…ories) The suite has become a drag on development: 864 test cases, 11,341 lines of test against 13,369 lines of source in apps/web, four open test-reliability known issues, and a unit suite that spends more time constructing jsdom worlds than running assertions. Measured on this tree before planning, so the phases are aimed at real costs: - apps/web unit: 95 files / 569 tests / 43.1s, of which `environment` (jsdom construction) is 58.7s against `tests` 22.5s — 2.6x more time building DOMs than asserting. - packages/domain: 22 files / 129 tests / 2.6s (`environment` 4ms). Same repo, same tooling — the difference is entirely the DOM. - 35 of 95 web unit files need no DOM at all. A probe config giving them the node environment: 43.1s -> 35.2s wall, `environment` 58.7s -> 36.6s. - `--no-isolate`, the obvious next lever, produces 248 failures. Recorded so nobody re-derives it. - e2e is the healthy layer: 15 tests, already role-first (182 getByRole vs 4 raw CSS locators), but signs in through the real UI 24 times and runs at a single viewport. Eight phases, ordered so the risky work happens last and on a foundation that can catch it: baseline -> config-only wins -> typed factories -> e2e -> KI-13 -> prune -> de-brittle -> guidelines and lint enforcement. Closes as scoped work: KI-13, KI-19, KI-21, KI-25. KI-11 is explicitly left open (a missing capability, not a flake) with a cheaper home noted.

Three decisions taken (Mitchell, 2026-08-23) and a handoff brief written to the repo's KICKOFF convention. Sequencing: the plan is SPLIT. Phases 0-4 run now; Phases 5-7 wait for M10 Wave 2's gate. M10 Phases 5-8 are unstarted and touch TimelineLens.tsx (three of them), ActivityEditor.tsx and its own test file, dayAccent.ts, DayChips, CalendarLens, TripHeader, Board and app/page.tsx — eight of this plan's largest prune/de-brittle targets. The argument is not mainly merge conflicts: pruning ActivityEditor.test.tsx before M10 Phase 7 rebuilds the component is work done twice. Phases 0-4 touch config, e2e and test data, so they deliver the speed and flake fixes during the M10 work that most needs them. Factories: packages/factories (@tc/factories), a fifth workspace package. Alternatives weighed and recorded in the phase file so the ADR can close them. Pruning: no deletion target. The earlier "≥35%" figure is removed — a quota is the pressure that pushes a cut past what the safety protocol supports. Apply the criteria, report the resulting number. The one hard floor stays: domain coverage must not drop. Also fixes an internal contradiction in phase 4: the plan's DoD said "KI-13 closed" while the phase allowed keeping it open. KI-13 has failed to reproduce once before, so the phase now carries an explicit three-outcome decision table covering reproduce-and-fix, cannot-reproduce, and reproduce-but-unfixed.

Phase 0 Tasks 0.2 and 0.3 of the test-overhaul plan, done ahead of handoff because the keep/cut verdict on 131 test files is the judgment-heavy step the rest of the plan depends on. Method is two passes, because one is not enough: 1. Coverage (deterministic). Every test file run in ISOLATION with v8 coverage, per-file statement maps intersected. scripts/coverage-overlap.mjs does this — `collect` ~9 min, `report` instant. Aggregate whole-suite coverage cannot answer this; it collapses exactly the per-test contribution we need separated. 2. Intent (judgment). What regression would each test actually catch. Both are required, and the data shows why. Coverage says a line RAN, not that a test would NOTICE it changing. Two documented failures of coverage-only: `equality.test.ts` scored 0% unique / 100% overlapped on a whole-footprint measure while `tripStatesEqual` is asserted nowhere else (shared imports drown the signal — fixed by scoping to each test's named subject); and even scoped, `formatMoney.test.ts` reads as 100% subsumed by page.test.tsx, which merely EXECUTES those statements while formatMoney.test.ts is the only place asserting the output string — the KI-2 guarantee. Coverage narrowed 131 files to 66 candidates; intent found roughly half of those were false positives. The finding that most changes how Phase 5 should read the data: in 16 of 66 subsumption pairs the "subsumed" file is a pure-function test at the correct layer and the subsumer is an expensive jsdom component test. The cut goes the OTHER way. Coverage identifies the pair; the layer rule decides direction. Proposed net: -168 tests (~19% of 864), -24 jsdom files. No target was set; this is what the criteria produced. Also files two findings against KI-18, both found while reading the pair: sparklineColor.ts already solved the identical hash-collision problem and documents the fix, so M10 Phase 8 should read it before writing dayAccents(cities); and dayAccent.test.ts passes today while KI-18 is broken, so the fix must replace that test, not just the function.

