Field counts come from inspect, not memory: record_llm_call takes 36
parameters, COLUMNS has 36 entries, the physical table has 37.
- README: capability table says 36 fields and names the three row kinds;
new section covers reading call_stats, the five SQL migration items,
the attribution query and the storage-side upgrade
- README/.env.example/ARCHITECTURE: error_body follows the summarize_body
limit and the structured-exhaustion error carries its own bounded
explanation, so neither is inside PGW_TELEMETRY_TEXT_CAP coverage
- ARCHITECTURE 7.8: the ten columns with per-column semantics, the I3/I4
invariants, operation versus exc.operation, and the assembly gate
- CHANGELOG: unreleased section listing the four public changes and what
downstream must do, in particular counting failures by event_kind and
the assembly-time error for custom recorders
- schemas/llm-calls: the ten columns plus a three-row-kind section
- metrics/call-telemetry-coverage: 1.3.5 coverage contract, real live
baselines left unfilled rather than stating a fake percentage
Validation record records the T4 evidence: mechanical migration red then
green, the four PG acceptance cases, the seven-item mutation matrix with
all seven killed and the copy restored to an identical digest, plus the
PYTHONPATH pitfall that made the first mutation round silently test the
original source.
Version numbers and release steps are deliberately untouched.
Grow the telemetry contract from 26 to 36 fields and give every logical
call a failure terminal row, so SQL can finally answer "how many calls
failed" and "why did the whole pool die".
Schema and port move together with the emitter writes in one commit:
splitting them would ship columns that nothing populates.
- schema: append 10 nullable columns (scope, operation, logical_call_id,
event_kind, http_status_code, error_type, cause_type, error_body,
attempts, total_latency_ms) to all five definition sites in one order
- ports: 10 keyword-only parameters without defaults; the protocol
signature is now the single source the assembly gate derives from
- emitter: take domain exception objects instead of pre-flattened text
and pin down the diagnostics in one helper; a relabelled 503 stays
503 and success rows leave all five columns NULL
- emitter: reject recorders whose record_llm_call cannot accept the
current field shape at assembly time, since _record would otherwise
swallow the TypeError and drop every row while calls keep succeeding
- clients: write at most one terminal row per logical call through a
single shared exit, deduplicated by the call context; TelemetryMW
stops writing terminals so the two sites cannot double count
- clients: cancellation stays best effort and propagates, non-domain
exceptions get no terminal row and keep their classification
- transports: give _status_to_error an explicit operation and fix the
historically mislabelled embedding HTTP failures
- structured: promote the bounded error formatter so the reask feedback
and the terminal explanation share one set of limits
Terminal rows carry no cost and no tokens, so cost aggregation is
unchanged; failure counts must now filter on event_kind.
