Knowledge flush — 12 insight(s)

Run 20260906-213602-52875 (headless auto-flush), branch knowledge/choiyounggi-20260906-213635.
Claimed 12 rows with queue-claim.js claim --max 12; 18 rows remain pending for later flushes.
Outcome: 6 new pages, 5 merges into existing pages (one reconciling a contradiction), 0 drops, 0 folds.

Verified best-practice

1. Pointer-attracted particle field collapses (8a6e99abdfe31e54) — p += (t−p)·k with a
   stationary pointer is a contraction; nodes converge onto the cursor. Sources checked:
   Wikipedia Banach fixed-point theorem ("admits a unique fixed point"), MDN pointerleave
   ("moved out of the hit test boundaries"), MDN requestAnimationFrame ("paused in most
   browsers when running in background tabs"). Field: cover-letter review
   .orchestration/reviews/t2-hero-code-intro-r1.md F1 (collapse to ~8.7e-8 px; fix
   POINTER_INNER_RADIUS=32, clamped step, out-of-bounds null, 1000-step test; 374 green).
   Confidence: verified (mechanism doc-backed; numbers field).
2. Firecrawl onlyMainContent drops the regions that hold contact details (407808eb70bcaf43)
   — docs.firecrawl.dev /scrape reference: onlyMainContent default true, "Only return the
   main content of the page excluding headers, navs, footers, etc."; includeTags/excludeTags
   exist. tel: preservation is not documented — kept as field data (22/30 sites expose tel:,
   16/30 have the number only outside main content, 0/30 gain a number from JS rendering).
   Confidence: verified (mechanism) with the survey stated as field measurement.
3. "Ask the user" binds only when the question tool is named and a hook checks the transcript
   (ebbe51aeb2082d16) — code.claude.com hooks doc: PreToolUse input carries transcript_path,
   exit code 2 blocks. dev-loop PR feat: adopt mattpocock/skills practices — frontier-rounds gates, feedback-loop-first wiki, version gate #136 (merged 2026-08-23) introduced the wording without the
   tool name; PR feat(orchestrate): every human gate is an AskUserQuestion chooser (v1.11.0) #144 (merged 2026-08-25) named AskUserQuestion and added
   hooks/orchestrate-ask-gate.sh (present on main; 27 bats cases). Confidence: field-tested
   directive on top of doc-verified hook mechanics (page stays field-tested).
4. Column-0 line in run: | silently unregisters a workflow (d5776de0b6e9bedb) — YAML 1.2.2
   §8.1.2 "terminated when encountering a line which is less indented"; GitHub workflow-syntax
   doc: without name the file path is displayed; gh workflow run manual: needs
   on.workflow_dispatch. Local repro: Ruby Psych fails at line 13 column 1; two -m flags
   parse. Field: groundwork PR knowledge: keg-only PATH, tmux bracketed-paste, import-time side effects in unit tests #16 (merged; 422 before, sync dev-loop pin listed after). The
   "listed as active with no triggers" behavior is observed, not documented — said so on the
   page. Confidence: verified.
5. Actions may not create PRs until the repo setting is on (e88fdc004757a742) — docs.github.com
   Actions settings page ("Allow GitHub Actions to create and approve pull requests") and REST
   actions/permissions/workflow with can_approve_pull_request_reviews. groundwork now reports
   true; PR knowledge: source a hand-off deliverable from the generator, not by hand (qa/deliverables) #18 (bot, closed) → knowledge: 9 insights — differential-run agreement, completion predicates, robots.txt source selection, client-side rate limiting, call-site migration (+5 amendments) #22 (bot, merged). Confidence: verified.
6. Personal-repo ruleset refuses an Integration bypass actor (d58c3d2dc6afce8f) — REST
   rules reference lists Integration as an actor type; the personal-repo 422 is NOT in the
   docs (agent searched; only OrganizationAdmin is documented as personal-inapplicable). Field:
   groundwork ruleset 21371046 exists with bypass_actors: [], pull_request rule at 0
