@src/common/platform/include/aicpu/diagnostic_run_terminal_aicpu.h:
- Around line 62-64: In the publish path, add a release barrier between
diagnostic_terminal_store_counts and diagnostic_terminal_commit so the epoch
becomes visible only after the counters. Keep the existing barrier after the
commit.
Review comments at @src/common/platform/include/host/pmu_runs.h:
- Around line 917-925: Update the `run_close` record-snapshot logic so
`snapshot_run_records_from_terminal` runs only when `device_execution_complete`
is true. For incomplete runs, leave `epoch.terminal_bank` unsettled and assign
empty `RecordProofs`; keep the existing `snapshot_run_records` path for owners
that do not publish run terminals.
- Line 1599: Update the PMU and ArgsDump withdrawal paths to release each
epoch’s terminal-bank reservation under the corresponding mutex before releasing
its slot. In pmu_runs.h:1599-1599, call terminal_bank.release() in
withdraw_unpublished_slot and on abandon_run’s proved-released path before
release_slot. In args_dump_retained_runs.cpp:1373-1373, do the same in
retained_withdraw_unpublished_slot and abandon_run before retained_release_slot;
do not release the reservation in retained_release_slot itself.
Review comments at @src/common/platform/shared/host/dep_gen_retained_runs.cpp:
- Around line 118-121: Update the both-unpublished-export-slots-in-use branch in
DepGenCollector::run_begin to set the refusal reason to Capacity before
returning false. Preserve the existing log and return behavior.

@src/common/platform/shared/host/scope_stats_retained_runs.cpp:
- Around line 378-394: In the `terminal_banks_.opened()` path, populate
`data.device` before publishing instead of leaving its artifact header zeroed.
Keep the result of `terminal_banks_.settle` and use its reconciliation values to
set the device counters and fatal-latched state; read the per-ring capacities
from this run’s terminal header. Preserve the existing `classify_reconciled`
collection classification.

@tests/ut/cpp/common/hierarchical/test_chip_run_lane_credit_block.cpp:
- Around line 32-42: Add the standard algorithm header to the include list in
the test file so the calls to std::find and std::count have an explicit
declaration; leave the other includes and test behavior unchanged.
- Around line 223-229: In the writer thread, store to g_complete[0] before
publishing the generation change with g_generation.fetch_add, using release
ordering so the lane’s acquire read observes both preceding stores and avoids a
data race.
Review comments at @tests/ut/cpp/support/weak_link_placeholders.cpp:
- Around line 100-104: Update the weak copy_back_run_outputs_impl placeholder to

Ordinary early enqueue already lets a successor reach the device queue while its predecessor executes. Most diagnostics refused that: the host reset shared counters per run, read a "current buffer" a successor would overwrite, and the receive paths knew one run at a time. So a collecting submission waited for the run ahead of it to finish its host work. This gives the same early enqueue to runs with diagnostics on. The device still executes one operator at a time; what overlaps is a run's reconciliation and its background file work with the successor's device execution. Records and host extension sections belong to the run that produced them, through its own epoch and admitted storage. - Publish per-producer accounting into collector-owned terminal banks, reserved by run epoch. Copy and reconcile under the run's claim; keep unproved storage quarantined until producer-stop evidence permits reuse. - Initialize every terminal bank and producer slot in actual backing before exposing addresses or reservations. Use the mapped host view or checked synchronous H2D, and reject launch when initialization fails. Preserve the exact allocation and cleanup context across failed unmap/free and close retry; keep full-stride reconciliation and sparse producer semantics. - Protect ArgsDump admission, release and transport progress with the same mutex as the writer predicate. Leave the epoch mutex before notification. On processing/reference failure, log bounded mixed-time atomic cut and shard observations with the actual request identity; preserve the original deadlines, failure results, quarantine and device ownership. - Admit every requested diagnostic owner together, charge host payloads before copying, and wait for capacity outside the lane mutex against one fixed deadline. Refusal submits nothing and fails only the affected run. - Capture each native run's PMU and swimlane selection before preparation. A successor sizes its optional scheduler storage from its own immutable HostApi selection while the runner retains its active predecessor's device configuration. Registration and prewarm keep legacy fallback. - Support joined diagnostic admission on both architectures and runtimes. A5 host_build_graph refuses ArgsDump explicitly because its resident AICore scheduler provides no per-task AICPU capture boundary. Preserve the supported diagnostics and roll back upper-layer preparation state. Refuse only after validated carrier ownership, then use existing cleanup to settle the