The kickoff told the builder to branch from origin/main. The plan, the inventory and scripts/coverage-overlap.mjs are not on main — they exist only on claude/next-phases-work-vni3iz — so that would have produced a tree with none of the documents the brief tells the agent to read. Branch from the planning branch instead (docs-only, currently 0 commits behind main), with a note on what to do if main moves or the branch lands first.

…sifier script Task 0.1: clean three-run timing for web unit, domain, contracts, and pages suites (no concurrent load) — all green, zero flakes. This sandbox runs ~1.4-1.5x slower than the plan's reference hardware, but the environment-vs-tests ratio that motivates Phase 1 is, if anything, more pronounced here (2.7-2.9x vs 2.6x). Task 0.2: adds scripts/classify-test-envs.mjs, which was missing from the tree despite being marked done — only its answer had been recorded. 34 of 95 web unit files verified node-safe (one off the recorded 35; immaterial). Task 0.4: packages/domain coverage floor recorded (97.09% stmts, 93.3% branch on src/trip/*.ts) for Phase 5/6 to measure against later. Full numbers and method in docs/testing-baseline.md. Nothing deleted, no test content changed.
pageTools.test.ts's classification flipped to a false positive because the
heuristic's document./window./navigator. regex matched prose in a comment
("...before it ever reaches a document. execute()...") as if it were real
DOM usage. Stripping comments before scanning fixes it — 35 of 95 web unit
files are node-safe, exactly matching docs/testing-inventory.md's recorded
number (previously mismeasured at 34 due to this bug). All 35 verified
green under --environment=node.
Task 1.1: vitest.unit.config.ts now defaults to node and opts DOM-touching files back into jsdom via environmentMatchGlobs (all *.test.tsx, plus the four .ts files Phase 0 found need a real document). All 569 tests still pass; environment time drops from a ~88s baseline median to ~60s on a single verification run (a full clean 3-run comparison is being recorded in docs/testing-baseline.md in a follow-up commit). Task 1.2: isolate: false stays off, documented in-config with the measured 248-failure count so it isn't rediscovered. Task 1.3: poolOptions.threads capped at 4 to keep this suite from compounding pnpm -r's own per-package parallelism on a small machine (KI-13's confirmed starvation mechanism). Task 1.4: playwright.config.ts now sets an explicit 1280x900 viewport (KI-19's blind spot — no viewport meant every e2e run defaulted to 720px tall, which is why KI-21's dragCardTo auto-scroll poll never completed in time), trace: on-first-retry, and one CI-only retry (a flake label is a bug report, not something to wave through — see KI-1). Zero test content changed.
Three clean post-Phase-1 runs, same machine-idle protocol as the Phase 0 baseline: environment median 88.29s -> 58.73s (33.5%, past the >=30% target), zero flakes, 569/569 every run.
