## Executive Summary
10+
11+
Over the past week, ADF (AI Dark Factory) processed **30 unique PRs across 6 repositories**, posting **82 terminal commit statuses** (3 per PR gate set: `adf/pr-reviewer`, `adf/validation`, `adf/verification`). The orchestrator spawned **275 agent runs** across 20 different agent roles.
12+
13+
**20 PR gate timeout failures** occurred, all handled fail-closed via the `PrGateResult` contract. **10 agent exits** were classified as `unknown` (non-zero exit code, no pattern match). **7 rate-limit hits** and **3 crash/panic patterns** were detected.
14+
15+
The primary focus of the week was landing the native `PrGateResult` contract and native PR gate producer pipeline on `terraphim-ai` PR #2318, which went through **11 head commits** with iterative testing and live validation on bigbox.

#### PR #2318 Detailed Timeline
45+
46+
PR #2318 ("Fix #2301: add PrGateResult contract for PR fan-out gates") was the primary development focus:
47+
48+
| Commit | Description | Gate Outcome |
49+
|--------|-------------|-------------|
50+
| `b71332d` | Initial PR open | All 3 passed (`verdict already present for head`) |
51+
| `0e072ee` | `feat(orchestrator): add PrGateResult contract` | All 3 passed |
52+
| `073ede3` | `fix(orchestrator): discard PrGateResult drain-log parsing` | All 3 passed |
53+
| `88b008a6` | `fix(orchestrator): synthesise canonical failed PR gate results` | All 3 **failed** (malformed `adf:gate-result` JSON -- by design, validating fail-closed parse handling) |
54+
| `ca4a6f2ad` | `fix(orchestrator): fail closed on PR gate timeouts` | All 3 **failed** (`agent exceeded 300s PR gate wall-clock limit` -- by design, validating 300s timeout enforcement) |
55+
| `902f8167b` | `fix(orchestrator): harden native PR gate producer spawn` | All 3 passed (first native producer run) |
56+
| `2575c3604` | `fix(orchestrator): fetch PR refs for native gate evidence` | All 3 passed (107k-character native prompts) |
57+
| `900c00a88` | `fix(orchestrator): fetch PR gate evidence from head refs` | All 3 passed (`pass (4/5)` each) |
58+
| `866460a1e` | `docs(adf): record final PR gate validation` | **pr-reviewer: failure** (`2 blocking finding(s) reported`), validator/verifier: passed |
59+
60+
The final head (`866460a1e`) is blocked by the reviewer gate finding 2 blocking issues (truncated diff evidence and traceability gaps between a doc-only head commit and the implementation commits referenced in validation evidence).

## Failure Analysis
114+
115+
### Timeout Failures (20 events)
116+
117+
All 20 timeout failures occurred in the PR gate path and were handled fail-closed: the orchestrator posted a `failure` commit status on Gitea and a canonical `adf:gate-result` comment with `"status": "fail"` and `"summary": "agent exceeded 300s PR gate wall-clock limit"`.
118+
119+
Notable timeout clusters:
120+
- `ca4a6f2ad` (PR #2318 timeout validation test): All 3 gates intentionally timed out.
121+
- `ab0ecc1` (PR #2365): 2 of 3 gates timed out (pr-reviewer, pr-validator) at ~327s and ~327s.
122+
- Several `implementation-swarm` agents hit timeout patterns but recovered with `exit_class=success` (the pattern was matched but the agent completed successfully).
123+
124+
### Rate-Limit Failures (7 events)
125+
126+
Rate-limit patterns (`429`, `rate limit`, `ratelimit`) were matched in agent exits:
127+
- 3 PR gate agents hit rate limits (pr-verifier, pr-reviewer, pr-validator)
128+
- These were classified as `success` because the `exit_code` was 0; the rate-limit detection is informational.
129+
130+
### Crash/Panic Patterns (3 events)
131+
132+
- `pr-validator` on an earlier head: matched `crash` pattern, `wall_time_secs=670`.
133+
- `implementation-swarm`: 2 instances of non-zero exit code with `exit_class=unknown`.
