Retain unresolved process identity and launch evidence through retryable cleanup. Share capture path normalization and preserve failed filesystem observations. Bound child output and drain Windows pipes without one-chunk throttling.
Reviewed fixes include #1628, #2632, #2644, #2784, #2928, #2931, #2965, #2992, and #3011.
Validation: 92 focused source tests passed; four platform-specific skips. Real Windows and Hopper lifecycle coverage was not rerun.
* fix(process): order interaction differences by their dispatch time
first_divergence ranks candidate differences by the earliest recorded
time of the differing observations, but eventTime read only `at_ms`.
Interaction events record their time as `dispatched_at_ms`
(and `scheduled_at_ms`), so a changed interaction always ranked as
untimed. An interaction outcome that differed at 6 ms therefore lost to
a process sample that differed at 500 ms.
Give each comparison dimension its recorded time field. Interactions use
the dispatch time, when their outcome was observed; the other
dimensions keep `at_ms`. An earlier process difference still wins.
Fixes#2645

* fix(process): require ordered interaction dispatch times in captures
Comparison ranks a changed interaction by its dispatch time, while
firstCollectionDivergence returns the first differing interaction by
sequence. The capture parser checked only that interaction sequences are
contiguous, so an imported capture whose dispatch times decrease could
make that first-by-sequence difference later than another differing
interaction.
Interactions are dispatched in sequence and their times come from the
monotonic capture clock, so require non-decreasing dispatch times at
parsing, as frames, rendered frames, process samples and filesystem
checkpoints already require for their timestamps.

Declare the synthetic 4 KiB Mach-O slice alignment accurately while preserving the IDA thinning scenario. Share web cleanup aggregation and process-trace fixture facts instead of duplicating them across consumers and tests; keep the 3% duplication threshold unchanged.
Validation: npm run check:ci, test discovery, and 42 focused IDA, process-trace, web workflow and cleanup boundary tests. Duplication falls from 3.01% to 2.99%.
The trace specification owns the declared identifier vocabulary and the
comparison result echoes those identifiers verbatim into raw_trace[].event_id,
matched_variant and diagnostic event_ids. The result module restated the shared
IDENTIFIER_PATTERN by hand with a 64-character cap, so a specification with a
longer identifier validated and then its own comparison result failed to parse:
compareProcessTraces threw a raw ZodError at the caller instead of returning a
comparison.
Export the identifier schema from the specification as the single owner and
reuse it in the evaluation module, removing the capped copy. IDENTIFIER_PATTERN
has no length bound and every other consumer uses it unbounded, so the
duplicate was the outlier. Removing the bound rather than adding one keeps the
advertised trace_spec input contract unchanged; identifiers of 64 characters or
fewer behave exactly as before.
Verified with 48 process tests, 24 boundary CLI/MCP trace tests, check:fast and
verify:test-discovery on macOS arm64. The regression test failed with the
ZodError before the change and passes after it.

Prove total orders with Kahn traversal and use ranks; stream forward and reverse reachability for general partial orders instead of retaining every closure. Aggregate unordered conflicts by declaration while preserving missing-pair counts and independent malformed-input diagnostics.
Validation: 33 focused trace domain and CLI/MCP boundary tests passed. Six bounded Flameox executions preserved answer digests and cycle rejection; combined median peak RSS fell from 391.13 to 127.72 MiB. General partial-order traversal costs more CPU; the experiment records that tradeoff. Full suite and real-provider lanes were not run.
Use iterative cycle detection, memoized reachability and compact unordered-group membership. Preserve declaration diagnostics on cyclic input while skipping checks requiring a valid partial order. Report duplicate group declarations once instead of repeating pair errors.
Replace redundant source cycle/missing-pair assertions with public CLI/MCP coverage including 6000 events, dense not-before constraints and a large unordered group. Validate acyclic branching and mixed relation semantics. Document bounded Flameox CPU/latency gains and higher observed peak memory; agent/model costs remain unmeasured.
Summarize incomplete trace-specification pair declarations with exact counts and the first undeclared pair. Preserve complete pair coverage, successful Evidence and independent validation errors; remove temporary pair-scan copies and sorting.
Closes#1753.
* fix(build): emit no runtime imports for type-only bindings
Under verbatimModuleSyntax, an import whose specifiers all carry inline
`type` modifiers compiles to `import {} from "..."`, a side-effect import
that still resolves and evaluates the module. 78 compiled modules carried
one, including `import {} from "playwright-core"` in the browser scenario
session, which loaded Playwright's module graph at MCP startup.
Use top-level `import type` for these bindings and enable oxlint's
typescript/no-import-type-side-effects rule so the pattern cannot return.

