855 deleted the HTTP /mcp route and pointed agents at ws://...crdt-sync,
but Claude Code's .mcp.json doesn't speak ws:// and the rendezvous WS
never had MCP method handlers wired up — so every spawned Claude Code
agent (gateway-routed and local) booted with zero huskies tools and
died on --permission-prompt-tool=mcp__huskies__prompt_permission.
Restore mcp_post_handler / mcp_get_handler / handle_initialize, re-add
the /mcp route, and revert all three .mcp.json writers to emit
http://localhost:{port}/mcp with explicit "type": "http". Reuses the
already-extracted gateway::jsonrpc types and the surviving
dispatch_tool_call / list_tools surfaces — net add ~140 lines.
Federation work is unaffected: /crdt-sync continues to do CRDT sync,
which is what it was actually doing. MCP-over-WebSocket for cross-LAN
agents was never wired up by 855 and can be done as a proper follow-up
with a regression test that boots a real claude and verifies tool
registration.
Verified end-to-end: /mcp initialize, tools/list (74 tools incl.
prompt_permission), and tools/call all respond correctly from inside
the rebuilt container.

The merge_jobs cleanup encoded the server's pid in the CRDT and checked
`kill(pid, 0)` to decide whether a "running" entry was stale. Two problems:
1. The cleanup runs *inside* the server, so checking whether the
server's own pid is alive is tautological — kill(self_pid, 0)
always succeeds.
2. `rebuild_and_restart` does an `execve()` re-exec, which keeps the
same pid. After re-exec, merge_jobs from the previous server
instance still encode "the current pid" — so the cleanup never
fires, and stories like 799/800 sit forever with status="running"
while no actual merge runs.
Switch to a per-process server-start-time captured lazily in a
`OnceLock<f64>` (reset by execve, so the new instance sees a fresh
boot-time). A merge_job's recorded start-time < current boot-time means
it came from a previous instance: stale, delete it.
Legacy pid-encoded entries decode to None and are also treated as stale.
MergeJob.pid → MergeJob.server_start_time. Tests updated.
claude CLI 2.1.97 strictly enforces that --include-partial-messages
requires --print/-p to be set. The resume path skipped -p when the
prompt was empty (which is the common case on respawns when there's
no fresh failure context to inject), so the spawned claude process
saw `--resume <sid> ... --include-partial-messages` without -p and
exited with code 1: "include-partial-messages requires --print and
--output-format=stream-json".
Net effect: every coder respawn with prior_sessions > 0 and empty
prompt was failing immediately, looking exactly like a rate-limit
(empty agent log, zero tool calls). 819 hit retry-limit (4/3) and
got marked blocked because of this — not because of any actual code
or rate-limit issue.
Fix: always pass `-p <prompt>` on resume, even with empty prompt.
770's HTTP→read-RPC migration replaced fetch-based agent calls with
rpcCall over WebSocket. setupTests.ts only mocks fetch though, so the
real jsdom WebSocket runs — and jsdom's WebSocket implementation
asynchronously fires its connection-failure error after ~9 seconds
(via internal Timeout._onTimeout). Tests that await component-mount
state (like App.test.tsx > calls getCurrentProject() on mount) hang
on that pending promise and time out at 10s.
This silently broke 1 test on master (App.test.tsx getCurrentProject
on mount) and cascaded into 16 failures in any worktree where the
test file count changed and timing shifted (804, 806).
Fix: replace the global WebSocket constructor with a stub that
immediately fires onerror + onclose on the next microtask. rpcCall
sees the error and rejects synchronously; components catch and continue
rendering with empty state. Tests pass without flake.
Verified locally: vitest run → 349/349 pass.
Tests that create temp repos call `git init` without specifying a branch.
Git then prints a 12-line "hint: Using 'master' as the name for the
initial branch..." block — every test, every run. The output drowns out
actual failures.
Set init.defaultBranch=master via GIT_CONFIG_COUNT/KEY/VALUE env vars in
script/test. This affects only subprocesses spawned by the test runner;
no change to the user's real git config.
Verified: cargo test --bin huskies emits 0 `hint:` lines after this
change, all 2732 tests still pass.
`tool_run_tests` in `server/src/http/mcp/shell_tools/script.rs` is fully
blocking server-side: it spawns the test child, polls every 1s server-side
until exit (or `TEST_TIMEOUT_SECS = 1200s`), and returns the full
{passed, exit_code, output} directly. There is NO async/started-status
return path.
But two places told agents the wrong story:
1. `tools_list/system_tools.rs` description claimed "Returns immediately
with status: started. Poll get_test_result..." — agents read tool
descriptions for protocol semantics, so they followed this and burned
turns polling get_test_result.
2. `agents.toml` had been correctly saying it blocks, but my last commit
(776aad38) "fixed" it the wrong way based on a misread of the code.
Now both say: run_tests blocks server-side, returns the full result, do
not poll get_test_result. get_test_result remains for external observers
(UI checking on a job another caller started).
Reverts the prompt change in 776aad38 with the correct text.
Pre-f958f57e, run_tests blocked until completion. After that fix it became
a background-job starter, with get_test_result polling. The agent prompts
were never updated, so they still said "run_tests blocks until complete"
— and agents then waste turns polling.
Updated coder-1/2/3, coder-opus, and qa prompts to describe the actual
flow: run_tests is async, get_test_result blocks for up to 20s per call,
test suites typically take 1-5 minutes so expect a few polls.
Companion bug filed for bumping TEST_POLL_BLOCK_SECS so one poll covers
most test runs (root-cause fix; this commit is the prompt half).
Walked server/src/, frontend/src/, and crates/, extracting each module's
//! doc-comment to build a directory-level source map. One row per
directory + one row per top-level file.
Replaces the hand-written stopgap from 5d6757dd with content auto-derived
from the codebase, so it stays useful as decomposes happen — the
descriptions come from mod.rs, not from my recollection of where things
live.
Still a stopgap until 819 (auto-generated source-map-gen) lands and gets
wired into the agent spawn path, but the content is closer to what 819
will produce.
818 stripped the source map because it had stale paths. Empirically that
made coder agents far slower — they spent most of each session re-discovering
the codebase via Read/Grep before reaching any Edit, and ran out of turn
budget without committing.
Restoring a fresh source map keyed off current master. Uses directories
where possible so it stays useful through future decomposes, plus a
"Canonical examples" section pointing at the patterns to copy when adding
new CRDT collections, RPC handlers, services, chat commands, etc.
This is a stopgap until 819 (auto-generated source-map-gen) lands.
Manual merge resolution: feature branch deleted watcher.rs and split
into watcher/{mod,events,sweep,tests}.rs, while master modified the
old watcher.rs (738's FS-shadow stripping). The auto-resolver kept
both, producing an ambiguous-module compile error.
Resolution: drop watcher.rs (feature's delete wins). The new
watcher/mod.rs absorbs the FS-shadow code semantically — gates pass
(cargo check, clippy --all-targets -D warnings, fmt --check, 29/29
io::watcher tests).

Mergemaster needs more headroom for heavy merges (e.g. the slug-to-numeric
ID migration touching many files, or the FS-shadow deletion stories that
require fixing test setup across the codebase). 60 turns wasn't enough
for the larger ones.

- Append to all coder/opus system_prompts: for delete/signature-change
refactors, delete first and let compiler errors guide the call-site
walk; do not pre-read files predicting breakage. Reduces exploration
overhead on mechanical refactors.
- Bump mergemaster inactivity_timeout_secs 300 -> 900 (15 min) so
mergemaster survives the 5-minute API rate-limit backoff. Without
this, mergemaster gets killed for inactivity while waiting on rate
limit clear, blocking all merges.

Stories like the broadcaster-consumer migrations legitimately need ~60
substantive turns (16 ProjectConfig initializer sites + main.rs subscriber
+ reading existing patterns to mirror). 50 was too tight.

Full inventory of all gateway and project server endpoints with caller,
purpose, latency/freshness/durability requirements. Classifies each as
write/read/external-webhook/frontend-asset. Maps write endpoints to
target CRDT collections, proposes RPC frame shapes for read endpoints,
drafts the unsigned read-RPC protocol (envelope, correlation IDs, TTL,
error codes, peer-offline handling), lists in-memory state needing CRDT
migration with proposed types, and defines a wave-ordered migration plan
with explicit dependencies (story 665 Ed25519 auth as the blocker for
write migrations).
Master had 8 uncommitted single-line whitespace changes (blank-line trimming
in test mod headers, etc.) left over from a previous mergemaster cargo-fmt
run that didn't get committed. Each subsequent merge attempt hit:
cherry-pick failed: 'Your local changes to the following files would be
overwritten by merge. Please commit your changes or stash them.'
So merges had been silently un-mergeable for the last several rounds —
mergemaster correctly reported the issue but had no way to fix master's
own state from inside the merge_workspace.
Files affected (all whitespace-only):
- chat/transport/matrix/bot/messages/{handle_message,on_room_message}.rs
- chat/transport/slack/commands/{llm,mod}.rs
- http/mcp/agent_tools/worktree.rs
- http/workflow/story_ops/{create,criterion,update}.rs
cargo clippy --all-targets -- -D warnings: clean
cargo fmt --all --check: clean
2636 tests pass.
Real cause of mergemaster turn-burnout: not merge conflicts, just polling
overhead. The server-side tool_merge_agent_work IS designed to block until
the merge completes, but the MCP client times out after 60s. The agent
then polls get_merge_status, with 30-60s sleeps between polls — each
poll cycle costs 2 turns (sleep + tool call). The merge takes 5-10 min
for a clean run, so the agent burns 10-20 turns just waiting.
Updated workflow tells mergemaster:
- 'operation timed out' is normal, do NOT immediately re-call (would queue
a duplicate merge)
- Use Bash sleep 300 (one 5-min wait = 1 turn) between polls
- Cap at 3 polls = 15 minutes total, plenty for any clean merge
- Reserve turns for actual fix-up work if gates fail
Combined with the earlier 30→60 turn / $5→$15 budget bump, this should
land any merge with no real conflicts in 3-5 turns total. Plenty of
headroom remaining for genuine gate-fix work.
30 turns is too tight for non-trivial merge gate failures. Combined with
the 3-retry cap, stories with any post-merge fix-up needed (cargo fmt
nits, slightly out-of-date diffs after parallel merges, etc.) get
permanently blocked.
This is a stopgap until story 668 lands (which will keep gates_passed=false
work in the coder stage entirely, so mergemaster only ever sees clean
diffs and the original 30 turns / $5 is fine again).
Replaces the test-time GLOBAL_STATE_LOCK approach (which was just disguised
single-threading) with proper test isolation: each test thread gets its own
SnapshotState via a thread_local!.
Pattern matches crdt_state::CRDT_STATE_TL — production keeps the global
OnceLock; tests get a per-thread OnceLock that's accessed through a
snapshot_state() helper. The unsafe `&*ptr` cast to 'static is safe because
the thread_local lives as long as the spawning test thread.
The race: latest_snapshot_available_after_compaction captured at_seq from a
freshly-generated snapshot, then asserted it equalled SNAPSHOT_STATE's
latest.at_seq. With shared SNAPSHOT_STATE, another test thread's
apply_compaction could overwrite latest_snapshot between capture and read.
Per-thread state eliminates the race at its source.
ALL_OPS / VECTOR_CLOCK stay shared — the tests don't assert on absolute
counts, only on (this-thread's at_seq) == (this-thread's latest.at_seq).
5 consecutive default-parallel `cargo test --bin huskies` runs all green
at 2636/2636.
The crdt_snapshot tests share three global statics:
- SNAPSHOT_STATE (latest_snapshot, pending_acks, pending_at_seq) — coordination state
- crdt_state::ALL_OPS / VECTOR_CLOCK — op journal + vector clock
Only the per-thread CRDT is thread-local (init_for_test); these other globals
are shared across test threads. Under default cargo test parallelism, two tests
running concurrently interleave their op writes and snapshot generation, so
assertions like assert_eq!(at_seq, 4) fail with at_seq=5 (the other thread's
ops snuck in).
Add a module-level GLOBAL_STATE_LOCK that all 17 affected tests grab at the
top. unwrap_or_else(|e| e.into_inner()) handles the case where a prior test
panicked while holding the lock (poisoned).
Fixes bug 669 — these two tests were the silent killer behind every agent's
script/test failure (see also bug 668, which advanced agents to merge despite
gates_passed=false; that compounded this by sending failing-tests worktrees
to mergemaster).
All 2636 tests now pass under default parallel execution (no --test-threads=1
needed).
Closes#669.
The 861-line diagnostics.rs is split:
- permission.rs: tool_prompt_permission + helpers + their tests (584 lines)
- usage.rs: tool_get_token_usage + tests (122 lines)
- mod.rs: server_logs, rebuild, version, loc_file, dump_crdt, move_story + tests (185 lines)
Tests stay co-located. The bigger sub-modules (permission at 584 with tests
mostly under 800; usage at 122) are well within the 800-line guide.
Also added #[allow(unused_imports)] to two now-pedantic re-exports in
service/diagnostics/mod.rs that the split made flag.
All 2636 tests pass; clippy clean.
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.
Same root cause as 0d805313: when extracting a test that's the FIRST inside its
mod block, the slicer started at the fn line and missed the leading #[test]
attribute on the previous line. Test count now matches pre-split count (2636).
Lost in commit db00a5d4 when extracting tests from main.rs into cli.rs;
the line range used for the panics_on_duplicate_agent_names test in main.rs
started at the fn signature instead of the attribute line.
The 1680-line server.rs is split:
- handshake.rs: perform_auth_handshake helper + close_with_auth_failed + auth tests
+ start_auth_listener / close_listener_auth_failed test helpers + AuthListenerResult enum
- server.rs: crdt_sync_handler (now invokes perform_auth_handshake) + wait_for_sync_text
+ broadcast/e2e/keepalive tests
Auth handshake (Steps 1-3 of the WebSocket handshake) is a self-contained sequence
that takes &mut SplitSink + &mut SplitStream and returns Option<AuthMessage>. The
caller observes None to mean the connection has already been closed with the
appropriate close code.
No behaviour change. All 63 crdt_sync tests pass; full suite green.
The 1258-line main.rs is split into:
- main.rs: mod declarations, async fn main + panics_on_duplicate_agent_names test (894 lines)
- cli.rs: CliArgs struct, parse_cli_args, print_help, resolve_path_arg + their tests (372 lines)
main.rs cannot itself become a directory (binary crate must have main.rs at the
crate root); cli.rs is a sibling module.
No behaviour change. All cli 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 1864-line story_tools.rs is split into:
- story.rs: story creation/lifecycle/management (903 lines incl. tests)
- criteria.rs: acceptance-criteria tools (534 lines)
- bug.rs: bug item tools (318 lines)
- spike.rs: spike item tools (120 lines)
- refactor.rs: refactor item tools (60 lines)
- mod.rs: re-exports (25 lines)
Tests stay co-located with the code they exercise; setup_git_repo_in and
setup_story_for_update test helpers are duplicated into the modules that need
them rather than centralised, since they are tiny and test-only.
No behaviour change. All 60 story_tools tests pass; full suite green
(2635 tests with --test-threads=1).
The 1882-line mod.rs is split into:
- tools_list.rs: handle_tools_list — the static schema for every MCP tool (1172 lines)
- dispatch.rs: handle_tools_call — the tool-name → *_tools router (157 lines)
- mod.rs: doc, sub-mod decls, JsonRpc structs, Poem handlers, handle_initialize (586 lines)
Tests stay co-located with the code they exercise.
No behaviour change. All 267 http::mcp tests pass; full suite green
(2635 tests with --test-threads=1).
The 2045-line scaffold.rs is split into a sub-module directory:
- templates.rs: STORY_KIT_* and DEFAULT_* template constants (161 lines)
- detect.rs: detect_components_toml + detect_script_{build,lint,test} + tests (989 lines)
- helpers.rs: write_*_if_missing, generate_project_toml, gitignore helpers (166 lines)
- mod.rs: scaffold_story_kit orchestrator + scaffold tests (756 lines)
include_str! paths in templates.rs are adjusted (one extra ../) for the deeper
nesting. Tests stay co-located with the code they exercise per Rust convention.
No behaviour change. All 77 scaffold tests pass; full suite green
(2635 tests with --test-threads=1).
Five files in server/src/ exceeded 1500 lines, with 50–75% of the line
count being inline `#[cfg(test)] mod tests { ... }` blocks. Agents
working on these files have to navigate huge buffers via Read calls,
costing turn budget that could go toward actual work.
Pattern: convert `foo.rs` to `foo/mod.rs` + `foo/tests.rs`.
Rust resolves `mod foo;` to either form, so no parent-module changes
needed.
Before / after (production-code lines, what an agent has to navigate
when editing the module):
crdt_sync.rs: 3672 → 1003 (mod.rs) + 2667 (tests.rs)
crdt_state.rs: 2122 → 1263 (mod.rs) + 854 (tests.rs)
io/fs/scaffold.rs: 2045 → 702 (mod.rs) + 1342 (tests.rs)
http/mcp/mod.rs: 1882 → 1410 (mod.rs) + 472 (tests.rs)
http/mcp/story_tools.rs: 1864 → 725 (mod.rs) + 1137 (tests.rs)
Side change: scaffold/mod.rs's include_str! paths got an extra `../`
because the file moved one directory deeper.
Tests: full `cargo test` suite passes (2635 passed, 0 failed).
Formatting: cargo fmt --check clean.
Motivation: today's agent thrashing on 644 / 650 / 652 was partly due to
cumulative-counting (now fixed by 650) but also genuinely due to file
size — sonnet's 50-turn budget barely covers reading these files plus
making the change. Smaller production-code files mean more turn budget
left for the actual work.
Committed straight to master because this is an enabling refactor for
agent autonomy work; running it through the normal pipeline would
require an agent that has to navigate the very files it's about to
split, defeating the purpose.
Captures the dual representation we have today (legacy filesystem stage
strings + front-matter flags vs the typed Stage/ArchiveReason/ExecutionState
enums in pipeline_state.rs that are defined-but-not-wired) and itemises the
transitions and behaviours we have identified as missing or partially
implemented (first-class supersede/abandon/hold verbs, type-conversion side
effects, pinned-agent honouring under contention, blocked-flag enforcement
beyond auto-assign, ghost-story recovery, etc.).
Section (b) is intended as a living dumping ground — append new
transitions and incidents as they come up so that the state-machine
roadmap (spike 613 in backlog) has a ready-made input.
Documents current state and recommended next steps across four layers:
- Service layer: 21 modules extracted, remaining work in http/ws.rs and http/mcp/
- Chat transports: 4 backends (Matrix/Slack/WhatsApp/Discord), Bug 501 noted
- Pipeline state machine: typed enum in place, consumer migration (Story 520) remaining
- CRDT: source-of-truth migration ongoing, cleanup stories 511/513/517/518/519/521 prioritised
Phases A–E chart the dependency order: state machine → transport registry →
CRDT cleanup → cryptographic auth → build agent polish.
In gateway mode the bot's Claude Code CLI was spawned with cwd set to
a nonexistent project subdirectory (gateway_config_dir/project_name).
This meant it couldn't find .mcp.json and had no MCP tools available.
Now the bot uses the gateway config directory as cwd in gateway mode,
where the auto-generated .mcp.json points to the gateway's MCP proxy.
Also fixes cargo fmt formatting.

