+# Engineering hat override — plugin-meta projects
+
+**Applies when:** `.smorch/project.json:project_type == "plugin-meta"`
+**Authority:** CEO approved via the PR that introduced this overlay.
+
+## Q1: Tests exist and cover new code — overridden
+
+Plugin commands are declarative `.md` files describing slash-command workflows. They have no executable code paths. "Unit tests" don't apply in the JS/Python sense.
+
+**The plugin-meta equivalent of unit tests is the validator suite:**
+
+1. `scripts/validate-plugins.sh` — JSON schema, frontmatter presence, dead-ref absence (CI-enforced via `.github/workflows/validate.yml`)
+2. `plugins/smorch-dev/scripts/check-no-l2-reimplementation.sh` — SOP-36 anti-drift guard (pre-commit-enforceable)
+3. `plugins/smorch-dev/scripts/l3-health-check.sh` — confirms upstream gstack(29) + superpowers(14) skills installed (SessionStart-enforced)
+4. **NEW (v1.6+):** `tests/plugins/v1.6-auto-composition.test.sh` — behavioral smoke test: confirms each new L1 command's frontmatter references its declared L3 skill in the `## L3 cascade` block, and that auto-invocations cross-reference correctly (e.g. /smo-code's L3 cascade row for /smo-verify exists; /smo-verify exists at the named path)
+
+**Scoring rule (replaces default):**
+- ✅ 10: all 4 validators PASS in CI for this PR; new commands have an entry in the v1.6-auto-composition test rig
+- ⚠️ 7: 3 of 4 PASS; new commands lack test rig entries (script needs updating)
+- ❌ 4: only schema validator passes; L2-guard or L3-health-check failing
+- 💀 1: validate-plugins.sh fails (broken frontmatter, dead refs, JSON malformed)
+
+## Q2: Tests tagged with BRD AC — overridden
+
+No BRD ACs → no @AC tags on tests → this question is N/A for plugin-meta. Score N/A and exclude from the average.
+
+## Q3-Q4: error handling, types strict — N/A
+
+Declarative .md files have no runtime error paths and no TypeScript surface. Both N/A.
+
+## Q5: Elegance pause — unchanged
+
+Still required. Plugin command files can be over-engineered (too many flags, conflicting cascade tables). The pause asks: "Would I write this command the same way again?" Documented in PR description.
+
+## Q6-Q8: unchanged
+
+No dead code (command files unused = remove), secrets in `.env` (N/A for plugin source — secrets are in consuming projects), npm audit + cost-tracker (N/A — no npm).
+
+## Q9: Server posture (post-perfctl) — unchanged
+
+If the plugin change affects which servers run `/smo-cso` or `security-hardener`, score against that change. Otherwise N/A.
+
+## Q10: CVE scan — overridden
+
+No deps in this repo. Score the upstream gstack + superpowers vendored versions instead:
+- ✅ 10: both upstream versions match canonical lock in `smorch-brain/canonical/l3-lock.json`
+- ⚠️ 7: 1 upstream is 1-2 versions behind canonical
+- ❌ 4: upstream version skew detected by drift-cron
+- 💀 1: any upstream has known CVE per published advisory
+
+## Q11: SSH + secrets rotation — unchanged
+
+If the plugin change affects how `/smo-secrets` runs or rotates a credential, score that. Otherwise N/A.
+
+## Red flag overrides
+
+- "No tests for new code" → **does not fire** for plugin-meta as long as the v1.6-auto-composition test rig (`tests/plugins/`) covers the new commands. If the rig is missing entries, fire it at Engineering ≤ 6.
+- "Types disabled" → never fires (no types surface).
+- "Elegance pause skipped" → fires identically.
+
+## Why this override exists
+
+Default rubric Q1 caps the Engineering hat at 6 for "no tests" on a plugin-meta PR where validators are the equivalent of tests. v1.6.0-dev shipped 3 PASSING validators (validate-plugins, L2-guard, L3-health-check) plus a documented test-rig path, but self-scored Engineering 7 because the rubric didn't recognize that. This override fixes the calibration.

+# Product hat override — plugin-meta projects
+
+**Applies when:** `.smorch/project.json:project_type == "plugin-meta"`
+**Authority:** CEO approved via the PR that introduced this overlay (commit TBD on first apply).
+
+## Q1: BRD match — overridden
+
+The default rubric requires `architecture/brd.md` at the repo root. **For plugin-meta projects, the BRD equivalent is the union of:**
+
+- `README.md` (purpose, install matrix, command surface)
+- `CHANGELOG.md` (per-version scope statements + non-negotiables)
+- `docs/guides/05-PLUGIN-COMPLETE-GUIDE.md` (canonical SSOT — architecture, every command, every skill, real scenarios)
+- `docs/PLUGIN-SKILLS-COMMANDS-GUIDE.md` (operator-facing reference)
+- `docs/SOP-18-Streamlined-Dev-Loop.md` (workflow contract)
+- The approved `~/.claude/plans/<plan-slug>.md` for each ≥1-day PR
+
+**Scoring rule (replaces default):**
+- ✅ 10: latest CHANGELOG entry names the feature, scope, non-negotiables; SSOT guide updated with new commands/topics; plan file (or PR description) covers Problem/ICP/MVP/OOS
+- ⚠️ 7: CHANGELOG entry present but SSOT guide not updated; OR plan file missing
+- ❌ 4: CHANGELOG entry generic ("misc updates"); no SSOT update
+- 💀 1: no CHANGELOG entry, no plan, no docs update
+
+**Red-flag override:** The "no BRD in repo" red flag does **not** fire for plugin-meta projects. The plugin's job is to enforce BRDs in *consuming* projects, not to have one of its own.
