callLogs.ts (996 lines, frozen-baselined) mixes pure log-formatting /
sanitization helpers with DB CRUD, disk-artifact, and rotation logic. Extract
the ten pure, DB-free helpers verbatim into a leaf, leaving all stateful code
in the host:
- callLogs/format.ts (129) asRecord, toNumber, toStringOrNull, truncateText,
parseInlineError, normalizeDetailState, sanitizeErrorForLog,
toStoredErrorSummary, protectPipelinePayloads, buildRequestSummary
Host callLogs.ts: 996 -> 885. The stateful generateLogId (mutates logIdCounter)
stays in the host. These helpers were all module-internal, so the public API is
unchanged (10 exported functions). Bodies moved byte-identical; the host's now
unused 'sanitizePII' import (only referenced inside the moved bodies) moved to
the leaf; prettier wrapped buildRequestSummary's signature across lines once the
'export' prefix pushed it past 100 cols (token-identical).
Behavior-preserving: 46 existing call-log consumer tests stay green
(call-log-cap 14, pagination 4, file-rotation 5, log-retention 5, startup 1,
oom 2, trim-sql 2, db-settings-maintenance 13); new
tests/unit/calllogs-format-split.test.ts (26 assertions) characterizes the pure
helpers + guards the 10-function public API.