   approvals, required checks bats/shellcheck/version-sync. Row marked field-observed on the
   page; the page as a whole stays verified because the recommended path (PR + self-merge)
   rests on documented settings.
7. GITHUB_TOKEN-pushed branches get no check runs (5a15e973f89b9ab8) — docs.github.com
   github_token: "events triggered by the GITHUB_TOKEN will not create a new workflow run"
   (exceptions workflow_dispatch/repository_dispatch); PAT/App token advised. gh pr merge
   manual (--auto, --delete-branch), auto-delete-branches doc, gh pr merge --auto -d does not delete the branch after merge cli/cli#9073 (open: --auto -d
   does not delete). Field re-checked live: PR knowledge: 9 insights — differential-run agreement, completion predicates, robots.txt source selection, client-side rate limiting, call-site migration (+5 amendments) #22 check-runs total_count=0, knowledge: import-time test coupling, empty-data surveys, call-site census, shell off-switches #25 and v1.1.0 — complete the Orca delegation substrate #27 = 6,
   delete_branch_on_merge=true. Confidence: verified.
8. testcontainers.community.redis (401fd399afd7f97b) — upstream src/testcontainers/redis.py
   shim emits the exact DeprecationWarning; community/redis/__init__.py is the new home;
   commit ab6cca8e (2026-06-05) in release testcontainers-v4.15.0 (PyPI 2026-07-24). Local
   repro in a fresh Python 3.13 venv: warning printed, same class object, identical constructor
   signature, 45 shims ↔ 45 community/ packages. Confidence: verified.
9. Reproduce a shell bug under the script's own interpreter (c04820c7f2947876) — bash manual
   Aliases ("Aliases are not expanded when the shell is not interactive"), Bash Startup Files,
   zsh Files (.zshrc only "if the shell is interactive"). Field: dev-loop issue orchestrate: send-prompt.sh still reports 'delivered' for an unsubmitted paste — pane_tail's 6-line window drops the [Pasted text] marker (follow-up to #96) #145 (exists,
   closed). On this machine today command -v grep is /usr/bin/grep in both contexts, so the
   ugrep half is field-only; the directive is doc-backed. Confidence: verified mechanism,
   field example.
10. Assertion boundary vs symptom (c4350dda424a817e) — Wikipedia Regression testing ("record a
    test that exposes the bug"); field: linkly-crew PR knowledge: spec-document gates (4 axes + controls) and non-ASCII grep matching #10 (public, merged) core.rs:426-431.
    Confidence: field-tested rows on two field-tested/verified pages.
11. Mock fabricates an id the producer formats differently (7ad0888f88a13776) — Google Testing
    Blog "Don't mock types you don't own" ("assumptions built into mocks may get out of date"),
    Fowler ContractTest, Pact docs; field: linkly-crew PR knowledge: spec-document gates (4 axes + controls) and non-ASCII grep matching #10 (derive.ts vs dispatch.rs,
    0/125 → 25/25). A Stripe "ids are opaque" quote the agent could not re-fetch was NOT cited.
    Confidence: verified.
12. Homebrew clang ignores SDKROOT (57aa89b96c58268f) — the trigger already had a page
    (compiler-sysroot-on-macos, verified 2026-08-29) whose step-2 row says "Export SDKROOT;
    clang reads it as the default sysroot". Local repro on Homebrew clang 22.1.8 CONTRADICTS
    that row for Homebrew LLVM: clang -### loads
    etc/clang/arm64-apple-darwin25.cfg = -isysroot …/MacOSX26.sdk (absent), so SDKROOT
    (unset / xcrun path / CLT path) all fail; -isysroot works; --no-default-config +
    SDKROOT works. Mechanism sourced: clang UsersManual configuration files
    (--no-default-config), Homebrew llvm.rb write_config_files. The candidate's own
    "SDKROOT is not a fix" claim is therefore correct for Homebrew LLVM only, so the
    contradiction was reconciled as a condition (see routing). Confidence: verified.

