 `writeRunLog()` (`src/core/log.ts`) appends one JSON line per run — cost, tokens (run-wide and per bucket), findings, coverage notes, decision — so runs are auditable and cost/latency measurable later. The record deliberately excludes PR title and body text, keeping only `baseRef`/`headRef`, to avoid persisting secrets that might appear in author-controlled text [observed] (`log.ts:13-18`). Findings may quote changed source lines, but only content the review already publishes verbatim in the PR comment.
 
-Each successful reviewer pass may also return a bounded conclusion-only trace: up to three concrete checks and two unresolved questions, with each note capped at 240 characters. Trace parsing is deliberately fail-soft: malformed optional diagnostics are dropped while valid findings from the same response survive, so observability can never create a coverage gap. `runReview()` merges and de-duplicates valid notes per reviewer, sorts reviewer ids, caps both the stored roster and the complete decoded trace (6 KB), labels the result `unverified-model-diagnostics`, and attaches it to `CoordinatorOutput.reviewTrace` only after the decision pipeline finishes. `attachReviewTrace` strips any coordinator-authored value before attaching the engine-built trace; even a malformed injected coordinator value parses as absent rather than failing consolidation. The trace therefore never reaches coordination, verification, suppression, or decision logic. Because the GitHub comment already embeds the full coordinator output as durable state, downstream agents can recover the trace without adding visible review prose or storing raw transcripts and chain-of-thought. The same trace rides the run log for short-lived operational inspection [observed: `schema.ts` `ReviewerTraceNotesSchema`/`ReviewTraceSchema`/`ReviewerOutputSchema`; `review.ts` `mergeTraceNotes`/`buildReviewTrace`/`attachReviewTrace`; `render.ts` embeds the full review].
-
 Observability must never break a review, so both output sinks swallow their own errors: `safeLog` wraps `writeRunLog` and discards any write error [observed] (`review.ts:1269-1275`), and `appendStepSummary` is a no-op outside Actions and swallows append failures [observed] (`step-summary.ts:9-19`). A consequence worth stating: a missing or corrupt run-log entry is therefore **not** an error signal — the log's presence or absence proves nothing about whether the review succeeded.
 
 Finally, `publicFailureReason()` (`src/core/util.ts`) is the only failure text allowed into PR-facing comments [observed] (`util.ts:20-27`; used in `src/commands/ci.ts:176,365,575`). `run()` throws errors of the form `"Command failed: <cmd> <argv>\n<stderr>"`, which embed a subprocess's full command line, its stderr, and absolute runner paths — CI-internal detail of no use to a PR author and exactly what must not leak into an attacker-visible artifact. Those shapes collapse to a generic pointer at the workflow log; the tool's own argv/path-free messages pass through, since they are the actionable ones the fail-fast design means to surface. Every call site still writes the full reason to the job's stderr.

There is no side-channel database; the comment body is the state. Dismissed findings render in a collapsed `<details>` section, disjoint from the active list (a finding is never in both), keeping the main list clean while preserving a `by`/`reason` audit trail.
 
-The full review may contain an engine-owned `reviewTrace`. It is deliberately invisible Markdown state for machine consumers, not a human-facing finding or hidden chain-of-thought. Its schema caps both item count and length, and marks every note as `unverified-model-diagnostics`. Keeping it inside `review` rather than beside it is load-bearing: dismissal re-renders already pass `state.review` back through `renderMarkdown`, so the trace survives `/dismiss` and `/undismiss` without another reporter parameter or a second persistence path [observed: `schema.ts` `CoordinatorOutputSchema.reviewTrace`; `reporters/github.ts` `applyDismissal`; `render.ts` `renderMarkdown`].
-
 ## Review Result Cache
 
 The same durable comment state is the cache for automated CI reviews. `reviewInputHash` (`src/core/review-cache.ts`) hashes each scoped changed file's content from the materialized PR-head tree, a normalized patch (blob ids and hunk coordinates removed; deletion/mode information retained), and every stable input that can change the result: the engine package version, resolved prompts/config/models, PR title/body, selected agents and routing mode, and external context. It deliberately excludes the temporary trusted-config path and the base/head commit OIDs. A restack changes OIDs and may move hunk line numbers; if it leaves the actual review input byte-identical, CI reuses the complete `CoordinatorOutput` already embedded in the most recent author-verified reviewer comment instead of launching the agents again. Symlinks are hashed as link targets and never followed. A package release changes the key so upgraded review logic runs once. Legacy comments store one `inputHash`; aggregate comments store one per `ScopeReviewResult`, so an unchanged scope can hit independently while a changed sibling reruns.

 `--scope --post` posts under the derived marker `<rootTag>:<scope>`, taken from the ROOT config's tag via `scopedCommentTag(rootConfig.commentTag, scope)` [observed: `src/commands/review.ts:230`]. This is not a local convenience — it must match `ecr ci`'s per-scope derivation exactly, so a standalone local scope post and CI's per-scope post/clear/reconcile paths always target the identical comment. The schema ban on scope-level `commentTag` overrides (LLP 0006) is the only thing keeping the two derivations from ever diverging; relaxing that schema rule would silently break marker consistency between local and CI posts.
 
-## Deferred Review Posting
-
-`ecr review --save-review --repo owner/repo --pr N` separates the expensive model
-run from the outward-facing GitHub write without changing the review between them.
-After terminal preview it writes the exact verified `CoordinatorOutput` plus bounded
-feedback records to an owner-only, versioned artifact under
-`.expo-code-review/.runs/deferred/`. The artifact contains no credential. Saving is
-PR-only, requires an explicit repo, and is mutually exclusive with immediate
-`--post`; scopes and alternate config directories are rejected in v1 rather than
-silently producing an artifact the post command cannot faithfully reconstruct
-[observed: `src/commands/review.ts` `validateReviewArgs`,
-`writeDeferredReviewArtifact`].
-
-`ecr post-review --artifact P --repo owner/repo --pr N` performs no model call. It
-loads config from the local checkout (the terminal user remains the trust principal),
-strictly schema-validates and byte-caps the artifact, and requires four independent
-bindings before any GitHub write: artifact target equals the explicit argv repo/PR;
-the live PR head equals the reviewed 40-hex OID; the current comment tag,
-break-glass marker, and feedback policy hash to the stored posting-policy
-fingerprint; and the live break-glass check returns false. A break-glass API error
-fails closed on this deferred path. Only then does it pass the stored review through
-the ordinary `GitHubReporter`, preserving the single-comment lifecycle, dismissal
-state, hidden review trace, links, pins, and feedback merge [observed:
-`src/commands/post-review.ts`, `src/core/deferred-review.ts`].
-
-The explicit repo/PR is deliberately repeated at post time. An artifact is data, not
-authority: even a locally replaced artifact cannot redirect a generic “post this”
-command to another PR. Head and policy drift require a fresh preview instead of
-publishing stale findings or rendering them under rules the model run never saw.