The gateway proxy was sending every message's first word to the project
server's /api/bot/command endpoint, then displaying the "Unknown command"
response before falling through to the LLM. Now the proxy only fires
when the first word matches a known bot command.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
In gateway mode the bot has no local CRDT or project filesystem, so all
bot commands (status, backlog, start, assign, etc.) returned empty or
broken results. Now the gateway bot proxies non-local commands via HTTP
to the active project's /api/bot/command endpoint, which already exists
on every project server.
Only a small set of gateway-local commands (help, ambient, reset, switch)
are still handled directly by the gateway. Everything else is forwarded
automatically, so new commands added in the future will work through the
proxy without additional gateway changes.

run_tests now spawns the child and blocks in a 1-second poll loop until

run_tests MCP tool now spawns tests in the background and returns

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).

Agents were running cargo test directly via Bash instead of using the

commands. Agents must use the run_tests MCP tool which returns truncated
output and prevents concurrent builds.

The mergemaster agent was burning all 30 turns polling get_merge_status

The sync_crdt_stages_from_db migration reads pipeline_items (which has
stale 5_done stages) and overwrites the CRDT back to 5_done for stories
that were already swept to 6_archived. On every restart, done stories

Tests shared a global CRDT singleton and content store HashMap, causing
flaky failures when parallel tests wrote items that polluted each
other's assertions. 3-5 random test failures per run.
Both CRDT_STATE and CONTENT_STORE now use thread_local! in test mode
so each test thread gets its own isolated instance. Production code
is unchanged — it still uses the global OnceLock singletons.
Also fixed 3 tests (create_story_writes_correct_content,
next_item_number_increments_from_existing_bugs,
next_item_number_scans_archived_too) that relied on leaked state
from other tests — they now write to the content store explicitly.
Result: 1902 passed, 0 failed across 5 consecutive runs.

Agents were running script/test directly through the PTY, streaming
the full output of npm install, cargo clippy, cargo test, and frontend
builds into session logs. This tripled session log sizes (~200KB to
~600KB per session) and contributed to CLI SIGABRT crashes.
The run_tests MCP tool already runs script/test server-side and returns
a truncated JSON summary. Agents now use it exclusively.

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

budget exhaustion, or something else.

The rate limit auto-scheduler was creating timers for every hard block,
including short 5-minute throttles. This caused a death loop: agent hits
rate limit, timer set, agent exits, pipeline restarts before timer fires,
new agent dies instantly (Session: None) because API is still throttled.
Short rate limits are handled naturally by the CLI's internal wait. Only
schedule timers for long session-level blocks (>10 min) where the CLI
will exit and needs external restart.

When replaying old CRDT ops that predate new struct fields (e.g.
claimed_by, claim_ts added by story 479), node_from would call

510 stories had stale 1_backlog stages in the CRDT because they were
imported during the filesystem→CRDT migration and then moved forward
via filesystem-only moves that never wrote CRDT ops. This made done

corrects any CRDT entries that disagree.

read_all_items was iterating all CRDT entries including stale duplicates
from earlier stage writes. A story written multiple times (backlog →
current → done) would appear in the output multiple times with different
stages, causing ghost entries in the pipeline status and backlog views.

represents the latest-wins deduplicated view of each story.

The post-520 migration changed validate_story_dirs to read from
pipeline_state::read_all_typed() (the process-global CRDT singleton),
ignoring its root: &Path argument. This broke test isolation — tests
creating a tempdir saw dozens of results from ambient CRDT state,
causing non-deterministic failures that blocked every mergemaster gate.
Remove the CRDT singleton block and rely on the filesystem shadow scan
that already uses the root argument correctly. 1845/1845 tests pass.

Adds the foundational capability to clear a story from the running
server's in-memory CRDT state without restarting the process. This is
story 521, motivated by the 2026-04-09 incident where stories 478 and
503 kept resurrecting from in-memory CRDT after every sqlite delete /
worktree removal / timers.json clear. The only previous remedy was a
full docker restart.
Changes:
- server/src/crdt_state.rs: new `pub fn evict_item(story_id: &str)`.
Looks up the item's CRDT OpId via the visible-index map, calls the
bft-json-crdt list `delete()` primitive to construct a tombstone op,
runs it through the existing `apply_and_persist` machinery (which
signs, applies to the in-memory CRDT, and queues for persistence to
crdt_ops), rebuilds the story_id → visible_index map, and drops the
in-memory CONTENT_STORE entry. The tombstone survives a restart
because it's persisted as a real CRDT op.
- server/src/http/mcp/story_tools.rs: new `tool_purge_story` MCP
handler that takes a story_id and calls evict_item. Deliberately
minimal — does NOT touch agents, worktrees, pipeline_items shadow
table, timers.json, or filesystem shadows. Compose with stop_agent,
remove_worktree, etc. for a full purge. Story 514 (delete_story
full cleanup) is the future "do it all" tool.
- server/src/http/mcp/mod.rs: registers the `purge_story` tool in the
tools list and dispatch table.
Usage:
mcp__huskies__purge_story story_id="<full_story_id>"
Returns a string confirming the eviction. The story will no longer
appear in get_pipeline_status, list_agents, or any other API that
reads from the in-memory CRDT view, and on the next server restart
the persisted tombstone op will keep it from being reconstructed.
This is a prerequisite for story 514 (delete_story full cleanup) and
useful for any "kill it with fire" operator need.

Bundles in-progress work from a parallel Claude session toward fixing
bug 501 (rate-limit retry timer doesn't cancel on stop_agent / move_story
/ successful completion). This commit lands the foundation but the MCP
tool wiring is still TODO.
- server/src/chat/timer.rs: defense-in-depth check in tick_once that
skips firing a timer for stories already past 3_qa (3_qa, 4_merge,
5_done, 6_archived). The primary cancellation path will be in the
MCP tools; this guards races where a timer was scheduled before the
story was advanced and the tool didn't get a chance to cancel it.
- server/src/http/context.rs: adds `timer_store: Arc<TimerStore>` field
on AppContext so MCP tools (move_story, stop_agent, ...) can reach
the shared timer store and cancel pending entries when the user
intervenes manually. The test helper is updated to construct one.
- server/src/main.rs: wires up a TimerStore instance in the AppContext
initialiser so the binary actually compiles after the context.rs
field addition. TODO: the matrix bot's spawn_bot still creates its
own TimerStore instance (in chat/transport/matrix/bot/run.rs:220-227)
rather than consuming the shared one — that refactor is the next
step in the bug 501 fix.
What is NOT in this commit and is needed to actually fix bug 501:
- The MCP tool side (move_story, stop_agent, delete_story) does not
yet call timer_store.cancel(story_id) when invoked
- The matrix bot's spawn_bot does not yet consume the shared
timer_store from AppContext — it still creates its own

The statig version was missing the per-node ExecutionState machine that
the bare version has. This commit adds it as a sub-module so its
generated `State` enum doesn't collide with the top-level PipelineMachine's
`State` enum.
Adds:
- ExecutionEvent enum (top-level, alongside PipelineEvent)
- mod execution { … } sub-module containing ExecutionMachine
- States: idle, pending, running, rate_limited, completed
- Cross-cutting `any` superstate that handles Stopped/Reset → Idle
- 6 new tests covering the happy path, rate-limit + resume, and
stop-from-anywhere via the superstate
Also adds a small note about how statig's `#[action]` entry/exit hooks
would replace the bare version's external EventBus pattern (without
implementing it — we'd pick one or the other based on whether side
effects should live inside or outside the state machine).
Test count: 11 → 17 (all passing).

Adds the markdown shadows for stories filed during today's stress-test
session, plus a SESSION_HANDOFF document for picking up the work in
a future session.
New stories (510-521):
510 — bug: stale 1_backlog filesystem shadows get re-promoted by timers
511 — bug: CRDT lamport clock resets to 1 on restart (FIXED in 99557635)
512 — story: migrate chat commands from filesystem lookup to CRDT/DB
513 — story: startup reconcile pass for state-machine drift detection
514 — story: delete_story should do a full cleanup
515 — story: debug MCP tool to dump in-memory CRDT state
516 — story: update_story.description should create the section if missing
517 — story: remove filesystem-shadow fallback paths from lifecycle.rs
518 — story: apply_and_persist should log persist_tx send failures
519 — story: mergemaster should fail loudly on no-op merges (mostly
obviated by Stage::Merge { commits_ahead: NonZeroU32 } in 520)
520 — story: typed pipeline state machine in Rust (sketches added in f7d69cde)
521 — story: MCP capability to write a CRDT tombstone for a story
Refactor 436 (unify story stuck states) is marked superseded by 520
via front_matter — its functionality is now part of the
Stage::Archived { reason: ArchiveReason } enum in story 520's design.
The SESSION_HANDOFF_2026-04-09.md document captures: the four-state-machine
drift situation that motivated story 520, today's bug fixes (502 + 511),
the off-leash rogue commit incident (forensic tag rogue-commit-2026-04-09-ac9f3ecf
preserved), the recommended next-session priority order, and useful
diagnostic recipes.

Two parallel scratch experiments under server/examples/ exploring the
typed Rust state machine that should replace huskies's current
stringly-typed CRDT representation (story 520).
- pipeline_state_sketch_bare.rs — hand-rolled, plain enums + match
- pipeline_state_sketch_statig.rs — using the statig crate
Both sketches:
- Define the same Stage enum (Backlog, Coding, Qa, Merge, Done, Archived)
- Define ArchiveReason (subsumes refactor 436's blocked/merge_failure/review_hold)
- Define ExecutionState (per-node, separate from synced Stage) — bare only
- Define PipelineEvent and the valid transitions
- Make bug 519 unrepresentable: Stage::Merge requires NonZeroU32 commits_ahead
- Make bug 502 unrepresentable: Coder agents can't be assigned to Merge state
- Have happy-path tests, retry-loop tests, and invalid-transition tests
Differences:
- Bare uses pure pattern matching, no framework. ~720 lines.
- Statig uses #[state_machine] proc macro and gets free hierarchical
states via the `active` superstate that factors out the cross-cutting
Block / ReviewHold / Abandon / Supersede transitions across the four
active stages. ~440 lines, 11 passing tests.
Run with:
cargo run --example pipeline_state_sketch_bare -p huskies
cargo run --example pipeline_state_sketch_statig -p huskies
cargo test --example pipeline_state_sketch_bare -p huskies
cargo test --example pipeline_state_sketch_statig -p huskies
Adds statig 0.3 as a dev-dependency in server/Cargo.toml. Cargo.lock
updated to include statig + statig-macro and their transitive deps.
Not wired into the main codebase. Once we agree on which version to
adopt, story 520 promotes the chosen sketch into a real
server/src/pipeline_state.rs module.

