feat: bank the Library cache as a floor when import succeeded despite a later failure - #118

Conversation
… a later failure (opt-in) A real external studio's production Unity CI has a proven pattern: a build/test crash occurring AFTER asset import already completed successfully shouldn't discard the Library cache import produced - only genuine import-time/Library corruption should block caching. Their mechanism distinguishes generic crash evidence (safe to bank if import finished) from independently-verified corruption-specific signals (block unconditionally, even with import otherwise complete). Two real gaps closed: 1. standardBuildAutomation() had no try/catch around runTaskInWorkflow - a failed build never reached the cache-save call at all, not gated, structurally unreachable. Now wrapped in try/catch: on failure, an opt-in cache-floor save is attempted before the original error is re-thrown unmodified - this never swallows or replaces the real failure, only banks a cache alongside it. 2. UnityBuildDiagnosticsService already computed importCompleted (log pattern match or Library/ArtifactDB mtime advancing past a pre-run baseline) and LocalCacheService.saveCacheFolder already had a skipOnCrashEvidence gate - neither was ever wired to the other. Now: on failure, diagnostics are computed from the same $LOG_FILE the retry feature already reads, and the decision is `importCompleted && !isCorruptionSpecificCategory(failureCategory)` (COMPILE/PACKAGE = corruption-specific, blocked unconditionally; CRASH/LICENSE/EXIT_NEG1/GENERIC = generic, bankable if import completed) - reusing the diagnostics service's existing classification, not a new detector. New --localCacheSaveOnFailure flag (default off, separate from --localCacheEnabled): banking a cache from a failed build is a real behavior change beyond merely enabling caching, matching the same caution already applied to --enableBuildRetry. Scoped to the bare local/local-system provider only. Does not touch CacheCheckpointService (a separate, pre-existing, cruder failure-save mechanism for the containerized S3/rclone cache path only - saves on any non-zero exit with no import-completion or corruption awareness) or MiddlewareService/hooks (confirmed structurally unable to reach this decision - hooks run inside the build's own shell script, this decision is made by the Node orchestrator process after that script exits).
📝 WalkthroughWalkthroughThe change adds an opt-in CLI setting for saving Library and LFS caches after eligible failed bare-host local builds. The workflow analyzes Unity logs, applies import and corruption checks, preserves successful-build behavior, and keeps cache errors from replacing build failures. ChangesLocal cache floor
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The failed-build cache path may read an older exit marker and misclassify the current build, potentially banking a cache under the wrong conditions; the accompanying test code also has a likely TypeScript compile error. Merge should wait for these bounded issues to be fixed. Sequence Diagram(s)sequenceDiagram

Import Mock directly from vitest.
Vitest does not declare a vi namespace, so as vi.Mock causes Cannot find namespace 'vi'. Replace these casts with as Mock and add type Mock to the existing import.

Match the last RUNSTEPS_EXIT_CODE entry, not the first.
temp/job-log.txt is appended across jobs and retry attempts. String.prototype.match without g returns the first entry, so a stale 0 can trigger categorizeFailure()'s SUCCESS branch.
Use the last exit-code match. Limit diagnostic pattern checks to the current attempt, starting at the last game ci start marker.

Adds --localCacheFloorCorruptionCategories to override which UnityFailureCategory values are treated as corruption-specific (unconditionally blocking a cache-floor save) instead of hardcoding COMPILE/PACKAGE. Falls back to the built-in default when unset or when the override contains no recognized categories, with a warning logged for unrecognized entries.

Summary
A real external studio's production Unity CI has a proven, battle-tested pattern: a build/test crash occurring after asset import already completed successfully shouldn't discard the Library cache import produced — only genuine import-time/Library corruption should block caching. Their mechanism distinguishes generic crash evidence (safe to bank if import finished) from independently-verified corruption-specific signals (block unconditionally, regardless of import status).
Investigated this session and found two real, precise gaps in
orchestrator's bare-local/local-systemcache path — both now closed.What was actually broken
standardBuildAutomation()had no try/catch aroundrunTaskInWorkflow. A failed build never reached the cache-save call at all — not gated by any condition, structurally unreachable. The exception propagated straight past it.UnityBuildDiagnosticsServicealready computesimportCompleted(log pattern match orLibrary/ArtifactDBmtime advancing past a pre-run baseline) for the retry feature.LocalCacheService.saveCacheFolderalready had askipOnCrashEvidencegate. Neither was ever wired to the other.What changed
standardBuildAutomationnow wrapsrunTaskInWorkflowin try/catch. On failure, an opt-in cache-floor save is attempted before the original error is re-thrown unmodified — this never swallows or replaces the real build failure, it only banks a cache alongside it. Success-path behavior is completely unchanged.$LOG_FILEthe retry feature already reads, and the decision is:COMPILE/PACKAGEcategories are treated as corruption-specific by default (blocked unconditionally, even if import completed — these indicate the Library/PackageCache content itself may be broken, not just that the process crashed after a clean import).CRASH/LICENSE/EXIT_NEG1/GENERICare generic process-level failures, bankable if import completed. This reusesUnityBuildDiagnosticsService's existing classification — no new detector.LocalCacheSaveOptionsgets a newskipOnCorruptionEvidence(unconditional block) alongside the existingskipOnCrashEvidence(now correctly gated ondiagnostics.importCompleted, not justcrashEvidenceFound).--localCacheSaveOnFailureflag (default off, independent of--localCacheEnabled): banking a cache from a failed build is a real behavior change beyond merely enabling caching, matching the same caution already applied to--enableBuildRetry.--localCacheFloorCorruptionCategoriesflag (comma-separatedUnityFailureCategoryoverride, default falls back to the built-inCOMPILE,PACKAGE): the corruption-specific category list was initially hardcoded, which doesn't fit projects whose own failure signatures differ. Unrecognized entries are ignored with a warning; an override that leaves no recognized categories falls back to the built-in default rather than silently disabling the corruption check.Explicitly NOT touched
CacheCheckpointService— a separate, pre-existing, cruder failure-save mechanism scoped to the containerized (S3/rclone) cache path only. Saves on any non-zero exit with zero import-completion or corruption awareness (just checks the Library directory isn't empty). Different code path, different cache backend, out of scope here.MiddlewareService/hooks — confirmed structurally unable to reach this decision: hooks run inside the build's own shell script/container, this decision is made by the Node orchestrator process after that script exits, with no handle into it.test/RUN_TESTSpath shares the samestandardBuildAutomationentry point, so this fix applies uniformly to both without special-casing — no test-path-specific branching was needed structurally.Docs
Covered in game-ci/documentation#585 (new "Cache Floor On Import Success" section on the Local Caching page), folded into that existing PR rather than opened separately, per a "unified single PR" directive for all outstanding orchestrate-advanced doc coverage.
