Phase 8: Nyquist Validation Track Verification Report

Phase Goal: Every v1.0 phase has a signed-off Nyquist-compliant validation record with cited evidence, and any blocking gaps are tracked. Verified: 2026-04-13 Status: passed Re-verification: No — initial verification

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
NYQ-01	08-01..08-07 (7 plans)	All 7 v1.0 phases have Nyquist-compliant VALIDATION.md	SATISFIED	7/7 files carry nyquist_compliant: true + ## Nyquist Record; REQUIREMENTS.md line 27 [x]
NYQ-02	08-08	v1.0-VALIDATION-INDEX.md aggregates per-phase status	SATISFIED	File exists at expected path, signed off, 45-row flat table with per-phase anchors; REQUIREMENTS.md line 28 [x]
NYQ-03	08-08	Surfaced gaps tracked as defects or explicitly deferred with rationale	SATISFIED	Gap Validation Block documents all 5 historical-gap-closure rows; Attestation-Gap Residual Risk block explicitly records SCRPT-01..05 attestation weakness deferred to Phase 11 with written rationale and prior sign-off; REQUIREMENTS.md line 29 [x]

Orphaned requirement IDs: none. REQUIREMENTS.md Phase 8 mapping (NYQ-01/02/03) fully accounted for by plan frontmatters (08-01..08-07 → NYQ-01; 08-08 → NYQ-02, NYQ-03).

Anti-Patterns Found

None material. Row-count heterogeneity (14/6/10/5/5/1/4) is legitimate per index line 19 — "a function of scope, single-criterion gap-closure phases legitimately produce single-row audits." No TODO/FIXME/placeholder stubs in the VALIDATION.md outputs.

Known Deviations (user-flagged, verifier judgment)

Deviation 1 — Historical-gap rows recorded as pass rather than fail-fix-v1.1 (08-02 DRV upload-500 + 4 more).

Judgment: Acceptable. Rationale:

• The Phase 8 goal is to produce a signed-off Nyquist record reflecting the current state of the tree, not to retro-actively re-open gaps whose fixes are already shipped and merged.
• All 5 historical-gap-closure rows cite concrete fix commits in fixing phases that have their own signed-off SUMMARY/VERIFICATION artifacts. REQUIREMENTS.md independently confirms UX-01, UX-02, UX-03, PKG-04, RTVAL-01 as Complete.
• The index's Gap Validation Block (lines 80–90) explicitly cross-checks each of the 5 rows against REQUIREMENTS.md + fixing-phase SUMMARY.md with a "Confirmed?" column, then states: "Zero rows inflated to fail-fix-v1.1 because every historical gap is already closed in the tree." This is defensible Nyquist-compliant reasoning, not a cover-up.
• The pattern is consistently applied (5/5 rows, same pattern, explicit rationale), mirrors the 08-01 row 14 precedent the user cited, and satisfies NYQ-03 ("tracked as defects and either fixed in v1.1 or explicitly deferred with rationale") — "fixed in v1.1" is satisfied by "fixed in tree at the time of audit." Marking fail-fix-v1.1 on already-fixed items would be misleading.
• Not a gap.

Deviation 2 — 08-07 UX-03 provenance mismatch (v1.0-ROADMAP says Phase 5-origin, STATE.md restatement says Phase 7 carry-over).

Judgment: Informational only, no action required. The index row (Phase 7 row 4, line 76) explicitly flags this in its Gap Link cell: "Provenance note: v1.0-ROADMAP.md lists UX-03 as Phase 5 deferral, not Phase 7 — STATE.md restatement imprecise; resolution unaffected." The closure citation (Phase 9 plan 09-03 commits d359001 + 68a2935) is correct regardless of origin-phase labeling. Downstream auditors can reconcile. Not a gap.

Additional Observations (informational)

• Roadmap tick lag: .planning/ROADMAP.md line 27 still shows Phase 8 as [ ] while REQUIREMENTS.md already marks NYQ-01/02/03 as [x] Complete and downstream phases 9/10/11 as [x]. This is a ROADMAP bookkeeping lag, not a goal failure. Recommend the orchestrator tick Phase 8 in ROADMAP.md when closing the phase. Does not block passing verification.
• Attestation-gap residual risk (SCRPT-01..05): Documented in index lines 92–94 with explicit ownership by Phase 11 rollout and prior written user sign-off (cd2df1e). Correctly NYQ-03-compliant — explicit deferral with rationale.

Human Verification Required

None. All goal truths are verifiable via file inspection and cross-reference. The phase is a pure audit deliverable; no runtime behavior to exercise.

Gaps Summary

No gaps. The phase has delivered:

1. Seven Nyquist-compliant VALIDATION.md files with frontmatter flags and ## Nyquist Record sections.
2. A signed-off .planning/milestones/v1.0-VALIDATION-INDEX.md with a 45/45 pass tally, per-phase anchors, a Gap Validation Block cross-checking all 5 historical-gap-closure rows, and an explicit Attestation-Gap Residual Risk block for SCRPT-01..05.
3. NYQ-01/02/03 ticked Complete in REQUIREMENTS.md with Phase 8 ownership.

Both user-flagged deviations have been reviewed and judged acceptable — deviation 1 is consistent with NYQ-03's "fixed in v1.1 OR explicitly deferred" wording applied to "already fixed in tree," and deviation 2 is a self-documented informational note with no downstream impact.

Recommendation: Orchestrator can close Phase 8 and tick ROADMAP.md line 27 from [ ] to [x].
