What this is: the flagship, most-complete Hanzo SDK — a uv workspace of 65
packages: the typed cloud client (hanzoai), agents, MCP server + tools, memory,
distributed compute, and the hanzo CLI. pip install hanzo.
Canonical role (one-way SDK model): Hanzo ships two SDK lines per language —
(1) the full cloud SDK generated from OpenAPI, (2) the AI/agents library. This repo
is the Python flagship of line 2, the reference for every other language.
Completeness: Python → Rust → C++ → Go. One impl, one place; discovery repos link
OUT, never duplicate. Full spec: ~/work/hanzo/SDK-ARCHITECTURE.md.
pip install hanzoai==3.2.13 # the current client
pip install hanzo # agents + MCP + orchestration helpers
uv sync --all-packages # dev: whole workspace
uv run pytest tests/ -v # testsPyPI serves this tree again. hanzoai had sat at 3.2.1 while v3.2.3 …
v3.2.12 were tagged with nothing published, and the gap was not cosmetic: 3.2.1
predates the default version leaving the operation ids, so it carries
get_v1_keys/get_v1_tools (182 api modules, 2172 models) plus the retired flat
hanzoai/api tree. 3.2.13 carries get_keys/get_tools and is what the
README's quickstart runs on. The same tag published 13 sibling packages that had
also drifted behind — hanzo-mcp 0.15.14, hanzo-tools 0.3.5, hanzo-kms
1.1.1, hanzo-network 0.1.4, seven hanzo-tools-*, and first releases of
hanzo-flags and hanzo-research.
Two faults stopped them. Six of the eight tags never started the lane at all; the two that did, failed.
hanzo.yml declares client.version:, so the release is cut by the pipeline —
regenerate, bump, tag, then push HEAD:main and refs/tags/v<next> in one push.
actions/checkout leaves an http.<host>.extraheader behind, that config is
multi-valued, and the server honours the first Authorization it reads, so the
push travelled as the forge's own Actions user (uid -2) rather than as
FORGE_TOKEN. The forge starts no run for a ref that user pushed — loop
prevention, working as designed. So the tag was on the remote, publish-pypi.yml
was in the tree at that commit, its push: tags: matched it, and there was no
event to match: v3.2.3, v3.2.4, v3.2.6, v3.2.7, v3.2.8 and v3.2.10 have zero runs
between them. js-sdk v2.2.6 carries the same signature, while the tags on either
side of it have two runs each. hanzoai/ci now clears every
http.*.extraheader before setting its own, so one credential goes on the wire;
this repo pins build.yml@v1.0.54, which carries that.
A tag pushed by automation is not the same event as a tag pushed by a person.
A green pipeline that ends "cut v" says nothing about whether the publish
ran. Read trigger_user_id on the run, or act_user_id in the repo's activity
feed — uid -2 means the push started nothing — and push a hand-cut tag with a
real account.
The two that did start, v3.2.5 and v3.2.9, then failed on a route, which reads
like a missing secret and is not one. The job asked KMS for
/v1/kms/orgs/hanzo/secrets/<path>/<key> and parsed .secret.value. KMS serves
GET /v1/kms/secrets/<path>/<key>?env=<env> and answers {"env","name","value"},
taking the org from the caller's own token claim. A wrong route 404s exactly like
an unseeded path, so the log said "KMS holds no PyPI token" about a token that was
sitting at hanzo/prod/python-sdk-publish/PYPI_TOKEN the whole time. The
route the kms-operator uses is the one that answers; check a read against a secret
known to exist before believing a 404.
The hanzo command is the Rust CLI (curl -fsSL https://hanzo.sh | sh). No
package in this workspace may declare a hanzo console script.
Both hanzo and hanzo-cli used to, and hanzo depends on hanzo-cli, so
pip install hanzo installed two distributions fighting over one name — whichever
landed last won. Measured on a clean venv at 0.4.3: hanzo --help printed
hanzo-cli's program (bot/deploy/iam/k8s/kms/login/logout/paas/s3/whoami), not
the one pkg/hanzo/README.md documented. And if the native CLI was already on
PATH, hanzo login meant one of three different things depending on install
order — the real CLI reads a bare hanzo login as an AI task, since the verb
there is hanzo auth login.
