The pulse-header envelope settled; the SoC die watched; item 19 closed

forgectrl pin b27398a: the SoC die joins the watched board temperatures
(/status temps soc_c and the kernel's CPU cooling state soc_throttle,
the Status tab, the per-job range line naming a throttle), a throttle
starting or ending is logged, and the supply sensor stays a raw count by
decision (its heatsink cannot be reached with a thermometer while the
machine runs). forgefirm-app pin e65cfc2 (0.1.16+git): every pulse-header
key without an applier is declared with its reason or counted as
undecided in the job log, and CLOUD.md carries one disposition table for
the whole header.

BRINGUP: the pulse-header envelope item is closed. Its durable content is
in the facts bank ("The factory's envelope, decoded": the mandatory tags,
the empty tach windows, the factory's pause and fail tiers, the
per-sensor units, the unarmed flow controller, and ForgeFIRM's answer
with its catalog proofs) and in the "Deliberately not gated" paragraph,
which names every declared family. Item 19 is now the bench-measured
head crash and rail-contact detector; the fire-watch item holds the
header's lid IR thresholds as its prior. The facts bank also records the
SoC's own thermal guard (85 C passive, 90 C critical, no heatsink on the
factory board) and the board temperatures at idle.

Catalog: cooling.gate-off checks the die field, the unthrottled state at
idle and the widened run-end line (the unit fake mirrors it). COOLING
section 9 and the SERVICES verification status describe the present.
