## Summary
- Problem: `src/secrets/target-registry.test.ts` fails on latest `main` because the runtime registry includes Feishu `encryptKey` paths that the docs matrix and surface reference omit.
- Why it matters: the docs/runtime sync guard currently blocks prep and merge work for unrelated PRs, including `#25558`.
- What changed: regenerated the secretref credential matrix and updated the surface reference to include both Feishu `encryptKey` paths.
- What did NOT change (scope boundary): no runtime registry behavior, config semantics, or channel handling changed.

## Repro + Verification
### Environment
- OS: macOS
- Runtime/container: Node.js repo checkout
- Model/provider: N/A
- Integration/channel (if any): Feishu docs/runtime registry sync
- Relevant config (redacted): none
### Steps
1. Check out latest `main` before this change.
2. Run `./node_modules/.bin/vitest run --config vitest.unit.config.ts src/secrets/target-registry.test.ts`.
3. Apply this docs-only sync change and rerun the same command.
### Expected
- The target registry stays in sync with the generated docs matrix and the test passes.
### Actual
- Before this change, the test failed because `channels.feishu.encryptKey` and `channels.feishu.accounts.*.encryptKey` were missing from the docs artifacts.
## Evidence
Attach at least one:
- [x] Failing test/log before + passing after
- [ ] Trace/log snippets
- [ ] Screenshot/recording
- [ ] Perf numbers (if relevant)
## Human Verification (required)
What you personally verified (not just CI), and how:
- Verified scenarios: confirmed the failure on plain latest `main`, applied only these docs entries in a clean bootstrapped worktree, and reran `./node_modules/.bin/vitest run --config vitest.unit.config.ts src/secrets/target-registry.test.ts` to green.
- Edge cases checked: verified both top-level Feishu `encryptKey` and account-scoped `encryptKey` paths are present in the matrix and surface reference.
- What you did **not** verify: full repo test suite and CI beyond the targeted regression.
## Review Conversations
- [x] I replied to or resolved every bot review conversation I addressed in this PR.
- [x] I left unresolved only the conversations that still need reviewer or maintainer judgment.
If a bot review conversation is addressed by this PR, resolve that conversation yourself. Do not leave bot review conversation cleanup for maintainers.
## Compatibility / Migration
- Backward compatible? `Yes`
- Config/env changes? `No`
- Migration needed? `No`
- If yes, exact upgrade steps:
## Failure Recovery (if this breaks)
- How to disable/revert this change quickly: revert this commit.
- Files/config to restore: `docs/reference/secretref-user-supplied-credentials-matrix.json` and `docs/reference/secretref-credential-surface.md`
- Known bad symptoms reviewers should watch for: the target-registry docs sync test failing again for missing Feishu `encryptKey` entries.
## Risks and Mitigations
- Risk: the markdown surface reference could drift from the generated matrix again in a later credential-shape change.
- Mitigation: `src/secrets/target-registry.test.ts` continues to guard docs/runtime sync.
