fix(api): preserve partial results and accurate notification counts - #2123
Preserve healthy GraphQL data when a service fails, and keep notification overview counts consistent with their lists through incremental watcher updates.
A non-null Docker root can turn a service error into data: null, discarding healthy fields from the same query. VM domain fields already preserve partial results, but the VM root also needs a nullable boundary for root-level errors.
The legacy notifier writes each new notification into both unread and archive. The archive list hides unread copies, while its counters count both. Arithmetic based only on add events also drifts when a move overwrites an existing archive copy or a removal reveals a hidden copy.
Resolution
Make the Docker and VM query roots nullable while retaining field errors. Update the published schema and affected client types.
Keep a compact per-ID index containing the unread and archive severities. Watcher add/change/unlink events reread only that ID's two possible files and apply the difference between its previous and current visible category. Moves and deletes reconcile affected IDs before returning, independently of later watcher events. No ordinary event or mutation performs a full count reconciliation.
Startup and explicit reconciliation rebuild the index from disk. Startup waits for watcher readiness and replays changes received during hydration. A failed reconciliation preserves the last valid counts and index instead of publishing a partial zeroed snapshot.
Reviewer Considerations
Ordinary count updates read at most two notification copies per affected ID, independent of archive history. Bulk operations reconcile their affected IDs.
The existing warning/alert broadcaster still reads unread notifications. Its payload updates and notification-added events remain covered separately from count updates.
The index stores IDs and severities, not notification payloads. It resets when the configured directory changes.
Notification storage, legacy file format, authorization, and persistent-notification semantics are unchanged.
Existing nullable VM domain fields retain their partial result shape, and GraphQL errors remain visible.
Behavior Changes
A failed Docker subtree no longer erases other successful root data.
Counts exclude hidden archive copies, remain stable on repeated events, and follow severity changes, removals, and overwrite moves.
Mutation responses contain reconciled counts before delayed watcher callbacks arrive.
Verification
Six targeted suites: 106 tests passed, covering GraphQL partial results, Docker/VM resolvers, authorization, and notifications.
21 notification integration cases passed with native watching and again with CHOKIDAR_USEPOLLING=true. They use real filesystem changes, Chokidar, PubSub subscribers, and GraphQL HTTP queries/mutations.
Coverage includes both legacy write orders; creation; archive/restore/delete and filtered/bulk actions; overwrite renames; severity/content changes; subscription snapshots; bursts; startup and reconciliation races; directory changes; failed moves; delayed unlink events; and read-failure recovery.
A history-size regression seeds 128 archive files and proves ordinary events perform no full recount or reads of those historical files.
The expanded tests fail against the previous implementation for event recounts, change handling, and failed reconciliation behavior.
API pnpm type-check, pnpm lint including authorization lint, and pnpm build passed.
Prior API/web code generation completed. Web type-check had the same 134 errors with candidate and baseline generated types, with no added errors. Shared UI build remains blocked by the existing unresolved @vue/language-core dependency.
Legacy duplicate-file behavior is exercised with real files. Public creation exercises the existing local-write fallback when the appliance notifier executable is unavailable. Live counter acceptance is documented below; no production deployment is claimed.
Native appliance validation
Passed on a managed, licensed Unraid 7.3.2 VM using the production-shaped PR plugin from CI run 40211461696, exact source commit fdef73bba0995652a8c29cd18cda9dd3d5bec191.
All 11 checks passed in api/scripts/qa/notification-counter.mjs: baseline; actual native dual writes at all severities; native archive; API restore; API archive over an existing copy; API archive deletion; external severity change; external unread deletion revealing the archive's original severity; native archive-only delivery; a burst of 24 native file writes; and fixture cleanup.
Each check compared cached counters against complete visible GraphQL lists and independent disk state. The run never invoked recalculateOverview. Delivery used the native script's browser-only override.
