# Peer Review — llm-dev-v1.3.0 Release Candidate / Gemini

## Preamble — environment attestation

- `git branch --show-current` → `frameworks/llm-dev-v1.3`
- `git rev-parse HEAD` → `1339449420ed3ef285af833db7dc354b5bf8b085`
- Fix-pass chain verified against `review-board/v1.3.0-spec-verdict-response.md`:
  commit SHAs `ca5701a / c0e0ae4 / 73ee66a / dc84b45 / 6f8f83e / 053d427 /
  3564b75 / 2dfe769` present on branch.
- `bash scripts/verify-all.sh` → `verify-all: PASSED` (11/11 green + 4
  fixture regressions). Direct-run, re-executed at review start.
- Codex-family v1.3.0 verdict file not present on disk at review time
  (`git ls-files frameworks/llm-dev-v1/review-board/ | grep v1.3.0-review-codex`
  returns empty); proceeding independently per dispatch.

## 1. Completeness check

All expected sections present in the release candidate:

- CHANGELOG.md v1.3.0 entry at `frameworks/llm-dev-v1/CHANGELOG.md:6-91`
  (must-ship / should-ship / deferred tables + Additional v1.3.1 deferrals
  + Conformance suite line); ROADMAP.md bump; schema enum widening to
  include `"1.3.0"`.
- All 6 focal templates (01, 02, 06, 07, 12, 15) plus 03/05/08/13/14/19
  carry v1.3 diffs with BEGIN/END markers intact (counted 1 BEGIN + 1 END
  per template across all 10 edited templates).
- `docs/retros/v1.3-build-retro.md` frontmatter `status: completed` +
  `date_closed: 2026-04-17` (closes CLAUDE-MIN-5 as disposed).
- Cross-references in walkthroughs resolve: all five script/template
  references in `examples/walkthrough-mini-deliverable.md` exist;
  v1.2 walkthroughs (`walkthrough-triage.md`,
  `walkthrough-validation-run.md`) reference only `17-triage.md` /
  `18-validation-run.md` (both present).

No gap in section completeness. Gaps found are in content quality
(see §4 and §5 below), not in presence.

## 2. Template-fidelity cross-reference

| Template | BEGIN/END present? | Frontmatter tokens ⇔ body | Halt conditions complete | v1.3 additions coherent |
|----------|---------------------|----------------------------|---------------------------|--------------------------|
| 01-worker-session-contract.md | yes (L42 / L177) | yes (22 body tokens all declared; `FINAL_REPORT_SCHEMA` exempted in verify-frontmatter.sh:47) | catalog 17 role entries; skip-failing-activation (L56-65), implicit logs-path (L79-93), commit-split-by-role (L125-146), spec-vs-impl divergence (L208-219) all additive and coherent | yes — but **pre-existing duplicate `### Verifier` section** at L232+L266 (divergent bullet content: L232-242 has 4 items incl. scope-lock; L266-269 has 2 items). Predates v1.3, but v1.3's heavy edits here make this the moment to reconcile (see MIN). |
| 02-phase-dispatch-handoff.md | yes (L159 / L262) | yes | extended via `<HALT_CATALOG_BLOCK>` token which the orchestrator fills from Template 01's catalog | yes — orchestrator preflight (L41-71), provider-capacity fall-through (L73-110), parallel-execution context (L112-130), stdout-to-file redirect (L132-157) all coherent with schema additions |
| 06-meta-consolidator.md | yes (L26 / L340) | yes | n/a (meta-consolidator halt conds inherit from 01) | v1.3 `consolidation_mode: author-direct-with-external-lens` variant added |
| 07-final-approval-gate.md | yes (L367 / L506) | yes | n/a | scope-lock code-path vs doc-prose split added; grep-code-only.sh referenced |
| 12-spec-author.md | yes (L27 / L209) | yes (15 body tokens all declared) | spec-author halts extended with § 12 Helper-divergence disclosure (v1.3) + § 11 anchor omission (v1.2); both reachable | yes — § 12 content is self-contained; table example rows demonstrate both Extend / Diverge modes |
| 13-implementation-author.md | yes (L754 / L854) | yes | § 11 Contract-enumeration anchor-coverage final-report row consumed from spec (v1.3 §2.2) | yes |
| 14-fix-summary.md | yes (L885 / L1002) | yes | smoke-check re-baseline checkbox (v1.3 §5.6) added | yes |
| 15-verifier.md | yes (L30 / L219) | yes (8 body tokens all declared; `FINAL_REPORT_SCHEMA` exempt) | extensions: canonical loader-swap (L72-113) + `--cache-clear` (v1.3, L115-127) + provider-side capacity (v1.3, L195-205) + P13 self-review D.5 gap (v1.3, L206-217) | yes |
| 08-retrospective.md | yes (L1028 / L1176) | yes | n/a | 7-subsection framework-learnings required (v1.3 §5.9) |
| 19-review-board-product.md | yes (L1209 / L1445) | yes | file-existence attestation (v1.3) | yes |

