feat: add dispatch preflight/init validation step (duplicate-work check + workflow-store smoke test) - #596
Merged
Conversation
Duplicate-work detection (pre-claim): before dispatching an item, find_duplicate_pr searches GitHub for a PR already carrying the item's 'for item #N' marker. A merged match self-heals the item to completed and cleans up its worktree instead of letting a redispatch re-do already-merged work (the near-miss from items #122/#156, where tracked state fell out of sync with a merged PR). An open match skips dispatch and flags for human review instead of racing a second PR. Workflow-store smoke test: flare_workflow::smoke_test does a real save/delete/load round-trip against the actual on-disk SqliteStore schema. Wired into daemon boot (dashboard::server::run) and into dev_install::run via a new hidden 'daemon workflow-store-smoke-test' subcommand, run against the freshly built binary right after a binary swap -- the exact trigger (item #576) that let a broken delete_state go undetected for ~33h. On failure, refuses dispatch instead of letting every claimed item retry-and-fail silently into a stuck state. src/cli/work.rs is frozen at the LOC gate's 2100-line limit, so the new duplicate-PR logic and its tests live in their own included files (work_duplicate_pr.rs, work_duplicate_pr_tests.rs) rather than growing work.rs itself.

Inline comments:
In `@crates/flare-workflow/src/sqlite_store.rs`:
- Around line 890-927: The regression test schema must let save succeed while
making delete_state fail: retain workflow_runs.id to match write_state, and move
the intentional identifier mismatch to a child table such as journal. Update the
CREATE TABLE statements in the smoke test so deletion reaches the child-table
SQL failure and verifies delete_state reports it.
In `@src/cli/work_duplicate_pr.rs`:
- Around line 63-66: Update the completion flow around mark_completed so a
database error or false result produces a failed outcome instead of continuing
as success. Only post the auto-complete comment, release the claim, disarm the
guard, and return exit code 0 after completion is confirmed; otherwise propagate
the failure and preserve retry behavior.
- Around line 99-107: Update the release handling in the work-duplicate flow
around ClaimGuard and item_release to inspect the release result, disarm
ClaimGuard only after successful release, and return the failure while leaving
the guard armed when item_release fails. Preserve notification behavior only for
the successful-release path.
- Around line 31-35: Update pick_duplicate_pr in src/cli/work_duplicate_pr.rs at
lines 31-35 to prioritize merged PRs, then select only an open PR by requiring
state == "open"; closed, unmerged PRs must not be returned. Update
src/cli/work_duplicate_pr_tests.rs at lines 1-10 to use an open PR for the
non-merged case and add coverage confirming a closed-unmerged PR returns None.
In `@src/dashboard/server.rs`:
- Around line 771-807: Move the flare_workflow::smoke_test gate to before
workflow registration and engine().recover(), ensuring no recovered workflows
can execute when the store is invalid. On smoke-test failure, skip recovery,
worker-pool startup, and supervisor ticks while continuing dashboard-only
startup; preserve normal registration, recovery, and dispatch when the test
succeeds.
In `@src/dev_install/mod.rs`:
- Around line 197-208: Update verify_workflow_store to use the same spawn,
try_wait, and kill timeout loop as verify_runs, applying VERIFY_TIMEOUT so a
hung workflow-store-smoke-test process is terminated and reported instead of
blocking indefinitely.
In `@src/github/pulls.rs`:
- Around line 73-81: Update the marker-search flow to use get_paginated with an
extractor for the items array, ensuring all search-result pages are processed
before mapping numbers through get. Add a test covering 100 first-page results
and a matching pull request on page two.

Keep ClaimGuard armed when claim release fails.
Line 99 discards an item_release error, but Line 107 always disarms the guard. If release fails, ClaimGuard::drop cannot perform its release backstop and the item can remain claimed.
Check the release result. Disarm only after a successful release. Otherwise return failure with the guard armed.

