Post-commit review finding: req:pitch:spelling-algorithm /
req:time:decomposition-algorithm ratified MUST-error for unregistered
algorithm ids, but derive_annotations kept the pre-ratification
derive-nothing-under-honest-profile behavior (and a test locked it).
The spec text stands; the code moves: derive_annotations returns
Result<DerivedAnnotations, PrePassError>, rejecting unregistered ids
up front — a silently-empty derivation is indistinguishable from a
legitimately empty score, and would silently disagree with an
implementation that does support the requested id. All production
callers use the default profile (.expect); the stale lock test is
rewritten as unknown_algorithm_ids_error; PrePassError re-exported.
Full gate green: fmt, clippy -D warnings, rustdoc -D warnings, 30
workspace suites, conformance scale 1 (8/8).