Now: hanzo ships hanzo-py, hanzo-cli ships hanzo-cli. Script named after
its distribution, one canonical hanzo.
hanzo-node on PyPI is also not the hanzo-node command. That command is a
symlink to the Hanzo CLI, installed by hanzo.sh. The PyPI package fetches a
different Rust binary from hanzoai/node — a private repo, so its release assets
404 for anyone outside the org. Both READMEs say so rather than implying one
product.
- Never "LLM gateway"; never position against LiteLLM. Hanzo is a full AI SDK / AI cloud, not a proxy.
- Zen models are our own family — never name upstream models.
- Paths are
/v1/…, never/api/…. Base host:https://api.hanzo.ai. - Voice: "Hanzo — the Open AI Cloud." Crisp, developer-first, no emoji-spam.
hanzoai/cloud emits its own router spec -> cloud/openapi.yaml [the ONE SDK input]
hanzoai/openapi generate.py + sdks.yaml -> the invocation, as data
this repo owns its test + bump + release, and pins what it projected
The client is a projection of cloud's document directly, and .spec-lock
names the commit and sha256 it was cut from. generate.py passes
--skip-validate-spec, so the 1012 missing-responses errors that once made
cloud's emission write zero files no longer stop it; hanzo.yaml is out of this
SDK's path (it still feeds the doc site and the skills plane). Regenerate with
the document by value:
cd ~/work/hanzo/openapi && uv run --with pyyaml python3 generate.py python \
--repo ~/work/hanzo/python-sdk --spec ~/work/hanzo/cloud/openapi.yamlCurrent pkg/hanzoai/cloud/ is 1814 paths / 2479 operations → 192 api
modules + 2460 model modules, 2659 importable modules in total. The document
carries 191 tags; the 192nd module is default_api, which holds the 50
operations that carry no tag (/, /.well-known/agent-skills/*, …).
834 of the 2479 operations model no response body — 716 declare no
responses at all and 118 declare responses with no content — so those methods
are typed -> None and the payload is reachable only through the generated
*_without_preload_content variant. examples/money is the worked example of
reading one honestly, including the part that is easy to miss: the raw variant
does not raise on a 4xx, because raising is part of the typed deserialization
those operations do not have.
Two renamings arrived with the lineage, and neither is a defect to undo.
IAM's types are namespace-qualified — iam.Role, iam.Application, 95 of them
— because a bare Role had been two unrelated shapes under one name (IAM's
14-property role, and a 2-property {role, user} row from another service).
Both exist now and each says which it is. And the <svc>_ operationId prefix is
gone, so every method lost it: cloud_get_v1_tools → get_v1_tools → get_tools (the default version
left the id at 3.2.10; the wire never carried it),
AIApi/APIKeysApi/MCPApi → AiApi/KeysApi/McpApi,
AdminApi.plugin_admin_plugins → admin_plugins.
pkg/hanzoai/cloud/ is generated — never hand-edit it. generate.py does
rmtree(dst) + copytree(src), so anything written there dies on the next run. Regenerate
only from hanzoai/openapi (python3 generate.py python) — never from here. The old
scripts/generate.sh was a second, destructive driver (rm -rf pkg/hanzoai, which would
have eaten the hand-written config/mcp/protocols/session/zap modules); it is deleted.
Consumed at 3.1.3: cloud 8143fc0e, openapi 2861089. Regenerate whenever either moves —
openapi 3300cda dropped {org} from the KMS secrets routes (/v1/kms/orgs/{org}/secrets
-> /v1/kms/secrets; the org is read from the token), which silently stranded 3.1.2 on a
path the server no longer serves.
The case-variant tag defect is CLOSED. hanzo.yaml used to carry 23 tag groups
differing only by case (AI/ai, Users/users, …); openapi-generator mapped both
spellings onto one module and 127 of the 411 operations in those groups never reached the
client. Fixed upstream in the per-service specs, as that note predicted. Verified on the
document this tree is pinned to: 191 tags → 191 api modules, 1:1, plus default_api
for the untagged 50, so nothing collapses, and generate.py python --check reports
[python] clean with no local strip of any kind.
Configuration(access_token=…) sends the credential. cloud's document declares
components.securitySchemes.bearer (type: http, scheme: bearer) and applies
it document-wide with security: [{bearer: []}], so openapi-generator wrote a
populated Configuration.auth_settings() —
auth['bearer'] = {'type': 'bearer', 'in': 'header',
'key': 'Authorization', 'value': 'Bearer ' + self.access_token}
— and _auth_settings: List[str] = ['bearer'] into 2498 call sites.
