+# CLI Quality Gate
+
+The quality gate protects machine-facing CLI contracts:
+
+- command and flag naming
+- Skills command references
+- executable examples under `--dry-run`
+- default-output facts for semantic review
+- command boundary error contracts
+
+Actions:
+
+- `REJECT` fails CI.
+- `LABEL` asks for taxonomy or compatibility review.
+- `WARNING` is reviewer signal only.
+
+Local run:
+
+```bash
+make quality-gate
+```
+
+`make quality-gate` first exports two local command snapshots:
+
+- `command-manifest.json` covers hand-authored commands used by naming and default-output rules.
+- `command-index.json` covers the full command surface, including generated service commands used by reference and dry-run validation.
+
+CI uploads only `facts.json`; command snapshots are local inputs and are not published as workflow artifacts.
+
+## Legacy Naming Allowlists
+
+`internal/qualitygate/config/allowlists/legacy-commands.txt` and `internal/qualitygate/config/allowlists/legacy-flags.txt` are compatibility records for historical hand-authored public command and flag names that cannot be renamed immediately.
+
+Each non-comment row must include owner, reason, and `added_at`:
+
+```text
+# command	owner	reason	added_at
+drive +task_result	cli-owner	legacy public shortcut	2026-06-05
+
+# command	flag	owner	reason	added_at
+docs +whiteboard-update	input_format	cli-owner	legacy public flag	2026-06-05
+```
+
+Adding a new row requires approval from the matching CODEOWNERS or quality gate owner.
+
+`legacy-commands.txt` only covers hand-authored legacy commands. Generated OpenAPI service commands are intentionally excluded from `command-manifest.json`; they are included in `command-index.json` only so command references can be checked against the real CLI surface.
+
+## Semantic Blocker Policy
+
+The semantic reviewer can propose findings, but the local gatekeeper recomputes whether each finding is reproducible from `facts.json`. A finding blocks only when all of these are true:
+
+- runtime blocking is enabled with repository variable `SEMANTIC_REVIEW_BLOCK=true`;
+- the category is listed in `internal/qualitygate/config/semantic/policy.json`;
+- every evidence item is reproducible from facts;
+- every evidence item matches at least one common rollout group;
+- the finding is not covered by active `internal/qualitygate/config/semantic/waivers.txt` rows that share one `waiver_id`.
+
+The initial blocking rollout is intentionally narrower than the full policy vocabulary. Today, `changed-only` blocks only `error_hint` and `skill_quality`; `default_output` and `naming` remain observe-first until a later rollout explicitly enables them.
+
+| Category | Required evidence | Blocks when enabled by rollout |
+|---|---|---|
+| `error_hint` | `facts.errors[n]` | `required_hint=true` and `hint_action_count=0` |
+| `default_output` | `facts.outputs[n]` | list command lacks a default limit or decision fields |
+| `naming` | `facts.commands[n]` | new hand-authored command or flag conflicts with the naming contract; `legacy_naming=true` never blocks |
+| `skill_quality` | `facts.skills[n]` | invalid command reference |
+
+Evidence that is missing, out of range, the wrong fact kind, or not reproducible is downgraded to a warning.
+
+The `skill_quality` category intentionally uses `facts.skills[n]` evidence. `facts.skill_quality[n]` is currently a document-statistics fact and is not v1 blocker evidence.
+
+### Semantic Rollout Config
+
+Long-lived policy is in JSON:
+
+- `internal/qualitygate/config/semantic/policy.json` controls blockable categories and rollout groups.
+- `internal/qualitygate/config/semantic/models.json` controls allowed model ids and allowed model API base URLs. It does not define a default model; semantic review is skipped unless both `ARK_API_KEY` and `ARK_MODEL` are configured.