Verified the published PLG against CI (cfa341280d58b6258229965bafbbaa395695034d162f0e158cfaa1afd05bd72b), the guest's cached TXZ (b28a340ebefd98152ac634e9c78e8e058638694393470c44a572b7536d757ec7), and all 32 installed API dist files against that payload.
Actual appliance notifier SHA-256: 665fe6d4970f610172e4eb7c9e9598f1bd84544043d0021f3b7496f0babb2377.
Notification fixtures were removed, the temporary API key was deleted through the native CLI, and the provider completed cold rollback and release. The VM was not retained.
Current notification suite: 66 local tests pass, plus API type-check, lint, commit hooks, and guest-script syntax check. Exact-head CI completed successfully; dependency audit remains an advisory failure.
This proves live notification counter behavior through the native script and GraphQL. No browser or live subscription acceptance is claimed by this appliance run.
Tested 29a80c18a35deb9df2b038962f571974d6d47115 with the production-shaped plugin from CI run 40215498199 on a managed, licensed Unraid 7.4.0-rc.1 VM. CI and CodeQL passed; dependency audit is an advisory failure.
35 recorded checkpoints completed. Counters matched independent disk state and complete GraphQL lists throughout. Passed actual native API creation and metadata persistence; all three authenticated WebSocket subscriptions; unchanged-severity content updates; add-event delivery without duplicate native events; repeated native tickets; selected-ID, severity-filtered and all-item bulk archive/restore; deletion; persisted native files after service restart; and subscription reconnection.
Replaced the unread directory with a regular file before restarting the API. The public request exposed the initialization failure; after restoring the directory, public reads and mutations recovered without another process restart.
Lowered the guest's inotify watch limit, required a real logged ENOSPC from a new watched subdirectory, restored the limit, and proved that the same API process still counted real native writes. This validates the lifetime watcher error listener.
Verified the PLG (c0d47c6007aa8e2b4ec2dd021c8b0a293fe1bdc3a4923d4676e388be5d52e99b), cached TXZ (80a526aa073bd4c3c770460f5c73628c68c603e538499a01b76b759a1d75b326), and all 32 installed API dist files against the CI payload. Native notifier hash remained 665fe6d4970f610172e4eb7c9e9598f1bd84544043d0021f3b7496f0babb2377.
Local validation: 121 targeted tests pass; all 24 filesystem integration cases also pass with polling enabled. API type-check, lint, build and commit hooks pass. Regression tests reproduced watcher initialization/runtime failures before the fixes.
Cleanup verified no temporary key and no remaining isolated notification files. Original settings were restored byte-for-byte. Provider cold rollback/release completed; the guest is not retained.
Open pre-existing creation finding
The adversarial run is passed_with_findings, not a clean pass, and intentionally exited nonzero. When the installed native notifier succeeds, createNotification returns a generated UUID-based ID that differs from the actual native disk record's ID. Creation side effects, metadata, subscriptions and subsequent operations using the listed ID work; clients using the creation response's ID do not have the real record ID.
The pre-PR source at e160a4ea136e56f7bab68ce9e3b6b8cc73b3aac7 already generates this ID, passes the title to the native script, and returns the generated ID. Those operations are unchanged by this PR. This classification uses source comparison, not a baseline appliance run. The finding remains unresolved and is separate from the counter and watcher lifecycle fixes.
Final QA script diagnostics
The QA-script diagnostics commit d540c61734a6abad4cb0a72663050a74c6929e48 differs from the tested 29a80c18a only in the guest test script. API source trees are identical (14806261103820a95bd96ddffbf75b98649bb855). The script now preserves the original startup failure if restoration also fails, records restoration failure separately, and uses byte offsets when scanning logs. Targeted local checks of the actual script passed for ASCII and multibyte log prefixes and both startup/cleanup failure combinations. These diagnostic corrections were not rerun on an appliance; the full appliance evidence remains pinned to 29a80c18a above.
