The trace specification owns the declared identifier vocabulary and the
comparison result echoes those identifiers verbatim into raw_trace[].event_id,
matched_variant and diagnostic event_ids. The result module restated the shared
IDENTIFIER_PATTERN by hand with a 64-character cap, so a specification with a
longer identifier validated and then its own comparison result failed to parse:
compareProcessTraces threw a raw ZodError at the caller instead of returning a
comparison.
Export the identifier schema from the specification as the single owner and
reuse it in the evaluation module, removing the capped copy. IDENTIFIER_PATTERN
has no length bound and every other consumer uses it unbounded, so the
duplicate was the outlier. Removing the bound rather than adding one keeps the
advertised trace_spec input contract unchanged; identifiers of 64 characters or
fewer behave exactly as before.
Verified with 48 process tests, 24 boundary CLI/MCP trace tests, check:fast and
verify:test-discovery on macOS arm64. The regression test failed with the
ZodError before the change and passes after it.
