morluto 7ee3f236a9 test: replace implementation lock-in with behavioural assertions (#498)
* fix(process): normalize reactive rendered-frame timestamps

A reactive `resize` action stamped `rendered_frames[].at_ms` with the raw
elapsed time while every other rendered frame used
`normalizeProcessElapsedTime`. Under the default 10ms time bucket the next
frame buckets down and appears to move backwards, so `parseProcessCapture`
rejected the entire capture with "rendered_frames: timestamps must be
ordered". No test combined a reactive resize with time bucketing, so the
path was never exercised.

Thread the scenario's bucket into the reactive effect host and normalize the
renderer call, matching what the scheduled-event resize path already did.
`dispatched_at_ms` and `captured_at_ms` stay raw on both paths, so this
changes only the one inconsistent clock.

Also replace the wall-clock-scheduled interactive PTY scenario with
terminal_text triggers. A fixed `at_ms` could fire before the child wrote
its prompt under host contention, dropping the input and the resize echo.
That rewrite is what surfaced this bug, and it now passes deterministically.

Replace the 11 `if (!capability.available) return;` guards across the PTY
suite with a shared it.skipIf gate. The old form reported a green pass with
zero assertions on any host lacking native PTY authority; skips are now
named and reported.

Verified by reverting only the normalization, which reproduces the
validation failure immediately.

* fix(install): add recovery guidance to version-mismatch failure

Every installer failure except one told the user what to do next. The
version-mismatch failure reported only that the installed version did not
match, with no remedy, which contradicts the requirement to keep
diagnostics actionable for mismatch locations.

Add a remedy in the same style as the neighbouring failures and drop the
exemption the test carried for it, so all ten installer failures now assert
they carry a recovery action.

* ci: repair stale curated Windows lane and unblind the duplication gate

The `windows-curated` job listed fifteen test files and nine of them no
longer existed, including six `processOwnership*` files moved to
`src/process/` in 4ecc7a72. Vitest silently drops unmatched paths, so the
job ran six files and reported success. Repoint the paths at their current
locations and add a test that fails when any listed path is renamed or
removed, so the lane cannot silently lose coverage again.

The duplication gate ignored `**/*.test.ts`, so it reported zero clones
across the test tree while running on every PR. Include test files, remove
the two largest duplicated clusters, and ratchet the threshold to the
measured result so the gate can no longer pass by not looking.

Run local tests with two workers instead of one. A single worker made a
full local run cost ~140s of wall time at ~100% CPU on a 10-core host,
which was the largest dev-cycle cost in the repository. Local now matches
the concurrency CI already proves green, and PTY scenarios moved to a
serial project because they contend for host terminal resources. Full local
suite: 140s to ~89s.

Regenerate the managed conformance manifest. Commit 4ecc7a72 edited
SKILL.md without refreshing the digest, so `npm run check:pr` has been
failing on main since that commit.

* test: replace implementation lock-in with behavioural assertions

Audit the suite for tests that cost maintenance without catching defects,
then remove the lock-in rather than the coverage.

Replace assertions that froze incidental detail:

- toolContracts.test.ts pinned group sizes and 50 lines of literal tool
  names, so any additive catalog change required a test edit. Replace with
  four structural invariants: global name uniqueness, group containment in
  the published inventory, group disjointness, and non-empty groups. Both
  invariants are mutation-checked by orphaning and duplicating a tool.
- Six tests asserted only that a schema accepts its own canonical fixture.
  Replace five with real rejections and two with property tests covering
  the invariants those tests were gesturing at: `isDbSaveComplete` is
  downward closed in every expected count, and frame retention holds at
  any size.
- A concurrency test whose fake returned `? [] : []` could not fail. Give
  the fake real shared state so a lost update is observable.
- providerProcess.test.ts asserted listener and timer counts plus exact
  cleanup retry counts. Assert detachment behaviour instead, so an
  unrelated internal timer no longer breaks the test.
- Scale tests that rebuilt removed caps: 16 MiB and 10,001 files to prove
  limits that no longer exist, 100,001 frames compared against their own
  length, and a projection asserting a literal 10,201 bridge candidates.
  Replace with derived relationships that hold at any size.
- installScript.test.ts merged two tables and now asserts alongside the
  exact wording that every failure carries a recovery action.
- cdpBrowserProvider.sensitive_data asserted outcomes produced after the
  observation window closes while using a zero-length window; give it a
  real window so it measures the malformed-body rejection rather than host
  speed.
- runtime.test.ts repeated the catalog assertion from the MCP boundary
  suite while spawning a second stdio server. Give the database-kind
  scenario its own claim and make stale-build failures legible.

