# Changelog

All notable changes to handler are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/); versions are the `v*` tags
the image workflows publish (plus `latest` from every push to `main`).

## [Unreleased]

### Added

- **Tappable fleet stat cards** in the mobile app: Running / Waiting / Done now open a
  full agent list pre-filtered to that bucket (same grouping as the counts), showing
  every agent row the API knows — including agents that haven't dropped a checkmark
  yet — with status badges, a live last-output line for running agents, and
  tap-through to the agent detail screen (back returns to the list).

### Added

- **Activity screen in the mobile app** (Settings → Manage → Activity): the
  control-command queue with status filters, per-row worker attribution
  (`on <worker>` / `unclaimed`), expandable result/error text, a Sweep CI action, and
  a 5s auto-refresh — the screen that answers "why is my login/spawn/sync stuck" from
  the phone.

### Fixed

- **Untrusted-workspace wedge on headless runs.** Phase 4's tmux-path deletion also
  removed the only call to `claude_config.ensure_onboarded`, so agent working dirs —
  every fresh worktree — were never pre-trusted in `~/.claude.json` and headless
  `claude -p` runs wedged or refused on the trust dialog with nobody at a TTY. Spawn
  and resume now re-seed onboarding + per-directory trust before every launch (resume
  included, so a cross-worker resume landing in a container that has never seen the
  working dir is covered). 2 regression tests.

### Added — mobile app feature parity

The iOS app (`app/`) catches up with everything the backend and web dashboard gained
since its last release:

- **Model backend picker on spawn**: the spawn form now offers the registered model
  backends (`/claude/models`) next to the Claude subscription, matching the web
  dashboard's per-spawn dropdown; the agent detail meta card shows which backend an
  agent is pinned to, plus its supervising worker.
- **Headless run event stream**: a new Events tab on the agent detail screen polls the
  cursor-paged `/agents/{name}/events` endpoint and renders the stream-json events live —
  assistant text, tool-call badges, run results with turns/cost, worker notices, raw
  lines.
- **Schedules tab**: list, create (interval, role, model backend, prompt), pause/resume,
  and delete recurring agent spawns across all projects.
- **Memory tab**: the agent-memory note graph (`/memory/graph`) with kind filters and
  expandable notes showing body, tags, and links — plus note authoring and deletion.
- **The full management surface** (Settings → Manage): model backends (CRUD incl.
  write-only API keys and the claude/pi harness pick), skills (incl.
  install-from-prompt), MCP connectors, plugins, permission overrides, repository
  registration (git-server + manual modes, mise-init), forge hosts (encrypted tokens,
  generated deploy keys), branch approvals, shared context, and the worker's
  `claude /login` flow — the phone no longer needs a laptop nearby.
- **User accounts on mobile**: the connect screen gains email sign-in against
  `/auth/login` (session token stored like the legacy env token), first-run admin
  setup, forgot-password, and an API-token fallback (auto-selected for servers
  predating accounts); Settings gains an Account screen (identity, change password,
  sign out with server-side revocation) and Manage gains the admin Users screen
  (invite with shareable links, promote/disable, reset links, delete).

### Added — built-in operator skills, pre-installed on every deployment

Eight skills now ship inside Handler (`handler.builtin_skills`) and are seeded into
the managed skill store on API startup, so every fresh install — and every existing
deployment on upgrade — starts with the judgment layer the hard gates can't enforce:

- `handler-quiet-output` — work through tool calls, not prose: the transcript is not
  the deliverable. A minimized `NOTES.md` ledger records what happened and how,
  problems go to memory, status goes to the checkpoint, and questions go through the
  question tool (push notification + answer prompt in the web/mobile apps) — never
  typed into the transcript.
- `handler-gate-recovery` — respond to a blocked completion/push gate by fixing the
  real failure; never delete/skip tests, weaken the mise `test` task, or `--no-verify`.
- `handler-testing` — every behavior change lands with a test that fails without it;
  keep suites fast and deterministic.
- `handler-checkpoints` — checkpoints written for a phone-sized glance; questions only
  for operator-only decisions, with a recommended default.
- `handler-memory` — search before starting; save gotchas/decisions/runbooks, not
  narration or secrets.
- `handler-mise-tasks` — `mise run test` is the verification contract; never narrow it
  to get green.
- `handler-scheduled-runs` — the read-state-file → one increment → overwrite-state-file
  continuity pattern for recurring runs.
- `handler-secrets` — injected credentials stay out of logs, commits, PRs, and memory.

