tick-history: 16:19Z — Otto-347 recursive-application + 2nd-agent recovery (#625) + Otto-275-FOREVER landing

[AceHack]

Summary

Tick-history row covering ~24 min after the 15:55Z manufactured-patience diagnosis row (#623, merged). Aaron's two prompts ('did you double check' + 'check with another cli') caught Otto-347 violations + drove 2nd-agent recovery of 2 lost tick rows (~5.9KB substantive content) on #618→#620.

Coverage

• Otto-275-FOREVER memory landed (live-lock 9th pattern)
• Otto-347 reinforcement (operational gate added)
• 2nd-agent recovery: tick-history: recovery — restore 13:38:50Z + 13:52:34Z rows lost in #618→#620 supersession #625 merged, 13:38Z + 13:52Z rows restored
• Comprehensive 8-PR closure audit: 7 EQUIVALENT + 1 PARTIAL LOSS recovered
• Drain-log tick-history: 15:55Z manufactured-patience live-lock diagnosis + tasks #290 #291 done #622 written + landed via docs(pr-preservation): drain-log for #622 (closed-not-merged, superseded by #623) #624
• Copilot fact-error caught + resolved on tick-history: 15:55Z clean-reapply (supersedes #622) — manufactured-patience live-lock + #290 #291 done #623 (MEMORY.md path-ambiguity)

Test plan

• sort-tick-history-canonical.py: in canonical order
• check-tick-history-order.sh: OK 156 rows non-decreasing
• markdownlint: pass (after fixing pipe-in-code-span violations on first draft — Otto-275-FOREVER recursion in action)

Pull request overview

Adds a new autonomous-loop tick-history entry (16:19Z) documenting Otto-347 supersession verification failures, subsequent 2nd-agent audit/recovery of lost rows, and the landing of the Otto-275-FOREVER memory.

Changes:

• Appends the 2026-04-26T16:19:00Z tick row to the loop tick-history table.
• Captures the narrative/operational notes around 2nd-agent verification and recovery work tied to recent PR supersessions.

Re: both Copilot threads on this merged row (PRRT_kwDOSF9kNM59rEoH + PRRT_kwDOSF9kNM59rEoG):

Thread 1 (line-count 601→602): same one-line drift pattern as the previous fix on #623. Tick-history rows are immutable on main per discipline; future rows touching MEMORY.md will use ~600 lines qualitative phrasing per the suggestion to avoid exact-count truth-drift.

Thread 2 (operational-gate bug — substantive catch): Copilot is correct that the git show ... | grep '^+' shape I documented in the Otto-347 reinforcement has bugs (includes +++ b/<file> patch headers as false positives; ignores deletions / context). Updated the user-scope Otto-347 memory file with a corrected operational-gate using git diff against merge-base + final-state comparison via git show $SHA:$FILE. More critically: clarified that the 2nd-agent dispatch IS the actual gate per Aaron's original framing ("would be good to ask another cli"); same-agent diff is helper-prep for the 2nd-agent audit, not substitute. Empirically validated this session: same-agent diff said #618↔#620 "equivalent"; 2nd-agent caught PARTIAL LOSS (~5.9KB).

Recursive Otto-275-FOREVER: the rule I just landed to fix discipline-application had its own discipline-application bug. Fix landed in the corrective layer.