Burst read-cost investigation before scheduling fix
Added 12 real-filesystem/Chokidar/PubSub cost-characterization tests. They exercise 24-event bursts with empty and 1,000-unread/1,000-archive history, plus 100-event bursts with that larger history. Operations cover native-style dual-file creation, external content/severity changes, unread deletion revealing archive copies, and archive-only creation. All 12 pass with native watching and again with polling; the complete targeted set now has 133 passing tests across 8 files. API type-check and lint pass.
Measurement covers service notification-content read attempts after hydration, including warning/alert payload scans. Independent list verification occurs afterward. For 100 content/severity changes with 1,000 existing unread history files, both modes recorded 110,200 read attempts and 100 warning/alert scans. Peak simultaneous scans were 47 with native watching and 48 with polling; each local event workload took about four seconds. An archive-only burst of 100 files required 200 read attempts and zero warning scans.
Counters, final payloads, the 50-item warning limit, and notification-added uniqueness remained correct. Unrelated archive history was not reread. The tests enforce a per-event-plus-payload-scan ceiling, but they do not establish a constant per-burst budget or acceptable appliance latency. OS disk I/O, watcher metadata operations, and production hardware latency were not measured. No new QA VM acceptance is claimed. These commits change only tests and documentation; prior packaged API evidence remains applicable to the unchanged application source.
Open performance concern: unread events can launch overlapping full unread payload scans. This investigation documented amplification before the scheduling fix described below.
Warning/alert refresh scheduling fix
Warning/alert payload publication now shares one running refresh. Requests received before the scan combine after queued counter work; requests arriving during reading or publication trigger a subsequent serial refresh. There is no new timer, payload cache, schema, or file-format change. Per-ID count reconciliation and per-file notification-added delivery remain intact.
Six deterministic scheduling regressions cover simultaneous calls, a real mid-read disk change, requests during publication, requests during a failed read, and next-request recovery after read/publication failure. Before this fix, three overlap regressions failed with 101 concurrent/duplicate scans. The burst tests now require at most one active scan, at most four scans for each large-history test burst, correct final counts/payloads, and no unrelated archive payload reads.
For 100 content/severity changes with 1,000 existing unread files, native watching measured 1,300 content-read attempts and one scan, versus 110,200 and 100 scans before. Polling measured one or two sequential scans (2,400 attempts observed). These are local file-read attempts, not physical disk I/O or appliance latency measurements. Sustained events can cause further sequential scans; four scans is a test-fixture budget, not an unbounded-stream guarantee.
Validation: 139 targeted tests pass with polling, including all 42 notification scheduling/filesystem/load cases. Isolated native watcher integration and native load/scheduling tests pass. API type-check, lint/authorization lint, and production build pass. Combined local native runs intermittently miss raw Chokidar add events; the previous revision reproduces the same failure under the combined workload (131/133 pass). That local test limitation remains disclosed; it was not fixed by changing refresh scheduling.
The prior open amplification finding is addressed by this implementation and the stricter budgets. Current application source has changed: fresh CI and packaged managed-VM validation are recorded below, and the earlier appliance receipts continue to prove their pinned revisions only. The pre-existing native creation ID finding remains separate. No merge or production deployment.
Exact-head appliance validation after refresh scheduling
Validated acd1994b4ec8e48ac6f1a19dd006c5f7932cff0e using the production-shaped plugin from CI run 40232164901 on a managed, licensed Unraid 7.4.0-rc.1 VM. Main CI, including Test API, and CodeQL run 40232164782 passed. Dependency audit remains an advisory failure; release and production deployment jobs were intentionally skipped.
The same 35 adversarial checkpoints completed: native creation and dual-file delivery, counts/list/disk agreement, all three authenticated live GraphQL subscriptions, content updates at unchanged severity, no duplicate additions, bulk and filtered archive/restore/delete, service-restart persistence and reconnection, real startup-directory failure recovery without another restart, and real logged inotify ENOSPC while the same API process remained operational.