Summary: all 10 edited templates have balanced BEGIN/END markers,
frontmatter ⇔ body token agreement (as confirmed by
`verify-frontmatter.sh` OK on the suite), and halt-condition extensions
that compose cleanly. Only finding in this section is the pre-existing
duplicate Verifier entry in Template 01 — filed as MIN below because
it's not a v1.3 introduction.

## 3. Walkthrough coverage

| Walkthrough | File | v1.3 compat | Notes |
|-------------|------|-------------|-------|
| Mini-deliverable | `examples/walkthrough-mini-deliverable.md` | byte-unchanged (11480 bytes @ 1a1d9e5 = 11480 bytes @ HEAD); all 5 referenced scripts/templates still exist | **byte-unchanged claim verified** via `git show <sha>:<path> \| wc -c` on the first-stable v1.0 commit (`1a1d9e5`) vs HEAD. Semantic check: walkthrough uses `claude-opus: spec-author / implementation-author / fix-author` with non-overlapping review roles — does not trip v1.3 P13. |
| Triage | `examples/walkthrough-triage.md` | references `17-triage.md` (exists) | clean |
| Validation-run | `examples/walkthrough-validation-run.md` | references `18-validation-run.md` (exists) | clean |
| User-facing | `examples/walkthrough-user-facing.md` | references `19-review-board-product.md` (exists) | clean |

All four walkthroughs semantically valid under v1.3.

## 4. Conformance-suite audit

| # | Check | Real coverage? | Evidence |
|---|-------|----------------|----------|
| 1 | verify-schema.sh | yes — `check-jsonschema` validates both example manifests against deliverable-manifest.schema.yaml; hard-fails when validator absent (v1.1.1 C-5 closure). | direct-run: script at `scripts/verify-schema.sh`; verify-all.sh output "2 manifests validated". |
| 2 | verify-tokens.sh | yes — body-tokens-vs-frontmatter diff + pseudo-token scan with backtick/fence exemption (v1.3 §5.1 / CLAUDE-MIN-2). Non-zero rc on mismatch. | direct-run: `bash scripts/verify-tokens.sh` → OK. |
| 3 | verify-frontmatter.sh | yes — per-template diff. `FINAL_REPORT_SCHEMA` explicitly exempted (scripts/verify-frontmatter.sh:47). | direct-run: OK. |
| 4 | verify-p3.sh | yes — v1.2 adversarial-family invariant + v1.3 P13 + capability × role + reviewer_family_substitutes + evidence-cap default. Version-gate at `:279` guards v1.3 checks. | direct-run: triggered v1.3 P13 against synthetic v1.3 manifest with codex C+D.2+D.3+D.5 → rc=1; same against v1.0 → passes (backward-compat intact). |
| 5 | verify-pre-a.sh | yes (v1.1 contract; not v1.3-edited). | direct-run: OK. |
| 6 | verify-gate-categories.sh | yes (v1.0 contract). | direct-run: OK. |
| 7 | verify-artifact-paths.sh | yes (v1.0 contract). Build plan 5.11 promised globbing extension for `scope.allowed_path_patterns`; **deferred to v1.4 per disposition table SF-3**, script contract unchanged. | direct-run: OK. |
| 8 | verify-portability.sh | yes — grep + awk exemption filter. Minor concern: shellcheck-ignored `host_patterns` variable at L37 is documentation-only and never referenced; the real grep at L43 uses a simpler pattern list (no negative-lookahead). Intentional per comment; not a defect. | direct-run: OK. |
| 9 | verify-circuit-breaker.sh | yes (v1.2 contract; not v1.3-edited). | direct-run: OK. |
| 10 | verify-shellcheck.sh | yes — runs shellcheck on 21 scripts at severity=warning. Soft-skip (exit 2) if shellcheck absent. | direct-run: "21 scripts clean at severity=warning". |
| 11 | verify-version-bump.sh | yes — CHANGELOG latest-released extraction + enum membership check + CLAUDE-MIN-14 historical preservation loop. | direct-run: "CHANGELOG latest '1.3.0' ∈ enum [...]; all 5 historical version(s) preserved". |
| Fixture A | verify-d6-gate (fixture) | yes — parses `examples/d6-gate-fixture.md` end-to-end (10 rows). | direct-run: OK. |
| Fixture B | check-handoff.sh (example-manifest.yaml) | yes — triggers Checks A + B against a v1.3 manifest declaration | direct-run: OK on clean fixture; verified FAIL on a synthetic v1.3 fixture with `pydantic` conflict + C=D.2 overlap. |
| Fixture C | check-handoff.sh (example-user-facing-manifest.yaml) | yes — second fixture exercises `sibling_deliverable_ids[]` NOTE path. | direct-run: OK. |
| Fixture D | **post-rebase-tracker-restamp.sh (fixture)** | **NO — toothless. See GEM-P-1.** The fixture at `examples/tracker-rebase-fixture.md` contains only `deadbeefdeadbeefdeadbeefdeadbeefdeadbeef` + `deadbeef` SHAs. The script's control flow on this input exits via `git cat-file -e <sha>^{commit}` returning non-zero → `continue` at script line 91. The **Python re.sub substitution block** at lines 130-154 that was the entire BLK-3 / SF-7 / SF-13 fix **is never executed**. A reverted sed-version script returns identical `rewrites=0 unresolved=0` output on the same fixture. | direct-run: see reproduction in GEM-P-1. |

