-# Plan: Issue #137 — doc-map input for path-scoped doc injection
-
-## Problem
-
-review-bot currently injects context via `patterns-repo` (external VCS repos) and `conventions-file` (a single file from the reviewed repo). There is no mechanism to inject local repo documentation files scoped to the paths changed in a PR.
-
-First consumer: `grgl/gargoyle#778` wants a "doc adherence" reviewer that checks code against the module's governing design doc, without injecting every doc in the tree.
-
-## Constraints
-
-- Must work with existing `budget.Fit` architecture (docs go into `SystemBase` section, never trimmed — or added as a new section below `Conventions`)
-- Must not fail the review if doc files are missing (warn + skip)
-- Context guard: default 100KB total injected doc content (configurable)
-- YAML parsing must use `github.com/goccy/go-yaml` (the only approved YAML library)
-- No new third-party dependencies (Go standard library + approved packages only)
-- Path security: doc files must be read via VCS API (not local filesystem), so they are always fetched from the PR head ref within the repo workspace — same path used by `conventions-file` loading
-
-Wait — re-reading the issue: the issue says "local repo files". In the CI action context, the action runner has the repo checked out. The design doc says "read each doc file from the local checkout". But review-bot has no local checkout — it runs as a binary and reads files via VCS API. Let me reconcile:
-
-- `conventions-file` uses `vcs.GetFileContent` (fetches from VCS API, default branch)
-- The doc-map docs should also be read via VCS API
-- The doc-map config file itself (`doc-map` input) is a local file in the workspace (like `system-prompt-file`)
-- The doc paths inside the config ARE relative to the repo root, to be fetched via VCS API
-
-**Conclusion:** The `doc-map` YAML file is read from local filesystem (like `system-prompt-file`). The doc files listed inside are fetched from the VCS API.
-
-Actually, re-reading more carefully: "Read each doc file (or all .md files under a directory) from the local checkout". But review-bot doesn't have a local checkout. Since `system-prompt-file` and `conventions-file` are both read locally, I should follow the same approach consistently.
-
-**Final decision:** The `doc-map` config file is local (passed via `--doc-map` flag, read with `os.ReadFile` after workspace validation). The listed doc paths (and directory expansion) are read via VCS `GetFileContent` / `GetAllFilesInPath` — matching the `conventions-file` pattern for consistency, and enabling it to work on any branch (not just the checked-out one).
-
-## Proposed Approach
-
-### New files
-
-1. `review/docmap.go` — `DocMap` type, YAML parsing, glob matching, doc loading logic
-2. `review/docmap_test.go` — unit tests
-
-### Modified files
-
-1. `cmd/review-bot/main.go` — add `--doc-map` flag, wire up in Step 6c
-2. `.gitea/actions/review/action.yml` — add `doc-map` input, pass as `DOC_MAP_FILE` env var
-3. `budget/budget.go` — add `DesignDocs` section (between `SystemBase`/`Conventions` and `Diff`)
-4. `CHANGELOG.md` — update
-
-### DocMap types (review/docmap.go)
-
-```go
-// DocMapping maps a set of path globs to doc files/directories.
-type DocMapping struct {
-    Paths []string `yaml:"paths"` // glob patterns
-    Docs  []string `yaml:"docs"`  // file paths or directories
-}
-
-// DocMapConfig is the top-level YAML structure.
-type DocMapConfig struct {
-    Mappings []DocMapping `yaml:"mappings"`
-}
-
-// DocMapOptions controls doc loading behavior.
-type DocMapOptions struct {
-    MaxBytes int // default 100*1024
-}
-```
-
-### Key functions
-
-```go
-// ParseDocMapConfig parses the YAML config file from a local path.
-func ParseDocMapConfig(path string) (*DocMapConfig, error)
-
-// MatchDocs returns deduplicated doc paths for the given changed files.
-func MatchDocs(cfg *DocMapConfig, changedFiles []string) []string
-
-// LoadMatchingDocs fetches doc content via VCS, respecting size limit.
