+**Do not edit this file.** Agents must never add, remove, or reword anything here. If a change seems needed, say so and let a human do it.
+
+## Ask before testing
+
+When asked to review code or build a feature, do not run the test suite and do not write new tests. Make the change, report it, then ask the user whether tests should be added — describing the tests you have in mind — and wait for the user to confirm.
+
+Two reasons this matters here: the suite takes minutes, and `tests/.snapshots/success.txt` plus the tally in `tests/Visual/Parallel.php` encode the whole suite's result, so a single added test breaks both.
+
+Once the user confirms:
+
+```bash
+composer test:unit         # fast, excludes the visual group
+composer test:integration  # visual and snapshot tests
+composer test              # everything CI runs, in CI's order
+composer update:snapshots  # only when a test was added or removed
+```
+
+## TIA scenario tests
+
+`tests/Features/Tia/*` scaffold a throwaway git project, run a real `pest` subprocess against it, and diff the TIA graph it wrote. They exist because TIA's contract is about what a run *writes* — replay, branch keys, and the COMPLETE / RESULTS-ONLY / HARD-SUPPRESSED tiers are invisible to ordinary assertions, and every case used to be measured by hand against a playground app.
+
+Add one whenever a change touches branch resolution, replay, filtered mode, or the write tiers. How:
+
+- `Project::make('master')` scaffolds; `seed('master')` writes a graph and sentinels every cached result (`time=9.999`, `assertions=42`) so any rewrite shows up.
+- `$project->pest('--tia', …)` runs it; `$project->delta()` compares against that snapshot. `writtenCount()` is the discriminator — `0` means "replayed", not "wrote the same values". `mutateGraph()` bends one entry; overlays in `tests/Fixtures/Tia/overlays/<name>/` supply a different `tests/Pest.php`.
+- Keep expectations driver-independent: a cold recording run needs pcov/xdebug and behaves differently without one. Seed a graph instead of recording one.
+
+Run them by file (a directory argument finds nothing) or by `--filter`:
+
+```bash
+php bin/pest tests/Features/Tia/PartialRunWriteTier.php
+```

+# TIA write-tier conformance — plan
+
+Baseline sweep: **147 cases, 144 PASS / 2 FAIL / 1 SKIP** against `dev-fix/tia-filtered` (`db70017`)
+on `playground/laravel` with pcov enabled.
+
+This file records (1) what is left to fix, and (2) the full case matrix with the target
+outcome for every row, so the sweep can be re-run as a conformance check after the fixes land.
+
+---
+
+## Part 1 — What's left
+
+### 1. `--parallel` silently under-records `edges` (G12, I5) — **high**
+
+Any `--tia --parallel` complete run writes `files=4` where sequential writes `files=25`. Only
+`app/**` and blade views survive; every `config/`, `routes/`, `bootstrap/` edge and every test
+self-edge is lost. A `routes/web.php` edit that sequential TIA catches, parallel TIA reports as
+`No affected tests found`.
+
+Root cause — `src/Restarters/PcovRestarter.php:33`:
+
+```php
+if (! Tia::isEnabledForRun($arguments)) {
+    return;
+}
+```
+
+`Tia::isEnabledForRun()` (`src/Plugins/Tia.php:275-288`) returns true only for `--tia` in argv or
+the `PEST_TIA` env flag. A paratest worker's argv carries neither, so workers never re-exec with
+`-d pcov.directory=<projectRoot>` and record under pcov's empty default scope.
+
+Proven both directions:
+- `PEST_PCOV_RESTARTER_RESTARTED=1 pest --tia` (sequential, restart suppressed) reproduces
+  `files=4` with edge sets identical to the parallel graph.
+- `PEST_TIA=1 pest --parallel` restores the full `files=25` graph. **Working workaround today.**
+
+Coverage config is irrelevant: widening `phpunit.xml` `<include>` to `app|config|routes|bootstrap|tests`
+still yields `files=4`.
+
+Sticky, not just per-run: `pest --tia --filtered --parallel` re-records only the affected test
+through a worker and strips that entry's edges from an otherwise-healthy sequential graph, so one
+parallel run degrades a good graph incrementally.
+
+**Fix direction:** propagate the TIA-enabled decision into workers (e.g. set `PEST_TIA` in the
+worker env, or have the parent stamp a recording global the restarter also consults) so
+`PcovRestarter` restarts them. Then assert `edges` equivalence between sequential and parallel.
+
+### 2. Deleted test file with a cached failure wedges `--filtered` forever (I9) — **high**
+
+Expected a WARN and a full-suite fallback. Actual: `--filtered` selects the phantom file, runs
+nothing, exits **0 green**, on every subsequent invocation.
+
+Root cause — `src/Plugins/Tia/Graph.php:1523-1525`:
+
+```php
+if ($real === false) {
+    $real = $path;
+}
+```
+
+`relative()` falls back to the raw path when `realpath()` fails, so a deleted-but-in-project test
+file is never "unlocated", `Graph::hasUnlocatedTestsToRerun()` never fires, and the WARN branch at
+`src/Plugins/Tia.php:982-986` is unreachable for the deletion case. `pruneMissingTests()` only runs
+under `--fresh`, so nothing clears it.
+
+**Fix direction:** distinguish "path could not be resolved" from "path resolved outside the root" in
+`relative()`, or have `hasUnlocatedTestsToRerun()` stat the file directly.
+
+### 3. `--coverage-text` does not disable filtered mode (I8) — **low**
+
+`coverageReportActive()` (`src/Plugins/Tia.php:1705-1710`) reads only Pest's own `--coverage`, so
+raw PHPUnit coverage flags (`--coverage-text`, `--coverage-html`, `--coverage-clover`, …) leave
+filtered mode on. `Tia::COVERAGE_FLAGS` at `:113-115` already enumerates them — that list is not
+consulted here.
+
+### 4. `--coverage` narrows edges like parallel does — **medium, needs triage**
+
+`pest --tia --coverage` prints `fresh graph (recording coverage baseline)` even when a graph
+exists, and writes `Feature/ExampleTest` with 2 files instead of 16, dropping self-edges. Same
+observable shape as G12, likely a different mechanism (piggyback collector scoped by
+`phpunit.xml <include>` rather than the pcov-restarted recorder). Theme: **edges silently narrow to
+`app/**` whenever recording does not go through the pcov-restarted TIA recorder.** Confirm whether
+these are one fix or two.
+
+### 5. Smaller items
+
+| Item | Where | Note |
+|---|---|---|
+| Warning/deprecation recorded as `status=0` | write path | Codes `6` and `4` appear unreachable; risky/skipped/incomplete record faithfully |
+| Complete non-TIA runs write edge-less results | `src/Plugins/Tia.php:1645`, `:638` | Guard is `! $complete && ! knowsTest()`; complete bypasses it and `markKnownTestFiles` stays false. Inert — replay guards on the same predicate at `:360` — but inflates `n` |
+| SIGINT never reaches the suite | `PcovRestarter` re-exec | Parent ignores it; the child holds PHPUnit's handler. CI `timeout`/Ctrl-C will not stop a run |
+| Structural drift never announced sequentially | `src/Plugins/Tia.php:1178-1181` | `enterRecordMode()` prints a bare `Running in TIA mode.`; `renderFreshGraph()` (`fresh graph (composer.lock changed)`) only runs under `--parallel` or coverage piggyback |
+| ~~Replay clobbers cached `time`~~ | write path | **Struck in phase four — does not reproduce**, sequentially or in parallel. Both write paths route through `resultTime()`; a replay with every cached `time` sentinelled writes nothing |
+| ~~`pest --parallel` without `--tia` writes nothing~~ | G3, G6 | **Closed in phase four.** Workers flush their results through `requestWorkerResults()`, so a parallel run refreshes and prunes exactly like the sequential run of the same command |
+| ~~`--tia --parallel --filter`/`--shard` record nothing~~ | G2, G8 | **Closed in phase four** (partial parity landed first, complete parity with the row above) |
+| `--min=50` without `--coverage` is a silent no-op | — | — |
+| `pest --repeat=2` is not a Pest option | J11 | Case unrunnable as written; drop it or add the option |
+
+### 6. Test-harness gaps to close before re-running
+
+- The playground has no `UsesClass`, `->note()`, `->flaky()`, `->issue()`, `->pr()`, `->ticket()` or
+  `->assignee()` annotations, so **C19, C23–C28, C37–C39 matched zero tests** and their
+  graph-invariant assertions proved nothing. Add annotated fixtures to make those rows load-bearing.
+- Use **sentinel patching** (rewrite every cached entry to `time=9.999 assertions=42`, then see which
+  entries get overwritten) as the discriminator. It is the only way to tell "wrote identical values"
+  from "wrote nothing". A canary test absent from `edges` is unreliable under `--filter` because it
+  never matches the filter and so never runs.
+- `--tia` on a clean green tree can never cache a failure (unchanged tests replay rather than
+  execute); seeding one requires `--fresh` or an env-driven flaky fixture.
+- Comment-only edits to a test file are **not** changes (AST-level hashing). Use semantic edits.

+# TIA deep audit — phase five
+
+## Your task
+
+Phases one through four fixed the defects that were *reported*. This phase is the opposite shape: go
+looking. Read TIA's read/write path adversarially, find what is wrong or fragile, and leave behind a
+scenario suite that covers the edges nobody has exercised yet.
+
+Two deliverables, both required:
+
+1. **A ranked findings list.** Every finding needs a *reproduction*, not a reading of the code. A
+   finding you cannot reproduce is a hypothesis — say so and rank it separately.
+2. **New scenario tests** in `tests/Features/Tia/*`, covering the edges you probed. Rows that pass go
+   in the repo (they are the regression net). Rows that fail stay in your scratchpad until the fix
+   lands — **never commit a red test.**
+
+Work in passes, and **report between passes** rather than at the very end:
+
+- **Pass A** — reproduce the leads in Part 3 below. Report which are real.
+- **Pass B** — your own hunt: the invariants in Part 2, attacked with inputs nobody tried.
+- **Pass C** — fixes, smallest first, each with the row that pins it.
+
+Fix what is clearly a defect with an obvious correct answer. **Stop and ask** when the fix is a
+behaviour *choice* (what should TIA do when two runs race for one graph?) — those are Nuno's calls,
+and a reproduction with a crisp yes/no question is worth more than a guessed fix.
+
+---
+
+## Part 1 — The harness
+
+### 1.1 What TIA is
+
+Test Impact Analysis. `pest --tia` records a dependency graph (test file → source files it touched)
+plus a per-branch baseline of results, then on later runs replays the tests whose dependencies did not
+change. State lives in a per-project dir under `~/.pest/tia/`; `graph.json` is the whole thing.
+
+Source of truth: `src/Plugins/Tia.php` (the plugin, ~1900 lines) and `src/Plugins/Tia/Graph.php` (the
+graph model + read/write API). Supporting: `src/Plugins/Tia/ChangedFiles.php` (git), `Fingerprint.php`
+(environment/structure hashing), `State.php` (the state dir).
+
+Read `PLAN.md`, `PLAN_PHASE_TWO.md`, `PLAN_PHASE_THREE.md`, `PLAN_PHASE_FOUR.md` first — in that
+order. They carry the history, the tier contract, and the decisions already made. Struck-through rows
+are fixed; do not re-report them.
+
+### 1.2 The scenario harness
+
+`tests/Features/Tia/*` scaffold a throwaway git project into a temp dir, run a **real `pest`
+subprocess** against it, and diff the graph it wrote. Everything lives in `tests/Fixtures/Tia/`:
+
+| Class | What it gives you |
+|---|---|
+| `Project` | `make(branch, overlay:)`, `withoutGit()`, `seed(branch, sentinel:, failing:)`, `seedFor($root, …)`, `pest(...$args)`, `pestWithEnvironment($dir, $env, ...$args)`, `pestIn($dir, ...)`, `write($rel, $contents)`, `path($rel)`, `graph()`, `branchKeys()`, `graphDir()`, `graphExists()`, `snapshot()`, `delta()`, `mutateGraph(fn)`, `addBaseline($branch)`, `worktree($branch)`, `destroy()`, `destroyAll()`, `SEQUENTIAL_AND_PARALLEL` |
+| `GitRepo` (`$project->git()`) | `switchTo($b, new:)`, `rename($from, $to)`, `detach()`, `config($k, $v)`, `addOrigin()`, `removeOrigin()`, `setOriginHead($b)`, `unsetOriginHead()`, `worktree()`, `sha()`, `branchNames()` |
+| `GraphDelta` (`$project->delta()`) | `writtenCount()`, `added()`, `removed()`, `branchKeys()`, `baselineUntouched($b)`, `shaMoved()`, `treeMoved()`, `edgesMoved()`, `filesMoved()`, `fingerprintMoved()`, `structureMoved()`, `isResultsOnly()`, `isHardSuppressed()`, `summary()` |
+| `PestResult` (returned by `pest()`) | `replayed()`, `uncached()`, `affected()`, `tally()`, `output`, `exitCode`, `describe()` |
+
+The fixture app is 3 test files / **6 tests** (`Project::TOTAL_TESTS`); `Project::EDGES` and
+`Project::TESTS` describe the graph `seed()` writes. `Project::testId($file, $description)` builds a
+result key. Overlays in `tests/Fixtures/Tia/overlays/<name>/` supply a different `tests/Pest.php` —
+that is how you configure `pest()->tia()->…` for a scenario.
+
+**If the fixture cannot express your case, extend the fixture.** A new `GitRepo` verb or a new overlay
+is a legitimate part of the deliverable — several findings below need one. Do not water down a
+scenario to fit the current helpers.
+
+### 1.3 The sentinel discriminator — read before writing any assertion
+
+`seed()` writes a graph **and then rewrites every cached result to `time=9.999`, `assertions=42`**
+(only where assertions are non-zero — risky/skipped/incomplete statuses are *derived* from "performed
+no assertions", so falsifying those would rewrite the status on replay), then snapshots. Therefore:
+
+- `$delta->writtenCount()` is the only reliable way to tell **"replayed"** from **"executed and wrote
+  back the same values"**. `0` means nothing was written.
+- `isResultsOnly()` = no structure moved, no `sha`/`tree` movement, nothing added or removed.
+- `isHardSuppressed()` = the graph is byte-identical.
+- A replayed suite reports inflated assertion counts (6 tests × 42). That is the sentinel, not a bug.
+
+The three write tiers, unchanged since phase two:
+
+- **COMPLETE** — may change everything.
+- **RESULTS-ONLY** — may change only `baselines[<branch>].results` for tests that ran; never removes
+  an entry, never adds a result for a test file absent from `edges`, never touches
+  `sha`/`tree`/`edges`/`files`/`fingerprint`.
+- **HARD-SUPPRESSED** — may change nothing.
