Verified best-practice

Every external quote below was re-checked against the raw page with curl -sL … | grep on 2026-09-03 (not only through a summarizing fetch), except where noted.

1. 520214f2e52d14c4 — sequential artifact numbers across parallel workers → confidence: verified. Claim: the coordinator assigns RFC/ADR/migration numbers at dispatch; a worker's branch point cannot see a sibling's unmerged number and distinct filenames merge without conflict, so the uniqueness lint runs on the merged tree. Sources: Django migrations topic ("two migrations with the same number"), Django makemigrations --merge ("Enables fixing of migration conflicts"), Rails 3.2 migrations guide (creation-time timestamps to avoid clashes), git-merge ("incorporated in the final result verbatim"), adr-tools issue fix(orchestrate): ORCH_DIR path token, watch-status stall gating + reason surfacing, merge-on-approval (#87–#90) #102 (two devs both denote ADR 6). Field evidence: linkly t112/t119 both created RFC-0034.
2. 3fb0fd84e5ec5aa4 — inbound validation ownership when a plan splits a process boundary across tasks → confidence: verified. Source: OWASP Input Validation Cheat Sheet ("as early as possible in the data flow, preferably as soon as the data is received from the external party"). Field evidence: agent-crew M2 handle_envelope missing validate() caught only by integration review.
3. e5bc5ce7cb8508b4 — vendor benchmark claims for a memory/RAG tool → confidence: verified. Sources: LoCoMo paper (arXiv 2402.17753), Zheng et al. LLM-as-a-judge (arXiv 2306.05685, "over 80% agreement"), Zep blog disputing Mem0's LoCoMo SOTA claim, Mem0's counter-reply (Revisiting Zep’s 84% LoCoMo Claim: Corrected Evaluation & 58.44% Accuracy getzep/zep-papers#5, "58.44%"), OpenViking stat_judge_result.py (QA and Import token usage counted separately) and judge.py ("be generous with your grading"). The candidate's judge.py:239 line reference no longer matches the 203-line file; the leniency instruction itself is confirmed and the page says so.
4. b5e0cd6b60242fb6 — element crop screenshots (clip from boundingBox()) → confidence: field-tested. Playwright semantics verified (element screenshot via locator.screenshot(), clip option, boundingBox() is viewport-relative and scroll-dependent); the Aside CLI clip misbehaviour itself is single-session field evidence, not reproduced here (no browser run). Directive generalised to: element-screenshot primitive first, read back the first crop before a batch, fall back to full-page capture on a persistent wrong-region clip.
5. a019efb64f7bf316 — WebFetch summary vs raw page → confidence: verified. Source: Claude Code tools reference ("runs the prompt against the content using a small, fast model. For most fetches, Claude receives that model's answer, not the raw page"; "use curl via Bash for the unprocessed page"). Field evidence re-confirmed: the tmap-skopenapi routeSequential30 page contains the exact string "경유지는 최대 30개까지 설정할 수 있습니다." in the raw response.
6. c2665906bb4df3a9 — Steps-prose resilience guarantee needs its own test → confidence: verified (merged into an already-verified page). Source: SWE book ch12 ("A behavior is any guarantee that a system makes…"). Field evidence: wt-t4-event-push task 03 auditor FAIL→PASS after one added test.
7. ee33bdf217330afe — split a CI fact-checker's "fabricated" verdict → confidence: verified for the evidence (dev-loop PR docs(wiki): mandatory design-skill routing for visual-design deliverables #164 is public and merged; commit f5d2395 message confirmed via gh api), directive itself field-tested; merged into a field-tested page.
8. e040b9a62688a56e — Depends-on table vs Steps prose → fold (see Open-PR check); field evidence only, no new external source claimed.
9. a3560e8f5bd8f249 — brief workers to write measured counts → fold; field evidence only (linkly t119 vs t112/t115/t117).
10. 0fa9c12c34ec038c — doc-currency gates inside the doc task → fold; field evidence only (linkly enf0829, 10 integration failures).
11. 4977fec4fae1c1db — route worker edits through Bash when the guard is Bash-only → fold; field evidence only. The claim that Edit/Write ignore cwd could not be confirmed in the Claude Code docs (only the Read tool section says "always pass absolute paths"), so the inserted row relies on the page's existing verified evidence that Edit/Write bypass a Bash-matched hook and does not state the cwd claim.
12. a2023caa7c6da204 — multi-name command -v → dropped, pending duplicate: PR knowledge: 12 insights — dropzone copy vs drop handlers, destination-in mask chaining, media-query inset reset, spatial clamp, env restore vs pop, synthetic-corpus floor, plan-claim recompute, multi-name command -v, alert suppression key, sibling validators (+2 folds) #181's path-resolution.md already carries this exact edge case, instead-of row, POSIX synopsis source and the same local reproduction.

