 Tag resolution rules:
-1. **Primary tag selection**: a step may match multiple tags. Pick the primary tag using the **precedence order below** (highest first). The command for the primary tag is what gets emitted; the agent chain is composed from the primary and any secondary tags.
-2. **Precedence order**:
-   1. `build` — when the step is about build/compile/lint/CI failure or build-system work. Beats `fix`: "fix the build error" → `/build-fix`.
-   2. `fix` — when existing behavior is broken/wrong and the domain is not `build`/`test`/`db`/`migration`. Example: "fix the poller crash" → `/orch-fix-defect`. Beats `impl` and `test`: "fix the broken test" → `/orch-fix-defect` (not `/test-coverage`).
-   3. `test` — when the step is about adding or analyzing tests/coverage/e2e, and not fixing a broken test. Beats `impl`: "add tests for the parser" → `/test-coverage`.
-   4. `db` — when the step is about schema/migration/index and not fixing existing behavior. Beats `impl`: "add a users index" → `/orch-add-feature`.
-   5. `migration` — when the step is about porting/upgrading/rewriting and not fixing existing behavior. Beats `impl`: "port the service to Go" → `/orch-change-feature`.
-   6. `change` — when working behavior should change and the domain is not covered above.
-   7. `refactor` — when behavior-preserving restructure and the domain is not covered above.
-   8. `review` — when the step is about reviewing/auditing code or a PR. Beats `security` for general code audits: "audit the code" → `/code-review`.
-   9. `security` — when the step is about hardening a security control (encrypt, auth, secrets, PII). Use this over `review` when the audited object is a security control: "audit the encryption module" → `/security-scan`.
-   10. `impl` — net-new capability; default when the step matches only broad verbs like "implement", "add", "create". Example: "implement OAuth2 login" → `/orch-add-feature`.
-   11. `design`, `plan`, `lookup` — planning/research.
-   12. `docs` — documentation.
-   13. `loop` — autonomous loop.
-3. **Multi-tag notes**: write a one-line command rationale when a secondary tag meaningfully changes risk (for example, an `impl,security` step still emits `/orch-add-feature`; the rationale notes that the composed chain ends with `security-reviewer`).
-4. **Zero-tag steps**: chain is `code-reviewer`; command is `/code-review`; rationale `no tag matched; default review-only chain`.
-5. **Step with an explicit agent name**: if the plan text names an agent (for example, `tdd-guide`), map the step to the command that exercises that agent. For example, a step that says "add tests with tdd-guide" is a `test` step → `/test-coverage`; a step that says "run python-reviewer over auth" is a `review` step → `/code-review` (or `/python-review` if the language is clearly Python). Do not emit raw agent names as commands.

+3. **Special-case overrides** (override the numeric precedence for the stated pairs):
+   - `impl` + `security`: primary is `impl`. The command is `/orch-add-feature`; the chain includes `security-reviewer` as a secondary agent. This prevents net-new feature work from being reduced to a scan.

+5. **Chain length ≤ 4** after deduplication. If exceeded, drop lower-priority agents first: `lookup` and `docs`, then non-reviewer planning/build agents that are not required by the primary tag, then the least-specific reviewer if a more specific reviewer is already present.
+6. **Reviewer-class tail**: after appending, deduplication, and capping, the chain must end with a reviewer-class agent (`<lang>-reviewer`, `code-reviewer`, `security-reviewer`, or `database-reviewer`). The most domain-specific reviewer wins the tail position. If the chain would end with a non-reviewer (e.g., `architect` appended by a `migration` secondary on a `db` primary), move the most domain-specific reviewer to the end. If the chain is now too long, drop the lowest-priority non-reviewer first, but always keep a reviewer tail.
 7. **Zero-tag steps**: chain is `code-reviewer`; command is `/code-review`.