+
+### 1.4 Running them
+
+They are in the `integration` group (`tests/Pest.php`), so `composer test:unit` skips them. **A
+directory argument finds nothing** — pass files, space-separated, as separate argv entries:
+
+```bash
+PAO_DISABLE=1 php84 bin/pest tests/Features/Tia/DefaultBranchReplay.php tests/Features/Tia/DefaultBranchResolution.php \
+  tests/Features/Tia/DefaultBranchWriteTier.php tests/Features/Tia/PartialRunWriteTier.php \
+  tests/Features/Tia/CompleteRunWriteTier.php tests/Features/Tia/FilteredMode.php
+
+PAO_DISABLE=1 php   bin/pest <same list>
+```
+
+**Both interpreters must be green.** `php84` is 8.4.x with **no pcov** — that is what CI has
+(`.github/workflows/tests.yml` sets `coverage: none`). `php` is 8.5.x with pcov — that is the dev
+machine. Any assertion that depends on a coverage driver passes locally and fails in CI. Concretely:
+
+- A **cold recording run writes no graph at all** without pcov/xdebug (it prints `Running in TIA mode,
+  however TIA is skipped as it needs ext-pcov or Xdebug`). **Seed a graph, never record one**, unless
+  the driver *is* the point of the row.
+- A **PHP source file edit** driverless triggers `Detected PHP source changes but no coverage driver
+  is available` → full suite, `affected=0`. Edit *test* files, not `app/` files.
+
+`PAO_DISABLE=1` is mandatory on every pest invocation and every probe: `laravel/pao` emits JSON under
+agents and corrupts the captured output.
+
+Baseline before you touch anything: **72 passed** on both interpreters, at `HEAD` plus the phase-four
+working-tree changes. If that number does not reproduce, stop and say so.
+
+### 1.5 Measure before you assert
+
+Never guess an expectation from reading the code. Probe first, in your scratchpad:
+
+```php
+<?php
+require '/Users/nunomaduro/Work/projects/pestphp/pest/vendor/autoload.php';
+use Tests\Fixtures\Tia\Project;
+
+$p = Project::make('master');
+$p->seed('master');
+$p->git()->switchTo('feature-x', new: true);
+$r = $p->pest('--tia');
+printf("tally=[%s] keys=[%s] %s\n", $r->tally(), implode(',', $p->branchKeys()), $p->delta()->summary());
+$p->destroy();
+```
+
+`PAO_DISABLE=1 php probe.php`. One project per scenario; always `destroy()`; `Project::destroyAll()`
+at the end. Run every probe on **both** interpreters before believing it.
+
+### 1.6 Ground rules
+
+- **Do not** run `composer test`. It takes minutes and you do not need it.
+- **Do not** run `composer update:snapshots`. `tests/.snapshots/success.txt` and the tally in
+  `tests/Visual/Parallel.php` encode the whole suite's result, so every row you add breaks them.
+  That is expected — **report that they need regenerating and let Nuno run it.**
+- **Do not commit.** Leave the tree dirty.
+- **Do not touch the playground's `vendor/`.** If a finding truly needs the playground (25 real tests,
+  real timings), say so and ask — syncing it is a manual step Nuno owns.
+- Run `vendor/bin/phpstan analyse <the files you touched> --memory-limit=-1 --no-progress` and
+  `vendor/bin/pint <the files you touched>` before reporting. **Scope both to files you changed** —
+  Nuno edits `src/` live, and a repo-wide fixer will revert his work.
+- The fixture projects **hardlink `src/`**. If you edit `src/` while a scenario run is in flight,
+  those rows go red for no reason. Finish the edit, then run.
+- Keep scratch probes out of the repo.
+- **Never weaken an existing assertion to make something pass.** If an existing row contradicts your
+  fix, that is a finding: report the contradiction and ask.
+
+---
+
+## Part 2 — The invariants to attack
+
+These are the properties TIA is supposed to have. Each one is a place to hunt: construct the input
+that breaks it.
+
+1. **Parity.** `pest <args>` and `pest --parallel --processes=N <args>` must leave the **same graph**
+   and reach the same tally. This is a hard rule from Nuno — sequential and parallel must *always*
+   agree. `Project::SEQUENTIAL_AND_PARALLEL` is the dataset that encodes it; consider making every
+   new write-path row use it. Vary `--processes` (1, 2, 8 — more processes than test files).
+2. **The tiers hold.** Every command lands in exactly one of COMPLETE / RESULTS-ONLY /
+   HARD-SUPPRESSED, and stays inside it. Combinations are where this frays: `--fresh --parallel
+   --filter`, `--bail --shard`, `--filtered` plus an explicit path, `--tia --no-tia`, `--retry`.
+3. **Replay is faithful.** A replayed test reports the same status, message, time and assertion count
+   as the recorded run — and replay itself writes nothing. Statuses beyond pass/fail are the soft
+   spot: skipped, incomplete, risky, notice, deprecation, warning, todo, and a test that failed with a
+   multi-line message.
+4. **Reads never write.** No read path may mint a baseline key, move a `sha`, or create the state dir.
+   A project that has never run TIA must gain nothing from a plain `pest` run.
+5. **A branch never corrupts another branch's baseline.** Writes land on the branch that ran, and
+   only there. Reads may *layer* the default branch under the current one (phase four, B1) — but that
+   layering must not leak into a write.
+6. **Nothing is unbounded.** Baseline keys, `files`, `edges`, worker partials, state files: something
+   must eventually reclaim them, or the graph grows forever.
+7. **A hostile state dir cannot break a run.** Corrupt, truncated, empty, wrong-schema, read-only,
+   absent, or *someone else's* `graph.json` — the suite still runs and exits on the tests' merit.
+8. **Git shapes are all handled.** Detached HEAD (read-only, per phase four B2), worktrees, no commits
+   yet, no `origin`, no `origin/HEAD`, submodules, a repo whose root is above the pest project (that
+   one panics deliberately — `TiaRequiresRepositoryRoot`), renamed branches, deleted branches.
+
+---
+
+## Part 3 — Leads to reproduce first (Pass A)
+
+These came out of reading the phase-four diff. **Each is a hypothesis, not a finding** — several may
+turn out to be fine. Reproduce or refute each, in order, and report the measured delta either way.
+
+### L1 — the per-entry fallback may resurrect a pruned or deleted test · **highest value**
+
+Phase four made `Graph::baselineFor()` layer the branch's results **over** the default branch's. Two
+consequences worth probing:
+
+- `pruneStaleResults()` unsets an entry from `baselines[branch].results`. The very next read layers the
+  **fallback's** entry for that same test id back in. So a delete may not stick from a branch's point
+  of view.
+- `hasUnlocatedTestsToRerun()` returns true when a *failing* cached result names a file that no longer
+  exists on disk — and that forces a **full suite**. If a feature branch deletes a test file that
+  fails on the default branch, the merged read still carries master's entry pointing at the now-absent
+  file. Suspected symptom: **that branch runs the full suite forever.**
+
+Probe: seed master with a failing test (`seed('master', failing: [...])`), branch off, delete the test
+file that holds it, run `--tia`, and compare `replayed`/`uncached`/`affected` against the same shape
+where the failure is on the branch instead. Then the mirror case with a green deleted test.
+
+### L2 — environment drift clears one branch's results and the fallback serves them right back
+
+`reconcileFingerprint()` on environmental drift calls `$graph->clearResults($this->branch)` and warns
+`results dropped, edges reused`. On a feature branch that clears only the *branch's* results — the
+layered read then re-serves the default branch's results, which were recorded under the **old**
+environment. Suspected symptom: the drop is a no-op on any branch that is not the default one.
+
+Probe: `pestWithEnvironment()` to shift whatever `Fingerprint` reads as environmental (check
+`Fingerprint::environmentalDrift()` for the exact keys), on the default branch vs a feature branch,
+and compare what survives.
+
+### L3 — `sha`/`tree` may be taken from a different commit than the results
+
+`baselineFor()` takes `sha` from the branch when non-null and otherwise from the fallback; `tree`
+likewise when the branch's is empty. So a branch can end up computing "what changed since" against the
+**default branch's** recorded sha while reading its own results — or vice versa. Is there a shape where
+that under-reports changed files (a test replays that should have run)? That is the dangerous
+direction: a false replay is a lie about a passing test.
+
+Probe: seed master, commit a test edit on the branch so the shas genuinely differ, and check whether
+the edited test is treated as affected.
+
+### L4 — pruning from merged worker partials
+
+Phase four made a complete `--parallel` run write and prune from merged worker results. The stated
+safety net is that `pruneStaleResults()` only prunes files it saw results for, and that a truncated
+worker sets results-only. Try to defeat it: a worker that reports results for a test file it did not
+finish. Candidate shapes — a fatal error mid-file (not an assertion failure), `exit()` inside a test,
+an uncaught error in an `afterEach`, a test that kills its own process, `--stop-on-failure` variants,
+`--processes` greater than the number of test files.
+
+### L5 — two runs racing for one `graph.json`
+
+`State::write()` has no locking. Two pest processes on one project (a watcher plus a manual run, two CI
+jobs sharing a cache dir, `--parallel` where the parent writes while a straggler worker flushes) can
+lose an update or interleave. Probe by launching two `pest --tia` subprocesses concurrently against one
+project and diffing. **This is likely a design decision, not a bug** — if you reproduce a lost update,
+report it as a question (accept last-writer-wins, or lock?), do not invent a locking scheme.
+
+### L6 — a detached HEAD still purges on structural drift
+
+Phase four made a detached HEAD read-only *for writes* (`saveGraph()` refuses). But
+`reconcileFingerprint()` deletes the whole graph on structural drift (`Tia.php`, the
+`state->delete(KEY_GRAPH)` in the structural branch) before any write happens. So `--tia` from a
+detached checkout with a changed `composer.lock` can still wipe the default branch's baseline. Confirm
+it, then ask: should the detached-HEAD guard cover the purge too?
+
+### L7 — statuses that may not round-trip
+
+`PLAN.md` §5 claims warnings and deprecations record as `status=0`, and that codes `6` and `4` look
+unreachable. `Graph::getResult()` maps 0–8 to `TestStatus`. Verify each status end to end: record it,
+replay it, and check the replayed run reports the same thing — including the message, the exit code,
+and whether `shouldRerunStatus()` decides to re-execute it. `failOnRisky` / `failOnSkipped` /
+`displayDetailsOn*` change that decision, so an overlay that flips those config flags is part of this.
+A status that replays as a pass would be the most serious class of bug in TIA.
+
+### L8 — branch-key hygiene
+
+Nothing appears to reclaim baseline keys. Probe: create and delete 5 branches, rename one
+(`GitRepo::rename()`), and check what `branchKeys()` holds afterwards. Also try names that stress the
+JSON keying: `feature/x/y` (already covered), a name differing from another only in case (macOS is
+case-insensitive — does the key match the ref?), a name with a space or a unicode character, a branch
+literally called `HEAD`, and a very long name. Then: is unbounded growth acceptable, or does this need
+a cap / GC? Ask rather than build.
+
+### L9 — `soleRecordedBranch()` as a fallback source
+
+When config, CI env and git all fail to name a default branch, resolution falls back to "the only
+branch in the graph". If that sole key was minted by a *narrowed* run on a feature branch (which phase
+four's B1 made a live possibility), the fallback now names a feature branch, and every other branch
+layers **its** results underneath. Probe: `withoutGit()` or `removeOrigin()` + no config, with a graph
+whose only key is `feature-x`.
+
+### L10 — the state dir as an adversary
+
+Beyond corrupt JSON (fixed in phase four by deleting it): a valid-JSON graph with `schema: 2`; a graph
+whose `files` and `edges` disagree; `results` entries with a `file` pointing outside the project root
+or at an absolute path from another machine; a `graph.json` that is a directory; a state dir with no
+write permission; `$HOME` unset. Each should degrade to "run the tests", never crash and never write
+garbage.
+
+---
+
+## Part 4 — Reporting
+
+**Between passes**, not just at the end. Per finding:

+# TIA defect sweep — phase four
+
+## Your task
+
+Five defects in TIA's read/write path, found while building the repo's TIA scenario suite. One is
+confirmed and load-bearing (**B1**); four need a decision before a fix (**B2**–**B5**).
+
+Work **one bug at a time, in order**, and for each:
+
+1. **Reproduce it as a repo test first.** The reproduction is the deliverable even when the fix is
+   deferred — a red test that pins the exact symptom is worth more than a prose report. Do not commit
+   a red test to the suite; keep it in a scratch file until the fix lands (see Part 1.4).
+2. Confirm the measured numbers in this file still hold. They were taken at commit `4d3d0105` plus
+   the two uncommitted changes described in Part 2. If a number has moved, say so and stop.
+3. Fix, then re-run **the whole `tests/Features/Tia/*` set on two interpreters** (Part 1.3).
+4. **HARD STOP after B1.** Report the diff and wait — B1's fix changes `Graph`'s read semantics for
+   every caller, and Nuno wants to see it before B2–B5 pile on top.
+
+Per `CLAUDE.md`: do not run `composer test`, and do not regenerate snapshots unless told. Do not
+commit. Do not touch the playground's `vendor/`.
+
+---
+
+## Part 1 — The harness
+
+### 1.1 What exists
+
+`tests/Features/Tia/*` scaffold a throwaway git project into a temp dir, run a **real `pest`
+subprocess** against it, and diff the TIA graph it wrote. Everything lives in
+`tests/Fixtures/Tia/`:
+
+| Class | What it gives you |
+|---|---|
+| `Project` | `make(branch, overlay:)`, `withoutGit()`, `seed(branch, sentinel:, failing:)`, `pest(...$args)`, `pestWithEnvironment($dir, $env, ...$args)`, `pestIn($dir, ...)`, `write($rel, $contents)`, `graph()`, `branchKeys()`, `graphDir()`, `graphExists()`, `snapshot()`, `delta()`, `mutateGraph(fn)`, `addBaseline($branch)`, `worktree($branch)`, `destroyAll()` |
+| `GitRepo` (`$project->git()`) | `switchTo($b, new:)`, `rename($from, $to)`, `detach()`, `config($k, $v)`, `addOrigin()`, `removeOrigin()`, `setOriginHead($b)`, `unsetOriginHead()`, `worktree()`, `sha()`, `branchNames()` |
+| `GraphDelta` (`$project->delta()`) | `writtenCount()`, `added()`, `removed()`, `branchKeys()`, `baselineUntouched($b)`, `shaMoved()`, `treeMoved()`, `edgesMoved()`, `filesMoved()`, `fingerprintMoved()`, `structureMoved()`, `isResultsOnly()`, `isHardSuppressed()`, `summary()` |
+| `PestResult` (returned by `pest()`) | `replayed()`, `uncached()`, `affected()`, `tally()`, `output`, `exitCode`, `describe()` |
+
+The fixture app is 3 test files / **6 tests** (`Project::TOTAL_TESTS`), with `Project::EDGES` and
+`Project::TESTS` describing the graph `seed()` writes. `Project::testId($file, $description)` builds
+a result key.
+
+### 1.2 The sentinel discriminator — read this before writing an assertion
+
+`seed()` writes a graph **and then rewrites every cached result to `time=9.999`,
+`assertions=42`** (non-zero assertion counts only — risky/skipped/incomplete statuses are *derived*
+from "performed no assertions", so falsifying those would rewrite the status on replay), and takes a
+snapshot. Therefore:
+
+- `$delta->writtenCount()` is the only reliable way to tell **"replayed"** from **"executed and wrote
+  back the same values"**. `0` means nothing was written.
+- `isResultsOnly()` = no structure moved, no `sha`/`tree` movement, nothing added or removed.
+- `isHardSuppressed()` = the graph is byte-identical.
+
+Tiers, unchanged since phase two: **COMPLETE** may change everything · **RESULTS-ONLY** may change
+only `baselines[<branch>].results` for tests that ran, never removing an entry, never adding a result
+for a test file absent from `edges`, never touching `sha`/`tree`/`edges`/`files`/`fingerprint` ·
+**HARD-SUPPRESSED** may change nothing.