Verified the CI PLG (ec40e39f25354325bf8ba781f6c04f809fff5ca43e50c5bc32d00c2a9c777477), cached TXZ (3d5dfb3229fcd0967692c77092b4ff16470bfef3e80d6a08e22d5b8f2d07986a), and all 32 installed API dist files against that package. The installed entrypoint hash was 08844a7a9e65e3f889b67123ac6dee1631e5481c1b1efeb5cf1f716f49ac3853.
Result: passed_with_findings, intentionally exit 1. The existing native creation response ID still differs from the stored record ID. This was already present in pre-PR source; it remains a separate unresolved finding. All other recorded checkpoints passed. This run validates appliance behavior after scheduling changed; the 100-event file-read reduction remains local test evidence, not appliance disk-I/O profiling.
Cleanup verified that the temporary key was absent, isolated notification files numbered zero, the inotify limit was restored, and the original notification configuration was restored byte-for-byte. Provider cold rollback/release completed and advanced its generation. A fresh reservation listing confirmed this task's reservation was absent. The shared capacity was subsequently acquired by another job; it was left under that job's ownership. The CI waiter was verified, unloaded and cleaned up. No merge or production deployment.
Risk
Nullable roots affect generated client contracts. The notification index uses memory proportional to stored IDs; ordinary count updates avoid history scans. Read failures retain the last valid state and are reported rather than silently replacing counts with zeros.
Summary by CodeRabbit
Bug Fixes
VM and Docker queries can now return partial results when either service is unavailable, rather than requiring both query roots to be present.
Notification counts and updates stay synchronized with notification files during changes and bulk operations. Notification reads and updates can recover after watcher initialization failures.
Documentation
Added guidance for running notification-counter checks on a managed appliance, including optional extended checks and how to interpret findings.

Walkthrough
The VMs and Docker GraphQL query roots are nullable, and generated client types reflect that shape. Notification overview counts now reconcile with filesystem state and watcher events. A managed-guest script checks notification counts against GraphQL results and disk state.

Summary
Watcher events and overview reconciliation api/src/unraid-api/graph/resolvers/notifications/notifications.service.ts
The service queues watcher events during initialization and processes add, change, and unlink events. Serialized synchronization tracks unread and archived copies by ID. Overview snapshots count unread copies in preference to archived copies.
Notification operations and integration coverage api/src/unraid-api/graph/resolvers/notifications/notifications.service.ts, api/src/unraid-api/graph/resolvers/notifications/notifications.overview.spec.ts, api/src/unraid-api/graph/resolvers/notifications/notifications.service.spec.ts, api/src/unraid-api/graph/resolvers/notifications/loadNotificationsFile.test.ts
Reads and mutations wait for initialization. Deletes and moves synchronize affected IDs, and archive listing excludes IDs also present in unread. Tests cover watcher events, reconciliation, notification operations, GraphQL queries and mutations, and cleanup.
The script exercises notification operations and compares GraphQL lists and counters with disk state. It validates managed-guest inputs, writes a private report, and cleans up fixture files. The README documents guest prerequisites and acceptance evidence.
A startup watcher failure no longer requires an API restart before notification requests can recover. No remaining merge-blocking issue is established; merge after normal checks.

Explanation
The title names the two main changes: partial GraphQL results (nullable Docker and VM roots) and accurate notification counts. Both match the changeset and the linked objectives (#1837 and #1859). It is a single line in conventional-commit form and follows the title guidelines. Its scope is broad, but it reflects the primary changes and is not misleading.