The CRDT lamport seq is per-author and per-field, not globally
monotonic. Replaying by `seq ASC` causes field-update ops (which
have low per-field seq counters like 1, 2, 3) to be applied
BEFORE the list-insert ops they reference (which have higher
per-list seq counters like N for the Nth item ever inserted).
The field updates fail with ErrPathMismatch because the target
item doesn't exist yet, the field counter is never advanced,
and subsequent writes silently lose state.
Concretely on 2026-04-09 we observed: post-restart writes were
being persisted at seq=1,2,3,4,5,6,7 even though pre-restart
seq had reached 492. On the next replay, those low-seq field
updates would be applied before their seq=485+ creation ops,
silently dropping the updates. This was the load-bearing
"why does state keep flapping" bug today.
Fix: replay by `rowid ASC` (SQLite insertion order) instead.
Rowid preserves the causal order ops were originally applied
in, so field updates always come after the item insert they
reference.
Adds a regression test that constructs the exact scenario:
inserts a story (op gets seq=6), updates its stage (op gets
seq=1 because field counter starts at 0), persists both ops
in causal order, then replays both seq ASC (reproduces the
bug — stage update is lost) and rowid ASC (the fix — stage
update is preserved).

Manual squash-merge of feature/story-478_… into master after the in-pipeline
mergemaster runs failed silently. The 478 agent did substantial real work
across multiple respawn cycles before being interrupted; commits on the
feature branch were intact and verified high-quality but never merged via
the normal pipeline path due to compounding bugs:
- The first mergemaster attempt ran ($0.82 in tokens) and exited "Done"
cleanly but didn't push anything to master — likely the worktree was
briefly on master rather than the feature branch when the merge_agent_work
MCP tool ran, so it found nothing to merge.
- Subsequent timer fires defaulted to spawning coders instead of resuming
mergemaster, burning more tokens for no progress.
- Bug 510 (split-brain shadows yanking done stories back to current) and
bug 501 (timers don't cancel on stop/completion) compounded the cost.
What this commit lands:
- server/src/crdt_sync.rs (new, ~518 lines): GET /crdt-sync WebSocket
handler that subscribes to locally-applied SignedOps and streams them as
binary frames. Per-peer bounded queue (256 ops) drops slow peers.
- server/src/crdt_state.rs: new public functions subscribe_ops(),
all_ops_json(), apply_remote_op() backing the sync handler. Adds the
CRDT_OP_TX broadcast channel (capacity 1024).
- server/src/main.rs: wires up the sync subsystem at startup.
- server/src/http/mod.rs: registers the new endpoint.
- server/src/config.rs: adds optional rendezvous field for outbound peers.
- server/src/worktree.rs: minor changes from the original branch.
- server/Cargo.toml: cfg lint suppression for CrdtNode derive.
- crates/bft-json-crdt/src/debug.rs: fix unused-variable warnings.
Resolved a trivial test-mod merge conflict in crdt_state.rs (both 478 and
503 added new tests at the end of the test module — kept both sets).
Note: this is the squash of the original 478 work that the user explicitly
authorized landing. The earlier rogue commit ac9f3ecf — which added a
DIFFERENT, broken implementation of the same feature directly to master
under the user's identity without consent — was reverted earlier in this
session. The forensic tags rogue-commit-2026-04-09-ac9f3ecf and
pre-502-reset-2026-04-09 still exist for incident audit.

start_agent unconditionally called move_story_to_current at the top of
its body, before the agent-stage check. When called for mergemaster (or
qa) on a story in 4_merge/ AND a stale 1_backlog/ shadow of the story
existed (post-491/492 split-brain artifact), the move would find the
shadow and yank it to 2_current/, find_active_story_stage would then
report 2_current/, the stage check would expect a Coder agent, and
mergemaster would be rejected — leaving the story in 2_current/ to be
re-promoted by the next auto-assign tick. Infinite loop.
Gate the move so it only fires for Coder-stage agents. QA and
Mergemaster now attach to the story at its existing stage.
Adds a regression test that reproduces the split-brain scenario by
seeding both 4_merge/ and 1_backlog/ copies of the same story and
asserting (1) the stage check does not reject mergemaster, and (2) the
4_merge/ copy is preserved (i.e. not demoted to 2_current/).

leaving a cloned PTY master fd open after the agent exited. When the
pipeline restarted the agent on the same worktree, the stale fd from
the previous session interfered with the new PTY allocation, causing
Claude Code's bundled ripgrep to crash with:
fatal runtime error: assertion failed: output.write(&bytes).is_ok()

The acceptance gate was hardcoded to run cargo clippy, which fails on
non-Rust projects (Go, Node, etc.). Now the gate only runs script/test
which is project-specific. Clippy is added to storkit's own script/test
so Rust linting is preserved for this project.

The LLM was having the conversation with the user but never following
through with wizard_generate calls. The instructions now spell out
the full workflow: get hint, write content, stage it, show user, confirm.
Also adds "keep moving" instruction so the LLM auto-advances to the
next step after confirmation.

Previously unblock only checked for blocked=true. Stories stuck in
merge with a merge_failure field were not considered "blocked" and
unblock refused to act. Now it clears both blocked and merge_failure,
and reports which fields were cleared.

There were two places checking for code changes: the post-cherry-pick
verification (already fixed) and a pre-cherry-pick check in the
merge-queue worktree. The pre-cherry-pick check was still filtering
all of .storkit/ which rejected stories that only change project.toml.

wizard_generate now checks if the project has no source code. On bare
projects, the generation hints tell the LLM to ask the user what they
want to build and what tech stack they plan to use, rather than trying
to read a nonexistent codebase.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The format_wizard_state hints now tell the LLM what to do ("show it
to the user and ask if they're happy") rather than exposing tool names
to the user ("Run wizard_generate").
README wizard instructions now distinguish between existing-code projects
(read codebase, generate files) and bare projects (interview the user
about what they want to build).

The wizard check was only in CLAUDE.md which is Claude-specific.
Move the primary instruction to .storkit/README.md (step 1 of First

Manual merge of story 399 feature branch, adapted for the current CLI
parser (which includes the init subcommand from 429).
- storkit --port 3000 sets the listening port
- storkit --port=3000 also works
- Port resolution: CLI flag > STORKIT_PORT env > default 3001
- Supports combining with init: storkit init --port 3000 /path
- Replaces CliDirective enum with CliArgs struct that handles both
--port and init in a single pass

After the cherry-pick step in run_squash_merge, verify:
1. project_root is on the base branch (not a merge-queue branch)
2. HEAD commit has actual code changes (not an empty/story-only diff)
If either check fails, return success=false so the story stays in merge
stage for retry instead of being phantom-advanced to done.
Also rename move_story_to_archived → move_story_to_done.

Story 424's merge used the wrong variant name HardBlock instead of
RateLimitHardBlock, breaking master compilation.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The initial commit added the `throttled` field to `StoryAgent` but missed
several construction sites in lifecycle.rs, test_helpers.rs, and scan.rs.
Also adds the `HardBlock` match arm in the WebSocket event conversion and
minor CSS/import ordering fixes.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add HardBlock variant to WatcherEvent (story_id, agent_name, reset_time)
- In pty.rs, distinguish allowed_warning (throttle) from hard blocks;
emit RateLimitWarning for throttles, HardBlock for actual 429s
- Add `throttled: bool` field to StoryAgent / AgentInfo
- Pool spawns a background listener that sets throttled=true on
RateLimitWarning or HardBlock events and fires AgentStateChanged
- Status command shows traffic-light dots: ○ idle, ● running, ◑ throttled, ✗ blocked
- Read blocked flag from story front matter for the ✗ dot
- Notifications: RateLimitWarning silenced (too noisy); HardBlock sends
urgent chat notification with optional reset time
- Tests added for traffic_light_dot, read_story_blocked, status output,
and all notification paths
The new WatcherEvent::RateLimitHardBlock variant added in the feature
commit was not covered in the ws.rs From<WatcherEvent> match, causing
a compile error. Add the missing arm returning None (same as
RateLimitWarning — handled by chat notifications only, not WebSocket).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add `unblock` bot command (chat + web UI slash command) that clears the
`blocked` flag and resets `retry_count` to 0 in story front matter
- Works across all pipeline stages (1_backlog through 6_archived)
- Returns confirmation with story name and ID, or clear error if story
is not found or not blocked
- Expose `unblock_story` MCP tool for programmatic use by agents
- Make `chat::commands::unblock` module pub(crate) so story_tools can
call `unblock_by_number`
- Add 8 unit tests covering registration, validation, core logic, and
edge cases (not-found, not-blocked, any stage, story ID in response)
- Update MCP tools list test: 49 → 50 tools
Add three HTTP endpoints for OAuth login without terminal access:
- GET /oauth/authorize — generates PKCE params, redirects to
claude.com/cai/oauth/authorize with code=true and full scopes
- GET /callback — exchanges auth code for tokens via JSON POST to
platform.claude.com/v1/oauth/token, writes ~/.claude/.credentials.json
- GET /oauth/status — returns current credential state as JSON
Uses SHA-256 (sha2 crate) for PKCE code challenge. The authorize URL
targets claude.com/cai/ (not platform.claude.com) which is required
for Max/Pro subscriptions to grant user:inference scope.
Users visit http://localhost:3001/oauth/authorize in their browser
to authenticate. Matrix/WhatsApp can send this link when auth fails.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Detect authentication_failed errors from the Claude Code PTY stream
and automatically refresh the OAuth access token using the stored
refresh token in ~/.claude/.credentials.json.
- New module server/src/llm/oauth.rs: reads credentials, calls
platform.claude.com/v1/oauth/token with JSON body, writes back
- PTY provider detects "error":"authentication_failed" via AtomicBool
- chat_stream retries once after successful refresh
- Clear error message if refresh also fails
On success the retry is transparent. On failure the user sees:
"OAuth session expired. Please run claude login to re-authenticate."

Reverts workarounds added by the 361 agent when the hardened Docker
container broke the test suite:
- gates.rs: restore tempfile::tempdir() (was changed to tempdir_in
CARGO_MANIFEST_DIR to avoid noexec /tmp; noexec is now removed)
- pool/mod.rs: restore ps -p <pid> check in process_is_running (was
changed to /proc/<pid> existence check; procps is now installed)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add procps to runtime stage so `ps` is available for process management
- Remove noexec from /tmp and /home/storkit tmpfs mounts so test scripts

The tmpfs at /home/storkit defaulted to root ownership (mode=755),

Claude Code writes to ~/.claude.json, ~/.cache/, and ~/.npm/ which

Use the known cargo build output path instead of current_exe() when
re-execing after a rebuild. In Docker, the running binary lives at
/usr/local/bin/storkit (read-only) while cargo writes the new binary

would just restart the old binary.