+
+### 1.3 Running them
+
+They are in the `integration` group (`tests/Pest.php:22`), so `composer test:unit` skips them. A
+**directory argument finds nothing** — pass files:
+
+```bash
+F="tests/Features/Tia/DefaultBranchReplay.php tests/Features/Tia/DefaultBranchResolution.php \
+   tests/Features/Tia/DefaultBranchWriteTier.php tests/Features/Tia/PartialRunWriteTier.php \
+   tests/Features/Tia/CompleteRunWriteTier.php tests/Features/Tia/FilteredMode.php"
+
+PAO_DISABLE=1 php84 bin/pest $F     # 8.4.23, NO pcov — this is what CI has
+PAO_DISABLE=1 php   bin/pest $F     # 8.5.8, pcov — this is what your machine has
+```
+
+**Both must be green.** `.github/workflows/tests.yml` sets `coverage: none`, so any assertion that
+depends on a coverage driver fails in CI while passing locally. Two tests were already caught by
+this. Concretely: a **cold recording run writes no graph at all** without pcov/xdebug (it prints
+`Running in TIA mode, however TIA is skipped as it needs ext-pcov or Xdebug`), and a **PHP source
+file edit** triggers `Detected PHP source changes but no coverage driver is available` → full suite,
+`affected=0`. Seed a graph instead of recording one, and edit *test* files rather than `app/` files,
+unless the point of the row is the driver itself.
+
+### 1.4 Measure before you assert
+
+Do not guess expectations from reading the code — every number in Part 3 came from a scratch probe.
+The pattern (put it in your scratchpad, not in the repo):
+
+```php
+<?php
+require '/Users/nunomaduro/Work/projects/pestphp/pest/vendor/autoload.php';
+use Tests\Fixtures\Tia\Project;
+
+$p = Project::make('master');
+$p->seed('master');
+$p->git()->switchTo('feature-x', new: true);
+$r = $p->pest('--tia');
+printf("tally=[%s] keys=[%s] %s\n", $r->tally(), implode(',', $p->branchKeys()), $p->delta()->summary());
+$p->destroy();
+```
+
+`PAO_DISABLE=1 php probe.php`. One project per scenario; always `destroy()`.
+
+---
+
+## Part 2 — What the code looks like right now
+
+Phase three landed default-branch resolution: `ChangedFiles::defaultBranch()`, the
+`pest()->tia()->defaultBranch()` config surface, `Graph::setFallbackBranch()` + `?string
+$fallbackBranch = null` on the seven read methods, and `Tia::resolveFallbackBranch()`
+(`Tia.php:~1776`) resolving **config → CI env (`CiDefaultBranch`) → git (`origin/HEAD`, then
+`init.defaultBranch` if the branch exists) → `soleRecordedBranch()`**, failing loudly when nothing
+can name it.
+
+On top of that, **two uncommitted changes** you will see in `git diff`:
+
+1. `TIA_RESULTS_ONLY` global — a *partial* parallel run with an existing graph now purges stale
+   worker partials, sets the global, and workers flush their results through the existing
+   `flushWorkerReplay()` / `mergeWorkerReplayPartials()` path; the parent writes them with
+   `complete: false`. Gated on a graph already existing, so a TIA-less project still creates no
+   baseline dir. This gave `--parallel --filter` parity with sequential — **and, per B1, handed it
+   the shadowing bug too.**
+2. `loadGraph()` emits `WARN The dependency graph could not be read — it will be rebuilt.` once per
+   parent process when `graph.json` exists but will not decode. Previously silent.
+
+62 scenario tests cover this and pass on both interpreters.
+
+---
+
+## Part 3 — The defects
+
+### B1 — a thin baseline key permanently shadows the default-branch fallback · **confirmed, priority 1**
+
+**Symptom.** Any *narrowed* run on a new branch (`--filter`, `--group`, a path, `--bail`, `--shard`,
+and now `--parallel --filter`) writes a baseline key holding only the tests that ran. From then on
+`--tia` on that branch reads that thin key instead of falling back to the default branch, so
+everything else is uncached — **one full suite per branch, forever**, which is the exact cost
+issue [#1823](https://github.com/pestphp/pest/issues/1823) was about, re-entering through a side door.
+
+**Measured** (fixture: 6 tests, graph seeded on `master`):
+
+```
+switch -c feature-x; pest --filter="adds two numbers"
+  → keys=[master,feature-x]        (feature-x holds 1 result)
+pest --tia
+  → 6 passed (6 assertions, 5 uncached, 1 replayed)      ← want: 6 replayed, 0 uncached
+
+same via: pest --parallel --processes=2 --filter="adds two numbers"   → identical
+```
+
+**Where.** `src/Plugins/Tia/Graph.php::baselineFor()` (~line 814):
+
+```php
+if (isset($this->baselines[$branch]))                                        return $this->baselines[$branch];
+if ($branch !== $fallbackBranch && isset($this->baselines[$fallbackBranch])) return $this->baselines[$fallbackBranch];
+```
+
+The fallback is all-or-nothing: it fires only when the branch has **no** key at all. The key itself
+is minted by `Graph::setResult()` → `ensureBaseline($branch)` (~599 / ~829), reached from
+`Tia::snapshotTestResults()` on partial runs.
+
+**Reproduction to add** (`tests/Features/Tia/DefaultBranchReplay.php`):
+
+```php
+test('a narrowed run on a new branch does not cost the fallback', function (): void {
+    $project = Project::make('master');
+    $project->seed('master');
+
+    $project->git()->switchTo('feature-x', new: true);
+    $project->pest('--filter=adds two numbers');
+
+    $result = $project->pest('--tia');
+
+    expect($result->replayed())->toBe(Project::TOTAL_TESTS, $result->describe())
+        ->and($result->uncached())->toBe(0, $result->describe());
+})->skipOnWindows();
+```
+
+Add the `--parallel --processes=2 --filter=…` variant as a second row (dataset), since the two write
+paths are different code.
+
+**Fix direction.** Make the fallback **per entry** rather than per baseline: in `baselineFor()`,
+when the branch has its own baseline *and* a distinct fallback baseline exists, return
+`results` = the branch's results **layered over** the fallback's (branch wins per test id), and take
+`sha`/`tree` from the fallback when the branch's are `null`/empty. `baselineFor()` is the single
+funnel for `recordedAtSha()`, `lastRunTree()`, `getResult()`, `getTime()`, `getAssertions()`,
+`testFilesToRerun()` and `hasUnlocatedTestsToRerun()`, so one change covers every reader. An
+alternative — never mint a key from a partial run — is smaller but loses the executed result
+entirely, which regresses the parity just gained.
+
+**Done when.** Both reproduction rows are green on both interpreters, and none of these move:
+
+- `the branch that ran gets its own key and the default branch keeps its baseline` — writes stay on
+  the real branch; the merge must be **read-only** and must not leak into `ensureBaseline()`/`setResult()`.
+- `a declared default branch that does not exist degrades to a full run` — with a fallback that names
+  nothing, a branch's own thin results must still be all you get.
+- `a detached HEAD replays without minting a branch key`, `writes nothing on a second run on the same
+  branch`, `filtered mode finds nothing to do…` (both rows) — a merged read must not make a clean
+  replay start writing.
+- The whole `PartialRunWriteTier.php` / `CompleteRunWriteTier.php` set — tier semantics are unchanged
+  by this fix.
+
+---
+
+### B2 — a partial run on detached HEAD writes into the default branch's baseline · **needs a decision**
+
+**Symptom.** With `HEAD` detached, `Tia::resolveBranch()` (`Tia.php:~1756`) sets
+`$this->branch = $changedFiles->currentBranch() ?? $this->fallbackBranch` — and that branch is used
+for **writes**. A `--tia` run in this state happens to be harmless (a clean replay writes nothing),
+but any run that *executes* tests writes their results into the default branch's baseline.
+
+**Measured.**
+
+```
+seed on master; git checkout --detach; pest --filter="adds two numbers"
+  → keys=[master]   w=1 struct:ok        ← master's baseline rewritten from a detached checkout
+seed on master; git checkout --detach; pest --tia
+  → keys=[master]   w=0                  ← read-only, as intended
+```
+
+**The decision.** `PLAN_PHASE_THREE.md` §2.3 **D3** recommended detached HEAD be *read-only*. If that
+still stands, suppress writes when `currentBranch()` is `null` (a dedicated flag — note
+`resultsOnlyWrites` is **not** enough, it still writes results). If Nuno prefers the current
+behaviour, add a test pinning it and close this out.
+
+**Reproduction** (`tests/Features/Tia/DefaultBranchWriteTier.php`), written for the read-only answer:
+
+```php
+test('a detached HEAD does not write into the default branch baseline', function (): void {
+    $project = Project::make('master');
+    $project->seed('master');
+
+    $project->git()->detach();
+    $project->pest('--filter=adds two numbers');
+
+    $delta = $project->delta();
+
+    expect($delta->baselineUntouched('master'))->toBeTrue($delta->summary())
+        ->and($project->branchKeys())->toBe(['master']);
+})->skipOnWindows();
+```
+
+---
+
+### B3 — an unreadable graph is never repaired on a machine with no coverage driver · **needs a decision**
+
+**Symptom.** A corrupt `graph.json` is now *reported* (Part 2, change 2) but only *rebuilt* when a
+coverage driver is present, because rebuilding means recording. Driverless, the file stays corrupt
+run after run and TIA is silently inert until someone deletes it by hand — while the WARN claims
+`it will be rebuilt`.
+
+**Measured** (`php84`, no pcov):
+
+```
+overwrite graph.json with '{not json'
+run 1: exit=0, 6 passed, file still '{not json'
+run 2: exit=0, 6 passed, file still '{not json'
+headline: "Running in TIA mode, however TIA is skipped as it needs ext-pcov or Xdebug"
+```
+
+**Options.** (a) delete the file when it cannot be decoded, so the next drivered run starts clean and
+the state dir does not carry a permanent landmine; (b) keep the file but reword the WARN when no
+driver is available. (a) is the honest one and costs one `State::delete()`.
+
+**Reproduction** (`tests/Features/Tia/FilteredMode.php`, extending the existing corrupt-graph row):
+
+```php
+expect($result->output)->toContain('The dependency graph could not be read')
+    ->and(file_get_contents($project->graphDir().'/graph.json'))->not->toBe('{not json');
+```
+
+Must pass on **both** interpreters — that is the whole point of the row.
+
+---
+
+### B4 — a complete `--parallel` run writes nothing and prunes nothing · **needs a decision**
+
+**Symptom.** With a graph present and TIA not flagged, a sequential run refreshes results and applies
+the prune; the same run under `--parallel` does neither, because the parent's `ResultCollector` is
+empty (results live in the workers) and workers only flush when they were told to record, replay, or
+— since Part 2's change — results-only for a *partial* run. So parallel CI contributes nothing to the
+cache, and a deleted test's entry survives forever.
+
+**Measured** (graph seeded on `master`, sentinelled):
+
+```
+pest                                  → w=6  +0 -0 struct:ok      (sequential baseline)
+pest --parallel --processes=2         → w=0  +0 -0 struct:ok      ← writes nothing
+delete a test, then:
+pest --parallel --processes=2         → w=0  +0 -0 struct:ok      ← and does not prune (sequential gives -1)
+pest --tia --parallel --processes=2   → w=0                       ← correct: everything replayed
+```
+
+**The decision.** Extending the `TIA_RESULTS_ONLY` mechanism to complete parallel runs is
+mechanically easy, but a *complete* run also prunes, and pruning from merged worker partials is the
+risky half: a worker that dies, or a shard that never ran, would look like "these tests no longer
+exist". If it is done, the prune must key off "every worker reported" and fall back to
+results-only when it cannot prove that. `PLAN.md` §5 lists this as a known gap, not a regression.
+
+**Reproduction** (`tests/Features/Tia/CompleteRunWriteTier.php`) — mirror the two sequential rows
+that already exist (`a complete run prunes a deleted test`, `--no-tia refreshes results…`) with
+`--parallel --processes=2` added, and assert the same deltas.
+
+---
+
+### B5 — G4 ("parallel replay clobbers cached `time`") no longer reproduces · **verify, then correct the record**
+
+**Symptom.** `PLAN_PHASE_THREE.md` §4.6 lists as still-present: *"parallel replay clobbers cached
+`time` on all non-executed tests — `mergeWorkerReplayPartials()` takes `$result['time']` verbatim,
+never routing through `resultTime()`"*. The repo fixture disagrees: after a parallel replay the
+sentinelled `time=9.999` / `assertions=42` survive on every non-executed test.
+
+**Measured.** `a parallel run merges worker results into the parent baseline` edits one test file,
+then runs `--tia --parallel --processes=2`: `2 affected, 4 replayed, w=2`. If replayed times were
+being clobbered, `w` would be `6`.
+
+**Why the record may be stale.** `flushWorkerReplay()` (`Tia.php:~1286`) already applies
+`resultTime()` **worker-side** before writing the partial, so the parent's verbatim read is reading
+values that were already corrected.
+
+**What to do.** Either find a shape where it still reproduces (the playground has 25 tests and real
+timings; the fixture has 6 and may be too small), or confirm it is fixed and strike it from §4.6.
+Add a direct row either way:
+
+```php
+test('a parallel replay keeps the recorded time of tests that did not run', function (): void {
+    $project = Project::make('master');
+    $project->seed('master');
+
+    $project->pest('--tia', '--parallel', '--processes=2');
+
+    $delta = $project->delta();
+
+    expect($delta->writtenCount())->toBe(0, $delta->summary())
+        ->and($delta->isResultsOnly())->toBeTrue($delta->summary());
+})->skipOnWindows();
+```
+
+---
+
+## Part 4 — Reporting
+
+Per bug: **reproduced (yes/no)** with the measured delta, **fixed (yes/no/deferred)**, and the test
+that now pins it. Close with:
+
+1. Whether all `tests/Features/Tia/*` are green on **both** `php84` (no pcov) and `php85` (pcov).
+2. Which of B2–B5 still need Nuno's decision, phrased as a yes/no question each.
+3. Whether `tests/.snapshots/success.txt` and the `tests/Visual/Parallel.php` tally now need

+   asked.**

+# TIA deep audit — phase six
+
+## Your task
+
+Phase five went looking rather than fixing what was reported, and found nine defects in the
+**read/write path and the state dir**. All nine are fixed and pinned by rows in the repo. It stopped
+there deliberately: roughly half of TIA was never opened. Phase six is that other half.
+
+Two deliverables, both required:
+
+1. **A ranked findings list.** Every finding needs a *reproduction*, not a reading of the code. A
+   finding you cannot reproduce is a hypothesis — say so and rank it separately.
+2. **New scenario tests** in `tests/Features/Tia/*`. Rows that pass go in the repo (they are the
+   regression net). Rows that fail stay in your scratchpad until the fix lands — **never commit a red
+   test.**
+
+Work in passes, and **report between passes** rather than at the very end:
+
+- **Pass A** — reproduce the leads in Part 3. Report which are real.
+- **Pass B** — your own hunt: the invariants in Part 2, attacked with inputs nobody tried.
+- **Pass C** — fixes, smallest first, each with the row that pins it.