Full details: Linked Issues check
Explanation
[#1837] The Docker and VM query roots are nullable. At head, docker uses @Query(() => Docker, { nullable: true }) in docker.resolver.ts. The VM query is also nullable per the raw summary of vms.resolver.ts. The schema diff from the merge base confirms Query.vms: Vms changed to Vms and Query.docker: Docker! changed to Docker. Web generated types in graphql.ts are updated to match. Partial-results tests in partial-results.spec.ts cover a failed service returning null while unrelated roots keep data, both services failing with both errors, and successful empty results. [#1859] NotificationsService keeps a per-ID index of unread and archive severities. It counts only the visible category, so archive copies hidden by an unread copy are excluded from archive.total. Watcher add, change, and unlink events reread only the affected ID's two possible files. Moves and deletes reconcile affected IDs before returning. Startup and explicit reconciliation rebuild the index, and a failed reconciliation keeps the last valid counts. The notifications overview and integration tests cover these paths, including a 128-file history regression. Source evidence for the service logic comes from the PR description and the reported test coverage. The raw diff from the previous reviewed head to head shows no changes under api/src, so the earlier service evidence still applies. The #1859 requirement is met by the described and tested behavior. Native-creation ID mismatch is not a requirement of either linked issue.
Full details: Out of Scope Changes check
Explanation
Changes map to the linked issues. [#1837] covers the nullable Docker and VM roots, the published schema in api/generated-schema.graphql, the generated web client types in web/src/composables/gql/graphql.ts, and the partial-results spec. [#1859] covers the notification service and its index, the watcher readiness and retry behavior in loadNotificationsFile.test.ts, the notification overview and service specs, and the notification-counter QA harness. The QA harness and README validate live counter behavior on a managed guest and are optional, gated tooling. They support the #1859 verification requirement and do not add product behavior. The adversarial checks cover watcher recovery, which is part of the #1859 watcher-update design. The open native-creation ID mismatch is described as pre-existing, with source comparison to the pre-PR code at e160a4e. This PR does not change that behavior, so it is not a demonstrated unrelated change. The raw diff from the previous reviewed head to head shows no api/src changes since the prior review, and the QA script diff is confined to test tooling. No ignored files limit this assessment.

Share the notification index with the shared watcher and counters
When an installed plugin fails to import, plugin.service.ts:54 constructs a separate NotificationsService before Nest creates its normal provider. The static watcher remains bound to the first instance, but each instance now has its own index and update queue while modifying the same static overview. Consequently, an archive mutation through the Nest provider and its subsequent watcher event can both apply the same delta, producing negative unread counts and doubled archive counts. Keep the index and serialization queue under the same ownership as the shared watcher and overview, or ensure these callers use one service instance.
The reason will be displayed to describe this comment to others. Learn more.
Retry initialization after an unsuccessful hydration snapshot
If any existing notification encounters a non-ENOENT read/stat failure during startup, this condition discards the entire snapshot, including all successfully read notifications. initializeNotificationsState then only logs the returned error and resolves successfully, so initializationFailed remains false and subsequent public requests never retry hydration. Even after the filesystem recovers, untouched notifications remain absent from the index and counters until an explicit recount or restart. Propagate the unsuccessful initial reconciliation into the initialization retry mechanism rather than treating it as successful initialization.
)
Custom API keys could fail mixed GraphQL queries with `Cannot read
properties of undefined (reading '0')` inside Casbin. Authentication
cleared and rebuilt the shared permission rows while another
authorization check was iterating them. This was discovered during
post-merge QA of #2123 at 3371fd4.
This uses Casbin’s existing synchronized enforcer to serialize checks
with policy mutations. Permission synchronization now removes obsolete
grants and adds missing grants, preserving unchanged grants during
repeated authentication. Permission changes still apply on the next
authentication; no permission cache, schema change or migration is
introduced.
Reviewer consideration: authorization checks now share Casbin’s
dependency-owned lock. This prevents concurrent policy mutation;
unchanged keys avoid policy writes. An in-flight check finishes before
revocation, and later checks observe the revoked permission.
