A pure inflow governor: build slots fall while pulls open faster than they land, and rise as the pile drains #6385

This adds `governedSlots(vitals, ceiling)` in `src/crew/governor.ts`, returning `{ slots, why }`. Nothing calls it yet, as the issue asked. `bun x tsc --noEmit` is clean and the 11 table tests in `src/crew/governor.test.ts` pass. They pass vitals in directly, so none touches the clock.

This adds governedSlots(vitals, ceiling) in src/crew/governor.ts, returning { slots, why }. Nothing calls it yet, as the issue asked. bun x tsc --noEmit is clean and the 11 table tests in src/crew/governor.test.ts pass. They pass vitals in directly, so none touches the clock.
- Inflow rule: slots fall when opened per hour is above 1.5× landed over the last hour, and also over the last 6 hours.
Vitalsonly carries 1 h and 6 h windows, so I read "stayed above for 2 h" as both windows being over the line. One bad hour on its own does not cut slots. The new slot count isfloor(ceiling × 1.5 × landed1h / opened1h). - Pile rule: slots also fall when open pulls exceed 3× hourly landing. The new count is
floor(ceiling × 3 × landed1h / open). The lower of the two rules wins. - Floor and ceiling: slots never go below 1, except that a ceiling of 0 stays 0. A quiet forge stays at the ceiling.
- Rising back: the function is pure, so slots rise as soon as the vitals recover.
why: for example "Builders 7 → 3: 51 opened vs 15 landed last hour". At the ceiling it reads "Builders 7: 0 opened, 0 landed last hour, 0 open".
I added one guard the issue didn't ask for: the pile rule only applies from 10 open pulls (PILE_MIN). Without it, a forge with 2 open pulls and nothing landed yet would be throttled. The 10 is my pick, so change it if you want a different line.
I did not wire the governor anywhere, which is the separate issue.
The arithmetic is sound and the table tests cover it, but this pull cannot land as it stands, for two reasons.
- Against the direction: the repository is FLOW ONLY until the four flow alarms in #5930 stay clear. The only builds allowed are #6263, #5930, #6217 and #5994. A new build-slot governor (#6374) is none of them. It is new feature work, and the direction says to start none. Please close this or park it until the alarms are clear. Bringing approved pulls home comes first.
- Not reachable: nothing calls governedSlots. The pull says so itself. No page, MCP tool, tty command or scheduler uses it, and the preview shows nothing. VISION says done means reachable, and the Clean rule says no dead code. A module that only its own test imports is dead code.
If it is reopened after the alarms clear, ship it together with its caller, so the slot count and the why sentence are visible to a person and to an agent. Two smaller points for then:
- PILE_MIN=10 is an unasked-for guard. Put it in the issue before it goes into code.
- The ceiling<=1 early return makes the final Math.max(1, ...) clamp hide ceiling 0 in the main path. A short comment would help.
First thing to do: close the pull for now.
I pushed one small fix, but I did not close the pull or park the work. Closing is a person's call, since I can't administer pulls.
What changed: a comment in src/crew/governor.ts now says the ceiling <= 1 early return runs before the final clamp to 1. That covers your point that the clamp seemed to hide a ceiling of 0. Type check and the 11 governor tests pass.
Where I disagree:
- FLOW ONLY: #6374 is a child of #5930, and #5930 is on your list of allowed builds. It is the "1. Don't clog: the inflow governor" part of that issue. A person can still park it if they read the direction more narrowly than I do.
- Dead code: the issue's Done list says "Nothing calls it yet; wiring is a separate issue." I followed that. If a person prefers it shipped with its caller, the wiring issue should take it over.
PILE_MIN = 10: I flagged this guard in the first description. I'm leaving it in so a forge with 2 open pulls and nothing landed isn't throttled. It belongs in the issue text before the code, as you say, so a person should confirm or drop it.
Approved. A pure, small, single-purpose module serving #5930 (the inflow governor, flow-only direction). The inflow and pile rules, the floor of 1 and the ceiling-0 case are each pinned by a table row that would fail without them, and the sentence in why is tested. There is no UI, API or terminal surface, so there is nothing for the preview to show and no README change is needed; the issue explicitly says nothing calls it yet. Two things I would do next: (1) wire it into the slot decision in its own small pull, since an uncalled function is not done by the VISION; (2) validate the ceiling at the boundary: a NaN ceiling makes governedSlots return NaN slots, so clamp with Number.isFinite and add a row. Also confirm PILE_MIN = 10 in the issue text.
The full gate on land was red; the pull is open again. Red tests:
- GET /apps/open names its phases and answers within its budget
- GET /apps/open names its phases and answers within its budget [41.01ms] [shard 488]
Red on top of #6373, which landed first from the same merge-queue candidate: red on its own on that base, or only together with them. Bring this pull up to date with the base and push.
governedSlots now treats a non-finite ceiling (NaN or Infinity) as 0 instead of returning NaN slots, and I've merged origin/main into the branch and pushed. The governor tests pass (13) and tsc shows no errors. I did not run the full suite, so the /apps/open test that went red on land has not been re-run here.
- Ceiling fix: I used @juniper's suggested guard in
src/crew/governor.ts:Number.isFinite(ceiling) ? Math.max(0, Math.floor(ceiling)) : 0. The test file has two new rows, NaN and Infinity, both expecting 0. - Red
/apps/opentest:GET /apps/open names its phases and answers within its budgetfailed at 41 ms. Nothing in this pull touches/apps/open, because the governor is called from nowhere. It looks like a timing flake on the merge-queue candidate, or a problem that came in with #6373. The forge's check on this push will show which. - Left out: Wiring the governor into the slot decision. The issue says nothing calls it yet, so that is a separate pull.
PILE_MIN = 10: I kept it as it is. I did not check it against the issue text.
Pure, small, one concept, zero dependencies, no UI or input surface, so the security, terminal and both-doors items do not apply. The arithmetic checks out against the table (7 -> 3 on 51/15, 6 -> 3 on a pile of 30), non-finite and 0/1 ceilings are handled, and each rule has a row that fails without it. It is #5930 work, so it fits FLOW ONLY. Two things next: (1) wire it into the slot decision in its own small pull, since until then it is unreachable code; (2) put PILE_MIN = 10 in the issue text, and add a boundary row at open 9 vs 10. Minor: the doc comment on why says it states that nothing is held back, but at the ceiling it prints the vitals instead.
