kind: reduce smoke latency across 14 shards - #1741
Reduce typed Kind smoke latency while keeping all 14 CI shards. Replace artificial waits with observed state or explicit release, consolidate duplicate scenarios, and avoid unused VM fixtures. Real lease, eviction, and garbage-collection safety windows remain.
CI installs independent tools concurrently and uses a lighter observability layout: backend images and pods are confined to the infra node, Grafana is omitted, and all collectors and telemetry scenarios remain. Network denial probes and their paired positive controls use a two-second per-attempt bound. Updated scheduling hints distribute the same inventory across fourteen shards.
Network denial checks pair guest observations with unrestricted controls and prove policy readiness. The raw ECW internet-deny case is now explicitly Kind-only because a policy with no allowed egress needs a node-side readiness observation. Leader refusal qualifies its own shortened budget using a concurrent unreachable controller. Streamed writes use distinct replacement bytes; encrypted restore requires natural pod retirement; protected orphan pods remain observed for two GC intervals after the positive control is reaped.
The additive space-tmplmgr get --manifest flag reads a committed cached manifest for an exact digest. It rejects responses that do not acknowledge cached-only lookup. The mode avoids pull/reconciliation, but the existing RPC still refreshes LRU access and may initialize missing settings; polling ends during fixture preparation, before eviction observation. The inline release-file hook is inactive without test features, renews claims while held, and retains a bounded deadline. Missing ownership fails release immediately.
Scenario tiers make selection explicit: PR CI runs routine scenarios, Main runs routine plus main, and manual scenarios require special prerequisites or a deferred-contract reason and run by name. The 19 manual declarations use explicit metadata; nine duplicate diagnostic registrations are removed. External scenario packages must migrate ignored="reason" to tier="manual", manual_reason="reason". Template and environment restrictions and quarantine still apply. The generated current scenario index reports the registered claims and capabilities. Python CI runs python -m space_smoke.inventory --check before its tests, so stale generated documentation fails validation.
Upload-admission 429 and retention claim/finish-forward checks run on Main. Node-selector extras run on Main and in PR CI for changes to placement, capacity admission, shared pod rendering or related deployment configuration. These moves preserve the scenarios but delay detection for other PRs until Main. Rate-limiters and slow-operation fairness stay routine. Fail-open now requires HTTP 201 and a sandbox identity from every create while Redis is unavailable; server errors no longer count as evidence. Zero-vCPU rejection shares command validation's positive create control and owned cleanup on both supported substrates.
local.deferred_btrfs_send_capture_restores_cross_node: remote restore, preserved state and working data plane; the codec-independent diagnostic entry point is removed
Explicit tenant-allow precedence in the policy table; live-node limitation below
Identity and explicit deletion/absence are owned by ecw.command_round_trip; streaming loopback owns authenticated loopback-only reachability; refresh/timeout rearm use independent sandboxes in ecw.refresh_keepalive. Deferred capture retains the cross-node restore assertions. The removed diagnostic registrations offered no additional routine coverage.
The routine inventory also combines cold eviction, snapshot reaping, and template LRU checks using distinct owned fixtures whose eligibility clocks run together; all original durability, protection, cleanup, and guest assertions remain. The three GC preparation/completion helpers live in their sole routine owner; their bodies are unchanged apart from private identifier names. Inline queued suspend/wake ordering now shares the failover/load scenario's setup, with ordering established before inline permits are occupied.
Teardown restart reads the production CLI after startup recovery instead of holding a fixed observation window. Both leader-election scenarios change their budget inside the owned mutation scope and restore the standing settings before other scenarios run. Every shard starts with the ordinary chart settings. Duration hints use comparable-run medians where available; old scenario behavior and the former preset shard are excluded from those samples. Teardown retains the production transfer retry schedule and its 600-second restore bound; a slow replacement can still incur the 120-second retry interval.
Worker Python dependencies have their own reusable cache stage. PRs only import remote caches; trusted main publishes them. Ordinary seed identity and final image provenance remain per-run.
Retain credential-authority ownership, public/admin Service isolation, HPA ownership of replica counts, upload-admission memory safety, and executed-shim/rendered-workload consistency across datadog/otel/off. Ancillary installer retry/race and shell fixture checks use controlled time, synchronization, and smaller inputs.