* perf(mcp): load Playwright when a scenario launches, not at startup
The browser scenario and Electron active providers are constructed before
the stdio server serves, and both bound Playwright's launchers at module
load. Resolve `chromium` and `_electron` from playwright-core when a
capture opens instead, as the web module resolver already does.
MCP startup now resolves 1,312 modules (4,902 resolutions) instead of
1,598 (6,076) before reading the first request, and no longer loads
playwright-core. Provider construction, the tool catalog, and capability
inventory are unchanged.
A boundary test spawns the stdio server, initializes, lists tools, and
asserts playwright-core and isomorphic-git were not resolved; the CLI
probe now exercises the real launch path to prove detection.

Validate columns × (rows + scrollback) against a 1,000,000-cell xterm working-buffer budget, including every resize with the selected scrollback. Document the budget in the advertised MCP input and process-capture guide; never clamp caller dimensions.
Validation: default/exact-boundary schema cases, prelaunch MCP rejection, compiled CLI capture, terminal rendering, normalization, cancellation, and lifecycle checks pass on macOS. This is resource admission, not a measured serializer throughput improvement; Linux-only and real deep-analysis providers were not exercised.
BREAKING CHANGE: process scenarios whose initial or resized terminal exceeds 1,000,000 combined visible-plus-scrollback cells are now rejected before launch.
Keep caller-selected replacement text literal with a callback, preserving
empty-search positions instead of changing their split/join behavior.
Commit the replacement interpretation for captures using custom patterns so
legacy records cannot report this producer correction as a target change.
BREAKING CHANGE: Captures with custom normalization patterns use
literal-replacements-v1 and cannot be compared with legacy unversioned
pattern captures. Capture both sides with the same replacement semantics;
legacy captures remain readable and captures without patterns are unaffected.
Rendered frames padded every visible row with trailing spaces to the
terminal width. Blank rows cost a full row each and every frame repeats
them, so the padding made up 14-39% of capture Evidence (2 KB of sparse
output produced 228 KB). The padding carried no information: columns is
recorded and serialized_state keeps the exact terminal state.
Lines are now trimmed after normalization, so line.padEnd(columns)
restores the previous value. The comparison contract commits
rendered_line_format so older padded captures do not compare as the
same contract.

BREAKING CHANGE: Filesystem digest omission entries now require system_code; budget and changed-file omissions use null, and unavailable-file omissions preserve the operating-system error code.

Require process retention accounting, browser network transaction identity, and all web comparison dimensions. Remove obsolete omission repairs and derive completeness from the owning producer facts.
BREAKING CHANGE: Historical captures without current producer accounting or transaction identity, and web diffs missing accessibility or storage dimensions, are rejected.
trace_dylib_resolution roots and capture_process_scenario environment
names still advertised negative look-ahead patterns. RE2 and Rust schema
validators reject look-around, so a client using one refuses the whole
tools request, as #1282 reported for the NUL escape. Spell both
constraints as equivalent look-around-free patterns and assert that no
advertised pattern uses look-around or backreferences.

parseProcessCapture accepted terminal retention accounting that its
retained frames contradict: any retained_bytes within budget, and
observed_bytes above retained_bytes with no omitted frame. A malformed
capture could therefore report truncated: false while its terminal
evidence was incomplete. Recompute retained raw and rendered bytes from
the frames, and require equal observed and retained bytes when no frame
was omitted.

Contextual port normalization refused any port followed by a period, so
common log lines such as "Listening on port: 8080." or
"http://localhost:8080." kept their run-specific port and equivalent
captures compared as changed. Accept a sentence-ending period while
still refusing a period that continues a decimal, version, or host name,
and bump the committed port-normalization version.

Remove getter, enum, cloned-projection, cache-identity, and obsolete profile assertions along with the shadow JSON Schema engine and dead test-only APIs. Retain producer, filesystem, SDK, lifecycle, integrity, and malformed-format coverage.
Document the priority of real end-to-end workflows, boundary integration, and producer goldens.
Remove v3 capture conversion and require explicit executable identity and event journals. Preserve cancellation, execution diagnostics, snapshots, and cleanup outcomes from preparation through CLI delivery.
Separate exhausted path enumeration from hash coverage and preserve known

* refactor(schemas): share identifier and canonical base64 patterns
* test: hold the offset datetime schema to the validator it replaces
The module documents that its accepted set matches z.string().datetime({ offset: true }), and nothing in the suite checked that claim. Adds table-driven accept and reject cases (leap years including the 1900/2000 century pair, month, day, hour and offset ranges, fractional and omitted seconds, missing offset, basic format) plus a differential assertion that classifies every case exactly as the replaced validator does, and asserts the emitted pattern compiles under u and v while the replaced pattern does not compile under v.

