# 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).

## [0.6.0] - 2026-06-17

### Added

- **Inbound PR review — the org reviews, and can take over, pull requests it didn't open.** A new read-only `pr_reviewer` role (a 22nd agent, its own first-class image and spawn manifest, migration 037) discovers inbound PRs, reviews the diff adversarially, and posts a single complete change-request as a real GitHub review on the PR itself — no agent-to-agent chatter. It covers external / fork PRs, gated by a configurable author allowlist, and — behind a second flag — internal org-repo PRs opened outside the agent task-flow (the org's own in-flight integration PRs are skipped, since a live task already owns their branch and they pass QA + PM review). Re-review is driven by the PR's head commit (an unchanged PR is skipped, new commits open a fresh review), and polling is repo-aware so a monorepo is no longer reviewed several times over. External-PR review is enabled by default in the shipped compose (with human-confirm on); internal-PR review is off by default. Both are flippable from the panel.
- **CEO decision queue + supersede for reviewed PRs.** Completed reviews surface in a PR-review queue in the panel — in-flight reviews are shown too, linking to the PR, so it never goes dark. From there the CEO can dismiss a review, or **supersede** the PR: the system cuts a roboco-owned branch off the contributor's commits and opens a Main-PM coordination task to finish and harden the work to our standards on that branch, open our own PR, and — once that replacement actually merges — close and link the contributor's PR. We never push to a contributor's fork.
- **Feature-flags panel.** A Settings → Feature Flags card toggles env-gated subsystems (external / internal PR review, web research, the strategy engine, pitch provisioning, RAG auto-update, transcript pruning) from the panel instead of hand-editing environment variables. A toggle persists in the existing settings store and takes effect on the next backend restart; an unset flag falls back to its environment / config default, and secrets (API keys, tokens) are never surfaced to the client.
- **Required-cells decomposition gate.** When a coordination task names the cells that must deliver it, the Main PM can no longer go idle having silently dropped one — `i_am_idle` is rejected until every named cell has a subtask, and the Main-PM prompt now insists on honoring explicitly-named cells rather than quietly dropping them. Inert until the marker is set, so existing flows are unaffected.

### Changed

- **Run from pre-built registry images.** A standalone registry compose runs the full stack — including every per-agent image, now extended to the Secretary and the PR-reviewer — from published images rather than a local build. Both deploy paths, the registry knobs, and measured idle / under-load resource usage are documented.
- **Documentation, for humans and agents.** The how-to guide is now a structured, multi-chapter walkthrough under `docs/how-to/` with a new business-workflow chapter (charter → Cockpit → Secretary, and the research / strategy / PR-review toggles); the published reference docs (README, usage, deployment, CLAUDE) were refreshed against the current code, with a CI guard that keeps documentation prose single-line. Agents also get richer in-context guidance: new RAG role docs for the Prompter, Secretary, and PR-reviewer, the 0.4.0 company layer (goals / research / strategy / provisioning) documented for them, and a refreshed guardrails surface.

### Fixed

- **The PR-reviewer no longer respawns in a loop.** Without a spawn manifest the reviewer had no flow verbs, so it could never claim its review and was respawned over and over (burning tokens); it now ships a role-scoped manifest and reliably claims its work. The supersede close-on-land path was also hardened — the contributor PR is retired only once our replacement PR has actually merged, not merely when the umbrella task completed.
- **A CEO-rejected coordination root no longer deadlocks.** A product-linked coordination task the CEO sends back to needs-revision is re-dispatched to its owning PM (and the readiness gate now accepts a PM on a coordination root in that state), instead of sitting unowned forever because the developer dispatcher skipped it.
- **Panel UI standardization + usability pass.** A panel-wide pass plus targeted fixes: the Settings grid layout, the Journals and Kanban scroll regions, the agent-list item, the Projects table, kanban cards whose text overflowed, the PR-review queue's empty state, and the Secretary chat composer buttons.

### Internal

- DB-backed and httpx-mocked test coverage for the inbound-PR read and lifecycle paths (ingest / dedup / classify / claim / complete / supersede); a cyclomatic-complexity refactor of the git PR-creation and lifecycle-validation code to clear the xenon gate; and the cell-PM / main-PM role docs corrected to the real `delegate` signature and cross-linked to each other.

## [0.5.0] - 2026-06-16

### Added

- **Acceptance-criteria & decomposition guardrails.** Every task's acceptance criteria now carry stable per-criterion ids, and each decomposed subtask records which parent criteria it is responsible for (`covers_parent_criteria`). Two gates build on that linkage: a PM can no longer go idle leaving a parent criterion with no subtask responsible for it (the decomposition floor), and a parent can no longer complete / submit up / escalate to the CEO unless every one of its criteria traces to a child that passed QA on it (the roll-up gate). PMs see live coverage in their briefings (`parent_ac_coverage`, `unclaimed_parent_acs`) after each `delegate`. Safe-by-construction: every gate stays inert until a PM starts declaring coverage, so existing decompositions are never blocked. (Migration 036.)
- **Per-dev sequenced code queues.** A cell PM now delegates each developer its full queue of code subtasks up front instead of one task at a time. Both cell developers build in parallel, and each works its own queue one task at a time, in order — enforced by a per-lane dispatch barrier, with leaf PRs still merged in sequence into the shared cell branch. The old "two code subtasks per parent" ceiling is removed; the 12-subtask hard cap and a same-title duplicate guard remain.
- **Unified Business page.** The Company Goals, Secretary, and Pitches pages are consolidated into one tabbed **Business** page (Goals / Secretary / Pitches), modeled on the Knowledge Base page with deep-linkable `?tab=` URLs. A single sidebar entry replaces four.