-// Returns (content, error). Missing files are warned and skipped.
-func LoadMatchingDocs(ctx context.Context, fetcher DocFetcher, owner, repo string, docPaths []string, opts DocMapOptions) (string, error)
-```
-
-### DocFetcher interface
-
-```go
-// DocFetcher fetches files and directory listings from VCS.
-// Subset of vcsClient, defined here to keep review package free of cmd-level deps.
-type DocFetcher interface {
-    GetFileContent(ctx context.Context, owner, repo, filepath string) (string, error)
-    GetAllFilesInPath(ctx context.Context, owner, repo, path string) (map[string]string, error)
-}
-```
-
-### Glob matching
-
-Use `path.Match` from the Go standard library. It matches patterns like `lib/gargoyle/engine/signal_risk/**`. The `**` glob is NOT natively supported by `path.Match`, so we need either:
-
-a) Use `filepath.Match` which also doesn't support `**`
-b) Implement simple `**` support: `**` matches any number of path segments
-
-**Decision:** Implement minimal `**` support: split path on `/`, split pattern on `/`, match each segment with `filepath.Match`. When a pattern segment is `**`, it consumes any number of remaining segments. This covers the primary use case without a new dependency.
-
-### Budget integration
-
-Add `DesignDocs` field to `budget.Sections`. Position: after `Conventions`, before `FileContext` (trimming order: Patterns → Conventions → DesignDocs → FileContext → Diff). Inject under `## Design Documents` heading in system prompt.
-
-### Context size guard
-
-Accumulate doc content bytes. If total would exceed `MaxBytes`, truncate last doc with a notice and stop loading more.
-
-## State/Data Model
-
-```
-DocMapConfig
-  └── []DocMapping
-        ├── Paths []string  (glob patterns against changed file paths)
-        └── Docs  []string  (local doc paths or directories in target repo)
-
-Flow:
-  1. Parse doc-map YAML → DocMapConfig
-  2. GetPullRequestFiles → []string of changed paths
-  3. MatchDocs(cfg, changedPaths) → deduplicated []string doc paths
-  4. For each doc path:
-       - If path ends with "/" or is a "directory" → GetAllFilesInPath, filter .md
-       - Otherwise → GetFileContent
-  5. Accumulate, respect size limit
-  6. Inject into system prompt
-```
-
-## Error Cases
-
-| Situation | Behavior |
-|-----------|----------|
-| `--doc-map` file not found | Fatal error (like `--system-prompt-file`) |
-| `--doc-map` file invalid YAML | Fatal error with descriptive message |
-| Unknown keys in YAML | Log warning, continue |
-| Doc file not found in VCS | Log warning, skip |
-| Doc directory empty | Log debug, skip |
-| Total size exceeds limit | Truncate with notice, log warning |
-| No changed paths match | No docs injected, review runs normally |
-| `paths` list empty in a mapping | Skip that mapping (no match possible) |
-| `docs` list empty in a mapping | Skip that mapping (nothing to inject) |
-
-## Edge Cases
-
-- Empty `mappings` list → no docs injected, no error
-- Same doc matched by multiple mappings → deduplicate by path
-- Directory with no `.md` files → skip silently (log debug)
-- Very large single doc file → counts against limit, may truncate
-- Symlinks/special files in VCS → GetFileContent handles or errors (warn + skip)
-- `doc-map` path outside workspace → fatal error (validateWorkspacePath)
-- Directory path specified as `docs` entry without trailing `/` → check if it's a directory via ListContents or GetAllFilesInPath; if error, try GetFileContent
-
-## Testing Strategy
-
-### Unit tests (review/docmap_test.go)
-
-1. **ParseDocMapConfig** — valid YAML, invalid YAML, unknown keys (warning), empty file
-2. **MatchDocs** — no match, single match, multi-match, deduplication, `**` glob, exact match
-3. **LoadMatchingDocs** — with mock DocFetcher:
-   - file path → content returned
-   - missing file → warned + skipped
-   - directory path → expands .md files
-   - directory with no .md → empty
-   - size guard → truncation with notice
-   - deduplication in combined results
-
-### Integration coverage
-
-The existing `main_test.go` tests cover flag wiring — add a test for `--doc-map` flag parsing and workspace path validation.
