openhands 149211c78d chore: gardener housekeeping 2026-03-23
- dev/AGENTS.md: document two-tier priority queue (priority+backlog first,
  then plain backlog); note do_merge() HTTP 405 already-merged detection
- gardener/AGENTS.md: document merge-through protocol (stay alive through
  CI/review/merge); note session kill on PHASE:escalate
- lib/AGENTS.md: add ensure_priority_label() to ci-helpers.sh entry;
  document optional CALLBACK param in run_formula_and_monitor()
- predictor/AGENTS.md: update watermark (content already current from v2 PR)
- Update watermarks for action, planner, review, supervisor, vault, root

Grooming actions:
- #574: added ## Affected files section (lib/parse-deps.sh) to meet quality gate
- #568: escalated — needs human decision on guard/merge architecture
- #466: escalated — dep #393 closed; needs decision on external vs in-repo example

# Gardener Agent
**Role**: Backlog grooming — detect duplicate issues, missing acceptance
criteria, oversized issues, stale issues, and circular dependencies. Enforces
the quality gate: strips the `backlog` label from issues that lack acceptance
criteria checkboxes (`- [ ]`) or an `## Affected files` section. Invokes
Claude to fix or escalate to a human via Matrix.
**Trigger**: `gardener-run.sh` runs 4x/day via cron. It creates a tmux
session with `claude --model sonnet`, injects `formulas/run-gardener.toml`
with escalation replies as context, monitors the phase file, and cleans up
on completion or timeout (2h max session). No action issues — the gardener
runs directly from cron like the planner, predictor, and supervisor.
**Key files**:
- `gardener/gardener-run.sh` — Cron wrapper + orchestrator: lock, memory guard,
consumes escalation replies, sources disinto project config, creates tmux session,
injects formula prompt, monitors phase file via custom `_gardener_on_phase_change`
callback (passed to `run_formula_and_monitor`). Kills session on `PHASE:escalate`
to prevent zombies. Stays alive through CI/review/merge cycle after `PHASE:awaiting_ci`
— injects CI results and review feedback, re-signals `PHASE:awaiting_ci` after
fixes, signals `PHASE:awaiting_review` on CI pass. Executes pending-actions
manifest after PR merge.
- `formulas/run-gardener.toml` — Execution spec: preflight, grooming, dust-bundling, blocked-review, agents-update, commit-and-pr
- `gardener/pending-actions.json` — Manifest of deferred repo actions (label changes,
closures, comments, issue creation). Written during grooming steps, committed to the
PR, reviewed alongside AGENTS.md changes, executed by gardener-run.sh after merge.
**Environment variables consumed**:
- `CODEBERG_TOKEN`, `CODEBERG_REPO`, `CODEBERG_API`, `PROJECT_NAME`, `PROJECT_REPO_ROOT`
- `PRIMARY_BRANCH`, `CLAUDE_MODEL` (set to sonnet by gardener-run.sh)
- `MATRIX_TOKEN`, `MATRIX_ROOM_ID`, `MATRIX_HOMESERVER`
**Lifecycle**: gardener-run.sh (cron 0,6,12,18) → lock + memory guard →
consume escalation replies → load formula + context → create tmux session →
Claude grooms backlog (writes proposed actions to manifest), bundles dust,
reviews blocked issues, updates AGENTS.md, commits manifest + docs to PR →
`PHASE:awaiting_ci` (stays alive) → CI pass → `PHASE:awaiting_review`
review feedback → address + re-signal → merge → gardener-run.sh executes
manifest actions via API → `PHASE:done`. On `PHASE:escalate`: session killed
immediately.