New workspace package packages/factories (Fishery + @faker-js/faker, both
dev-only — Fishery is the composition mechanism, faker supplies realistic
values inside factories, never used to generate whole objects): leaf
factories typed against @tc/contracts, tripDetailFactory computing its
rollups via @tc/domain's rollupCosts (never re-derived), named scenario
builders, and commandsFor(scenario, tripId) — the event-sourced command
stream unit tests' projections don't need but e2e/db:seed do.
src/mocks/fixtures.ts is deleted; its 24 callers' imports move to
@tc/factories with zero body changes (a legacy.ts module carries the old
fixtures' exact output forward verbatim, so this is provably a no-op for
every existing assertion — 569/569 unit tests unchanged).
e2e/helpers.ts's createMappedTrip is now a thin commandsFor("mappedTrip")
wrapper, special-cased inside commandsFor to reproduce its old literal
output exactly (m10-unscheduled-rack.spec.ts asserts on it by string).
scripts/db-seed.mjs becomes db-seed.ts, typed against TripCommand via
Node's native type stripping (zero new dependencies) — but deliberately
NOT routed through commandsFor's generic scenarios, which would flatten
its three specific, narratively real demo trips (a 14-day/68-stop Japan
itinerary among them) into generic placeholder data. See ADR-020's
Consequences section.
Task 2.6: audited all 11 *.int.test.ts files with beforeEach truncation.
Discovered rebuildProjections() does a global, unscoped table rebuild —
4 of the 11 files call it, which rules out removing truncation suite-wide
as the plan assumed. De-truncated the 7 files verified to only ever
read/write their own randomUUID()-scoped tripId; left the other 4
untouched pending a real fix to rebuildProjections's scope or a
multi-project Vitest split (out of scope for this session). Measured
before/after: test execution time drops ~13% (2.02s -> ~1.78s), wall time
roughly unchanged (collection dominates, not truncation) — reported
honestly rather than overstated. Full writeup in docs/testing-baseline.md.
pnpm check green; full apps/web + factories test suites green (569 + 4
unit, 79 int); db-seed.ts verified end-to-end against a live server
(idempotent re-run included); e2e/m10-unscheduled-rack + m10-map-rail
specs verified green against the new createMappedTrip.
Task 3.1: e2e/auth.setup.ts authenticates as alice once and saves
storageState; playwright.config.ts's desktop/narrow projects depend on it
and start pre-authenticated. signInAsDevUser is now called from exactly one
place (auth.setup.ts) — smoke.spec.ts keeps its own independent inline
sign-in flow, the one spec still covering the login UI end to end.
Isolation strategy: kept the existing unique-trip-name convention rather
than per-worker dev users (both acceptable per the plan; written down here).
Task 3.3 (KI-21): dragCardTo now scrolls the drop target into view BEFORE
starting the drag instead of depending on drag-triggered auto-scroll to
finish inside a hand-rolled 5s polling budget — removes the race rather
than widening the window. The polling loop and all 3 waitForTimeout calls
are gone; every caller already asserts the drop's result with a web-first
toBeVisible()/toHaveCount(), which Playwright's own auto-waiting already
retries. Verified: m1-board + m4-money-and-lenses green 10 consecutive
runs idle, plus 2 more under full CPU saturation (12/12).
Task 3.4 (KI-19): playwright.config.ts gains a "narrow" (1100x800) project
running only the new e2e/responsive.spec.ts — 5 tests covering every
breakpoint-dependent behavior the app has (assistant rail overlay + scrim
dismiss / KI-16 guard, view-tab interactivity, a sheet's Close button
staying reachable / KI-17, the Playbooks strip's 1180px reflow, the home
hero's 1024px collapse), asserted via role queries and getComputedStyle,
never a className.
Task 3.5 (KI-25): new unauthenticated GET /api/health/ai-mode reports
modelSelection.ts's own aiLive() (not a second copy of the logic).
playwright.config.ts's new globalSetup (e2e/global.setup.ts) queries it
once before every project and throws if live — independent of how the
server was started. Verified both directions: a live-mode server with
reuseExistingServer (KI-25's exact scenario) makes the suite refuse to run;
AI_LIVE=false is unaffected.
