# Changelog

All notable changes to RoboCo are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.3.0] - 2026-06-15

### Added

- **In-house RAG engine.** Replaced the piragi/torch retrieval stack with an
  in-house pgvector engine (asyncpg), then added **hybrid retrieval** —
  pgvector cosine fused with Postgres full-text ranking — retiring HyDE, plus
  an embed-once / concurrent-search pass that cut multi-index query latency.
- **Self-hosted LLM provider** with dynamic model discovery, so agents can run
  against a local or self-hosted model endpoint.
- **Quality gates at the source.** Developers run a fast quality gate at
  `i_am_done` and the full fast gate (including complexity) at their desk; QA
  requires a per-acceptance-criterion verdict before passing; cells run two
  developers in parallel with split-before-claim sizing.
- **Board redraft loop** — the Board can send a drafted task back to intake for
  an in-context re-draft before it starts.
- **Transcript retention** — a background sweep prunes old agent transcripts,
  with a panel-tunable retention window.
- **`tests/` type-gated under mypy** — the whole test suite now type-checks in CI.

### Fixed

- **PR-divergence respawn-loop meltdown.** Capped the PM respawn loop-gate,
  added CEO god-mode status override, a PR-conflict auto-resolver (rebase →
  close-superseded / re-merge / escalate), and sequence-ordered sibling merge;
  the dispatcher can now claim an ownerless `awaiting_pm_review` task without
  transitioning it.
- **Git robustness.** Fall back to a permitted merge method when the repo
  refuses the requested one, and retarget a PR's base to the default branch
  when the resolved base is missing on the remote.
- **RAG outage.** Migrated the live `chunks_*` tables to the in-house schema
  (offline-renderable migration), closed engine audit gaps, decoded jsonb
  metadata returned as a string by asyncpg, and kept the embedding model
  resident to stop ingest timeouts.
- **Panel.** Fixed task lifecycle (updates, merge, reassignment, copy),
  responsive grids + mobile overflow, the status dropdown duplicating the
  current status, the orchestrator-status reachability signal, and surfaced
  the CEO "Approve & Start" gate so it can't be missed.
- **Usage attribution.** Agent transcripts are attributed by an
  orchestrator-assigned session id, fixing zeroed token/cost capture for
  review-role agents.
- Composed the prompter role layer for the intake agent; aligned auditor
  channel permissions; made the app route-registration test robust to FastAPI
  0.137; cleared an xenon complexity failure and fixable test warnings.

### Security

- Documented that WebSocket authentication is REST-only and `/ws/system` is
  unauthenticated.

## [0.2.0] - 2026-06-11

### Added

- **Provider rate-limit handling.** End-to-end backpressure for LLM-provider
  429s: a Redis-backed `RateLimitStateTracker`, a spawn gate that **queues**
  (never drops) work while a provider is rate-limited, agent parking via
  `i_am_blocked(reason="rate_limited")`, and a background probe-and-resume loop
  that auto-revives parked agents when the limit lifts — escalating to the CEO
  after repeated failed probes. Surfaced live in the panel via a rate-limit
  banner.
- **Token usage & cost analytics.** Per-agent-session token capture read from
  the Claude Code transcript (`/usage/sync`), persisted to spawn-session rows
  and daily rollups, with provider-aware pricing (Anthropic models priced;
  local/Ollama models intentionally $0). Visible on the usage dashboard.
- **`/ws/system` operator WebSocket stream** with a `websocket_bridge` that
  forwards system events from the event bus to panel clients in real time — the
  rate-limit lifecycle and live token/cost usage (`USAGE_UPDATE` /
  `USAGE_SNAPSHOT`), so the dashboard's "Token Usage & Cost" panel updates over
  the socket and falls back to HTTP polling when it drops.

### Fixed

- Agent workspaces now install the project's `dev` extra (`uv sync --extra dev`)
  so spawned agents have the full `make quality` toolchain (ruff/mypy/xenon) and
  can gate their own work — closing the gap that let lint/type/complexity debt
  merge unchecked.
- Token-usage capture: the dashboard previously recorded zeros because nothing
  populated the per-session counters.
- Panel rate-limit endpoint shape (`/api/system/rate-limits` returns the
  `{ entries: [...] }` envelope the dashboard expects) and the doubled
  `/ws/ws/system` WebSocket path.
- Control-panel logo and all `/public` assets returning 500 — the panel image
  copied them without chowning to the non-root runtime user.
- Provider-aware pricing (Opus corrected to $5/$25 per 1M; non-Anthropic models
  no longer warn or mis-price).

## [0.1.0] - 2026-06-09

### Added

- Initial public release of **RoboCo** — an open-source AI agent "company": a
  virtual organization of 20 AI agents and 1 human CEO that plans, builds,
  reviews, documents, and ships software.
- Organizational hierarchy: on-demand Intake, Board (Product Owner, Head of
  Marketing, Auditor), Main PM, and Backend / Frontend / UX-UI cells.
- **Task Assistant** (the intake Prompter): a live, codebase-aware chat that
  interviews the CEO and drafts a well-formed, board-ready task — objective,
  per-cell breakdown, and acceptance criteria — then launches it into the
  lifecycle (Board review, or straight to the Main PM).
- Agent gateway (`roboco-flow`, `roboco-do`) backed by the server-side
  Choreographer; intent-verb tool surface per role.
- Task lifecycle state machine with role-based transitions and git workflow
  (PR-before-QA, CEO approval for major work).
- A2A protocol, journals, channels/notifications, kanban, and RAG (piragi +
  pgvector) knowledge base.
- Next.js control panel (`panel/`) behind a single nginx entry point.
- Multi-agent workspace management with per-project encrypted git tokens.
