C1 coherence floor: a deterministic verifier that runs on every
candidate surface produced by the truth path, before assignment to
ChatResponse.surface. Rejects illegal articulations and routes them
to a bounded disclosure string — admission control with a
deterministic fallback, not normalization.
Active rules (R1 deferred during ratification — see ADR):
R2_aux_neg_requires_verb — "<aux> not <wrong-POS>" rejected
R3_be_neg_requires_predicate — "<be> not <verb>" rejected
Fail-open on unknown POS, fail-closed on explicit wrong POS.
Cognition eval byte-identical (100/91.7/100/100).
Original bug class — "Light reveals truth, right?" → "Right does not
thought." — now routes to "I do not have a reviewed articulation for
that yet." with grounding_source=none, walk_surface preserving the
rejected candidate, and telemetry carrying R2_aux_neg_requires_verb.

`ChatRuntime.correct()` propagates a backward perturbation through the
session graph (per session/correction.py): each past turn whose output
versor has non-trivial CGA-alignment with the correction versor is
blended toward it (decayed by graph distance). The forward regen turn
that followed already emitted a TurnEvent — but the backward
perturbation itself was invisible to the telemetry sink.
ADR-0059 closes that gap with a discriminated event line.
- chat/telemetry.py — adds `serialize_correction_event` +
`format_correction_event_jsonl` emitting one JSONL line discriminated
by `"type": "correction"`. Payload: target_turn, records_count,
turns_skipped, turn_idxs_affected, max_delta_norm, mean_delta_norm,
SHA-256 correction_versor_digest, pack ids. No raw versor coordinates.
- chat/runtime.py — `_emit_correction_event` (mirrors
`_emit_turn_event`); called from `correct()` after the graph state
is updated but before the forward regen turn. No-op without sink.
- tests/test_correction_telemetry.py — 7 tests pin: no-op without
sink, emission with sink, payload shape (required keys + types +
ranges), SHA-256 digest shape, trust boundary (no versor
coordinates leaked), determinism (byte-identical lines across
runs), correction event and turn event coexist in the sink.
Trust boundary (per CLAUDE.md):
- Metadata-only: only L2 deltas + SHA-256 digest.
- No implicit wall-clock.
- Deterministic: same CorrectionResult → byte-identical line.
- Sink contract unchanged: `emit(line: str)`.
- `versor_condition < 1e-6` invariant: untouched (telemetry-only).
Verification: smoke 67 / runtime 19 / correction telemetry 7 — green.
Two thin layers closing the audit story end-to-end:
- core chat --show-verdicts prints format_verdict_summary(verdicts)
to stderr after each turn. Stdout stays clean for piped
consumers. Format is dense and terse; designed to skim, not
machine-parseable (the JSONL sink owns that contract).
- FanOutSink forwards every emitted line to N sinks in declaration
order. Fail-fast on first error — consistent with ADR-0040's
single-sink contract (audit failures surface). Composes with
any combination of JsonlFileSink / JsonlBufferSink / future
sinks.
Two formatters, one bundle: format_turn_event_jsonl (machine,
ADR-0040) and format_verdict_summary (operator, ADR-0041) both
consume the same TurnVerdicts. No risk of drift.
Summary format:
[identity=0.83 safety=ok ethics=VIOLATED:foo refusal=- hedge=YES]
Audit story now reads end-to-end:
- TurnVerdicts bundle (ADR-0039)
- Machine JSONL sink (ADR-0040)
- Fan-out + operator CLI (ADR-0041)
Files:
- chat/telemetry.py — FanOutSink dataclass, format_verdict_summary,
_format_verdict_short helper
- core/cli.py — --show-verdicts on chat subparser; cmd_chat prints
summary to stderr when set
- tests/test_telemetry_fanout_and_summary.py (new) — 13 tests
- docs/decisions/ADR-0041-cli-verdicts-and-fanout.md (new)
Verification:
- Combined pack-layer + telemetry suite: 212 green (was 199; +13)
- CLI suites unchanged: smoke 67, runtime 19, cognition 121
- core eval cognition: intent 100%, versor_closure 100% (baseline)
- Manual smoke: echo "light is" | core chat --show-verdicts prints
expected bracketed audit line to stderr alongside response.
