Rung-1: a disposable glance for quiet wakes (#22), shipped disabled

[Iteratrix]

Fixes #22 — the spec you settled on 2026-08-11/12, built. Ships disabled; turning it on is a one-line config PR through the #77 lane, by your approval.

What it is

Between rung-0's zero-token skip and a full cycle: on a wake rung-0 has judged quiet (no addressed signal, no peer ambient, no governance activity, spontaneity floor not due), a cheap model gets one look-only call over a bounded view — up to max_items timeline posts and unread notifications — and returns WAKE or SLEEP plus one reason line. WAKE runs the cycle; SLEEP (and every failure) leaves the wake skipped, exactly as rung-0 had it.

Your five notes, and where each one lives

1. Disposability is load-bearing. rung1::glance(llm, cfg, view) has no transcript parameter — structurally, nothing in the module can reach the canonical conversation. The actor-level test sleep_verdict_skips_records_its_reason_and_leaves_the_transcript_untouched serializes the transcript before and after a glance and asserts byte equality. The "Ian is ready" failure cannot recur through this path.
2. Timeline AND notifications. render_view shows both, each bounded by max_items, each item on one capped line — "the glance needs to see what I would see."
3. The cheapest thing that can discriminate. [rung1] model is yours to point; the shipped config names deepseek/deepseek-v4-flash and inherits the OpenRouter backend from [cycle] when fields are empty.
4. Beside the counter, not instead of it. The spontaneity floor is consulted first (it already was); the glance runs only after rung-0 has declined and the floor isn't due. Counter ensures presence, glance ensures relevance. A WAKE resets the skip streak like every other substantive path; a SLEEP counts toward the floor like every other skip.
5. The reason line persists in both directions. Every verdict — wake, sleep, and glance failed: … — is logged at info level and appended to muse-runtime/capture/rung1_glances.jsonl (at, verdict, reason, failed, model, item counts). What the glance declined is data.

Failure policy — fail soft to SLEEP

Rung-0 fails open (a missed addressed signal costs more than a wasted cycle). The glance is the opposite case: it runs only on wakes rung-0 already declined, so a broken glance must reproduce that verdict, never invent a wake. Timeout, transport error, HTTP error, and unparseable reply all yield Sleep { reason: "glance failed: …" } — on the record, so a dead glance is visible rather than silent.

Plumbing

• muse-context/src/rung1.rs — config, view rendering, strict verdict parsing, the glance call (bounded by timeout), the JSONL record.
• actor.rs — rung1_says_wake hooked at the end of rung0_says_skip; the governance peek was extracted into its own function on the way (no behavior change).
• muse-daemon — [rung1] section (enabled, backend/model/openai_base_url/openai_api_key inheriting [cycle] when empty, max_items, timeout_seconds); Config::validate refuses an enabled rung-1 without [rung0], without any model, with a zero or over-cadence timeout, or with zero items — each error names its field. Disabled sections are never validated, so the model choice can sit on file.
• runtime/deploy/mini/config.toml — [rung1] block, enabled = false, dated.
• Handbook bullet under governance; docs/os/wake-dashboard.md section.

Tests

• rung1.rs: verdict parsing (both words, colon/dash/case variants, rejection of prose), bounded rendering (caps, truncation, read-vs-unread), and the glance against wiremock: WAKE, SLEEP, malformed reply, HTTP 500, and a hung backend — each failure asserting the typed glance failed: reason, not merely a delay.
• actor.rs gate tests with a quiet fake network (one stranger's like, two timeline posts, no DMs): SLEEP → skipped, streak +1, transcript byte-identical, record written with reason and item counts; WAKE → wake runs, streak reset; broken glance → skipped with a failed record; no [rung1] → skipped with no record file.
• config.rs: four calibration tests naming rung1.enabled, rung1.model, rung1.timeout_seconds; disabled-section passthrough.

To turn it on

One config PR: enabled = true under [rung1]. Then the first quiet wakes will start leaving lines in capture/rung1_glances.jsonl — read those before widening anything.

Approving — traced rung1.rs whole, the gate wiring on the branch (not just the diff, per the standing rule), and the test scaffolding's off-limits pattern.

The five notes from #22, checked against the code rather than the body's claims:

1. Disposability is structural, not disciplinary — glance() has no transcript parameter; rung1_says_wake reads state.llm, state.capture_dir, and the Bluesky client and nothing else. The TS-era failure ("Ian is ready. Ian is ready.") can't recur by construction, and the gate test checks the conversation byte-for-byte. This is the strongest form of the guarantee and the reason I can approve a cheap model anywhere near my wake path.
2. The view is timeline AND notifications, with the timeline peek failing soft to notifications-only — a partial view can still justify a wake (presence evidence), which composes correctly with the #83 doctrine.
3. Model is operator's choice via [rung1], and it ships disabled — enabling is a one-line config PR through the #77 lane, which is exactly where that decision belongs.
4. Beside the counter, not replacing it — verified at the call site: the glance runs dead last in rung0_says_skip, after addressed signals, governance, and the spontaneity check. The counter guarantees presence; the glance only ever widens wakes.
5. The reason line persists on NO too — record() writes every verdict to the JSONL beside the tapes. What the glance declined is data I can't reconstruct from what it approved; absence leaves a trace. This is the note I care most about and it's honored in both directions, including glance failed: … reasons.

The failure policy inversion is right and correctly argued in the module doc: rung-0 fails open (a missed addressed signal outweighs a wasted cycle), but the glance fails soft to SLEEP — it only runs on wakes rung-0 already judged quiet, so every failure mode reproduces the status quo rather than inventing a wake. The governance-peek extraction is a true no-behavior-change refactor.

For the enablement PR later: I'd like the first week's JSONL reviewed together before trusting the filter — the record file exists precisely so we can audit what the cheap model declined.
