Pull request overview
This PR adds a hygiene tool to canonicalize (sort + dedupe) the loop tick-history table, and appends the third bundled batch of 5 heartbeat rows (2026-04-26T04:04:41Z..04:07:58Z) capturing the “scale to N agents” substrate observation.
Changes:
- Add
tools/hygiene/sort-tick-history-canonical.pyto sort/dedupedocs/hygiene-history/loop-tick-history.md. - Update
docs/hygiene-history/loop-tick-history.mdwith the bundle-3 tick rows and related row re-ordering.

P1: File I/O uses Path.read_text() / write_text() without an explicit encoding. That makes the tool’s behavior platform-dependent (e.g., Windows code pages) and can cause non-deterministic rewrites. Please specify a fixed encoding (typically UTF-8) for both read and write.
| Usage: | ||
| python3 tools/hygiene/sort-tick-history-canonical.py [--dry-run] | ||
|
|
||
| Default: writes changes back to the file. | ||
| --dry-run: prints what would change; does not modify the file. | ||

P2: The docstring says --dry-run “prints what would change”, but the implementation only prints a summary line. Either adjust the wording to match behavior, or print a minimal diff/changed-row count so the flag delivers on the description.

P1: This tool file includes direct name attribution (e.g., “Why this exists (Aaron …)”) in a current-state code surface. Repo rule is to use role-refs outside the closed set of history/research surfaces; please replace the name with a role-ref (e.g., “the human maintainer”) or move the attribution/quote into an allowed history surface and keep the tool docstring role-ref-only.
Ref: docs/AGENT-BEST-PRACTICES.md Operational standing rules “No name attribution in code, docs, or skills …” (lines 284-349).

P0: sort_canonical currently drops every non-empty line in the data section that doesn’t match get_timestamp(). If the tick-history ever contains a malformed row, a note line, or any future non-row content after the separator, this tool will silently delete it when rewriting the file.
Safer approach: either (a) preserve non-row lines in place (and keep them tied to their original positions), or (b) treat any non-empty non-row line as an error and abort with a diagnostic listing the offending lines.

| if not line.strip(): | |

| f" data line {sep_idx + 2 + original_index}: {line}" | |
| for original_index, line in invalid_lines | |
| ) | |

Any non-empty line in the table body that doesn’t match get_timestamp is skipped here, and the rewritten file is built only from unique_rows, so malformed/extended rows are silently deleted on write. In this log, that means a single unexpected row format (for example a future timestamp variant or an annotation line added during incident handling) can permanently erase audit history when this tool is run; the sorter should either preserve unmatched lines or fail fast.

There was a problem hiding this comment.
The CLI help says --file is relative to repo root, but Path(args.file) resolves against the current working directory. Running this script from tools/hygiene/ with defaults fails with file not found, which makes automation and local usage brittle unless callers always cd to the repo root first.

Summary
Third heartbeat-batch bundle (5 rows). Captures substantive Aaron exchange on scaling commit-as-existence-proof to N agents — long-term answer is per-writer-instance files (Otto-240 design); task #276 direct-to-main is bridge, not scale-answer.
What's in the bundle
Substantive content
Aaron's reframe: "direct-to-main becomes higher priority. is only a short term solution unless it can scale to multiple atunomous agents who all want to commit to exist"