-
-## Open Questions
-
-1. **Directory detection**: The issue says "directory paths expand to all .md files". But review-bot has no local filesystem. When a `docs` entry is `docs/domain/contexts/trading/`, we can call `GetAllFilesInPath`. But what if someone writes `docs/domain/contexts/trading` (no trailing slash)? We could try GetFileContent first, and if it fails with a 404 or "is directory" error, fall back to GetAllFilesInPath. OR we could just always call GetAllFilesInPath and if it returns content, use it; if it returns empty, try GetFileContent. 
-   **Decision**: Try GetAllFilesInPath first (always). If it returns ≥1 file, treat as directory. If it returns 0 files AND no error, try GetFileContent. If GetAllFilesInPath returns an error, try GetFileContent.
-
-2. **Budget section placement**: The issue says docs go in "system prompt after system-prompt-file content". That means docs are part of the system prompt. Current budget: SystemBase (includes additionalPrompt) → Patterns → Conventions. I'll add DesignDocs after Conventions (trim after Conventions). Docs are injected into system prompt via `buildResult`.
-   **Decision**: DesignDocs section in budget, trimmed after Conventions, before FileContext.
-
-3. **Configurable size limit**: The issue says "configurable". Add `--doc-map-max-bytes` flag (default 102400). Pass via `DocMapOptions`.
-   **Decision**: Add flag. Default 100KB (102400 bytes).
-
-## Completion Checklist
-
-1. `doc-map` input added to action.yml with correct env var passthrough
-2. `--doc-map` and `--doc-map-max-bytes` flags parsed in main.go
-3. `doc-map` file validated with `validateWorkspacePath` before reading
-4. YAML parsed with `go-yaml`, unknown keys warned not errored
-5. Glob matching handles `**` segments
-6. Changed files list from PR drives intersection (not hardcoded)
-7. Docs deduplicated before fetching
-8. Missing doc files: warn + skip, not fatal
-9. Context size guard truncates with notice, logs warning
-10. `DesignDocs` section added to `budget.Sections` and `buildResult`
-11. Tests cover: match, no-match, dedup, missing file, directory expansion, size guard, YAML parse error
-12. `go test ./...` passes
-13. `go vet ./...` passes
-14. CHANGELOG updated

+# Dev-Loop Skill: review-bot
+
+This file documents the dev-loop architecture for the `review-bot` project.
+It lives in the repo so changes are version-controlled alongside the code.
+
+## Architecture
+
+Dispatch is a **pure shell script** — no model reasoning.
+
+```
+Cron (agentTurn, toolsAllow: [exec, sessions_spawn, read])
+  → runs dispatch script
+  → reads output for SPAWN or HANDOFF lines
+  → spawns worker if instructed
+
+Dispatch script  (~/.openclaw/workspace/scripts/dev-loop-dispatch.sh)
+  → pure bash, all decisions are curl API calls + branches
+  → exits after emitting one SPAWN line (at most one worker per run)
+  → emits HANDOFF for each qualifying PR (does not exit after HANDOFF)
+
+Workers (Opus, spawned by cron model)
+  → receive precise task description
+  → do one job: self-review, fix CI, address feedback, or implement
+  → remove wip label when done, reply NO_REPLY
+```
+
+The cron model's **only** job: run script, read output, spawn worker if told to.
+The model **never** assesses project state or makes dispatch decisions.
