Model backend rows gain a harness column (claude | pi). A pi-harness row runs
the agent through the pi coding agent instead of the claude binary — pi speaks
the OpenAI Completions API natively, so a bare vLLM/llama.cpp/Ollama endpoint
needs no LiteLLM/claude-code-router translation proxy, and the loop is far
lighter for slow local token throughput. The Claude subscription and existing
claude-harness backends are untouched.
Parity comes from generated per-agent artifacts under ~/.handler-pi (outside
the repo tree, so the clean-tree gate never trips): models.json + settings.json
render the row as a pi provider pinned as the default model; a bundled bridge
extension (pi_bridge.ts) adapts pi's events to the exact stdin/stdout contract
of `python -m handler.hooks` — the Stop/completion gate re-prompts pi with
blockers via a follow-up message, git push runs the test/build/approval gates
and denies on failure, questions defer through an ask_operator tool into the
normal answer/resume flow, and memory recall is injected at session start. The
memory tools are registered natively (pi has no MCP), shelling to a new
`python -m handler.mcpserver --call <tool>` seam that reuses the MCP server's
implementations. Skills reuse the same ~/.claude/skills sync (pi implements the
same SKILL.md standard) plus the repo's committed .claude/skills.
Sessions are single JSONL files pre-assigned via --session, so cross-worker
resume archives/materializes exactly like claude's; the prompt travels on stdin
(pi has no -- separator). The supervisor normalizes pi's event stream on the
fly: assistant message_end feeds last_output, the final agent_end becomes the
run result. The whole chain was validated live against pi 0.84.1 with a stub
OpenAI endpoint: memory injection, push-gate denial (including the protected-
branch approval gate), stop-gate block loop, and ask_operator pause all ran
end to end through the real hooks and DB.
Also: harness selector in the dashboard Models form, pi baked into the control
image (NodeSource 22 for pi's node >= 22.19 floor), PI_BIN override, docs in
docs/local-models.md, fake_pi fixture + 12 tests (361 total green).

Git servers (forge_hosts) become full credential owners:
- an encrypted forge token (Fernet, HANDLER_SECRET_KEY) stored per server and
never returned by the API (has_token flag only); used automatically by every
project on that host and addressable as db:host:<hostname> — the reserved
db: credential scheme is now live
- a per-server ed25519 SSH deploy key: generated server-side, public half
shown in the dashboard to paste into the forge, private half encrypted at
rest and materialized 0600 only in the control container (GIT_SSH_COMMAND /
core.sshCommand)
Project registration gets a git-server mode: pick a registered server, type
owner/name, and the API derives the remote (ssh when the server has a deploy
key, https otherwise), computes root_dir under PROJECTS_ROOT, and enqueues a
new 'sync' command the worker executes (clone, or ff-only pull). Spawn always
pulls first, so runs start from the remote's latest state; POST /projects/:p/sync
and 'handler sync' re-pull on demand.
Schedules: recurring agent spawns (prefix, prompt, interval, role). The worker
fires due schedules as ordinary queued spawn commands with timestamped agent
names, so runs are fresh stateless agents and appear in the Activity audit
trail; missed intervals collapse into one catch-up run.
Dashboard: Git Servers pane shows the SSH public key (copy button) and takes a
write-only token; Repositories gains the server-first add form and a Pull now
button; new Schedules pane. Rebuilt static export. Also restores the missing
frontend/lib (api client + format helpers) the components import.

Make credentials/hosts, projects, agents, and approvals manageable from the
dashboard. The API and control layer are separate containers, so the API can't
run control actions directly (no git/tmux/claude, doesn't own the tmux
sessions). Instead the API enqueues a command and a worker in the control
container executes it and writes the result back.
Data model (migration 0003):
- `commands` queue/audit table; `forge_hosts` registry; `approvals` gains a
nullable approver id + `actor` so operator verdicts are first-class.
Control worker:
- `control/worker.py` claims commands and dispatches to the existing control
functions (spawn/kill/resume/record_approval/write_skills/poller.sweep),
plus a periodic CI sweep. New `handler worker` CLI subcommand; it becomes the
control image's default command (subsumes `poll-ci --watch`).
API:
- `require_admin` gate + `ADMIN_TOKEN`; project GET/PATCH/DELETE; agent
spawn/kill/delete; resume now enqueues (fixes a cross-container bug where the
API tried to send tmux keys to a session in the control container); new
approvals/commands/hosts routes; forge-init and poll-ci enqueue endpoints.
Credentials/hosts:
- host->token-env lookup consults the `forge_hosts` registry first (built-in
map is the fallback); `resolve()` refactored to a scheme dispatch reserving
`db:` for a future encrypted store. Web input restricts credential_ref to
env:/file:/db: (cmd: stays CLI-only — it would run arbitrary commands).
Dashboard:
- New tabs for projects, agents (spawn/kill with live command-status polling),
approvals, hosts, and an activity/audit view; shared context is now writable.
Tests: +33 (queue atomicity, worker dispatch, CRUD, hosts, admin gating,
cmd: rejection, host-aware credentials, and an API->queue->worker->spawn
end-to-end). README gains a Web management section.