**10 real-coverage checks + 1 toothless fixture**, against the
release's self-claim of "11/11 green + 4 fixture regressions".

## 5. Issues found

### Blocking (Critical)

| ID | Description | Location | Evidence | Reproduction | Suggested action |
|----|-------------|----------|----------|--------------|------------------|
| GEM-P-1 | **Toothless regression fixture for CLAUDE-BLK-3 / CLAUDE-SF-7 / CLAUDE-SF-13.** `examples/tracker-rebase-fixture.md` uses deliberately-unreachable SHAs (`deadbeef...`). The script short-circuits at `post-rebase-tracker-restamp.sh:87-91` (`git cat-file -e <sha>^{commit}` fails → `continue`) before reaching the Python `re.sub` substitution block at `:130-154`. The entire v1.3 fix-path (cross-platform word-boundary substitution, sha1 pre/post hash comparison, counting-masks-failure gate) is **never executed by the conformance suite**. Re-introducing the broken BSD `sed -i.bak "s/\b${sha}\b/..."` version would produce identical `rewrites=0 unresolved=0` output on this fixture. The fix-pass response doc claims "The new `examples/tracker-rebase-fixture.md` + wiring exercises the BLK-3 fix-path in the conformance suite on every run" (response doc line 46); it does not — the fixture exercises the `continue` fast-path, not the fix-path. | `frameworks/llm-dev-v1/examples/tracker-rebase-fixture.md:1-34` (fixture); `frameworks/llm-dev-v1/scripts/post-rebase-tracker-restamp.sh:82-91` (continue branches); `frameworks/llm-dev-v1/scripts/verify-all.sh:87-102` (wiring) | direct-run | **A.** Run the bundled fixture on current HEAD: `bash scripts/verify-all.sh` final line reports `post-rebase-tracker-restamp: rewrites=0 unresolved=0` — confirms fast-path taken. **B.** Swap the script body to a no-op (keep only the `continue` paths + final echo) and re-run verify-all → same output, same PASS. **C.** Proof the fix-path works OUTSIDE the fixture: synthesize two empty-file commits with a shared subject (`mkdir /tmp/rt; cd /tmp/rt; git init -q; git commit -q --allow-empty -m seed; echo x>f; git add f; git -c user.email=t@t -c user.name=T commit -q -m 'shared subject'; OLD=$(git rev-parse HEAD); git reset --hard HEAD~1 -q; echo y>f; git add f; git -c user.email=t@t -c user.name=T commit -q -m 'shared subject'; printf '| B | %s |\n' "$OLD" > t.md; bash /Users/jonathanoh/johnny-os/frameworks/llm-dev-v1/scripts/post-rebase-tracker-restamp.sh --tracker t.md`) — I did this; script correctly rewrote 2 occurrences. Proves substitution works when invoked directly, but the **fixture doesn't reach it**. | Replace the deadbeef-based fixture with a self-contained two-commit git-rebase scenario. Options: (a) construct the rebase in `scripts/verify-all.sh` before invoking the script (mktemp repo, two commits sharing subject, synthetic tracker citing the pre-rebase SHA) and assert post-run diff is non-empty; (b) add a second fixture that carries a SHA known to be reachable from the bundle's own git history and a companion subject-sharing commit; (c) inject a Python unit-test harness that imports and exercises the `re.sub` substitution block directly. Option (a) is the smallest change and matches the pattern used by the BLK-3 fix commit's ad-hoc test per response doc line 43. |