* fix: emit v-mode-compatible patterns for tool schemas
Character classes in emitted patterns carried unescaped '-', '/' and '['. Annex-B and u-mode accept them, so REA's own Zod validation (u) and every u-based validator never saw a defect, but v-mode rejects ClassSetSyntaxCharacters and Ruby rejects [^s[]]. With 6.1.0 tools/list, 117 pattern fields across 11 tools were rejected under v.
The characters are escaped as \x2d, \x2f, \x5b and \x5d rather than \-/\//\[, because oxlint --fix removes an escaped '-' inside a character class as a useless escape, so an escape-only change does not survive the pre-commit hook. \x2d-style escapes are valid under Annex B, u and v, are matched identically, and are not useless-escape candidates.
22 pattern literals in 18 files are touched; no other token changes.
* fix: replace the Zod offset pattern and guard the advertised catalog
The offset datetime site projected Zod's offset class as [ +- ], which no escape in this repository's sources can reach, so evaluate_reconstruction_coverage stayed unreachable for exactly the clients this change targets. It now uses offsetDateTimeSchema in src/domain/offsetDateTime.ts: the same accepted set with the offset class escaped as [ +\x2d ].
Adds tests/boundary/mcp/advertisedPatternsVMode.test.ts, which performs the real tools/list projection, traverses every advertised input and output schema, compiles each pattern under v, and asserts the inventory it walked so a silent traversal collapse fails instead of passing vacuously.
* fix(process): name the reason two captures cannot be compared
compare-process-captures rejected captures whose comparison contracts
differ, but the reason never reached the caller. The CLI printed
"Process command could not complete... run `rea doctor`". MCP wrapped
the error in an AnalysisInputError with no issues ("Analysis input is
invalid. Check the arguments"). A stale capture under
max_capture_age_ms got the same treatment.
Throw typed input issues that name the differing contract fields, or
the stale side with its completion time and age, and let
runDerivedOperation pass AnalysisInputError through unchanged. Document
what the comparison contract covers.

* fix(process): report CLI trace-spec issues under the MCP input path
The CLI reported an invalid trace specification under operation
"compare-process-captures" with root-relative issue paths such as
["events"]. MCP reports the same input as compare_process_captures with
paths under trace_spec. Use the canonical operation name and prefix
trace_spec so both surfaces describe the same input identically.

* fix(process): name the side and constraint for unusable capture Evidence
Adjacent compare_process_captures failures still lost their reason.
Over MCP, Evidence from another workflow, tampered Evidence and an
invalid capture result all became "Evidence is invalid or has changed".
The CLI said only "Capture evidence is malformed".
Parse each side separately. Evidence from another workflow is an input
issue on left or right that names the operation and predicate it has.
Tampered Evidence and invalid capture results stay integrity
mismatches, and their message now carries the validation detail.

* fix(process): stop failing captures on tokens macOS cannot expose
On a busy macOS 26 host the residual process sweep fails every capture:
KERN_PROCARGS2 omits the environment of Apple platform binaries for any
caller and fails with EINVAL for processes owned by another account, so an
unrelated process created after the capture baseline escalates to a hard
cleanup failure with cleanup_incomplete.
Report environment withholding distinctly from the Darwin token reader by
reading the platform-binary flag through csops, carry the effective uid in
the process table, and re-read unresolved tokens with a bounded retry plus a
final liveness confirmation so transient exec and exit states settle.
Candidates whose token the OS provably withholds, foreign-uid candidates,
and candidates that exited during validation are now recorded as unverified
processes instead of failing an otherwise clean capture or being signaled.
Related candidates and every other unreadable candidate stay fail-closed.
* test(process): align ownership lanes with the uid-aware process table
The Darwin sweep reads the effective uid through ps, so the offline
verification lanes' syscall allowlists must accept the new argv in
verify-binary-layout and verify-evm-interface. The foreign-uid ownership
test requires POSIX process uids; skip it where the platform has none
(the curated Windows lane).
* fix(verify): recognize UID-bearing ownership process tables
