* feat(plugin): add agents plugin (first iteration)
Faithful copy of the agents plugin implementation from yyovil/better-ao
(internal/plugin/ -> backend/internal/plugin/) plus its PRD
(prds/plugins/agents/PRD.md), as a first-iteration proposal for review.
Imports are left at their original github.com/yyovil/better-ao/... paths and
are NOT yet reconciled to this repo's module; see PR description for the
integration deltas (module path, missing internal/utils dependency).

* Move agent adapters under backend adapters
* Keep daemon ports and session out of adapter move
* Remove Better-AO naming from flake
* Keep flake as dev shell only
* Use goimports for local formatting
* Wire session manager to per-session agent adapters
Move the Agent port into internal/ports and have the claude-code and
codex adapters implement it directly, alongside their workspace-local
activity hooks and a manifest-keyed adapter registry. Rename
RuntimeConfig.LaunchCommand to Argv and update the tmux and zellij
runtimes to match.
The session Manager now resolves a real agent adapter per session via a
new ports.AgentResolver: from cfg.Harness on Spawn and the stored harness
on Restore, so one daemon runs claude-code and codex sessions side by
side. The daemon backs the resolver with the registry; AO_AGENT selects
the default harness (default claude-code), validated at startup. Removes
the temporary noopAgent stub.

* docs(agent): point the agent contract at internal/ports/agent.go
The Agent interface moved from internal/adapters/agent to internal/ports;
update the PRD's Goal and Agent Contract sections (and the SessionInfo
references) to match the code.

* Wire the session service into the daemon
daemon.Run now builds the controller-facing session service — a session
manager over the zellij runtime, a gitworktree workspace, the shared
store + LCM, and the per-session agent resolver (AO_AGENT default,
validated at startup) — and mounts it at httpd APIDeps.Sessions, so the
session REST routes are backed by a real service. startLifecycle moves
ahead of the HTTP server so both share one LCM.

* Address Greptile review: complete the live spawn path
- Spawn and Restore now install workspace-local activity hooks
(GetAgentHooks) and run the adapter's optional PreLaunch step before
launch, via a shared prepareWorkspace helper. PreLaunch is how Claude
Code records workspace trust, so its interactive "trust this folder?"
dialog can't hang the headless pane; the spawned env now also carries
AO_DATA_DIR so the installed hook commands find the store.
- claudecode and codex hook/config writes are now atomic (temp + rename)
instead of os.WriteFile, so a crash mid-write can't leave a partial
file the agent fails to parse.
- ensureWorkspaceTrusted serializes its read-modify-write under a package
mutex, so concurrent spawns to different workspaces don't drop each
other's ~/.claude.json trust entries.

* test(ports): pin MetadataKeyAgentSessionID to domain.SessionMetadata json tag
The equality between ports.MetadataKeyAgentSessionID and the json tag on
domain.SessionMetadata.AgentSessionID is a hand-maintained invariant; this
test fails loudly if either side drifts.

* refactor(adapters): use ports.MetadataKeyAgentSessionID in claudecode + codex
The native session id metadata key is defined in ports for cross-package
consumption; drop the duplicated literals in each adapter so the constant
has one home.

* test(codex): cover ensureCodexHooksFeatureEnabled TOML edge cases
The helper is a string editor over config.toml; pin its content
transformation for missing/empty files, existing [features] blocks,
the no-op case, and the legacy codex_hooks=true migration paths.

* docs(adapters): document Registry concurrency contract
Registry registration runs at daemon boot before any goroutine calls Get,
so the underlying map needs no lock; pin that contract in the doc comment
so a future change doesn't quietly introduce a race.

* style(codex): gofmt codex_test.go after constant rename
The previous commit (7c5b2a9) replaced codexAgentSessionIDMetadataKey with
ports.MetadataKeyAgentSessionID inside a map literal; the longer key threw
off gofmt's column alignment on the adjacent codexTitleMetadataKey /
codexSummaryMetadataKey lines. Caught by agent-ci's Check formatting step.