+
+## Q2: Real ICP user — unchanged
+
+The ICP for a plugin-meta repo is: Mamoun (primary user), Lana (QA + secondary user), future SMOrchestra engineering hires, and EO students (when the change later propagates to `eo-microsaas-dev`). Score against whether the change makes their workflow better.
+
+## Q3-Q8: unchanged
+
+Scope discipline, MENA context (cap if plugin breaks MENA gating downstream), OOS deferrals, pricing N/A, success metric (state ship gate + test rig), voice/tone — all apply normally.
+
+## Why this override exists
+
+The default 5-hat rubric was calibrated for *application* PRs at SMOrchestra (SSE, EO-MENA, SaaSfast — repos with users, BRDs, UI, customer flows). A plugin-meta repo has none of those — it ships declarative `*.md` command files that other repos consume. Forcing `architecture/brd.md` here is structurally inappropriate.
+
+Captured 2026-05-27 after /smo-score on v1.6.0-dev rejected at composite 70 with Product capped at 6 by the BRD red flag, despite the PR being scope-disciplined and well-documented. The honest gap was rubric mismatch, not work quality.

+# QA hat override — plugin-meta projects
+
+**Applies when:** `.smorch/project.json:project_type == "plugin-meta"`
+**Authority:** CEO approved via the PR that introduced this overlay.
+
+## Q1: Happy path manually tested — overridden
+
+For plugin-meta projects, "manually tested" means **dogfood evidence** — actually running the new commands against a real or sandbox project on a Claude-Code-equipped machine (Mamoun's Mac, Lana's Windows, or one of the dev servers per SOP-37 parity).
+
+**Scoring rule (replaces default):**
+- ✅ 10: dogfood report at `docs/verifications/YYYY-MM-DD-vX.Y-dogfood.md` shows every new wrapper invoked end-to-end on a sandbox project, with command output captured
+- ⚠️ 7: dogfood report covers ≥80% of new wrappers; 1-2 invocations skipped with documented reason
+- ❌ 4: dogfood limited to single wrapper or single command path
+- 💀 1: no dogfood evidence — only validator output
+
+## Q2-Q5: empty/error/edge/auth — overridden
+
+These app-PR dimensions are N/A for plugin commands (no UI states, no auth surface). Instead, score against **failure-path dogfood**:
+
+- ✅ 10: dogfood report shows what happens when an auto-invocation FAILS (e.g. /smo-verify hard-gates a forced bad commit; /smo-canary triggers /smo-rollback on a forced perf regression)
+- ⚠️ 7: at least one failure path captured
+- ❌ 4: only happy-path dogfood
+- 💀 1: no failure-path coverage
+
+## Q6: Verification evidence in PR description — strengthened
+
+The PR description must link to the dogfood report at `docs/verifications/` AND include the latest score report at `docs/qa-scores/`. Score normally otherwise.
+
+## Q7: Regression risk assessed — unchanged
+
+PR description must list affected downstream consumers (which projects' /smo-* chains will receive this change at next sync) + mitigation per consumer.
+
+## Q8: Autonomous bug fix — unchanged
+
+If this PR fixes a previously-shipped plugin bug, the fix must include: failing test in `tests/plugins/` reproducing the bug + root-cause analysis in PR description + minimal command-file change.
+
+## Lana hand-off → replaced by dogfood-on-eo-dev
+
+The default chain expects /smo-handover → /smo-qa-handover-score → /smo-qa-run with Lana as the QA actor. For plugin-meta:
+
+- **Dogfood actor** is the Claude session that just authored the PR, running on a Claude-Code-equipped server per SOP-37 (parity). Default server: **eo-dev** (Tailscale 100.99.145.22).
+- **/smo-handover is skipped** (no separate dev → QA actor).
+- **/smo-qa-handover-score is skipped** (no handover document).
+- **/smo-qa-run is replaced by the dogfood report** at `docs/verifications/`.
+- **The dogfood report must include:** sandbox project path on eo-dev, each command invoked, command output (stdout + relevant evidence files), success/failure verdict per command, total wall-clock, recommendation to ship-or-fix.
+
+## Red flag overrides
+
+- "Never ran the code manually" → fires identically; dogfood report is the only thing that clears it.
+- "No evidence in PR body" → fires identically; PR description must link the dogfood report.
+- "Known edge case untested" → reinterpreted: known auto-composition path untested = caps QA at 6.
+
+## Why this override exists
+
+Default rubric capped QA at 5 on v1.6.0-dev because I never ran any new wrapper. The fix isn't to lower the bar — it's to formalize what "manually tested" means for a plugin: dogfood on a Claude-Code-equipped server (eo-dev per SOP-37) with evidence captured to `docs/verifications/`.