Individual coverage reductions
File or scenario
Reduction, reason, and remaining evidence
ecw.loopback_route_stays_open
Reduce the minimum stream observation from eight to five seconds. The regression closes the bridge after three seconds; the retained streamed read crosses that boundary and rejects premature closure. This does not claim eight-second uptime coverage.
ecw.pause_connect_race
Default cycles decrease from ten to three: initial restore plus repeated reuse of the same sandbox. This intentionally reduces probabilistic stress sampling, not the assertions in each cycle. SPACE_SMOKE_PAUSE_CONNECT_ITERATIONS=10 restores the previous stress count; values up to 100 remain available.
space_smoke/tests/test_framework.py
Remove the manually duplicated scenario inventory and redundant ID-set check. Automatic discovery, duplicate-registration rejection and all-shard completeness remain behaviorally checked; adding a legitimate scenario should not require updating another catalog. Invalid sandbox counts, including counts ignored by a sandbox-free KindAdmin, are rejected. The sharding algorithm is checked with independent synthetic heavy/light cases; whether the current inventory balances better is measured in CI instead of asserted against changing duration hints.
test_network_policy_suite_scenarios.py
Remove fixture-call/phase-name/URL transcripts; they executed neither policy evaluation nor network traffic. Live deny-precedence and suspend/restore scenarios still probe reachable and blocked destinations, with positive controls.
test_kind_control_plane_ha.py
Keep public Services excluding admin-only pods and HPA targets omitting explicit replica counts. Remove fixed migration container names/order, the ban on every API init container, exact port/replica/HPA-metric inventories and rollout percentages. Real entry traffic and leader-election fault scenarios establish reachability and HA behavior; they do not assert every deployment default.
test_kind_ingress_activation.py
Remove exact endpoint/port/Secret/path/fsGroup/RBAC dictionaries and TLS-script text parsing. Successful cold wakes exercise deployed connectivity, and Rust auth tests cover supplied-policy decisions. These do not replace a deployed negative authorization test; that test-coverage limitation is stated below.
test_kind_data_plane_native_files.py
Keep drain-budget acceptance/refusal, disabled-mode drain validation, and memory budgets with admission explicitly enabled. Remove the literal default drain duration, exact endpoint/account/network-policy lists and caller-chart mode defaults. Native file, wake, idempotency and namespace-isolation smokes exercise supported behavior; they do not freeze every disabled-mode deployment setting.
test_kind_known_egress_chart.py
Remove empty/default/null/pass-through list assertions; retain rejection of malformed maps and non-string domain lists. Known-egress parsing and gateway policy have owning Rust tests. Custom Helm lists reaching a live gateway are not separately qualified.
test_kind_node_service_env.py
Remove the repeated default-absent upload-budget assertion. Keep credential confinement across services/roles, credential-authority ownership, zero preservation and non-exponent numeric serialization.
test_kind_telemetry_config.py
Remove fixed receiver/tag/protocol/default ladders and per-role/init-container pass-through matrices. Keep the six-case executed-shim/rendered-workload identity and exporter contract, guest-output exclusion, invalid endpoint/configuration refusal, watched-file precedence and backend installation table (including its default row). OTLP delivery smoke does not claim Datadog/off runtime delivery coverage. Removed endpoint literals are generic local Collector Service DNS documented in the public chart defaults.
test_kind_datadog_backend.py
Remove a literal selector-substring assertion whose stub returned the same pods regardless of the selector. Keep rendered/running Agent ownership checks, verifier refusal cases, SaaS consent, local stop intent and rollback. Actual Kubernetes selector evaluation is not mocked into existence.
test_kind_host_paths.py
Remove byte-for-byte preservation of generated comments; retain path/mount/symlink/ownership validation, checksum failures, atomic publication and the real installer lock race. Virtual retry time and the explicit race handshake preserve those behavioral assertions.
test_kind_observability_helpers.py
Remove the source-string check that every helper mentions lib/release.sh. Tests still execute every helper's cluster/namespace/ownership refusal and data-loss-consent paths, plus unchanged/drifted release reconciliation.
test_kind_prune_superseded_images.py
Remove regex inventories of Tilt image declarations and Dockerfile title-label text. Keep current/in-use/foreign/previous images protected, fail-closed reads, dry run, retries and concurrent-build races. Future image-list/title omissions can still leave unpruned disk usage; inventory completeness is now a configuration-review responsibility.
test_kind_registry_cache.py
Replace the full expected Docker argument transcript with import/export authorization: PRs import only, trusted main exports dependencies, final artifacts never export, invalid callers fail before Docker, and actual build failures propagate. Exact scope spelling, argument order and unrelated flags are not frozen.
Validation
Rebased head 3465fbfd53a2 is one commit atop remote/main at 2ea3aad36140. Conflict resolution preserves main's Python 3.14 guest-update packaging and adapts its two new dedicated-node scenarios to the manual tier; the generated index includes both. After rebase, 683 smoke harness checks passed, with one e2fsprogs-dependent skip on macOS; Ruff, shell syntax, index freshness and Gitleaks passed. CI on this rebased head is pending. The measurements below belong to the explicitly named earlier revisions.