134+
135+
### Unknown Exit Classifications (10 events)
136+
137+
Ten agent exits had non-zero exit codes with no matched error pattern:
138+
- `implementation-swarm`: 8 instances (exit_code=1, wall time ~27-30s)
139+
- `meta-learning`: 1 instance (exit_code=1, wall time ~30s)
140+
141+
These are typically CI runner pre-check failures (e.g. missing project workspace) rather than agent code bugs.
142+
143+
### Malformed-Output Failures (3 events, intentional)
144+
145+
- `88b008a6` (PR #2318): All 3 gates failed with parse errors on malformed `adf:gate-result` JSON. This was a deliberate live validation of the fail-closed parsing and canonical failure-envelope synthesis.
146+

## Auto-Merge Activity
172+
173+
The auto-merge subsystem scanned all configured projects throughout the week. No PRs were auto-merged; all required human review due to confidence scores below the 5/5 threshold. Notable patterns:
174+
175+
- **Stale verdicts**: Multiple projects (`atomic-server`, `odilo`, `terraphim-ai`) had PRs where the review SHA no longer matched the current head.
176+
- **Parse failures**: Several `terraphim-ai` PRs had reviewer comments that could not be parsed (missing confidence score headers, malformed footers), preventing auto-merge evaluation.
177+
- **Confidence distribution**: Reviewed PRs typically scored between 2/5 and 4/5; none reached the auto-merge threshold of 5/5.
178+
179+
---
180+
181+
## Platform Health
182+
183+
- **Service restarts**: The `adf-orchestrator.service` was restarted at least 4 times during the period (PID changes: `2252029` -> `1732284` -> `582580` -> `645542` -> `2130651`). These correspond to binary deployments for the PR #2318 iterative validation.
184+
- **Reconcile loop**: The reconcile tick typically completed in 300-1800ms but occasionally hit SLOW warnings (>5s) during repository auto-merge enumeration of the large `terraphim-ai` PR backlog (~292 open issues, ~85 open PRs).
185+
- **Telemetry lag**: Output event telemetry regularly reported skipped events for PR gate agents (typically 600-1900 events lagged per 30s interval), indicating the `pi-rust` CLI produces output faster than the orchestrator can drain during LLM inference.
186+
187+
---
188+
189+
## Key Observations
190+
191+
1. **Fail-closed handling validated**: The `PrGateResult` contract's malformed-output and timeout fallback paths were live-tested on PR #2318 commits `88b008a6` and `ca4a6f2ad`. Both correctly produced `failure` statuses and canonical fallback comments.
192+
193+
2. **Native PR gate pipeline operational**: Commits `902f8167b`, `2575c3604`, and `900c00a88` demonstrated the new native pipeline: orchestrator-built bounded prompts (~109k characters), `terraphim_automata` concept matching, head-ref-based evidence fetch, and terminal status posting from parsed `adf:gate-result` blocks.
194+
195+
3. **Reviewer false positive on current head**: The final doc-only commit (`866460a1e`) triggered a reviewer failure (2 blocking findings). The reviewer's concern about truncated diff evidence and traceability gaps is a limitation of the 60k-character comment truncation and the mismatch between the validation report's implementation-commit references and the doc-only head, rather than a code defect.
196+
197+
4. **Cross-repo coverage**: ADF PR gates are active across 6 repositories (`terraphim-ai`, `odilo`, `terraphim-clients`, `terraphim-agents`, `terraphim-kg-agents`, `terraphim-service`) covering the polyrepo split under the `terraphim` Gitea organisation.
198+
199+
5. **No GitHub ADF activity**: The `github.com/terraphim` organisation contains 60+ repositories but ADF gate statuses are posted only to Gitea, which is the authoritative CI and review platform.

# ADF Review: Worktree-Per-Agent Isolation
2+
3+
Issue: 2301
4+
Flow: adf-worktree-isolation-review
5+
Generated: 2026-05-29 20:20 BST
6+
Status: Completed
7+
8+
## Executive Summary
9+
10+
ADF reviewed the current `terraphim_spawner` and orchestrator worktree-related code against issue #1806's checklist. The system already has meaningful worktree isolation plumbing in the orchestrator: `create_agent_worktree()` runs `git worktree add --detach`, `WorktreeGuard::for_managed()` removes managed worktrees, and `ManagedAgent` retains the guard for the active agent lifetime.