Show test coverage from the cached `.coverage_baseline` file, or rerun the full test suite with `$ARGUMENTS`.
## Usage
-`/coverage` — read cached coverage from `.coverage_baseline` (instant)
-`/coverage run` — run `script/test_coverage` and report fresh results
## What it does
**Cached mode (default):** Reads `.coverage_baseline` and displays the stored coverage percentage(s). This is instant and does not run any tests.
**Run mode (`run`):** Executes `script/test_coverage` which runs:
1. Rust tests with `cargo llvm-cov` (reports line coverage %)
2. Frontend tests with `npm run test:coverage` (reports line coverage %)
3. Computes the overall average and compares to the threshold
Reports Rust coverage, Frontend coverage, Overall coverage, and whether the run passed the threshold.
---
If the arguments (`$ARGUMENTS`) equal `run`, execute `bash script/test_coverage` from the project root and show the Coverage Summary section from the output. Otherwise, read `.coverage_baseline` and display the stored coverage value(s).
Docs live in `website/docs/*.html` (static HTML), **not** Markdown files. When a story asks you to document something, edit the relevant `.html` file in `website/docs/`.
## Configuration files
- Agent config: `.huskies/agents.toml` (preferred) or `[[agent]]` blocks in `.huskies/project.toml`
- Project settings: `.huskies/project.toml`
- Bot credentials: `.huskies/bot.toml` (gitignored — never commit)
## Frontend build
The frontend is embedded into the Rust binary via `rust-embed`. Run `npm run build` in `frontend/` before testing frontend changes, or the embedded assets will be stale.
## Quality gates (all enforced by `script/test`)
1.`npm run build` (frontend)
2.`cargo fmt --all --check`
3.`cargo clippy -- -D warnings`
4.`cargo test`
5.`npm test` (frontend Vitest)
Clippy is zero-tolerance: no warnings allowed. Fix every warning before committing.
## File size
Target a maximum of 800 lines per source file as a soft guide. If a file grows beyond 800 lines, decompose it by concern into smaller modules. Split at natural seams: group related types, functions, or handlers together and move each cohesive group to its own file. This keeps files readable and diffs focused.
## Runtime validation
The `validate_agents` function in `server/src/config.rs` rejects unknown runtimes. Supported values: `"claude-code"` and `"gemini"`. Adding a new runtime requires updating that function.
**Target Audience:** LLM agents working as engineers.
**Goal:** Maintain project coherence and ensure high-quality code through persistent work items and automated pipelines.
---
## 0. First Steps (For New Agent Sessions)
1.**Read CLAUDE.md** in the worktree root for project-specific rules.
2.**Check MCP Tools:** Your `.mcp.json` connects you to the huskies server. Use MCP tools for all pipeline operations — never manipulate files directly.
3.**Check your story:** Call `status(story_id)` or `get_story_todos(story_id)` to see what needs doing.
---
## 1. Pipeline Overview
Work items (stories, bugs, spikes, refactors) move through stages managed by a CRDT state machine:
**All state lives in the CRDT.** There are no filesystem pipeline directories to read or write. Use MCP tools to query and manipulate pipeline state.
---
## 2. Your Workflow as a Coder Agent
1.**Read the story** via `status(story_id)` — understand the acceptance criteria.
2.**Implement** the feature/fix in your worktree. Commit as you go using `git_add` and `git_commit` MCP tools.
3.**Run tests** via the `run_tests` MCP tool (starts tests in the background). Poll `get_test_result` to check completion. Never run `cargo test` or `script/test` directly via Bash.
4.**Check off acceptance criteria** as you complete them using `check_criterion(story_id, criterion_index)`.
5.**Commit and exit.** The server runs acceptance gates automatically when your process exits and advances the pipeline based on the results.
**Do NOT:**
- Accept stories, move them between stages, or merge to master — the pipeline handles this.
- Run tests via Bash — use the MCP tools.
- Create summary documents or write terminal output to files.
---
## 3. Work Item Types
- **Story:** New functionality → implement and test
- **Bug:** Broken functionality → fix with minimal surgical change
- **Spike:** Research/uncertainty → investigate, document findings, no production code
- **Refactor:** Code improvement → restructure without changing behaviour
---
## 4. Bug Workflow
When working on bugs:
1. Read the story description first. If it specifies exact files and locations, go directly there.
2. If not specified, investigate with targeted grep.
3. Fix with a surgical, minimal change.
4. Commit early. Don't spend turns on unnecessary verification.
---
## 5. Code Quality
Before exiting, ensure your code compiles and tests pass. Use `run_tests` MCP tool to verify. Fix all errors and warnings — zero tolerance.
Consult `specs/tech/STACK.md` for project-specific quality gates.
---
## 6. Key MCP Tools
| Tool | Purpose |
|------|---------|
| `status` | Get story details, ACs, git state |
| `get_story_todos` | List unchecked acceptance criteria |
| `check_criterion` | Mark an AC as done |
| `run_tests` | Start test suite (blocks until complete) |
| `git_status` | Worktree git status |
| `git_add` | Stage files |
| `git_commit` | Commit staged changes |
| `git_diff` | View changes |
| `git_log` | View commit history |
---
## 7. Project Architecture
Huskies is a single Rust binary with an embedded React frontend. Key things to know:
- **Backend:** `server/src/` — Rust, built with Poem (HTTP framework)
- **Frontend:** `frontend/src/` — React + TypeScript, built with Vite
- **Gateway mode:** `huskies --gateway` is a deployment mode of the same binary, NOT a separate application. The gateway backend code lives in `server/src/gateway.rs`. Gateway frontend components live in `frontend/src/` alongside everything else.
- **Stories that say "UI":** These are primarily frontend (TypeScript/React) work. Check what backend endpoints already exist before adding new ones. Keep Rust changes minimal.
- **Stories that say "gateway":** The gateway is just a mode. Don't restructure `gateway.rs` unless the story specifically asks for backend changes.
---
## 8. Deployment Modes
Huskies has three modes, all from the same binary:
### Standard (single project)
```
huskies [--port 3001] /path/to/project
```
Full server: web UI, MCP endpoint, chat bot, agent pool, pipeline. One project per instance.
### Headless Build Agent
```
huskies --rendezvous ws://host:port/crdt-sync
```
Connects to an existing huskies instance as a worker node. Syncs the CRDT, claims work from the pipeline, runs agents. No web UI, no chat — just a build worker. Use this to add more compute to a project by running extra containers.
### Gateway (multi-project)
```
huskies --gateway [--port 3000] /path/to/config
```
Lightweight proxy that sits in front of multiple project containers. Reads a `projects.toml` that maps project names to container URLs:
```toml
[projects.huskies]
url="http://huskies:3001"
[projects.robot-studio]
url="http://robot-studio:3002"
```
The gateway presents a unified MCP surface to the chat agent. All tool calls are proxied to the active project's container. Gateway-specific tools:
| Tool | Purpose |
|------|---------|
| `switch_project` | Change the active project |
| `gateway_status` | Show active project and list all registered projects |
| `gateway_health` | Health check all containers |
| `init_project` | Scaffold a new `.huskies/` project at a given path — prefer this over asking the user to run `huskies init` on the CLI |
**Initialising a new project via MCP (preferred):** Instead of asking the user to run `huskies init <path>` in a terminal, call `init_project` with the `path` argument. Optionally pass `name` and `url` to register the project in `projects.toml` immediately. After that, start a huskies server at the path and use `switch_project` to make it active before calling `wizard_status`.

If either shows progress, RESUME from there; do not re-explore the codebase from scratch.

Do not accept stories, move them between stages, or merge to master — the server handles that. For bugs, trust the story description and make surgical fixes. For refactors that delete code or change function signatures, delete first and let the compiler error list be your guide to call sites — do not pre-read files trying to predict what will break.

max_turns=40
max_budget_usd=4.00
prompt="""You are the QA agent for story {{story_id}}. Your job is to verify the coder's work satisfies the story's acceptance criteria and produce a structured QA report.
Read CLAUDE.md first, then .huskies/README.md for the dev process, .huskies/specs/00_CONTEXT.md for what this project does, and .huskies/specs/tech/STACK.md for the tech stack and source map.
## Your Workflow
### 0. Read the Story
- Read the story file at `.huskies/work/3_qa/{{story_id}}.md`
- Extract every acceptance criterion (the `- [ ]` checkbox lines)
- Keep this list in mind for Step 3
### 1. Deterministic Gates (Prerequisites)
Run these first — if any fail, reject immediately without proceeding to AC review:
- Call the `run_tests` MCP tool — it blocks until tests finish and returns the full result directly. All gates must pass (0 lint errors/warnings, all tests green, frontend build clean if applicable). All gates must pass (0 lint errors/warnings, all tests green, frontend build clean if applicable).
### 2. Code Change Review
- Run `git diff master...HEAD --stat` to see what files changed
- Run `git diff master...HEAD` to review the actual changes
- Flag any incomplete implementations:
- `todo!()`, `unimplemented!()`, `panic!()` used as stubs
- Placeholder strings like "TODO", "FIXME", "notimplemented"
- Empty match arms or arms that just return `Default::default()`
- Hardcoded values where real logic is expected
- Note any obvious coding mistakes (unused imports, dead code, unhandled errors)
### 3. Acceptance Criteria Review
For each AC extracted in Step 0:
- Review the diff and test files to determine if the code addresses this AC
- PASS: describe specifically how the code addresses it (which file/function/test)
- FAIL: explain exactly what is missing or incorrect
An AC fails if:
- No code change or test relates to it
- The implementation is stubbed out (todo!/unimplemented!)
- A test exists but doesn't actually assert the behaviour described
### 4. Manual Testing Support (only if all gates PASS and all ACs PASS)
- Build: run `run_build` MCP tool and note success/failure
- If build succeeds: find a free port (try 3010-3020), set `HUSKIES_PORT=<port>` and start the server with `script/server`
- Generate a testing plan including:
- URL to visit in the browser
- Things to check in the UI
- curl commands to exercise relevant API endpoints
- Stop the test server when done: send SIGTERM to the `script/server` process (e.g. `kill <pid>`)
### 5. Produce Structured Report and Verdict
Print your QA report to stdout. Then call `approve_qa` or `reject_qa` via the MCP tool based on the overall result. Use this format:
```
## QA Report for {{story_id}}
### Code Quality
- run_tests MCP tool: PASS/FAIL (details)
- Incomplete implementations: (list any todo!/unimplemented!/stubs found, or "None")
- Other code review findings: (list any issues found, or "None")
### Acceptance Criteria Review
- AC: <criterion text>
Result: PASS/FAIL
Evidence: <how the code addresses it, or what is missing>
(repeat for each AC)
### Manual Testing Plan
- Server URL: http://localhost:PORT (or "Skipped—gate/ACfailure" or "Buildfailed")
- Pages to visit: (list, or "N/A")
- Things to check: (list, or "N/A")
- curl commands: (list, or "N/A")
### Overall: PASS/FAIL
Reason: (summary of why it passed or the primary reason it failed)
```
After printing the report:
- If Overall is PASS: call `approve_qa(story_id='{{story_id}}')` via MCP
- If Overall is FAIL: call `reject_qa(story_id='{{story_id}}', notes='<concise reason>')` via MCP so the coder knows exactly what to fix
## Rules
- Do NOT modify any code — read-only review only
- Gates must pass before AC review — a gate failure is an automatic reject
- If any AC is not met, the overall result is FAIL
- Always call approve_qa or reject_qa — never leave the story without a verdict"""

## Your Workflow
1. Call merge_agent_work(story_id='{{story_id}}'). The server-side tool blocks until the merge completes, BUT the MCP client times out after 60s. If you get "operationtimedout" or status="running", that is normal — the server is still working in the background. Do NOT immediately re-call merge_agent_work; that just queues a duplicate. Instead, follow Step 2.
2. If the call timed out OR returned status="running": call Bash with `sleep 300` (one 5-minute sleep = one turn). Then call get_merge_status once. Repeat up to 3 times (15 minutes total). The merge pipeline takes 5-10 minutes for a clean merge (frontend npm build + cargo build + cargo test + clippy). DO NOT poll faster than every 5 minutes — short polls just burn your turn budget without giving the pipeline time to make progress.
3. If get_merge_status eventually returns success: you're done. Exit.
4. If gates failed: read the gate_output carefully, fix the issues in the merge workspace at `.huskies/merge_workspace/`, run run_tests MCP tool to verify, recommit, and call merge_agent_work again.
5. If merge failed for any other reason: call report_merge_failure(story_id='{{story_id}}', reason='<details>') and exit.
6. After 3 failed fix attempts, call report_merge_failure and exit.
## Fixing Gate Failures
The auto-resolver often produces broken code. Common problems:
- Duplicate imports or definitions (kept both sides)
- Formatting issues (import ordering, line breaks)
- Unclosed delimiters from bad conflict resolution
- Type mismatches from incompatible merge of both sides
To fix:
1. Read the broken files in `.huskies/merge_workspace/`
2. Fix the issues — prefer master's structure, integrate only the feature's new code
3. Run run_lint MCP tool to check formatting
4. Run run_tests MCP tool to verify everything passes
5. Commit the fix and call merge_agent_work again
## Rules
- NEVER manually move story files between pipeline stages
- NEVER call accept_story — merge_agent_work handles that
- ALWAYS call report_merge_failure if you can't fix the merge"""
system_prompt="You are the mergemaster agent. Call merge_agent_work to merge. If gates fail, fix the issues in the merge workspace, verify with run_lint and run_tests MCP tools, recommit, and retrigger. After 3 failed attempts, call report_merge_failure and exit. Never move story files or call accept_story. CRITICAL: When fixing gate failures, commit the fix on feature/story-{id} (the feature branch), NOT in the merge_workspace — commits made in the merge_workspace are discarded when the next squash-merge re-runs from the feature branch. Example: cd /workspace/.huskies/worktrees/{id} && git add ... && git commit && retrigger merge. When resolving merge conflicts: before editing any conflicted file, use git blame and git log on the merge commit to identify the originating story IDs for each side of the conflict. Read those stories' spec files (.huskies/work/ or .huskies/specs/) to understand the intent of each change. Resolve conflicts in a way that satisfies both stories' intent, and explain the resolution in the merge commit message (cite the story IDs and why you chose the resolution you did)."
Recurring issues observed during pipeline operation. Review periodically and create stories for systemic problems.
## 2026-03-18: Stories graduating to "done" with empty merges (7 of 10)
Pipeline allows stories to move through coding → QA → merge → done without any actual code changes landing on master. The squash-merge produces an empty diff but the pipeline still marks the story as done. Affected stories: 247, 273, 274, 278, 279, 280, 92. Only 266, 271, 277, and 281 actually shipped code. Root cause: no check that the merge commit contains a non-empty diff. Filed bug 283 for the manual_qa gate issue specifically, but the empty-merge-to-done problem is broader and needs its own fix.
## 2026-03-18: Agent committed directly to master instead of worktree
Multiple agents have committed directly to master instead of their worktree/feature branch:
- Commit `5f4591f` ("fix: update should_commit_stage test to match 5_done") — likely mergemaster
- Commit `a32cfbd` ("Add bot-level command registry with help command") — story 285 coder committed code + Cargo.lock directly to master
Agents should only commit to their feature branch or merge-queue branch, never to master directly. Suspect agents are running `git commit` in the project root instead of the worktree directory. This can also revert uncommitted fixes on master (e.g. project.toml pkill fix was overwritten). Frequency: at least 2 confirmed cases. This is a recurring and serious problem — needs a guard in the server or agent prompts.
## 2026-03-19: Auto-assign re-assigns mergemaster to failed merge stories in a loop
After bug 295 fix (`auto_assign_available_work` after every pipeline advance), mergemaster gets re-assigned to stories that already have a merge failure flag. Story 310 had an empty diff merge failure — mergemaster correctly reported the failure, but auto-assign immediately re-assigned mergemaster to the same story, creating an infinite retry loop. The auto-assign logic needs to check for the `merge_failure` front matter flag before re-assigning agents to stories in `4_merge/`.
## 2026-03-19: Coder produces no code (complete ghost — story 310)
Story 310 (Bot delete command) went through the full pipeline — coder session ran, passed QA/gates, moved to merge — but the coder produced zero code. No commits on the feature branch, no commits on master. The entire agent session was a no-op. This is different from the "committed to master instead of worktree" problem — in this case, the coder simply did nothing. Need to investigate the coder logs to understand what happened. The empty-diff merge check would catch this at merge time, but ideally the server should detect "coder finished with no commits on feature branch" at the gate-check stage and fail early.
## 2026-03-19: Auto-assign assigns mergemaster to coding-stage stories
Auto-assign picked mergemaster for story 310 which was in `2_current/`. Mergemaster should only work on stories in `4_merge/`. The `auto_assign_available_work` function doesn't enforce that the agent's configured stage matches the pipeline stage of the story it's being assigned to. Story 279 (auto-assign respects agent stage from front matter) was supposed to fix this, but the check may only apply to front-matter preferences, not the fallback assignment path.