exact epoch and publish release proof. Invalid, live and recursive requests cannot overwrite storage; failed cleanup certifies nothing. A supported successor can prepare after a clean refusal. - Measure A5 host_build_graph PMU through per-subtask staging cells and settle only the graph's expected coverage after proved core retirement. Keep register restoration separate from accounting success, gated on retirement. Preserve task-matched, strictly nonzero PMU acceptance. - Attribute host graph extensions to the publishing run's admitted bucket; reject duplicate, late and unknown-run publications. Retain original argument values and task-boundary checks on the three capture backends. - Keep independent PMU init and close observations within the terminal's existing cache line. Document that endpoint enables do not prove an uninterrupted interval, absent close notes do not prove missing closes, and calculated virtual addresses do not establish physical MMIO identity. - Retain each TMR run's actual ring and tensormap capacities from its resolved cold or cached bind layout through prepared execution and its collector slot. Refuse missing required metadata before admission takes credit; delayed exports never read a successor's shared header. Preserve HBG metadata behavior, the JSON schema and device ABI. - Describe terminal identity as a post-completion stamp, not an atomic cache-line publication or a live release flag. Preserve the existing stores, barrier, flush and bank-lifetime implementation. - Deduplicate axis-checker preprocessing by its exact executed argv, resolved working directory and source identity. Group before scheduling bounded parallel work and preserve each target's coverage union, waiver rules and failure propagation. Keep results within one invocation. - Expose axis coverage, stub linkage and exporter roundtrip as separate sequential CI steps, preserving their commands, failure propagation, self-CPU environment activation. Give GitHub macOS a bounded 30-minute job ceiling; Linux and self-CPU retain 20 minutes. The persistent AICPU stream orders every successor entry after its predecessor kernel returns, including filtered threads and phase-scope destructors. The AICore stream waits for the predecessor's whole-operator event. Early host enqueue does not imply overlapping AICPU entry writers; no extra synchronization or speculative register operation is introduced. The saved compile database has 1447 covered entries and 817 exact replay keys. These count repeated work, not a measured speedup. The a4 macOS run passed Python and all 358 CTest cases but reached axis coverage after 19m45s of a 20-minute job budget. Preserve every check and concurrency setting while allowing ten additional minutes for macOS completion and variance. New-head CI must validate the full required tail. Zero-cycle PMU results remain unresolved. A matched old17129 baseline also produced zero rows; later instrumented positive runs do not prove repair or attribute the failure to this change. Strict positive-cycle, identity, numerical and cleanup assertions remain intact. No private open-gate intervention or experimental register reads enter this commit. Resource-growth waits keep the mainline plan and workspace ownership contracts alongside diagnostic-credit waits. Verified prepare rollback releases source references; ambiguous cleanup retains ownership. Native recursive-prepare refusal and backend-specific test fixtures remain intact. Prior targeted host validation passed capacity14, terminal24 and ArgsDump18 new instances. Those results belong to the previous source; the integrated source additionally passes five new targeted host cases. An original-source counterexample fails the intended layout/getter checks; the fixed cases cover real binding transitions and legacy fallback. They exercise no launched predecessor, device execution or CCE frontend. The original ArgsDump timeout and PMU failures remain separate unresolved observations. Main's APT source-refresh classification addresses a distinct installation baseline and does not guarantee recovery from persistent package payload HTTP503 failures. Seven new host cases cover refusal receipt, subsequent prepare/run, flush and close, invalid/live storage and failed-cleanup protection. They use the real C entry and CPU transport, not physical NPU execution or forked-child qualification; new-head CI must establish those paths. Part of hw-native-sys#2429
Summary
Diagnostic runs previously waited for their predecessor's host collection work
because counters, current-buffer pointers and receive paths represented one run
at a time. This change lets a successor enqueue while its predecessor's
reconciliation and background file work continue. Device operators remain serial;
records, terminal accounting and host extensions are attributed by run epoch.
Part of #2429.
Runtime behavior
Each supported owner publishes per-producer accounting into a collector-owned
terminal bank reserved by run epoch. The host copies and reconciles it under
that run's claim before reuse; storage without producer-stop proof remains
quarantined. Export storage has its own lifetime and budget.
