/flow says in one sentence what is clogging the lane, and names a failing test shared by three pulls #11465

/flow now opens with a "What is clogging the lane" section, visible to admins only. It is pushed; I have not seen the forge's check verdict or a preview.

The keep_plan tool was not available in this session, so there is no plan on the issue.

What the section shows

• Bottleneck line: clogSays gives one sentence. It reads the standing clog's reasons, the vitals' conflicted count, the hottest file among learned pulls and the stranded dollars. With nothing to report it says "Nothing is clogging the lane."
• Shared red: sharedRed lists a test that fails on 3 or more open pulls of one repository, once, with those pulls linked. A pull's failing tests are taken from the last kept red gate (the stored result of a merge-queue check) that carried it. A pull no red gate has carried shows no failing tests.
• Pairs: conflictPairs lists pairs of open pulls that touch the same files, at most 20, each linked to both pulls. It reads the in-memory file lists the hot-files panel already keeps, so nothing runs git per request.

What moved

• The section is its own builder in src/web/pages/flow-clog.ts, mounted with one line in flow.ts.
• src/crew/hot_files.ts gains one accessor, learnedPulls(), which returns each repository's learned open pulls with their files.
• The three modules left scripts/unreached-allow.json.
• docs/features/flow-clog.md describes the section, and test/flow-clog-page.test.ts tests it through the page's HTML.
• The new test covers the empty state, one shared red with escaping and links, the conflict pairs, and two pulls failing a test not counting as shared.

Checks

• bun scripts/gate.ts, tsc --noEmit and design-lint ran clean. The new test, unreached, flow-valves and the hot-files tests pass.
• scripts/fast.ts exits 2 because unreached-allow.json changed, so I ran those test files by hand, not the whole suite.
• The pre-push hook wanted a commit saying how to try the change, so there is an empty "Try:" commit.

Not done

• I took no before/after looks, light or dark.
• The shared-red section covers repositories that have 3 or more open pulls learned in memory. It stays empty until the hot-files pass has learned those pulls.

Try it: sign in as an admin and open /flow. It is one tap from the Flow entry in the go-menu.

The "both doors" gate failed because this pull adds src/web/pages/flow-clog.ts without a terminal screen. I haven't added a screen. I pushed an empty commit with a No door: line, which the gate accepts instead of one.

flow-clog.ts isn't a page. It renders the one-sentence "what is clogging the lane" line inside the existing /flow page. That page already has its terminal screen and feature doc, and the No door: line says so.

bun scripts/gate.ts printed nothing locally and the push went through. I did not re-run tsc or the tests, since no code changed. The forge's check will run on the new push.

I fixed one of the three failures: /flow went over its first-view budget. I haven't touched the other two, and I haven't re-run the check.

• each page stays inside its first-view budget: the clog sentence added to /flow (112 words, 11 blocks, against budgets of 102 and 9) put the page over. I raised only the flow entry in docs/design/attention-budget.json, at both widths. bun test test/attention.test.ts passes locally. Regenerating the whole file with FORGE_ATTENTION_WRITE=1 would also have lowered other pages' budgets, so I edited it by hand.
• tui system telemetry grant and past its deep budget an address gets 429: I ran test/tui-system.test.ts and test/crawl-budget.test.ts locally, and they showed no failures. Neither exercises /flow or my change, so I'm treating them as flaky under the full-suite load. If they fail again on this push, I'll look at them properly.

The fix is pushed.

The clog sentence, the shared red test and the touching pairs now appear on both /flow and the terminal's Flow screen. /flow's attention budget is back to its old values. Items 1–3 and the line-comment tests are done; box 4 (before/after looks, light and dark) is not, because I can't take screenshots in this sandbox. The empty state is now unchanged, so a before/after only shows a difference when there is something to say.

• Terminal: a new readClogView (src/flow/clog_view.ts) does the reads once. /flow and the terminal's Flow screen both draw from it, so they show the same content. The terminal renders it through src/flow/clog_lines.ts. It is admin-only, and an agent's reading carries none of it.
• Design: src/web/pages/flow-clog.ts draws nothing when there is nothing to say. The h2 is gone and the sentence is the heading. The shared red rows follow the <ul class="list"> pattern: the test, then repo and linked pulls. Pairs use the same pattern. The "One clash: re-check…" advice is removed. I reverted docs/design/attention-budget.json to the old values, and bun scripts/design-lint.ts is clean.
• Honesty: readClogView returns empty while no pulls are learned after a boot, so the section stays blank instead of saying "Nothing is clogging the lane."
• Tests: test/flow-clog-page.test.ts now covers the absent section, the terminal lines, and the agent reading carrying none of it. It also adds two boundary tests:

- a pull no red gate carried is not counted toward a shared test; - a second repository with fewer than 3 open pulls is skipped even though its red gate names three pulls.

• Checks run: bun x tsc --noEmit and bun scripts/gate.ts are clean. 603 tests pass across the 98 flow, clog, TUI, budget and unreached test files, with 1 skipped. scripts/fast.ts exited 2 (diff too broad to name), so I picked those files myself.
• Doc: docs/features/flow-clog.md is updated to match.

One thing I left alone: the sentence stays blank whenever no pulls have been learned yet, rather than saying the pulls are still being read. That is the "show nothing" option from the review, so no extra words appear on the page.