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.
* feat(backend): HTTP daemon skeleton — config, health, runfile, graceful shutdown (#10)
Phase 1a of the Go HTTP daemon lane (#10). Stands up the loopback-only
sidecar skeleton the later REST/SSE/WS/static surfaces build on:
- config: env-driven (AO_HOST/PORT/ENV/timeouts/run-file) with zero-config
defaults; binds 127.0.0.1:3001; validates and fails fast on bad input.
- httpd: chi router with the recoverer → request-id → logger → real-ip
middleware stack and /healthz + /readyz probes. Per-request timeout is
carried in config but intentionally not global — it scopes to /api/v1 in
Phase 1b so it never throttles SSE/WS/health.
- runfile: atomic PID + port handshake (running.json) for the Electron
supervisor, with a dead-PID stale check so a crashed predecessor doesn't
block startup while a live one fails fast.
- server: bind-before-publish (port conflict fails fast), graceful shutdown
on SIGINT/SIGTERM via signal.NotifyContext with a 10s hard timeout, and
run-file cleanup on exit.
Why: the daemon must be safely supervisable as a child process — the
supervisor needs a discoverable PID/port and the daemon must not leave a
half-started process or stale handshake behind. Locking the lifecycle down
now keeps the future port split a small change rather than a rewrite.
Tests cover config defaults/overrides/validation, run-file round-trip and
live/dead PID detection, health probes, full Run lifecycle, and port-conflict
fail-fast.

* refactor(backend): drop Env config field — not needed yet (#10)
Per review on #14: AO_ENV / Config.Env / IsProduction() weren't load-bearing
for Phase 1a — they only switched the slog handler. Removing them now keeps
the surface minimal; the env knob can come back later when a real consumer
needs it.
- config: remove Env field, AO_ENV parsing, and IsProduction helper.
- main: collapse newLogger to a single text-handler path.
- httpd: drop the env field from the listening log line.
- tests: drop the env assertions and AO_ENV fixture.

* docs: add backend run + config quick-start to README (#10)
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(backend): address Phase 1a review comments (#10)
- config: drop AO_HOST entirely — the daemon is loopback-only by design,
so making the bind host env-configurable was a security footgun
- config: use net.JoinHostPort in Addr() so IPv6 literals stay valid
- config: reject zero/negative AO_REQUEST_TIMEOUT and AO_SHUTDOWN_TIMEOUT
(time.ParseDuration accepts both; either would silently break the
daemon — instant request expiry / no graceful drain)
- runfile: split processAlive into unix/windows build-tagged files so
liveness detection is reliable on both platforms (Windows uses
OpenProcess; POSIX keeps signal 0)
- runfile: document os.Rename overwrite semantics (atomic on POSIX,
REPLACE_EXISTING on Windows) so the temp-then-rename pattern's
cross-platform behaviour is explicit
- httpd tests: give probe/waitForHealth clients an explicit per-request
timeout so a stalled connect can't hang the test on the outer deadline
* fix(backend): strip trailing blank line from runfile.go (#10)
gofmt CI was failing because removing the orphan processAlive doc
comment left an extra newline at EOF.
* fix(backend): cross-platform run-file replace + AO_HOST rationale (#10)
- runfile: introduce build-tagged atomicReplace — POSIX rename(2) on
Unix, MoveFileEx with MOVEFILE_REPLACE_EXISTING on Windows. The Go
runtime happens to do the Windows call internally already, but
invoking it directly makes the cross-platform contract explicit
instead of a runtime implementation detail
- runfile: tighten process_unix.go build tag from `!windows` to `unix`
so plan9/js/wasm fail to build rather than silently using a broken
signal-0 probe
- runfile: add TestWriteOverwritesExisting covering the stale run-file
replace path that none of the previous tests exercised
- config: anchor the loopback-only decision in the LoopbackHost doc so
the next contributor doesn't reintroduce AO_HOST without the security
rationale
* fix(backend): route chi access logs through slog/stderr (#10)
chi's middleware.Logger writes via stdlib log to stdout, but the
daemon's slog logger writes to stderr — so REST traffic and daemon
logs landed on different streams in different formats. Replace it
with a small slog-backed requestLogger that:
- Wraps the response writer via middleware.NewWrapResponseWriter so
status/bytes are accurate even when handlers return without an
explicit WriteHeader.
- Reads the request id off the context set by middleware.RequestID
(kept mounted just before this middleware so the id is available).
- Emits one structured Info line per request with method, path,
status, bytes, duration, and remote — same key=value shape as the
rest of the daemon, one stream for the Electron supervisor to
capture.
