hygiene(#268+): pr-preservation drain-log for #424 (4-parent cascade)#453
Conversation
Otto-268 follow-on: drain-log for the **maximum-multi-parent cascade** observed in this drain wave — #424 was a follow-up to FOUR parent PRs simultaneously (#405 empty-cone + #411 GITHUB_TOKEN header + #413 grammar + #415 Otto-279 policy reply). Composes-vs-serializes tradeoff favored compose: one commit + one merge gate addressed all four parents. Per Otto-250 training-signal discipline. Pattern observations: 1. Maximum-multi-parent cascade: 4 parents in one follow-up. Composes when findings are independent + small. #423 had 2 parents; #424 doubled to 4. 2. fail-YELLOW vs fail-RED on structurally-normal empty-input cases (empty cone, zero qualifying findings, no diff to lint) — over- blocking risk when fail-RED on empty-input. CI-design candidate: every audit script should explicitly classify "empty-input" behavior at design time. 3. GitHub canonical-example form (`Authorization: token $GITHUB_TOKEN`) vs accepted-also (`Authorization: Bearer $GITHUB_TOKEN`); prefer canonical for reader friction reduction. 4. Otto-279 surface-class reply remains stamp-uniform across the corpus regardless of multi-parent grouping; the multi-parent grouping doesn't change per-finding response.

Pull request overview
Adds a PR-preservation drain log for PR #424, capturing the post-merge review findings and resolutions across a 4-parent cascade (#405, #411, #413, #415) to preserve Otto-250 training-signal records.
Changes:
- Add
docs/pr-preservation/424-drain-log.mddocumenting the four parent-grouped threads, outcomes, and pattern observations. - Record final resolution metadata (resolution SHA, merge SHA) for the drain follow-up.

P1: This drain log says it’s a “full record” per Otto-250, but the thread sections don’t preserve the verbatim reviewer comment + reply or the usual thread metadata (e.g., thread ID, and often file:line / resolution commit per thread). docs/pr-preservation/_patterns.md:9-13 explicitly states per-PR logs preserve verbatim reviewer text, and logs like docs/pr-preservation/108-drain-log.md show the expected shape. Please expand each thread to include the verbatim original comment and reply (and include thread IDs where available).

Nit: “Thread count at drain” is describing the parent-cascade shape rather than the numeric thread count. Since this drain has 4 threads (1.1–4.1), consider rewording to something like “Thread count at drain: 4 threads across 4 parents …” for consistency with other drain logs (e.g., #422).

Minor grammar: “note that Bearer is also accepted preserved” reads like a dropped word; suggest rewording so the sentence is grammatical (e.g., include “is” / “was”).
