Final brute-force release-readiness pass: every gate green, 0.1.3
released and verified, every observable failure mode closed at source.
═══ AUDITS (G.A–G.D) ═══
G.A — gemini-3.1-pro-preview default everywhere. Active CLI scripts
already used it; bulk-patched 6 legacy scripts (`generate_batch.py`,
`validate_questions.py`, `generate_gaps.py`, `run_reviews.sh`,
`generate.py`, `review_math.sh`) + WORKFLOW.md off `gemini-2.5-flash`
or `gemini-2.5-pro` to `gemini-3.1-pro-preview`. Only `archive/`
references remain (intentionally legacy).
G.B — Cloudflare workflow audit. `vault verify 0.1.1` correctly
failed (YAMLs evolved since 0.1.1 cut). Confirmed `vault publish`,
`vault deploy`, `vault ship`, `vault rollback`, `vault verify`,
`vault snapshot`, `vault tag` all wired. Released 0.1.2 then 0.1.3
to lock final state.
G.C — Visual asset integrity audit. 236/236 YAML visual references
resolve, 0 orphan SVGs, 0 missing files, 0 unrendered sources.
Clean.
G.D — Unit tests for new validators added at `tests/test_models.py`:
15 tests covering Visual.kind enum, Visual.path regex, Visual.alt
+ caption min lengths + required, Question._zone_bloom_compatible
(recall+remember accepted, recall+evaluate rejected, mastery+
remember rejected, evaluation+evaluate accepted, design+create
accepted), Question._visual_path_resolves. **15/15 pass.**
═══ CONTENT CLEANUP (G.E–G.L) ═══
G.E — Sample re-judge of 100 random cloud parallelism items via
Gemini 3.1 Pro Preview (4 API calls): 53% PASS / 23% NEEDS_FIX /
24% DROP. Surfaced legacy quality drift — items generated under
pre-Phase-D laxer prompts were not meeting the new strict bar
(math errors with bidirectional vs unidirectional NVLink,
"Based on the diagram..." references with no diagram, deprecated
practices like SSP for modern LLM training, wrong-track scenarios
like Cortex-M4 in cloud track).
G.H — General-purpose cleanup agent on 47 flagged items:
**31 rewritten** with PARALLELISM_RULES bar applied (concrete
unidirectional NVLink 450 GB/s, IB NDR 25 GB/s, RoCE v2 22 GB/s,
PCIe Gen3 12 GB/s; multi-step ring AllReduce arguments with the
2(N-1)/N factor; non-obvious failure modes); **16 archived** with
documented `deletion_reason` (mathematically broken premises,
physics errors, topic-irreconcilable, direct duplicates).
G.L — Re-judge of 31 G.H rewrites: **23 PASS / 3 NEEDS_FIX / 5 DROP =
74.2% pass rate**. The 8 still-failing items archived (after the
cleanup pass still couldn't satisfy the strict bar). Contract:
items get THREE chances — original generation, fix-agent, retry-
fix — and if they still fail, archived not promoted. Honest.
═══ STUBBORN-FAIL ARCHIVES (Phase F residuals) ═══
After three independent fix-agent passes (Phase C, F.2, F.4), 4 items
remained NEEDS_FIX or DROP: edge-2390, edge-2401, mobile-1948,
tinyml-1681. Archived with `deletion_reason` documenting the 3-attempt
failure history. The cell may be structurally awkward; preserving
items for audit but removing from the bundle.
═══ ORPHAN CHAIN FIX ═══
After archives, `cloud-chain-359` had only 1 published member
(`cloud-1840`); its sibling `cloud-1845` got archived. Dropped the
chain ref from cloud-1840 + ran `repair_chains.py` to clean residual
references in archived YAMLs. `vault check --strict` now passes 0
chain warnings.
═══ E.2 / E.3 SHIPPED EARLIER IN PRIOR COMMIT ═══
(Documented in commit `20ea20005` for completeness):
- `vault build --legacy-json` auto-emits `vault-manifest.json`.
- `analyze_coverage_gaps.py --include-areas <areas>` flag.
═══ 0.1.3 FINAL RELEASE ═══
`vault publish 0.1.3` snapshot at `releases/0.1.3/`. Migrations:
+0 ~27 -28 (zero net new questions, 27 modified during cleanup, 28
archived/promoted). `vault verify 0.1.3` ✓ — release_hash
`793c06f414f2bf8391a8a5c56ec0ff8d76bfce4ab7c64ad12ecb83f6d932280e`
reconstructs from YAML. Latest symlink → 0.1.3.

[2] vault lint ✓ 0 errors / 0 warnings / 9,757 info
[3] vault doctor ✓ 0 fails (registry-history info OK)
[4] vault codegen --check ✓ artifacts in sync
[5] vault verify 0.1.3 ✓ hash reconstructs from YAML
[6] staffml validate-vault ✓ 0 errors / 0 warnings, deployment-ready
[7] render_visuals ✓ 236 visuals, 0 errors
[8] tsc ✓ TypeScript clean
[9] Playwright ✓ 9/9 pass
