Introduces backend/.golangci.yml (27 linters across correctness, dead-code/
boilerplate, style, and security), wires it into CI as a blocking job, and
fixes every finding so the tree starts at zero.
Config:
- 27 linters: errcheck, govet, staticcheck, errorlint, bodyclose,
sqlclosecheck, rowserrcheck, nilerr, makezero, unused, unparam, unconvert,
wastedassign, copyloopvar, prealloc, dupl, revive (incl. exported-symbol doc
comments), gocritic, misspell, usestdlibvars, predeclared, nakedret, gosec, …
- Tuned for signal over noise: govet/shadow and gocritic hugeParam/rangeValCopy/
unnamedResult disabled (idiomatic-Go false positives); sqlc-generated code and
tests get scoped exclusions; gosec G304 excluded (paths are config/run-file/
worktree-derived, not user input); nilerr excluded in cli/status.go (probe
failures are the reported status, not a command error).
CI:
- New blocking lint job (golangci-lint-action, latest binary for Go-version
compatibility).
- go-version now read from go.mod (was pinned 1.22 while go.mod declares 1.25).
Cleanup to reach zero (no behavior change):
- errcheck: wrap deferred/inline Close()/Remove()/Rollback() with `_ =`.
- gosec: tighten dir/file perms (0755->0750, 0644->0600).
- unparam: drop always-nil error return from startLifecycle; drop unused
shellPath param (zellij PowerShell) and always-500 fallbackStatus param
(writeProjectError).
- gocritic: regexp \d, s != "", switch->if, combined appends.
- revive: doc comments on all exported symbols; rename project.ProjectRow ->
project.Row (stutter); rename `max` locals shadowing the builtin.

Adds backend/internal/integration with five end-to-end tests that hydrate the
real lifecycle.Manager + session.Manager against a tmp SQLite store and
exercise the full pipeline through the DB triggers and the CDC poller:
- TestHappyPath_Spawn_PR_Kill — spawn -> SCM PR observation (open + CI
passing) -> kill; asserts canonical row, pr row, and change_log event
types (session_created/_updated, pr_created, pr_check_recorded).
- TestRestoreRoundTrip_PreservesMetadata — spawn, kill, close store, reopen
same DB path, hydrate fresh LCM/SM, Restore(); asserts AgentSessionID and
the rest of SessionMetadata survive across the daemon restart.
- TestCIFailureAndRecovery_NudgeThenClears — failing CI observation drives
the CI-failed reaction nudge with the log tail injected; passing CI
observation switches to approved-and-green human notify; pr_checks history
reads back the failure (the brake's source of truth).
- TestDetectingPersistsAcrossRestart — failed probe parks the session in
detecting with detecting_* columns populated, round-trips across a
close/reopen, alive probe clears the quarantine memory.
- TestCDCPollerReceivesAllStages — drives the real cdc.Poller; asserts the
trigger pipeline emits each expected event_type and seq is monotonic.
Wiring gap fixed (minimal): goose v3 keeps baseFS/logger/dialect as
package-level globals, so two concurrent sqlite.Open() calls — uncommon in
production but normal under -race with t.Parallel() — race on
goose.SetBaseFS/SetLogger/SetDialect inside migrate(). Added a process-level
sync.Mutex around the migrate() call. ~11 lines, no signature changes.
Scope notes (the task brief assumed a fancier architecture than what
actually shipped in PR #37):
- No outbox / consumer_offsets / janitor exist on main — the change_log
table IS the durable, ordered source of truth (see cdc/event.go), so the
brief's janitor-watermark step is skipped.
- No reaction_trackers table / ReactionStore port — trackers are in-memory
per lifecycle/reactions.go; persistence-round-trip there is N/A.
- No revision column / Upsert(rec, eventType) — write-mutex serialises and
change_log.seq orders, so the assertions land on event_type + seq, not on
a per-row revision counter.
All 219 tests pass under -race across 18 packages. lifecycle/fakes_test.go
is untouched; existing unit tests still drive the in-memory fake.
Addresses review on PR-observation persistence:
- pr_checks now has an AFTER UPDATE CDC trigger (guarded on status change), so a
check flipping in_progress->failed on the same commit emits change_log instead
of updating silently. Restores symmetry with the sessions/pr triggers.
- writePR persists scalar facts + checks + comments in ONE transaction via
Store.WritePRObservation, so a mid-write failure can't leave the pr row (and
its CDC event) committed while checks/comments are partial. Collapses the
PRWriter port's three write methods into one WritePR.
- db.go: record why modernc.org/sqlite (pure-Go, CGO-free static binary) at the
import site.
Regression tests for both the update-trigger (emit on change, suppress no-op
re-poll) and the transactional write. go test -race ./... green.