### Changed

- **Company Goals, Secretary, and Pitches brought to the panel's standards.** Skeleton loading and offline/error states, structured fields instead of raw JSON dumps, required-note confirmation dialogs for pitch and directive decisions, and markdown rendering in the Secretary chat.

### Removed

- **The standalone Cockpit page.** Its data duplicated the Dashboard and Metrics; its one unique element — the strategy-engine "needs your attention" signals — was relocated to the Dashboard, served by a new lightweight `GET /api/cockpit/signals` endpoint. The `/cockpit`, `/company-goals`, `/secretary`, and `/pitches` panel routes are all retired (404); the Goals, Secretary, and Pitches views now live under `/business?tab=…`.

### Fixed

- **Agent MCP/SDK servers no longer stall on spawn.** They launch with `uv run --no-sync`, so a workspace clone whose lockfile has drifted from the baked image no longer triggers a multi-minute dependency re-sync that left the gateway tools stuck "pending" and the developer respawning in a loop.
- **`open_pr` no longer fails on a missing base branch.** `create_pr` auto-creates and pushes the PR's base branch off the default branch when it is not yet on the remote, instead of returning a GitHub 422.
- **Admin status overrides restore task ownership.** Forcing a blocked task back to pending / in_progress now restores its pre-block assignee, so an escalated code task no longer re-enters the pool still owned by a PM and is dispatched to that PM as if it were a developer.
- **A developer can idle past its own queued work.** With per-dev queues, a dev whose current leaf has moved to QA now idles cleanly while its later queue items wait their turn (the orchestrator respawns it when the lane clears), instead of looping on the idle guard or claiming the next leaf out of order.
- **26 verified panel UI bugs** across the dashboard, kanban, task detail, and API layer: consistent priority labels and badge sizing, dark-mode coverage, kanban drag-and-drop that prompts for the required audit note, auto-scroll in the message and mentor-chat views, corrected WebSocket reconnect counting, `PATCH` (not `PUT`) for partial task updates, working "Activate Task" and "Start Revision" actions for backlog and needs-revision tasks (no more dead-end menus), the previously-dead "New / Generate Report" buttons, a duplicate agent id, a "0h ago" timestamp, and more.

### Internal

- Verb-table generation no longer emits tables for the driver-based roles (prompter, secretary), whose real tools live in their SDK drivers rather than the gateway verb surface; and the `_briefing_for` typed stub was aligned with its implementation so the composed choreographer type-checks under full mypy.

## [0.4.0] - 2026-06-15

### Added

- **Business Goals — the company charter.** A single CEO-owned charter (north star, prioritized objectives, constraints, operating policy) injected compactly into every agent's briefing so all work is goal-aware. `GET /api/company-goals` (any agent) / `PUT` (CEO-only), with a panel editor.
- **Web research for the Board and PMs.** Pluggable `web_search` / `web_fetch` exposed through a `roboco-search` MCP server backed by `/api/research/*`, with Tavily / Brave / Exa adapters and a graceful no-op when no provider is configured. The provider key stays server-side — agent containers never make the external request themselves — and a per-agent daily quota (Redis, fail-open) bounds cost.
- **Pitch → approve → provision.** The Board proposes a product (a "pitch"); on CEO approval the system provisions a GitHub repo per target cell, registers a Project for each (and a Product when multi-cell), and seeds one Main-PM delivery task — reusing the existing Product / coordination-task machinery. Default-off: with no provisioning token configured, approval is refused and nothing is created.
- **Autonomous strategy engine (dormant).** An optional second engine that watches the company against its standing goals and surfaces drift, idle, and long-stranded blocked work to the CEO (notify-only — it never spends, builds, or auto-approves). Off by default; the delivery lifecycle is unchanged.
- **The Secretary — the CEO's chief-of-staff.** A live conversational agent (its own role, distinct from the Prompter) the CEO chats with in the panel. It acts only under the CEO's command: it reads company state and relays dictated messages directly, but high-impact actions — editing the charter, starting / cancelling / overriding tasks, approving a pitch, announcements — are queued and run only after the CEO's explicit confirmation (the gate list). Its authority is HMAC-scoped to the secretary role and routed through the existing enforcement, never a parallel permission model.
- **The Cockpit.** A read-only `/cockpit` view answering "is the business winning, what's happening, what needs me" — the charter, delivery counts, 30-day spend vs the budget cap, pending pitches, and the strategy engine's signals. Honestly stamped `basis: proxy` (a proxy until real launches).

All of these are additive and opt-in or default-off — an unconfigured deployment behaves exactly as before.

## [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.