ApiClient._apply_auth_params reads that and sets the header. Four call sites
carry an empty list instead, and they are exactly the operations the document
marks security: []: get_models, get_models_providers, get_commands,
get_openapi_json.
Before this, the document declared no scheme at all: auth_settings() returned
{}, update_params_for_auth returned on its first line, and a Configuration
built with access_token="sk-test" produced a request with no Authorization
header. examples/client.py compensated with ApiClient's
header_name/header_value pair. That compensation is gone — the flows pass
access_token and nothing else, which is the shape a reader of any other
openapi-generator client already expects.
Proven on the wire, not by reading: python -m examples.hello against
api.hanzo.ai returns the caller's keys with a real sk-, and the same command
with a bogus one returns HTTP 403 {"code":"forbidden","error":"sign in to manage API keys"}. Two different answers to the same code means the credential
is reaching the server.
cloud.APIKeyPrefixes is {"pk-", "sk-"}, and it is tempting to read that pair
as a permission split — publishable for reads, secret for writes. It is not one.
middleware_identity.go returns nil for any pk- before it ever consults the
key store: "a key meant for a browser bundle must not read … resolvable, not
authenticating". A pk- resolves to an org so an analytics beacon can be
attributed to a tenant, and that is the whole of it.
So every route these examples use refuses a valid pk- exactly as it refuses no
key at all — /v1/tools says why in as many words, "a validated principal is required" — and the 403 that comes back reads like a revoked key rather than the
wrong shape of key. examples/client.py rejects a pk- up front for that reason:
an unauthenticating credential produces the same misleading refusal as a revoked
one, so it is caught before the request goes out.
Two spec defects were found and fixed upstream while regenerating at 3.1.5. Neither was
patched here; both are in hanzoai/openapi main:
fc0c17a— 35/v1/platformoperations carried noresponses. OAS 3.x requires it and openapi-generator aborts the entire document, sohanzo.yamlwas producing no client in any language, not just Python.07783f5—ChatCompletionResponse.choiceswasitems: {type: object}, sochoices[0].message.contentwasList[object]and unusable without a cast. Now anai_ChatChoiceschema.
The rule holds in both directions: a generated tree is never hand-repaired, and a defect found by generating is fixed in the spec, where every other language gets the fix too.
examples/{models,hello,money,store,agent,tools}, one directory each, plus
examples/client.py as the single place a base URL or an env var is resolved. Run one with
python -m examples.hello from the repo root.
models is the one that needs no credential — GET /v1/models is one of the four
operations the document marks security: [] — so it is the install check a reader can run
before they have a key, and the flow that proves the package reaches api.hanzo.ai at all.
client.py exposes it as public() beside the credentialled client().
chat is absent by measurement, not by choice: POST /v1/chat/completions is declared with
no requestBody and no responses, so the generated method takes no arguments and returns
None — the one call the flow exists to make cannot be expressed. It returns the day the
document describes the body; hanzo.yml carries the one-line test for that.
Five loose scripts used to sit beside the flows (using_grok.py, unified_ai_example.py,
self_learning_agent.py, parallel_ai_doc_editing.py, worktree_orchestration.py) and all
five were dead: they imported hanzoai.Hanzo, hanzoai.cluster, hanzoai.agents,
hanzoai.completion — none of which exist — or were dict-literal sketches captioned "in
practice this would be called through the MCP interface". compileall passed them all,
because syntax is not a claim. They are deleted. examples/ is the flows.
Each flow's call sits behind if __name__ == "__main__": on purpose. That is what lets CI
import all six to prove every from hanzoai.cloud import X still resolves, without an API
key and without opening a socket — so a spec change that renames or drops an operation goes
red in the gate instead of in a user's app.
They are a gate, not decoration. The TypeScript twin of the chat flow is what surfaced the
choices defect above: the generated tree imported and built perfectly, because building
generated code only proves it is internally consistent. Only calling it proves the surface
is usable.
Fleet convention: root hanzo.yml (the test: gate and pypi:) plus
.github/workflows/cicd.yml, which calls hanzoai/ci/.github/workflows/build.yml@v2 and runs
on GitHub. The gate is four blocks — import every generated module (for generated
code that IS the build step; there is no compiler to catch a bad $ref), report the imports
no package declares (report only), read the syntax tree for duplicate fields the import
cannot see, then resolve and import the six flows. Each provisions an interpreter with uv
when the runner lacks one.