11+
12+
The current state is therefore **partially implemented but not yet issue-complete**. The strongest review finding is that the worktree path is written into the provider's `working_dir`, but the actual `AgentSpawner` process directory is selected from `SpawnContext` first. `spawn_agent_with_event()` builds `spawn_ctx` from project config after computing `agent_working_dir`, so project-bound agents may still execute in the project root rather than the isolated worktree unless the provider conversion path overrides config working_dir before `spawn_process()`.
13+
14+
## Checklist Evaluation
15+
16+
| Requirement | Current Evidence | Verdict |
17+
|-------------|------------------|---------|
18+
| `git worktree add` before each pi-rust agent spawn | `create_agent_worktree()` runs `git worktree add --detach <path> HEAD` before provider construction | Mostly met |
19+
| Unique path per agent under `~/.cache/terraphim/agents/wt-<agent-id>-<timestamp>/` | Current path is `<repo>/.worktrees/<agent-name>-<uuid8>`, not the issue's cache-path convention | Partially met |
20+
| Cleanup after completion or graceful shutdown | `WorktreeGuard::for_managed()` supports `git worktree remove --force`; `ManagedAgent` stores the guard | Mostly met |
21+
| tmux session integration for attach/reprompt | No `tmux` references found in spawner or orchestrator source | Missing |
22+
| Fallback if worktree creation fails | `create_agent_worktree()` fail-opens to shared working_dir | Met, but should become policy-controlled |
23+
| Tests for concurrent isolation and cleanup on error | `worktree_guard` has cleanup tests; no proof found that spawned child processes actually run inside the worktree | Partially met |
24+
25+
## Highest-Risk Finding
26+
27+
The code appears to compute an isolated worktree path, then builds `spawn_ctx` independently from project config:
28+
29+
- `agent_working_dir = worktree_path.as_deref().unwrap_or(repo_dir).to_path_buf()`
30+
- Provider `working_dir` receives `agent_working_dir`
31+
- `spawn_ctx = build_spawn_context_for_agent(...)`
32+
- `spawn_process()` chooses `ctx.working_dir` before `config.working_dir`
33+
34+
If `spawn_ctx.working_dir` is set to the project root, it can shadow the provider `working_dir` and defeat the isolation. This is exactly the kind of cross-boundary contract bug issue #1806 is intended to flush out.
35+
36+
## Recommended Design
37+
38+
1. After `agent_working_dir` is computed, layer it into `spawn_ctx` with `SpawnContext::with_working_dir(agent_working_dir.clone())` semantics so the process current directory cannot diverge from the provider working directory.
39+
2. Add a regression test that spawns a simple local command and asserts `pwd` equals the created worktree path.
40+
3. Convert the fail-open behaviour to explicit policy: `Abort`, `SharedWorkingDir`, or `ReadOnlySharedWorkingDir`.
41+
4. Decide whether the issue's `~/.cache/terraphim/agents/...` path convention should replace the current repo-local `.worktrees/...` convention.
42+
5. Add optional `tmux new-session -d -s <session-id>` wrapping at the same orchestration boundary, not inside low-level output capture.
43+
44+
## Acceptance Tests To Add
45+
46+
- A spawned implementation-tier agent reports `pwd` equal to the created worktree path.
47+
- Two concurrently spawned agents write to different files and never touch each other's working directories.
48+
- Failed worktree creation returns a structured degraded-mode result or hard error according to config.
49+
- Dropping the guard after a simulated failed agent removes both filesystem path and git worktree registry entry.
50+
- Successful run can preserve the worktree when configured for inspection.
51+
- tmux session id is unique and stable enough for attach/reprompt.
52+
53+
## Implementation Slice
54+
55+
The smallest useful PR should avoid implementing full pi-rust orchestration. It should add only:
56+
57+
- spawn-context working directory override after worktree creation
58+
- a current-directory regression test proving the child actually runs in the worktree
59+
- policy-controlled fallback for worktree creation failure
60+
- one concurrent isolation test
61+
62+
This would turn the existing partial implementation into executable isolation behaviour without overreaching into model routing or agent lifecycle policy.
63+
64+