+
+Fix what is clearly a defect with an obvious correct answer. **Stop and ask** when the fix is a
+behaviour *choice* — those are Nuno's calls, and a reproduction with a crisp yes/no question is worth
+more than a guessed fix.
+
+---
+
+## Part 1 — Where things stand
+
+### 1.1 What TIA is
+
+Test Impact Analysis. `pest --tia` records a dependency graph (test file → source files it touched)
+plus a per-branch baseline of results, then on later runs replays the tests whose dependencies did not
+change. State lives in a per-project dir under `~/.pest/tia/`; `graph.json` is the whole thing.
+
+Source of truth: `src/Plugins/Tia.php` (the plugin) and `src/Plugins/Tia/Graph.php` (the graph model +
+read/write API). Supporting: `ChangedFiles.php` (git), `Fingerprint.php` (environment/structure
+hashing), `Storage.php` / `FileState.php` (the state dir), `ResultCollector.php` (what a run observed),
+`Recorder.php` + `CoverageCollector.php` (how edges are recorded).
+
+Read `PLAN.md`, then `PLAN_PHASE_TWO.md` → `THREE` → `FOUR` → `FIVE` for the history and the tier
+contract. Struck-through rows are fixed; do not re-report them. **Section 1.2 below supersedes any
+phase-five row that contradicts it.**
+
+### 1.2 What phase five settled — do not re-report these
+
+Nine defects, all fixed, each with a row that fails if it comes back:
+
+| # | Defect | Fix | Pinned by |
+|---|---|---|---|
+| 1 | `pruneStaleResults()` unset an entry; the next read layered the default branch's entry for the same test id back in, so a renamed/removed test stayed "previously unsuccessful" on a feature branch forever | `Graph::baselineFor()` layers per *file* once a branch has had a complete run (new `complete` flag on the baseline); a key minted by a narrowed run keeps the per-test-id merge | `StateReclamation` → *a pruned result does not come back from the fallback*, *the fallback still reaches a branch that has never run a test file* |
+| 2 | A cached failure whose test file was deleted was never reclaimed, so `--filtered` degraded to a full replay on every later run | `hasUnlocatedTestsToRerun()` widens only for a path it cannot *address*; `Graph::pruneResultsForMissingFiles()` + `pruneMissingTests()` run on every complete write | `StateReclamation` → *a cached failure whose test file was deleted stops widening later runs*, *a complete run reclaims the entry and the edge of a deleted test file* |
+| 3 | A detached HEAD is read-only for writes, but three paths still *deleted*: structural drift, `--fresh` (`Storage::purge`), and the corrupt-graph discard. The checkout that wiped the baseline could never rebuild it | `Tia::deleteState()` no-ops when detached; `Storage::purge` guarded | `StateReclamation` → the three *a detached HEAD does not purge…* rows |
+| 4 | A status int outside 0–8 became `TestStatus::unknown()`, which `ReplayType` folded into `Failure` — a green test went red, exit 1 | `Graph::getResult()` returns `null` for an unknown status (re-run, don't replay); `shouldRerunStatus()` treats unknown as re-run | `HostileState` → *a cached status this build cannot interpret is re-run, not replayed* |
+| 5 | Notice/deprecation/warning (3/4/6) decode fine but `ReplayType` had no case, so they also folded into `Failure` | Explicit `Pass` cases — those statuses only reach replay when the configured `failOn*` / `displayDetailsOn*` policies say they do not matter | `HostileState` → *a cached status with no replay of its own does not fail the run* |
+| 6 | `Graph::decode()` took `baselines`, `edges` and `files` verbatim; one malformed entry raised a `TypeError` inside a test | `decodeBaselines()` / `decodeResults()` / `decodeEdges()` / `decodeFiles()` validate every field. Numeric-looking keys are cast, not filtered — a branch named `12345` decodes as an `int` | `HostileState` → *a graph whose shape is wrong everywhere is repaired rather than trusted* |
+| 7 | Baseline keys grew forever — one full copy of the suite per branch ever created | `ChangedFiles::branchNames()` (local + remote refs) + `Graph::pruneMissingBranches()`, on complete writes only, and only when the fallback branch is visible in the refs | `BranchShapes` → *deleting many branches reclaims every one of their baselines* and the four rows around it |
+| 8 | A test that triggered a deprecation was recorded as `status=0`, because PHPUnit emits `Passed` for it and TIA had no issue subscribers. A fresh `--fail-on-deprecation` run exited 1; the replayed one exited 0 | Six subscribers (`Notice`/`PhpNotice`/`Deprecation`/`PhpDeprecation`/`Warning`/`PhpWarning`) feed `ResultCollector`; most-important-status-wins; a plain `Passed` does not downgrade a triggered issue; `@`-suppressed issues are ignored | `IssueStatuses` → *a triggered issue is recorded as itself, not as a pass*, *a cached deprecation still fails the run that asked to fail on one* |
+| 9 | A replay wrote back the status it *looked* like from outside, so a cached deprecation replaying as a pass was persisted as `0` — defect 8's fix eroded after one run | `Tia::replayedAsRecorded()` writes back the cached status and message for replayed tests, in the sequential path and in the worker flush | `IssueStatuses` → *replaying a cached issue does not downgrade it to a pass* |
+| 10 | A run torn down mid-file (an `exit()` inside a test) still flushed what it had, and the parent read that as licence to prune the siblings it never reached. Sequential and parallel disagreed | `ResultCollector::hasUnfinishedTest()` demotes such a run to results-only, in `terminate()` (the shutdown path) and in `addOutput()` | `StateReclamation` → *a run torn down mid-file does not prune the tests it never reached* |
+
+**One existing assertion was changed.** `DefaultBranchWriteTier > filtered mode falls back to a full
+replay when a cached failure cannot be located` used `tests/Unit/DeletedTest.php` — a path that
+resolves but does not exist, which is precisely the shape behind defect 2. It now points at
+`/build/agent/…`, so it still pins the widening safety net for the case where widening can help. If
+you disagree with that reading, that is a finding, not a licence to change it back quietly.
+
+### 1.3 Attacked in phase five and found solid — do not spend time here again
+
+- **Parity.** Sequential vs `--processes=1/2/8` across replay-with-edit, `--filtered` with a cached
+  failure, a first run on a feature branch, `--bail`, `--stop-on-failure`, `--compact`: identical
+  tally *and* identical graph delta every time.
+- **Hostile state dir.** Empty / truncated / not-JSON / JSON scalar / JSON list / `null` / `{}` / NUL
+  bytes; `graph.json` as a directory; a read-only state dir; dangling and negative edge ids; a result
+  `file` pointing outside the project; `schema: 2`. All degrade to "run the tests", exit 0.
+- **Status int mapping.** `ResultCollector` (`asInt()`), `Graph::getResult()` and `TestStatus::from()`
+  agree exactly on 0–8. No off-by-one.
+- **`FileState::write`** is tmp + rename, so concurrent runs cannot tear a file. Racing runs are
+  last-writer-wins **by design** — treat as a decision, not a bug, unless you can show data loss
+  worse than that.
+- **Branch names.** Slashes, dots, unicode, digits-only, 180 characters, case-only differences,
+  remote-only branches, worktree branches: all keyed and reclaimed correctly.
+- **`sha`/`tree` layering.** No shape found that under-reports changed files. The fallback `tree` only
+  drops a file whose current content hashes identically to what the fallback ran with, which is sound.
+
+### 1.4 Known and deliberately unfixed
+
+| Item | Why it is still open |
+|---|---|
+| Reclamation is skipped when a complete run executes **zero** tests | Stale edges linger until a run that executes at least one test. Writing the graph from a run that produced nothing costs more than it buys. Revisit if you find a real project stuck there. |
+| SIGINT never reaches the suite (`PcovRestarter` re-exec) | Real, but signal handling outside the TIA read/write path. Needs its own pass. |
+| Orphaned state dirs when the origin URL changes | `Storage::projectKey()` keys on the origin identity so clones share a graph. Changing the remote silently moves TIA to a fresh dir and nothing reclaims the old one. Unbounded growth in `~/.pest/tia`. |
+| `environmental` fingerprint holds only `php_minor` | Nuno declined. The `clearResults()` drift path is therefore latent — it becomes live the moment that bucket grows. **Do not re-flag the `PHP_MAJOR_VERSION` line itself.** |
+| PLAN.md §3 (raw coverage flags leave filtered mode on) | **No longer reproduces** — `coverageReportActive()` consults `COVERAGE_REPORT_FLAGS` now. Struck. |
+
+---
+
+## Part 2 — The invariants to attack
+
+Same list as phase five; 1, 2, 4, 5, 7 and 8 are now well covered, so weight your effort toward 3 and
+6 and toward the *recording* half of the system, which nothing below the plugin has ever probed.
+
+1. **Parity.** `pest <args>` and `pest --parallel --processes=N <args>` must leave the same graph and
+   reach the same tally. Hard rule. `Project::SEQUENTIAL_AND_PARALLEL` encodes it; use it on every new
+   write-path row.
+2. **The tiers hold.** COMPLETE / RESULTS-ONLY / HARD-SUPPRESSED, exactly one each, no leaking.
+3. **Replay is faithful.** ← *weak spot.* A replayed test reports the same status, message, time and
+   assertion count as the recorded run. Phase five fixed statuses; **edges** are unproven.
+4. **Reads never write.**
+5. **A branch never corrupts another branch's baseline.**
+6. **Nothing is unbounded.** ← *weak spot.* Baseline keys are reclaimed now; `files`, `edges`, worker
+   partials, coverage caches and orphaned state dirs are not.
+7. **A hostile state dir cannot break a run.**
+8. **Git shapes are all handled.**
+
+---
+
+## Part 3 — Leads to reproduce first (Pass A)
+
+Ranked by expected value. Everything here is **unexplored**, not merely unfixed — phase five never
+opened these files.
+
+### M1 — the recording path with a real coverage driver · **highest value**
+
+Everything phase five did was driver-independent by design (seed a graph, never record one). Nothing
+verified that a *recorded* graph is correct. This is the biggest blind spot in the audit.
+
+- Do the recorded edges match what the test actually touched? Record with pcov, then hand-check
+  `edges` against the source files each fixture test uses.
+- `PLAN.md` §4: **`pest --tia --coverage` narrows edges** — `Feature/ExampleTest` recorded with 2
+  files instead of 16, dropping self-edges. Same observable shape as the parallel bug G12 that phase
+  four closed, likely a different mechanism (the piggyback collector is scoped by `phpunit.xml
+  <include>`, the pcov-restarted recorder is not). **Confirm whether these are one fix or two.**
+- `Recorder::activateLinkTracking()` (piggyback) vs `activate()` (pcov restart) must produce the same
+  edge set for the same suite. Compare them directly.
+- `keepExisting: $this->piggybackCoverage` in `replaceEdges()` — what happens to a test whose edges
+  genuinely shrank while piggybacking?
+
+Rows for this **must** be `->skipOnPhpVersionsWithoutCoverage()`-style guarded, or seeded, or CI goes
+red on `php84`. That constraint is why phase five skipped it; solve it deliberately rather than by
+accident. Adding a coverage-driver guard helper to the fixture is a legitimate deliverable.
+
+### M2 — `BaselineSync` (621 lines, never opened)
+
+The remote-baseline fetch is the only path where a graph arrives from **another machine**, which is
+exactly where the hostile-state work matters most and where none of it has been exercised.
+
+- A fetched baseline whose `fingerprint` matches but whose `files`/`edges` describe a different tree.
+- A fetched baseline recorded on a branch this checkout does not have.
+- `fetchIfAvailable()` under a broken network, a 404, a truncated download, a non-gzip body.
+- `KEY_FETCH_COOLDOWN` — does it bound retries, and does a corrupt cooldown file break a run?
+- Interaction with defect 7's branch GC: a fetched baseline carries branch keys this clone has never
+  heard of. **They will be pruned on the next complete write.** Is that right, or must fetched keys be
+  exempt? This is a real question, answer it.
+
+### M3 — selection paths nobody has probed
+
+`Graph::affected()` is ~600 lines and phase five only exercised the plain PHP-edge path.
+
+- **Migrations** → `TableExtractor` → `testTables` intersection. What happens with an unparseable
+  migration, a migration that drops a table, a squashed schema dump?
+- **Blade** — `bladeAncestorsFor()` walks `@include`/`@extends`/`<x-*>` transitively. Cycles?
+  Depth? A component referenced only dynamically?
+- **Inertia** — `componentForInertiaPage()`, `jsFileToComponents`, `JsModuleGraph::buildStrict()`.
+  What if `vite` is missing, or the resolver returns garbage?
+- **`usesSiblingHeuristicForUnknownPhp()`** — a hard-coded list of Laravel directories. A changed file
+  in `app/Providers/` widens to every test whose deps share that directory. Measure how much that
+  over-selects on a real tree.
+- **Arch tests** — `testSourceDeclaresArchGroup()` greps the source with three regexes. False
+  positives (the string `arch(` in a comment) select the file on *every* PHP source change.
+
+### M4 — git shapes phase five left alone
+
+- A repo with **no commits yet** (`currentSha()` returns null / git fails).
+- **Submodules** — a changed file inside one; `git status --porcelain` reports the submodule path.
+- A repo whose root is **above** the pest project — `TiaRequiresRepositoryRoot` panics deliberately;
+  confirm it still panics and writes nothing.
+- **Shallow / single-branch CI checkouts.** Defect 7's guard (`fallbackBranch` must be visible in the
+  refs) was reasoned about, not measured. Build one and check nothing is over-pruned.
+- A branch **behind** the recorded sha, so `merge-base --is-ancestor` fails and the graph is declared
+  unreachable. Does it recover, or thrash?
+
+### M5 — a real concurrent race
+
+Phase five established `FileState::write` is atomic and called it last-writer-wins by design. Nobody
+launched two runs. Launch them: a watcher plus a manual run, two `--tia` processes on one project,
+`--parallel` where the parent writes while a straggler worker flushes. Look for **loss worse than
+last-writer-wins** — a partially-merged baseline, a pruned entry from a run that never saw the file,
+worker partials from run A consumed by run B (`KEY_WORKER_*` are not namespaced per run).
+
+That last one is the sharpest: `purgeWorkerPartials()` deletes *all* partials by prefix, so two
+concurrent parallel runs will eat each other's. Probe it.
+
+### M6 — the unbounded remainder
+
+Defect 7 reclaimed baseline keys. These still grow:
+
+- `files` and `edges` — a deleted *source* file's entry is never removed (`pruneMissingTests()` only
+  covers test files). Every rename leaves an orphan id forever.
+- Orphaned state dirs under `~/.pest/tia` (see 1.4).
+- `KEY_COVERAGE_CACHE` / `KEY_COVERAGE_MARKER` — who deletes them, and when?
+- Worker partials when a worker dies before `terminate()`.
+
+Measure the growth on a realistic tree before proposing anything. Then **ask** — a cap or a GC is a
+behaviour choice.