+
+## Safety Invariants
+
+1. **NEVER MERGE** — no merge API call exists anywhere in the script or worker templates
+2. **REQUEST_CHANGES always blocks** — checked first, before CI, before self-review, before handoff
+3. **WIP mutex** — one active worker per repo; WIP label gates new issue pickup
+4. **One SPAWN per run** — script emits at most one SPAWN line per execution
+5. **set -euo pipefail** — any curl failure aborts immediately, no partial actions
+6. **Workers reply NO_REPLY** — no dispatch-level side effects (workers may push changes and manage labels as part of their task)
+
+## Dispatch Rules (in order)
+
+| Rule | Condition | Action |
+|------|-----------|--------|
+| 0 | WIP label > 1hr old | Remove stale WIP, continue |
+| 0b | WIP label ≤ 1hr old | Mark ACTIVE_WIP=1, continue (only gates Rule 10) |
+| _(1)_ | _(reserved — intentionally unused)_ | — |
+| 2 | Any reviewer has REQUEST_CHANGES | SPAWN:findings |
+| 3 | PR not mergeable | SPAWN:rebase |
+| 4 | CI failure, no fix plan | SPAWN:ci-fix |
+| 4b | CI failure, fix plan exists | Skip (worker in progress) |
+| 5 | Bot review missing | Wait |
+| 6 | CI pending/unknown | Wait |
+| 7 | No clean self-review, no fix plan | SPAWN:self-review |
+| 7b | Self-review needs attention, no fix plan | SPAWN:sr-fix |
+| 8 | Unacknowledged bot review findings | SPAWN:address-feedback |
+| 9 | Unresolved inline diff comments | SPAWN:address-feedback |
+| 10 | All checks pass | HANDOFF |
+| 11 | No open PRs + no ACTIVE_WIP | SPAWN:impl (next issue) |

+    {{PR_NUM}}, and {{HEAD_SHA}}, then spawn with sessions_spawn(mode: "run",
+    model: "hai-anthropic/anthropic--claude-4.6-opus", thinking: "high").
+
+    If no SPAWN line in output, reply NO_REPLY.
+
+    See ~/.openclaw/workspace/skills/dev-loop/SKILL.md for full instructions.
+    (This repo's SKILL.md is deployed to that workspace path.)

+# Design: doc-map input for path-scoped design doc injection (Issue #137)
+
+## Problem
+
+review-bot can inject context via `patterns-repo` (external VCS repos) and `conventions-file`
+(a single file from the reviewed repo). There is no mechanism to inject local repo documentation
+files scoped to the paths changed in a PR.
+
+First consumer: `grgl/gargoyle#778` needs a "doc adherence" reviewer that checks code against the
+module's governing design doc, without injecting every doc in the tree.
+
+## Approach
+
+### New: `doc-map` input
+
+A `.review-bot/doc-map.yml` config file in the reviewed repo maps source path globs to governing
+design docs. review-bot reads the map, intersects it with changed PR paths, and injects only the
+relevant docs into the system prompt.
+
+### Config format
+
+```yaml
+mappings:
+  - paths:
+      - "lib/gargoyle/engine/signal_risk/**"
+    docs:
+      - docs/domain/contexts/risk/risk-controls.md
+  - paths:
+      - "lib/gargoyle/trading/**"
+    docs:
+      - docs/domain/contexts/trading/
+```
+
+- `paths` — glob patterns (including `**`) matched against changed file paths in the PR
+- `docs` — file paths or directory paths (all `.md` files under a directory) to inject
+- Docs are deduplicated across mappings
+
+### Architecture
+
+| Component | Description |
+|-----------|-------------|
+| `review/docmap.go` | YAML parsing, glob matching with `**` support, doc loading via VCS |
+| `cmd/review-bot/main.go` | Step 6c: parses config, intersects with changed files, calls LoadMatchingDocs |
+| `budget/budget.go` | New `DesignDocs` section — injected after Conventions in system prompt |
+| `action.yml` | `doc-map` and `doc-map-max-bytes` inputs, wired to `DOC_MAP_FILE`/`DOC_MAP_MAX_BYTES` |
+
+### Doc file loading
+
+- The `doc-map` YAML file is read from the local workspace (like `system-prompt-file`).
