It records the asked-for one. CacheMW sits outside the transport in the
onion, so at lookup time the nearest-mapping has not happened yet and the
applied tier does not exist. Telemetry's success rows do record the mapped
tier, which is where the confusion came from — the warning conflated the
two and would have sent anyone debugging a cache miss the wrong way.
Also repairs the design doc: the 2026-09-05 rollback note had been spliced
into the equivalence table, orphaning its last row, and §3.1 still said
seven tiers after `auto` made it eight.
CHANGELOG gets all five breaking changes, not the one the draft had:
ThinkingCapability's constructor, two ports that grew a parameter with
no default, resolve_thinking's new return type, and ProviderProfile's
single wire field. Behaviour changes get their own section, including
the one that is easy to miss — the openai fallback segment no longer
refuses an unknown shape, so a downstream that parks a foreign model
there and asks for thinking used to fail at assembly and now sends
nothing at all. minimax is called out as the exception it is: the gateway
proved M3 does not think without a parameter, so that segment keeps its
medium and its downstreams see no change this release.
The capability table is reported as it stands — 17 of 24 rows measured,
7 still on documentation, with the reason each one went unmeasured, so
nobody reads "measured" into a row that is a guess. The auto limitation
and its deliberate MiniMax-M3 inconsistency are written down rather than
left for someone to trip over; issue #21 holds the real fix.
ARCHITECTURE had five claims that measurement showed had gone false:
the cache key formula, the field count, the reconcile predicate and its
throttle key, and two field lists. README's FIELD set was missing the
two new keys it calls exhaustive.
docs-convention still opened by announcing a 17-page site that has not
existed since August. It now says what is actually there — one placeholder
page pointing at .env.example, CHANGELOG and the source docstrings — and
says which four files carry the sync gate while the site is down.
The minimax wire lost its tier value on the assumption that these models
reason by default, so injecting nothing still reads as "on". T10 measured
the real gateway and the assumption does not hold: MiniMax-M3 with no
reasoning parameter did not reason in 5 of 5 rounds, while all six
strength values worked. Existing downstreams on ENABLE_THINKING=true
went from reasoning to silently not reasoning, and the capability table
cannot catch it because phase 5 lets auto through unconditionally.
Restore on_base to the old {"reasoning_effort": "medium"} verbatim. This
is a stopgap - it hands the tier choice back to the library, which this
work set out to remove. The real fix is to constrain auto by the
capability table, a public behaviour change tracked as issue #21.
The assertions that said "minimax injects no tier on the on-tier" go
back with it; each carries a note on why it moved twice.
Twenty-five columns and not one of them answered "which tier was this?",
so the question the whole issue exists to settle - does a higher tier buy
anything - had no way to group its data.
The three emit entry points deliberately disagree, the way sampling
already does. A successful attempt records what the transport actually
sent: with EFFORT_FALLBACK=nearest a request for medium goes out as low,
and recomputing here would file the row under a tier that never left the
process. A failed attempt has no response to read, so it falls back to
the requested tier - which is exactly right for the tier errors that are
rejected before any HTTP happens, because the rejected tier is the
signal. Cache hits and terminal failures have no chosen source at all,
so a source-level tier is not a thing they could report.
emit_attempt now demands to be told whether the path reasons at all.
Embedding and OCR share the emitter but never send reasoning parameters;
without the flag a source that mistakenly carries ENABLE_THINKING would
hang a tier on a call that could not possibly have run at one.
The value lands as a plain str. StrEnum is a str subclass and asyncpg
promises nothing about encoding subclasses, and a telemetry write that
fails is only a warning - Postgres would just quietly lose the column.
NULL means nobody declared a tier, which is not the same statement as
'none', and the two must never be folded together.
A provider that registered a disable form but no enable form was told
its shape was unknown and pointed at register_provider -- work it had
already done -- for a request that only ever needed the disable form.
The old bool code took the slot by direction; the tiered rewrite lost
that. Take the relevant field again, and keep "shape unknown" for the
case where both halves are missing, so the "cannot disable" wording
still owns the half-missing case.
Codex found the per-call tier never reaches the transport: the protocol
takes five unpacked arguments, not the request, so a field on ChatRequest
goes nowhere. That is now its own step, fakes included.
