server/src/agents/pool/lifecycle.rs and server/src/chat/transport/matrix/notifications.rs were untracked leftovers from an abandoned WIP stash that 'git add -A' picked up. Neither is declared as a mod anywhere — they're dangling code that doesn't get compiled but pollutes the tree.
The 13-file refactor pass (commits db00a5d4 through eca15b4e) introduced
~89 clippy errors and 38 cargo fmt issues — every agent in every worktree
hit them on script/test, burning their turn budget on cleanup before doing
real story work. This is the silent kill behind 644, 652, 655, 664, 667
all hitting watchdog limits this round.
Changes:
- cargo fmt --all across 37 files (formatting normalisation only)
- #![allow(unused_imports, dead_code)] on 24 split modules where the
python-script splitter imported liberally to be safe; tighter cleanup
per-import will happen as agents touch each module
- Removed truly-dead re-exports (cleanup_merge_workspace, slog_warn from
http/mcp/mod.rs, CliArgs/print_help from main.rs)
- Prefixed _auth_msg in crdt_sync/server.rs (handshake helper return is
bound but not consumed)
- Converted dangling /// doc block in crdt_sync/mod.rs to //! so it
attaches to the module
- Removed empty lines after doc comments in 4 spots (clippy lint)
All 2636 tests pass; clippy --all-targets -- -D warnings clean.
The biggest miss is #[tokio::main] — without it, async fn main() doesn't compile,
and the binary in every worktree fails 'cargo check'. Agents in those worktrees
burn their turn budgets trying to fix the build before they can do real work, then
get killed by the watchdog. That's why all three in-flight stories failed.
Other restored attributes:
- #[cfg(unix)] on 4 tests in merge/squash and scaffold (skip on non-Unix)
- #[allow(dead_code)] on AuthListenerResult test enum
- #[allow(clippy::too_many_arguments)] on run_pty_session
Same root cause as the earlier #[test] attribute losses: my line ranges started
at the fn line, missing the leading attribute on the previous line.
The 1630-line start.rs is split into a sub-module directory:
- validation.rs: validate_agent_stage + read_front_matter_agent helpers (69 lines)
- spawn.rs: run_agent_spawn — the background async work that was inlined as
a tokio::spawn closure body inside start_agent (359 lines)
- mod.rs: AgentPool::start_agent orchestrator + tests (1062 lines)
Stage validation and front-matter agent reading are pre-lock pure helpers that
naturally extract. The spawn closure body becomes a free async fn that takes
the previously-cloned values as parameters; rebound to the original _clone /
_owned names at the top of the body so the actual work code is a verbatim copy.
No behaviour change. All 23 start tests pass; full suite green.
The 1353-line advance.rs is split into:
- mod.rs: impl AgentPool with run_pipeline_advance + start_mergemaster_or_block + tests (1244 lines)
- helpers.rs: spawn_pipeline_advance, resolve_qa_mode_from_store, write_review_hold_to_store, should_block_story (128 lines)
Tests stay co-located with run_pipeline_advance which they exercise.
No behaviour change. All 10 advance tests pass; full suite green.
The auto-resolver kept both sides of the conflict — feature's
_project_root signature with master's filesystem code referencing
project_root — producing a compile error. Remove the filesystem
fallback on master so there's no conflict. CRDT is the only source
of truth.

cargo fmt without --all fails with "Failed to find targets" in
workspace repos. This was blocking every story's gates. Also ran
cargo fmt --all to fix all existing formatting issues.

Use fsync in coverage gate tests to ensure the kernel releases the
write handle before executing the script. Prevents flaky ETXTBSY
errors on fast test runs.

The completion handler now pgrep+kills any cargo processes targeting
the worktree's Cargo.toml before running gates. This prevents the
run_tests MCP child from holding the build lock and blocking gates.

run_tests MCP tool now spawns tests in the background and returns
immediately. Agents poll get_test_result to check completion. This
prevents zombie cargo processes from holding the build lock when the
CLI times out the MCP call before tests finish.
Also fixes agent permission mode: acceptEdits replaces invalid
allowFullAutoEdit that was causing agents to crash-loop on spawn.

bypassPermissions ignored the worktree's .claude/settings.json entirely,
letting agents run any Bash command including cargo test (which they'd
spawn 4+ times concurrently, deadlocking on the build directory lock).
allowFullAutoEdit respects the settings.json allowlist, so agents can
only use the Bash commands we explicitly permit (cargo check, cargo
build, git) and must use MCP tools for everything else (run_tests,
run_lint, run_build).

The mergemaster agent was burning all 30 turns polling get_merge_status
every 2 seconds while the merge pipeline takes ~2 minutes. It would
exhaust turns, exit, restart, and repeat — never seeing the result.
merge_agent_work now blocks with a 10-second internal poll loop and
returns the final result directly. The agent calls it once and gets
the answer. No more polling turns wasted.

When an agent CLI exits without creating a session, we now log:
- Number of prior sessions and total session log bytes
- Child process exit status (exit code or signal)
- Explicit SESSION NONE warning with context
This will help diagnose whether the fatal runtime error
(output.write assertion) correlates with accumulated sessions,
budget exhaustion, or something else.