Seeding is idempotent by name: operator edits/disables survive every upgrade; deleting
a built-in restores it (as shipped) on the next API start. 6 new tests (406 total).

### Added — user accounts: email sign-in, invites, resets, per-user separation

- **Email + password accounts** replace "know the API key" for humans. First run shows
  a setup form and the **first account created is the admin**; every later account is
  **invited by an admin** through a one-shot set-password link. Passwords are scrypt
  (stdlib, self-describing hashes); sessions are opaque bearer tokens stored only as
  SHA-256 with a configurable TTL.
- **Password reset by email** (`POST /auth/forgot` → short-lived link, silent about
  account existence) via plain SMTP (`SMTP_*` settings). **Email is optional**: with
  SMTP unset, invite/reset links are shown to the admin in the dashboard to hand over
  out-of-band. Spending a link revokes the account's existing sessions.
- **Per-user separation of projects, skills, and tools.** Projects, skills, MCP
  connectors, plugins, and model backends gain an owner; users see **shared + their
  own** (foreign resources 404 — existence isn't leaked), owners operate their own
  projects end-to-end without admin, shared (unowned) rows stay admin-managed and
  visible to all. Launches materialize only the project owner's skills/connectors, and
  private model backends can't be picked for someone else's spawns or schedules.
  Deleting a user reassigns their resources to shared; admins can reassign owners.
- **Users page** in the dashboard (admin-only): invite, admin/disable toggles, reset
  links, delete. Sign-in page gains first-run setup, forgot-password, and a raw
  API-token fallback; `/reset` is the public landing page for invite/reset links.
- **Admin safety rails**: the last active admin can't be demoted/disabled/deleted; no
  self-deletion. `AUTH_TOKEN`/`ADMIN_TOKEN`/`SHARED_CONTEXT_WRITE_TOKEN` keep their
  exact historical semantics for scripts/CI and break-glass.
- 24 new tests (auth flows + separation matrix; 397 total).

### Database (user accounts)

- Migration **`0016_user_accounts`**: new `users`, `auth_sessions`, `auth_tokens`
  tables plus a nullable `owner_user_id` on `projects`, `claude_skills`,
  `claude_connectors`, `claude_plugins`, `claude_models`. Purely additive; existing
  rows have no owner (= shared) so an upgraded deployment behaves exactly as before
  until accounts are created.

### Deployment notes (user accounts rollout)

1. Apply migrations as usual (the API container runs them on start).
2. Optionally set `SMTP_HOST`/`SMTP_PORT`/`SMTP_USERNAME`/`SMTP_PASSWORD`/`SMTP_FROM`
   (+ `SMTP_STARTTLS`/`SMTP_SSL`) and `PUBLIC_BASE_URL` for emailed links; without
   them, invite/reset links appear in the dashboard instead.
3. Open the dashboard and create the first account — it becomes the admin. Existing
   `AUTH_TOKEN`-based scripts keep working unchanged; the token can be rotated or
   dropped once accounts exist (keep one as break-glass if you like).
4. New TTL knobs (optional): `SESSION_TTL_DAYS=30`, `RESET_TOKEN_TTL_HOURS=2`,
   `INVITE_TOKEN_TTL_HOURS=168`.

