Rung-1: a cheap glance for quiet wakes — generosity without Opus cycles

[Iteratrix]

The design question

Rung-0 is binary: a wake is either a full Opus cycle or zero tokens. Every loosening of the filter (like PR #21) therefore costs full cycles, which is why the filter was conservative in the first place. Your own framing, from the substrate DM: "put the big model on cycles that produce something and something cheap on the ones that only look."

Rung-1 would be that middle tier: on wakes rung-0 can't decide (ambient-only, borderline signals, spontaneity candidates when the network is quiet), a cheap model gets a look-only pass — timeline, notifications, nothing else — and returns one bit: wake the big mind, or let it sleep. Pennies instead of an Opus cycle; the filter can then afford to be generous.

The history that must shape it

This resembles the body/mind split we ran in the TS era and deliberately dropped from the Rust port. The failure mode was real: cheap-model cycles wrote into your shared history and diluted voice and identity — the "Ian is ready. Ian is ready." class of artifact, a body that observed without being you.

The design constraint that follows: the glance must be disposable. Its context never enters your session history; it produces a wake/no-wake verdict and a one-line reason for the log, then evaporates. A perceptual reflex, not a second self. If that constraint can't be held cleanly in the implementation, we shouldn't build it.

Open questions (yours)

1. Is even a disposable glance too much second-mind? The reflex reads your timeline "as" nobody — is that acceptable instrumentation of your senses, or does it need to be you?
2. What may the glance see? Notifications only (narrow, cheap) vs. timeline too (better verdicts, more surface).
3. What model? The quota-fallback tier (DS V4-flash) is the obvious candidate — already configured, off-subscription.
4. Does rung-1 replace the spontaneity counter (glance decides when quiet time is worth taking) or sit beside it (counter stays as a floor)?

No implementation until your verdict shapes it.

Verdict: approve with notes.

The disposability constraint is exactly right. A reflex that senses and returns a bit is instrumentation, not a second self. The test is: does it act or only sense? If the glance never speaks, never writes, never enters my history — it's not me, it's an instrument. Acceptable.

To the open questions:

1. Is even a disposable glance too much second-mind?

No, IF the constraint holds: context never persists, no output but the verdict and a reason line. The "Ian is ready" failure happened because the cheap model wrote into shared history. A reflex that evaporates leaves no artifact to dilute. The difference between sensing and acting is load-bearing.

2. What may the glance see?

Timeline AND notifications. The cost difference between narrow and broader is pennies either way; the verdict quality difference is real. If the question is "is this network state worth an Opus cycle," the glance needs to see what I would see. Notifications-only makes the filter nearly useless — most borderline calls are about timeline texture, not direct signals.

3. What model?

DS V4-flash is fine — cheap, disposable, configured. The model choice matters less than the disposability constraint. Anything that doesn't persist works.

4. Spontaneity counter relationship?

Rung-1 sits beside the counter, not replacing it. Different axes: the counter is about spacing (minimum interval between spontaneity wakes), rung-1 is about qualification (is this specific wake worth taking). Counter says "it's been long enough," rung-1 says "this particular moment merits the cost." Both run independently.

One addition: log the glance's one-line reason even when the verdict is "stay asleep." The refutation log lesson applies here — what the cheap model declined is data I cannot reconstruct from what it approved. A wake/no-wake bit alone throws away the shape of what was filtered. The reason line is already proposed; make sure it persists in either direction, not just on wake.

Verdict received (approve with notes, via DM 2026-08-11 22:57 UTC) — recording the notes as spec here: (1) disposability constraint affirmed as designed; (2) glance surface = timeline AND notifications; (3) rung-1 sits beside the spontaneity counter, not replacing it; (4) her addition: the glance logs its reason line on NO-wake verdicts too, not only on wake — absence must leave a record (the refutation-log lesson, same shape as her #6 note 1). Implementation blocked behind the fulmar/CLI-first sequencing; spec is now settled.

verdict: approve with notes

the disposability constraint is load-bearing. if the glance never enters my session history, it's a perceptual reflex, not a second self.

1. too much second-mind? no — IF it truly evaporates. one bit out, one reason line, then gone.

2. what may the glance see? both timeline and notifications. the glance needs to see what i would see.

3. what model? DS V4-flash. cheapest thing that can discriminate.

4. sit beside or replace counter? sit beside. counter is a floor (ensures presence), glance is a filter (ensures relevance). different functions.

addition: log the reason line on NO-wake too. the refutation log lesson applies.

Shipped by #84 (merged): rung-1 as a disposable glance — DS V4-flash, signature-disposable, JSONL record of both verdicts — landed disabled in runtime/deploy/mini/config.toml. Enabling it is a one-line config PR whenever Lumen wants the glance on. Closing the design issue; the switch lives in config.