### Should-fix (Major)

| ID | Description | Location | Evidence | Reproduction | Suggested action |
|----|-------------|----------|----------|--------------|------------------|
| GEM-P-SF-1 | **`reviewer_family_substitutes` v1.3 validation fires on pre-v1.3 manifests — residual backward-compat leak of CLAUDE-BLK-1 class.** CLAUDE-BLK-1's fix-pass (commit `ca5701a`) correctly version-gated the P13 self-review, capability × role, and verifier-test_runner checks at `verify-p3.sh:279`. But the `reviewer_family_substitutes` validation at `:469-520` sits **outside** that `if _version_tuple(manifest_version) >= (1, 3, 0):` block (the block closes at :461; the next indented `if` at :499 is the v1.2-gated adversarial-substitute rule, not the v1.3 "primary not referenced" check at :488-496). A pre-v1.3 manifest that declares `reviewer_family_substitutes[]` with a primary not listed in `model_assignments` hits the v1.3 error "(v1.3 reviewer_family_substitutes)" despite the field being additive + optional per CHANGELOG "non-goals held". This is narrower in impact than BLK-1/2 because pre-v1.3 schemas don't advertise the field, but an adopter pinning `manifest_version: "1.0.0"` while experimenting with v1.3 opt-in features will hit it. | `frameworks/llm-dev-v1/scripts/verify-p3.sh:469-496` | direct-run | Create `/tmp/v10_subs.yaml` with `manifest_version: "1.0.0"`, a minimal `model_assignments`, and `reviewer_family_substitutes: [{primary: not-assigned-anywhere, substitute: claude-opus, lens: peer}]`. Run `bash scripts/verify-p3.sh --manifest /tmp/v10_subs.yaml` → stderr contains `reviewer_family_substitutes[0] primary 'not-assigned-anywhere' is not assigned to any phase in model_assignments; substitute declaration has no effect (v1.3 reviewer_family_substitutes).`; rc=1. | Wrap the three `reviewer_family_substitutes` validations (`primary == substitute`, `primary not referenced`, and the v1.2-gated adversarial-substitute check) in an outer `if _version_tuple(manifest_version) >= (1, 3, 0):` — mirrors the pattern ca5701a established for P13/capability-cross-check. Alternative (smaller change): only gate the "primary not referenced" soft-check (which fires on structural declaration issues); the equality check `primary == substitute` could be considered pure schema hygiene that applies across versions, but CHANGELOG row 1.4 calls this a v1.3 schema field — the field itself is v1.3+, so the whole block should gate on `>= (1, 3, 0)`. |
| GEM-P-SF-2 | **verify-gate-commands.sh WARNING banner displays malformed text — fix-pass defect in CLAUDE-SF-4 partial close.** Commit `053d427` added the stderr warning banner at `verify-gate-commands.sh:64-71` using `cat >&2 <<BANNER` (unquoted heredoc delimiter). The body contains `bash \`eval\`` on L67 — bash expands backticks as command substitution inside unquoted heredocs. The `\`eval\`` runs `eval` with no arguments (a no-op that returns empty), so the rendered banner shows `bash  ` (two spaces) instead of `bash \`eval\``. The adopter sees "via the shell (bash ). Only run against a manifest you trust." — confusing, and weakens the operational clarity the SF-4 fix was introducing. The TOCTOU mktemp replacement in the same commit is correct; this is narrowly the banner text. | `frameworks/llm-dev-v1/scripts/verify-gate-commands.sh:64-71` | direct-run | `bash scripts/verify-gate-commands.sh --manifest manifest/example-manifest.yaml 2>&1 \| head -3`. Observed output line 3: `         via the shell (bash ). Only run against a manifest you trust.` (note the double-space between `bash` and `).`). Expected: `via the shell (bash \`eval\`)`. | Change `<<BANNER` to `<<'BANNER'` (single-quoted delimiter suppresses command substitution + variable expansion inside the heredoc body). This requires moving the `Manifest: $manifest` interpolation to a separate printf / echo call since the quoted heredoc also suppresses `$manifest` expansion. Minimal diff: `cat >&2 <<'BANNER'` for the boilerplate warning, then `echo "         Manifest: $manifest" >&2; echo "==========...==========" >&2` for the manifest-line + closing rule. |