Diagnostic admission is all-or-nothing. Capacity refusal submits nothing;
the caller waits outside the lane mutex on credit generation, against one
fixed deadline. Cleanup preserves the run's first error and reports lane
poisoning separately when both occur.
Both architectures and both runtimes answer joined-diagnostic capability from
their actual producers. A5
host_build_graphexplicitly refuses ArgsDump atthe C prepare entry before bind or diagnostic allocation. It first validates
and owns this attempt's carrier, then uses the existing cleanup path to
publish exact-epoch release proof. Only successful cleanup lets upper layers
release that invocation's inputs and keep the lane usable; invalid/live
storage, recursive preparation and failed cleanup retain their protections.
Its supported diagnostics remain available. Per-task ArgsDump on that
resident AICore-scheduler route is deferred to a separate change.
A5
host_build_graphstages PMU results per executed subtask and settlesexpected graph coverage only after proved core retirement. Register restore
depends on retirement independently of accounting success. Strict task-matched
and nonzero-cycle assertions remain enabled.
Host extension publication carries the publishing run's epoch into its
admitted bucket, charges its byte budget before copying, and rejects unknown,
duplicate or late publications. The three ArgsDump-capable backends retain
checks of each selected argument's value at its actual task boundary.
TMR ScopeStats exports keep the actual task-window, dependency-pool, heap-byte
and tensormap capacities of their own resolved bind, including cached arenas.
Immutable host metadata travels through prepared execution into the admitted
epoch slot, so delayed export cannot read a successor's shared header. Missing
required metadata refuses admission before consuming credit. HBG behavior,
retention-off behavior, JSON schema and device ABI remain unchanged.
Terminal identity is checked in a post-completion snapshot. Documentation now
states the existing stores/barrier/flush and reserved-bank lifetime contract;
sharing a cache line provides no atomic-publication guarantee. The publication
implementation and strict failed-run discard behavior are unchanged.
This is the supported scope, not a claim that every acceptance criterion passes.
Joined simulation launches, kernel mode and capture are not added by this work.
Per-run preparation configuration
A native run captures its PMU selection and swimlane level before binding.
A prepared successor therefore reserves its own optional PMU cells and scheduler
activity buffers while the runner retains its active predecessor's device
configuration. Ordinary scheduler trace cells remain unconditional. The captured
selection survives preparation waits and delayed export; registration and prewarm
without a native run retain their legacy runner-query fallback. Device execution
and diagnostic compatibility checks for joined launches are unchanged.
Terminal backing initialization
Every retained terminal allocation is initialized across all banks and the full
producer stride before its addresses or reservations become usable. Mapped
allocations use their actual host view and the existing store barrier; hostless
allocations use the platform's checked synchronous H2D callback. Initialization
failure refuses launch. Failed unmap/free retains the exact backing and cleanup
context through collectors, runners and the C API for explicit close retry.
Reconciliation still scans the full stride, accepts sparse producer identities
and reports claimed-but-unclosed records as unknown; admission and bank reuse do
not erase a live allocation.
This fixes the storage-initialization contract exposed by the prior Ubuntu A3
simulation accounting failure: 24 real producers plus inactive epoch-1 entries
28/53 contaminated the snapshot. The failing allocation's initial bytes were not
captured, so that diagnosis does not exclude every possible external writer.
It does not identify or repair the independent onboard PMU control-loss cause.
ArgsDump progress and failure evidence
Admission, slot release and transport progress update the writer generation
under the same mutex as its condition-variable check. Admission/release first
leave the epoch-state mutex, then use the existing progress helper, preserving
credit notifications and avoiding a new nested lock. This corrects a plain
counter accessed under two unrelated mutexes, also present on main.
On processing-deadline or reference-release failure, bounded host-only logs now
name the run, cut and actual control request, then sample existing atomic queue,
watermark, processed and per-shard ACK fields. The mixed-time snapshot is
explicitly diagnostic; it grants no completion or reuse permission. There are
no new device reads, normal-path probes, plain-target reads, timeout changes or
weakened quarantine decisions. Logging exceptions cannot replace the original
error.