• grep of main for workflow_dispatch, can_approve, bypass_actors, GITHUB_TOKEN,
  testcontainers, firecrawl/onlyMainContent, wire format: no hits → new pages 1–6.
• AskUserQuestion hits only unattended-worker-questions (worker-side out-of-band channel; a
  different trigger) → merged into binding-instructions-for-agents (body rows + sources; the
  related: line was left untouched because knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179 rewrites it — the back-link to
  unattended-worker-questions is in the new edge-case row text instead).
• sysroot hits compiler-sysroot-on-macos → conflict flagged and reconciled: the step-2
  SDKROOT row now carries the "when no -isysroot reaches the driver" condition, a new edge
  row explains the Homebrew config file, an Instead-of row and three Sources bullets were added;
  log.md records it as a reconciled contradiction. Frontmatter untouched (knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179 rewrites
  related:), so the new URLs live in the body Sources section only.
• reproduce-first (untouched by any open PR): two edge rows + two Instead-of rows + sources +
  frontmatter (sources, last_verified, related += path-resolution, completion-claims).
• completion-claims: one claim/evidence row inserted after "Bug fixed" and one Sources bullet
  before the superpowers bullet — positions chosen so knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179's hunks (last table row, appended
  sources) stay one unchanged line away. Frontmatter untouched (knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179 rewrites it).
• what-to-mock: one edge-case row linking the new producer-wire-format page; knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179/knowledge: 9 insights — fresh-context review, gate parser/executor split, coordinator under tmux, sun_path limit, REPL sentinel await, allowlist bypass reproduction, version-drift gate, mock ts at emit (+3 folds onto #180/#181, 1 stale drop) #183 rewrite
  its frontmatter and knowledge: 9 insights — fresh-context review, gate parser/executor split, coordinator under tmux, sun_path limit, REPL sentinel await, allowlist bypass reproduction, version-drift gate, mock ts at emit (+3 folds onto #180/#181, 1 stale drop) #183 edits the Do table and Sources, so nothing else was touched.
• Back-links NOT added (frontmatter owned by open PRs): html-in-canvas → pointer page (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),
  what-to-mock → producer-wire-format (knowledge: 12 insights — deny rules under bypass, merged-tree gate, worker verify command, Kotlin daemon heap, extracted-method this (+7 merges) #179/knowledge: 9 insights — fresh-context review, gate parser/executor split, coordinator under tmux, sun_path limit, REPL sentinel await, allowlist bypass reproduction, version-drift gate, mock ts at emit (+3 folds onto #180/#181, 1 stale drop) #183), unattended-worker-questions → binding
  instructions (frontmatter untouched by PRs but the row text link suffices).
• Index rows: 6 new rows (infrastructure ci-cd ×2, backend integrations, testing data, testing
  mocking, frontend design); load-when text extended on compiler-sysroot (platforms),
  binding-instructions (backend), reproduce-first (debugging), completion-claims (qa).
• Lint: wiki-structure-checks.js wiki 282 pages / 0 findings; wiki-lint-prohibitions.js wiki
  0 violations; every new page ≤ 65 body lines, merged pages ≤ 94.

Open-PR check

Open knowledge/* heads listed and fetched: #186 (20260906-013856), #185 (20260906-003745),
#183 (20260904-133717), #182 (20260903-214027), #181 (20260903-203836), #180 (20260903-184706),
#179 (20260903-172728). Each diffed against origin/main -- wiki/ and grepped for the candidate
terms (GitHub Actions, GITHUB_TOKEN, firecrawl, community.redis, AskUserQuestion, corr-, ugrep,
/bin/sh, assertion boundary, wire format).

No fold and no pending-duplicate drop this run. The earlier sibling hash 35922b00 (same
sysroot trigger, 2026-08-05) is already processed; this row added the config-file mechanism
that page lacked, so it was merged rather than dropped.

Routing decision

No new category: ci-cd, integrations, data, design, mocking, methodology, process, llm and
toolchains all cover their candidates' triggers under their existing "route here" lines.