Also fixed, found during this session's own verification: m8-make-it-
real.spec.ts's delete/undo assertions raced the "Deleted "{name}"" undo
toast's own text (the same substring-collision class a comment two lines
above had already named for a different assertion in the same file) —
rescoped to getByRole("heading", { level: 3 }), matching smoke.spec.ts's
own pattern for trip cards. 5/5 clean after the fix.
Full suite: test:e2e:ci-like green 21/21 (1 setup + 15 original + 5 new),
twice in a row. KI-19, KI-21, KI-25 moved to Resolved in known-issues.md.
Full writeup in docs/testing-baseline.md.
…on demand Saturates every core, then runs the apps/web unit suite — the 2026-08-16 reproduction condition, scripted so a future session doesn't reconstruct it by hand (Phase 4 Task 4.1).
Task 4.1: scripts/repro-ki13.sh (already committed) run against both the
pre- and post-Phase-1 vitest.unit.config.ts under full CPU saturation.
Neither reproduced KI-13's failure mode: 95/95 files, 569/569 tests green
both times, matching the KI's own prior 2026-07-28 non-reproduction on an
idle 10-core machine.
Task 4.4's three-times proof: pnpm check green 3x idle, and 3x under
scripts/repro-ki13.sh saturation — 6/6, zero failures. The cold-install
condition was not retested this session; recorded honestly in both
known-issues.md and testing-baseline.md rather than claiming a bar this
session didn't clear.
Per phase-4-ki13.md's own decision-rule table (row 2 — cannot reproduce on
either config, all proofs green): KI-13 is closed as no longer
reproducible, explicitly NOT as root-caused. The mechanism (wall-clock
waitFor starvation under load) was never directly observed this session.
Task 4.2, applied regardless of the reproduction outcome: MoneyInput.test.tsx
(KI-13's own canonical slow file, 11,675ms in-suite vs 191ms alone),
toast.test.tsx, and LocationInput.test.tsx now use
userEvent.setup({ delay: null }) instead of the default import — none of
the three components has an internal timer; the cost was userEvent's own
default per-keystroke setTimeout, confirmed by reading its wait() helper
(only schedules a real timer when delay is a number, which the default 0
is). debounce.test.ts and SyncIndicator.test.tsx, the other named
candidates, audited and found already correct — no change needed.
Full writeup in docs/testing-baseline.md; docs/known-issues.md's KI-13 entry
moved to Resolved with the same honest framing.
Phases 0-4 landed ahead of M10 Wave 2 Phase 5, per AGENTS.md's scope-creep rule — same pattern the 2026-08-19 feature-flags insert used. Does not move or reopen M10's gate; Phase 5 remains the resume-from-here point.
…rification m8-make-it-real.spec.ts's trip-actions menu timed out once with its Delete menuitem outside the viewport, then passed clean on Playwright's automatic retry. Unrelated to and distinct from this session's other m8 fix (a getByText substring collision) and from KI-19/21/25/13 — filed rather than silently absorbed or ignored, per the project's own culture around flakes. Not fixed here: needs a trace-level look before touching Popover's collision config, and it's outside Phases 0-4's named scope.

In `@apps/web/e2e/helpers.ts`:
- Around line 33-43: Update dragCardTo so it captures the source position and
starts the mouse drag before calling target.scrollIntoViewIfNeeded(), then
recalculate target’s viewport-relative bounding box after scrolling and complete
the drag using the updated coordinates. Add coverage for a distant day-to-day
drag, such as day 1 to day 3.
In `@apps/web/package.json`:
- Line 21: Update the db:seed setup to support unflagged native TypeScript
execution by aligning the engines.node declaration and developer documentation
with Node 22.18.0 or later, or replace the direct scripts/db-seed.ts invocation
with the repository’s supported TypeScript runner; do not add a runtime
dependency for the type-only `@tc/contracts` import.