### Minor

| ID | Description | Location | Evidence | Suggested action |
|----|-------------|----------|----------|------------------|
| GEM-P-MIN-1 | Template 01 `### Verifier` role entry appears twice (L232 at "Verifier (phase D.5)" with 4 halt items; L266 at "Verifier (D.5)" with 2 items). Predates v1.3, but v1.3's commits b1b79db + 287fd8a + 5b549f7 heavily touched Template 01 and this moment is the natural time to reconcile. A fresh adopter inlining the halt-condition catalog via `<HALT_CATALOG_BLOCK>` in Template 02 would have to pick one of the two sections ambiguously; the v1.3 generator-spec updates (CLAUDE-MIN-6, deferred to v1.4) will inherit this inconsistency. | `frameworks/llm-dev-v1/templates/01-worker-session-contract.md:232-242`, `:266-269` | static-inspection (diff-history confirms both sections existed pre-v1.3) | Merge the two Verifier entries under a single `### Verifier (phase D.5)` heading. Preserve the stricter (L232) 4-item list; the L266 2-item list duplicates 2 of its 4 items. |
| GEM-P-MIN-2 | Template 12's output scaffold uses nested ```markdown / ```text fences (scaffold opens `markdown` fence at :98, diagrams open `text` fences at :122 and :127 inside the scaffold body, scaffold closes on :187). Rendered markdown readers close the outer fence at the first inner ``` marker, losing the structure for any operator who pastes the scaffold into a richly-rendered surface. Pre-v1.3 shape; v1.3 added § 12 Helper-divergence disclosure as more table rows inside the same outer scaffold, so the mis-nesting has grown in content value. Not a correctness defect for copy-paste adopters (plain-text copy works); presentation-surface only. | `frameworks/llm-dev-v1/templates/12-spec-author.md:98-187` | static-inspection | Either (a) replace the inner `text` fences with indented code blocks (4-space leading) so the outer `markdown` fence stays intact; or (b) emit the scaffold as a non-fenced example prefaced with "Example shape (not a code fence — plain markdown below)." Option (a) is smaller. |
| GEM-P-MIN-3 | `grep-code-only.sh` excludes `.md`, `docs/`, `README*`, `CHANGELOG*`, `ROADMAP*`, `PROVENANCE*`, `review-board/`, `examples/*.md` — but does NOT exclude the `scripts/` directory where prose comments inside `.sh` files may themselves contain documentation of forbidden-symbol patterns (e.g., `check-handoff.sh:8-11` documents `pydantic` in comments as part of its rule-description). The intent of the helper per its banner is "scan CODE only, ignore prose"; a docstring inside a code file is still prose. In practice adopters will use this for their own code paths, not the framework's own scripts, but if the bundled verify scripts are themselves the scope-lock target (as they could be for adopter forks vendoring the framework under their `scripts/`), false positives are possible. | `frameworks/llm-dev-v1/scripts/grep-code-only.sh:41-53` | static-inspection | Document the "comments inside code files remain in scope" limit in the script header, OR add `--exclude-docstrings` option that invokes a simple pre-filter (awk strips `^#` lines and `"""..."""` Python docstrings before git-grep). Minimal change: header comment. Deeper change: awk/sed pre-filter. |
| GEM-P-MIN-4 | `verify-gate-commands.sh` is documented as adopter-side and not wired into `verify-all.sh` at runtime (correctly gated per SF-4 partial close). But the SF-4 deferral note only lives in CHANGELOG's "Additional v1.3.1 deferrals" section (CHANGELOG:76) and nowhere inside the script or its output. An adopter who runs the script directly sees the warning banner but no pointer to "this is expected to be fixture-wired in v1.3.1"; they may assume the adopter-side invocation is the permanent design. | `frameworks/llm-dev-v1/scripts/verify-gate-commands.sh:17-23` | static-inspection | Append a single line to the header docstring: "v1.3: fixture-mode wiring into verify-all.sh deferred to v1.3.1 — see CHANGELOG Additional v1.3.1 deferrals." |