+
+---
+
+## Part 4 — The harness
+
+### 4.1 The scenario suite
+
+`tests/Features/Tia/*` scaffold a throwaway git project into a temp dir, run a **real `pest`
+subprocess** against it, and diff the graph it wrote. Everything lives in `tests/Fixtures/Tia/`:
+
+| Class | What it gives you |
+|---|---|
+| `Project` | `make(branch, overlay:)`, `withoutGit()`, `seed(branch, sentinel:, failing:)`, `seedFor($root, …)`, `pest(...$args)`, `pestWithEnvironment($dir, $env, ...$args)`, `pestIn($dir, ...)`, `write($rel, $contents)`, `path($rel)`, `graph()`, `branchKeys()`, `graphDir()`, `graphExists()`, `snapshot()`, `delta()`, `mutateGraph(fn)`, `addBaseline($branch)`, `worktree($branch)`, `destroy()`, `destroyAll()`, `SEQUENTIAL_AND_PARALLEL` |
+| `GitRepo` (`$project->git()`) | `switchTo($b, new:)`, `rename($from, $to)`, `detach()`, `commit($msg)`, `config($k, $v)`, `addOrigin()`, `removeOrigin()`, `setOriginHead($b)`, `unsetOriginHead()`, `worktree()`, `sha()`, `branchNames()`, `run([...])` for anything else |
+| `GraphDelta` (`$project->delta()`) | `writtenCount()`, `added()`, `removed()`, `branchKeys()`, `baselineUntouched($b)`, `shaMoved()`, `treeMoved()`, `edgesMoved()`, `filesMoved()`, `fingerprintMoved()`, `structureMoved()`, `isResultsOnly()`, `isHardSuppressed()`, `summary()` |
+| `PestResult` (returned by `pest()`) | `replayed()`, `uncached()`, `affected()`, `tally()`, `output`, `exitCode`, `describe()` |
+
+The fixture app is 3 test files / **6 tests** (`Project::TOTAL_TESTS`); `Project::EDGES` and
+`Project::TESTS` describe the graph `seed()` writes. `Project::testId($file, $description)` builds a
+result key. Overlays in `tests/Fixtures/Tia/overlays/<name>/` supply a different `tests/Pest.php` —
+that is how you configure `pest()->tia()->…` for a scenario.
+
+**If the fixture cannot express your case, extend the fixture.** A new `GitRepo` verb, a new overlay,
+or a coverage-driver guard is a legitimate part of the deliverable. Do not water down a scenario to
+fit the current helpers. Phase five added `GitRepo::commit()` usage, numeric-key handling in
+`Project::branchKeys()` and `GraphDelta`, and used `$project->write()` to author test files inline —
+follow that pattern.
+
+### 4.2 The sentinel discriminator — read before writing any assertion
+
+`seed()` writes a graph **and then rewrites every cached result to `time=9.999`, `assertions=42`**
+(only where assertions are non-zero — risky/skipped/incomplete statuses are *derived* from "performed
+no assertions", so falsifying those would rewrite the status on replay), then snapshots. Therefore:
+
+- `$delta->writtenCount()` is the only reliable way to tell **"replayed"** from **"executed and wrote
+  back the same values"**. `0` means nothing was written.
+- `isResultsOnly()` = no structure moved, no `sha`/`tree` movement, nothing added or removed.
+- `isHardSuppressed()` = the graph is byte-identical.
+- A replayed suite reports inflated assertion counts (6 tests × 42). That is the sentinel, not a bug.
+
+The three write tiers, unchanged since phase two:
+
+- **COMPLETE** — may change everything.
+- **RESULTS-ONLY** — may change only `baselines[<branch>].results` for tests that ran; never removes
+  an entry, never adds a result for a test file absent from `edges`, never touches
+  `sha`/`tree`/`edges`/`files`/`fingerprint`.
+- **HARD-SUPPRESSED** — may change nothing.
+
+One addition from phase five: a complete run on a **non-default** branch also sets
+`baselines[<branch>].complete = true`. It is deliberately *not* set on the default branch, so a clean
+green run there stays byte-identical.
+
+### 4.3 Running them
+
+They are in the `integration` group (`tests/Pest.php`), so `composer test:unit` skips them. **A
+directory argument finds nothing** — pass files, space-separated, as separate argv entries:
+
+```bash
+PAO_DISABLE=1 php84 bin/pest tests/Features/Tia/BranchShapes.php tests/Features/Tia/CompleteRunWriteTier.php \
+  tests/Features/Tia/DefaultBranchReplay.php tests/Features/Tia/DefaultBranchResolution.php \
+  tests/Features/Tia/DefaultBranchWriteTier.php tests/Features/Tia/FilteredMode.php \
+  tests/Features/Tia/HostileState.php tests/Features/Tia/IssueStatuses.php \
+  tests/Features/Tia/PartialRunWriteTier.php tests/Features/Tia/StateReclamation.php
+
+PAO_DISABLE=1 php   bin/pest <same list>
+```
+
+**Both interpreters must be green.** `php84` is 8.4.x with **no pcov** — that is what CI has
+(`.github/workflows/tests.yml` sets `coverage: none`). `php` is 8.5.x with pcov — that is the dev
+machine. Any assertion that depends on a coverage driver passes locally and fails in CI. Concretely:
+
+- A **cold recording run writes no graph at all** without pcov/xdebug (it prints `Running in TIA mode,
+  however TIA is skipped as it needs ext-pcov or Xdebug`). **Seed a graph, never record one**, unless
+  the driver *is* the point of the row — see M1, which has to solve this properly.
+- A **PHP source file edit** driverless triggers `Detected PHP source changes but no coverage driver
+  is available` → full suite, `affected=0`. Edit *test* files, not `app/` files.
+- The `terminate()` path differs by driver: with pcov the plugin reaches the complete write through
+  the shutdown handler, without it the run exits earlier. Defect 10 only reproduced on `php`. **Run
+  every probe on both before believing it.**
+
+`PAO_DISABLE=1` is mandatory on every pest invocation and every probe: `laravel/pao` emits JSON under
+agents and corrupts the captured output.
+
+**Baseline: 161 scenario rows green on both interpreters**, at `b49ba062`. Per file:
+
+| File | Rows |
+|---|---|
+| `StateReclamation.php` | 37 |
+| `HostileState.php` | 25 |
+| `CompleteRunWriteTier.php` | 17 |
+| `DefaultBranchResolution.php` | 14 |
+| `BranchShapes.php` | 14 |
+| `DefaultBranchReplay.php` | 13 |
+| `IssueStatuses.php` | 13 |
+| `PartialRunWriteTier.php` | 12 |
+| `DefaultBranchWriteTier.php` | 10 |
+| `FilteredMode.php` | 6 |
+
+Plus 80 unit/arch rows (`tests/Unit/Plugins/Tia/*`, `tests/Arch.php`). If those numbers do not
+reproduce, stop and say so.
+
+### 4.4 Measure before you assert
+
+Never guess an expectation from reading the code. Probe first, in your scratchpad:
+
+```php
+<?php
+require '/Users/nunomaduro/Work/projects/pestphp/pest/vendor/autoload.php';
+use Tests\Fixtures\Tia\Project;
+
+$p = Project::make('master');
+$p->seed('master');
+$p->git()->switchTo('feature-x', new: true);
+$r = $p->pest('--tia');
+printf("tally=[%s] keys=[%s] %s\n", $r->tally(), implode(',', $p->branchKeys()), $p->delta()->summary());
+$p->destroy();
+```
+
+`PAO_DISABLE=1 php probe.php`. One project per scenario; always `destroy()`; `Project::destroyAll()`
+at the end. Run every probe on **both** interpreters before believing it.
+
+---
+
+## Part 5 — Ground rules
+
+- **Do not** run `composer test`. It takes minutes and you do not need it.
+- **`tests/.snapshots/success.txt` and the tally in `tests/Visual/Parallel.php` are stale right now** —
+  phase five added 89 rows and did not regenerate them. **Report that they need regenerating and let
+  Nuno run `composer update:snapshots`.** Do not run it yourself.
+- **Do not commit.** Leave the tree dirty.
+- **Do not touch the playground's `vendor/`.** If a finding truly needs the playground (25 real tests,
+  real timings), say so and ask — syncing it is a manual step Nuno owns.
+- Run `vendor/bin/phpstan analyse <the files you touched> --memory-limit=-1 --no-progress` and
+  `vendor/bin/pint <the files you touched>` before reporting. **Scope both to files you changed** —
+  Nuno edits `src/` live, and a repo-wide fixer will revert his work.
+- The fixture projects **hardlink `src/`**. If you edit `src/` while a scenario run is in flight,
+  those rows go red for no reason. Finish the edit, then run.
+- Keep scratch probes out of the repo.
+- **Never weaken an existing assertion to make something pass.** If an existing row contradicts your
+  fix, that is a finding: report the contradiction and ask. Phase five hit this once (see 1.2) and
+  rewrote the row to pin the *narrower* contract rather than deleting it — that is the bar.
+
+---
+
+## Part 6 — Reporting
+
+**Between passes**, not just at the end. Per finding:
+
+- **Reproduced (yes / no / hypothesis only)**, with the exact command and the measured
+  `tally` + `delta()->summary()` on **both** interpreters.
+- **Severity**, and say why in one line. The scale that matters here: *a test wrongly replayed as
+  passing* (worst) > *cache silently useless, full suite forever* > *graph grows / stale data* >
+  *cosmetic*.
+- **Fixed / deferred / needs-a-decision**, and the row that pins it.
+- For anything needing a decision: **one yes/no question**, no essay.
+
+Close with:
+
+1. The count of `tests/Features/Tia/*` green on **both** `php84` (no pcov) and `php` (pcov), against
+   the 161 baseline.
+2. Every row you added, and what invariant from Part 2 it defends.
+3. Which findings are still open, as yes/no questions.
+4. That the snapshots need regenerating — **do not regenerate them.**
+5. **What you looked at and found solid.** A list of attacks that did not break anything is a real
+   result: it tells the next phase where not to spend its time.
+
+---
+
+## Part 7 — Open questions carried into this phase
+
+Answer these before or during Pass C; they change what the fixes should be.
+
+1. A fetched remote baseline carries branch keys this clone has never heard of, and the branch GC will
+   prune them on the next complete write. **Should fetched keys be exempt?**
+2. Two concurrent parallel runs share the `worker-edges-*` / `worker-results-*` prefixes and
+   `purgeWorkerPartials()` deletes by prefix. **Should partials be namespaced per run, or is "do not
+   run two TIA suites at once" the contract?**
+3. `files` and `edges` never lose a deleted *source* file. **Cap, GC, or accept?**
+4. Orphaned state dirs accumulate under `~/.pest/tia` whenever a project's origin URL changes.
+   **Reclaim them, or accept?**

+# TIA default-branch fallback — phase three
+
+## Your task
+
+Fix [pestphp/pest#1823](https://github.com/pestphp/pest/issues/1823) — TIA's cached results never
+hit for repos whose default branch is not literally `main` — then re-run the **whole** conformance
+matrix against the playground app, plus the new section **L** that covers the fix.
+
+Work in this order, and **stop where the plan says stop**:
+
+1. **Part 1** — read the diagnosis. It is already measured; do not re-derive it, but do re-confirm
+   the two reproductions in Part 1.3 take ~2 minutes and prove your environment is sane.
+2. **Part 2** — implement the fix in the `pestphp/pest` repo. **Do not commit. Do not touch the
+   playground's `vendor/`.**
+3. **HARD STOP → Part 3.** Report the diff to Nuno and wait. He validates, commits, and syncs it
+   into the playground himself. You must not proceed until he confirms.
+4. **Part 4** — verify the sync landed, then run section **L** (new) and the full phase-two matrix
+   (**A–K**, all 156 rows) against the playground.
+5. **Part 5** — report in the given format.
+
+Per `CLAUDE.md`: **do not write new `pestphp/pest` unit tests and do not run `composer test`.** Make
+the change, report it, and ask whether repo tests should be added. The section-L rows are *playground
+invocations*, not repo tests — those are the deliverable and are always in scope.
+
+---
+
+## Part 1 — The diagnosis (already measured; commit `bfd5b756`)
+
+### 1.1 Root cause — two independent hardcoded `'main'` literals
+
+**(a) The read fallback.** `src/Plugins/Tia/Graph.php` — seven methods default the fallback to the
+literal `'main'`:
+
+| line | method |
+|---|---|
+| 579 | `recordedAtSha(string $branch, string $fallbackBranch = 'main')` |
+| 614 | `getAssertions(…, string $fallbackBranch = 'main')` |
+| 625 | `getTime(…, string $fallbackBranch = 'main')` |
+| 636 | `getResult(…, string $fallbackBranch = 'main')` |
+| 663 | `testFilesToRerun(string $branch, string $fallbackBranch = 'main')` |
+| 700 | `hasUnlocatedTestsToRerun(string $branch, string $fallbackBranch = 'main')` |
+| 811 | `lastRunTree(string $branch, string $fallbackBranch = 'main')` |
+
+They all funnel into `Graph::baselineFor()` (line 819), which *does* implement a real cross-branch
+fallback:
+
+```php
+if (isset($this->baselines[$branch]))                                         return $this->baselines[$branch];
+if ($branch !== $fallbackBranch && isset($this->baselines[$fallbackBranch]))  return $this->baselines[$fallbackBranch];
+return ['sha' => null, 'tree' => [], 'results' => []];
+```
+
+The mechanism is deliberate. The problem is that **no caller ever passes `$fallbackBranch`** — all
+nine call sites in `src/Plugins/Tia.php` (lines 419, 429, 432, 785, 857, 1026, 1031, 1048, 1056) pass
+only `$this->branch`. So on a `master`-named repo the second branch of `baselineFor()` can never
+fire, and the whole mechanism is dead code.
+
+`grep -rniE 'defaultBranch|symbolic-ref|init\.defaultBranch|origin/HEAD' src/` returns **nothing** —
+no default-branch resolution exists anywhere.
+
+**(b) The detached-HEAD default.** `src/Plugins/Tia.php:206` declares `private string $branch = 'main';`
+and `ChangedFiles::currentBranch()` (`ChangedFiles.php:208`) returns `null` for detached HEAD. So on
+detached HEAD `$this->branch` stays the literal `'main'` and is used for **both reads and writes** —
+minting a baseline key for a branch that does not exist. This is a *write*-side bug and a separate fix
+from (a).
+
+### 1.2 Not a regression
+
+`git log -S"fallbackBranch = 'main'"` bottoms out at `c7e32f5d feat(tia): continues to work on poc`.
+This is original PoC code, untouched by phase one. Phase one's change 1 modified
+`hasUnlocatedTestsToRerun()`'s file-existence check — one of the seven methods — without going near
+the fallback. Do not report it as a phase-one regression.
+
+No test anywhere exercises the mechanism: `tests/Unit/Plugins/Tia/Graph.php` uses `'main'` as the
+*actual* branch name, so those assertions pass whether or not the fallback exists. A branch-name
+mismatch is never tested.
+
+### 1.3 The two reproductions (re-confirm these before you start)
+
+Both on the playground, `master`-named default branch, zero local changes:
+
+```
+default = master                          default = main
+1. record on default   → full run (cold)  → full run (cold)
+2. 1st run on feature-x → 25 UNCACHED     → 25 replayed   ← (a)
+3. 2nd run on feature-x → 25 replayed     → 25 replayed
+4. back on default      → 25 replayed     → 25 replayed
+5. 1st run on feature-y → 25 UNCACHED     → 25 replayed
+```
+
+```
+master-only graph, then `git checkout --detach`, then `pest --tia`:
+  → 25 uncached, and keys become [master,main]   ← (b) spurious key
+```
+
+The cost is **one full run per new branch, forever**, with no output explaining why — the only clue
+is the `N uncached` count; the headline is just `─ Experimental TIA mode enabled.`
+
+### 1.4 Correction to phase two
+
+Phase two reported **H6 and H7 as passing. Both were false passes.** They ran after H5, which had
+renamed `master`→`main` and left a `main` key in the graph, so the hardcoded fallback resolved by
+accident. Re-measured against a clean `master`-only graph, both fail. Section L replaces them as the
+load-bearing rows; H6/H7 must be re-run **from a cold graph** this time (see Part 4.2).
