* fix(process): record withheld unrelated Linux processes as unverified
The token sweep after an owned command (for example the Ghidra Java probe
run by setup and doctor) failed cleanup when an unrelated same-UID process
started during the sweep and Linux denied its /proc/<pid>/environ. Setgid or
setuid programs (mismatched real/saved IDs) and non-dumpable processes are
withheld by the kernel exactly like another account's processes, which were
already recorded as unverified.
Derive the kernel restriction from the same stat-bracketed procfs read that
already supplies the effective UID: all Uid/Gid IDs from status, and the
root ownership procfs reports for a non-dumpable process's environ. Keep that
fact through exit settlement. Related candidates still fail closed.

* fix(process): classify baseline cleanup with current ownership facts
Use the pre-launch baseline only to select candidates for current native
identity/token validation. Preserve confirmed absence and verified foreign
generations instead of carrying a premature baseline identity failure.
Exercise the real Linux enumeration/exit race and retain countercontrols for
unknown identities and live token-owned processes.

* fix(ci): distinguish process inventory from historical PID lookups
* test(ci): verify decoded historical PID controls before tracing
* fix(ci): trace historical PID handles and signal probes
* fix(ci): resolve traced directory paths across pathname syscalls
Classify producer-decoded FD/path pairs once instead of limiting failed relative
lookup detection to openat on /proc. This preserves attempted readlinkat, statx
and newfstatat accesses with no returned descriptor.
Three regression cases fail against the previous policy and all 33 controls
pass with the shared pathname interpretation.

* test(ci): declare unresolved legacy pathname coverage
Report the historical-PID access surfaces actually checked and explicitly mark
legacy cwd-relative pathname calls unverified. The existing tracer does not
provide their cwd identity, and a blanket rejection also rejects legitimate
GDB build-ID metadata queries.
Retain every committed access guard and document the preexisting limit without
claiming absence from missing path evidence. The complete real 44-case CLI/MCP
recorded-crash qualification passes with the coverage declaration.

* fix(ci): reject priority access to historical PIDs
* fix(ci): preserve C-quoted components in traced path checks
strace renders non-ASCII pathname bytes as C octal escapes, not JSON strings.
Keep those components opaque when resolving literal ASCII path separators and
proc PID selectors, matching the existing absolute-path interpretation.
Two controls fail before the correction and all 35 pass afterward. An actual
strace observation independently reproduces the rejection of an unrelated
Chinese filename and verifies the corrected classification.

* fix(ci): reject historical PID resource and scheduler calls
* fix(schema): preserve portable large base64 validation
* fix(ci): share explicit PID syscall contracts with tracing
Derive tracer selection and reported coverage from the same named target
contracts used by the access checker. Cover resource limits, scheduler calls,
process metadata, PID groups, capabilities and pidfd operations without mixing
UIDs, policy enums, self selectors or output values with target PIDs.
Interpret each target once and retain unresolved target facts as a distinct
failure. Emit the coverage catalog once per verifier result.
The previous oracle misses 28 new controls. All 83 controls pass after the
change; real native resource/scheduler probes capture 14 previously missed
calls with resource limits and affinity unchanged. All 35 selected syscall
names are accepted by the pinned local strace.

* fix(ci): classify I/O priority and qualify PID trace coverage
* fix(process): keep ownership retries on the native clock
* fix(ci): retain process edges in ownership trace inventory
Keep fork/vfork and resumed edges along with clone events so the shared attribution owner receives the complete process relation facts it consumes.

* fix(process): type native exit predicates and ownership fixtures precisely
* fix(ci): retain trace coverage limits after integration
Restore explicit unverified symlink aliases and same-Node stat/status purpose in the shared coverage contract and guide. The native-exit and trace-attribution integration does not establish those properties. Preserve both limitations rather than silently broadening the reported qualification.

Settle absent and zombie candidates before retaining baseline or token-read failures. Preserve fail-closed behavior for live and unknown generations, and stop retrying exited candidates.
Bind Linux effective UID to stat-bracketed status reads only for unreadable-token candidates, preserving partial identity facts and avoiding full-table UID enrichment.
Keep a run-scoped evidence owner from acquisition through settlement and
cleanup retry. Bind token observations to native generations and retain
related generations and unresolved identity lookups across table omissions,
reparenting and process-group changes without treating PID hints as authority.
Use native effective UID facts for withholding decisions, corroborate Linux
procfs absence, and share the Linux stat parser with sampling and debugger
identity checks. Signal only after current token and group revalidation.
Complete swept cleanup across all groups with one bounded final family check;
retain unresolved owners and successful-peer completion across retries.
Validation: npm run check, docs:check and test discovery passed. Focused
ownership/consumer coverage totals 513 passed and 1 skipped across 35 files,
including the corrected Electron cancellation test rerun independently. Darwin helper compilation, real
owned Node child cleanup, CLI/MCP capture and retained cleanup retries ran.
Real Electron applications, native Linux races/PID reuse and Windows cleanup
were not qualified. The original Linux reports remain open for that work.

Refs #4322, #5206
Recheck unreadable token and identity observations against one fresh live process snapshot per phase. Preserve token mismatches, fail closed on inspection errors, and retain liveness failure diagnostics.
Validated with focused process ownership, native capture, CLI and MCP boundaries. An eight-member injected-unreadable workload using native ps reduced snapshots from nine to two with equivalent failures; real permission-denied provider behavior was not exercised.
* 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