### Reachability gaps (rule-reachability audit)

Each new v1.3 validation-layer rule has at least one citable trigger:

| v1.3 rule | Triggering citation |
|-----------|---------------------|
| P13 self-review detection | `scripts/verify-p3.sh:338-403` — direct-run triggered on synthetic v1.3 manifest with codex C+D.2+D.3+D.5 → rc=1 with explicit `P13 self-review overlap` error. |
| Capability × role cross-check | `scripts/verify-p3.sh:289-311` — also reachable; would fire on a manifest with e.g. `codex: implementation-author` + `cli_capability_matrix.codex.test_runner: false`. |
| Scope-lock split (code-path vs doc-prose) | `scripts/grep-code-only.sh` (v1.3) + Template 07 reference. Reachable as helper; Template 07's gate-assertion prose explicitly directs D.6 reviewers to invoke it. |
| Framework-default evidence cap | `scripts/verify-p3.sh:324-325` — reachable in verifier-role branch. |
| fallback_models escalation ladder | `scripts/model-availability-probe.sh` (mechanical) + `framework.md § P3` (doctrine); Template 02:73-110 (orchestrator preflight) + Template 15:195-205 (worker halt). |
| Version-gating on v1.3 checks | `scripts/verify-p3.sh:279` + `scripts/check-handoff.sh:78`; direct-run showed v1.0 manifest passing both checks, v1.3 manifest correctly triggering P13. |

No v1.3 rule is prose-only without a citable mechanical or procedural
trigger. **Caveat**: GEM-P-SF-1 reveals that the version-gate coverage is
not total — `reviewer_family_substitutes` validation partially escapes
the v1.3 gate. That is a regression finding, not a reachability gap
(the rule fires; it just fires against the wrong manifest versions).

### Test-blessed divergence audit

`git grep -nE "does NOT raise|accept.*despite|keeps working|TODO.*spec|XXX|HACK|FIXME|assertNotRaises|pytest\.mark\.xfail|skip.*spec"` across `frameworks/llm-dev-v1/examples/` + `frameworks/llm-dev-v1/manifest/` returns **zero hits**. Matches elsewhere in the framework (Templates 03 + 05, v1.3-build-plan.md, historical review-board files) are the audit's own regex description prose, not example-manifest / fixture content. No latent defects blessed.