+
+---
+
+## Part 2 — The fix to implement
+
+### 2.1 Recommended design
+
+**Step 1 — add a non-throwing resolver** to `src/Plugins/Tia/ChangedFiles.php`, next to
+`currentBranch()`:
+
+```php
+public function defaultBranch(): ?string
+```
+
+Resolution order, each step failing soft to the next:
+
+1. `git symbolic-ref --short refs/remotes/origin/HEAD` → strip a leading `origin/`
+2. `git config --get init.defaultBranch`
+3. `null`
+
+Unlike `currentBranch()`, this must **never throw** `MissingDependency` — it is advisory. Return
+`null` on any non-zero exit or empty output.
+
+**Step 2 — add a config surface.** `src/Plugins/Tia/Configuration.php` already exposes `always()`,
+`locally()`, `filtered()`, `baselined()`, `watch()`. Add:
+
+```php
+public function defaultBranch(string $branch): self
+```
+
+so `pest()->tia()->defaultBranch('master')` works in `tests/Pest.php`. Explicit config **always
+wins** over autodetection — that is the escape hatch when `origin/HEAD` is unset.
+
+**Step 3 — resolve once, in `Tia.php`.** The read path is hot (`getResult()` is called per test at
+line 419), so resolution must not shell out per call. Resolve alongside `$this->branch` at
+`Tia.php:1910`, under the existing `$branchResolved` guard:
+
+```php
+$this->fallbackBranch = $configuredDefaultBranch
+    ?? $changedFiles->defaultBranch()
+    ?? 'main';
+```
+
+**Step 4 — thread it into `Graph`.** Prefer a `Graph`-level property over editing nine call sites:
+add `Graph::setFallbackBranch(string $branch)`, change the seven signatures to
+`?string $fallbackBranch = null`, and resolve inside each with
+`$fallbackBranch ??= $this->fallbackBranch;`. `baselineFor()` itself needs no change. This keeps the
+public signatures backward-compatible and minimises blast radius.
+
+**Step 5 — fix the detached-HEAD write.** `Tia.php:206`'s `= 'main'` default must become the
+resolved default branch, so detached HEAD stops minting a phantom key.
+
+### 2.2 Invariants the fix must not break
+
+These are all covered by existing matrix rows — the fix is wrong if any of them moves:
+
+- **Read-only.** The fallback must affect *reads* only. Writes go through `ensureBaseline($branch)`
+  and must keep using the real current branch. Otherwise H1–H4/H8 ("no baseline key other than the
+  real branch") break.
+- **H9** — a non-git dir with `--tia` must still raise
+  `MissingDependency: The feature "Tia mode" requires "git".` Adding a soft resolver must not
+  swallow that.
+- **H10** — plain `pest` in a non-git dir must still run and create no baseline dir.
+- **A2/A3** — cold-graph recording unchanged.
+- **I1/E3** — clean+green `--tia --filtered` must still be a true zero-delta run.
+- Filtered mode reads `testFilesToRerun()` and `hasUnlocatedTestsToRerun()`, so the fallback must
+  reach those two as well, not just `getResult()`.
+
+### 2.3 Decisions for Nuno (raise these at the Part 3 stop)
+
+- **D1** — Consult `origin/HEAD` at all? It requires `git remote set-head` and is absent in many CI
+  checkouts and all remote-less repos. Config + `init.defaultBranch` only is simpler but helps fewer
+  people out of the box. *Recommendation: keep it, first in the chain, since it fails soft.*
+- **D2** — Single-key heuristic: if the graph holds exactly one baseline key, use it as the fallback?
+  Fixes the issue with zero git calls, but is implicit and surprising when several keys exist.
+  *Recommendation: no.*
+- **D3** — Should detached HEAD write a baseline at all, or be read-only? Current behaviour mints a
+  key. *Recommendation: read-only.*
+- **D4** — Should `pest()->tia()->defaultBranch()` validate that the branch exists, or accept any
+  string? *Recommendation: accept any string; a nonexistent name degrades to a full run, which is
+  safe.*
+
+---
+
+## Part 3 — HARD STOP
+
+When the code is written:
+
+1. Show Nuno the diff (`git -C /Users/nunomaduro/Work/projects/pestphp/pest diff`) and a one-paragraph
+   summary of each file's change.
+2. Answer/raise the D1–D4 decisions.
+3. State explicitly that you have **not** committed and have **not** synced `vendor/`.
+4. Ask whether repo unit tests should be added (per `CLAUDE.md`), describing the tests you have in
+   mind — do not write them yet.
+5. **Wait.** Nuno commits and applies the change to the playground.
+
+**Never sync the playground's `vendor/` yourself.** `vendor/pestphp/pest` there is a dist copy, not a
+symlink (composer installed `dev-fix/tia-filtered as 5.2.0`), so pest-repo edits do not reach it. Say
+what is stale and wait. This applies to before/after contrasts too.
+
+Once he confirms, verify the sync actually landed before measuring anything:
+
+```bash
+V=/Users/nunomaduro/Work/projects/playground/laravel/vendor/pestphp/pest
+grep -c 'defaultBranch' "$V/src/Plugins/Tia/ChangedFiles.php"   # must be ≥ 1
+for f in src/Plugins/Tia.php src/Plugins/Tia/Graph.php src/Plugins/Tia/ChangedFiles.php \
+         src/Plugins/Tia/Configuration.php; do
+  diff -q "/Users/nunomaduro/Work/projects/pestphp/pest/$f" "$V/$f" >/dev/null \
+    && echo "SAME $f" || echo "STALE $f"
+done
+```
+
+If anything reports `STALE`, stop and tell him. State in your final report which pest commit produced
+the playground numbers.
+
+---
+
+## Part 4 — Measurement
+
+### 4.1 Environment and traps
+
+**Playground:** `/Users/nunomaduro/Work/projects/playground/laravel` (branch `master`).
+
+1. **Every** pest invocation needs `PAO_DISABLE=1` — the app has `laravel/pao`, which emits JSON when
+   it detects an agent.
+2. **Pin the interpreter to `php85`.** The playground requires PHP `>= 8.4.1` *and* pcov. Locally only
+   `php85` (8.5.8) has both — `php84` (8.4.23) has no pcov, and the bare Herd `php` shim has been
+   observed drifting to 8.3.32 mid-session, which kills every run in
+   `vendor/composer/platform_check.php`. Also put a `php` → `php85` symlink first on `PATH`: the
+   `--shard` list-tests probe spawns a subprocess via bare `php`, not `PHP_BINARY`.
+3. **Never run `git checkout .` or `git checkout -- composer.lock` in the playground.** It has four
+   pre-existing user-modified files — `AGENTS.md`, `CLAUDE.md`, `composer.json`, `composer.lock`. Scope
+   resets to `git checkout -- tests app` / `git clean -fd tests app`. For `phpunit.xml` and
+   `composer.lock`, copy aside and copy back, verifying with `shasum`.
+4. **zsh does not word-split unquoted parameters.** A `$PEST` string containing a space becomes one
+   command name. Route every invocation through `eval` (the `pest()` helper below does this).
+5. Comment-only edits to a test file are **not** changes (AST-level hashing). Use semantic edits.
+6. **The sentinel technique must not falsify `assertions` on zero-assertion tests.** A
+   risky/skipped/incomplete status is *derived* from "performed no assertions", so patching those to
+   `42` rewrites the status on replay and destroys the discriminator — it shows up as a phantom
+   `status 5→0` defect. The `sentinel.php` below only patches `assertions` where it is already
+   non-zero. With that, a full replay gives a clean `rewritten=0`.
+7. Restore branch state after every L row. Several rows rename or detach; leaving a stray `main` key
+   in the graph is exactly what produced phase two's false H6/H7 passes.
+
+### 4.2 Reference numbers
+
+The playground already carries the phase-two fixtures at commit `fb2e77e` — **do not rebuild them.**
+A healthy sequential `--tia` graph is:
+
+> **`files=27`, 10 edge keys (one per test file), self-edge on all 10, `n=25` results.**
+
+`sha` will differ once Nuno commits the vendor sync — re-derive it once and use it throughout. The
+`files`/`edges`/`n` numbers hold as long as no test fixture changes. Suite shape: 10 test files, 25
+tests, including six deliberate status fixtures (skipped, todo, incomplete, risky, warning,
+deprecation), a 3-row dataset, a `smoke` group, an env-driven flaky test (green unless
+`FLAKY_FAIL=1`), and the annotation set (`covers`/`note`/`flaky`/`issue`/`pr`/`ticket`/`assignee`).
+
+**Re-run H6 and H7 from a cold graph** (`rm -rf` the graph dir, record on `master` only, *then*
+branch/detach). Their phase-two results are void.

+
+`cmp.php` (verbose per-entry version of the same) and `summarise.php` / `edgediff.php` are in
+`PLAN_PHASE_TWO.md` §"Graph summariser" — reuse them for drill-downs. Reading the verdict:
+
+- `w=` — entries actually **written**. Under sentinel patching this is the only reliable way to tell
+  "wrote identical values" from "wrote nothing". A full replay must give `w=0`.
+- `struct:ok` + `+0 -0` — no prune, no edges/files/fingerprint movement. Required by RESULTS-ONLY.
+- `STRUCT:branchkeys(...)` — a new baseline key appeared. For section L this is the headline signal.
+
+### 4.4 Section L — new rows for this fix
+
+Tiers, unchanged from phase two: **COMPLETE** may change everything · **RESULTS-ONLY (RO)** may
+change only `baselines[<branch>].results` for tests that ran, and must never remove an entry, add a
+result for a test file absent from `edges`, or alter `sha`/`tree`/`edges`/`files`/`fingerprint` ·
+**HARD-SUPPRESSED** may change nothing.
+
+Every L row starts from a **cold graph recorded on the named default branch only** — verify
+`keys=[<default>]` before branching. Restore branch state afterwards.
+
+| # | Case | Target outcome |
+|---|---|---|
+| L1 | default `master`, record, `git switch -c feature-x`, `pest --tia`, zero changes | **all 25 replayed** (`w=0`), not `25 uncached`. The headline fix. |
+| L2 | as L1 but default `main` | still all replayed — regression guard, this already worked |
+| L3 | default `trunk`, then `develop` | replayed for both; the fix must not special-case two names |
+| L4 | L1, then a *second* new branch `feature-y` | replayed too — the toll must not return per branch |
+| L5 | L1 then edit `app/Services/Calculator.php` on `feature-x` | narrows to the 2 affected files (`CalculatorTest` + `AnnotationsTest`, which `covers` it); the other 17 replay |
+| L6 | L1 with `--tia --filtered` | filtered mode reads the fallback too (`testFilesToRerun`, `hasUnlocatedTestsToRerun`) → `No affected tests found`, zero delta |
+| L7 | L1 with `--tia --parallel` | fallback works in workers as well as the parent |
+| L8 | L1, then `pest --tia` twice on `feature-x` | idempotent; second run also `w=0` |
+| L9 | detached HEAD on a `master`-only graph | replays, and **no `main` key minted** — `keys` stays `[master]`. Bug (b). |
+| L10 | `pest()->tia()->defaultBranch('master')` in `tests/Pest.php`, repo default renamed away | config wins over autodetect |
+| L11 | config set to a nonexistent branch (`defaultBranch('nope')`) | degrades to a full run; no crash, no phantom key |
+| L12 | no remote at all (`git remote remove origin` if present) | still resolves (via `init.defaultBranch`) or degrades safely — must not throw |
+| L13 | branch name with a slash (`feature/x/y`) | replayed; no key-splitting bugs |
+| L14 | L1, then confirm writes | `feature-x` gets its **own** key; the `master` key is **not** written to (fallback is read-only) |
+| L15 | git worktree on a new branch (the issue's scenario) | replays from the default-branch baseline |
+| L16 | non-git dir, `pest --tia` | still `MissingDependency: The feature "Tia mode" requires "git".` — the soft resolver must not swallow it |
+| L17 | non-git dir, plain `pest` | runs normally; no baseline dir created |
+| L18 | count `git` subprocesses during one `--tia` run | default-branch resolution is cached, not one call per test. Probe by shimming `git` on `PATH` to a logging wrapper. |
+
+L10–L11 need a `tests/Pest.php` edit — that file is tracked and **outside** the `tests app` reset
+scope in practice (it lives in `tests/`, so `git checkout -- tests` does restore it; verify with
+`git status` after).
+
+For L16/L17, build a throwaway non-git project — and note the trap that burned phase two: a
+**symlinked** `vendor` makes Pest resolve the project root back to the playground (identical baseline
+hash), silently invalidating the test. Use a hardlinked copy:
+
+```bash
+NG="$SP/nogit"; rm -rf "$NG"; mkdir -p "$NG"
+cp -R composer.json composer.lock phpunit.xml artisan tests app bootstrap config routes resources storage "$NG/"
+[ -f .env ] && cp .env "$NG/"
+cp -Rl vendor "$NG/vendor" || cp -R vendor "$NG/vendor"
+```
+
+Confirm the baseline path differs (`nogit-<hash>`, not `laravel-4a455a95622ac0ec`), and delete both
+the temp project and its `~/.pest/tia/nogit-*` dir afterwards.
+
+### 4.5 Re-run the phase-two matrix (A–K, 156 rows)
+
+Re-run every row of `PLAN_PHASE_TWO.md` Part 2 against the fixed build. No row's status is trusted
+until re-measured — the fix touches `Graph`'s read path, which nearly every row exercises. Sections
+**A, B, H, I** are the load-bearing ones here (H is branch-key resolution; I is filtered mode; both
+consume the changed methods directly). **H6 and H7 must be re-derived from a cold graph** (Part 1.4).
+
+Most rows batch cheaply — phase two ran C1–C20 in one call at roughly one line of output each. Use
+`oneline.php` for the sweep and `cmp.php` only to drill into anomalies.
+
+### 4.6 Known pre-existing failures — do not report as regressions
+
+| item | status |
+|---|---|
+| ~~**G4 / G4b** — parallel replay clobbers cached `time` on all non-executed tests.~~ | **Struck in phase four — does not reproduce.** `flushWorkerReplay()` applies `resultTime()` worker-side before writing the partial, so the parent's verbatim read of `$result['time']` is reading values that were already corrected. Pinned by `a parallel replay keeps the recorded time of tests that did not run` (`tests/Features/Tia/CompleteRunWriteTier.php`), which sentinels every cached `time` and asserts a parallel replay writes nothing. |
+| **C19** — `--tia --uses=…` cannot be fixtured. TIA hard-errors on PHPUnit classes (`EnsureTiaIsRunningPestTestsOnly`), and Pest has no chainable `->uses()`. | **Expected behaviour per Nuno.** Verify the tier (`w=0`, RO, notice) and move on. Not a defect. |
+| **J11** — `--repeat` is not a Pest option (`Unknown option "--repeat"`). | **Don't care per Nuno.** Mark SKIP. |
+| **J10** — `--random-order-seed` alone exits 1 with a WARN. Identical without `--tia`. | Pre-existing Pest behaviour, unrelated. Tier still holds. |
+
+---
+
+## Part 5 — Reporting
+
+Per row: **tier respected (yes/no)**, the **graph delta** under sentinel patching, and for any failure
+the **pre-fix contrast** so a regression is told apart from a pre-existing defect. For a pre-fix
+contrast you need `db70017c` (or `bfd5b756` for "before phase three") files swapped into the
+playground's `vendor/` — that is a sync, so **ask Nuno first** and always restore afterwards.