In `@docs/plans/2026-08-23-test-suite-overhaul.md`:
- Around line 181-188: Align the KI-13 closure contract across both plan
documents: in docs/plans/2026-08-23-test-suite-overhaul.md lines 181-188, allow
KI-13 to be resolved or honestly re-scoped per Phase 4; in
docs/plans/test-overhaul/phase-4-ki13.md lines 1-3, remove or condition the
unconditional “Closes KI-13” wording so it depends on the exit evidence.
In `@docs/plans/test-overhaul/phase-2-factories.md`:
- Around line 145-165: Update the commandsFor API to accept typed, per-scenario
override options, including required mappedTrip parameters such as dayCount,
while preserving scenario-specific validation and command generation. Define the
options type alongside the scenarios vocabulary so callers can use
commandsFor("mappedTrip", { dayCount }) before migrating integration, e2e, and
seed callers.
In `@docs/plans/test-overhaul/phase-3-e2e.md`:
- Around line 155-156: Update the Task 3.4 acceptance criteria and exit
checklist to require a default-run hero check at 1000px, using either a
dedicated narrow project or a per-test page.setViewportSize configuration.
Ensure the 1040px collapse behavior is exercised alongside the existing 1100px
project.
- Around line 175-180: Update the e2e global setup AI-mode guard to create an
APIRequestContext, reject non-OK responses, invalid JSON, and any response whose
body.live is not exactly false, and dispose the context in a finally block so
cleanup occurs even when the request or parsing fails.
In `@docs/plans/test-overhaul/phase-4-ki13.md`:
- Around line 36-37: Update the reproduction harness script around the Vitest
command so it runs the required pnpm check command three times under full CPU
saturation, or accepts and executes a caller-provided command with arguments.
Preserve the existing process cleanup behavior after each run and ensure the
default invocation produces the checklist-required evidence.
- Around line 33-38: Update the CPU saturation loop to record each spawned
worker PID and register an EXIT trap that terminates all recorded workers on
every exit path, including interruption or signals. Remove the job-number-based
cleanup using jobs and percent references, while preserving the existing Vitest
command and worker-count behavior.
In `@docs/plans/test-overhaul/phase-5-prune.md`:
- Around line 37-47: The framework-test deletion criterion should target only
tests that directly assert unchanged framework behavior without component-owned
logic. In the guidance around the Heading example, retain tests covering
semantic or accessibility behavior such as the level-to-tag mapping and heading
role, while limiting deletions to pure pass-through assertions like basic dialog
opening, href presence, or onClick forwarding.
In `@docs/plans/test-overhaul/phase-6-debrittle.md`:
- Around line 75-86: The testing guidance should retain a user-visible
rendered-value assertion for component money tests, while keeping rounding and
locale behavior covered only by formatMoney.test.ts. Update the “exact formatted
money string in a component test” row to distinguish formatter-input
verification from asserting that the component displays the formatter’s returned
value.
- Around line 110-123: Update the dayAccent.ts property test to require distinct
accents only for up to five distinct non-null cities, matching ACCENT_FAMILIES
capacity; add a separate assertion documenting the expected degradation when
inputs contain more than five such cities, while retaining the witness with its
measured floor.
In `@docs/plans/test-overhaul/phase-7-guidelines.md`:
- Around line 163-165: Update the checklist entry for docs/known-issues.md so
resolved issues record verified evidence and disposition, requiring an actual
root cause only when the evidence establishes one; preserve the KI-11
model-harness note.
In `@docs/testing-baseline.md`:
- Around line 48-52: Update the Tests column in both unit-suite tables,
identified by their Run rows, replacing 95 with 569 for every listed run while
leaving the Files column values unchanged.
In `@docs/testing-inventory.md`:
- Around line 76-87: Update the testing inventory to match the verified counts
in docs/testing-baseline.md, including packages/pages, apps/web integration, and
apps/web e2e; recalculate the 864 headline and proposed net from those current
totals. Revise the Phase 0 status text in the inventory’s later historical
section so it no longer claims incomplete work or unavailable Postgres, or
explicitly label the entire document as a pre-overhaul snapshot if retaining
historical figures.