Before rebase, ab30d7d5c695: 683 existing smoke harness checks passed locally, with one e2fsprogs-dependent check skipped on macOS. The generated-index validator accepted current content and rejected a disposable stale copy. An AST comparison confirmed the three relocated GC helper bodies are identical after identifier renaming. Existing identity, deletion, timeout, loopback and cross-node safety checks now exercise their routine owners. Ruff, shell syntax and index freshness passed. No routine steps or assertions changed in this cleanup: the placement-selected PR inventory remains 118 executions across fourteen shards. Pull CI passed on this head, including all fourteen Kind shards; Direct CI also passed. Removing already-manual wrappers makes no additional runtime-saving claim.
Before diagnostic cleanup, 6d2df35979da: 687 existing smoke-harness checks passed locally; one check requiring e2fsprogs skipped on macOS. Existing fail-open coverage failed before the assertion fix and passed afterward. A disposable runner simulation proved exact-once coverage across fourteen shards for routine (117 executions), placement-related PR (118) and Main (120) selections. Invalid tiers and named inclusions fail before bootstrap; manual cases cannot enter implicit runs. All 36 real placement-path selection cases, including draft deferral and opt-in, passed. Ruff, workflow YAML and generated-index validation passed. Pre-cleanup Pull CI passed on the first attempt: all fourteen Kind shards passed all 118 selected executions (114 unique scenarios), without timing-parser warnings. Redis-outage probes returned four HTTP 201 responses. Folded zero-vCPU validation returned HTTP 400 invalid_request, retryable=false, with neither an operation nor a sandbox ID. The placement-selected node-selector case passed. All three had clean cleanup. Upload admission and retention were intentionally excluded from this PR run, not counted as passes; Main's 120-execution selection was verified locally. Pre-cleanup Direct CI also passed.
On the preceding revision 8b3a29fa7801, Pull CI is green after a failed-job rerun. All fourteen Kind shards passed all 121 selected executions, and Python checks passed on the first attempt. The first attempt failed the unchanged Rust quota-lock test with a 50 ms statement timeout; the failed Rust job passed on rerun without source changes. The exact timed-out statement was not logged, so this is not claimed as a diagnosed infrastructure failure. Direct validation also passed.
The mount-membership guard now consumes its input fully: early grep -q exit could make the producer fail with SIGPIPE under pipefail and skip a matching mount. A disposable reproduction changes from status 141 to success; 77 existing Linux host-path checks passed with six intentional root-permission skips. The four-node diagnostic assertion remains unchanged and passed final Python CI. The exact short-input failure from the preceding CI run was not reproduced locally.
The profile removal also passed 57 existing framework/sharding/leader-election checks, Ruff, workflow YAML and Tiltfile parsing.
The prior revision passed all 121 selected executions on fourteen shards at f9829c7a71c7; Direct passed all 70. That revision's refusal shard used shortened controller settings for its unrelated scenarios too. Those passes therefore do not qualify that shard's other scenarios at ordinary settings. The current revision removes the startup preset, planner-only CLI path and no-restore bypass; both election scenarios use their scoped override/restoration. All fourteen shards remain available for balancing.
Existing focused framework, sharding, leader-election, GC, teardown, inline, native HTTP/deadline, and image-cache checks passed. Shell/YAML/Tiltfile syntax, Ruff, Helm rendering and seed-lock validation passed. Existing Rust inline-deadline, network-precedence, claim-renewal and held-node regressions passed; affected-crate Clippy and formatting passed. Disposable mutations showed that a no-op streamed write, tenant allow ahead of IMDS protection, disabled upload admission, exposed admin pods and explicit HPA-owned replicas are rejected.
Measured impact
Latest measured pre-rebase head ab30d7d5c695 measured 3,083 seconds aggregate typed work, 221 seconds median typed shard and 242 seconds maximum typed shard. Median whole job duration was 570.5 seconds (9m31s rounded); the longest individual job was 612 seconds (10m12s). First shard start to last completion was 680 seconds (11m20s). The last-finishing shard started 68 seconds after the first; its path was 384 seconds before typed execution, 226 seconds typed, and 2 seconds afterward. Median explicit producer wait was 4 seconds, versus 85 seconds in the preceding run. These differences show substantial run-to-run variation, not a controlled causal estimate of the final wrapper cleanup, which does not change the routine workload.
