As of Sprint 5, the runtime direction is +**llama.cpp (`llama-server`)**, not vLLM/TensorRT-LLM — see +`docs/architecture_v2_family_of_models.md` Section 6. `compose.yaml` (the +trtllm setup) stays in this directory as historical reference until Drew +retires it; do not use it for new deployments. + +## Two ways to run the runtime + +**A. Model manager spawns llama-server natively (V1 default).** +`nodes/model_manager_4090` (`manager.py`) owns weights tiering, the +llama-server process lifecycle, and presence reporting to the hub. It calls +`llama-server` as a plain subprocess with the flags below — no Docker +involved. This is the default because the manager needs direct control over +staging weights onto the hot tier (`ensure_hot()`) before each spawn, and +needs to poll `/health` and manage SIGTERM/SIGKILL directly. Use this path +whenever the model manager service is running. + +**B. `compose.llamacpp.yaml` (standalone / manual bring-up).** +Use this compose file when you need to run llama-server by hand — the model +manager isn't running, you're debugging a GGUF outside the manager's +lifecycle, or you want a quick manual smoke test. It runs the official CUDA +server image (`ghcr.io/ggml-org/llama.cpp:server-cuda`), mounts the hot tier +at `/models`, and passes the same flags the manager would pass for family +member #1 ("vera"). It does **not** do tiering or presence reporting — those +only happen when the manager is in the loop (path A). + +## Model manager environment variables + +The manager reads settings via `MODELMGR_`-prefixed env vars +(`nodes/model_manager_4090/config.py`): + +| Variable | Purpose | +|---|---| +| `MODELMGR_HOT_DIR` | Hot tier path (2 TB Gen4 NVMe) — active/loadable weights. | +| `MODELMGR_WARM_DIR` | Warm tier path (1 TB Gen2 NVMe) — occasional members. | +| `MODELMGR_COLD_DIR` | Cold tier path (6 TB HDD/NAS) — archive. | +| `MODELMGR_HUB_URL` | Hub base URL the manager reports presence to. | +| `MODELMGR_HUB_TOKEN` | Bearer token for the hub's presence endpoint. | +| `MODELMGR_LLAMA_SERVER_BIN` | Path/name of the `llama-server` binary the manager spawns. | + +## Weights filename convention + +`weights_filename()` in `nodes/model_manager_4090/manager.py` builds the +on-disk filename as `..`, where the source +tail is the last path segment of `model.source` from `family/registry.yaml`. + +For family member #1 ("vera": `hf:Qwen/Qwen3-30B-A3B-Instruct-2507`, quant +`Q4_K_M`, format `gguf`), the exact expected filename is: + +``` +Qwen3-30B-A3B-Instruct-2507.Q4_K_M.gguf +``` + +Download tooling, the hot/warm/cold tier directories, and both runtime paths +above (A and B) must all agree on this name. + +## Why tiering exists: don't mmap off the cold tier + +`llama.cpp` does not tier weights for us — `mmap` will happily page a GGUF +straight off the HDD/cold tier, and it works, but page-in latency makes +inference miserable. That's the exact failure mode +`nodes/model_manager_4090`'s tiering (`ensure_hot()`) exists to avoid: it +stages weights onto the hot NVMe tier *before* starting llama-server, so the +model only ever loads/mmaps from fast storage.