Scope is deliberate: the cloud client and its flows, not all 65 packages. A red gate should mean "the client the spec just produced is broken", not "something, somewhere".
Publishing is hanzoai/ci's Publish to PyPI step, on a tag only. v* publishes every
pypi: [., pkg/*] project whose version PyPI lacks (twine --skip-existing);
<name>-v<version> publishes the one whose pyproject name matches. Each wheel is installed
alone in a clean venv and imported before upload, with the tokens KMS holds at
python-sdk-publish (PYPI_TOKEN, then HANZO_AI_PYPI_TOKEN). The publish job runs the
client check first: it regenerates pkg/hanzoai/cloud from https://api.hanzo.ai/v1/openapi.json
and fails on any drift, so once production's document moves past .spec-lock no package here
publishes until the projection is moved (workflow_dispatch with a spec-ref); a tag on a
drifted tree publishes nothing.
The examples step used to import the flows and stop there, and the comment beside it said
so honestly — a method name is looked up at call time, so a renamed operation passed the
import and failed in a user's app. It now resolves them: the syntax tree gives every
attribute access on a *Api-bound name, and the class is asked whether it has it. Ten names
resolve today, and a stale get_v1_tools fails the step in the same second the import
passes.
Three docs under docs/ were fabrication, not drift: FEATURES.md
(from hanzoai import cluster/agents/mcp — none exist), QUICKSTART.md and
GPT5_ORCHESTRATION.md (invented console output for CLI flags and models that were never
ours). None were in the mkdocs nav, so nothing rendered them and nothing checked them.
Deleted. pkg/hanzo-agent told the reader to pip install hanzoai and
from hanzoai import Agent, Runner — the cloud client has no Agent — and its own full
extra resolved to hanzoai[web3,tee,marketplace,cli], extras the cloud client does not
declare, so it installed the client and none of the extensions. Both corrected to
hanzo-agent / from agents import.
pyproject.toml said BSD-3-Clause while LICENSE is the Apache 2.0 text, so the wheel's
metadata contradicted the file inside it. Metadata now matches the file: Apache-2.0.
tests/test_smoke.py imported hanzoai.cloud.api.tracker_api; no /v1/tracker path is
emitted any more, so the suite had a failing test that named a module the client does not
have. It reads analytics_api now, off the client.
hanzo-tools-api's hanzo_tool.py is the one unified tool: one MCP tool over
every service cloud serves, its service/action surface derived from
/v1/openapi.json at runtime with a disk cache, so a newly mounted app is
callable the moment cloud serves it.
The contract is not the agent surface, and that gap was live. cloud keeps an
operation off the agent surface when its name discloses a bearer secret at any
verb, or when a mutating verb acts on identity or authority. /v1/openapi.json
carries them anyway, because it describes the API rather than what a model is
handed — measured: post_iam_users is in the contract (2,265 operations) and is
refused at /v1/mcp. So this tool offered an identity mutation the fleet declines.
spec.py now filters by catalog.json, generated out of cloud's own typed
operations by plugin/gen-mcp-catalog, which asks fleet.Withheld — the same
predicate the endpoint asks. Two facts, one source each: the document supplies
each operation's METHOD and PATH, which a caller needs to make the request, and
the catalog supplies which operations are OFFERED. The rule itself is never
restated here. An unreadable catalog offers NOTHING rather than everything, since
failing open would widen the surface silently.
It is the same file @hanzo/mcp and the Rust hanzo-mcp crate embed. Refresh
every runtime's copy at once with pnpm sync:catalog in hanzoai/mcp.
Two aliases pointed at names the fleet had left behind — platform -> paas
and identity -> iam — so they mapped a caller off the live surface. A synonym
may only point AT a name the fleet serves; knowledge/rag -> kb stay.
A test fixture that names no operations is not exercising the offer rule, and
says so: test_spec_catalog.py and test_api_tools.py pass an explicit
everything-allow for their synthetic specs, and the rule gets its own test
(test_the_offer_rule_filters) rather than the default being weakened to keep
them green.