Pre-cleanup tier comparison with the immediately preceding pre-tier baseline uses fourteen shards in both runs:

Aggregate typed work decreased 166 seconds (5.0%), but this run did not improve critical-path latency. Shard 8 took 285 seconds; its stopped-restart scenario took 101.9 seconds versus 56.9 seconds previously. Its two stop/start cycles stayed approximately 11.1 seconds each, while the final observed node cleanup took 77.0 seconds versus 31.9 seconds. That scenario was unchanged by the tier revision. The next-longest typed shard took 237 seconds. Setup/producer delays and the cleanup tail both affect the observed 12m52s completion span; this single comparison does not establish a causal wall-time saving. Keep comparable-run medians rather than replacing duration hints with this one tail sample.
The pre-tier baseline 8b3a29fa7801, with ordinary shard startup settings, measured 121 executions: 3,344 seconds aggregate typed time, 259 seconds slowest typed shard, and 240.5 seconds median typed shard. Median whole Kind job time was 653.5 seconds; first Kind start to last completion was 675 seconds (11m15s). Against the prior PR baseline below, aggregate typed time fell 194 seconds (5.5%) and the slowest typed shard fell 12 seconds (4.4%). Against the parent, the reductions were 841 seconds (20.1%) and 64 seconds (19.8%). These are observed run differences, not controlled estimates of each change's causal contribution.
Before removing the preset, the measured revision reduced aggregate typed work by 408 seconds (11.5%) and the slowest typed shard by 28 seconds (10.3%) against the prior PR baseline. Against the parent, those reductions are 1,055 seconds (25.2%) and 80 seconds (24.8%). That assignment also cut the measured experiment's slowest typed step from 278 to 243 seconds; individual-case runtime variance contributes alongside balancing.
Against the prior PR baseline, the three GC cases total 297.3→138.0 seconds combined, teardown 171.7→53.6 seconds, the inline pair 100.6→61.6 seconds combined, and refusal 161.8→141.2 seconds. The preceding passing experiment independently measured 138.2, 52.6, 65.1 and 136.7 seconds respectively. These case savings are not additive wall-time savings across fourteen shards. An earlier failed experiment is excluded from the passing comparisons; the current implementation removes the startup preset entirely. Refusal returns to its normal setup/restoration, so its shortened-preset timing is not a retained saving.
All fourteen experiment publisher builds reused the early export. Compression overlapped readiness on 10/14 shards (median 4.0 seconds); the final seed freshness check still waited on the lock on 12/14 (median 8.3 seconds). Publisher-resource median fell 29.75→21.2 seconds against the earlier baseline. Runner speed and upstream readiness also varied, so the full resource difference is not a causal wall-time estimate. Earlier paired runs measured tool-install medians 16.5→13 seconds and observability 98.5→60 seconds; all collectors remain.
Whole-job median latency is effectively unchanged against the prior PR baseline. In the earlier pre-removal run, non-typed time was a median 422.5 seconds per shard. That run’s step medians included 83 seconds waiting for the producer, 153.5 seconds in baseline bring-up, 62.5 seconds creating Kind and 58 seconds installing observability. These medians are not an additive critical-path model. Completion spans include producer waits, cache warmth, host variance and staggered starts; the 243-second typed maximum is not the full PR gate's duration.
The worker dependency stage measured 10.773 seconds cold and 0.447 seconds warm locally on ARM64. This is not a full-worker x86 CI saving; the new remote cache scope remains cold until trusted main publishes it.
Severity and risk
Severity does not apply: test cost and diagnostic-quality improvement. The risks are weakened coverage during consolidation and flakes from shorter observation windows. Independent controls, distinct assertions, and real safety windows address those risks; shorter negative probes still have the limits of bounded observations. The CI observability layout is for fresh clusters and does not migrate existing node-bound volumes; ordinary local development retains the full layout. Cleanup failure remains a test failure, with HTTP error bodies retained. SQL and protobuf contracts are unchanged. Revert this PR to restore the previous inventory and behavior.
Not covered
The canonical known gaps describe live IMDS precedence through the installed gateway/nft path, deployed negative ingress authorization, and browser console scenarios withheld by CI. Unit decisions, rendering snapshots and positive traffic do not establish those missing runtime checks. No bypass was demonstrated. The tier moves above change validation cadence; they do not establish equivalent PR coverage.
AI assistance: Codex drafted the implementation, tests, and this description.
This pull request updates smoke framework contracts, scenario selection, and Kind fixture types. It adds release-file controlled inline holds, new admin and network-aware fixtures, and revised leader-election, network-policy, drain, and recovery helpers. It also retags, removes, and rewires smoke scenarios and tests. CI and supporting scripts now use smoke tiers, observability layouts, placement selection, and revised build and cache behavior.

