| `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`. `ci_commit_status <sha>` — queries Woodpecker directly for CI state, falls back to forge commit status API. `ci_pipeline_number <sha>` — returns the Woodpecker pipeline number for a commit, falls back to parsing forge status `target_url`. | dev-poll, review-poll, review-pr, supervisor-poll |
| `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` / `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/guard.sh` | `check_active(agent_name)` — reads `$FACTORY_ROOT/state/.{agent_name}-active`; exits 0 (skip) if the file is absent. Factory is off by default — state files must be created to enable each agent. **Logs a message to stderr** when skipping (`[check_active] SKIP: state file not found`), so agent dropout is visible in cron logs. Sourced by dev-poll.sh, review-poll.sh, action-poll.sh, predictor-run.sh, supervisor-run.sh. | cron entry points |
| `lib/mirrors.sh` | `mirror_push()` — pushes `$PRIMARY_BRANCH` + tags to all configured mirror remotes (fire-and-forget background pushes). Reads `MIRROR_NAMES` and `MIRROR_*` vars exported by `load-project.sh` from the `[mirrors]` TOML section. Failures are logged but never block the pipeline. Sourced by dev-poll.sh and dev/phase-handler.sh — called after every successful merge. | dev-poll.sh, phase-handler.sh |
| `lib/build-graph.py` | Python tool: parses VISION.md, prerequisite-tree.md, AGENTS.md, formulas/*.toml, evidence/, and forge issues/labels into a NetworkX DiGraph. Runs structural analyses (orphaned objectives, stale prerequisites, thin evidence, circular deps) and outputs a JSON report. Used by `review-pr.sh` (per-PR changed-file analysis) and `predictor-run.sh` (full-project analysis) to provide structural context to Claude. | review-pr.sh, predictor-run.sh |
| `lib/tea-helpers.sh` | `tea_file_issue(title, body, labels...)` — create issue via tea CLI with secret scanning; sets `FILED_ISSUE_NUM`. `tea_relabel(issue_num, labels...)` — replace labels using tea's `edit` subcommand (not `label`). `tea_comment(issue_num, body)` — add comment with secret scanning. `tea_close(issue_num)` — close issue. All use `TEA_LOGIN` and `FORGE_REPO` from env.sh. Labels by name (no ID lookup). Tea binary download verified via sha256 checksum. Sourced by env.sh when `tea` binary is available. | env.sh (conditional) |
| `lib/agent-session.sh` | Shared tmux + Claude session helpers: `create_agent_session()`, `inject_formula()`, `agent_wait_for_claude_ready()`, `agent_inject_into_session()`, `agent_kill_session()`, `monitor_phase_loop()`, `read_phase()`, `write_compact_context()`. `create_agent_session(session, workdir, [phase_file])` optionally installs a PostToolUse hook (matcher `Bash\|Write`) that detects phase file writes in real-time — when Claude writes to the phase file, the hook writes a marker so `monitor_phase_loop` reacts on the next poll instead of waiting for mtime changes. Also installs a StopFailure hook (matcher `rate_limit\|server_error\|authentication_failed\|billing_error`) that writes `PHASE:failed` with an `api_error` reason to the phase file and touches the phase-changed marker, so the orchestrator discovers API errors within one poll cycle instead of waiting for idle timeout. Also installs a SessionStart hook (matcher `compact`) that re-injects phase protocol instructions after context compaction — callers write the context file via `write_compact_context(phase_file, content)`, and the hook (`on-compact-reinject.sh`) outputs the file content to stdout so Claude retains critical instructions. When `phase_file` is set, passes it to the idle stop hook (`on-idle-stop.sh`) so the hook can **nudge Claude** (up to 2 times) if Claude returns to the prompt without writing to the phase file — the hook injects a tmux reminder asking Claude to signal PHASE:done or PHASE:awaiting_ci. The PreToolUse guard hook (`on-pretooluse-guard.sh`) receives the session name as a third argument — formula agents (`gardener-*`, `planner-*`, `predictor-*`, `supervisor-*`) are identified this way and allowed to access `FACTORY_ROOT` from worktrees (they need env.sh, AGENTS.md, formulas/, lib/). **OAuth flock**: when `DISINTO_CONTAINER=1`, Claude CLI is wrapped in `flock -w 300 ~/.claude/session.lock` to queue concurrent token refresh attempts and prevent rotation races across agents sharing the same credentials. `monitor_phase_loop` sets `_MONITOR_LOOP_EXIT` to one of: `done`, `idle_timeout`, `idle_prompt` (Claude returned to `>` for 3 consecutive polls without writing any phase — callback invoked with `PHASE:failed`, session already dead), `crashed`, or `PHASE:escalate` / other `PHASE:*` string. **Unified escalation**: `PHASE:escalate` is the signal that a session needs human input (renamed from `PHASE:needs_human`). **Callers must handle `idle_prompt`** in both their callback and their post-loop exit handler — see [`docs/PHASE-PROTOCOL.md` idle_prompt](docs/PHASE-PROTOCOL.md#idle_prompt-exit-reason) for the full contract. | dev-agent.sh, action-agent.sh |