This race has not been established as the cause of the prior A3 onboard
ArgsDump stall. That failure reached the 8000-ms processing deadline for native
run/epoch 1 and later failed a shard-reference handshake. Existing evidence
cannot distinguish unfinished drain proof from an unfinished collector callback.
Both runs' PMU controls read held72/lost0; that does not prove positive cycles
or resolve the independent earlier PMU zero-cycle failures.
Device ordering and PMU evidence
Successive joined runs belong to the same runner and use its persistent AICPU
stream. The predecessor's payload, own-AICore wait and whole-operator event
precede the successor's payload in that FIFO. The successor's AICore stream
also waits on the predecessor's whole-operator event. Thus every predecessor
entry thread returns before any successor entry setter executes, including
filtered threads and phase-scope destructors. Early host enqueue does not mean
early successor AICPU execution. The former contrary early-entry claim is
withdrawn; separate phase buffers or disjoint RunWall samples alone do not prove
writer identity. Simulation joins its producer threads before another run can
own execution. No additional host synchronization is introduced.
PMU init and close observations use separate fields in the existing terminal
cache line. Their evidence is bounded:
MMIO registers. One finalize per logical core does not prove exclusive
physical-window ownership; another logical core's restore could alias it.
CTRLand AICPU PMU MMIO are separate code interfaces; shared bit namesdo not establish hardware aliasing. HAL PMU geometry remains unverified.
A3 zero-cycle PMU results remain unresolved. The a4 CI run failed strict
HBG epoch 2 with 513 zero rows and init enabled=72/close lost=72. Local a4
measurements reproduced the same signature on a third host: one HBG epoch
had 513 zero rows while the next epoch and later same-device runs were positive.
A bounded serial control passed; its matched joined run reproduced zero counts.
Other joined runs passed, so this association neither identifies the writer nor
establishes a fix. Raw CSV counts, control readbacks and host logs were retained.
The capacity and CI-budget repairs change no PMU product behavior or assertions.
Physical MMIO identity and the source of the enable transition remain unproven.
The known same-run plain-global race is separate from cross-run FIFO ordering
and is not claimed fixed.
Axis-checker preprocessing
check_ut_cpp_axis.pygroups equivalent entries before scheduling preprocessing.Its key is the exact
preprocess_command(entry)argv, resolved working directoryand resolved
entry.file. No extra.ooperand, define or include path isstripped. Bounded parallel work evaluates each key once per invocation, and each
target still receives the union of its own entries. Case classification,
waivers, unattributed-entry errors and preprocessing failures retain their meaning.
Read-only inventory of the existing saved compile database found 1,447 covered
entries, 817 exact keys and 630 repeats across 359 covered targets. The earlier
808-key/639-repeat estimate is withdrawn because it used additional normalization
and an incomplete key. No compiler or preprocessor was run for these counts.
Six new regression cases cover sharing without mixing target coverage, distinct
cwd/defines/include paths/source identities, per-invocation lifetime and failure
propagation. They have not been run locally. All six passed in aaa041
macOS Python CI; those synthetic cases do not establish full-checker timing.
These counts are not a timing measurement. Axis coverage, stub linkage and
exporter roundtrip occupy named sequential CI steps, preserving their original
commands, self-CPU venv activation and ordinary failure propagation.
Bounded macOS CI budget
The a4 macOS job passed Python (3340 passed, 21 skipped, 108 deselected) and
all 358 CTest targets. It reached axis coverage about 19m45s into the 20-minute
job budget, was cancelled about 32 seconds into that step, and never started
stub linkage or exporter roundtrip. The annotation confirms the job-wide
20-minute limit. C++ compilation took about 11m28s; there is no evidence that
the axis checker hung. Same-head Linux completed axis in 42s and stub linkage
in 13s, which already exceeds the nominal remaining macOS allowance.
GitHub-hosted macOS now receives a 30-minute job ceiling; Linux and self-CPU
retain 20 minutes. Every command, case, required tail step, failure gate,
CTest per-case 300-second timeout and parallelism setting is unchanged.
This allows a stalled macOS job up to ten additional runner-minutes; it does
not promise a duration or improve performance. Every exact-head CI must
complete all three tail checks. A repeated timeout requires phase diagnosis,
not an automatic further increase.

Exact CTRL 0x7→0x2 values were printed only for the first reporting producer

#2614 cleanup changes are not imported.