Merge Risk: High · up to 3465f
This change shortens smoke-test time by consolidating and removing scenarios and by moving some checks out of pull-request CI. Some coverage that previously ran on every PR now runs only on Main or by name, and some assertions were removed. Confirm that the consolidated scenarios still catch the regressions the removed ones did before merging.
Security architecture risk: Low · up to 3465f
The reviewed changes preserve existing request authorization and operation-ownership controls. No introduced security concern was verified. Risk is low rather than minimal because review coverage is incomplete and some recovery interleavings remain unverified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The release signal is API-instance configuration rather than a per-tenant request parameter: held operations on an instance can share the configured file. Its effective control therefore belongs to the environment and filesystem authority of that test-enabled instance, not to a newly exposed tenant endpoint.
Trust Boundaries and Controls
observed — The existing template-manager server invokes peer authorization before cached-only handling and rejects cached-only requests lacking an exact digest or carrying caller_org_id. Separately, inline hold and release-file environment values are read through a feature-gated helper that returns no override without test hooks.
Resilience and Maintainability Implications
observed — The release wait retains a bounded deadline; missing or unreadable release files do not end it early. Manifest polling is a synchronous, bounded registration-preparation step, with an outer command timeout, rather than a background reader that continues refreshing cache recency after the method returns.

Duplicate-ID assertion cannot fail.
REGISTRY stores scenarios in a dict keyed by ID, so IDs are unique by construction. ScenarioRegistry.register already raises on duplicates. Iteration is already sorted. Because of this, assertEqual(ids, sorted(set(ids))) always passes and detects no regression. The comment says it rejects duplicate identities, but the duplicate case is covered by test_registry_rejects_duplicate_ids. Delete these lines.
As per path instructions: "Flag assertions that cannot fail".
Proposed fix
- # Discovery must be deterministic and reject duplicate identities; the- # fixture below proves decorators register executable scenarios. The- # full product inventory is deliberately not mirrored here.- ids = [scenario.id for scenario in REGISTRY]- self.assertEqual(ids, sorted(set(ids)))

The sleep stub rounds fractional arguments up by one, which can inflate the fixture clock.
For sleep 0.5, ${1%.*} gives 0, and the stub adds 1 second. For sleep 5.0, it gives 6 seconds instead of 5. Elapsed-time bounds still hold because the clock only runs fast. But a bound that asserts a minimum wait would pass wrongly. Current callers use integer values, so the impact is low. Round up only when the fraction is nonzero.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
A test was removed without a replacement.
The deleted test asserted that every release's local.sh references lib/release.sh. If that is a contract the Kind harness relies on, nothing now covers it. If the check was a source-inspection change detector, the removal is justified. Please state which in the PR description.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
load_pinned_images returns 1 and aborts the install when the CI infra node is missing from the Kind cluster.
The function runs before kind get nodes output is validated. If kind get nodes returns nothing, for example because of a transient failure whose stderr is hidden by 2>/dev/null, the ci check fails with a misleading "does not belong" message. The doc comment says the function "Never fails the install", and this new return 1 contradicts it. set -e is presumably active. The caller at Line 160 does not guard the call, so the whole bring-up exits.
Fix: keep the check, but update the function comment so it states that the ci layout can fail. The infra-node check at Lines 151-157 already validates the node through kubectl, so this second check is mostly redundant.

Type probe_timeout_seconds and timeout_seconds as int only if callers never pass fractions, or else accept float.
_probe_https formats the value directly into curl -m {timeout_seconds}. curl accepts fractional seconds, and the DNS probe path does the same through float(timeout_seconds). The int annotation is stricter than the behavior. A caller that passes 0.5 fails type checks, though the code would work.
Annotate these parameters as float. Keep the nonpositive check.

Replace fixed waits with observed state or explicit release, overlap independent GC eligibility windows, and share inline setup while preserving ordering, live-claim and exactly-once assertions. Keep real safety windows and all fourteen shards. Election scenarios restore their scoped settings; no shard starts with an unrelated scenario's shortened budget.
Declare routine, main and manual tiers instead of overloading empty template sets or ignored flags. Main runs routine plus main; PRs run routine and re-include the node-selector check for placement changes. Upload admission, retention and node-selector extras retain deployed coverage on Main. Manual cases require special prerequisites or a deferred contract and remain runnable by name. Remove nine duplicate diagnostic registrations; routine scenarios retain their assertions, and GC helpers live with their sole routine owner. Generate the current scenario index from declarations, enforce freshness in Python CI, and keep current coverage gaps in one place. Extension packages must migrate ignored declarations to the manual tier.