It also found the mapped tier would be lost — resolve_thinking returned
only the payload, so telemetry would file a mapped call under a tier it
never ran at, which is exactly the grouping task 10 depends on.
The entity pages carry the rejected alternatives and why, so the next
reader does not have to reconstruct the argument: minimal patch cannot
fill a tier that does not exist, cherry's wire DSL buys four endpoint
protocols we do not have, and default_effort lost its only consumer the
moment enable_thinking=True became Effort.AUTO.
Ordered so the two type changes land first and everything else consumes
them: capability and wire in parallel, then the five gates, then the two
entry points, then cache key and telemetry, then the transport.
Task 10 exists because the human settled that the capability table is
measured through new-api, not read off a vendor page. Task 1 lands the
documented guess; task 10 replaces it with what the gateway does.
Codex argued `effort_fallback` had no verifiable consumer and could wait.
The human overruled that: swapping models is routine, and between "it
stops booting" and "it silently costs more" the caller deserves a middle
option it selects on purpose. So the mapping ships with this round.
issue #20 asks for one zhipu profile. Adding it does not fix what the
issue describes: GLM-5.3 mandates thinking (three sources agree, the
vendor included), so `none` is an undefined value we were sending, and
`medium` — the tier our minimax profile hardcodes — does not exist on
GLM, kimi or deepseek at all.
So the gap is the type, not the table. Capability becomes a tier list
where `none`'s presence answers "can it be turned off", and refusal
carries the cheapest tier that model does support — a refusal with no
way forward is what sent the caller to extra_body in the first place.
Reviewed by Codex, which caught two claims that were wrong: source-level
extra_body and enable_thinking already reach the cache key through the
model fingerprint, and the three reference projects are not in the
workspace, so "no callers" was a grep against absent directories.
Both reviews landed on the same line independently. _as_role swaps the
credentials in the DSN with a regex, and when the pattern does not match
it returned the string unchanged. Two shapes miss it: no inline
credentials, and a unix socket URL. Either one is a legal DSN.
What that costs is not a broken test. The sandbox builds, every
assertion still passes, and bare_dsn is now the admin connection, so the
worst-case case runs the real script with --apply as a superuser against
the shared table. The verifier ran that command as a dry run to see what
it would have done: target public.llm_calls, 11 rows to delete. The case
would still have gone red on the exit code, after the rows were gone.
It raises now. There is also a second check that connects and compares
current_user, because a successful string substitution is not the same
as connecting as that role -- PGUSER and friends still override. The
whole design rests on that connection having no grant on the shared
table; a string comparison is too thin a thing to rest it on.
That check has to stay inside the try. Past it the cleanup statements
have already been merged into the fixture-level stack, and unwinding
again runs DROP OWNED BY twice, which has no IF EXISTS.
The catalog probe took any SQL and ran it on the admin connection. The
design claims withholding the DSN makes the boundary structural; that
was only true of the connection string, not of the capability. It takes
SELECT now.
--table's schema half is restricted to plain identifiers. Not a
security fix, since the name goes through a parameter and _quote: the
help text says complex identifiers are unsupported and the code was
accepting them anyway.
Until now the target came from whatever search_path resolved to. The
script printed what it found, but that print and the DELETE happen in
the same run with nobody in between, so it only ever helped the person
who ran a dry-run first. Swap the role that runs it and "$user" can
resolve somewhere else entirely.
--table takes the whole qualified name and resolves it directly. The
table half has to be llm_calls: a version that accepts any name turns
one typo into a general purpose row deleter, and any table with a
created_at and a tenant_id would go through the same batched DELETE
without complaint.
The tests that run it now run as a role that owns its own scratch table
and holds nothing on the shared one, so the row-count snapshot could
go. What replaced it is a case that lets the script fall through to the
shared table on purpose and asserts it exits 2 having deleted nothing.
That one has no red-first path, since making it red means running it as
the superuser, which is the thing being prevented; the finding's probe
covers it instead.
Five of the new usage tests passed before the flag existed, because
argparse rejects an unknown --table with exit 1 and the word --table in
stderr, which is exactly what they asserted. They now also assert the
error is not "unrecognized", which is the difference between testing
the validation and testing argparse.
