# pr-138: ADR 046 follow-up — Status flip + issue backfill + project-status sync

## Summary

ADR 046 (merged in PR #135, 2026-04-28) had three follow-up items in §Issue Sequence.
This PR closes that loop: flips ADR 046 from `Status: Proposed` to
`Status: Accepted`, backfills the §Issue Sequence placeholder with the real issue
numbers (#136 OTEL core setup, #137 Langfuse opt-in recipe), and adds the
corresponding row to `.claude/rules/project-status.md` Recent Major Changes.

## Review Rounds

> Each round lists every surfaced point as `R{n}.{m}` with severity, plus
> a one-line *Disposition* showing how that point was resolved (commit hash or
> rationale). This is the traceability requirement per prior round ICs.

### Round 1 — Codex cross-review (read-only)
- Reviewer: `codex exec --skip-git-repo-check --sandbox read-only` (default model)
- Trigger: Tier A change set (`docs/history/**`, `.claude/rules/**`)

| Point | Severity | Surface | Disposition |
|-------|----------|---------|-------------|
| R1.1 | BLOCKER | Korean review-angle labels in review-angle heading at `docs/ai/shared/governor-review-log/README.md:66` (pre-existing, surfaced when this PR touched the file) | `a287770 review-fix(R1.1): translate Korean review-angle labels in governor-review-log README template` |
| R1.2 | MINOR | Angle-bracket template placeholders in README prompt-template section (README:52-64) may trigger a naive all-file placeholder gate | Resolved by design: the leakage gate explicitly exempts the README prompt-template section (only the Index row is checked); no file change needed |

- Final Verdict: merge-ready (after R1.1 fix commit)
- Fix commits introduced for this round: `a287770 review-fix(R1.1): translate Korean review-angle labels in governor-review-log README template`

### Round 2 — Codex re-review after R1.1 fix
- Reviewer: `codex exec --skip-git-repo-check --sandbox read-only` (default model)
- Trigger: BLOCKER in Round 1

| Point | Severity | Surface | Disposition |
|-------|----------|---------|-------------|
| (none) | — | README:66 Korean confirmed absent; remaining Korean in project-status.md is allowlisted escape-token vocabulary | — |

- Final Verdict: merge-ready
- Fix commits: (none)

## R-points Closure Table

| Source | R-point | Closure | Note |
|---|---|---|---|
| Round 1 | R1.1: Korean review-angle labels in README template | Fixed | Labels were translated in `a287770`. |
| Round 1 | R1.2: angle-bracket placeholders may trigger naive gate | Rejected | Existing leakage gate explicitly exempts the README prompt-template section. |
| Round 2 | Post-R1.1 re-review | Fixed | Round 2 reported no new findings and a merge-ready verdict. |

## Inherited Constraints

- Carries forward PR #135's IC stack (no new ICs introduced by this PR)
- Tier 1 Language Policy: this entry, ADR diff, and project-status diff are English-only
- Backfill discipline: placeholder tokens replaced with real GitHub issue numbers
  in every consumer (ADR §Issue Sequence L216 + project-status row)
- No `Co-Authored-By: Claude` or "Generated with Claude Code" in any artefact

## Self-Application Proof

> Per `docs/ai/shared/governor-review-log/README.md` §Entry shape, this section
> requires canonical output of `/review-architecture` and `/sync-guidelines`
> on the PR's own changed surface, plus grep-based mechanical checks.

### `/review-architecture` (run on this PR's diff)

```
Scope: docs/history/046-otel-core-langfuse-recipe-prompt-domain-defer.md,
       .claude/rules/project-status.md,
       docs/ai/shared/governor-review-log/pr-138-adr-046-followup.md,
       docs/ai/shared/governor-review-log/README.md
Sources Loaded: AGENTS.md §Language Policy, docs/ai/shared/architecture-review-checklist.md,
                governor-paths.md §1D drift-checklist
Findings: none (§1-9 checklist categories N/A to doc-only changes; Language Policy: 0 violations
          per tools/check_language_policy.py across 164 files)
Drift Candidates: none
Next Actions: none
Completion State: Pass
Sync Required: false
```

### `/sync-guidelines` (closure run after /review-architecture)

```
Mode: review follow-up
Input Drift Candidates: none
project-dna: Unchanged (no architectural pattern or code-layer changes)
AUTO-FIX: none
REVIEW: none
Remaining: none
Next Actions: none — gate closed
```

### Mechanical checks (run before merge)

```bash
ADR=docs/history/046-otel-core-langfuse-recipe-prompt-domain-defer.md
PS=.claude/rules/project-status.md
README=docs/ai/shared/governor-review-log/README.md

grep -F "Status: Accepted" "$ADR"
! grep -q "Backfill actual issue numbers" "$ADR"
grep -F "#136" "$ADR"
grep -F "#137" "$ADR"
! grep -E '#74-A|#74-B' "$PS"
grep -F "#136" "$PS"
grep -F "#137" "$PS"
gh issue view 136 --json state | jq -r '.state'   # expected: OPEN
gh issue view 137 --json state | jq -r '.state'   # expected: OPEN
```

Placeholder-leakage gate: run the gate command from `plan §Verification Step 2`
against ADR + project-status + this log file. The gate regex is omitted here
to avoid a self-referential false positive (a regex pattern string in a code
block would trigger a regex that matches that same pattern). The gate command
is canonical in the plan file and executed by the author before merge.

README Index row check:
```bash
INDEX_ROW=$(awk '/^## Index/{flag=1; next} flag && /^\| #/{print}' "$README" \
  | grep -F "pr-138-adr-046-followup.md")
test -n "$INDEX_ROW"
```
