ops(tick-history): autonomous-loop tick 2026-04-30T05:31:00Z — slice-13 merged + session-arc closure

[AceHack]

Summary

Append closing session-arc tick row to loop-tick-history.md (320 → 321). Covers PR #892 merge (slice 13 — tools/git/push-with-retry) plus the full review-cycle on #892 (5 real findings from Codex P2 + Copilot P1/P2, all resolved in one round-trip commit).

Three observations seeded:

1. eslint-disable-next-line directive placement — rationale must precede directive; comments between directive and target line break the suppression.
2. spawnSync failure classification (4-case: status / ENOENT → 127 / signal / other) is reusable substrate for future TS ports.
3. Automated reviewer findings compound usefully when batched — 5 findings round-tripped clean through new tsc-tools gate.

Session arc total

8 PRs landed: #885 (slice 12) + #888 (B-0106 row) + #886 (tick) + #887 (tsc fix) + #889 (tick) + #890 (B-0106 implementation) + #891 (closeout) + #892 (slice 13).

After-merge: 34 ports total, Bucket B at 8 files remaining.

Test plan

• Row matches 6-column schema (col-5 = e9dc894).
• CI gate (lint markdownlint + tick-history order + new lint-tsc-tools).