This is the default write target for every turn. Only that member's queries can read it. +- **`shared:household`** — the family's common ground: sensor events (Jetson classification, born shared) and conversation memories a person has explicitly promoted. Every member's queries can read it. +- **`experiential:`** — reserved for Project Vector (a member's own sensor platform). No writers in V1; only that member's queries can read it. + +`nodes/embedder_4070/scopes.py` is the single source of truth for these rules (pure functions, no Chroma dependency, so the privacy logic is unit-testable on its own). + +### Provenance metadata + +Every chunk's metadata gained four fields on top of the Sprint 2 schema (`session_id`, `turn_idx`, `ts`, `model_used`, etc. — all unchanged): + +- `scope` — one of the three scopes above. +- `member_id` — the member the row belongs to (`"household"` for `shared:household` rows). +- `origin` — `conversation | sensor | promotion | vector_platform | delegated_task` (the last two are reserved for Project Vector and the V1.5 concierge; no writer produces them yet). +- `participants` — who was in the conversation, from `token_name` attribution. Chroma metadata values must be scalars, so this is stored **comma-joined** (e.g. `"drew"` or `"drew,vera"`), not as a list. + +Promoted rows carry three additional fields: `promoted_from` (the source row id), `promoted_from_member` (which member's private scope it came from), and `promoted_by` (who confirmed the share). + +### `/memory/write` requires scope + member_id + +`POST /memory/write` on the embedder now takes mandatory `scope` and `member_id` fields (`origin` defaults to `"conversation"`, `participants` defaults to empty). The service validates before writing: a member may only write into its own `private:` / `experiential:` scopes or into `shared:household` — never into another member's scopes. A cross-member write attempt is rejected with `400` before anything touches Chroma. There is no longer a way to write an unscoped row. + +### `/memory/query` is server-side scope-filtered — always + +`POST /memory/query` now takes a mandatory `member_id`. The embedder builds the Chroma `where` clause from it unconditionally: + +``` +scope IN (private:, shared:household, experiential:) +``` + +Callers cannot widen this — there is no parameter that requests a different or broader scope set, and the filter is applied inside the embedder service, not trusted to the brainstem or the model. This **amends the Sprint 2 decision** documented above (Chunk B: "no default session filter, because the done-criterion is cross-session recall"). That done-criterion is preserved — a member still recalls every past session it has had — but it no longer means *every session of every member*. Cross-session recall within a member survives; cross-member recall is now structurally impossible through this API. `session_id_filter` and `exclude_parent_turn_id` remain available as optional refinements *inside* the member's visible scopes, not as ways around them. + +### `/memory/promote` — copy, never move + +`POST /memory/promote` (`member_id`, `memory_id`, `promoted_by`) shares a private memory with the household without touching the original: + +- The shared copy gets a **deterministic id** — `{source_id}::promoted` — so promoting the same row twice is a no-op (`already_promoted: true` in the response) rather than a duplicate. +- The copy is written to `shared:household` with the full paper trail: `origin: "promotion"`, `promoted_from`, `promoted_from_member`, `promoted_by`. The private original's metadata and scope are untouched. +- The source row must actually be in `private:` for that member — promoting a row that isn't yours (or isn't private) is rejected with `400`. +- At the hub, `POST /members/{id}/memory/promote` is the person's confirmation step; reaching that endpoint at all establishes consent (only people hold bearer tokens), per the offer-then-confirm rule in the V2 decision record — a member may *offer* to share in conversation, but the write only happens once the person calls this endpoint. + +### Migration: `scripts/migrate_memory_scopes.py` + +Pre-Sprint-5 rows have no `scope` metadata, which makes them invisible to the now-mandatory filter above. The migration script backfills exactly those rows: + +- **Dry-run by default.** `python scripts/migrate_memory_scopes.py` only prints the reconciliation plan (`total` / `already_scoped` / `would update`); nothing is written until you pass `--apply`. +- **Grandfathers into member #1's private scope.** Unscoped rows get `scope=private:` (default: the first entry in `family/registry.yaml`), `member_id=`, `origin=conversation`, and `participants` from the (optional) `--participants` flag — pre-V2 rows never recorded who spoke, so this defaults to empty. +- **Idempotent.** Rows that already carry a `scope` are left untouched, so re-running the script (with or without `--apply`) is always safe. +- **Reconciles to the row.** The script tallies `already_scoped + updated` against the collection's total count and exits nonzero if anything is unaccounted for, rather than silently leaving rows behind. +- Runs inside the embedder container, since that's what owns the Chroma volume: `docker compose exec embedder python scripts/migrate_memory_scopes.py [--apply] [--member ID] [--participants a,b] [--persist-dir ...] [--collection ...]`. diff --git a/docs/sprints/SPRINT_5_BENCH_PREREG_2026-07-25.md b/docs/sprints/SPRINT_5_BENCH_PREREG_2026-07-25.md new file mode 100644 index 0000000..3f5d290 --- /dev/null +++ b/docs/sprints/SPRINT_5_BENCH_PREREG_2026-07-25.md @@ -0,0 +1,49 @@ +# Sprint 5 bench pre-registration — member #1 baseline (Card 7) + +**Date registered:** 2026-07-25 (before any llama.cpp run on the 4090) +**Discipline:** same as Sprint 3d — win conditions declared here, before +the first measured run; bootstrap CIs on latency stats; no retroactive +goalpost moves.