The plan's one irreversible risk is the worst-case test itself. It
deliberately lets the script fall through to the shared table, and the
account in .env is a superuser, so running it before the sandbox role
exists would delete every expired row in there. All eleven rows on that
table predate any cutoff the tests use.
That forces the order: factory, then the retention tests move onto an
owner role, and only then does the case get written. Review caught that
the original order also made the --table integration cases impossible
to fail first, since the tool would already be implemented by the time
they were written. Same fix resolves both.
The worst-case case has no red-first path at all. Turning it red means
running it as the superuser, which is the thing being prevented, so its
evidence is the probe in the finding instead, and the plan says so
rather than calling it verified.
One acceptance criterion in the design turned out to be unrunnable: the
hint line only prints on the Postgres branch, so no unit test that
never connects can assert it. Corrected in place.
The failing assertion was never testing the script. It compared the row
count of a table three other projects also write to, before and after
the run, and the failure it reported (61 rows became 12) landed while
the script under test was demonstrably confined to its own schema.
A row count cannot carry the property that assertion stood in for. It
goes red when anyone else writes, and green when an outside insert
happens to cancel out a wrong delete. The second half is the one that
was guarding against a dropped audit table.
So the property moves to where the database enforces it: the script
runs as a role that owns its scratch table and holds no grant at all on
the shared one. Falling back to public stops being something a later
assertion might notice and becomes permission denied. Measured, along
with the rest of the Postgres semantics this rests on.
The tool grows --table so the target stops being whatever search_path
resolves to. The table half is pinned to llm_calls: without that, one
typo turns a telemetry cleaner into a general purpose row deleter.
Codex raised six problems and all are folded in. The one place this
still disagrees with it is recorded with the reason.
The reasoning_tokens docstring was still teaching downstream to treat
None or 0 as no reasoning. The changelog and the schema page had both
been corrected; the docstring had not, and it is the copy that ships in
the wheel and shows up on hover. Someone writing a report from it would
have counted every real MiniMax reasoning call as not reasoning, which
is issue #16 all over again with the tests green.
The original wording stays, since reading pre-1.3.1 rows still needs
it. What follows it now says when it expired and what to read instead.
Two more places had drifted the same way: the changelog and the
architecture doc described the throttle and the cache fallback as they
were before this review, which is to say as the opposite of what the
code now does.
The claim that the two throttle sets would suppress each other does not
survive checking, as the mutation testing showed: their key spaces do
not overlap. Keeping them apart is still right, but for the honest
reason, which is that the two warnings have unrelated lifetimes.
The telemetry field count is taken from inspect.signature, not from
memory, because that is the one the release checklist keeps catching.
llm-calls.md said 22 and was two rounds stale; fixing the title alone
would have left the table contradicting it, so tenant_id and meta are
documented too.
The production template needed no new column — it derives them with
LIKE. What it gained is an assertion that it must keep deriving them
and must not inline a column name, which is the drift that could
actually happen.
The changelog leads with the three breaking items. A patch number
carries no warning by design, so the entry has to.
The README's production template does not hand-write its columns; it
derives them with LIKE from the seed table, and the prose right above it
says so. Telling an executor to add a column there would have made
Postgres reject a duplicate, turned TestProductionTemplate red, and
broken deployment for anyone following it.
The claim came from another task's report and went into the plan without
opening the README. A finding relayed across tasks is a lead to verify,
not a fact. What replaces it is a shape assertion — the template must
derive via LIKE and must not inline any column name — which pins the
real risk of someone copying columns in later.
Also adds the Gitea wiki sync the plan had missed: docs-convention makes
a version bump commit illegal on its own.
The README carries a hand-written production DDL template that no test
ever compares against COLUMNS, so it can fall a column behind and stay
green. Downstream deploying from it would get a table without the new
column and the library would silently trim it — the same silence this
issue exists to remove. Task 9 now fixes the template and adds the
same-source assertion.
Also records two things the implementation disproved: caplog cannot see
loguru output, and reconcile_thinking has to be defined after the
dataclass it annotates, since this module evaluates annotations eagerly.
And the column-count table was incomplete — six more spots go red.
Both recorders are (self, **fields), not explicit parameter lists, so a
new column needs no signature change on them — COLUMNS plus an emitter
that passes it is enough. The port Protocol stays explicit because that
is where the emitter's contract and the freeze test anchor.