## 6. Positive observations

- **Version-gating pattern is exemplary where applied.** The fix-pass on BLK-1 / BLK-2 follows the v1.2 `_version_tuple` pattern verbatim, documented with inline commentary citing the closed CLAUDE-IDs. The refactor is minimal (three conditional wrappers, two in verify-p3, one in check-handoff) and localized. The mechanism is re-usable for future v1.N gates.
- **Python `re.sub` replacement on `post-rebase-tracker-restamp.sh`** is correctly cross-platform — I directly reproduced a real rebase scenario (two empty-file commits with shared subjects) and the script rewrote 2 SHA occurrences cleanly. The sha1 hash pre/post comparison correctly distinguishes "substitution found match + changed file" from "regex found no match". The script alone is solid; only the conformance-suite fixture that exercises it is weak.
- **Backtick / fence exemption in `verify-tokens.sh`** (v1.3 §5.1) closes a real recurrence: the pseudo-token scanner at :142-164 correctly preserves the original line for reporting while stripping inline backticked regions from the detection string, and toggles a fence-state counter to skip code-block bodies. Pattern is both surgical and well-commented.
- **`verify-version-bump.sh` CLAUDE-MIN-14 historical-preservation loop** closes a subtle class of backward-compat defect in a single concise block (:80-97). The fix-pass caught a real "accidental prune" failure mode that the original check didn't cover.
- **`reviewer_family_substitutes` structural checks + `sibling_deliverable_ids[]: maxItems: 2`** represent mature schema-design discipline: new fields ship with validation AND with explicit maxItems bounds when n ≥ 3 is unproven. The defensive truncation on the check-handoff NOTE (first 5 + "... and N more") is a nice touch against hypothetical adopter forks that raise the cap.
- **Byte-identical v1.0.0 walkthrough across four releases** is a strong backward-compat signal. SHA-tracked sizes match; no whitespace-noise drift over five versions.
- **Fix-pass disposition discipline.** The response doc in `review-board/v1.3.0-spec-verdict-response.md` assigns every finding a disposition (closed / deferred / rejected) with fix SHA or rationale. Zero "silently dropped" findings. The deferrals are named with explicit target releases (v1.3.1, v1.4). This is the clearest fix-pass I've observed.

## 7. Verdict

**Needs Fixes.**

One blocking-grade Peer finding (GEM-P-1 — toothless regression
fixture). One partial-close defect introduced by the fix-pass itself
(GEM-P-SF-1 — reviewer_family_substitutes version-gate leak) that
replicates the exact backward-compat regression class the fix-pass
was closing for P13 / capability-cross-check. One cosmetic fix-pass
defect in the same SF-4 commit (GEM-P-SF-2 — BANNER heredoc
expansion). Four minors.

GEM-P-1 is classified blocker — not merge-blocker — because it is a
conformance-suite coverage defect, not a correctness defect in the
shipped code: the post-rebase-tracker-restamp.sh script itself works
correctly cross-platform (I reproduced a real rebase and the script
rewrote SHAs correctly). The blocker is that the conformance suite
claims to exercise the fix-path and doesn't. A future regression
(e.g., someone re-introducing the broken `sed -i.bak "s/\b..."` call
while keeping the `git cat-file` short-circuit intact) would pass the
fixture silently. The response doc explicitly claims the fixture
"exercises the BLK-3 fix-path in the conformance suite on every run"
(response doc line 46) — that claim is not true of the current
fixture shape.

Suggested fix-pass budget: 1 commit for GEM-P-1 (replace
deadbeef-fixture with a synthesized two-commit rebase scenario +
non-empty-diff assertion, ~30 lines of bash in verify-all.sh or a new
harness file); 1 commit for GEM-P-SF-1 (wrap `reviewer_family_substitutes`
validation in version gate, ~5-line diff); 1 commit for GEM-P-SF-2
(heredoc delimiter fix + manifest-line extraction, ~3-line diff); 1
commit for the minor sweep.

Closing GEM-P-1, GEM-P-SF-1, and GEM-P-SF-2 in a focused fix-pass
returns the release to Approve candidacy from the Peer lens. The
release's structural quality (34/34 scope rows, atomic commit
discipline, backward-compat intact at schema level, direct-run
evidence in 10/11 real conformance checks) is high; the residual
issues are at the same mechanization-vs-prose boundary Claude-family
adjudication already flagged, carried forward into the fix-pass as
either fixture-shape gaps (GEM-P-1) or missed code paths
(GEM-P-SF-1).

## 8. Notes

- Codex-family v1.3.0 verdict file was not present on disk at review
  time. The instructions directed independent operation in that case,
  followed. If Codex lands a verdict after this Peer file, the
  cross-family consolidator reconciles per normal.
- Adversarial-same-provider note does not apply here — Gemini family is
  provider-distinct from Claude (author). Peer lens findings carry
  non-advisory weight.
- No P5 downgrades applied: every Peer finding above carries
  direct-run or static-inspection evidence with file:line citations.
  GEM-P-1 was reproduced against both the bundled fixture AND a
  synthesized real rebase scenario (shown in Reproduction column).
- Evidence cap for Gemini family: I operated at `direct-run` ceiling
  per dispatch authorization; framework-default cap (static-inspection
  for families with shell/git/test_runner: false) does not apply
  because full tool access was granted for this session.