Reworks the storage + CDC layer to the simplified design agreed in review:
Schema (one clean migration, 0001): projects, sessions, pr, pr_checks,
pr_comment, change_log. sessions.id is a single string key "{project}-{num}"
(mer-1); operational metadata folded into sessions; is_alive replaces the
runtime axis; no revision (the per-session write mutex serializes, change_log.seq
orders). pr keyed by URL (1 session : many PRs). pr_checks is CI run history
(one row per check per commit) — the CI-fix-loop brake is a LIMIT 3 query, no
counter stored. change_log carries a required project_id FK + nullable session_id.
CDC is DB-native: AFTER INSERT/UPDATE triggers on sessions/pr/pr_checks append
to change_log atomically with the change (json_object payloads). The old durable
outbox/JSONL/janitor pipeline is gone; the cdc package is now a Poller that reads
change_log and fans events out through the in-memory Broadcaster (hardened with
recover()). Clients catch up via the log from their own offset (SSE Last-Event-ID).
Storage uses a single writer connection + a reader pool (read-your-writes for the
triggers' subqueries; concurrent reads). sqlc-generated typed queries.
Tests (-race): CRUD, per-project id assignment, the loop-brake query, concurrent
creates, triggers populating change_log; CDC end-to-end through the real store,
concurrent goroutine delivery, broadcaster panic-isolation.
NOTE: scoped to storage + CDC. The lifecycle-engine consumers (decide, lifecycle,
session, reaper, main wiring) still reference the old domain axes and need a
follow-up integration pass to compile against the new model.

SetMaxOpenConns(1) forced every read (List/Get/GetPR/...) to queue behind
the single connection, so the dashboard's reads contended with the LCM's
writes. WAL already supports many concurrent readers, so raise the pool to 8
and instead serialize *writes* with a Store.writeMu. That keeps WAL's
single-writer rule and the revision-CAS read-then-write atomic regardless of
pool size, while reads now run in parallel across the pool.
Every write method takes writeMu (Upsert, PatchMetadata, UpsertPR/DeletePR,
the pr_check/pr_comment Replace* via inTx, the CDC outbox/offset writes,
project writes, reaction-tracker writes); reads take nothing. Added
TestConcurrentReadsAndWrites (16 writers + 16 readers) which passes under
-race.

Add the two real outbound adapters that replace the in-memory fakeStore:
internal/storage/sqlite (persistence satisfying ports.LifecycleStore) and
internal/cdc (transactional-outbox publisher, JSONL delivery, durable
consumer). Wire them into main.go alongside the Lifecycle Manager and reaper
so the write path is live end-to-end: LCM.Upsert -> store -> outbox -> JSONL
-> broadcaster.
Storage (internal/storage/sqlite):
- modernc.org/sqlite (pure Go, no CGO) for clean cross-compile; goose
embedded migrations; sqlc-generated typed queries under gen/.
- Atomic Upsert: session row + change_log + outbox written in one tx.
- revision is an optimistic-concurrency (CAS) check: insert requires
revision 0 and persists 1; update requires loaded revision == stored and
bumps +1; zero rows affected returns a revision-mismatch error.
- Metadata is an opaque map in session_metadata, off the CDC path.
- Durable reaction_trackers (fixes the in-memory-only escalation budget that
re-fired human pages on restart).
CDC (internal/cdc):
- Publisher drains the outbox to a JSONL log; size-based rotation with a
reset marker.
- Consumer tails via byte cursor, detects rotation (os.SameFile), resyncs
from a full-state snapshot on gaps, and tracks a durable consumer_offsets
cursor.
- Janitor reclaims acknowledged outbox rows.
- Broadcaster is the in-process fan-out port the FE transport will subscribe
to (WS/SSE wiring deferred).
Composition root (main.go + *_wiring.go):
- startCDC stands up publisher/consumer/janitor + broadcaster.
- startLifecycle constructs the LCM, makes escalation budgets durable via
WithReactionStore, teaches it to enumerate sessions via WithSessionLister,
and starts the reaper.
- Notifier, AgentMessenger, and the reaper's runtime registry are TEMPORARY
no-op/empty stubs (lifecycle_wiring.go) with TODO markers; see the PR
description for how to fill them in.
Tests: contract-parity, revision CAS, outbox atomicity, CDC ordering and
idempotency, rotation/resync, janitor vacuum, reaction durability across a
simulated restart, and composition-root adapters. gofmt/build/vet clean and
go test -race ./... green.