Extract two byte-identical fixture preambles that the max-lines rule had
split across five and three files respectively, removing ~1,000 duplicated
lines.

Profile the heaviest files rather than only running them: the Apple
projection test drops from 6.4s to 0.28s and the reference source import
from 2.3s to 0.2s, with stronger assertions in both cases.

* ci: keep native-authority suites out of the curated Windows lane

CI showed the repointed curated list was red. Three of the restored files
require verified Windows native authority, which windows-latest does not
provide by design:

- src/ghidra/GhidraProvider.test.ts, the replacement for the deleted
  tests/boundary/providers/ghidra/ghidraProvider.test.ts
- tests/boundary/providers/ghidra/ghidraClient.test.ts
- tests/boundary/process/providerProcess.test.ts

All three fail with PrivateRuntimeRootUnavailableError, because Job Object
process ownership and private-runtime DACL enforcement are unimplemented.
The previous ghidraClient and providerProcess entries were added in this
branch and never belonged here; the GhidraProvider replacement does not
inherit the deleted file's Windows behaviour.

Those claims belong behind the same approval boundary as the real Ghidra
Windows workflow rather than the default lane. Record the exclusion in the
guard test so the lane cannot regress to red, and in ci.yml so the next
reader knows the omission is deliberate.

The lane now runs 14 files, up from the 6 it silently ran before, all
verified green on windows-latest.

* test: stop max-lines from forcing test files to split

The 500-line cap on test files only ever produced duplication. It chopped one
binary session suite across nine files whose names were truncated
mid-sentence, and it is why the curated Windows lane referenced six
`processOwnership*` paths that had been split apart in the first place.

Turn the cap off for tests and fixtures, keeping the function-length limit,
then merge the nine binary session files back into one suite. That restores
all 22 cases under a single module registry instead of nine and cuts the
composition project from 20 files to 12. The merged cases become nine
top-level describes grouped by concern, because a single wrapping describe
would itself breach the function-length limit.

Drop applicationWorkflowVerifier.test.ts. Its first case asserted
`verified: true`, which the script emits as a literal after its own checks,
so it could not fail, and every remaining assertion was `expect.any`. Its
second case asserted an export-shape comparison that
applicationWorkflowCli.test.ts already asserts through the product CLI,
which is the stronger claim.

Finally, five javascriptSemanticAnalysis files imported `it` from
@fast-check/vitest while containing no properties. Import `it` from vitest
so those files no longer read as property-based coverage.

* test: stop creating temp scaffolding the temp helper immediately deletes

`createTestTempDirectory` called `createTestWorkspace`, which creates `home`
and `xdg/{config,cache}`, then deleted two of those three directories so the
caller would receive an empty root. Every caller paid three `mkdir` calls and
two `rm` calls per temporary directory for scaffolding it never used, across
roughly a hundred test files.

Create the directory directly instead. Callers that genuinely need a home or
XDG tree can call `createTestWorkspace`.

* test: merge the split process reactive runtime suite

Five files shared one describe name in pairs and re-imported the same fixture
helpers. With the shared preamble already extracted into
processReactiveRuntime.fixture.ts, merge them into one suite of five
top-level describes grouped by concern. All 12 cases are preserved and the
domain project drops from 92 files to 88.

* test: drop two identity round-trips from node runtime characterization

One test built a plan with `max_calls: 10_001` and asserted the field came
back as 10_001, which asserts that the plan constructor copies a field the
test just set, and freezes a former ceiling in the process.

The other built a 201-character alias and asserted it parsed back to the
same string, which round-trips a value the test created.

Neither could fail for a reason that matters. The remaining cases still
cover preparation, stale-plan rejection, single dispatch, and artifact write.

* test: hoist duplicated graph fixtures into the shared fixture module

Eleven copies of three helpers were spread across the seven
javascriptApplicationGraph files: `completeCoverage` five times,
`nodeByLabel` four times, and `firstOf` twice, all byte-identical. The
fixture module already carried a private `completeCoverage`.

Export all three from javascriptApplicationGraph.fixture.ts and import them,
removing 95 duplicated lines.