A model was handed secrets, and the fleet had already said no. Nine per-service
packages registered a hanzo.tools entry point AND sat in hanzo-mcp's default
dependencies, so pip install hanzo-mcp put them in a model's tool list — beside
the unified tool, and without its filter. What that offered:
| package | actions reaching a model | what the fleet offers an agent |
|---|---|---|
hanzo-tools-kms |
list get set delete inject |
get_kms_config, get_kms_health — and nothing else |
hanzo-tools-iam |
create_user delete_user update_user tokens sessions roles |
the reads; every one of those is withheld |
hanzo-tools-team |
create_workspace delete_workspace invite |
the reads |
inject is the sharp one: it lists a path and reads every secret at it, in one
call. cloud's rule exists to prevent exactly this — "a tool is not projected when
its name discloses a bearer secret at any verb, or when a mutating verb acts on an
identity or authority object" — and these packages were a second, unfiltered way
to the same API, so the rule held on one path and not the other.
The auto-registration is withdrawn, not the packages. iam, kms, team,
billing, commerce, ingress, paas and s3 no longer declare
[project.entry-points."hanzo.tools"] and no longer ship in hanzo-mcp. They
stay importable for a human at a CLI, which is where reading a secret is a
legitimate act. An agent reaches all eight through the unified hanzo tool, whose
surface is filtered — verified against the live document: iam 41 operations, kms
2, team 7, billing 35, commerce 5, ingress 18, platform 34, s3 6.
Two stay registered, for reasons worth stating. hanzo-tools-mpc has NO
equivalent in the fleet catalog, so unregistering it would remove capability with
nothing to replace it. hanzo-tools-auth is a login and session tool — it reads
the CALLER's own claims and verifies tokens against the IdP's signing keys, which
is not another identity's secret and which no catalog replaces.
paas is the name the fleet left behind. It is platform there, which is why
the retired alias mattered: a caller typing the old name was mapped off the live
surface rather than onto it.
pkg/hanzo-tools-devserver registers devserver (index, call, errors, help).
hanzo_tools.devserver.discover() is the seam: plain DevServer records (port, url,
pid, framework, version, root, command, mcp, tools), one per listening port — the
shape a ZAP node of kind devserver takes.
- Identification: argv basename (Next renames its server
next-server (vX)), the nearest package.json naming a framework (most specific first,vitelast), and psutil's listening ports for the process. - MCP: Next 16 serves streamable HTTP at
/_next/mcp; the Vite family serves SSE at/__mcp/sseonly withvite-plugin-mcp/nuxt-mcp-dev. A probe tries http, then https, and caches the scheme that answered per port. - One client:
mcp_proxy.MCPServerConfig(url=…)givesMCPServerConnectionan HTTP/SSE transport through the SDK (http_session); a loopback URL skips TLS verification. - Next's
get_errorsanswers for connected browser sessions only (measured on 16.3.7). Atloadthe session is connected but has not reported the build error yet; atnetworkidleit has. Soerrorsopens the app through thebrowsertool withstate=networkidlebefore asking. - Vite writes a transform error to its overlay, not the console.
errorsreads thevite-error-overlayshadow root. A plain.jssyntax error is no transform error in Vite 8; it reaches the browser and surfaces as a page error. - The browser keeps console messages and page errors across page loads, so
errorscounts them before navigating and returns only the new ones. - Tests run MCP servers in a subprocess: the SDK's streamable HTTP server leaves memory streams unclosed, and in-process the warnings-as-errors config blames the client.
pkg/hanzo-kai (import hanzo_kai) is the Python client for Kai: POST /v1/decisions
(Kai.decide, AsyncKai.decide → Decision) and GET /v1/models narrowed to the models whose
outputs include decision. It depends on httpx and pydantic ≥ 2.10 (the first to read its
PEP 695 aliases) and nothing else; Python ≥ 3.12.
Its surface is one surface with the TypeScript @hanzo/kai: typesafe-sdk 0.7.2's call shapes
under Kai names (Kai/AsyncKai, decide, Decision, Choice/Noul/Score, the APIError
family, RetryPolicy, HANZO_API_KEY, HANZO_BASE_URL, KAI_MODEL, KAI_LOG_LEVEL).
tests/test_surface.py pins the names and signatures, so a rename fails here before it splits
the two. The client checks only what the server cannot see (at least one question, a score's
criteria a list, a choice's a map or list); every other rule is the server's 422, and its
sentence becomes error.message. hanzo/kai bodies arrive with sorted keys, so answers are
read by name, and score maps are keyed and ordered by int level.
hanzo_kai.jev is the Jev-compatibility layer: Client.system_one on POST /v1/systemone, Jev's
body as Response, FastAPI errors as the same classes, and models.list() presenting the decision
models of data in Jev's shape, because api.hanzo.ai keeps the models key empty. from hanzo_kai.jev import Choice, Noul, Score, Client as TypeSafeClient ports a TypeSafe program. A
refusal over reach is 422 with error.code a name on both paths (state_too_long,
question_too_long, option_too_long, request_too_long), as hanzoai/decision's
decision/src/error.rs writes it.