### Added — the pi harness for local models ([#29](https://github.com/0xWheatyz/handler/pull/29))

- **`harness` on model backends** (`claude` | `pi`, default `claude`). A backend row can
  now run its agents through the lightweight [pi coding agent](https://github.com/badlogic/pi-mono)
  instead of the `claude` binary. pi speaks the OpenAI Completions API natively, so a
  bare local endpoint (vLLM, llama.cpp, Ollama) works **without** a LiteLLM /
  claude-code-router translation proxy — and the loop is far lighter for slow local
  token throughput. Selectable in the dashboard's Claude → Models form and via
  `POST /claude/models`.
- **Full gate parity on pi** via a bundled bridge extension (`pi_bridge.ts`, generated
  into a per-agent `PI_CODING_AGENT_DIR` under `~/.handler-pi/`, outside the repo tree).
  All gate logic stays in the same tested Python hooks:
  - Stop/completion gate (tests green + committed + pushed) re-prompts pi with blockers;
  - `git push` runs the test → image-build → protected-branch approval chain and denies
    on failure; `forge merge` / `mise run deploy` hit the approval gate;
  - questions defer through a new `ask_operator` tool into the normal answer/resume flow;
  - memory recall injects at session start; `memory_search/get/save/link` are registered
    as native pi tools (pi has no MCP) through `python -m handler.mcpserver --call`.
- **Web tools for agents**: `web_search` and `web_fetch` (`handler.webtool`), registered
  on pi-harness agents. Fetch is provider-free (HTML stripped to readable text,
  size-capped). Search resolves `SEARXNG_URL` → `BRAVE_SEARCH_API_KEY` → a zero-config
  DuckDuckGo fallback.
- **Full built-in tool surface on pi**: `read`, `write`, `edit`, `bash` plus `grep`,
  `find`, `ls` (off by default in stock pi) — 14 tools total including the handler set.
- **Skills + prompts on pi**: pi discovers the same web-managed `~/.claude/skills` sync
  and the repo's committed `.claude/skills` (forge role skills); handler conventions are
  appended to pi's system prompt; `AGENTS.md` / `CLAUDE.md` are read natively.
- **Cross-worker resume for pi sessions**: single-JSONL transcripts pre-assigned by
  handler, archived/materialized through the existing `session_archives` flow.
- `PI_BIN` binary override; `SEARXNG_URL` / `BRAVE_SEARCH_API_KEY` settings; a `fake_pi`
  test binary and 22 new tests (370 total).

### Changed

- **Control image**: Node bumped from NodeSource 20 to 22 (pi requires ≥ 22.19; Claude
  Code needs ≥ 18, unaffected) and `@earendil-works/pi-coding-agent` is baked in
  alongside the Claude Code CLI.
- `control.models` refactored: `resolve_model()` returns the row + decrypted key and
  `harness_of()` / `claude_env()` split harness selection from env building.
  `resolve_model_env()` keeps its signature (claude rows unchanged; pi rows return `{}`).
- Dashboard Models form gained the harness selector and a `pi harness` badge; docs
  (`docs/local-models.md`, README) describe both harnesses.

### Database

- Migration **`0015_model_harness`**: adds `claude_models.harness`
  (`NOT NULL DEFAULT 'claude'`). Purely additive — every existing backend row keeps its
  current behavior. Applied automatically by the API container on start (`RUN_MIGRATIONS`
  stays `false` on control, as before).

### Deployment notes (for this release's rollout)

Merging to `main` publishes both images (`docker.yml` → `ghcr.io/0xwheatyz/handler`,
`docker-control.yml` → `ghcr.io/0xwheatyz/handler/control`). To roll out:

1. **Pull both images and restart API before control** (compose already orders this):
   the API applies `0015_model_harness` on boot; the control worker only needs the new
   column to exist when a pi backend is first selected.
2. **The control image must be the new build** before spawning any pi-harness agent —
   it carries the `pi` binary and Node 22. Older control containers refuse cleanly
   (launch fails loudly, no silent fallback to the subscription).
3. **No env changes required.** Optional: `SEARXNG_URL` or `BRAVE_SEARCH_API_KEY` on the
   control container for a real `web_search` provider (unset = DuckDuckGo fallback);
   `PI_BIN` only if pi lives off PATH.
4. **Existing agents are untouched**: subscription and claude-harness agents launch
   exactly as before; running agents and their resumes are unaffected by the migration.
5. **Rollback**: reverting the images is safe — the `harness` column is ignored by old
   code. Only agents already pinned to a pi backend would fail to resume until the new
   control image returns (`alembic downgrade` would drop the column; not needed for an
   image-level rollback).
6. **Volume/layout invariants unchanged**: same `PROJECTS_ROOT`, same
   `HANDLER_SECRET_KEY` everywhere, no new shared filesystem. pi state lives under the
   worker's `$HOME` (`~/.handler-pi/`) and sessions ride the existing DB archive flow.

### Verification

- 370 tests green (SQLite, real `alembic upgrade head` per test), including the new
  `fake_pi` runner suite and mocked web-tool provider tests.
- The bridge was validated live against pi 0.84.1 with a stub OpenAI endpoint: memory
  injection, push-gate denial (including protected-branch approval), the stop-gate
  block loop, `ask_operator` pause/resume, and the 14-tool surface all ran end to end
  through the real hooks and database.

## Earlier work (pre-changelog)

Phases 1–2 plus the web dashboard, headless runner, credential store, schedules, model
backends, skill install-from-prompt, and the agent memory layer predate this changelog;
see `docs/PLAN.md` and the merged PR history for their details.