* test: separate the reactive fixture's two PTY writes

The multi-source run resolved target_lost instead of passed intermittently.
The ready transition matches terminal text "Ready" and consumes that
observation, advancing the terminal frontier; the collecting state then
needs "Collecting" in a later observation. The fixture wrote both back to
back, so the PTY sometimes coalesced them into one chunk and the collecting
trigger could never match.

Move the "Collecting" write after the synchronous shim probe. The probe takes
real wall time, so the reader has drained the first chunk before the second
is written, which makes the ordering deterministic rather than timing
dependent.

Measured 33/34 isolated passes, against roughly even odds before. Under four
concurrent copies it still failed 2 of 12, so this narrows the window rather
than closing it: the underlying race is that node-pty delivers buffered
output through a callback the exit path never awaits, so the harness can
declare the target lost before the last chunk is ingested. The test is left
strict because it is correctly detecting that.

* test: replace expect.any placeholders with real results

Four acceptance scenarios and one composition scenario asserted only that a
field was a string, number, object, or array. Those assertions cannot fail
for a reason that matters, and three of them sit behind real CLI process
spawns that cost about 1.5s.

Capture the actual results once and assert them exactly. The CLI parity
scenario now pins the trace summary and coverage, the version comparison
summary and coverage, and the source-to-bundle summary and coverage, so each
spawn earns its cost. The MCP rejection case now asserts `invalid_request`
with category `invalid_input`, which is what makes it a caller-input failure
rather than a provider one.

The artifact comparison case asserted three `expect.any` values immediately
before an assertion that subsumed them. Replace them with the claim that
actually matters above 500 entries: manifest counts must reconcile with the
arrays returned, and every written file must appear as an occurrence, so a
reintroduced truncation would fail.

* test: remove impossible and incidental prompt assertions

Two assertions in toolResult could never fail: each asserted that the
serialized result did not contain a string that appears nowhere in its own
inputs, so only in the assertion itself.

promptContracts asserted that a `Set` built from a locally declared six
element literal had no duplicates, and pinned thirteen incidental fragments
of rendered prompt prose. Drop the tautology and reduce the prose block to
the five properties an analyst actually depends on: caller input framed as
data rather than instruction, tools offered as options rather than a
mandated sequence, the epistemic vocabulary present, tools never framed as
authorization, and deterministic suggestion order.

* test: hoist the remaining duplicated graph fixtures

Eight more byte-identical helper copies across the javascriptApplicationGraph
files: `graphForNode` four times, `unknownEvidence` twice, and `contentNode`
twice. Move them into javascriptApplicationGraph.fixture.ts alongside the
three hoisted earlier, and drop the imports they left behind.

Net -92 lines across the seven files.

* test: drop enhancedTools helpers already in the shared harness

Three of the six enhancedTools files still carried local copies of
PROCEDURES, inventory, and emptyBounded that are byte-identical to the
exports added to enhancedToolsHarness.ts. Import them instead.

Only fixturePort, connect, and jsonResult differ per file, so those stay
local.

* test: replace repeated process-tree event literals with fixture builders

The file spelled out nineteen thirteen-field event literals and thirteen-field
process nodes inline, varying only three or four fields each, so a test read as
a wall of repeated boilerplate rather than the transitions under test.

Add eventProcessTree.fixture.ts with spawn, exit, re-exec and reparent
builders plus a process-node builder, and express each case as the sequence it
describes. The test drops from 422 to 214 lines with all nine cases intact.

* test: share the process-ownership validation fixtures

The two process-ownership validation files each declared byte-identical copies
of an `ownership` constant and a 24-line `host` builder. Move both into
ProcessOwnership.fixture.ts and import them.

* test: make rejection and retention assertions exact

The reactive scenario rejection table asserted only that each of its six
fixtures failed to parse. A typo anywhere in a fixture would satisfy that,
including one that invalidated an unrelated field. Record the field each row
is meant to invalidate and require the reported issue to point at that path
with the expected code. Verified by making one row valid except for an
unknown key: the row now fails instead of passing for the wrong reason.

The large-body replay test asserted that the serialized result exceeded five
million characters as a proxy for the bodies being retained, which escaping
or padding could satisfy even under truncation. Compare each retained body to
the input byte for byte and total the retained length. Verified by shaving one
byte off the expected value, which now fails.

* test: share the elicitation grants fixtures

The three processCaptureElicitationGrants files each declared the same five
helpers inline: an elicitation request, a fixed clock, a ceiling-only
permission authority, a request-context builder, and a verified-state stub.
Move them into elicitationGrantsHarness.ts and import them.

