shard(tick): 1003Z — PR #3402 + #3403 merged; substantive N+1 discipline phrasing correction

[AceHack]

Summary

• PR shard(tick): 0950Z — PR #3400 merged with 2 post-merge threads; substantive rule-citation acknowledgment #3402 + shard(tick): 0955Z — 3 post-merge threads on #3401; self-shard-PR off-by-one lesson #3403 merged
• 3 post-merge threads on shard(tick): 0955Z — 3 post-merge threads on #3401; self-shard-PR off-by-one lesson #3403: Codex + Copilot caught my 0955Z N+1 mitigation had reversed-flow phrasing
• Corrected: PR does NOT exist at shard write-time; flow is write → commit → push → gh pr create
• N+1 count is still empirically correct; explanation now accurate

Pull request overview

Adds a new hygiene-history tick entry for 2026-05-15 1003Z documenting that PRs #3402 and #3403 have merged, and correcting the previously inverted explanation of the N+1 in-flight counting discipline (PR creation happens after commit/push, not before).

Changes:

• Create tick log 1003Z.md describing the merges of PR #3402/#3403 and post-merge thread outcomes.
• Correct the narrative explanation of N+1 discipline to match the actual workflow sequence (write → commit → push → gh pr create).
