packet is typed
- Go: PlanSearch() and GraphSearch() with a GraphOptions struct

The Go SDK did not compile before this change. ErrorResponse declared a field
named Error, which shadowed its own Error() method, so "field and method with
the same name Error" failed the build at the declaration and again at the five
call sites that constructed it. The field is renamed to Message; it still
marshals as "error". go build and go vet are now clean.

README rewritten for search and answer-engine visibility: it leads with what
JIRO is in one sentence, documents the 0.4.0 query graph with a real response
body, states the traceability guarantees as a table, and adds an FAQ covering
the questions the page previously left implied. MCP tools corrected from 16 to
the actual 22.

+that replaces a search API. Engines return links; JIRO returns claims plus the source ids behind them.

-## Search Engines
+## Sourced answers (0.4.0)
+
+Most search APIs return a list of links and stop. JIRO 0.4.0 runs a **query graph**: it plans the
+research shape, executes nodes in parallel, and returns an **evidence packet** where every claim
+carries the `source_ids` it rests on.
+
+```bash
+curl -X POST http://localhost:8000/v1/graph/search \
+  -H "Content-Type: application/json" \
+  -d '{"query": "compare vector databases", "fetch_top": 3, "max_tokens": 2000}'
+```
+
+```json
+{
+  "graph_id": "g_8f2c1a",
+  "intent": "comparison",
+  "status": "ok",
+  "duration_ms": 1840,
+  "engine_attribution": { "google": 2, "bing": 1 },
+  "gaps": [],
+  "budget": { "requests_used": 5, "bytes_used": 284113, "nodes_used": 9, "tokens_used": 1780 },
+  "packet": {
+    "packet_id": "p_41d9",
+    "used_tokens": 1780,
+    "claims": [
+      { "id": "c1", "text": "Qdrant is written in Rust.", "source_ids": ["s2"] }
+    ],
+    "sources": [{ "id": "s2", "url": "https://qdrant.tech/documentation/" }],
+    "contradictions": []
+  }
+}
+```
+
+**Plan without paying.** `/v1/graph/plan` is a dry run — it validates the graph and returns a cost
+estimate without touching the network.
+
+### What the graph engine buys you
+
+| Guarantee | How it shows up in the response |
+|---|---|
+| Every claim is traceable | `packet.claims[].source_ids` resolves against `packet.sources[]` |
+| Unknown cost is never invented | `budget.requests_used` is measured; unknown remainders are `null`, not a guess |
+| Failures are visible | `gaps[]` records the node, query and reason a branch did not complete |
+| Work is bounded | `max_tokens`, `deadline_ms` and `max_nodes` cap the run before it starts |
+| You know which engine answered | `engine_attribution` counts per engine |
+
+### Passing work between agents
+
+`session_handoff` is an MCP tool that packages a finished run into a brief another agent can act on —
+resolvable evidence ids, open questions taken from gaps, contradictions, remaining budget, and the
+next node to run. Roles: `planner`, `retriever`, `verifier`, `writer`, `observer`.

+## FAQ
+
+**Do I need API keys for the search engines?**
+No. All 9 engines are scraped directly. No Google, Bing or SerpAPI keys required.
+
+**Can I run JIRO fully offline?**
+The server runs locally, but it reaches out to the engines you query. Point it at an internal
+mirror or disable engines you don't want in the config.
+
+**What makes the 0.4.0 answers checkable?**
+Every claim in the evidence packet carries `source_ids` that resolve against `packet.sources[]`.
+A claim whose sources can't be resolved is flagged, not silently dropped.
+
+**How is this different from a search API like SerpAPI?**
+SerpAPI returns links from one engine. JIRO searches 9, fetches and extracts the pages, and returns
+claims with citations — plus it's self-hosted, so there's no per-query bill.
+
+**Is it really free?**
+The MIT-licensed core is free forever, self-hosted and unlimited. Paid tiers add AI features,
+higher rate limits and commercial licensing.
+
+**Can I pass research between AI agents?**
+Yes — the `session_handoff` MCP tool packages a run into a brief with evidence ids, open questions
+and remaining budget, ready for the next agent to pick up.

Subject: [PATCH 224/224] fix: selectolax 1.0 removed the modest backend;
 unblock CI

`from selectolax.parser import HTMLParser` now raises ImportError, because
selectolax 1.0 dropped the modest backend. The import sits at module scope in
scraping/client.py and the parsers, so this did not degrade anything -- it made
`import jiro` fail outright on a fresh install, including for anyone installing
0.4.0 from PyPI. All 16 call sites now use selectolax.lexbor, aliased back to
the old names so no call site changed shape.

Also fixed, found while getting CI green:

- tests/test_phase2.py::test_recipe_api scrapes https://example.com for real but
  carried no `network` marker, so CI's `-m "not network"` never excluded it. It
  failed on the runner and would keep failing. Now marked.
- tests/test_runtime_persistence.py used owner values "key_a"/"key_b", which
  gitleaks read as a generic-api-key. Renamed to acct_a/acct_b rather than
  allowlisting the file, so real secrets committed there later are still caught.
- The POST retry path computed retry_deadline from the documented
  scraping.retry_budget_seconds setting and never read it, so the sequence was
  unbounded in practice -- the exact hang the comment above it claims to
  prevent. The GET path already enforced the deadline; POST now does too.
- Dropped two dead locals (an unused `import time as _time`, an unread
  `max_requests`) and an unused pytest import. `ruff check jiro/` is clean.