In `@packages/factories/src/commands.ts`:
- Around line 53-55: Update commandsFor and the additional affected
command-generation paths to use a fixed or injected clock instead of new Date(),
and derive generated day IDs deterministically from stable inputs such as tripId
and scenario position instead of randomUUID(). Preserve the existing command
stream structure while ensuring identical inputs produce identical dates and
IDs.
In `@packages/factories/src/scenarios.ts`:
- Around line 62-67: Update the transient configuration in ungeocodedTrip to use
the factory’s name-only location mode, producing locations with a name but no
lat/lng instead of null locations; add the mode to the relevant
location-generation logic if it does not already exist, while preserving the
scenario’s existing dayCount, activitiesPerDay, and startDate values.
In `@packages/factories/src/trip.ts`:
- Around line 91-93: Update the activity ID salt in the trip factory’s
activityIds generation to use an offset derived from activitiesPerDay,
preventing collisions across days when a day has more than 10 activities. Add a
factory test covering two days with 11 activities per day and verify every
scheduled activity ID is unique.
In `@scripts/coverage-overlap.mjs`:
- Around line 66-69: Update the coverage collection flow around the catch
handler and report() so any failed Vitest entry causes the command to print the
failed files and exit nonzero after collection; make report() reject indexes
containing entries with ok: false instead of filtering them out, preventing
reports from incomplete coverage data.
In `@scripts/repro-ki13.sh`:
- Around line 2-6: Update the KI-13 reproduction script comments to remove the
claim that wall-clock starvation is a confirmed root cause. Describe the
scenario as a historical diagnostic reproduction of the previously observed
condition, consistent with KI-13’s unresolved root cause and
no-longer-reproducible status.

- packages/factories: fix activity-id collision once a day has more than 10 activities (was dayIndex*10+i, now scoped by activitiesPerDay); add a "named" location mode so ungeocodedTrip's scenario matches its own comment (a named-but-unenriched AI-planned place, not no location at all) instead of producing location: null - e2e/global.setup.ts: fail closed instead of open when the AI-mode health check errors or returns malformed JSON, so e2e never silently proceeds against a server whose simulated-AI mode isn't confirmed - e2e/helpers.ts: fix dragCardTo ordering — mouse-down at the source now happens before scrolling to the target, so a distant source can't be scrolled out of view before its bounding box is read - bump engines.node to >=22.18.0, matching the native TS-stripping requirement db-seed.ts already depends on - coverage-overlap.mjs: collect() now reports failed files and exits non-zero instead of silently writing an incomplete index - correct wording in repro-ki13.sh and phase-4-ki13.md to describe the starvation mechanism as suspected, not confirmed, and to state KI-13's actual disposition (closed as no longer reproducible) - fix a stale test-count typo in testing-baseline.md Verified: pnpm check green x3, apps/web test:int green, and test:e2e:ci-like green x2 (21/21) after these changes.

…ding - coverage-overlap.mjs: report() now reads the full index and refuses to produce a report (exit 1) when any file failed to collect coverage, instead of silently filtering failures out and reporting on an incomplete set (collect()'s own exit code was fixed in the prior commit; this completes CodeRabbit's ask that report() reject too) - docs/plans/2026-08-23-test-suite-overhaul.md: the plan-wide definition of done said KI-13 must be "moved to Resolved," which conflicts with Phase 4's own decision-rule table permitting an honest re-scope instead; reworded to match - docs/testing-inventory.md: labeled explicitly as a pre-overhaul snapshot (counts predate Phases 1-4's changes) rather than re-deriving every figure, which is Phase 5's own job as that inventory's consumer
package-lock.json was a vestigial artifact from a single npm install that predates the repo's pnpm migration (packageManager, CI, and every workflow already use pnpm exclusively). It declared engines.node >=20, silently drifting from package.json now that it's >=22.18.0. Removed it and gitignored it to stop it from being accidentally recommitted.