| `POST /api/anthropic/key` | Encrypted file/env | Stay out of CRDT (secrets) | |
| `PUT /api/bot/config` | `.huskies/bot.toml` file | Stay out of CRDT (credentials) | |
| `POST /mcp` | CRDT (already) | Already replicated via CRDT WebSocket bus | Story/pipeline mutations are CRDT-native |
| Merge job tracking | `AgentPool.merge_jobs: HashMap<String, MergeJob>` | `merge_jobs` — LWW map by story_id, or append-only log | Needed for cross-node merge visibility |
| Test job tracking | `AppContext.test_job_registry: HashMap<WorkPath, TestJob>` | `test_jobs` — LWW map by story_id | Needed so any node can query test status |
Write mutations already flow through the CRDT bus (signed ops). Read endpoints are the remaining HTTP surface that could be migrated to the same WebSocket channel. This section drafts the envelope format so read RPCs can share the bus without requiring Ed25519 auth (unsigned reads are fine; only writes need authenticity guarantees).
Each request carries a UUID v4 `correlation_id`. The responder echoes it verbatim. Callers maintain a `HashMap<String, oneshot::Sender>` to route responses back to waiting futures. On TTL expiry the entry is removed and the caller receives `Err(Timeout)`.
### TTL Semantics
- Caller specifies `ttl_ms` (default 5000, max 30000).
- If the responding peer does not answer within the TTL, the caller synthesises a `TIMEOUT` error response locally.
- Responders do not need to track TTLs; they answer as fast as they can.
- Callers may use stale cached results if `ttl_ms == 0` is supplied and a cache entry exists (opt-in freshness trade-off).
### Error Codes
| Code | Meaning |
|------|---------|
| `NOT_FOUND` | Resource does not exist |
| `TIMEOUT` | Peer did not respond within TTL |
| `PEER_OFFLINE` | No live peer with the requested capability is connected |
| `gateway.rs::GatewayState` | `pending_tokens` | `HashMap<String, PendingToken>` | **LWW-map** keyed by token UUID, with `expires_at` TTL field | Tokens are short-lived; LWW is fine; GC by TTL |
| `agents/pool/mod.rs::AgentPool` | `agents` (running agent handles) | `HashMap<String, StoryAgent>` | **LWW-map**`active_agents` keyed by story_id; fields: node_id, agent_name, pid(optional), started_at, status | Process handles stay local; only metadata replicated |
| `http/context.rs::AppContext` | `test_job_registry` | `HashMap<WorkPath, TestJob>` (TestJobRegistry) | **LWW-map**`test_jobs` keyed by story_id; fields: node_id, status, started_at, finished_at | Needed so any node can query test run status |
| `agents/pool/auto_assign` | agent throttle / last-seen timestamps | Local variables / in-memory | **LWW-map**`agent_throttle` keyed by agent_name; field: last_dispatched_at | Prevents double-dispatch on multi-node |
| `gateway.rs::GatewayState` | `active_project` | `Arc<RwLock<String>>` | **LWW register** in `gateway_config` collection, field `active_project` | Single-value; LWW is correct |
| `gateway.rs::GatewayState` | `projects` (BTreeMap) | `Arc<RwLock<BTreeMap<String, ProjectEntry>>>` | **LWW-map** in `gateway_config.projects` keyed by project name | Infrequently mutated; LWW correct |
### Summary of Proposed New CRDT Collections
| Collection | Type | Notes |
|-----------|------|-------|
| `tokens` | LWW-map | Join tokens with TTL; garbage-collect on expiry |
**Story 665 (Ed25519 auth)** must land before any write operation is migrated to the CRDT bus. Unsigned writes on a shared bus would allow any connected peer to forge mutations. Read RPCs do not require auth.
### Wave 0 — Foundation (no story 665 needed)
These can land in parallel with or before story 665:
1.**Extend `nodes` CRDT collection** with `label`, `address`, `assigned_project`, `last_seen_ms` fields. This is a pure schema addition.
2.**Add `merge_jobs` and `active_agents` LWW-maps** to the CRDT document schema (additive; existing nodes ignore unknown fields via `serde(default)`).
3.**Implement unsigned read-RPC multiplexer** on the existing `/crdt-sync` WebSocket channel (new `kind: "rpc_request"/"rpc_response"` frame types, ignored by old peers).
[huskies] Container stopped. Starting new container…
[huskies] Health check passed ✅ (2 s)
```
On failure:
```
[huskies] Health check failed after 30 s ❌
[huskies] Rolling back to previous image (sha256:def456)…
[huskies] Rollback complete ✅
```
### Error cases
| Condition | Response |
|-----------|----------|
| Unknown project name | `Unknown project 'foo'. Known projects: huskies, robot-studio` |
| No Docker socket access | `Update not available: Docker socket not mounted` |
| Rollback with no previous image | `No previous image recorded for 'huskies'; cannot roll back` |
| Project container not managed by Docker | `'huskies' is not a container-managed project; rebuild it manually` |
---
## 3. Auth
### 3.1 Threat model
The update command triggers container replacement — a privileged operation equivalent to `docker compose up -d`.
An unauthenticated attacker who can send a message to the bot room could force a rolling restart or roll back a working container.
### 3.2 Proposed approach: room + role guard
**Layer 1 — Room restriction.**
The update command is only accepted in a designated *ops room*, configured in `bot.toml` (or `projects.toml`):
```toml
[gateway.ops_room]
room_id="!abc123:homeserver.example.com"
```
Messages from other rooms are rejected with: `The update command is only available in the ops room.`
**Layer 2 — Sender role check (Matrix/Slack).**
The bot checks the sender's power level (Matrix) or admin status (Slack/Discord).
Only users with power level ≥ 50 (moderator) on Matrix, or workspace admin on Slack, may issue `update`.
Unapproved senders receive: `You do not have permission to issue update commands.`
**Layer 3 — Confirmation prompt for destructive operations.**
`update all` affects every project.
The bot responds with a confirmation challenge:
```
This will restart all 3 project containers. Reply `yes` within 60 s to confirm, or `no` to cancel.
```
Single-project updates (`update huskies`) do **not** require confirmation — they are already scoped.
### 3.3 Future: Ed25519 operator token
When story 665 (Ed25519 auth) lands, the gateway's node identity keypair can sign an operator token.
The bot verifies the token against the node's public key before acting.
This removes the room/role dependency and allows the command to be issued programmatically
(e.g. from a CI pipeline via MCP).
For now the room + role guard is sufficient.
---
## 4. Rollout Approach
### 4.1 Docker-managed containers (primary path)
The gateway process has access to the Docker socket (mounted as a volume at `/var/run/docker.sock`).
The update sequence for a single project:
1.**Record current image** — read the running container's image digest (store in gateway's `update_history` LWW-map in CRDT, keyed by project name).
2.**Pull new image** — `docker pull <image>` (or the compose-file equivalent tag).
3.**Drain connections** — gateway marks the project as `updating`; new proxy requests return 503 with a `Retry-After: 5` header; in-flight requests are allowed to complete (30 s grace window).
4.**Stop old container** — `docker stop --time=30 <container_name>`.
5.**Start new container** — `docker start <container_name>` (or `docker compose up -d <service>`).
6.**Health check** — poll the project's `/health` endpoint until 200 OK or 30 s timeout.
7.**Restore routing** — remove the `updating` flag; proxy resumes normal operation.
Steps 1–7 are serialised per project. When `update all` is used, projects are updated **one at a time** (not in parallel) to limit blast radius.
### 4.2 Source-rebuild path (non-Docker / dev mode)
When Docker is not available (the gateway binary is running directly on the host, not in a container),
the update command falls back to the existing `rebuild_and_restart` flow (`server/src/rebuild.rs`):
`cargo build` → re-exec.
This path cannot update individual projects independently — it rebuilds the gateway itself.
### 4.3 Gateway state during update
```
normal → updating → (success) normal
→ (failure) rolling_back → normal
```
The CRDT `gateway_config` collection gains two new LWW fields per project:
The frontend can use this to show/hide an "Update" button in the gateway project list.
### 6.4 Async dispatch
`update` is an async command (like `rebuild`, `htop`, `start`).
The command keyword is detected in `on_room_message` before `try_handle_command` is invoked.
The handler spawns a `tokio::spawn` task, posts incremental updates via the existing transport's `send_message` / `edit_message` API, and returns.
---
## 7. Open Questions
| # | Question | Notes |
|---|----------|-------|
| 1 | Should the Docker socket be mounted in the gateway container by default? | Security trade-off: socket access = container escape risk. Alternative: `docker exec` via a sidecar. |
| 2 | Should `update all` use a sequential or rolling strategy? | Sequential is safer; rolling is faster. Sequential chosen for v1. |
| 3 | How do we handle projects not managed by Docker (e.g. running on bare metal)? | Fallback to `rebuild` covers the gateway itself; project-specific fallback is out of scope for v1. |
| 4 | Should the confirmation challenge expire? | Yes — 60 s timeout, configurable in `bot.toml`. |
| 5 | Should update history be persisted beyond CRDT (i.e. across full gateway restarts)? | CRDT persists to SQLite, so yes, as long as the CRDT DB survives the restart. |
| 6 | Multi-gateway HA: which node triggers the actual Docker call? | The node that owns the Docker socket. CRDT `update_state` prevents double-triggering. |
---
## 8. Dependencies
| Story / Spike | Dependency type |
|--------------|----------------|
| Spike 679 (HTTP → CRDT bus) | Soft — `gateway_config` LWW collection needed for update state; can stub without it |
| Story 665 (Ed25519 auth) | Soft — operator token auth is a future hardening step; room+role guard suffices for v1 |
| `server/src/rebuild.rs` | Direct — reuse `rebuild_and_restart` for the non-Docker path |
| `server/src/gateway_relay.rs` | Indirect — update state changes should trigger relay events to connected frontends |
- **State:** BFT CRDT replicated document backed by SQLite
- **Agents:** Claude Code CLI spawned in PTY pseudo-terminals
- **Package manager:** cargo
## Frontend
- **Language:** TypeScript + React

- **Migrate HTTP route → CRDT:** delete from `gateway.rs` / `http/*`, add op to `service/<area>/`, write through `crdt_state/`
- **New front-matter field:** add to `StoryMetadata` and `FrontMatter` in `io/story_metadata.rs` plus a `write_<name>_in_content` helper
# Story 388: WhatsApp webhook HMAC signature verification
## User Story
As a bot operator, I want incoming WhatsApp webhook requests to be cryptographically verified, so that forged requests from unauthorized sources are rejected.
## Acceptance Criteria
- [ ] Meta webhooks: validate X-Hub-Signature-256 HMAC-SHA256 header using the app secret before processing
- [ ] Twilio webhooks: validate request signature using the auth token before processing
- [ ] Requests with missing or invalid signatures are rejected with 403 Forbidden
- [ ] Verification is fail-closed: if signature checking is configured, unsigned requests are rejected
- [ ] Existing bot.toml config is extended with any needed secrets (e.g. Meta app_secret for HMAC verification)
- [ ] MUST use audited crypto crates (hmac, sha2, sha1, base64) — no hand-rolled cryptographic primitives

# Spike 408: Fly.io Machines API integration for multi-tenant huskies SaaS
## Question
Can we build a working Rust integration that creates and manages per-tenant Fly.io Machines, attaches volumes, injects Claude credentials, and proxies JWT-authenticated HTTP/WebSocket traffic to the right machine?
## Hypothesis
A thin Rust service using `reqwest` for the Machines API and `axum` for the reverse proxy is sufficient. No heavyweight orchestration framework needed.
## Prerequisites
- Fly.io account with API token (set `FLY_API_TOKEN` env var)
- Spike 407 findings reviewed
## Timebox
4 hours
## Investigation Plan
- [ ] Create a minimal Rust crate in `spikes/fly_machines/` — do not touch production code
- [ ] Implement machine lifecycle: create, start, stop, destroy via Fly Machines REST API using `reqwest`
- [ ] Test attaching a persistent volume to a machine and verify it persists across stop/start
- [ ] Test secret injection — pass a dummy `credentials.json` as a Fly secret and verify it's readable inside the machine
- [ ] Sketch the auth proxy: JWT validation → machine lookup → reverse proxy to machine's private IP; verify WebSocket proxying works
- [ ] Measure actual cold start time for a minimal huskies container image
- [ ] Document any API quirks, rate limits, or sharp edges discovered during testing

# Story 411: Multi-account OAuth token rotation on rate limit
## User Story
As a huskies user with multiple Claude Max subscriptions, I want the system to automatically rotate to a different account when one gets rate limited, so that agents and chat don't stall out waiting for limits to reset.
## Acceptance Criteria
- [ ] OAuth login flow stores credentials per-account (keyed by email), not overwriting previous accounts
- [ ] GET /oauth/status returns all stored accounts and their status (active, rate-limited, expired)
- [ ] When the active account hits a rate limit, huskies automatically swaps to the next available account's refresh token, refreshes, and retries
- [ ] The bot sends a notification in Matrix/WhatsApp when it swaps accounts
- [ ] If all accounts are rate limited, the bot surfaces a clear message with the time until the earliest reset
- [ ] A new /oauth/authorize login adds to the account pool rather than replacing the current credentials

# Story 412: Recheck bot command to re-run gates without restarting agent
## User Story
As a user, I want to send `recheck <number>` to the bot so that it re-runs acceptance gates on an existing worktree without spawning a new agent, so I can unblock stories that failed due to environment issues without wasting agent turns.
## Acceptance Criteria
- [ ] recheck command is registered in chat/commands/mod.rs and appears in help output
- [ ]`recheck <number>` runs run_acceptance_gates on the story's existing worktree
- [ ] If gates pass, the story advances through the pipeline (same as if a coder completed successfully)
- [ ] If gates fail, the error output is returned to the user (not silently retried)
- [ ] If no worktree exists for the story, returns a clear error
- [ ] Does not spawn a new agent or increment retry_count
- [ ] Works from all transports (Matrix, WhatsApp, Slack)

# Story 435: Unblock command handles all stuck states not just blocked flag
## User Story
As a project owner, I want the unblock command to clear any stuck state on a story — not just the blocked flag — so that I have a single command to unstick stories regardless of why they're stuck.
## Acceptance Criteria
- [ ] Unblock clears merge_failure field in addition to blocked flag
- [ ] Unblock clears review_hold field
- [ ] Unblock reports which fields were cleared in the confirmation message
- [ ] Unblock works on stories in any pipeline stage (backlog, current, qa, merge, done)
- [ ] If no stuck state is found (no blocked, merge_failure, or review_hold), returns a clear message saying so
name: "Unify story stuck states into a single status field"
status: "superseded"
superseded_by: 520
---
# Refactor 436: Unify story stuck states into a single status field
## Current State
- TBD
## Desired State
Replace the separate blocked, merge_failure, and review_hold front matter fields with a single status field (e.g. status: blocked, status: merge_failure, status: review_hold). Simplifies the unblock command, auto-assign checks, and pipeline advance logic.
## Acceptance Criteria
- [ ] Replace blocked: true, merge_failure: string, and review_hold: true with a single status: field in story front matter
- [ ] Auto-assign checks a single field instead of three separate ones
- [ ] Pipeline advance and lifecycle code reads/writes the unified status field
- [ ] Unblock command clears the status field regardless of which stuck state it was
- [ ] retry_count remains a separate field (it's a counter, not a state)

# Story 479: Build agent mode with CRDT-based work claiming
## User Story
As a user with multiple laptops, I want to run huskies in build agent mode so it connects to the mesh, syncs state, and autonomously picks up and runs coding work.
## Acceptance Criteria
- [ ] New CLI mode: huskies agent --rendezvous ws://host:3001
- [ ] Agent mode: syncs CRDT state, runs coders, no web UI or chat interface
- [ ] Work claiming via CRDT: node writes claim (node ID) to CRDT doc, merge resolves conflicts deterministically, losing node stops work
- [ ] Agent picks up stories in current stage and runs Claude Code locally
- [ ] Agent pushes feature branch to Gitea when done, reports completion via CRDT
- [ ] Handles offline/reconnect: CRDT merges on reconnect, interrupted work is reclaimed after timeout

# Bug 486: create_worktree deletes all files from main branch git index
## Description
On the reclaimer project, the create_worktree operation for story 34 produced a commit (cea0c48) with message "huskies: create 34_story_drawer_open_pushes_main_view_aside_with_animation" that removed 76 files (9853 deletions) from the main branch git index. All files remained on disk — nothing was lost — but every tracked file became untracked. Static analysis of the watcher code (watcher.rs:152-185) shows git add -A .huskies/work/ with correct current_dir, which should only affect files under .huskies/work/. No other code path in the server runs git add without a pathspec on the main branch. Root cause is unknown — may be related to the storkit→huskies migration leaving the git index in an inconsistent state, or a race condition during first-time scaffold on a project that previously used .storkit/.
## How to Reproduce
1. Uncertain — may require fresh huskies setup on a project that previously used storkit. 2. Create a story via the bot or MCP tool. 3. Observe that the auto-commit for story creation removes all tracked files from the git index.
## Actual Result
The commit for story creation deleted 76 files (9853 deletions) from the git index while leaving them on disk.
## Expected Result
The commit for story creation should only add the new story markdown file under .huskies/work/1_backlog/. No other files should be affected.

# Bug 498: Stale merge job lock prevents new merges after agent dies
## Description
When the mergemaster agent is killed or stops while a merge is in progress, the in-memory `merge_jobs` map retains a `Running` status entry for that story. Subsequent attempts to call `merge_agent_work` get "Merge already in progress" and fail. The lock is never cleaned up.
This causes the mergemaster to loop: spawn, try merge, get "already in progress", waste turns, exit, respawn. The merge never completes.
The fix: clear the merge job entry when the mergemaster agent exits (whether cleanly or via kill/stop).
## How to Reproduce
1. Start mergemaster on a story in merge
2. Kill/stop the mergemaster agent before merge completes
3. Try to merge_agent_work again for the same story
4. Get "Merge already in progress" error
## Actual Result
Stale Running entry in merge_jobs map blocks all future merge attempts until server restart.
## Expected Result
Merge job lock is cleaned up when the agent exits, allowing retry.

# Bug 511: CRDT lamport clock (inner.seq) resets to 1 on server restart instead of resuming from max(own_author_seq) + 1
## Description
When the huskies server restarts (e.g. via `rebuild_and_restart`), the local node's CRDT lamport clock — `inner.seq` on each `SignedOp` — appears to reset to 1 instead of resuming from `MAX(seq) + 1` for the local author's own previously-persisted ops.
**Discovered live on 2026-04-09** while inspecting the `crdt_ops` table after a `rebuild_and_restart`. Pre-restart ops were at seqs 485-492 (creation ops for stories 503-510). Post-restart ops were being persisted at seqs 1, 2, 3, 4, 5, 6, 7 — visible by sorting `crdt_ops` by `created_at DESC`:
```
created_at | seq
2026-04-09T18:49:56 → seq 7 ← post-restart
2026-04-09T18:38:22 → seq 6 ← post-restart
2026-04-09T18:37:45 → seq 492 ← pre-restart, last write before restart
2026-04-09T18:31:32 → seq 4 ← post-restart
2026-04-09T18:27:04 → seq 3 ← post-restart
```
So the local node, which had reached seq=492 before the restart, started writing new ops at seq=1 after the restart and is now climbing from there. This means **new ops have lower seqs than existing ops from the same author**.
## Why this matters
In a BFT JSON CRDT, `inner.seq` is the local lamport clock used for causality tracking. The library assumes per-author seqs are monotonically increasing — newer ops from the same author have higher seqs than older ops. Several things break when this invariant is violated:
1.**Causality / ordering on remote replay.** When a peer (or this same node after another restart) replays the persisted ops in `seq` order, the post-restart ops will be applied *before* the pre-restart ops, even though they happened later. This can produce a non-deterministic state and can cause field updates to "go backwards" — e.g. a story that was moved current → done pre-restart, then nothing post-restart, would correctly end at "done"; but if you also did a post-restart action, the seq ordering would re-play it in the wrong order.
2.**Op ID collisions.** The op id is a hash of the op contents (including author, seq, content). If a post-restart op happens to be structurally identical to a pre-restart op (e.g. "set stage to 1_backlog" with the same author and same seq=3), the op ids could collide. The persistence path uses `INSERT INTO crdt_ops ... ON CONFLICT(op_id) DO NOTHING`, which would *silently drop* the new op. (We have not yet observed this happen, but it's a latent risk.)
3.**Sync between nodes will desync.** Once the WebSocket sync layer (story 478, just merged) is exchanging ops between nodes, a restart on one node will produce ops with seqs that look "old" to the other node, and the receiving node may de-dupe or mis-order them. This will manifest as silent state divergence in multi-node deployments, which is exactly what the sync layer is supposed to prevent.
4.**Today's pipeline state confusion.** The 8 stories I created in this session (503-510) are at seqs 485-492 in the persisted CRDT. Their post-restart lifecycle moves are at seqs 1-15. If we replay the CRDT from disk in seq order, the lifecycle moves will be applied to *empty* state before the creation ops have run, and will silently no-op (because they reference content indexes that don't exist yet). On the next restart after this state, the in-memory view will show the stories in their *creation* state, not their post-restart-lifecycle state — i.e. all 8 stories will appear "stuck at 1_backlog" again. **This may well be the cause of bug 510's split-brain symptom**.
## Where the bug lives
`server/src/crdt_state.rs::init()` (around lines 80-115) replays persisted ops to reconstruct state, then constructs a fresh `CrdtState { crdt, keypair, index, persist_tx }`. The `BaseCrdt::new(&keypair)` call constructs a fresh CRDT with a fresh internal seq counter. The replay re-applies ops via `crdt.apply(signed_op)` which presumably updates the doc but does NOT advance the local seq counter (because `apply()` is for *remote* ops).
After replay, the local seq counter is at 0 (or wherever the BFT CRDT library defaults). The next call to `apply_and_persist` produces an op with `inner.seq = 1` (or whatever the next-counter value is) — even though there are already ops at seq 485+ from this author in the persisted state.
The fix is to inspect `MAX(inner.seq)` for ops where `author == local_keypair.public()` after the replay, and seed the BFT CRDT's local seq counter from `max + 1`. The exact API for "seed the seq counter" depends on the bft-json-crdt library — may need a small upstream change if not already exposed.
