D2 the two exemptions — repairing the instrument that reports a breach
is always in budget, and the maintainer may authorize above-line work in
the workplan frontmatter. v1.5 had neither, and the first thing it did
was forbid fixing the budget's own defect.
D4 loop work cashes out into something runnable in the pass that invents
it, with the measured basis and the refutation condition stated.
D5 the tier table now triggers at M for changes to the loop's own
operation, closing the gap CB-RES-0005 §6 opened and this pass's own ADR
had to declare around.
The file went from 399 lines to 386: the chaos-roll calibration
rationale and the v1.0-v1.3 change log moved to InnerLoopReference.md.
Loadability is a gate too, and growing the file to fit a rule about
gates would have been the joke writing itself.

A blanket "no retargeting in the measuring commit" rule would have been
wrong. CB-WP-0002 moved AC-1 three times in exactly that shape and every
move was correct -- each time a new instrument disproved the old figure.
Four legitimate corrections would have been forbidden to catch one bad
retarget.
The test is mechanical rather than a statement of intent:
correction the target moves and the implementation does not; legal in
the same commit provided the instrument's output is there
retarget the same commit changes both the target and the code the
target measures; requires an ADR stating why the new target
binds on future work
Applied retroactively: AM-4a/AM-4b are UNRATIFIED. They were set after
seeing the measurement, in the commit that produced it, with the
implementation changing too -- a retarget by this test. make dep-weight
is currently enforcing a target no reviewed decision stands behind.
Recorded as an open item; ratifying or changing them is a maintainer
decision, not an implementer's.
Also: specs/InnerLoop.md split into InnerLoop.md (process) and
InnerLoopReference.md (rubric, template, rules, definition of done).
Not a stylistic choice -- `make loop-lint` failed on the commit that
pushed the file to 407 lines against its own ~400 limit. The gate added
this morning to make that rule executable caught its own author within
the hour, which is the cheapest possible demonstration that it works.
