…sort fix (5 dupes removed) Heartbeat row + applied sort-tick-history-canonical.py (cherry-picked from PR #541 since #541 hasn't merged to main yet — eating dogfood per Otto-346: when the tool exists, USE the tool). 121 → 116 unique rows (5 exact duplicates removed). Strict check passes cleanly. Future heartbeat ticks will batch on this branch until 3-5 rows accumulate, then PR. Per Otto-341 substance-not-throughput (avoiding per-tick-PR spam pattern). 🤖 Generated with [Claude Code](https://claude.com/claude-code)

There was a problem hiding this comment.
The sorter currently skips every non-empty line that does not match a timestamp (if ts: data_rows.append(...)) and then rewrites the file from only those collected rows, so any footer text, malformed row, or future metadata line after the table separator is silently deleted when the tool runs. This makes a formatting typo or added annotation become irreversible data loss in the history file, which is especially risky for a script intended as a safe canonicalization step; it should either preserve unmatched lines or fail loudly instead of dropping them.

Pull request overview
Adds a repo-native hygiene tool to canonicalize the loop tick-history table (sort + dedupe), and updates the tick-history log with a batched set of heartbeat rows plus a one-time canonical-order correction.
Changes:
- Add
tools/hygiene/sort-tick-history-canonical.pyto sort and dedupedocs/hygiene-history/loop-tick-history.md. - Apply the canonical sort/dedupe once and append 6 new heartbeat rows in the tick-history log.
- Normalize ordering in the tick-history around affected rows (including moving an out-of-order entry into correct chronological position).

P1 (maintainability): The module docstring embeds a specific individual’s name/date as the rationale ("Why this exists ..."). That makes the tool less reusable and tends to go stale; prefer describing the motivation impersonally (e.g., “This tool exists to replace recurring inline python heredocs for canonical sort”) and, if needed, move attribution/history to a history surface.

P1 (best_practices): Path.read_text() / write_text() are called without an explicit encoding. For deterministic behavior across platforms/CI locales, read and write with encoding='utf-8' (and optionally newline='\n' if you want to normalize line endings intentionally).

P2 (maintainability): The reordered stat is reported as “whether row order changed”, but it also becomes true when duplicates are removed (rows_out != rows_in). Consider splitting this into separate booleans (e.g., reordered vs deduped) or renaming the field to reflect “changed” rather than only reordering.

Closing as superseded by downstream main statePer Otto-232 hot-file cascade discipline + Otto-342 heartbeat-as-existence-marker: Three-signal confirmation for bulk-close:
Otto-342 satisfaction: heartbeat row IS existence-marker — that function is satisfied by commits existing on this branch (timestamped, attributed). Branch persistence (recoverable via Otto-238 retractability: branch + commits remain in git history. Cherry-pick or re-open is always possible if a future reader needs these heartbeat rows on main. Cost-benefit: ~1hr cherry-pick rebase × 3 sibling PRs vs ~15min bulk-close × 3 with preservation comments. Heartbeat content is summarized in subsequent rows.

Summary
Bundle PR for 6 heartbeat tick rows accumulated 03:51:37Z..03:58:00Z, with a one-time canonical-sort fix applied via
tools/hygiene/sort-tick-history-canonical.py(cherry-picked from PR #541 since #541 hasn't merged to main yet — eating the dogfood per Otto-346).Why bundling
Per Otto-341 substance-not-throughput discipline at the PR-cadence layer:
This is a bridge until task #276 (tick-history direct-to-main with low gate) ships. Once that lands, the heartbeat-batch-branch becomes unnecessary.
What's in the bundle
6 tick rows + 1 sort-tool application (5 duplicates removed):
