# hyperhive — claude entry point

Hey claude. This is your starting page. The detailed docs live in
[`docs/`](docs/) and are written for humans + you both — read them
when you need depth on a subsystem. This file is the index +
scratchpad.

- High-level project intro: **[README.md](README.md)**.
- Open work + backlog: **[TODO.md](TODO.md)**.

## Reading paths

Pick the doc that matches your task. None depend on the others —
read them à la carte.

- **"What does the dashboard look like?"** →
  [`docs/web-ui.md`](docs/web-ui.md).
- **"How does claude get its prompt and what tools does it have?"** →
  [`docs/turn-loop.md`](docs/turn-loop.md).
- **"How do config changes flow from manager to operator to
  container?"** → [`docs/approvals.md`](docs/approvals.md).
- **"What state survives destroy / purge / restart?"** →
  [`docs/persistence.md`](docs/persistence.md).
- **"Naming, commit style, wire protocol, the `data-async`
  pattern."** → [`docs/conventions.md`](docs/conventions.md).
- **"Why does the nspawn flag look like that?"** →
  [`docs/gotchas.md`](docs/gotchas.md).

## Quick reminders

- **Commit before test.** Stage and commit when work *looks*
  ready, then run validation. Failures get a follow-up commit
  rather than an amend.
- **Commit messages: short, lowercase, no `Co-Authored-By`
  trailer.** Imperative mood.
- **`rebuild` is the reconcile verb.** Anything that changes
  per-container state on the host should be re-applied there so
  the dashboard's `↻ R3BU1LD` is sufficient to recover.
- **Identity = socket.** No auth tokens — the socket path
  identifies the principal.
- **Actions are factored** between admin socket and dashboard via
  `actions.rs` and `dashboard.rs::lifecycle_action`, so the two
  surfaces never drift.

## Scratchpad

In-flight or recent context that hasn't earned a section yet.
Prune freely.

- Loop session 2026-05-15: shipped state badge, /cancel + /compact,
  tombstones, multi-select ask_operator, broker + events vacuum.
- After loop session 2026-05-15: docs split into `docs/` (this
  page slimmed to index + scratchpad). Cleanups landed: vacuum
  host-side, `lifecycle_action` helper, `api_state` split.
- Next likely focus: telemetry/charts (still queued from earlier
  triage) + server-side state badge.
