Rolling retrospective learnings

This PR accumulates one dated section of learnings per day (from merged PRs and engineer-bot author runs) until it is merged; merging it starts a fresh one. The bot never writes the canonical log directly.

Latest update 2026-10-31: 2 new learning(s) since 2026-10-30T17:24:41Z.

Verdict: 1 Low

Documentation-only PR: it appends dated retrospective learning sections to .claude/knowledge/learning-log.md, with no executable code to review. One low-severity doc-consistency issue — the appended ## Entries section leaves the stale "No learnings have been recorded yet" preamble in place, now contradicted by the content below it (also missing a blank line before the heading). Otherwise looks good.

🔵 Low — This PR appends the first ## Entries section directly beneath the preamble paragraph that still reads "No learnings have been recorded yet — the first retrospective PR will append the initial dated section below." Since this is that first retrospective PR and it now adds many dated sections, the sentence immediately above ## Entries is false the moment this merges — a reader sees "no learnings recorded yet" followed by 20+ learning sections.

When the retrospective flow writes the initial section, it should also replace (or drop) that placeholder sentence so the preamble no longer contradicts the content below it.

Minor secondary nit on the same line: ## Entries is appended with no blank line separating it from the preceding paragraph. CommonMark lets an ATX heading interrupt a paragraph so it still renders, but a blank line before the heading is the house style elsewhere in this file and avoids renderer-specific surprises.

Verdict: 1 Low

Looks good. This PR only adds learning-log entries, plus one low-severity fix: the file's preamble is out of date. I checked the new 2026-10-31 KEQ_SEQ claim, and it matches lib/thrift-backend/primaryKeysSchema.ts:5-10.

[peco-review-bot]

🔵 Low — The preamble right above the new ## Entries heading still says "No learnings have been recorded yet". This PR adds 17 dated sections, so that sentence is now wrong. The author flow reads this file back as knowledge, so it will see a statement that contradicts the rest of the file. Also, ## Entries comes straight after the paragraph with no blank line in between. Most Markdown renderers still treat it as a heading, but markdownlint (MD022) flags it, and it doesn't match the spacing used elsewhere in the file. Replace the stale sentence (for example, "Dated sections are appended below.") and add a blank line before ## Entries.