* fix(process): wait for trailing PTY chunks before declaring target loss

The exit path drained the reactive coordinator and then submitted
target_lost, but node-pty delivers buffered output through onData callbacks
that run outside the coordinator's queue. A trailing chunk that had not been
delivered yet produced no journal entry, so the drain had nothing to wait for
and the target was declared lost while a terminal trigger was still
satisfiable. That is what made the multi-source reactive fixture resolve
target_lost instead of passed at roughly even odds.

Yield to the event loop until the capture journal stops growing before
draining, bounded so a pathological stream cannot stall exit.

The fixture change that accompanied this is no longer carrying the weight on
its own; the ordering it introduced remains correct and worth keeping.

Measured 18 consecutive passes across isolated and four-way concurrent runs,
against roughly even odds beforehand. A control run with the wait disabled did
not reproduce the failure, so the machine was not loaded enough for a
controlled comparison; the before/after numbers are from separate sessions.

* test: hoist the last duplicated domain and coordinator fixtures

processTraceComparison and its Part2 declared the same eight helpers, and the
two ProcessReactiveCoordinatorFailures files declared the same three. All were
byte-identical. Move them into shared fixture modules and import them, netting
429 fewer lines.

The earlier attempts at this failed because depth-based scanning mis-detected
helper boundaries: bracket characters inside type annotations, such as
`options: { truncated?: boolean }`, unbalance the count. Extracting by verified
line range instead worked first time, and unused imports were then settled by
alternating typecheck and lint rather than by guessing which names a body uses.

* ci: ratchet the duplication gate to the reduced baseline

Test-file duplication is down to 2.58% of lines across src and tests, from
3.39% when tests were first included in the gate. Lower the threshold from
3.2 to 2.7 so the reduction cannot regress.

* test: merge the remaining artificially split test files

Five suites were each split across two or three files by the max-lines rule
that is no longer applied to tests, and every split produced a duplicate
describe name and a duplicated import block.

Merge them back: processTraceComparison, ProcessReactiveCoordinatorFailures,
ProcessOwnership.validation, processCaptureElicitationGrants, and
processCaptureElicitation. Net -62 lines and five fewer files.

Give each merged describe a name describing what it covers, since the splits
were arbitrary and the names now collide. Test bodies are unchanged; every
describe already fitted the function-length limit, so merging them as
separate top-level blocks satisfies it.

Imports were settled by writing each block explicitly after typecheck and lint
disagreed. Lint is right about names that appear only inside string literals,
such as `values(["terminal", "process", "http", "websocket"])`, while
typecheck is right about names a body genuinely references, so neither alone
was sufficient.

* test: merge the graph suite and share the enhancedTools result helper

The seven javascriptApplicationGraph files were one suite with one describe
name repeated seven times. Merge them into a single file with seven
describes named for what each covers, keeping all 18 cases.

Three of the enhancedTools files declared byte-identical copies of a
jsonResult helper. Move it into enhancedToolsHarness.ts alongside the rest of
the shared fixtures.

The remaining enhancedTools files stay split: their fixturePort helpers are
three genuinely different provider doubles rather than duplicates, so merging
them would mean renaming per-file seams and lose the reason each exists.

* ci: repoint the Windows lane at the merged ownership validation file

Merging the split ProcessOwnership.validation files removed the two Part
paths the curated Windows lane referenced. The curated-lane guard test caught
it on CI, which is the failure it was added to prevent.

* test(process): make lifecycle assertions falsifiable and scope them to POSIX

Two assertions could not fail, so neither observed the behaviour it claimed.

The deadline disposal test aborted an already-aborted controller and then read
an immutable interruption, so it passed whether or not disposal released the
timer or the listener. Dispose before aborting instead and assert the owned
timer count reaches zero, which distinguishes a released deadline from a
retained one. Verified by mutation: emptying dispose, dropping the listener
removal, and dropping the timer clear each fail the test.

The supervisor test asserted that a repeated stop still resolved, but stop
caches its promise, so it proved nothing about detachment. Replace it with a
late error and close event after disposal and assert the diagnostic channel
stays untouched, keeping an attached control that proves the channel works.
Verified by mutation: retaining the error listener fails the test.

Also mark the TERM-to-KILL escalation POSIX-only. libuv maps every signal to
TerminateProcess on Windows, where a child that ignores SIGTERM cannot survive
the TERM step, so the escalation and SIGKILL signal code are unreachable there.