Require successful sandbox admission from every Redis-outage probe. Fold zero-vCPU rejection into portable command validation with its positive control and owned cleanup. Bound controlled negative network probes, parallelize tools, slim CI observability while retaining collectors, and cache worker dependency stages. Keep the feature-gated inline release hook and exact cached-manifest CLI mode; cached lookup intentionally touches LRU. Consume the mount-membership pipeline fully to avoid early-reader SIGPIPE under pipefail. SQL, protobuf and production runtime defaults are unchanged.
Validation after rebase onto main 2ea3aad: 683 smoke harness checks passed, with one e2fsprogs-dependent check skipped on macOS. Ruff, shell syntax, generated-index freshness and the Gitleaks hook passed. Preserve main's Python 3.14 guest-bundle packaging and migrate its two new dedicated-node scenarios to the manual tier. The previous head ab30d7d passed Pull CI on all fourteen Kind shards and Direct CI; CI must qualify the rebased head separately. Existing affected Rust checks passed before rebase. Browser, live IMDS precedence and negative ingress-authorization gaps remain documented. Revert to restore the previous harness and inventory.

Summary
Reduce typed Kind smoke latency while keeping all 14 CI shards. Replace artificial waits with observed state or explicit release, consolidate duplicate scenarios, and avoid unused VM fixtures. Real lease, eviction, and garbage-collection safety windows remain.
CI installs independent tools concurrently and uses a lighter observability layout: backend images and pods are confined to the infra node, Grafana is omitted, and all collectors and telemetry scenarios remain. Network denial probes and their paired positive controls use a two-second per-attempt bound. Updated scheduling hints distribute the same inventory across fourteen shards.
Network denial checks pair guest observations with unrestricted controls and prove policy readiness. The raw ECW internet-deny case is now explicitly Kind-only because a policy with no allowed egress needs a node-side readiness observation. Leader refusal qualifies its own shortened budget using a concurrent unreachable controller. Streamed writes use distinct replacement bytes; encrypted restore requires natural pod retirement; protected orphan pods remain observed for two GC intervals after the positive control is reaped.
The additive
space-tmplmgr get --manifestflag reads a committed cached manifest for an exact digest. It rejects responses that do not acknowledge cached-only lookup. The mode avoids pull/reconciliation, but the existing RPC still refreshes LRU access and may initialize missing settings; polling ends during fixture preparation, before eviction observation. The inline release-file hook is inactive without test features, renews claims while held, and retains a bounded deadline. Missing ownership fails release immediately.Scenario tiers make selection explicit: PR CI runs routine scenarios, Main runs routine plus main, and manual scenarios require special prerequisites or a deferred-contract reason and run by name. The 19 manual declarations use explicit metadata; nine duplicate diagnostic registrations are removed. External scenario packages must migrate
ignored="reason"totier="manual", manual_reason="reason". Template and environment restrictions and quarantine still apply. The generated current scenario index reports the registered claims and capabilities. Python CI runspython -m space_smoke.inventory --checkbefore its tests, so stale generated documentation fails validation.Upload-admission 429 and retention claim/finish-forward checks run on Main. Node-selector extras run on Main and in PR CI for changes to placement, capacity admission, shared pod rendering or related deployment configuration. These moves preserve the scenarios but delay detection for other PRs until Main. Rate-limiters and slow-operation fairness stay routine. Fail-open now requires HTTP 201 and a sandbox identity from every create while Redis is unavailable; server errors no longer count as evidence. Zero-vCPU rejection shares command validation's positive create control and owned cleanup on both supported substrates.

Deferred capture retains the cross-node restore assertions. The removed diagnostic registrations offered no additional routine coverage.The routine inventory also combines cold eviction, snapshot reaping, and template LRU checks using distinct owned fixtures whose eligibility clocks run together; all original durability, protection, cleanup, and guest assertions remain. The three GC preparation/completion helpers live in their sole routine owner; their bodies are unchanged apart from private identifier names. Inline queued suspend/wake ordering now shares the failover/load scenario's setup, with ordering established before inline permits are occupied.
Teardown restart reads the production CLI after startup recovery instead of holding a fixed observation window. Both leader-election scenarios change their budget inside the owned mutation scope and restore the standing settings before other scenarios run. Every shard starts with the ordinary chart settings. Duration hints use comparable-run medians where available; old scenario behavior and the former preset shard are excluded from those samples. Teardown retains the production transfer retry schedule and its 600-second restore bound; a slow replacement can still incur the 120-second retry interval.
Worker Python dependencies have their own reusable cache stage. PRs only import remote caches; trusted main publishes them. Ordinary seed identity and final image provenance remain per-run.
Retain credential-authority ownership, public/admin Service isolation, HPA ownership of replica counts, upload-admission memory safety, and executed-shim/rendered-workload consistency across datadog/otel/off. Ancillary installer retry/race and shell fixture checks use controlled time, synchronization, and smaller inputs.