+
+Temporary compatibility waivers are in TSV:
+
+```text
+# waiver_id	category	fact_kind	source_file	line	command_path	owner	reason	added_at	expires_at
+wiki-move-202606	skill_quality	skill	skills/lark-wiki/SKILL.md	30		wiki-owner	migration	2026-06-08	2026-07-15
+```
+
+`skill` and `error` waivers must target `source_file + line`. `command` and `output` waivers must target `command_path`. Multi-evidence findings require one waiver row per evidence item, and those rows must share the same `waiver_id`. Expired semantic waivers warn and no longer waive blockers.
+
+## Command Error Contract Rollout
+
+The blocking rule covers command boundary returns only:
+
+- Cobra `RunE` / `Run` function literals.
+- Functions directly referenced by `RunE` / `Run`.
+- Shortcut `Validate` / `Execute` function literals.
+- Functions directly referenced by shortcut `Validate` / `Execute`.
+
+Helper/internal errors are collected as facts or warnings. They are not blocking unless the analyzer proves they are returned directly from a command boundary. Semantic scope fields such as `command_path` and `domain` are filled only when the analyzer can attribute the boundary to a concrete command.
+
+Existing boundary bare errors live in `internal/qualitygate/config/allowlists/legacy-command-errors.txt` with owner, reason, and added_at. New boundary bare errors are rejected.
+
+Useful commands:
+
+```bash
+go run -C lint . --changed-from origin/main ..
+go run -C lint . --print-legacy-command-error-candidates ..
+```
+
+## Branch Protection
+
+The intended required checks are:
+
+- `results` for deterministic gates and existing CI.
+- `semantic-review/result` custom check-run only after the semantic workflow is approved for required-check usage.
+
+The semantic workflow starts in comment-only mode and publishes `semantic-review/observe`. Do not make `semantic-review/observe` required: GitHub treats `neutral` and `skipped` conclusions as successful required-check states.
+
+Blocking mode publishes `semantic-review/result`. Do not add the `semantic-review` workflow job name as a required check.
+
+Before `semantic-review/result` becomes required, facts must be regenerated or independently verified by trusted base code, and no other PR-executable workflow may be able to forge the same check name with `checks: write`.
+
+## CI Rollout Test Plan
+
+Use a temporary sandbox repository created from a fork or private test copy. Do not test required checks directly on the production default branch.
+
+| Scenario | Expected result |
+|---|---|
+| normal branch PR | `results` runs quality gate and uploads `quality-gate-facts-<base_sha>-<head_sha>` |
+| fork PR | deterministic gate runs without secrets; semantic workflow uses trusted `workflow_run` only |
+| stale PR head after CI | semantic verifier rejects mismatched PR head SHA |
+| missing artifact | comment-only publishes `semantic-review/observe=neutral`; blocking publishes `semantic-review/result=failure` |
+| multiple artifacts | verifier rejects the run |
+| tampered zip path traversal | verifier rejects before reading facts |
+| symlink facts entry | verifier rejects before reading facts |
+| missing `ARK_API_KEY` or `ARK_MODEL` | comment-only publishes `semantic-review/observe=neutral`; blocking publishes `semantic-review/result=failure` |
+| model timeout | `internal/qualitygate/cmd/semantic-review` writes a degraded decision; comment-only publishes `semantic-review/observe=neutral`; blocking publishes `semantic-review/result=failure` |
+| blocker fixture with `SEMANTIC_REVIEW_BLOCK=true` | custom check `semantic-review/result` is `failure` on PR head SHA |
+| comment-only mode | custom check `semantic-review/observe` is `success` or `neutral`; observe-only findings do not publish a PR comment by default |
+
+Rollout sequence:
+
+1. Run deterministic `results` as required and semantic review in comment-only mode for one week.
+2. Track false positives by category, rollout group, and owner.
+3. Enable `SEMANTIC_REVIEW_BLOCK=true` only for `changed-only` rollout first.
+4. Enable required custom check `semantic-review/result` only after trusted facts, check-name forgery review, merge-queue compatibility, named owners, and false-positive targets are satisfied.
+5. Roll back by clearing `SEMANTIC_REVIEW_BLOCK`, removing rollout groups or waivers as needed, and removing `semantic-review/result` from required checks; do not remove `results`.
