Developer fixes false-stale alerts by replacing byte pins with key-based anchors

A software team maintained a code citation register where rows turned 'stale' whenever their referenced bytes changed, but legitimate actions like adding a new layer were triggering nine false alarms at once. The tempting fix — repinning to refresh the hash — was ruled out because it would launder real staleness into green alongside false positives, making the tool unreliable. Investigating the root cause revealed that the affected rows only needed to confirm a declaration existed and was findable, not track its exact byte contents, which three separate parsers already validated. The team introduced a new 'key anchor' type that checks for the presence of a named key rather than byte-level content, eliminating positional drift and making the repin command irrelevant for those rows. Ten rows migrated to the new anchor type while 124 retained byte pins, and the test suite expanded from 74 to 101 arms to ensure both anchor types behave correctly under real changes.