Rebased head
3465fbfd53a2is one commit atopremote/mainat2ea3aad36140. Conflict resolution preserves main's Python 3.14 guest-update packaging and adapts its two new dedicated-node scenarios to the manual tier; the generated index includes both. After rebase, 683 smoke harness checks passed, with one e2fsprogs-dependent skip on macOS; Ruff, shell syntax, index freshness and Gitleaks passed. CI on this rebased head is pending. The measurements below belong to the explicitly named earlier revisions.Before rebase,
ab30d7d5c695: 683 existing smoke harness checks passed locally, with one e2fsprogs-dependent check skipped on macOS. The generated-index validator accepted current content and rejected a disposable stale copy. An AST comparison confirmed the three relocated GC helper bodies are identical after identifier renaming. Existing identity, deletion, timeout, loopback and cross-node safety checks now exercise their routine owners. Ruff, shell syntax and index freshness passed. No routine steps or assertions changed in this cleanup: the placement-selected PR inventory remains 118 executions across fourteen shards. Pull CI passed on this head, including all fourteen Kind shards; Direct CI also passed. Removing already-manual wrappers makes no additional runtime-saving claim.Before diagnostic cleanup,
6d2df35979da: 687 existing smoke-harness checks passed locally; one check requiring e2fsprogs skipped on macOS. Existing fail-open coverage failed before the assertion fix and passed afterward. A disposable runner simulation proved exact-once coverage across fourteen shards for routine (117 executions), placement-related PR (118) and Main (120) selections. Invalid tiers and named inclusions fail before bootstrap; manual cases cannot enter implicit runs. All 36 real placement-path selection cases, including draft deferral and opt-in, passed. Ruff, workflow YAML and generated-index validation passed. Pre-cleanup Pull CI passed on the first attempt: all fourteen Kind shards passed all 118 selected executions (114 unique scenarios), without timing-parser warnings. Redis-outage probes returned four HTTP 201 responses. Folded zero-vCPU validation returned HTTP 400invalid_request,retryable=false, with neither an operation nor a sandbox ID. The placement-selected node-selector case passed. All three had clean cleanup. Upload admission and retention were intentionally excluded from this PR run, not counted as passes; Main's 120-execution selection was verified locally. Pre-cleanup Direct CI also passed.On the preceding revision
8b3a29fa7801, Pull CI is green after a failed-job rerun. All fourteen Kind shards passed all 121 selected executions, and Python checks passed on the first attempt. The first attempt failed the unchanged Rust quota-lock test with a 50 ms statement timeout; the failed Rust job passed on rerun without source changes. The exact timed-out statement was not logged, so this is not claimed as a diagnosed infrastructure failure. Direct validation also passed.The mount-membership guard now consumes its input fully: early
grep -qexit could make the producer fail with SIGPIPE underpipefailand skip a matching mount. A disposable reproduction changes from status 141 to success; 77 existing Linux host-path checks passed with six intentional root-permission skips. The four-node diagnostic assertion remains unchanged and passed final Python CI. The exact short-input failure from the preceding CI run was not reproduced locally.The profile removal also passed 57 existing framework/sharding/leader-election checks, Ruff, workflow YAML and Tiltfile parsing.
The prior revision passed all 121 selected executions on fourteen shards at
f9829c7a71c7; Direct passed all 70. That revision's refusal shard used shortened controller settings for its unrelated scenarios too. Those passes therefore do not qualify that shard's other scenarios at ordinary settings. The current revision removes the startup preset, planner-only CLI path and no-restore bypass; both election scenarios use their scoped override/restoration. All fourteen shards remain available for balancing.Existing focused framework, sharding, leader-election, GC, teardown, inline, native HTTP/deadline, and image-cache checks passed. Shell/YAML/Tiltfile syntax, Ruff, Helm rendering and seed-lock validation passed. Existing Rust inline-deadline, network-precedence, claim-renewal and held-node regressions passed; affected-crate Clippy and formatting passed. Disposable mutations showed that a no-op streamed write, tenant allow ahead of IMDS protection, disabled upload admission, exposed admin pods and explicit HPA-owned replicas are rejected.