+- Doc files listed in the config are fetched via VCS API (same as `conventions-file`),
+  enabling them to be loaded from any branch without a local checkout.
+- `GetAllFilesInPath` is tried first; if it returns files, they are treated as a directory listing.
+  If it returns empty, `GetFileContent` is tried as a fallback (single file).
+
+### Glob matching
+
+`**` is implemented by splitting patterns and paths on `/`, then matching segment-by-segment.
+A `**` segment consumes zero or more path segments (not just one level like `*`).
+
+### Budget integration
+
+`DesignDocs` is added to `budget.Sections` between `Conventions` and `FileContext`.
+Trim order: Patterns → Conventions → DesignDocs → FileContext → Diff.
+Design docs appear in the system prompt under `## Design Documents`.
+
+### Context size guard
+
+Default: 100 KB. Configurable via `--doc-map-max-bytes` / `DOC_MAP_MAX_BYTES`.
+Truncation is noted inline with a `⚠️` message.
+
+## Error handling
+
+| Situation | Behavior |
+|-----------|----------|
+| `--doc-map` file not found | Fatal error (like `--system-prompt-file`) |
+| `--doc-map` file invalid YAML | Fatal error with descriptive message |
+| Unknown YAML keys | Log warning, continue |
+| Doc file not found in VCS | Log warning, skip |
+| Doc directory empty or no `.md` files | Log debug, skip |
+| Total size exceeds limit | Truncate with notice, log warning |
+| No changed paths match any mapping | No docs injected, review runs normally |
+| `paths` or `docs` list empty in a mapping | Skip that mapping |

+# Dev-Loop Dispatch Spec
+
+**Version:** 1.0
+**Status:** Implemented
+**Implements:** Issue #148
+
+This document is the authoritative spec for the review-bot dev-loop dispatch architecture.
+The dispatch script (`~/.openclaw/workspace/scripts/dev-loop-dispatch.sh`) and its tests
+are validated against the rules and invariants in this document.
+
+---
+
+## 1. Overview
+
+The dev-loop is a 15-minute cron that advances the state of open pull requests and picks up
+new issues when there is nothing in review. It is designed for **zero human intervention**
+in the normal flow and **hard stops at key safety boundaries**.
+
+### Architecture
+
+```
+Cron (15-min cadence)
+  → exec: bash dev-loop-dispatch.sh <project>
+  → read stdout for SPAWN/HANDOFF lines
+  → if SPAWN: load worker template, spawn subagent
+  → if HANDOFF: log, do nothing else
+  → if neither: NO_REPLY
+```
+
+The cron model has **no ambient knowledge** of the project state. All state is derived
+from the dispatch script's output, which in turn comes from live API calls.
+
+---
+
+## 2. Inputs
+
+### Project Config
+
+```yaml
+# memory/projects/<project>.yaml
+repo: rodin/review-bot         # <owner>/<repo>
+api_base: https://gitea.../v1  # API base URL
+token_path: ~/.openclaw/...    # path to bearer token
+user: rodin                    # bot Gitea username
+labels:
+  wip: <id>
+  ready: <id>
+review_bots:                   # sentinel names in review bodies
+  - sonnet
+  - gpt
+  - security
+```
+
+### Script Arguments
+
+```bash
+bash dev-loop-dispatch.sh <project>   # normal run
+DRY_RUN=1 bash dev-loop-dispatch.sh <project>   # dry-run (no mutations)
+```
+
+---
+
+## 3. State
+
+The dispatch script is **stateless per run**. All state lives in the Gitea API:
+
+| State | API location |
+|-------|-------------|
+| Open PRs | `GET /repos/:repo/pulls?state=open` |

+
+## 4. Output Protocol
+
+The script emits structured lines to stdout. Stderr is diagnostic logging.
+
+### `SPAWN:<type>:<number>:<sha>`
+
+A worker is needed. The cron model reads this and spawns a subagent using the
+template at `worker-tasks/<type>.md`.