Tests: cd pkg/hanzo-kai && uv run pytest, over httpx.MockTransport with no network, each
client test on both flavours; they are outside hanzo.yml's gate, whose scope is the cloud
client. tests/conformance/*.json states one contract rule per file for both paths: the suite
runs them against conformance/fake.py, and uv run python tests/live_conformance.py runs them
against api.hanzo.ai and prints pass or fail per rule. Release: tag hanzo-kai-v<version>, and
https://pypi.org/pypi/hanzo-kai/json is the proof, not a green run.
read_usage(headers) → Usage(usage, usage_class, paid_by, fallback, served, reason) from
the X-Hanzo-* headers, case-insensitive; an absent header is None. UsageLimitError
(a Fault) with one subclass per AI-router refusal code — PlanAllowanceUsedError,
PaidPlanRequiredError, FreePlanCapError, ModelCapError, UsageCapExceededError,
InsufficientBalanceError, the JS and Go names, plus window (the spent session or day). refusal(reply) reads only the router's
nested {"error": {code, ...}} body (or a controller's {status: "error", code, msg}); the money gate's flat body stays Denied.
Client.send and Client.response_deserialize raise it, so every generated operation run
through hanzoai.Client does; a bare generated ApiClient still raises ApiException.
The rest is generated, typed, and needs nothing hand-written: AiApi.ai_limits /
ai_set_limits, SyncApi.get_sync / get_sync_by_id / post_sync /
post_sync_by_id_run, AiApi.post_decisions, AiApi.get_models (ModelInfo.var_class
is the wire's class; pricing.variable). /v1/models ignores ?class=, so filter
client-side. Headers: the *_with_http_info variant's .headers into read_usage.
ai.DecisionsChoice.criteria is an object in cloud's document, so the [label, ...] form
the server also takes cannot be sent through the generated client.
Hand-written root modules ship with the next cloud fanout. The root version is
cloud's; the fanout's v8.5.N tag publishes whatever pkg/hanzoai holds at that commit.
Never cut a root version by hand.
Commit with LEFTHOOK=0. The global hook falls through to uv run lefthook -h, which
re-locks uv.lock with the local uv and syncs a .venv on every checkout and commit.
pkg/hanzoai/— the client (ApiClient,Configuration,*Api) undercloud/, plus seven hand-written modules beside it (config,mcp,protocols,session,zap, …).pkg/hanzoai/{api,models}is GONE from git; if a checkout still showsresources/ortypes/on disk they are untracked leftovers of that surface, and the wheel excludes them — the published 3.2.13 wheel is 2667 files ofhanzoai/cloud/and those seven modules, nothing else.pkg/hanzo/src/hanzo/cli.py— thehanzoCLI command tree.pkg/hanzo-mcp/— MCP server; tools via[project.entry-points."hanzo.tools"].pkg/hanzo-tools-*/— one concern each; 30 of the 39 register aTOOLSlist under thehanzo.toolsentry point (hanzo-tools-coreis the shared base, and the eight service packages withdrawn above register none).pkg/hanzo-{agents,agent,network,memory}/— agent/compute/memory libraries.pkg/hanzo-kms/— KMS client. The server is luxfi/kms (kms.hanzo.ai,kms.lux.cloud) and its whole surface is/v1/kms/auth/loginplus/v1/kms/orgs/{org}/secrets[/{path}/{name}]./api/*is Infisical's and was never served — it looked like a decode error rather than a 404 only because old builds answered every unmatched path with the console SPA (200 text/html). A secret is (org, path, name, env), one value each — no versions. The server splits the trailing URL at its LAST slash into (path, name), so escape each segment individually.pkg/hanzo-kms/tests/pins all of it.
Rules for agents: update THIS file with significant discoveries; never write random summary files; keep the README cross-link block intact.
