validate

Post-implementation requirement validation. Verify the built work against scope docs and tasks.json slices, dispatch parallel validators per area, and produce one actionable gap-remediation document. Validation only — never fix.

Core principle (load-bearing)

Definition ≠ Connection ≠ Reachability. A requirement is only delivered if all three hold:

1. Defined — code exists in a file.
2. Connected — it is imported/called by other code.
3. Reachable — a user action can trigger the code path.

Level 1 without 2/3 is dead code that happens to match the description — not complete. Always trace past "X exists" → "X is called by Z at file:line" → "Z fires when the user does W."

Inputs

• $ARGUMENTS — explicit feature name/root or descendant artifact, scope docs, an explicit arbitrary plan as a requirement source, and/or tasks.json to validate against (paths, or "use thread context"), plus optional execution_state.md focus evidence, an immutable BASE_SHA/HEAD_SHA/DIFF_SHA256 candidate tuple, and --orchestrated when a parent workflow owns remediation and the next step. Requirement context is REQUIRED. If absent, ask for a scope or plan path, the task detail JSON path, or "use thread context" — then wait.
• Treat the plan as authoritative when passed. Otherwise use task acceptance slices, scope docs, then usable thread context. Read the authoritative source in full. For tasks.json, extract validation slices from phases[] (parent title/description plus child acceptance criteria/context); do not use execute.md as the validation source except to locate the JSON path.

Working Set (late-bound — read at run-time, never inline)

• Reuse a managed FEATURE_ROOT only when explicit/current-thread evidence ties it to this work (physical directory wins; never branch/recency/lifecycle/scans); distinct work ignores ambient roots. Otherwise, including on collision, standalone MUST first load and follow Skill(spectre-feature-root) through DONE; orchestrated calls escalate. Keep writes beneath it and pass it unchanged.
• Repair stale feature/root metadata in artifacts this workflow touches.
• VALIDATION_REPORT = {FEATURE_ROOT}/validation/validation_gaps.md; create its parent directory.
• Read the actual code, diff, and explicitly supplied requirement artifacts just-in-time.

Method / guardrails

• Chunk into 3–8 validation areas: one per parent task in tasks.json; derive areas from plan outcomes/workstreams when tasks are absent; else use one per "In Scope" item in scope.md, then one per discussed feature. Merge small, split large.
• Execution state is derivative: execution_state.md is evidence/focus only for cross-wave wiring, scope-creep, and dead-computation checks; it is never requirements or acceptance authority.
• Dispatch one @spectre_analyst per area, ALL in parallel in a single message. Brief each with: the area, its source requirement (exact text), expected deliverables, branch, and the status enum + evidence + reachability rules below. Subagents return compressed findings in-thread — no per-area files.
• Status enum (each requirement): ✅ Delivered (defined AND connected AND reachable) · ⚠️ Partial (exists, broken/missing connection) · 🔌 Dead Code (exists, zero usage sites) · ❌ Missing (does not exist).
• Evidence rule (YOU MUST): every requirement cites both a definition site (file:line) and a usage site (file:line). Definition only, no usage → status is ⚠️ or 🔌, never ✅.
• Delivered evidence stays strict: every Delivered result still needs definition plus usage/reachability evidence.
• Reachability + render-backward trace: for UI features, trace from the final render backward — JSX ← variable ← source (hook/prop/computed) ← user action. A broken link anywhere = ⚠️. Grep for usage not just definition (fnName(, <Component, useHook(, prop={).
• Dead-computation + old-path audit: flag any computed value that never reaches a render (🔌), and any old code path still active after new code replaced it (⚠️, new path bypassed / duplicate data source).
• Note scope creep — anything built beyond the requirements.
• Final wiring check before any ✅: consumer connected? render chain unbroken? old path removed? no orphaned computation? single data source? Any failure downgrades ✅ → ⚠️ and adds a gap task.
• No fixes. Report and hand back.
• Candidate pin. When any candidate field is supplied, require all three; recompute the canonical hash using git diff --binary --full-index --no-ext-diff --no-color --no-renames before dispatch and after report creation. Record the unchanged tuple in the report; otherwise return a stale-candidate result.

Outputs + DONE

Write VALIDATION_REPORT. Required sections:

VALIDATION_REPORT begins with its title followed immediately by the Feature/Feature Root metadata below.

0. Self-location metadata — immediately below the title: Feature: <feature-name> and Feature Root: .spectre/features/<feature-name>.
1. Summary — overall status (Complete | Needs Work | Significant Gaps) · {X of Y} delivered · gap count · scope-creep count · supplied candidate tuple.
2. Gap Remediation Tasks — phased by priority (Critical / Medium / Low). Each gap: requirement · current state · gap; each action carries Produces / Consumed by / Replaces and verifiable check-box outcomes.
3. Scope Creep Review — items beyond scope (Keep+document / Remove / Discuss) with evidence.
4. Validation Coverage table — Area · Status · Definition · Usage · Render Chain.
5. Dead Computations Found table — Variable · File · Computed By · Should Be Consumed By.
6. Old Code Paths Still Active table — Old Path · Location · Replaced By · Impact.

DONE when: validation_gaps.md exists with all six numbered sections plus self-location metadata; every area has a status from the enum with definition+usage evidence; any supplied candidate tuple is recorded and unchanged; gaps are actionable (Produces/Consumed-by/Replaces); scope creep noted; no code was modified.

Handoff

Return a short summary: status, {X of Y} delivered, gap count, scope-creep count, 1–2 sentence key findings, and the report path.

• --orchestrated → return the summary and gap categories to the caller without user-facing Next Steps.
• Standalone Needs Work / Significant Gaps → Next (recommended): spectre-fix — validation found {gap signal}; rerun spectre-validate afterward. Route boundary/requirement ambiguity to spectre-scope; route user-flow/state/copy ambiguity to spectre-ux.
• Standalone Complete → Next (recommended): spectre-prove — wiring is delivered, but the public user workflow still needs acceptance evidence. Use test/clean only when proof is explicitly unnecessary or deferred.

Offer spectre-handoff only when pausing on a standalone validation boundary.

Escalate-If

• No scope/tasks docs and no usable thread context → ask before dispatching.
• A gap implies a scope/requirements change rather than a wiring defect → surface to the user; do not silently re-scope.