+
+| Field | Description |
+|-------|-------------|
+| `type` | Worker type: `self-review`, `ci-fix`, `address-feedback`, `findings`, `rebase`, `impl` |
+| `number` | PR number (or issue number for `impl`) |
+| `sha` | HEAD SHA of the PR (empty for `impl`) |
+
+At most **one SPAWN** is emitted per script run.
+
+### `HANDOFF:<pr_num>`
+
+All checks passed for `pr_num`. The script applied the `ready` label and assigned
+to the human reviewer. The cron model logs this and takes no further action.
+
+Multiple HANDOFFs may be emitted in one run (one per qualifying PR).
+
+---
+
+## 5. Dispatch Rules
+
+Rules are evaluated **in order** for each open PR. The first matching condition wins.
+Only one SPAWN is emitted per full pass.
+
+### Rule 0: WIP Cleanup
+
+For each open PR with a `wip` label:
+
+1. Find the timestamp when the label was most recently applied (via timeline events)
+2. If age > 1hr: **remove the label** (stale lock — worker likely crashed)
+3. If age ≤ 1hr: **set ACTIVE_WIP=1** (do not exit, only gates Rule 10)
+
+### Rule 2: REQUEST_CHANGES Blocks
+
+**ALWAYS evaluated before any other per-PR rule.**
+
+For each reviewer, take their **latest** review state. If any reviewer's latest
+state is `REQUEST_CHANGES`:
+
+→ Acquire WIP label on this PR
+→ Emit `SPAWN:findings:<pr_num>:<head_sha>`
+→ Continue to next PR (but only one SPAWN total)
+
+This rule cannot be bypassed by any condition. There is no waiver mechanism.
+
+### Rule 3: Merge Conflicts
+
+If `mergeable == false`:
+
+→ Acquire WIP
+→ Emit `SPAWN:rebase:<pr_num>:<head_sha>`
+
+### Rule 4: CI Failure
+
+If CI state is `failure` or `error`:
+
+- If a fix plan comment exists for this HEAD SHA: **skip** (worker in progress)
+- Otherwise:
+
+→ Acquire WIP
+→ Emit `SPAWN:ci-fix:<pr_num>:<head_sha>`
+
+### Rule 5: Bot Reviews Missing
+
+For each configured `review_bot`, check whether a review body contains the
+sentinel `<!-- review-bot:<name> -->`.
+
+If any sentinel is missing: **wait** (continue to next PR, no SPAWN).
+
+### Rule 6: CI Pending/Unknown
+
+If CI state is `pending` or `unknown`: **wait**.
+
+### Rule 7: Self-Review
+
+Check for a self-review comment from the bot user against the current HEAD SHA:
+- Comment contains `Self-review against <head_sha>`
+
+Sub-cases:
+- **Missing**: No self-review comment →
+  → Acquire WIP, emit `SPAWN:self-review:<pr_num>:<head_sha>`
+- **Needs attention** (`Assessment: ⚠️`): Found, but has findings:
+  - Fix plan exists for HEAD SHA: skip
+  - No fix plan: → Acquire WIP, emit `SPAWN:sr-fix:<pr_num>:<head_sha>`
+- **Clean** (`Assessment: ✅ Clean`): Continue to Rule 8
+
+### Rule 8: Unacknowledged Bot Review Findings
+
+For each **current** (contains `Evaluated against <head_short>`) APPROVED bot review
+that has a findings table:
+
+A finding is **unacknowledged** if it does not appear as `Finding #N` in a fix plan
+comment from the bot user for this HEAD SHA.
+
+If any unacknowledged findings exist:
+- Fix plan exists: skip
+- No fix plan: → Acquire WIP, emit `SPAWN:address-feedback:<pr_num>:<head_sha>`
+
+### Rule 9: Unresolved Inline Diff Comments
+
+An inline diff comment is **unresolved** if:
+1. `in_reply_to_id` is null (top-level comment)
+2. `resolver` is null (not formally resolved)
+3. No other comment has `in_reply_to_id` pointing to this comment (no reply)
+
+If unresolved comments exist:
+- Fix plan exists: skip
+- No fix plan: → Acquire WIP, emit `SPAWN:address-feedback:<pr_num>:<head_sha>`
+
+### Rule 10: Handoff
+
+All rules above passed. Verify all bot reviews are current (contain `Evaluated against <head_short>`).