Also read on open-PR heads (not on this checkout): checkable-claims-in-an-adopted-plan, sibling-validators-on-a-shared-node (#181); semantic-conflicts-after-parallel-merge, verify-command-in-a-worker-brief (#179); ours-resolution-on-a-mixed-content-conflict, forward-references-in-a-numbered-protocol (#180).

• Merged (3): WebFetch-summary case → harness-mediated-tool-results (new when-this-applies sentence, edge-case row, instead-of row, source, field context; index cell widened). Steps-prose guarantee → minimum-case-set (edge-case row, instead-of row, SWE-book quote + field evidence; index cell widened). Split verdict → evaluating-review-feedback (edge-case row, instead-of row, PR docs(wiki): mandatory design-skill routing for visual-design deliverables #164 source; index cell widened). None of these three pages is touched by an open knowledge PR.
• Created (4): infrastructure/agent-orchestration/sequential-identifiers-across-parallel-workers, infrastructure/agent-orchestration/inbound-validation-ownership-in-task-decomposition, backend/common/llm/vendor-benchmark-claims-for-an-llm-tool, qa/environments/element-crop-screenshots. Each has an index row and a log line.
• Conflicts flagged: none. The inbound-validation page agrees with security-input-validation-at-trust-boundaries ("validate at the consumer boundary anyway") and adds the task-decomposition angle.
• Related links: new pages link to existing ones; back-links added on qa-process-adversarial-change-review, backend-common-llm-context-window-budget, qa-process-llm-review-pipelines, qa-environments-browser-console-capture-gaps, qa-bug-reports-reproducible-reports.

Routing decision

Insight	Target
520214f2 sequential numbers	infrastructure/agent-orchestration/sequential-identifiers-across-parallel-workers — NEW page; agent-orchestration already owns worker briefs and shared run state
3fb0fd84 inbound validation ownership	infrastructure/agent-orchestration/inbound-validation-ownership-in-task-decomposition — NEW page; the lesson is about which task's brief carries the decision, so orchestration rather than security (linked to the security page)
e5bc5ce7 vendor benchmark claims	backend/common/llm/vendor-benchmark-claims-for-an-llm-tool — NEW page; backend/common/llm owns consuming LLM tooling; no new category needed
b5e0cd6b element crop screenshots	qa/environments/element-crop-screenshots — NEW page; qa/environments already holds browser-tooling gaps (console capture, bot blocking)
a019efb6 WebFetch summary	merged into platforms/tools/harness-mediated-tool-results — same class (a tool result mediated before the agent sees it)
c2665906 Steps-prose guarantee	merged into testing/quality/minimum-case-set — it is a "which cases are required" rule
ee33bdf2 split verdict	merged into qa/process/evaluating-review-feedback — it is a response-to-review-finding rule
e040b9a6 / a3560e8f / 0fa9c12c / 4977fec4	folded into PR #181 / #180 / #179 / #179 pages respectively (see Open-PR check)
a2023caa multi-name command -v	dropped — already on #181 platforms/environment/path-resolution

No new category was added; every insight fit an existing domain/category.
