# Phase 8 Plan 08: v1.0 Validation Index Rollup & Sign-Off Summary
Aggregated all 7 per-phase Nyquist Records into a single flat 45-row rollup index, obtained human sign-off from Sébastien QUEROL, replicated the sign-off into every per-phase VALIDATION.md, and closed NYQ-01/02/03 in REQUIREMENTS.md — formally closing Phase 8 and the v1.1 Nyquist Validation Track.
## What Was Built
- **`.planning/milestones/v1.0-VALIDATION-INDEX.md`** — single flat pass/fail rollup with one row per v1.0 success criterion (45 rows: 14 + 6 + 10 + 5 + 5 + 1 + 4 across Phases 17). Each row cites evidence as a markdown link into the per-phase `NN-VALIDATION.md#nyquist-record`. Gap Validation Block confirms every fixing-phase citation against REQUIREMENTS.md and SUMMARY.md files. Attestation-Gap Residual Risk block captures the Phase 4 runtime-half weakness as a known rollout concern rather than a fail-fix row.
- **7 per-phase VALIDATION.md sign-off blocks** — all now carry `- [x] Nyquist audit complete — 2026-04-13 — Sébastien QUEROL` mirroring the index, and `**Approval:**` line upgraded from `pending` (phases 15) / audit-only (phases 67) to full human-signed-off text with back-link to the index.
- **REQUIREMENTS.md** — NYQ-02 and NYQ-03 flipped `[ ] → [x]`, Traceability table rows Pending → Complete. NYQ-01 was already Complete from plans 08-01..08-07.
## Tasks Completed
| Task | Description | Commit |
| ---- | --------------------------------------------------------------------------- | ------ |
| 1 | Compile `v1.0-VALIDATION-INDEX.md` rollup (45/45 pass, draft, tally block) | 192a64d |
| 2 | Human sign-off checkpoint | — (approval: Sébastien QUEROL 2026-04-13) |
| 3 | Flip index to signed-off, tick 7 per-phase sign-offs, tick NYQ-02/03 | (this commit) |
## Key Decisions
1. **Zero fail-fix-v1.1 rows.** Every historical gap across the 7-phase track was already closed in place via fixing phases (Phase 6 icon embedding, Phase 9 UX-01/02/03, Phase 10 RTVAL-01). Gap Validation Block in the index cross-checks all 5 historical-gap rows against REQUIREMENTS.md and fixing-phase SUMMARY.md files — all confirmed.
2. **Phase 4 attestation-only runtime half is NOT reopened.** RTVAL-02/03/04 attestation-only PASSes (per STATE.md 2026-04-13 and plan 10-03 sign-off commit cd2df1e) are recorded in the Attestation-Gap Residual Risk block as a known weakness owned by Phase 11 rollout for artifact re-capture. Reopening as fail-fix would contradict the already-shipped plan 10-03 sign-off.
3. **Bidirectional closure loop** between `05-VALIDATION row 4` and `06-VALIDATION row 1` (PKG-04 icon embedding) preserved and flagged as a replicable pattern for future gap-closure phases.
4. **Sign-off replicated, not centralized.** Each per-phase VALIDATION.md carries its own dated sign-off line back-linking to `v1.0-VALIDATION-INDEX.md` — greppable from either direction.
## Deviations from Plan
None — plan executed exactly as written. Frontmatter `nyquist_compliant: true` was already set in all 7 phase files by prior plans 08-01..08-07; Task 3 step 2 consistency-check confirmed this and only the sign-off line + Approval text required edits. Phases 5 and 6 had already ticked the `nyquist_compliant:` checkbox in the Validation Sign-Off block; Phases 14 and 7 had not — all now ticked.
## Success Criteria — Final State
1. **NYQ-01 satisfied** — all 7 v1.0 phases have Nyquist-compliant VALIDATION.md (already ticked; confirmed here)
2. **NYQ-02 satisfied** — single flat pass/fail rollup at `.planning/milestones/v1.0-VALIDATION-INDEX.md`, signed off
3. **NYQ-03 satisfied** — every gap linked to a fixing phase (5 historical-gap rows, all verified) or explicitly deferred with rationale (Phase 4 attestation-only rows in Residual Risk block)
4. **Human sign-off recorded** in both the index frontmatter + sign-off line and each of the 7 per-phase VALIDATION.md Approval blocks
Phase 8 is now formally closed. v1.1 Nyquist Validation Track complete. All remaining v1.1 phases (9, 10, 11) were already closed prior to this plan per STATE.md.
## Self-Check: PASSED
- File `.planning/milestones/v1.0-VALIDATION-INDEX.md` exists and frontmatter shows `status: signed-off`
- Sign-off line ticked: `- [x] Nyquist audit complete — 2026-04-13 — Sébastien QUEROL`
- All 7 per-phase VALIDATION.md files carry matching dated sign-off lines
- REQUIREMENTS.md NYQ-01/02/03 all `[x]`, Traceability rows all Complete
- Prior commit `192a64d` verified present in git log