* fix(vitest): restore cross-project scheduling for local runs

Dropping the per-project `sequence.groupOrder` made every project run
concurrently. `fileParallelism: false` only serialises files inside a single
project, so `process-boundary` could still overlap with the boundary projects
that observe host process and terminal state, which is the contention that
drops input and resize echoes. The removed blanket per-project serialisation
was slower, but it was never what isolated projects from each other.

Keep the two-worker intra-project parallelism that made local runs fast and
apply the ordering locally only, so CI keeps the concurrency it proves green.

* fix(acceptance): make the database startup record check observable

The check asserted stderr contained no fatal record, but a database-kind
startup that only lists the catalog starts no bridge work and writes no
records at all, so the assertion passed without observing anything. Reading
stderr while the child was still running also raced the pipe, and splitting
the buffer could parse a partial trailing line.

Call a tool so startup records are actually produced, parse only complete
newline-delimited records, and read after the transport closes so delivery is
no longer in question. Guard the result with an explicit non-vacuity assertion
so the fatal check cannot silently stop observing anything.

Verified by mutation: injecting a level-60 record through the stderr logger
now fails the test.

* test(acceptance): restore the application workflow verifier coverage

Nothing else in the repository executes
scripts/verify-local-application-workflows.mjs, so deleting this file left the
only automated check on a shipped script. Regressions in its dist imports,
argument handling, or two-version and export-shape output could ship with a
green suite.

The two cases cost about 350ms and 500ms, so the duplication that motivated
removing them was never the reason to drop the coverage.

Verified by mutation: flipping the reported verification status fails the
suite.

* test(contracts): add a published tool name floor

Every remaining inventory invariant is structural, so deleting a contract from
both its group and the aggregate left the whole file green while the catalog
regenerated without it. Structural checks cannot detect removal; only a
declared baseline can.

Declare the 114 published names as a floor rather than an equality. Adding a
tool still needs no edit, while removing one now fails with a message naming
the tool. Verified by mutation: dropping a contract from its group so the
aggregate loses it too fails the floor.

* test: restore no-ceiling coverage above plausible truncation limits

Four suites claimed a result was complete at any scale while their own inputs
were bounded below where a truncation would appear, so the guarantee they
described was not actually under test. Scale independence cannot be asserted as
a relationship over a fixture smaller than the cap being ruled out.

Raise each fixture past any ceiling a regression would plausibly introduce,
which is far cheaper than the removed cases:
  referenceSourceImport  600 entries/64 KiB -> 5,000 entries with a 4 MiB member
  customProtocolCapture  generated max 40 frames -> 300..1,000
  appleApplication       12 frameworks/16 candidates -> 250/1,600
  nodeRuntimeCharacterization  assert the absent call-budget and alias bounds
    where they would be added, since the budget derives from the case count

Verified by mutation: a 1,000-entry import cap, a 500-frame capture cap, a
100-framework projection cap, a 100,000-call budget cap, and a 200-character
alias cap each fail the corresponding suite.

* fix(process): require a quiet period before declaring the target lost

Returning on the first unchanged journal sample granted a single event-loop
turn of grace. A chunk queued on a later iteration therefore still let
`target_lost` be submitted before the final terminal observation, discarding a
satisfiable reactive trigger under the same load-dependent exit scenario the
drain was added for, and `maxTicks` never bounded that because the loop exited
early every time.

Require several consecutive unchanged turns so a callback arriving on any of
the next few iterations still lands first, while keeping the overall tick bound
so a pathological stream cannot stall exit.

* fix: stop a 4 GiB fixture and measure the drain quiet period in time

The reference import fixture cycled its five sizes across all 5,000 entries,
which made a thousand 4 MiB members and nearly 4 GiB of fixture written
concurrently. It happened to fit locally but cannot fit a runner's disk. Cross
the two boundaries independently instead: entry count by volume of tiny
members, byte size by a single 4 MiB member, for about 4.2 MiB total. Verified
by mutation that a 1,000-entry cap and a 1 MiB per-member cap both still fail.

The drain check counted scheduler turns, but consecutive setImmediate turns
elapse in microseconds, so four of them finish long before a pty callback
delayed under host contention, which is when the trailing chunk matters.
Measure the quiet interval in elapsed time instead, so a late callback within
the window still lands before target loss. Verified by simulation: the
turn-count version missed any delay beyond a few microseconds, the timed
version observes delays up to the quiet interval.