Add a no-build, same-origin web frontend so an operator can open a URL,
see every agent's state, and answer a paused question with no terminal
(Phase 3 DoD). The UI is a client of the existing API — no endpoint,
schema, or auth change — so the 106 existing tests pass unchanged.
- app.py serves the bundled UI from / and /static, gated on UI_ENABLED
(default on); optional CORS_ORIGINS (default empty => no middleware)
for hosting the UI on a separate origin. Dedicated /static prefix +
explicit / route so API routes are never shadowed. Zero new runtime
deps (StaticFiles/CORSMiddleware ship with Starlette).
- static/: vanilla fetch + plain CSS + vendored alpine.min.js (v3.14.8,
no CDN). Token captured once into localStorage; all API values render
via x-text (never x-html) to block agent-authored markup injection.
Project switcher, agent list, checkmark panel, paginated log, shared
feed, and Answer / Answer & Resume. Polling scoped to the selected
agent to avoid an N+1 over the fleet.
- config.py: ui_enabled, cors_origins (+ cors_origin_list); documented
in .env.example.
- tests/test_api_ui.py: serving, unauthenticated shell, non-shadowing
401 regression, CORS toggle, UI_ENABLED=false. 114 tests, ruff clean.
The static assets ship in the wheel by default (they live inside the
packaged src/handler tree) — no force-include needed.
Phase 2 configures forge for the agents (operator only sets a credential_ref +
optional version pin) and lets them drive a junior→senior→deploy workflow:
- Credential resolution/injection (control/credentials.py): credential_ref pointers
(env:/file:/cmd:) resolved only at spawn, injected as FORGE_TOKEN + host var, with a
forge-host-scoped git credential helper reading the token from env (never on disk / in
the DB). Resolution is a fail-fast spawn gate.
- Role-based forge skills committed into the managed repo (control/skills_gen.py,
`handler forge-init`): forge-junior/senior/deploy + a workflow overview.
- Hard approval gate (hooks/gate.py, approvals table, migration 0002): merge/deploy —
and direct pushes to protected branches — are denied unless a DIFFERENT agent has an
`approved` record for the branch, pinned to the reviewed commit (approved_sha). Senior
records verdicts via `handler approve`/`reject`.
- forge/git seams (control/forge.py, control/gitops.py) matching the Phase 1 seam pattern.
- CI status poller (control/poller.py, `handler poll-ci [--watch]`) backfilling
ci_status/ci_checked_at via `forge ci list`.
- Fix: migrations/env.py commits explicitly after run_migrations — pysqlite on Py 3.12+
was rolling back the final migration's DDL + alembic_version stamp (latent in Phase 1).
Reviewed via a separate code-reviewer pass; gate-bypass and credential-scoping findings
addressed. 106 tests, ruff clean, verified end-to-end against real git + migrations.
Implements the Phase 1 MVP from the README: a stateless control layer + HTTP
API over a centralized database, with hook-enforced test/push gates.
- DB layer: SQLAlchemy Core, one schema rendering both Postgres (BIGSERIAL /
TIMESTAMPTZ / JSONB) and SQLite (INTEGER PK / TEXT / JSON) via portable types;
native ON CONFLICT DO UPDATE checkmark upsert on both dialects.
- Alembic dual-dialect migrations (render_as_batch for SQLite); tests run a real
`alembic upgrade head`.
- FastAPI: projects/agents/checkmark/log/answer/resume + shared log/context
routes, single global bearer token, higher-trust token gating shared-context
writes, project isolation on every route.
- Hooks (`python -m handler.hooks <event>`): Stop test gate (block on red),
PreToolUse AskUserQuestion defer + `git push` gate (tests then throwaway
build), Notification generic webhook (no-op without WEBHOOK_URL). Identity via
env injected at spawn; verify is the mock seam.
- Control CLI: spawn/list/attach/kill, hard `.mise.toml [tasks.test]` gate,
generated per-agent settings.json, identity + DATABASE_URL injected via tmux;
tmux is the mock seam.
- 45 tests (SQLite), ruff clean. Live claude/tmux/mise spawning deferred behind
the mocked seams.