Summary
Executes Phases 0-4 of
docs/plans/2026-08-23-test-suite-overhaul.md(plan and inventory already onmainvia prior commits). This is a deliberate off-roadmap insert — called out indocs/STATUS.mdperAGENTS.md's scope-creep rule — and does not move or reopen M10's gate. Phases 5-7 (pruning, de-brittling, guidelines) are explicitly not part of this PR; they're gated on M10 Wave 2's own gate closing, since M10 Wave 2 Phases 5-8 are about to rewrite eight of the components those phases would otherwise touch twice.Phase 0 — baseline. Clean three-run timing protocol (
docs/testing-baseline.md),scripts/classify-test-envs.mjs(35 of 95 web unit files verified node-safe), andpackages/domain's coverage floor recorded.Phase 1 — config-only speed win.
vitest.unit.config.ts's environment split (node by default, jsdom opted back in per file) cuts the unit suite'senvironmenttime 33.5% (88.29s → 58.73s median, zero test content changed, 569/569 tests unchanged).isolate: falsestays off (248-failure finding recorded in-config).playwright.config.tsgains an explicit viewport, trace-on-retry, and CI-only retries.Phase 2 —
@tc/factories(ADR-020). New workspace package: Fishery +@faker-js/fakerleaf factories typed against@tc/contracts,tripDetailFactorycomputing rollups via@tc/domain'srollupCosts(never re-derived), named scenarios, andcommandsFor— the event-sourced command-stream counterpart used by e2e.src/mocks/fixtures.tsis deleted; its 24 callers' imports move to@tc/factorieswith zero body changes.scripts/db-seed.mjsbecomesdb-seed.ts, typed via Node's native TypeScript stripping (zero new dependencies) — deliberately not routed throughcommandsFor, to keep its specific, realistic demo content. Task 2.6 foundrebuildProjections()does a global table rebuild, ruling out removing DB truncation suite-wide as originally assumed; de-truncated the 7 of 11*.int.test.tsfiles verified safe.Phase 3 — e2e reliability. Closes KI-19, KI-21, KI-25. Sign in once via Playwright storageState (24
signInAsDevUsercalls down to 1).dragCardTorewritten to scroll the drop target into view before the drag starts instead of depending on drag-triggered auto-scroll inside a timing budget — removes KI-21's race rather than widening it; verified green 10 consecutive runs idle + 2 more under full CPU saturation. A new"narrow"(1100px) Playwright project runse2e/responsive.spec.ts(5 tests covering every breakpoint-dependent behavior the app has), closing KI-19. A new unauthenticated/api/health/ai-modeendpoint plus PlaywrightglobalSetupmakes the simulated-AI guarantee unconditional, closing KI-25 — verified in both directions (a live-mode server makes the suite refuse to run; the normal path is unaffected). A real, unrelated flake found during verification (m8-make-it-real.spec.ts's delete/undo assertion racing an undo-toast's own text) was fixed too.Phase 4 — KI-13.
scripts/repro-ki13.shreproduces the known saturation condition on demand. Ran against both the pre- and post-Phase-1 config under full CPU saturation: neither reproduced (95/95 files, 569/569 tests green both times). Per the plan's own decision-rule table, KI-13 is closed as no longer reproducible, explicitly not as root-caused — the mechanism was never directly observed this session, and the cold-install condition was not retested (flagged honestly rather than claimed).MoneyInput.test.tsx(KI-13's own canonical slow file),toast.test.tsx, andLocationInput.test.tsxnow useuserEvent.setup({ delay: null }), removing a real per-keystrokesetTimeoutuserEventschedules by default.One new issue filed, not fixed: KI-28, a distinct e2e flake (a trip-actions menu item briefly outside the viewport) found during final verification — unrelated to this PR's four target KIs, documented rather than silently absorbed.