## How to Reproduce
1. Start a fresh huskies server with an empty database. Verify `crdt_ops` is empty.
2. Create several stories via `create_story` or similar — observe ops being persisted at incrementing seqs (1, 2, 3, ...).
3. Note the highest seq via `sqlite3 .huskies/pipeline.db "SELECT MAX(seq) FROM crdt_ops;"` — call this N.
4. Stop the server and start it again (or `rebuild_and_restart`).
5. Create another story via `create_story`.
6. Query `SELECT seq, created_at FROM crdt_ops ORDER BY created_at DESC LIMIT 5;`
## Actual Result
The new op (just created in step 5) is persisted with `seq = 1` (or some small value), NOT `seq = N + 1`. The lamport clock has been reset.
Concretely on 2026-04-09 we observed seqs in `crdt_ops` ordered by `created_at` DESC of: 7, 6, 492, 4, 3 — i.e. post-restart writes were at seqs 3, 4, 6, 7 even though the highest pre-restart seq was 492.
## Expected Result
After restart, the local node's seq counter must resume from `MAX(inner.seq)` across all persisted ops where `author == local_keypair.public()`, plus 1. The next op written by the local node should have `seq = N + 1` where N is the previous local high-water mark.
Equivalent stated: `inner.seq` on the local author's ops must be monotonically increasing across the entire lifetime of the local node's keypair, not just within a single process invocation.
## Acceptance Criteria
- [ ] After a server restart, the next CRDT op written by the local node has seq = MAX(local_author_seq from crdt_ops) + 1, not 1
- [ ] Regression test: seed crdt_ops with an op at seq=100 by the local author, restart the CRDT subsystem (or call init() in a test harness), trigger a write_item, assert the new op has seq=101
- [ ] Regression test: a brand-new node (no pre-existing ops) still starts at seq=1 (no off-by-one introduced by the fix)
- [ ] Inter-node test: simulate two nodes A and B, A writes ops up to seq=50, A restarts, A writes a new op which should be seq=51, broadcast to B, assert B applies it in the correct causal position
- [ ] If the fix requires changes to bft-json-crdt itself (to expose a way to seed the local seq), the upstream change is documented in the bug body and either landed or vendored
- [ ] After this fix is in place, replay-on-restart for the existing data (8 stories in pipeline_items at seqs 485-492 with lifecycle moves at seqs 1-15) is verified to produce the correct in-memory state — OR the existing broken-seq data is migrated as part of the fix

# Story 512: Migrate chat commands from filesystem lookup to CRDT/DB
## User Story
**Depends on story 520** (typed pipeline state machine). This story is best implemented as a *consumer* of the typed transition API, not against the loose `PipelineItemView`. Wait for 520 to land first, then migrate the chat command lookups to use the typed `find_story_by_number → Result<PipelineItem, _>` helper from the new module.
---
**Note:** content stuffed into user_story per bug 509 workaround.
## Context
All the slash-style chat commands in `server/src/chat/commands/{move_story,show,depends,unblock}.rs` and `server/src/chat/transport/matrix/{start,assign,delete}.rs` look up stories by **searching for `.huskies/work/*/N_*.md` filesystem files**. After the 491/492 migration moved story content out of the filesystem and into `pipeline_items` + CRDT, these commands silently fail with `"No story, bug, or spike with number {N} found"` for any story whose filesystem shadow doesn't exist — *even when the story is fully present in the DB and CRDT*.
## Real user story
As a user typing chat commands in the web UI or the matrix bot, I want move/show/depends/unblock/start/assign/delete to find any story that's in the pipeline regardless of whether its filesystem shadow exists, so the chat workflow stays usable post-migration.
## Observed 2026-04-09
Master commit `41515e3b` had 503's code, the in-memory CRDT view had 503 at stage='merge', the `pipeline_items` row existed (post my-sqlite-update at `5_done`), but `move 503 done` in the web UI returned **`No story, bug, or spike with number 503 found`** because no `.huskies/work/4_merge/503_*.md` file existed.
## Implementation note
The MCP `move_story` tool already does this correctly: it goes through `lifecycle::move_item` which checks `crdt_state::read_item(story_id)` first. The chat commands need to use the same lookup helper. The fix should consolidate all "find story by number" logic into one shared function used by every command.

## Acceptance Criteria
- [ ] All seven chat commands (move_story, show, depends, unblock, start, assign, delete) successfully find stories that exist in CRDT but have no filesystem shadow
- [ ] Backward compat: commands still work for stories with only filesystem shadows (during the migration window)
- [ ] A single shared `find_story_by_number` helper is introduced and used by every chat command
- [ ] Lookup priority order is documented and consistent: CRDT first, then pipeline_items, then filesystem fallback
- [ ] Regression test per command covering CRDT-only, filesystem-only, both-present, and not-found cases
- [ ] Observed repro from 2026-04-09 (move 503 done failing even though 503 was fully present in CRDT and pipeline_items) is the canonical regression case

# Story 513: Startup reconcile pass that detects drift between CRDT, pipeline_items, and filesystem shadows
## User Story
**Note:** content stuffed into user_story per bug 509 workaround.
---
## Context
Post-491/492, huskies has **four places state lives** that can drift apart:
1.`crdt_ops` table — the persisted CRDT operation log (intended source of truth)
2. In-memory CRDT view — `state.crdt.doc.items` reconstructed from `crdt_ops` on startup, mutated by `apply_and_persist` during runtime
3.`pipeline_items` table — a shadow / materialised view, written to as a shadow alongside CRDT writes
4. Filesystem shadows in `.huskies/work/N_stage/*.md` — legacy rendering, still written by some paths and read by others
There is currently **no reconcile pass** that detects drift between them. We've watched this drift bite repeatedly today: stories appear in some views and not others, lifecycle moves happen in one but not another, my direct sqlite UPDATE was invisible to the API, etc. Each individual view looks "fine" in isolation, but the drift only becomes visible when a user notices a story behaving inconsistently.
## Real user story
As a developer or operator running huskies, I want a startup reconcile pass that compares all four state sources and either reconciles them automatically (preferred) or logs structured warnings about the drift, so I can detect and diagnose state corruption before it causes user-visible bugs.
## Observed 2026-04-09
Throughout this session we observed: 478 in pipeline_items but missing from CRDT (after a direct sqlite insert), 503 in CRDT at stage=merge but pipeline_items at stage=5_done (after my UPDATE), filesystem shadows in `1_backlog/` for stories that were already in 5_done in the DB (bug 510), etc. None of these were detected by huskies itself — they were all only found by running ad-hoc `SELECT` queries during incident response.
## Scope
This is the *detection* story, not the *fix-the-drift* story. The reconcile pass should:
- Run at startup (after CRDT replay, before serving requests)
- Compare each story's stage across all four sources
- Emit structured log lines for each drift type (CRDT-only, FS-only, DB-only, stage mismatch, etc.)
- Optionally surface a count to the matrix bot startup announcement (e.g. "⚠️ 3 stories have CRDT/DB drift — see logs")
The actual *fix-the-drift* logic (what to do when drift is detected) is a separate, larger story.
## Acceptance Criteria
- [ ] At server startup, after CRDT replay, a reconcile_state() function runs that walks all four state sources and detects drift
- [ ] Each drift type is logged with a structured line: e.g. `[reconcile] DRIFT story=X crdt_stage=Y db_stage=Z fs_stage=W` (or `MISSING` for absent)
- [ ] If any drift is detected, the matrix bot startup announcement includes a count and a suggestion to check the server logs
- [ ] The reconcile pass completes in < 1 second for a typical pipeline (~100 stories) so it doesn't slow startup meaningfully
- [ ] Tests cover: no drift (clean state), CRDT-only story, DB-only story, FS-only story, stage mismatch between CRDT and DB
- [ ] Documentation in README.md explains the reconcile pass and what each drift type means
- [ ] The pass is opt-out via a config flag in case it produces noise during the migration window

# Story 514: delete_story should do a full cleanup (CRDT op + DB row + filesystem shadow + worktree + pending timers)
## User Story
**Depends on story 520** (typed pipeline state machine). With 520 in place, `delete_story` becomes a single typed transition (`* → Archived(Abandoned)` or a hard-delete CRDT op) followed by event subscribers that handle the worktree, timers, and filesystem cleanup. This story should be re-shaped as the consumer migration once 520 lands.
---
**Note:** content stuffed into user_story per bug 509 workaround.
## Context
The MCP `delete_story` tool currently only **removes the filesystem markdown** from `.huskies/work/N_stage/`. It does NOT:
- Remove the row from `pipeline_items`
- Write a CRDT delete op to `crdt_ops`
- Tear down the in-memory CRDT entry
- Remove the `.huskies/worktrees/N_…/` worktree
- Cancel any pending rate-limit retry timers in `.huskies/timers.json`
So after `delete_story`, the story keeps appearing in `get_pipeline_status` (because the in-memory CRDT still has it), the timer fires and re-spawns an agent, the agent runs in the still-existing worktree, and the user has no idea why the "deleted" story keeps coming back.
## Real user story
As a user calling `delete_story` (via MCP, web UI, or chat command), I want a complete tear-down of all state associated with that story across every layer, so the story is actually gone — no in-memory cache entries, no pending agents, no timers, no worktree, no shadow files, no future spawns.
## Observed 2026-04-09
Repeatedly throughout the session. The most concrete example was around 17:20: I called `delete_story 478_…`, the tool returned success, the markdown file at `.huskies/work/1_backlog/478_…md` was removed, but at 17:25:17 the rate-limit retry timer fired and **re-spawned a coder-1 on the deleted story** because the worktree still existed, the pipeline_items row still existed, and the timer entry still existed in `.huskies/timers.json`. We then had to do sqlite surgery + manual worktree removal + manual timers.json edit to actually kill 478.
## Implementation note
The current `delete_story` is on the legacy filesystem path. The fix needs to wrap it in a transaction that touches every layer:
1. Cancel any pending timers for this story_id (read timers.json, filter, write back)
2. Stop any running/pending agents for this story_id (call `agent_pool.stop_agent` for each)
3. Remove the worktree if it exists (`git worktree remove`)
4. Write a CRDT delete op (`apply_and_persist` with a delete op)
5. Wait for the persist task to confirm
6. Delete the row from `pipeline_items` directly (or trust the materialiser to drop it)
7. Remove the filesystem shadow
Each step should be best-effort with logging — partial failures should be visible, not silent.

- [ ] Each tear-down step has its own log line so partial failures are diagnosable
- [ ] If any tear-down step fails, the tool returns an error with which step failed and what was already torn down (so the user can finish the cleanup manually)
- [ ] After delete_story, the story does NOT appear in get_pipeline_status, the web UI, or list_agents
- [ ] After delete_story, no rate-limit retry timer can re-spawn an agent on the deleted story
- [ ] Regression test using the 2026-04-09 repro: schedule a rate-limit timer for the story, call delete_story, fast-forward 5 minutes, assert no agent spawned

# Story 515: Add a debug MCP tool to dump the in-memory CRDT state for inspection
## User Story
**Note:** content stuffed into user_story per bug 509 workaround.
---
## Context
When diagnosing CRDT/state issues today, we had no way to look at the **in-memory** CRDT state directly. The closest available views were:
-`get_pipeline_status` — gives a summarised pipeline-shaped view (active/backlog/done) but hides the raw item structure, the index map, the lamport clock state, etc.
- Querying `crdt_ops` directly via sqlite — gives the *persisted* state, which can diverge from the in-memory state (we saw this with bug 511, where post-restart writes use reset seq counters)
-`read_item(story_id)` in `crdt_state.rs` — exists, returns a `PipelineItemView`, but is not exposed via MCP or HTTP
The result: every time I needed to check the CRDT state, I was either inferring it from `get_pipeline_status` (lossy) or querying the persisted ops (lagging the in-memory state). Neither gave me the ground truth.
## Real user story
As a developer debugging huskies state issues, I want an MCP tool (or HTTP debug endpoint) that returns a structured dump of the in-memory CRDT state, so I can see exactly what the running server thinks is true without inferring from summaries.
## Suggested API
- Tool name: `mcp__huskies__dump_crdt`
- Args: optional `story_id` filter (single story) or no args (dump everything)
- Returns: JSON with one entry per item containing: `story_id`, all field values (`stage`, `name`, `agent`, `retry_count`, `blocked`, `depends_on`), the CRDT path/index bytes (for cross-referencing with `crdt_ops`), the local lamport seq counter, and a flag indicating whether the item is `is_deleted`
- Returns metadata: total item count, current local seq counter value, count of pending ops in `persist_tx` channel (if observable)
## Observed 2026-04-09
This story would have saved us significant debugging time. Specific examples:
- When 478 was missing from `get_pipeline_status` after the manual sqlite insert, we had to infer "the API reads from in-memory CRDT, not from pipeline_items" by looking at source code. A `dump_crdt 478_…` call would have returned "not found" immediately, confirming the same conclusion.
- When 503 was showing at stage=merge in the API but only had a creation op at stage=1_backlog in `crdt_ops`, we had to manually search for content-indexed update ops to figure out where the post-restart updates went. A dump tool showing the current in-memory state vs the persisted op count would have made the divergence obvious.
## Acceptance Criteria
- [ ] New MCP tool `dump_crdt` is registered and callable
- [ ] With no args, returns all items in the in-memory CRDT as a structured JSON list
- [ ] With a story_id arg, returns just that one item (or null if not found)

# Story 516: update_story.description should create the ## Description section if it doesn't exist (instead of erroring)
## User Story
**Note:** content stuffed into user_story per bug 509 workaround.
---
## Context
The MCP `update_story` tool's `description` parameter "replaces the `## Description` section content". If the section doesn't exist in the story file, the call **errors out** with `Section '## Description' not found in story file.`
This becomes a real problem when:
1. A story was created via `create_story` (which is buggy per 509 and writes a stub template with no `## Description` section)
2. The user later wants to add a description via `update_story`
3. The update fails with the cryptic "section not found" error
We hit this exact scenario today: after bug 509 dropped the descriptions of 6 stories (500, 504, 505, 506, 507, 508), I tried to recover them by calling `update_story` with `description=...` — and the call errored out because the stub template the buggy `create_story` had written had no `## Description` section. We had to fall back to stuffing everything into the `user_story` field.
## Real user story
As a user calling `update_story.description` on any story (regardless of how it was originally created), I want the call to either replace the existing `## Description` section OR create one if it doesn't exist, so I never have to think about the template structure.
## Implementation note
The simplest fix is in the `update_story_in_file` (or equivalent) function: when looking for the `## Description` section, if not found, **insert it** at a sensible location — probably between `## User Story` and `## Acceptance Criteria` — and then write the description content there.
Related: this story partially covers the workaround for bug 509 (create_story drops description). If 509 is fixed first, the templates would always have a `## Description` section and this wouldn't matter. But this fix is still valuable for older stories created before 509 lands, AND for stories created via legacy paths that don't use the canonical template.

# Story 517: Remove filesystem-shadow fallback paths from lifecycle.rs (finish the migration to CRDT-only)
## User Story
**Depends on story 520** (typed pipeline state machine). Once 520 lands and consumers are migrated to the typed transition API, the lifecycle module no longer needs filesystem fallbacks — all state changes go through the typed `transition` function and the event bus. This story becomes the natural cleanup pass after 520 + 512 + 514 land.
---
**Note:** content stuffed into user_story per bug 509 workaround.
## Context
`server/src/agents/lifecycle.rs::move_item` (the helper that backs `move_story_to_current`, `move_story_to_done`, `move_story_to_merge`, etc.) has **three execution paths**:
1.**CRDT-first path** (the "happy" post-migration path) — calls `crdt_state::read_item(story_id)`, then `db::move_item_stage`, which writes a CRDT op and broadcasts events
2.**Content-store fallback** — if the story isn't in CRDT but exists in the db's content store, import it via `db::write_item_with_content`
3.**Filesystem fallback** — if neither, scan `.huskies/work/N_stage/` for a markdown file, import it to the DB
Paths 2 and 3 are **migration scaffolding**. They were necessary while stories existed only on disk and the CRDT was empty, but post-491/492 they should be unnecessary. Worse, they actively *cause* drift today:
- The filesystem fallback can re-import stale shadow files into the DB, undoing intentional deletes
- The path 3 search is blind to which stage a story "should" be in per the DB — it picks whatever stage dir has the file, which can promote stale shadows
- This is the mechanism that makes bug 510 (split-brain shadow promotion) possible
`move_story_to_current` is hardcoded to read from `["1_backlog"]`, which is also part of the same legacy filesystem assumption.
## Real user story
As a developer maintaining huskies, I want the lifecycle code to operate exclusively on the CRDT/DB and never touch filesystem shadows, so state drift is eliminated and the post-migration architecture is consistent.
## Implementation plan
1. Inventory every code path in `lifecycle.rs` that touches the filesystem under `.huskies/work/`
2. For each, determine whether it's a *read* (legacy fallback — can be removed if we're confident all stories are in CRDT now) or a *write* (legacy mirror — can be deferred to a separate filesystem-renderer task that derives state from CRDT)
3. Remove the read fallbacks
4. Move the writes to a downstream materialiser task that writes the filesystem shadows from CRDT events (so they're strictly read-only renderings)
5. Run the bug-510 reconcile pass at startup (story TBD) before this lands, to ensure no story is stranded with only a filesystem shadow
## Observed 2026-04-09
We watched the filesystem fallback paths cause harm multiple times today:
- Bug 510 split-brain: filesystem shadows in `1_backlog/` got re-promoted by timer fires after the DB had already moved the story to `5_done`
- The 478 worktree's `move_story_to_current` no-op'd because there was no `1_backlog` shadow — even though 478 was in `4_merge` per the DB (this was actually correct behaviour given the function's narrow `from = ["1_backlog"]`, but it surfaces how filesystem-bound the function is)
- Lifecycle moves were happening on the filesystem without writing CRDT ops (we initially mis-diagnosed this as "no transition ops in CRDT" before finding bug 511)
## Context
`server/src/agents/lifecycle.rs::move_item` (the helper that backs `move_story_to_current`, `move_story_to_done`, `move_story_to_merge`, etc.) has **three execution paths**:

2.**Content-store fallback** — if the story isn't in CRDT but exists in the db's content store, import it via `db::write_item_with_content`
3.**Filesystem fallback** — if neither, scan `.huskies/work/N_stage/` for a markdown file, import it to the DB

## Observed 2026-04-09
We watched the filesystem fallback paths cause harm multiple times today:
- Bug 510 split-brain: filesystem shadows in `1_backlog/` got re-promoted by timer fires after the DB had already moved the story to `5_done`
- The 478 worktree's `move_story_to_current` no-op'd because there was no `1_backlog` shadow — even though 478 was in `4_merge` per the DB (this was actually correct behaviour given the function's narrow `from = ["1_backlog"]`, but it surfaces how filesystem-bound the function is)
- Lifecycle moves were happening on the filesystem without writing CRDT ops (we initially mis-diagnosed this as "no transition ops in CRDT" before finding bug 511)
## Acceptance Criteria
- [ ] Inventory of every filesystem touch in lifecycle.rs is documented in the story body or a follow-up comment
- [ ] All read fallbacks in lifecycle.rs (paths 2 and 3 above) are removed
- [ ] All write paths in lifecycle.rs that mirror to the filesystem are moved to a separate materialiser task driven by CRDT events
- [ ] After the change, lifecycle.rs has zero direct std::fs:: calls under .huskies/work/
- [ ] move_story_to_current no longer hardcodes from=['1_backlog'] — it reads the source stage from CRDT
- [ ] Regression: the existing 'try filesystem fallback' tests are updated to test the new CRDT-only path instead of being deleted
- [ ] A pre-flight script verifies all existing stories are in CRDT before this change lands (so nothing gets stranded)
- [ ] Bug 510 (split-brain shadows) no longer reproduces after this change
The `let _ = ...` discards the return value of `send()`. If the channel is closed (because the persistence task panicked, was shut down, or has dropped its receiver), the op is silently dropped from persistence — but the in-memory CRDT is already updated. The next restart will replay only the persisted ops, and the in-memory state will quietly diverge from the persisted state.
This is also one of the candidate causes for some of the state drift we've been chasing. It's hard to rule out because there's no log line to confirm whether the persist task is still alive or whether sends are succeeding.
## Real user story
As a developer or operator, I want any failure of `persist_tx.send()` to be logged immediately at WARN or ERROR level, so silent persistence loss is detectable instead of invisible.
## Observed 2026-04-09
Spent significant time investigating whether persist sends were silently failing. Eventually ruled it out empirically (we found that ops WERE being persisted, just with reset seq counters per bug 511). But the diagnosis would have been minutes instead of an hour if there was a log line to check.
"[crdt] Failed to send op to persist task: {e}; persist task may be dead. \
In-memory state is now ahead of persisted state."
);
}
```
Apply the same fix at every `let _ = state.persist_tx.send(...)` site in crdt_state.rs (there are at least 2 — one in apply_and_persist, one in apply_remote_op).
## Acceptance Criteria
- [ ] Every call site of `state.persist_tx.send(...)` in crdt_state.rs logs at ERROR level on send failure
- [ ] The error message includes the channel error and a clear note that 'in-memory and persisted state may have diverged'
- [ ] Unit test: shut down the persist receiver (drop the rx end), call write_item, assert an error is logged
- [ ] No regression in the happy path (no extra log lines on success)
- [ ] Consider: also expose a counter / metric for persist send failures so it can be monitored without grepping logs

