# Implementation Report: Spec 416 - TenantPilot Agent Skill Layer V1 and Router Integration

## A. Branch / HEAD / Dirty State

- Branch: `416-tenantpilot-agent-skill-layer-v1`
- HEAD: `ca0f5461 feat: add generic content-backed coverage capture (#482)`
- Preflight dirty state: untracked corrected spec package and untracked `.codex/skills/tenantpilot-*` artifacts were already present before implementation.
- Final dirty state: `Agents.md` modified; `.agent/skills/**` created; active Spec 416 package remains untracked. The excluded `.codex/skills/README.md` and `.codex/skills/tenantpilot-*` artifacts are no longer present in the working tree.

## B. Files Created

- `.agent/skills/README.md`
- `.agent/skills/repo-contracts/workspace-scope-safety/SKILL.md`

## D. Skills Created

- `repo-contracts/workspace-scope-safety`
- `repo-contracts/rbac-action-safety`
- `repo-contracts/operation-run-truth`

## E. AGENTS.md Router Added: yes/no

Yes. The tracked repository path is `Agents.md`; the section title is `TenantPilot Agent Skill Router`.

## F. Maturity / Gate Type Summary

- L4 hard gates: workspace scope safety, RBAC/action safety, OperationRun truth, customer output gate, evidence anchor contract, provider freshness semantics.
- L3 checklist gates: spec readiness gate, product surface gate, Filament/Livewire v5 change loop.
- L2/L3 workflow: browser read-only audit.
- L3 temporary migration gate: TCM cutover guard.

## G. Quarantine Rules Included

Included in `.agent/skills/README.md` and relevant `SKILL.md` files:

- `tenant_id` as platform-core ownership truth
- Coverage v1 vocabulary as customer truth
- v1-v2 adapters
- fallback readers
- dual writes
- fallback-to-latest evidence
- OperationRun as default customer proof
- stale provider Healthy/Ready semantics
- limited customer download vocabulary
- raw provider/evidence payload default display
- Product Surface runtime framework
- historical audits as current truth

## H. Verification Commands Run

- `find .agent/skills -name 'SKILL.md' -print | sort` - passed; 11 required skill files listed.
- `grep -n "TenantPilot Agent Skill Router" AGENTS.md` - passed at line 404.
- `grep -n ".agent/skills/README.md" AGENTS.md` - passed at line 406.
- `grep -n "Do not load all skills by default" AGENTS.md` - passed at line 407.
- `grep -n "Hard-gate skills are blocking" AGENTS.md` - passed at line 409.
- `grep -n "Inventory-only specs are hints" AGENTS.md` - passed at line 411.
- Required `SKILL.md` heading validation - passed for all generated skills.
- Generic standards-only path check for `soc2`, `gdpr`, `ssdf`, and `enterprise-best-practice` - passed; none found.
- TCM expiry/review language check - passed.
- Forbidden runtime/test/config/package path check - passed.
- Excluded `.codex/skills/**` target check - passed; no corrected Spec 416 `.codex/skills/README.md` or `.codex/skills/tenantpilot-*` artifacts remain in `git status` or `git diff`.
- `git diff --check -- Agents.md specs/416-tenantpilot-agent-skill-layer-v1` - passed for tracked modifications.
- `.agent/skills/**` trailing-whitespace check - passed for untracked new files.
- `specs/416-tenantpilot-agent-skill-layer-v1/**` trailing-whitespace check - passed for untracked active spec files.
- `git status --short --untracked-files=all` - recorded; includes only allowed implementation paths: `Agents.md`, `.agent/skills/**`, and `specs/416-tenantpilot-agent-skill-layer-v1/**`.

## I. Runtime Files Changed: yes/no

No.

- Runtime UI files changed: no.
- UI impact / no-impact decision: `N/A - no rendered UI surface changed`.
- Product Surface exceptions: none.
- Browser proof: `N/A - no rendered UI surface changed`.
- Human Product Sanity result: N/A for rendered product UI; workflow sanity is limited to router clarity, no load-all behavior, and no false authority over current repo truth.
- Visible complexity outcome: neutral for rendered product UI; agent workflow selection is explicit and bounded.
- No-legacy confirmation: corrected skill library is `.agent/skills/**`; `.codex/skills/**` is not a Spec 416 target.
- Completed-spec rewrite assertion: no completed historical specs were rewritten, normalized, reopened, or stripped of validation/task/browser/review history.
- Livewire v4 compliance: no Livewire code changed; app baseline remains Livewire v4.
- Provider registration location: no panel provider change; Laravel panel providers remain in `apps/platform/bootstrap/providers.php`.
- Global search posture: no Filament resources changed.
- Destructive/high-impact action posture: no application actions changed.
- Asset strategy: no assets registered; `filament:assets` is not required by this spec.
- Deployment impact: none for env vars, migrations, queues, scheduler, storage, runtime assets, or Dokploy deployment.

## J. Tests Changed: yes/no

No.

## K. Migrations Changed: yes/no

No.

## L. Config Changed: yes/no

No.

## M. PASS / PASS WITH CONDITIONS / FAIL

PASS

No unresolved merge-readiness conditions remain for the corrected Spec 416 scope. The final working tree contains only allowed implementation paths: `.agent/skills/**`, `Agents.md`, and `specs/416-tenantpilot-agent-skill-layer-v1/**`.
