Summary

basou board measure and basou board record (experimental) now compare a board with its previous record.

• The previous record: for a declaration named board.yaml, the last by name of the files in the records/ beside it named as a ULID with .json. Other files are passed over, and a declaration of another name reads no records.
• diff in the measurement:
  • Lists each value that moved, by where it is (repos["../basou"].commits), a number with its change, marked method_changed when its section's method changed.
  • Lists the methods that changed, and the values there only now or only then.
  • Entries are told apart by what names them (repos by path, open tracks by id, not_found by where). Unacknowledged and gone components are compared as sets. Values are compared with their keys sorted.
  • Not compared: the clock, the freshness, the axis and its not_found entries, measured_with, and the effort's daily rows.
  • The diff is left out of the digest, and the text summary puts it first.
• Components: the section holds the kinds that changed since the previous record, and counts as gone a component only it found (methods.components is 2).
• Axis:
  • The section judges trigger (e), a built-in section's method that changed.
  • It takes the last review from the last record with an axis review, dated in the effort section's time zone (UTC when none can be named), before the declaration's seed (methods.axis is 2).
• A record that cannot be read is never taken as no record: the diff, what only it found and the triggers it bears on are null or not judged, with a reason under not_found. A component the declaration registers that was not found still fires (a).
• basou board record:
  • Says what moved right after where the record is, in the measurement, the cells and the observations, also under diff with --json.
  • Lists what the measurement recorded could not measure, also under not_found with --json.
  • The record itself does not hold the diff.
  • What a previous record holds is shown with its control characters escaped.

Verification

• CI steps run locally with exit codes, after the last change: pnpm -r build, pnpm typecheck, pnpm -r test:coverage, pnpm test:scripts, pnpm lint (the existing warnings only), pnpm lint:lang, pnpm lint:paths, and pnpm audit --prod: all 0. Board tests pass under TZ=UTC, Asia/Tokyo and America/New_York.
• On a real workspace, against a record written by the previous build:
  • The diff shows components and axis methods 1 -> 2, and (e) fires.
  • The last review comes from the record.
  • Recording again and measuring at once shows nothing moved.
  • After the fixes, no axis entry reaches the diff.
  • Nothing new under .basou/.
• Mutations: 61, all caught. These cover the reader, the diff, components, the axis, measure, record, the CLI and the escaping. The first 49 were applied again on the final code.
• Review: one round of convergent review (review only).
  • The reviewer read a record written by the previous build with this one.
  • Seven findings, all fixed: the axis's not_found entries reaching the diff; (a) not firing on a registered component gone when the previous record cannot be read; the wording on when complete turns false; the summary calling measured components unmeasured; where record shows its diff and why there is none; key order in compared values; and two missing tests.