# Story 519: mergemaster should detect no-commits-ahead-of-master and fail loudly instead of exiting silently
## User Story
**Depends on story 520** (typed pipeline state machine). Once 520 lands, this story largely *evaporates*: `Stage::Merge` is defined as `Merge { feature_branch: BranchName, commits_ahead: NonZeroU32 }`, so a merge state with zero commits ahead is **structurally unrepresentable**. The transition `Current → Merge` (or `Qa → Merge`) is required to provide a NonZeroU32 — the type system enforces it. This story remains useful as a *defensive runtime check* during the migration window before 520 lands; afterwards, it should be closed as redundant.

**Note:** content stuffed into user_story per bug 509 workaround.
## Context
When mergemaster runs on a story whose worktree has **zero commits ahead of master** (e.g. because `create_worktree` always creates from master and the original feature branch was never checked out into the worktree), it currently:
1. Spawns its claude session
2. Runs `merge_agent_work` MCP tool
3. Finds nothing to merge
4. Exits cleanly with `[agent:N:mergemaster] Done. Session: ...`
5.**Does not log any error or warning**
6.**Spends real money** on the empty session — we observed `cost=$0.82` for one such no-op run
The user has no signal that the merge didn't actually happen. The matrix bot fires a "QA → Merge" stage notification (because the story did move stages internally), then nothing — no `🎉 Merge → Done` notification follows. Master is unchanged.
## Real user story
As a user watching the pipeline, I want mergemaster to detect "this worktree has no commits ahead of master" *before* spending money on a Claude session, and fail loudly with a clear error so I know to investigate the upstream cause (probably the worktree got reset to master).
## Observed 2026-04-09
Around 18:31:51, mergemaster spawned for 478 in a worktree that had been reset to master by the orphan cleanup logic at 18:29:54. By the time mergemaster ran, the worktree was on master with zero commits ahead. It ran a session, spent $0.82, exited "Done", and didn't merge anything. We didn't notice for several minutes because the failure was completely silent. We had to manually `git log master..feature/story-478_…` to confirm there was no merge commit on master.
## Fix
In mergemaster's startup sequence (probably in advance.rs or wherever the mergemaster session is spawned), add a pre-flight check:
"[mergemaster] worktree {worktree_path} has no commits ahead of master; \
refusing to spawn merge session. Likely cause: worktree was reset to \
master after the feature branch's commits were created. Investigate the \
worktree's git state before retrying."
);
returnErr("no commits to merge".into());
}
```
This costs ~milliseconds (one git command) and saves the cost of an entire Claude session per false-positive.