+
+State which pest commit produced the numbers. Close with:
+
+1. Whether L1–L18 all pass (the fix works).
+2. Whether A–K regressed anywhere relative to phase two's 154/156.
+3. The D1–D4 decisions as implemented.
+4. Anything still open — including G4, which will still be failing.
+
+Leave the playground on `master` with only the four user-modified files dirty, no stray branches, and
+no leftover `~/.pest/tia/*` dirs beyond `laravel-4a455a95622ac0ec`.

+# TIA write-tier conformance — phase two
+
+## Your task
+
+**Re-run all 156 rows of the matrix in Part 2 from scratch, against the playground app** at
+`/Users/nunomaduro/Work/projects/playground/laravel`. Every row, including the ones already marked
+VERIFIED or PASS — the point of phase two is that no row's status is trusted until it has been
+re-measured against the current code. The `Phase 1` column is prior evidence and a hint at what to
+watch, never a reason to skip a row.
+
+These are **not** the `pestphp/pest` repo's own tests (`composer test`) — do not run those. Each row is
+a `pest` invocation against the playground's suite, followed by a diff of the TIA graph it wrote.
+
+Report, per row: tier respected (yes/no), the graph delta under sentinel patching, and — for any
+failure — the pre-fix contrast so a regression is told apart from a pre-existing defect. Do **not**
+stop at reading this file or summarising it; the deliverable is executed results.
+
+Work in this order: **Part 1 (environment traps) → Part 1b (build the fixtures — the playground has
+none of them) → Part 2 (the matrix) → Part 3 (priorities)**. The matrix is too large for one context;
+take it one lettered section at a time and report as you finish each. Sections A, B, G, I and K are
+the load-bearing ones — do those first if you run short.
+
+Phase one implemented `PLAN.md` Part 1 items 1–4 plus three §5 items. This file turns the matrix into
+a conformance check rather than a bug list.
+
+Code under test: `pestphp/pest` at `/Users/nunomaduro/Work/projects/pestphp/pest`, branch
+`fix/tia-filtered`, commit **`bfd5b756`** or later. Verify with
+`grep -c 'recordsEdgesInWorkers\|recordsEdges' src/Plugins/Tia.php` → at least 3 hits. Pre-fix
+baseline for every contrast is **`db70017c`**.
+
+---
+
+## Part 0 — What phase one changed
+
+| # | Change | Files |
+|---|---|---|
+| 1 | `hasUnlocatedTestsToRerun()` stats the file, so a deleted test file is "unlocated" | `src/Plugins/Tia/Graph.php` |
+| 2 | `enterReplayMode()` uses `activateLinkTracking()` under piggyback coverage | `src/Plugins/Tia.php` |
+| 3 | `enterReplayMode()` stamps `TIA_PIGGYBACK_COVERAGE` for workers | `src/Plugins/Tia.php` |
+| 4 | `replaceEdges(…, keepExisting:)` — piggyback edges seed empty sets, never overwrite populated ones | `Graph.php`, `Tia.php` |
+| 5 | `renderFreshGraph()` stops claiming "fresh graph" when the graph is kept; reason reworded to `recording a coverage baseline` | `Tia.php` |
+| 6 | `COVERAGE_REPORT_FLAGS` + `coverageReportActive()` union over `originalArguments`; new `pestCoverageActive()` keeps the coverage-cache marker/hijack on Pest's own `--coverage` | `Tia.php` |
+| 7 | `Tia::recordsEdgesInWorkers()` + `WrapperRunner::handleTia()` inject `-d pcov.directory=<root>` into worker argv | `Tia.php`, `src/Plugins/Parallel/Paratest/WrapperRunner.php` |
+| 8 | Sequential record runs announce structural drift via `renderFreshGraph()` | `Tia.php` |
+| 9 | `Graph::getTime()` + `cachedTimeByTestId` + `resultTime()` preserve replayed durations; edge-less write guard is now `$recordsEdges = $complete && ($markKnownTestFiles \|\| $this->recordingActive)` | `Graph.php`, `Tia.php` |
+
+Deliberately **not** done: `PLAN.md` §5 SIGINT propagation, §5 warning/deprecation `status=0`
+mapping, and all of §6 (playground annotation fixtures). The vacuous C rows below stay vacuous.
+
+### Target-outcome changes this forces
+
+Two rows in the original matrix asserted the **old**, buggy behaviour. Their targets are updated
+below — do not report them as regressions:
+
+- **B10** was "`time` differs; statuses stable". Change 9 means replayed entries now **keep** their
+  recorded `time`. New target: `time` differs only for tests that actually executed.
+- **B12** gains an edge-preservation assertion it never had (see K1).
+
+### One known-failing repo test
+
+`tests/Unit/Plugins/Tia/Graph.php:69-76` asserts `hasUnlocatedTestsToRerun('main')` is `false` for
+`tests/Feature/FooTest.php` under `new Graph(sys_get_temp_dir())` — a path that does not exist. That
+assertion encodes the I9 bug and **will fail** under change 1. It needs re-pointing at a root/file
+that exists (e.g. `dirname(__DIR__, 4)` + `'tests/Unit/Plugins/Tia/Graph.php'`). Left untouched by
+request; it is a repo-test matter, not a playground one.
+
+---
+
+## Part 1 — Environment, and the traps in it
+
+**Playground:** `/Users/nunomaduro/Work/projects/playground/laravel`
+
+```bash
+cd /Users/nunomaduro/Work/projects/playground/laravel
+GRAPH="$(PAO_DISABLE=1 ./vendor/bin/pest --baseline)/graph.json"   # ~/.pest/tia/laravel-4a455a95622ac0ec
+```
+
+1. **Every** pest invocation needs `PAO_DISABLE=1` — the app has `laravel/pao`, which emits JSON
+   when it detects an agent.
+2. **Never run `git checkout .` or `git checkout -- composer.lock` in the playground.** It has four
+   pre-existing user-modified files — `AGENTS.md`, `CLAUDE.md`, `composer.json`, `composer.lock` —
+   that a blanket reset would destroy. `PLAN.md`'s "reset ritual" is unsafe as written. Scope resets
+   to what you touched: `git checkout -- tests app` / `git clean -fd tests app`, and for
+   `composer.lock` (needed for the drift rows) **copy it aside and copy it back**, verifying with
+   `shasum`.
+3. **`vendor/pestphp/pest` is a dist copy, not a symlink.** Composer installed
+   `dev-fix/tia-filtered as 5.2.0`, so edits in the pest repo do **not** reach the playground.
+
+   **Tell Nuno whenever a sync is needed to move forward — do not sync silently.** Say what is stale
+   and what the sync would be, then wait. This includes temporarily swapping in `db70017c` files for a
+   before/after contrast. When you report any playground result, state which commit produced it.
+   The sync itself, once he agrees:
+   ```bash
+   PEST=/Users/nunomaduro/Work/projects/pestphp/pest
+   V=/Users/nunomaduro/Work/projects/playground/laravel/vendor/pestphp/pest
+   for f in src/Plugins/Tia.php src/Plugins/Tia/Graph.php \
+            src/Plugins/Parallel/Paratest/WrapperRunner.php; do cp "$PEST/$f" "$V/$f"; done
+   ```
+   Verify with `grep -c recordsEdgesInWorkers "$V/src/Plugins/Tia.php"` → `1`. **Always restore the
+   current version before continuing** after a pre-fix contrast.
+4. **Coverage driver:** pcov only, no xdebug. `ini_get('pcov.directory')` is `''` by default — that
+   emptiness is the entire mechanism behind G12.
+5. **Suite shape as found:** 7 tests in 5 files — `tests/Unit/{CalculatorTest,ExampleTest,GreeterTest,
+   TrioTest}.php`, `tests/Feature/ExampleTest.php`. A healthy sequential graph is **`files=22`,
+   5 edge keys, self-edge on every test** (`PLAN.md`'s `files=25` is stale). Pre-fix parallel gives
+   `files=4` with zero self-edges. **These numbers shift the moment you add the Part 1b fixtures** —
+   re-derive them once, after the fixtures land, and use the new numbers throughout. The invariants
+   that do *not* shift: sequential and parallel must agree, and every test must have a self-edge.
+6. **Sentinel patching is the only reliable discriminator** between "wrote identical values" and
+   "wrote nothing": rewrite every cached result to `time=9.999 assertions=42`, snapshot, run the
+   case, diff. A canary test absent from `edges` is unreliable under `--filter` because it never
+   matches the filter and so never runs.
+7. Seeding a cached failure needs `--fresh` (or an env-driven flaky fixture): `--tia` on a clean
+   green tree replays rather than executes, so it can never cache a failure. Working recipe — break
+   an assertion, `pest --tia --fresh`, then restore the source.
+8. Comment-only edits to a test file are **not** changes (AST-level hashing). Use semantic edits.
+9. The shell is zsh — build commands with arrays or `eval`; unquoted `$args` does not word-split.
+
+### Graph summariser
+
+Write this to a scratch path and use it for every diff.
+
+```php
+<?php // summarise.php <graph.json> [label]
+$g = json_decode((string) file_get_contents($argv[1]), true, 512, JSON_THROW_ON_ERROR);
+$files = $g['files'] ?? []; $edges = $g['edges'] ?? [];
+echo ($argv[2] ?? $argv[1])."\n  files=".count($files).'  edges keys='.count($edges)."\n";
+$dirs = []; foreach ($files as $f) { $dirs[explode('/', (string) $f)[0]] = true; }
+ksort($dirs); echo '  file dirs: '.implode(', ', array_keys($dirs))."\n";
+ksort($edges);
+foreach ($edges as $test => $ids) {
+    $self = 'no';
+    foreach ((array) $ids as $id) { if (($files[$id] ?? null) === $test) { $self = 'YES'; break; } }
+    echo sprintf("  %-42s n=%-3d self=%s\n", $test, count((array) $ids), $self);
+}
+foreach ($g['baselines'] ?? [] as $branch => $b) {
+    $r = $b['results'] ?? [];
+    echo "  baseline[$branch]: n=".count($r).' sha='.substr((string) ($b['sha'] ?? '-'), 0, 7)."\n";
+    foreach ($r as $id => $x) {
+        echo sprintf("    %-58s status=%d time=%s asserts=%d file=%s\n", substr((string) $id, -58),
+            $x['status'], $x['time'], $x['assertions'], $x['file'] ?? '-');
+    }
+}
+```
+
+Normalised edge-set equality (for G12 / I5 / K1):
+
+```php
+<?php // edgediff.php <a.json> <b.json>
+function edges(string $p): array {
+    $g = json_decode((string) file_get_contents($p), true, 512, JSON_THROW_ON_ERROR); $out = [];
+    foreach ($g['edges'] as $t => $ids) { $s = array_map(fn ($i) => $g['files'][$i], $ids); sort($s); $out[$t] = $s; }
+    ksort($out); return $out;
+}
+$a = edges($argv[1]); $b = edges($argv[2]);
+echo $a === $b ? "IDENTICAL edge sets\n" : "DIFFER\n";
+foreach ($a as $t => $s) {
+    $m = array_diff($s, $b[$t] ?? []); $e = array_diff($b[$t] ?? [], $s);
+    if ($m || $e) printf("  %s: -%d +%d\n", $t, count($m), count($e));
+}
+```
+
+### Per-case loop
+
+```bash
+git checkout -- tests app 2>/dev/null; git clean -qfd tests app
+rm -rf "$(PAO_DISABLE=1 ./vendor/bin/pest --baseline)"
+PAO_DISABLE=1 ./vendor/bin/pest --tia >/dev/null 2>&1     # seed a healthy graph
+# sentinel-patch every result to time=9.999 assertions=42, snapshot, run the case, diff
+```
+

+
+## Part 1b — Fixtures you must build first
+
+**The playground has none of the fixtures the matrix depends on.** Verified inventory: the only test
+files are `tests/Unit/{CalculatorTest,ExampleTest,GreeterTest,TrioTest}.php` and
+`tests/Feature/ExampleTest.php` — 7 plain tests, zero occurrences of `->group()`, `->only()`,
+`->skip()`, `->todo()`, `->note()`, `->flaky()`, `->covers()`, `->uses()`, `->issue()`, `->pr()`,
+`->ticket()`, `->assignee()`, datasets, or any `FLAKY_OK`-style env hook. `phpunit.xml` defines only
+the `Unit` and `Feature` testsuites.
+
+So roughly 30 rows below cannot run as written until you create the fixtures. Build them **all up
+front, in one commit**, then re-derive the baseline graph shape once and use those numbers for the
+whole sweep — every fixture you add changes `files`, the `edges` key count and `n`, so adding them
+piecemeal invalidates earlier rows.
+
+| Fixture to create | Rows that need it |
+|---|---|
+| a test with `->group('smoke')` | C7, C8, C9, C10 |
+| an env-driven flaky test (passes iff `FLAKY_OK=1`) | E1, E2, E3, E4 |
+| a `->skip()`ed test | E9, D8 |
+| a `->todo()` test | E10, C23, C39 |
+| a risky test (no assertions; pair with `--disallow-test-output`) | E11, D7 |
+| a test that triggers a PHPUnit warning | D6 |
+| a test calling `markTestIncomplete()` | D9 |
+| a test that triggers a deprecation | D10 |
+| a dataset test with ≥3 rows | E13, E14 |
+| `->only()` — added and removed per case, not left in | C31, C32, G7 |
+| `->covers(App\Services\Calculator::class)` | C18 |
+| `->uses(...)` / `UsesClass` annotation | C19 |
+| `->note(...)` | C24 |
+| `->flaky()` **annotation** (distinct from the env-driven flaky test above) | C25 |
+| `->issue(123)`, `->pr(1)`, `->ticket('X')`, `->assignee('X')` | C26, C27, C28, C37, C38 |
+
+This is `PLAN.md` §6's "test-harness gaps to close before re-running", now itemised: without these,
+the listed rows' graph-invariant assertions match zero tests and **prove nothing** — they pass
+vacuously. Any row still marked "(vacuous)" in Part 2 is vacuous *only because* its fixture is
+missing; once you add the fixture, treat the row as unverified and make it load-bearing.
+
+Rows needing an *action* rather than a fixture — breaking `trio one` for the D rows, an uncommitted
+test edit for `--dirty`, branch renames and a non-git dir for H5–H10, `--mutate` against
+`app/Services` for the F rows — are fine as written; `pestphp/pest-plugin-mutate` is installed.
