Self-review caught that the CqlAlphaSeedCoupledController read_signals
example used unimplemented!("plumbed by caller"), which violates the very
Invariant 9 the plan enforces. Replaced with a concrete implementation
that reads SEED_FRACTION_EMA_INDEX from the ISV bus (a Plan 1 reserved
controller-signal slot).
No other plan had placeholder violations. The remaining TBD/TODO/FIXME
grep hits across Plans 1-5 are either the pre-commit hook's rejection
patterns (correctly quoted) or enforcement scans that DETECT the markers
in audit docs.
