Findings: live-API measurements across MiniMax M3/M2.7/M2.5, qwen and
deepseek, plus a survey of how nine unified gateways model per-model
parameter divergence. Key facts: reasoning_effort is MiniMax's real
switch, M2.x reasoning is mandatory and cannot be disabled, and the
relay's local token-count fallback silently drops reasoning_tokens.
Design: keep the parameter shape at provider level, push capability
down to model level, split "unknown" / "unsupported" / "no opinion"
into three distinct values, and fail at assembly time when a model
cannot honour enable_thinking=False.
The test passed overlay and sampling as separate objects while production
aliases them, so an in-place mutation slipped through it. Also syncs the
telemetry schema page and adds the missing postgres round-trip assertion.
Pin the telemetry column semantics across all three emitter entry points,
add the cross-layer sampling snapshot, and reject extra_body on the
embedding and OCR paths instead of accepting it silently.
Wiki site synced across six pages (commit 4c8dc09 on the wiki repo) and
issue #2 answered with the shipping conditions for the downstream
workaround removal.
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.
Leaves the wiki-site sync, the issue #2 reply and the version bump
unticked -- those are external deliverables this repository cannot
self-certify, and the pre-merge review was right to flag their absence.
The migration doc is a standing constraint on library design, so an
outdated enum there states an outdated fact. B13's substance survives
the change -- GovDoc's zero was never the problem, the missing label
was -- but the row now names unavailable and the cache_hit-qualified
gap query alongside it.
The gate check forced operators to guess a per-call token size before
they could enable the TPM gate at all; est_tokens is now an optional
tuning override and effective_est_tokens() derives the reservation from
the provider quota. Reservation and settlement already read the same
derived value, so the deposit still nets to zero on both the success
path and the non-dead transient failure path.
The rest of _validate_gates is untouched, and the est_tokens field plus
its EST_TOKENS env key stay put for migration compatibility.
Five call sites (QuotaGate entry, RetryMW/EmbeddingClient success and
transient-failure settlement) now read effective_est_tokens() instead of
est_tokens. Success paths gain an unavailable branch that keeps delta at
zero once usage frames may be missing; it has no producer yet, so
behaviour is unchanged while the tpm>0 => est_tokens>0 gate still holds.
Task 1 of the est_tokens decoupling: capability only, no call site
touched, so library behaviour is unchanged word for word.
SourceConfig.effective_est_tokens() returns the explicit est_tokens when
set, otherwise tpm // 60 floored at 1, otherwise 0 when the TPM gate is
off. The divisor is scale free: any quota size yields the same in-flight
ceiling of roughly sixty calls, which is what makes the default
explainable where a fixed constant was not.
USAGE_SOURCES lands with the two assertions the design asks for, not as
a dead constant. test_usage_source_domain.py drives every production
point -- _resolve_usage, _resolve_embedding_usage, _merge and the three
TelemetryEmitter.emit_* helpers -- and asserts the output stays inside
the domain; it is a separate file because the assertion spans
transports, embedding and telemetry, and the innermost kernel test
should not depend on implementations. The second assertion pins the
opposite ruling: constructing LLMResponse with an out-of-domain value
must not raise, since a bare ValueError at a runtime construction point
falls outside the four error categories and would escape chat().
tpm > 0 with est_tokens = 0 is still rejected until Task 4, so the
derivation tests build the future-legal shape through a helper that
bypasses the constraint; the helper collapses back to _make_source once
the constraint is gone.
