chore: gardener housekeeping 2026-03-23

- Update AGENTS.md watermarks to current HEAD (9ec0c02)
- lib/AGENTS.md: document parse-deps.sh inline scan now skips fenced
  code blocks to prevent false positives from code examples in issue bodies
- No blocked issues to review
- Pending actions: none

 # Shared Helpers (`lib/`)
 
 All agents source `lib/env.sh` as their first action. Additional helpers are

 | `lib/ci-helpers.sh` | `ci_passed()` — returns 0 if CI state is "success" (or no CI configured). `ci_required_for_pr()` — returns 0 if PR has code files (CI required), 1 if non-code only (CI not required). `is_infra_step()` — returns 0 if a single CI step failure matches infra heuristics (clone/git exit 128, any exit 137, log timeout patterns). `classify_pipeline_failure()` — returns "infra \<reason>" if any failed Woodpecker step matches infra heuristics via `is_infra_step()`, else "code". `ensure_priority_label()` — looks up (or creates) the `priority` label and returns its ID; caches in `_PRIORITY_LABEL_ID`. | dev-poll, review-poll, review-pr, supervisor-poll |
 | `lib/ci-debug.sh` | CLI tool for Woodpecker CI: `list`, `status`, `logs`, `failures` subcommands. Not sourced — run directly. | Humans / dev-agent (tool access) |
 | `lib/load-project.sh` | Parses a `projects/*.toml` file into env vars (`PROJECT_NAME`, `CODEBERG_REPO`, `WOODPECKER_REPO_ID`, monitoring toggles, Matrix config, etc.). | env.sh (when `PROJECT_TOML` is set), supervisor-poll (per-project iteration) |
-| `lib/parse-deps.sh` | Extracts dependency issue numbers from an issue body (stdin → stdout, one number per line). Matches `## Dependencies` / `## Depends on` / `## Blocked by` sections and inline `depends on #N` patterns. Not sourced — executed via `bash lib/parse-deps.sh`. | dev-poll, supervisor-poll |

Matches `## Dependencies` / `## Depends on` / `## Blocked by` sections and inline `depends on #N` / `blocked by #N` patterns. Inline scan skips fenced code blocks to prevent false positives from code examples in issue bodies. Not sourced — executed via `bash lib/parse-deps.sh`. | dev-poll, supervisor-poll |
 | `lib/matrix_listener.sh` | Long-poll Matrix sync daemon. Dispatches thread replies to the correct agent via tmux session injection (dev, action, vault, review) or well-known files (`/tmp/{agent}-escalation-reply` for supervisor/gardener). Handles all agent reply routing. Run as systemd service. | Standalone daemon |
 | `lib/formula-session.sh` | `acquire_cron_lock()`, `check_memory()`, `load_formula()`, `build_context_block()`, `consume_escalation_reply()`, `start_formula_session()`, `formula_phase_callback()`, `build_prompt_footer()`, `run_formula_and_monitor(AGENT [TIMEOUT] [CALLBACK])` — shared helpers for formula-driven cron agents (lock, memory guard, formula loading, prompt assembly, tmux session, monitor loop, crash recovery). `formula_phase_callback()` handles `PHASE:escalate` (unified escalation path — kills the session; callers may follow up via Matrix). `run_formula_and_monitor` accepts an optional CALLBACK (default: `formula_phase_callback`) so callers can install custom merge-through or escalation handlers. | planner-run.sh, predictor-run.sh, gardener-run.sh, supervisor-run.sh, dev-agent.sh, action-agent.sh |
 | `lib/secret-scan.sh` | `scan_for_secrets()` — detects potential secrets (API keys, bearer tokens, private keys, URLs with embedded credentials) in text; returns 1 if secrets found. `redact_secrets()` — replaces detected secret patterns with `[REDACTED]`. | file-action-issue.sh, phase-handler.sh |
