Independent verification caught that the split shipped in the previous
commit did not actually hold on the only path production uses. The gate
wrappers re-raise GovernanceBackendError but nothing else, so
SourceNotConfiguredError fell into the following `except Exception` and
came back out as a governance_backend_down failure with retry_after_s=5.0.
A misconfigured source name would still retry forever and never surface.
The existing tests missed it because both of them call the private _cfg()
directly, one layer below the wrapper the governance loops actually go
through. The regression test goes through QuotaGate.
telemetry.py has to widen its terminal catch in the same commit: once the
wrapper stops relabeling the error, it is no longer a GovernanceBackendError,
and it is raised before any attempt exists, so the path would have recorded
no telemetry at all.
Also corrects the leak path count from three to five. QuotaGate.stats and
BreakerGate.retry_after_s are not wrapped by _record_quietly either.
Minor rather than major: adding a parent class widens what an existing
`except` catches, it does not break one. Callers already catching
GovernanceBackendError keep working untouched.
The wiki sync in the release checklist is a no-op this time. The doc site
was taken down entirely on 2026-08-02 for accuracy reasons, and its
remaining landing page points at CHANGELOG.md as the version source of
truth, which this commit updates.
The thinking matrix had been running inside make ci all along, which is
not what the design claimed. It takes seven minutes, spends 137 real
calls, and its criteria are statistical, so a network hiccup fails the
build for reasons unrelated to the change under test -- one run died on
three consecutive network errors exhausting the source.
The project already has the mechanism for this: the slow marker, which
addopts excludes by default and the config comments describe as "CI runs
it on demand". Marking the matrix slow brings make ci back down from
seven minutes to ninety seconds while the matrix stays a merge
requirement via -m slow.
The design also claimed e2e does not run in CI. It does: make test runs
pytest over tests/, e2e included, and the existing smoke tests really
call the gateway whenever .env has credentials. Only slow-marked tests
are excluded. Both documents now say so.
Version sources are pyproject and __init__; a test enforces they agree,
and it caught the second one being missed.
A sixteen-row matrix over 127 real calls: disable and enable on
MiniMax-M3 in both streaming and non-streaming mode, extra_body winning
over the profile slot, qwen and deepseek still disabling correctly, a
drift sentinel that re-derives every registered capability from live
behaviour, and the assembly guard refusing the models that cannot
comply.
Two judgement criteria had to be corrected by the data they were meant
to judge. Output length cannot separate the two regimes at all -- the
disabled runs reach 46 tokens when the model narrates its working in
the visible answer, and the enabled runs drop to 13 when medium effort
barely thinks. reasoning_tokens separates them cleanly in both
directions, which is precisely what issue #6 was collected for. A
second anchor compares prompt_tokens between the two regimes: the
vendor injects a reasoning instruction when thinking is on, so the
input side grows, and comparing the two runs relatively avoids
hardcoding any vendor number.
Provider names are mapped explicitly rather than guessed from the model
string; guessing had silently skipped the qwen row behind a "source
unavailable" reason that was not true.
Patch level: no field or env key was removed or renamed, no port
signature moved, and the API stays backward compatible -- what changed
is the telemetry data contract, which the changelog spells out for
downstream cost rollups.
Mutation testing showed the negative structured-retries and expected-dim checks
in the env parsing path could be deleted with every test still passing. Their
value is the env key name in the message, so they need tests that assert it.
Changelog now states the real scope of this release and warns that normalising
scope moves the Redis keys, the one change here that silently relocates runtime
state. Records the breaker threshold derivation as deliberately env-only so it
does not resurface as another round.
The verifier found four more env-only behaviours of the same class the branch
was already fixing. The worst is scope: it goes straight into the Redis keys
(pgw:limit:{scope}, pgw:gate:{scope}), so one process using from_env("LLM")
and another constructing scope="LLM" by hand split the rate limit and breaker
state across two namespaces, each tracking its own quota, with no error.
Blank redis_url and pricing_path now collapse to None as from_env has always
done, so they fall into the required-field checks instead of reaching the redis
client as an unparseable URL. EmbeddingSettings gains the __post_init__ it never
had, moving its batch_size and expected_dim checks off the from_env-only path.
Also adds the cache backend whitelist test that mutation testing showed missing.
Round two of the from_env-only validation problem. Fifteen checks still lived
in the env parsing functions: six enum domains, the redis_url requirement for
redis-backed limiter/breaker/cache, cache namespace and TTL, telemetry path and
DSN, non-negative structured retries and non-blank scope. from_settings and
direct construction bypassed all of them.
The five asserts in client.py that claimed config had already validated
redis_url and the telemetry targets now hold on every path, so they revert to
what CLAUDE.md permits: internal invariant declarations that also narrow the
Optional for type checkers. Their comments now name the method that guarantees
them, since the previous wording is exactly what went stale.
Postgres DSNs built by hand now get the SQLAlchemy +driver suffix stripped the
way from_env has always stripped it, with a warning so the rewrite is not
silent. The env path strips earlier, so it stays quiet.
Corrects the changelog claim that the old guard messages only named env keys:
they named fields too, it was the remediation advice that pointed at env keys.
Records the human approval of the design, the mutation-testing evidence from
the independent verifier, and the same-class gap it found: 14 checks (redis_url
presence, telemetry paths, enum validity) still live only in from_env, while
client.py asserts they were already validated. Deliberately out of scope here.
Patch release for the settings invariant fix. The changelog carries a separate
'behaviour tightening' section because a patch number gives downstreams no
warning that construction can now raise where it previously did not.
