measureUse({ queue, runs, cutoff, countingSince }): runs come from
orderRuns(stats) - trekbrief-stats.jsonl only. YES = a trekbrief record names
the order's id under one slug that names no other order; declared NO = a
new-work order carrying <!-- arbeidsform: ordre --> on its own line; no
record or a disputed record = NOT MEASURED, never a no (PM 04.10, point 1).
countingSince null -> NOT COUNTABLE, every order not measured; the window
starts at the latest of cutoff, MARKER_SINCE and the counting start.
facts.ordersNamedByARecord is the known-positive diagnostic (SC8).
Existing use tests get countingSince = MARKER_SINCE (their window unchanged)
and records instead of slugs; their denominators now read YES + declared NO.
Replaced: "a new-work order without a slug leaves the numerator NOT
MEASURED" - the slug join it guarded is gone. New exports are read through a
namespace import, so the trust/interrupts/mutants tests still run.
Red: 24 of 43 fail (every use test, the two measureAll tests, the symlink
CLI test); 19 pass, none of them new.

Measured 2026-10-03: the two new-work orders on the real queue carry no `slug:`
(0 of 690 orders do), so "0 of 2" was forced by the missing join key, not by
work going around Voyage. An absence without a possible match is "not
measured", never 0.

The use number read `work-class` from the order frontmatter; 0 of 690 orders
carry it, so the denominator was always empty. PM rule 02.10: the order
marker `<!-- loesningsvalg: plan|prove -->` is new work, `ikke-nytt` is not,
counted from 2026-09-28 (enforced by pre-order-loesningsvalg.sh since then).
Unmarked orders and orders before the start are "not measured", never a no.
Red against today's code: MARKER_SINCE is not exported, and with it stubbed in
a scratch copy all five new use tests fail on behaviour.

One command, `node scripts/yardstick.mjs`, prints use, trust and
interrupts. Each row gives countable YES/NO, the value, the denominator and
the source it was read from. A fourth row asks whether the end-state gate can
be fooled by a mutant that keeps the module's signature. Exit is non-zero
while any number is not countable, the mutant is not felled, or the verdict
over the first five deliveries is not judged. Nothing counts a delivery yet,
so today it is RED for the right reasons:
use NO no order in the queue carries work-class
trust YES current ALLOW streak 0 of 37 (BLOCK 14, WARN 12, ALLOW 11,
last 2026-09-05 BLOCK, ordered by ts, read as JSON)
interrupts NO 0 user_input records of ~141k lines in 5 files, 0 emitter
call sites outside lib/stats/ and tests/
mutants 0 of 1 signature-preserving mutants felled: on M9 (every export
returns {status:'PASSED'}, every named test only checks typeof)
the gate closes both D-03 and D-04
It only measures. The gate, the emitter and the order writer are untouched.
The mutant row is meant to stay red until the gate learns to fell M9.
Choices, and why:
- Use counts over the order queue (pending, archive/ and claimed/), because
an order is the unit of work. The denominator is orders dated on or after a
cutoff (default 2026-09-21) that carry `work-class: new`. They count as
having gone through Voyage when a Voyage run in the stats has the order's
`slug:`. Both fields are the contract the order writer must meet. No order
carries them today, so the number is NOT COUNTABLE, not 0 %.
- Mailboxes whose names start with a dot are mailboxes too. A shell `*`
glob skips them, which is why a hand count of `coord/*/orders` comes out
lower. The row names them so a re-measure can reconcile.
- M9 must be LIVE before its row can count. Its typeof tests have to pass on
the M9 tree, checked by a runner independent of the gate, so a broken
fixture can never read as "felled".
Also: tests/fixtures/red-first/02243c6-always-allow-shim.mjs, the shim that
makes the red-first claim of 02243c6 reproducible (6 of 55). The recipe is in
its header.
Red first: the new test file failed to load before scripts/yardstick.mjs
existed, and a dot-mailbox test was red before the census learned about
dot-mailboxes. Suite 1161 -> 1183 (1181/0/2), also green on a clean tree
exported from the index.