Validation: all 366 authentication tests, API type-check, API lint and
authorization coverage lint passed locally. Six integration regressions
cover 48 concurrent HTTP queries with granted/denied fields, unchanged
refreshes, changed permissions, wildcard/empty permissions, a
deterministically paused authorization check overlapping policy removal,
and lock recovery after a failed check. The deterministic overlap
reproduced the exact exception before the fix. Exact-head CI build/test
and CodeQL passed; the advisory dependency audit still fails. The
packaged plugin from run 40244541250 was installed on a managed Unraid
7.4.0-rc.1 QA VM, and all 32 packaged API dist files matched the
downloaded CI payload.
Appliance QA passed 300 real HTTP requests, including 288 requests at
concurrency 24 across two distinct GUEST keys. Cases covered stable
grants and cross-key denial, actual unavailable Docker/libvirt backends
with healthy notification data retained, denied API-key mutation without
side effects, revocation and restoration on subsequent requests, empty
custom grants with an explicit GUEST role, ADMIN/VIEWER compatibility,
and persisted grants/revocations after service restart. Zero Casbin type
errors were logged. Observed p95 request latency was 49 ms (diagnostic,
not a comparative performance claim).
All five temporary keys were deleted and verified absent through the
native CLI. Notification configuration remained byte-for-byte unchanged.

Summary
Preserve healthy GraphQL data when a service fails, and keep notification overview counts consistent with their lists through incremental watcher updates.
Fixes #1837. Fixes #1859.
Why This Exists
A non-null Docker root can turn a service error into
data: null, discarding healthy fields from the same query. VM domain fields already preserve partial results, but the VM root also needs a nullable boundary for root-level errors.The legacy notifier writes each new notification into both unread and archive. The archive list hides unread copies, while its counters count both. Arithmetic based only on add events also drifts when a move overwrites an existing archive copy or a removal reveals a hidden copy.
Resolution
Make the Docker and VM query roots nullable while retaining field errors. Update the published schema and affected client types.
Keep a compact per-ID index containing the unread and archive severities. Watcher add/change/unlink events reread only that ID's two possible files and apply the difference between its previous and current visible category. Moves and deletes reconcile affected IDs before returning, independently of later watcher events. No ordinary event or mutation performs a full count reconciliation.
Startup and explicit reconciliation rebuild the index from disk. Startup waits for watcher readiness and replays changes received during hydration. A failed reconciliation preserves the last valid counts and index instead of publishing a partial zeroed snapshot.

The adversarial run is
passed_with_findings, not a clean pass, and intentionally exited nonzero. When the installed native notifier succeeds,createNotificationreturns a generated UUID-based ID that differs from the actual native disk record's ID. Creation side effects, metadata, subscriptions and subsequent operations using the listed ID work; clients using the creation response's ID do not have the real record ID.The pre-PR source at
e160a4ea136e56f7bab68ce9e3b6b8cc73b3aac7already generates this ID, passes the title to the native script, and returns the generated ID. Those operations are unchanged by this PR. This classification uses source comparison, not a baseline appliance run. The finding remains unresolved and is separate from the counter and watcher lifecycle fixes.Final QA script diagnostics
The QA-script diagnostics commit
d540c61734a6abad4cb0a72663050a74c6929e48differs from the tested29a80c18aonly in the guest test script. API source trees are identical (14806261103820a95bd96ddffbf75b98649bb855). The script now preserves the original startup failure if restoration also fails, records restoration failure separately, and uses byte offsets when scanning logs. Targeted local checks of the actual script passed for ASCII and multibyte log prefixes and both startup/cleanup failure combinations. These diagnostic corrections were not rerun on an appliance; the full appliance evidence remains pinned to29a80c18aabove.Burst read-cost investigation before scheduling fix
Added 12 real-filesystem/Chokidar/PubSub cost-characterization tests. They exercise 24-event bursts with empty and 1,000-unread/1,000-archive history, plus 100-event bursts with that larger history. Operations cover native-style dual-file creation, external content/severity changes, unread deletion revealing archive copies, and archive-only creation. All 12 pass with native watching and again with polling; the complete targeted set now has 133 passing tests across 8 files. API type-check and lint pass.