Everything up to and including the full slow suite runs on the branch
without asking. Merging to main, pushing a tag, and uploading to the
registry cannot be taken back, and a registry version number cannot be
reused, so those wait for an explicit yes.
Also settles three things an executor would have tripped on: the
_AttemptUsage field is typed as the enum with .value applied only at
the recorder boundary, __all__ is not in strict alphabetical order, and
the port signature test freezes two params rather than the full list.
Each task carries its own failing-then-passing evidence and a command
whose output decides whether it is done. Two traps are called out where
an executor would otherwise walk into them: the enum has to live in
types.py or import-linter rejects the layering, and the 24 in
test_telemetry.py line 1787 counts OCR placeholder characters, not
telemetry columns.
The enum belonged in types.py all along: making LLMResponse field-typed
on a symbol defined in thinking.py would have had the innermost layer
import a decision module, and import-linter would have caught it only
after the code was written.
The 4.1 table claimed reconciliation could still catch a failed disable
while section 5 said UNKNOWN never speaks. UNKNOWN has no falsifying
power; the guarantee only covers observable paths, and the doc now says
so instead of pretending otherwise.
Section 12 was written against a misreading: _record already is the
single helper the ironclad rule asks for, so there was no debt to
decline. Landing sites had missed ports.py, whose record_llm_call
freezes 24 explicit params with no defaults, and cache.py, where
_rehydrate revives the enum as a bare string.
The design argued for 1.4.0 because a broken deep-path import hidden
behind a patch bump is a debt handed to downstream. The call is 1.3.1.
Since the version number no longer carries the warning, the CHANGELOG
has to: breaking items and their fixes go first in the entry, following
the 1.3.0 read-this-first form.
The four red e2e cases were blamed on MiniMax-M3 no longer reasoning.
Raw gateway probes show the opposite: M3 reasons fine (124 chars of
reasoning_content, prompt 194 to 216, completion 3 to 60). What changed
is that the MiniMax route stopped returning completion_tokens_details,
while qwen and deepseek still do on the same gateway and key. The
library already holds 185 chars of proof in LLMResponse.thinking and
never feeds it into any verdict.
The design turns that verdict into a first-class return value judged
from multiple signals, says UNKNOWN when a single response cannot tell,
and reconciles it against the capability table so a stale declaration
becomes a warning instead of a silent illusion.
ARCHITECTURE 7.8 gains the pool resource semantics, the two-sentence
failure verdict and the two config keys; the ownership rule lands in a
new 4.5 because it is a cross-subsystem discipline, not a telemetry
convention. CHANGELOG leads with the three items downstream must read
first: the 3.12 floor, the connection count going from 10 per client to
on demand, and aclose no longer closing injected components.
The design traces the incident to four stacked defects rather than one bad
default: the pool is the only resource in the library that pre-allocates,
the kill switch keys off which step failed instead of what failed, the
degraded state can neither recover nor be observed, and the ownership rules
make the sanctioned sharing path unusable.
The plan sequences the tracker ahead of the pool and failure work so every
commit stays green, and records two facts the implementer needs up front:
the pool-construction path has zero test coverage today, and the commit
gate runs the full suite plus a complexity ceiling.
Records what the two Codex review rounds found, which findings held up
under verification, and how each was resolved -- including the one that
changed docs rather than code. Also lists the evidence behind the
completion claim: suite counts, coverage, the 19-minute real-wait Redis
run, and the import contract.
Branch review caught the docs claiming something the code does not do.
CHANGELOG, README and the design's behaviour matrix all said a
force-opened source under circuit_open=wait waits out the full stall
window. It does not: the probe let through after each cooldown is a
real attempt, so it burns a max_attempts slot like any other, and a
401 source usually runs out of retry budget first -- reason is
retry_exhausted, not stalled. Which budget wins depends on
max_attempts against the cooldowns and the stall window.
The behaviour is right; only the prose was wrong. Charging the probe
to the retry budget is exactly the split issue #8 settled: the
question is who spends max_attempts, and a probe does send a real
request. A test now pins it so the claim cannot drift again.
Also drops the planned "woke up" log line. Each wait round already
logs on entry with its duration, and a still-blocked wake-up logs the
next round immediately, so a second line would only double the volume.