+
+If all current:
+- Apply `ready` label
+- Assign to `aweiker`
+- Emit `HANDOFF:<pr_num>`
+- Continue evaluating remaining PRs (do NOT exit)
+
+If already assigned to `aweiker`: skip (assume handoff was already performed; continue to next PR without emitting another HANDOFF).
+
+### Rule 11: New Issue Pickup
+
+Only runs if: no open PRs exist AND `ACTIVE_WIP == 0`.
+
+Fetch open, unassigned issues. Priority: bugs first, then by number ascending.
+
+Claim the issue (assign to bot user to prevent double-pick), then:
+→ Emit `SPAWN:impl:<issue_num>:`
+
+---
+
+## 6. Safety Invariants
+
+These are statically checked by `~/.openclaw/workspace/scripts/test/check-invariants.sh` and enforced in all changes:
+
+| ID | Invariant |
+|----|-----------|
+| S1 | Zero merge API calls in dispatch script (`/merge` does not appear) |
+| S2 | REQUEST_CHANGES check (Rule 2) appears before CI check (Rule 4) |
+| S3 | REQUEST_CHANGES check (Rule 2) appears before ready label application (Rule 10) |
+| S4 | No model/AI API references in dispatch script |
+| S5 | `set -euo pipefail` present |
+| S6 | Active WIP does not cause early exit (only sets ACTIVE_WIP flag) |
+| S7 | SPAWN:impl guarded by `ACTIVE_WIP == 0` check |
+| S8 | No merge calls in any worker template |
+
+---
+
+## 7. Error Handling
+
+| Error | Behavior |
+|-------|----------|
+| `curl` returns error | `set -euo pipefail` aborts script — no partial actions |
+| `jq` parse error | Script aborts |
+| Worker crashes | WIP label left on PR; stale WIP cleanup (Rule 0) removes it after 1hr |
+| Race: two crons fire | WIP mutex prevents double-dispatch for same PR |
+| `sessions_spawn` fails | Worker not spawned; WIP label orphaned → cleaned in 1hr |
+| Config file missing | Exit code 2 with error message |
+
+---
+
+## 8. Worker Templates
+
+Each worker receives a precise task description with substituted values:
+
+| Template | Trigger | Key job |
+|----------|---------|---------|
+| `self-review.md` | No clean self-review | Post self-review comment, remove WIP |
+| `sr-fix.md` | Self-review needs attention | Address self-review findings, push, remove WIP |
+| `ci-fix.md` | CI failing | Diagnose, fix, push, remove WIP |
+| `address-feedback.md` | Unacknowledged findings or inline comments | Address feedback, push, remove WIP |
+| `findings.md` | REQUEST_CHANGES present | Address REQUEST_CHANGES, push, remove WIP |
+| `rebase.md` | Merge conflicts | Rebase on main, push, remove WIP |
+| `impl.md` | New issue | Implement feature/fix, open PR |
+
+Workers **always** remove the WIP label on completion and reply `NO_REPLY`.
+
+---
+
+## 9. Fixes for Issues #144 and #145
+
+**Issue #144** (autonomous merge):
+The dispatch script contains no merge API calls anywhere. The `~/.openclaw/workspace/scripts/test/check-invariants.sh`
+invariant `S1` verifies this. Workers do not receive merge instructions.
+
+**Issue #145** (merged despite REQUEST_CHANGES):
+Rule 2 is the **first** rule evaluated per PR. It cannot be skipped, reasoned past,
+or bypassed. It is checked before CI, before self-review, before handoff. The check
+uses latest-per-reviewer state, so a reviewer who re-approved after REQUEST_CHANGES
+is correctly handled.