```
This costs ~milliseconds (one git command) and saves the cost of an entire Claude session per false-positive.
## Acceptance Criteria
- [ ] Before mergemaster spawns its Claude session, it runs `git log master..HEAD --oneline` (or equivalent) on the worktree
- [ ] If the result is empty (zero commits ahead), mergemaster exits early with an ERROR log line and does NOT spawn the session
- [ ] The error message is specific enough that the user can diagnose the upstream cause (e.g. mentions 'worktree was reset' and suggests checking the worktree's branch)
- [ ] The matrix bot sends a clear failure notification (NOT a successful 🎉 emoji) when this happens
- [ ] The story does not advance to a 'done' state when mergemaster exits this way; it stays in 4_merge with a clear blocked status
- [ ] Regression test: create a worktree on master (no feature commits), invoke mergemaster, assert the early exit happens and no Claude session is spawned
- [ ] Cost saving observed in the 2026-04-09 incident ($0.82 per no-op session) is documented in the test as the motivation

# Story 520: Typed pipeline state machine in Rust (foundation: replaces stringly-typed CRDT views with strict enums, subsumes 436)
## User Story
**Note:** content stuffed into user_story per bug 509 workaround.
---
## Context
Today huskies represents pipeline state as a loose JSON document inside the BFT JSON CRDT. Each story has fields like `stage: String`, `agent: String`, `retry_count: f64`, `blocked: bool`, `depends_on: String` (JSON-encoded list, double-encoded). This stringly-typed representation allows **many impossible states** to be representable in the data model:
-`stage = "9_invalid"` — typo, no compile error
-`stage = "5_done"` + `blocked = true` — a done story is blocked? what does that mean?
-`stage = "4_merge"` with no commits ahead of master — the silent mergemaster failure mode (today's story 478)
- A coder agent assigned to a story in `4_merge` — bug 502, the loop we fought all day today
-`retry_count = 3.7` — fractional retry counts (it's an f64 because that's what JSON CRDTs do)
-`agent = "coder-1"` AND `stage = "1_backlog"` — backlog story has an agent? sentinel encoding via empty string
Multiple bugs filed today (501, 502, 510, 511) exist *because* the type system can't enforce the pipeline invariants. **Patching individual symptoms forever is the wrong strategy.** The right strategy is to make impossible states unrepresentable at the Rust type level, using a typed state machine layered on top of the loose CRDT. The CRDT can stay loose at the persistence layer (it has to be — that's what makes it merge correctly across nodes), but every consumer above the CRDT operates on strict typed enums.
## Real user story
As a developer working on huskies, I want the pipeline state to be expressed as a strict Rust state machine where impossible states and impossible transitions are compile-time errors, so future bugs in this category become structural rather than runtime drift.
## Design
### Two enum hierarchies
**Synced state (CRDT-backed, converges across nodes):**
The execution state lives in the CRDT under **each node's pubkey**. Each node only writes to entries where `node_pubkey == self.pubkey`, so there's no merge conflict — concurrent writes from the same author follow LWW, concurrent writes from different authors target different entries entirely. All nodes can READ all execution states across the mesh.
**This per-node-keyed CRDT pattern enables:**
- **Cross-node observability** — matrix bot can show "node A is running coder-1 on story X, node B is rate-limited on story Y"
- **Heartbeat detection** — if a node hasn't updated its execution_state in N minutes, the entry is "stale" (laptop closed, process crashed, oom kill, etc.)
- **Foundation for story 479** (CRDT work claiming) — a node knows what other nodes are doing *before* claiming work
- **Stuck job recovery** — if node A's heartbeat dies mid-run, node B can see the stuck state and decide whether to take over
- **Crash forensics** — the last persisted ExecutionState before a crash is preserved in CRDT, accessible from any node
### The transition function
```rust
fntransition(
state: PipelineItem,
event: PipelineEvent,
)-> Result<PipelineItem,TransitionError>
```
Pure function. Takes the current state and an event, returns either the new state or a TransitionError. The compiler enforces that the result of every transition is structurally valid — you can't construct a `Stage::Merge` without `commits_ahead: NonZeroU32`, you can't construct a `Stage::Done` without a `merge_commit: GitSha`, etc.
**The set of valid transitions is small** (roughly 10):
Each subscriber is independent and concerns itself only with its own dispatch. Adding a new side effect = adding a new subscriber, not editing the transition function. **The "many things happen on state changes" complexity moves out of the state machine and into the bus consumers**, where each piece is testable in isolation.
### Projection layer (loose CRDT ↔ typed Rust)
The bft-json-crdt JSON document is the persistence layer. The typed enums are the application layer. A projection function bridges them at one carefully-controlled boundary:
When the CRDT contains data the typed layer can't parse (e.g. a stage value from a future huskies version, OR a merge that produces an inconsistent intermediate state), `try_from` returns a `ProjectionError`. The error surfaces to the caller — it doesn't silently propagate as garbage. The validation happens at exactly one point: the projection boundary.
## What this subsumes
**Story 436** ("Unify story stuck states into a single status field") is subsumed by the `Stage::Archived { reason: ArchiveReason }` variant. The unified status field IS the `ArchiveReason` enum. Story 436 is marked superseded by this story.
## What this enables (concrete bug eliminations)
- **Bug 502** becomes unrepresentable: there's no way to construct `Stage::Merge` with a Coder agent — Coder agents only attach to `Current` / `Qa` stages, and that constraint is in the type signature of the transition function.
- **Bug 510** becomes irrelevant: there's no "stage='1_backlog' filesystem shadow vs stage='5_done' DB" drift, because Stage is a typed enum with a single source of truth (the CRDT), and projections are derived deterministically.
- **Bug 519** (mergemaster silent on no-op merge) becomes unrepresentable: `Stage::Merge` requires `commits_ahead: NonZeroU32`. You can't construct a Merge state with zero commits.
- **Bug 511** (lamport seq reset) becomes detectable: the projection layer notices when CRDT data fails to parse cleanly and surfaces a ProjectionError instead of silently producing garbage in-memory state.
- **Story 479** (CRDT work claiming) has a clean foundation: ExecutionState gives every node visibility into what every other node is doing, including stale-heartbeat detection.
- **Future state machine bugs become compile errors**, not runtime drift.
## Implementation order
1. Define the `Stage`, `ArchiveReason`, `ExecutionState`, `PipelineItem` types in a new module (e.g. `server/src/pipeline_state.rs`).
2. Implement the projection layer (try_from / from for PipelineItemCrdt).
3. Implement the `transition` function with exhaustive valid transitions.
4. Implement the event bus.
5. Migrate consumers ONE AT A TIME — chat commands, lifecycle, API, auto-assign, matrix bot. Each migration is isolated; the compiler tells you when you've missed something.
6. Once nothing reads the loose `PipelineItemView` anymore, delete it.
7. Story 436 closes when this lands.
## Acceptance Criteria
- [ ] A new module (e.g. server/src/pipeline_state.rs) defines the Stage, ArchiveReason, ExecutionState, and PipelineItem types with the variants described in the design
- [ ] Stage::Merge has a NonZeroU32 commits_ahead field (so the bug 519 silent no-op merge is unrepresentable)
- [ ] Stage::Done has GitSha merge_commit and DateTime merged_at fields (so a 'done' story always has merge metadata)
- [ ] ArchiveReason enum subsumes the old blocked / merge_failure / review_hold front matter fields, with a sub-reason variant for each
- [ ] PipelineItem.depends_on is Vec<StoryId>, not String (no more JSON-as-string)
- [ ] ExecutionState lives in the CRDT under per-node-pubkey keys; each node only writes to its own subspace (validated by CRDT signature check)
- [ ] Last_heartbeat field is updated periodically by the running node so other nodes can detect stale entries
- [ ] A pure transition(state, event) -> Result<PipelineItem, TransitionError> function exists and is exhaustively pattern-matched
- [ ] Every valid transition listed in the design (~10) is implemented and unit-tested with both success and error cases
- [ ] The TryFrom<&PipelineItemCrdt> for PipelineItem projection function handles every currently-valid CRDT state and returns a structured ProjectionError for invalid ones (instead of silently propagating garbage)
- [ ] An event bus pattern is in place where matrix bot, filesystem renderer, pipeline_items materialiser, auto-assign, and web UI broadcaster are independent subscribers
- [ ] All call sites that previously read item.stage as a string or used the blocked / merge_failure / review_hold fields are migrated to the typed enum API
- [ ] Story 436 is closed as superseded by this story
- [ ] Bug 502 has a regression test that confirms the type system prevents the loop (the test should be a compile-fail test if possible)
- [ ] Bug 510 (filesystem shadow split-brain) no longer reproduces after this lands, because the typed state machine has a single source of truth
- [ ] Documentation in README.md or a new ARCHITECTURE.md explains the type hierarchy, the transition function, the event bus pattern, and the per-node ExecutionState convention

# Story 521: MCP/HTTP capability to write a CRDT tombstone (delete op) for a story, to clear it from in-memory state
## User Story
**Note:** content stuffed into user_story per bug 509 workaround.
---
## Context
Today (2026-04-09) we discovered the hard way that **there is no way to remove a story from huskies's running in-memory state without restarting the server process**. The state machines that keep stories alive include:
1. The persisted CRDT op log (`crdt_ops` table) — direct sqlite DELETE works
2. The in-memory CRDT view (`CRDT_STATE` global in `server/src/crdt_state.rs`) — **no eviction API**
3. The in-memory content store (`CONTENT_STORE` in `server/src/db/mod.rs:46`) — has `delete_content()` but no MCP / HTTP exposure
4. The shadow `pipeline_items` table — direct sqlite DELETE works
5. Filesystem shadows under `.huskies/work/` — `find -delete` works
6.`timers.json` — direct file edit works
If a story gets into a bad state (split-brain, ghost row, runaway timer respawning it), we can scrub all the *persistent* layers (1, 4, 5, 6) but the *in-memory* layers (2, 3) keep regenerating it because some periodic code reads in-memory state and writes new ops based on what it sees. The only way to clear in-memory state today is `docker restart huskies`, which is heavy and disrupts the matrix bot, web UI, and any in-flight agents.
We need a **scoped, surgical capability** to write a CRDT tombstone op for a single story_id, which:
- Marks the in-memory item as `is_deleted = true`
- Persists the tombstone op to `crdt_ops` so future replays don't resurrect the story
- Removes the story from `CONTENT_STORE`
- Cleans up any pending `timers.json` entries for the story
- Cancels any running agents on the story
…and exposes it as an MCP tool (e.g. `mcp__huskies__purge_story`) and ideally an HTTP endpoint, so an operator can "kill it with fire" without restarting the server.
## Real user story
As a huskies operator, I want a single MCP/HTTP call that completely removes a story from every layer of state — persistent AND in-memory — so I never have to restart the entire server just to clean up one stuck story.
## Observed 2026-04-09
We spent the last hour of this session whack-a-moling stories 503 and 478. Even after:
-`DELETE FROM pipeline_items WHERE id LIKE '503%'` ✓
-`DELETE FROM crdt_ops WHERE op_json LIKE '%503_bug_depends_on%'` ✓
-`mcp stop_agent + remove_worktree` for the running coders ✓
-`find .huskies/work -name '503_*' -delete` ✓
- emptying `timers.json` (multiple times — kept getting re-populated) ✓
…503 kept reappearing in `current` with new agents being spawned. The root cause: the in-memory `CRDT_STATE` (loaded from `crdt_ops` at startup at 18:19) still had 503 and 478 as live items, and a periodic code path was reading `crdt_state::read_all_items()`, seeing them as live, and triggering the auto-assign / rate-limit-retry chain.
Final resolution: `docker restart huskies` to wipe the in-memory state. Worked, but it's a sledgehammer.
## Implementation note
The bft-json-crdt library appears to support per-item delete via the `is_deleted: bool` field on each CRDT item (visible in the persisted op JSON we inspected today). Writing a delete op should look something like:
```rust
crdt_state::apply_and_persist(&mutstate,|s|{
s.crdt.doc.items[idx].delete()// or whatever the BFT JSON CRDT delete API is
})
```
The op gets signed, applied to the in-memory state (marking the item deleted), and persisted to crdt_ops via the existing channel. Then `read_all_items()` should filter out `is_deleted: true` entries (it may already do this — verify in `extract_item_view`).
## Why this is distinct from bug 514 (delete_story full cleanup)
Bug 514 is about making the existing `delete_story` MCP tool do a full cleanup across all the layers we know about. **This** story is specifically about acquiring the *capability* to write a CRDT tombstone — without that, bug 514 can't be implemented correctly because it has no way to clear in-memory state. So 521 is a prerequisite for 514.
It's also a prerequisite for properly handling the fix for bug 510 (split-brain shadows) — when the reconcile pass detects a stale story, it needs a way to actually evict it. That eviction is what this story provides.
## Acceptance Criteria
- [ ] A new MCP tool (e.g. `mcp__huskies__purge_story`) is registered and callable
- [ ] The tool takes a story_id and returns a structured result indicating which layers were cleared (CRDT op, content store, timers, agents, worktree, filesystem)
- [ ] The tool writes a signed CRDT tombstone op (is_deleted: true) for the item, applies it to the in-memory CRDT, and persists it to crdt_ops
- [ ] After the tool runs, `read_all_items()` does NOT return the purged story (verify the filter handles is_deleted)
- [ ] After the tool runs, `read_content(story_id)` returns None (CONTENT_STORE entry is removed)
- [ ] After the tool runs, `timers.json` has no entries for the story
- [ ] After the tool runs, no agents are running on the story (stop_agent is called for any active ones)