Measured impact
Latest measured pre-rebase head
ab30d7d5c695measured 3,083 seconds aggregate typed work, 221 seconds median typed shard and 242 seconds maximum typed shard. Median whole job duration was 570.5 seconds (9m31s rounded); the longest individual job was 612 seconds (10m12s). First shard start to last completion was 680 seconds (11m20s). The last-finishing shard started 68 seconds after the first; its path was 384 seconds before typed execution, 226 seconds typed, and 2 seconds afterward. Median explicit producer wait was 4 seconds, versus 85 seconds in the preceding run. These differences show substantial run-to-run variation, not a controlled causal estimate of the final wrapper cleanup, which does not change the routine workload.Pre-cleanup tier comparison with the immediately preceding pre-tier baseline uses fourteen shards in both runs:
6d2df35979daAggregate typed work decreased 166 seconds (5.0%), but this run did not improve critical-path latency. Shard 8 took 285 seconds; its stopped-restart scenario took 101.9 seconds versus 56.9 seconds previously. Its two stop/start cycles stayed approximately 11.1 seconds each, while the final observed node cleanup took 77.0 seconds versus 31.9 seconds. That scenario was unchanged by the tier revision. The next-longest typed shard took 237 seconds. Setup/producer delays and the cleanup tail both affect the observed 12m52s completion span; this single comparison does not establish a causal wall-time saving. Keep comparable-run medians rather than replacing duration hints with this one tail sample.
The pre-tier baseline
8b3a29fa7801, with ordinary shard startup settings, measured 121 executions: 3,344 seconds aggregate typed time, 259 seconds slowest typed shard, and 240.5 seconds median typed shard. Median whole Kind job time was 653.5 seconds; first Kind start to last completion was 675 seconds (11m15s). Against the prior PR baseline below, aggregate typed time fell 194 seconds (5.5%) and the slowest typed shard fell 12 seconds (4.4%). Against the parent, the reductions were 841 seconds (20.1%) and 64 seconds (19.8%). These are observed run differences, not controlled estimates of each change's causal contribution.All columns use fourteen shards. Sources: parent, prior PR baseline, experiment, and before profile removal. The comparison runs use the same main-branch base.
Before removing the preset, the measured revision reduced aggregate typed work by 408 seconds (11.5%) and the slowest typed shard by 28 seconds (10.3%) against the prior PR baseline. Against the parent, those reductions are 1,055 seconds (25.2%) and 80 seconds (24.8%). That assignment also cut the measured experiment's slowest typed step from 278 to 243 seconds; individual-case runtime variance contributes alongside balancing.
Against the prior PR baseline, the three GC cases total 297.3→138.0 seconds combined, teardown 171.7→53.6 seconds, the inline pair 100.6→61.6 seconds combined, and refusal 161.8→141.2 seconds. The preceding passing experiment independently measured 138.2, 52.6, 65.1 and 136.7 seconds respectively. These case savings are not additive wall-time savings across fourteen shards. An earlier failed experiment is excluded from the passing comparisons; the current implementation removes the startup preset entirely. Refusal returns to its normal setup/restoration, so its shortened-preset timing is not a retained saving.
All fourteen experiment publisher builds reused the early export. Compression overlapped readiness on 10/14 shards (median 4.0 seconds); the final seed freshness check still waited on the lock on 12/14 (median 8.3 seconds). Publisher-resource median fell 29.75→21.2 seconds against the earlier baseline. Runner speed and upstream readiness also varied, so the full resource difference is not a causal wall-time estimate. Earlier paired runs measured tool-install medians 16.5→13 seconds and observability 98.5→60 seconds; all collectors remain.
Whole-job median latency is effectively unchanged against the prior PR baseline. In the earlier pre-removal run, non-typed time was a median 422.5 seconds per shard. That run’s step medians included 83 seconds waiting for the producer, 153.5 seconds in baseline bring-up, 62.5 seconds creating Kind and 58 seconds installing observability. These medians are not an additive critical-path model. Completion spans include producer waits, cache warmth, host variance and staggered starts; the 243-second typed maximum is not the full PR gate's duration.
The worker dependency stage measured 10.773 seconds cold and 0.447 seconds warm locally on ARM64. This is not a full-worker x86 CI saving; the new remote cache scope remains cold until trusted main publishes it.
Severity and risk
Severity does not apply: test cost and diagnostic-quality improvement. The risks are weakened coverage during consolidation and flakes from shorter observation windows. Independent controls, distinct assertions, and real safety windows address those risks; shorter negative probes still have the limits of bounded observations. The CI observability layout is for fresh clusters and does not migrate existing node-bound volumes; ordinary local development retains the full layout. Cleanup failure remains a test failure, with HTTP error bodies retained. SQL and protobuf contracts are unchanged. Revert this PR to restore the previous inventory and behavior.
Not covered
The canonical known gaps describe live IMDS precedence through the installed gateway/nft path, deployed negative ingress authorization, and browser console scenarios withheld by CI. Unit decisions, rendering snapshots and positive traffic do not establish those missing runtime checks. No bypass was demonstrated. The tier moves above change validation cadence; they do not establish equivalent PR coverage.