Measurement covers service notification-content read attempts after hydration, including warning/alert payload scans. Independent list verification occurs afterward. For 100 content/severity changes with 1,000 existing unread history files, both modes recorded 110,200 read attempts and 100 warning/alert scans. Peak simultaneous scans were 47 with native watching and 48 with polling; each local event workload took about four seconds. An archive-only burst of 100 files required 200 read attempts and zero warning scans.
Counters, final payloads, the 50-item warning limit, and notification-added uniqueness remained correct. Unrelated archive history was not reread. The tests enforce a per-event-plus-payload-scan ceiling, but they do not establish a constant per-burst budget or acceptable appliance latency. OS disk I/O, watcher metadata operations, and production hardware latency were not measured. No new QA VM acceptance is claimed. These commits change only tests and documentation; prior packaged API evidence remains applicable to the unchanged application source.
Open performance concern: unread events can launch overlapping full unread payload scans. This investigation documented amplification before the scheduling fix described below.
Warning/alert refresh scheduling fix
Warning/alert payload publication now shares one running refresh. Requests received before the scan combine after queued counter work; requests arriving during reading or publication trigger a subsequent serial refresh. There is no new timer, payload cache, schema, or file-format change. Per-ID count reconciliation and per-file notification-added delivery remain intact.
Six deterministic scheduling regressions cover simultaneous calls, a real mid-read disk change, requests during publication, requests during a failed read, and next-request recovery after read/publication failure. Before this fix, three overlap regressions failed with 101 concurrent/duplicate scans. The burst tests now require at most one active scan, at most four scans for each large-history test burst, correct final counts/payloads, and no unrelated archive payload reads.
For 100 content/severity changes with 1,000 existing unread files, native watching measured 1,300 content-read attempts and one scan, versus 110,200 and 100 scans before. Polling measured one or two sequential scans (2,400 attempts observed). These are local file-read attempts, not physical disk I/O or appliance latency measurements. Sustained events can cause further sequential scans; four scans is a test-fixture budget, not an unbounded-stream guarantee.
Validation: 139 targeted tests pass with polling, including all 42 notification scheduling/filesystem/load cases. Isolated native watcher integration and native load/scheduling tests pass. API type-check, lint/authorization lint, and production build pass. Combined local native runs intermittently miss raw Chokidar add events; the previous revision reproduces the same failure under the combined workload (131/133 pass). That local test limitation remains disclosed; it was not fixed by changing refresh scheduling.
The prior open amplification finding is addressed by this implementation and the stricter budgets. Current application source has changed: fresh CI and packaged managed-VM validation are recorded below, and the earlier appliance receipts continue to prove their pinned revisions only. The pre-existing native creation ID finding remains separate. No merge or production deployment.

passed_with_findings, intentionally exit 1. The existing native creation response ID still differs from the stored record ID. This was already present in pre-PR source; it remains a separate unresolved finding. All other recorded checkpoints passed. This run validates appliance behavior after scheduling changed; the 100-event file-read reduction remains local test evidence, not appliance disk-I/O profiling.Cleanup verified that the temporary key was absent, isolated notification files numbered zero, the inotify limit was restored, and the original notification configuration was restored byte-for-byte. Provider cold rollback/release completed and advanced its generation. A fresh reservation listing confirmed this task's reservation was absent. The shared capacity was subsequently acquired by another job; it was left under that job's ownership. The CI waiter was verified, unloaded and cleaned up. No merge or production deployment.
Risk
Nullable roots affect generated client contracts. The notification index uses memory proportional to stored IDs; ordinary count updates avoid history scans. Read failures retain the last valid state and are reported rather than silently replacing counts with zeros.