+
+---
+
+## Part 2 — Full case matrix
+
+Tiers: **COMPLETE** may change everything · **RESULTS-ONLY** (RO) may change only
+`baselines[<branch>].results` for tests that ran, and must never remove an entry, add a result for a
+test file absent from `edges`, or alter `sha`/`tree`/`edges`/`files`/`fingerprint` ·
+**HARD-SUPPRESSED** may change nothing.
+
+Phase-1 column: **VERIFIED** = re-run against the fixed code in the phase-one session, pre-fix
+contrast captured · **PASS (sweep)** = passed in the original `db70017` sweep and *not* re-checked
+since the changes — these are the bulk of phase two's work · **SKIP** = not runnable as written.
+
+### A — Setup & sanity
+
+| # | Case | Target outcome | Phase 1 |
+|---|---|---|---|
+| A1 | `composer show pestphp/pest` | version `dev-fix/tia-filtered` | PASS (sweep) |
+| A2 | `pest --baseline` | prints an existing dir; exit 0 | VERIFIED |
+| A3 | delete graph, `pest --tia` | graph.json created; one `edges` key per test file; one result per test | VERIFIED |
+| A4 | `git status` after reset ritual | clean *except the four user-modified files* (see trap 2) | VERIFIED |
+| A5 | `extension_loaded("pcov")` | `true` | VERIFIED |
+| A6 | delete graph, plain `pest` | no graph created | PASS (sweep) |
+| A7 | delete graph, `pest --filter=adds` | no graph created | PASS (sweep) |
+| A8 | two consecutive `pest --tia` | second replays everything; `sha` unchanged | VERIFIED |
+
+### B — COMPLETE runs still write
+
+| # | Case | Target outcome | Phase 1 |
+|---|---|---|---|
+| B1 | `pest --tia` (clean) | replays; graph written; `sha` = `git rev-parse HEAD` | VERIFIED |
+| B2 | `pest --no-tia` | results refreshed; prune applied; `sha`/`tree`/`edges` unchanged | PASS (sweep) — recheck under change 9 |
+| B3 | `pest` (plain) | same as B2 | PASS (sweep) — recheck under change 9 |
+| B4 | `pest --tia --fresh` | graph purged and rebuilt; `edges` rebuilt; `files` repopulated | VERIFIED |
+| B5 | `pest --bail`, all green | COMPLETE — graph written, prune applied | PASS (sweep) |
+| B6 | edit `Calculator.php`, `pest --tia` | `CalculatorTest` re-runs, others replay; `tree` updated | PASS (sweep) |
+| B7 | delete `trio three`, `pest --tia` | its result pruned; `trio one`/`two` remain | PASS (sweep) |
+| B8 | delete `GreeterTest.php`, `pest --tia` | result and edges survive (missing-file prune is `--fresh`-only) | PASS (sweep) |
+| B9 | B8 then `pest --tia --fresh` | entry gone; `files` drops `Greeter.php` too | PASS (sweep) |
+| B10 | `pest --tia` twice | **UPDATED TARGET:** `time` differs only for tests that executed; replayed entries keep their recorded `time`; statuses stable | VERIFIED |
+| B11 | add a test file, `pest --tia` | new `edges` key **and** new result appear in the **same** run | VERIFIED (regression guard for change 9) |
+| B12 | `pest --tia --coverage` | completes; graph written; coverage report prints | VERIFIED |
+
+### C — Selection narrowing → RESULTS-ONLY

+
+### D — Truncation → RESULTS-ONLY
+
+D1–D5, D11–D13, D16 precondition: `trio one` broken. D6–D10 run against a green suite so the `--stop-on-*` trigger is the only narrowing.
+
+| # | Case | Target outcome | Phase 1 |

+### E — Result merge semantics
+
+| # | Case | Target outcome | Phase 1 |

+| J16 | corrupt `graph.json`, `pest --tia` | recovers by rebuilding; no crash | PASS (sweep) |
+
+### K — New rows for the phase-one fixes
+
+These assert behaviour no original row covered. All were verified in phase one; re-run them as
+regression guards.
+
+| # | Case | Target outcome | Phase 1 |
+|---|---|---|---|
+| K1 | healthy `pest --tia` graph, then `pest --tia --coverage` | `edges` **byte-identical** — piggyback data may seed empty sets, never narrow populated ones; `files=22` stays `22` | **VERIFIED (fixed)** — pre-fix: `ExampleTest` 16→2 edges, self-edges lost |
+| K2 | same run's headline | `Experimental TIA mode enabled / recording a coverage baseline.` — no false `fresh graph` | **VERIFIED (fixed)** |
+| K3 | `pest --tia` ×3 on a clean tree | replayed entries keep their recorded `time` across all three | **VERIFIED (fixed)** — pre-fix: `0.053 → 0.001 → 0.001 → 0.001` |
+| K4 | add a test file, one `pest --tia` (graph exists, fingerprint matches → replay+refresh) | result **and** edges appear in that same run; `n` grows by 1 | **VERIFIED** — regression guard for change 9 |
+| K5 | add a test file, plain `pest --no-tia` | no result written for it; `n` unchanged; no edges | **VERIFIED (fixed)** — pre-fix: edge-less result inflated `n` |
+| K6 | `pest --tia --parallel` worker argv | carries `-d pcov.directory=<projectRoot>`; `PEST_TIA` unset; not re-exec'd | **VERIFIED** — probe `bin/worker.php` |
+| K7 | second `pest --tia --coverage` (cache primed → replay) | recorder uses link tracking only, does not clear PHPUnit's data mid-collection; coverage report intact | Not yet measured — **new work** |
+| K8 | `pest --tia --parallel --coverage` | workers read `TIA_PIGGYBACK_COVERAGE`; no widened pcov scope; report intact | Not yet measured — **new work** |
+| K9 | `pest --tia --filtered --coverage-html=<dir>` / `--coverage-clover=<file>` | filtered mode off, same as I8, for every flag in `COVERAGE_REPORT_FLAGS` | Not yet measured — **new work** |
+
+---
+
+## Part 3 — Priorities for phase two
+
+0. **Part 1b fixtures** — nothing in C, D6–D10, or E9–E14 means anything until they exist.
+1. **K7, K8, K9** — the only rows never measured. K7/K8 exercise changes 2 and 3, which were
+   reasoned about but not observed; K9 covers the seven `COVERAGE_REPORT_FLAGS` beyond
+   `--coverage-text`.
+2. **B2, B3, F4** and all of **D** and **E** — change 9 touched the shared result-write path, and
+   these are the rows that exercise it hardest. `$recordsEdges` is the thing to falsify: it must be
+   false for every partial and every non-recording run.
+3. **F3–F8** — change 7 injects a `-d` into worker argv; `--mutate --parallel` is the one place that
+   both spawns workers and must write nothing.
+4. **H1–H10** — untouched by these changes; cheapest bulk confirmation.
+5. Raw PHPUnit coverage flags print **no report at all** in Pest, with or without TIA
+   (`--no-tia --coverage-text` is equally silent). Pre-existing, unrelated to change 6 — do not
+   chase it as a regression, but it means I8/K9 can only assert the selection half.
+
+Report per row: tier respected (yes/no), the graph delta under sentinel patching, and for any
+failure the pre-fix contrast (write `git show db70017c:<file>` into vendor, re-run, restore) so a
+regression is told apart from a pre-existing defect.

+description: "Use this skill for Pest PHP testing in Laravel projects only. Trigger whenever any test is being written, edited, fixed, or refactored — including fixing tests that broke after a code change, adding assertions, converting PHPUnit to Pest, adding datasets, and TDD workflows. Always activate when the user asks how to write something in Pest, mentions test files or directories (tests/Feature, tests/Unit, tests/Browser), or needs browser testing, smoke testing multiple pages for JS errors, architecture tests, or faster test runs with Test Impact Analysis. Covers: test()/it()/expect() syntax, datasets, mocking, browser testing (visit/click/fill), smoke testing, arch(), Livewire component tests, RefreshDatabase, Tia (--tia), sharding, and all Pest 5 features. Do not use for factories, seeders, migrations, controllers, models, or non-test PHP code."

+# Pest Testing 5
+
+## Documentation
+
+Use `search-docs` for detailed Pest 5 patterns and documentation.
+
+## Basic Usage
+
+### Creating Tests
+
+All tests must be written using Pest. Use `{{ $assist->artisanCommand('make:test --pest {name}') }}`.
+
+The `{name}` argument should include only the path and test name, but should not include the test suite.
+- Incorrect: `{{ $assist->artisanCommand('make:test --pest Feature/SomeFeatureTest') }}` will generate `tests/Feature/Feature/SomeFeatureTest.php`
+- Correct: `{{ $assist->artisanCommand('make:test --pest SomeControllerTest') }}` will generate `tests/Feature/SomeControllerTest.php`
+- Incorrect: `{{ $assist->artisanCommand('make:test --pest --unit Unit/SomeServiceTest') }}` will generate `tests/Unit/Unit/SomeServiceTest.php`
+- Correct: `{{ $assist->artisanCommand('make:test --pest --unit SomeServiceTest') }}` will generate `tests/Unit/SomeServiceTest.php`
+
+### Test Organization
+
+- Unit/Feature tests: `tests/Feature` and `tests/Unit` directories.
+- Browser tests: `tests/Browser/` directory.
+- Do NOT remove tests without approval - these are core application code.
+
+### Basic Test Structure
+
+Pest supports both `test()` and `it()` functions. Before writing new tests, check existing test files in the same directory to match the project's convention. Use `test()` if existing tests use `test()`, or `it()` if they use `it()`.
+
+@boostsnippet("Basic Pest Test Example", "php")
+it('is true', function () {
+    expect(true)->toBeTrue();
+});
+@endboostsnippet
+
+### Running Tests
+
+- Run minimal tests with filter before finalizing: `{{ $assist->artisanCommand('test --compact --filter=testName') }}`.
+- Run all tests: `{{ $assist->artisanCommand('test --compact') }}`.
+- Run file: `{{ $assist->artisanCommand('test --compact tests/Feature/ExampleTest.php') }}`.
+- Run only tests affected by recent changes (Tia): `./vendor/bin/pest --parallel --tia`.
+
+## Assertions
+
+Use specific assertions (`assertSuccessful()`, `assertNotFound()`) instead of `assertStatus()`:
+
+@boostsnippet("Pest Response Assertion", "php")
+it('returns all', function () {
+    $this->postJson('/api/docs', [])->assertSuccessful();
+});
+@endboostsnippet
+
+| Use | Instead of |
+|-----|------------|
+| `assertSuccessful()` | `assertStatus(200)` |
+| `assertNotFound()` | `assertStatus(404)` |
+| `assertForbidden()` | `assertStatus(403)` |
+
+## Mocking
+
+Import mock function before use: `use function Pest\Laravel\mock;`
+
+## Datasets
+
+Use datasets for repetitive tests (validation rules, etc.):
+
+@boostsnippet("Pest Dataset Example", "php")
+it('has emails', function (string $email) {
+    expect($email)->not->toBeEmpty();
+})->with([
+    'james' => 'james@laravel.com',
+    'taylor' => 'taylor@laravel.com',
+]);
+@endboostsnippet
+
+## Pest 5 Features
+
+| Feature | Purpose |
+|---------|---------|
+| Tia (Test Impact Analysis) | Rerun only tests affected by recent changes |
+| Time-Balanced Sharding | Split tests across CI shards by execution time |
+| New Validation Expectations | `toBeEmail()`, `toBeUlid()`, `toBeIpAddress()`, and more |
+| Browser Testing | Full integration tests in real browsers |
+| Smoke Testing | Validate multiple pages quickly |
+| Visual Regression | Compare screenshots for visual changes |
+| Architecture Testing | Enforce code conventions |
+
+### Tia (Test Impact Analysis)
+
+Tia reruns only tests affected by recent changes and replays cached results for the rest, dramatically reducing suite duration:
+
+@boostsnippet("Tia Example", "shell")
+./vendor/bin/pest --parallel --tia
+@endboostsnippet
+
+- Replayed tests are not skipped — cached tests store everything they produced, including covered lines and branches.
+- Detects Laravel, Symfony, Livewire, and Inertia automatically.
+
+### New Validation Expectations
+
+Pest 5 ships eight new validation matchers, all supporting `.not` negation:
+
+@boostsnippet("Pest 5 Validation Expectations", "php")
+expect('nuno@pestphp.com')->toBeEmail();
+expect('01ARZ3NDEKTSV4RRFFQ69G5FAV')->toBeUlid();
+expect('192.168.1.1')->toBeIpAddress();
+expect('00:1a:2b:3c:4d:5e')->toBeMacAddress();
+expect('example.com')->toBeHostname();
+expect('example.co.uk')->toBeDomain();
+expect('Zm9vYmFy')->toBeBase64();
+expect('deadbeef')->toBeHexadecimal();
+@endboostsnippet
+
+### Time-Balanced Sharding
+
+Distribute tests across CI shards by execution time rather than count:
+
+@boostsnippet("Pest Sharding Example", "shell")
+./vendor/bin/pest --update-shards
+./vendor/bin/pest --shard=1/4
+@endboostsnippet
+
+Commit `tests/.pest/shards.json` to the repository so CI shards stay consistent.
+
+### Browser Test Example
+
+Browser tests run in real browsers for full integration testing:
+
+- Browser tests live in `tests/Browser/`.
+- Use Laravel features like `Event::fake()`, `assertAuthenticated()`, and model factories.
+- Use `RefreshDatabase` for clean state per test.
+- Interact with page: click, type, scroll, select, submit, drag-and-drop, touch gestures.
+- Test on multiple browsers (Chrome, Firefox, Safari) if requested.
+- Test on different devices/viewports (iPhone 14 Pro, tablets) if requested.
+- Switch color schemes (light/dark mode) when appropriate.
+- Take screenshots or pause tests for debugging.
+
+@boostsnippet("Pest Browser Test Example", "php")
+it('may reset the password', function () {
+    Notification::fake();
+
+    $this->actingAs(User::factory()->create());
+
+    $page = visit('/sign-in');
+
+    $page->assertSee('Sign In')
+        ->assertNoJavaScriptErrors()
+        ->click('Forgot Password?')
+        ->fill('email', 'nuno@laravel.com')
+        ->click('Send Reset Link')
+        ->assertSee('We have emailed your password reset link!');
+
+    Notification::assertSent(ResetPassword::class);
+});
+@endboostsnippet
+
+### Smoke Testing
+
+Quickly validate multiple pages have no JavaScript errors:
+
+@boostsnippet("Pest Smoke Testing Example", "php")
+$pages = visit(['/', '/about', '/contact']);
+
+$pages->assertNoJavaScriptErrors()->assertNoConsoleLogs();
+@endboostsnippet
+
+### Visual Regression Testing
+
+Capture and compare screenshots to detect visual changes.
+
+### Architecture Testing
+
+@boostsnippet("Architecture Test Example", "php")
+arch('controllers')
+    ->expect('App\Http\Controllers')
+    ->toExtendNothing()
+    ->toHaveSuffix('Controller');
+@endboostsnippet
+
+## Common Pitfalls
+
+- Not importing `use function Pest\Laravel\mock;` before using mock
+- Using `assertStatus(200)` instead of `assertSuccessful()`
+- Forgetting datasets for repetitive validation tests
+- Deleting tests without approval
+- Forgetting `assertNoJavaScriptErrors()` in browser tests
+- Prefixing `Feature/` or `Unit/` in `{name}` when using `make:test`
