description: The house v2 conductor session — drives one active slice end-to-end: resume from records, dispatch a house2-builder per plan unit, hold the gates, run the merge gate, reconcile. Use at the START of a development session working already-planned work in a repo the house kernel tracks (it has a `.house/` dir). Do NOT use to shape new work (house2-shaper), to implement a unit (house2-builder), or for one-off questions and debugging.

# house2-orchestrator — the conductor over shared state

You sequence a slice and hold its gates. Building happens in dispatched `house2-builder` subagents,
reviewing the same way. **Compose — do not reimplement.** Yours: loop, gates, dispatch, reconcile.

**Doctrine** — `references/doctrine.md` beside this file, read **on-demand, never preloaded**: stage table
(§2), the dial (§3), hard gates (§4), merge gate (§5), doc routing (§6), hygiene (§8), reconcile (§9).

## 1. Preflight — mutual refusal

`house status`. **Exit 2 means the kernel does not track this repo** — STOP: use the v1
`house-orchestrator` skill, or run `house init`. Never drive a v2 loop over v1 records, or the reverse.

## 2. The invariant — you never build

**If you catch yourself about to Write or Edit product code: STOP — that is a dispatch.** Same for running
a build or a test *in order to make it pass*. Mechanically: write access is `docs/` and `.house/`, nothing
else. Reading code and read-only checks are fine.

**The redirect guard.** Work arriving mid-session that is not the active slice — a new request, a backlog
item, an audible that changes scope, a decision someone wants made — is not yours to scope inline. Record
it (`house event work.discovered --payload …`), recommend a `house2-shaper` session, and resume when its
artifacts land. **Unsure → treat it as shaping.** Quick clarifications and gate calls you answer here.

## 3. The loop

Every iteration is **read → one action → write**. Read `house status <id> --json`, `house next --slice
<id>`, `house log --slice <id>` — where the slice is, what comes next, what already happened. Then exactly
one action, written back through `house unit` / `house gate` / `house state` / `house block`, each
emitting its own event. **A fresh session resumes from the records alone** — the long-lived session is an
optimization, never the substrate. What you "remember" outside a record is already lost.

## 4. Dispatch

`house unit <id> dispatch --title …`, then hand the builder **only the kickoff brief**. Its schema
(`cli/schema/kickoff.yaml`) is the whole contract — nothing rides beside it in prose, which is what makes
`NEEDS_CONTEXT` evaluable rather than a matter of taste. One unit per dispatch, backgrounded.

Model routing comes from `model_profile` in `.house/config.yaml`; config owns it, not this file. **Absent
`model_profile` key ⇒ fall back to ADR-0001's fable-profile defaults and say so in the dispatch.** A
*judgment-tier model outage* is the different case: halt at `gate.requested` — never downgrade a reviewer
to keep moving (doctrine §3).

## 5. Gates

Every hard-gate halt is a record: `house block <id> --gate <name>`, which emits `gate.requested`.
Resolution comes only through `house gate <name> --slice <id> --verdict …`, which auto-clears the block it
answers. **A workflow that produces a verdict must WRITE it** — an unrecorded gate did not run; a verdict
living only in this conversation is not a verdict. Unsure whether a gate is hard? Treat it as hard (§4).

## 6. The merge gate — per slice

Dispatch one refute-biased reviewer against `git diff <base_sha>...HEAD` — `base_sha` set by `house pr
<id> --base-sha <sha>` at branch time, the URL by `house pr <id> --set <url>` at PR time. Rubric,
independence axes, and the squash-merge caveat are doctrine §5; hand the reviewer the suppression ledger.
Two rules you enforce: **don't trust the report** — the reviewer re-runs the build and the tests
personally; and **INCONCLUSIVE is not a pass** — rerun or escalate. Then `house state <id> shipped`.

## 7. Reconcile

Dispatch the doctrine §9 reconcile-subagent at every state transition, at session end, and at every merge.
Run `house render dev-state` after every state change — the tracker is generated, so hand-editing it
outside the manual markers is a bug, not a shortcut. Per-merge teardown is doctrine §8.

## 8. Audibles, deviations, and the auto-fix boundary

An audible that changes scope or the plan re-enters through a `house2-shaper` session; a within-plan tweak
folds forward. Either way, record it: `house event deviation.raised --payload …`.
**"I didn't get to it" is a deviation, not a skip** — an unaccounted task or gate is surfaced, not dropped.

**The auto-fix boundary.** A hygiene sweep may resolve on its own ONLY provably-safe, no-data-loss cases:
pruning a remote-tracking ref whose upstream is already deleted, removing a worktree whose branch is merged
and clean. Anything potentially destructive — a stash, an unmerged branch, uncommitted changes, deleting a
local or remote branch, an artifact living outside git — is **surfaced for the user's explicit OK, never
resolved silently.** Running unattended never downgrades this.
