hygiene(#268): pr-preservation drain-log for #219 (Amara 3rd-ferry absorb)#442
Conversation
…sorb) Otto-268 backfill: drain-log for PR #219 covering 12 threads (7 FIX + 3 STALE-RESOLVED-BY-REALITY + 2 OTTO-279 SURFACE-CLASS). Per Otto-250 training-signal discipline. Pattern observations capture four load-bearing patterns: 1. External-source verifiability as a research-doc reproducibility discipline (URLs + arXiv IDs + DOIs are one-line-each but convert "grounded somewhere" into "reviewers can verify"). 2. Inline-code-span line-wrap is the most-recurring formatting bug in this drain wave; pre-commit-lint candidate. 3. Otto-279 history-surface uniformity matured into a one-paragraph stamp reply for aurora-archive Attribution sections. 4. Phase-numbering / count-vs-surface-list cardinality findings recur across docs; future doc-lint candidate.

Copilot P2: prior summary 'sixth phase ... five phases total' read as a contradiction. Reword to 'sixth phase ... after five existing phases' so the drain-log doesn't record an impossible phase count.

…iated shape divergence (#467) * hygiene(_patterns.md): document Otto-250-canonical vs Otto-268-abbreviated drain-log shape divergence Multiple post-merge reviewer threads on the Otto-268-wave drain-logs (#437-#465) flagged that the abbreviated inline shape doesn't match the canonical Otto-250 multi-section format used in older drain-logs (#108, #247, etc.). The findings are correct: the shapes ARE different, and the abbreviated shape compresses verbatim reviewer/reply text into short prose. Documenting both shapes here in `_patterns.md` as a known divergence + three maintainer-decision options: (a) Rewrite — high churn, highest faithfulness. (b) Accept divergence — document both as valid. (c) Hybrid — canonical for substantive logs (math / crypto / algorithms / ADRs); abbreviated for low-substance. Until maintainer decides, drain-runners writing future logs default to canonical; existing Otto-268-wave logs stay abbreviated with this known-divergence pointer. This is the right place for the documentation per the synthesis- over-history surface-class declaration: `_patterns.md` reflects current corpus state including known shape divergences, separate from the per-log records. Composes with the per-PR drain-log threads currently flagging the shape-conformance gap on #437/#441/#442/#444/#445/#446/#447/#449/ #460/#461/#464/#466 — those threads can now reply with a one-line pointer to this section instead of repeating the maintainer- decision-pending framing. * hygiene(#467): fix 4 Copilot findings on shape-divergence section Four Copilot catches converging on the same root cause: the shape-divergence section was citing drain-log PR-numbers (#437-#465) when readers will look for #437-drain-log.md etc. and not find them — drain-log FILE numbers reference the PRESERVED PR (e.g., #421/#422/#423), not the drain-log PR itself. The current file corpus ends at #434. Fixes: - :374 + :394 — drop the misleading "#437-#465" PR-range citation; cite the actual in-repo abbreviated-shape examples (#421/#422/#423) by file path; drop the unsupported "22+" numeric estimate in favour of "the 2026-04-25 backfill wave". - :380 — abbreviated template snippet now matches what the in-repo abbreviated logs actually use: `Finding:` bullet included, `Thread ID:` and `:LINE` placeholders dropped (those are canonical-shape fields, not abbreviated-shape). Reader can now copy/paste the template accurately. - :388 — soften the "Substance is preserved" overstatement to the objective claim: key metadata (reviewer/severity/outcome/ commit) is preserved; verbatim original-comment + verbatim reply text are NOT preserved; multi-section structure + file:line locator + Thread ID are also typically omitted. The fixes are themselves Class A (count-vs-list cardinality on "#437-#465" range) + truth-drift on a freshly-landed doc — appropriate self-application of the discipline this section documents.

Append-only row per Otto-229 discipline: drained 17 unresolved threads across 8 of my own drain-log PRs (initial 13 + 4 cascade findings on this drain wave's fixes). Documents the 'drain-log self-correction at scale' pattern — Codex/Copilot reviews caught Class A/B pattern instances inside the same doc-lint BACKLOG row that promotes them to lint candidates (appropriate self-application). PRs drained: #449 / #442 / #441 / #464 / #456 / #465 / #467 / #444. Auto-merge SQUASH armed across the queue. Cron f38fa487 minutely fire verified live throughout the tick.

Summary
Otto-268 backfill: drain-log for PR #219 (aurora absorb of Amara's 3rd courier ferry — decision-proxy + technical review), covering 12 threads.
Per Otto-250 (PR review comments + responses + resolutions are high-quality training signals).
Coverage — three outcome classes