…andling, smoke-test ordering Addresses 6 CodeRabbit findings on PR #596, all independently verified against the actual code before fixing: - pick_duplicate_pr: a closed-but-unmerged PR was treated the same as a genuinely open one, permanently blocking a legitimate redispatch. Now filters to merged-or-open only. - handle_duplicate_pr: a failed/unconfirmed mark_completed was silently reported as success (comment posted, claim released, exit 0). Now returns a retryable failure and leaves the claim armed instead. - handle_duplicate_pr: item_release's result was discarded and claim_guard was disarmed unconditionally, so a failed release left nothing to retry it. Now only disarms on confirmed release success. - dashboard::server::run: engine().recover() ran before the workflow-store smoke test, so a broken store could still be touched by recovery before validation. Reordered so recovery is gated behind the smoke test too. - dev_install::verify_workflow_store: used a blocking Command::status() with no timeout, unlike its sibling verify_runs. Now uses the same spawn/try_wait/kill-with-deadline pattern. - github::pulls::find_by_item_marker: the search API call was unpaginated (GitHub's default page size is 30), so a matching PR beyond the first page would silently not be found. Now uses the existing get_paginated helper. Also fixes the schema-mismatch regression test in sqlite_store.rs: it put the intentional id/run_id mismatch on workflow_runs itself, so write_state failed on save and delete_state's own failure path was never actually exercised. Moved the mismatch to journal (write_state never touches it for an empty smoke-test state) and strengthened the assertion to confirm the failure comes from there. New tests: pick_duplicate_pr_ignores_a_closed_unmerged_pr, pick_duplicate_pr_selects_a_genuinely_open_pr_when_no_merged_match_exists. Verified: cargo build, cargo test --bin agentflare (1548/1548 passing), cargo test -p flare-workflow (all passing), cargo fmt --check, cargo clippy (CI's exact flags), scripts/loc-gate.sh.

engine().register_workflow()/recover() failures were only logged -- the worker pool and both supervisor ticks still started regardless, undermining the smoke-test gate's own fail-closed contract one level up: dispatch could start against pipeline state that's already known to be broken. Also fixes a compile error from the prior commit: recover() returns Result<Vec<WorkflowRunId>, WorkflowError>, not Result<(), _>.

Fixes item #164.
Motivated by two incidents from the same session: item #163 fixed a
delete_state()bug that silently broke 100% of dispatch for ~33h with no one noticing, and items #122/#156 were already completed via merged PRs but their tracked state never updated, so a routine redispatch nearly re-did the work — caught only because a human asked "are you sure these weren't already done?" and killed two live duplicate agent sessions mid-run.1. Duplicate-work detection (pre-claim)
find_duplicate_prsearches GitHub for a PR already carrying the item'sfor item #Nmarker (the footerworktree::pr_footerstamps onto every PR agentflare opens):2. Workflow-store smoke test
flare_workflow::smoke_testdoes a real save/delete/load round-trip against the actual on-diskSqliteStoreschema (not a mock). Wired in two places:dashboard::server::run).dev_install::run, via a new hiddendaemon workflow-store-smoke-testsubcommand run against the freshly built binary right after a binary swap — the exact trigger (item fix(flare-workflow): delete_state deletes workflow_runs by wrong column #576) that let a brokendelete_statego undetected for ~33h. This process is still running the old code, so only a subprocess of the new binary can prove the new code's storage layer actually works before anything overwrites the installed binary.On failure, refuses dispatch and surfaces a loud, operator-visible error instead of letting every claimed item retry-and-fail silently into a stuck state.
LOC gate note
src/cli/work.rsis frozen at the LOC gate's 2100-line limit. The new duplicate-PR logic and its tests live in their own included files (work_duplicate_pr.rs,work_duplicate_pr_tests.rs) sowork.rsitself stays at exactly 2100 lines.Provenance
This item went through ~62 hours and 438 dispatch attempts across multiple agent sessions (opencode and claude-code), repeatedly blocked by this same LOC gate on auto-commit plus several infrastructure failures (daemon restarts, auth expiry, a dispatch-storm bug retrying every ~12s). The implementation itself — both MVP pieces, with tests including a real-broken-schema smoke test — was already complete and correct in the stuck worktree; it just could never get past the commit step. Recovered from
.worktrees/task/164, re-applied cleanly onto current master, split to satisfy the LOC gate, and verified here.Verified:
