feat(us11): drop ~55 DEAD env vars + 40 config fields (PR-v5-11)#191
Conversation
BREAKING: engram v5.0.0 US11 — remove config env vars tied to subsystems already dropped in US2/US5/US6/US7/US8/US10 plus US9-leading HyDE/type-lanes. Fields removed from Config struct (40): - Reranking (12): RerankingEnabled, RerankingProvider, RerankingAPIBaseURL, RerankingAPIModel, RerankingTimeoutMS, RerankingBatchSize, RerankingAPIKey, RerankingCandidates, RerankingResults, RerankingAlpha, RerankingMinImprovement, RerankingPureMode - HyDE+expansion (7): HyDEEnabled, HyDEAPIURL, HyDEModel, HyDEMaxTokens, HyDETimeoutMS, HyDEAPIKey, QueryExpansionTimeoutMS - Consolidation/supersession (6): ConsolidationEnabled, ConsolidationThreshold, SupersessionEnabled, SupersessionThreshold, StorePathSupersessionEnabled, WriteMergeEnabled - SmartGC/maintenance (7): SmartGCEnabled, SmartGCThreshold, SmartGCMinAgeDays, MaintenanceEnabled, MaintenanceIntervalHours, CleanupStaleObservations, ObservationRetentionDays - Wiki (3): WikiGenerationLimit, WikiMinSources, WikiDataDir - TypeLanes (2): TypeLanesEnabled, TypeSearchLanes - Dedup/clustering (3): DedupSimilarityThreshold, DedupWindowSize, ClusteringThreshold - Context display (3): ContextShowLastSummary, ContextShowReadTokens, ContextShowWorkTokens - Embedding legacy (1): EmbeddingModel Also removed: SearchLaneConfig type, DefaultTypeSearchLanes var, cloneTypeSearchLanes + mergeTypeSearchLanes funcs, DefaultEmbeddingModel const. Env readers removed from Load(): ~52 total Default() lines removed: all corresponding initializer entries Test functions removed/updated: 8 removed + TestDefault updated Consumer cleanup (cascade fixes for removed fields): - internal/worker/sdk/processor.go: applyWriteMergeDecision simplified to no-op - internal/worker/service.go: removed outer cfg var, HyDE generator returns nil, Dedup config removed (SDK uses fixed defaults) - internal/worker/retrieval.go: type-lane helpers use search.DefaultSearchLanes directly (TypeLanesEnabled → const false, QueryExpansionTimeoutMS + HyDEEnabled removed) - internal/worker/handlers_context.go: ClusteringThreshold replaced with fixed 0.9 default - internal/worker/handlers_system.go: removed reranking/search/maintenance/supersession dashboard config sections (returned in /api/system/config response) Preserved LIVE env vars: ENGRAM_API_TOKEN, ENGRAM_DATA_DIR, ENGRAM_DB_PATH, ENGRAM_URL, ENGRAM_AUTH_*, ENGRAM_VAULT_KEY, ENGRAM_ENCRYPTION_KEY*, ENGRAM_TLS_*, ENGRAM_WORKER_HOST/PORT, ENGRAM_RESTART, ENGRAM_LOG_*, ENGRAM_ENFORCE_SOURCE_PROJECT, DATABASE_DSN, DATABASE_MAX_CONNS, WORKSTATION_ID, Embedding live fields (used by getter functions in config.go). Stats: 7 files changed, 84 insertions(+), 614 deletions(-). Build+vet+tests green across all packages (./internal/..., ./pkg/...). REVERSIBLE. Per Cross-Phase Conventions: C1 (no stubs — direct deletion or fixed default), C7 (CodeRabbit only).
Пошаговое описаниеУдалены механизмы конфигурации и runtime обработки для переопределения типизированных поисковых линий, переранжирования, HyDE, дедупликации, кластеризации, консолидации, суперсессии, write-merge и wiki-генерации. Конфиг-структура значительно сокращена, логика обработки поиска упрощена путём фиксации пороговых значений, и соответствующие проверки конфигурации удалены из инициализации сервиса. Изменения

Code Review
This pull request performs a major cleanup of the application configuration for version 5, removing numerous features and their associated settings, including reranking, HyDE query expansion, maintenance tasks, and dynamic clustering thresholds. These features are either disabled or replaced with hardcoded defaults. A review comment identified an inconsistency in internal/worker/handlers_context.go where clustering was entirely bypassed instead of applying the new fixed default threshold of 0.9, which could result in duplicate observations being injected into the context.

In this handler, clustering has been completely bypassed, which will result in duplicate observations being injected into the context if an observation appears in both the 'recent' and 'relevant' sets.
According to the PR description and the implementation in internal/worker/retrieval.go (line 203), the ClusteringThreshold configuration was intended to be replaced by a fixed default of 0.9, not removed entirely. This inconsistency should be resolved by applying clustering with the fixed default here as well.

| clusteredObservations := clusterObservations(unionObservations, clusteringThreshold) | |
| duplicatesRemoved := len(unionObservations) - len(clusteredObservations) |

Разберите ENGRAM_TELEMETRY_ENABLED через strconv.ParseBool.
Сейчас отключение срабатывает только для точных значений false и 0. Значения вроде FALSE, False или no тихо оставят телеметрию включённой, хотя оператор пытался её выключить.

Здесь отключено не только конфигурирование, но и сама дедупликация.
unionObservations теперь отдаётся как есть, поэтому семантические дубликаты больше не схлопываются, duplicates_removed всегда 0, а trimToTokenBudget() режет уже раздутый список. Если цель PR — убрать только настраиваемый threshold, здесь лучше оставить фиксированное значение, как в internal/worker/retrieval.go.

🛠️ Refactor suggestion | 🟠 Major
Удалите applyWriteMergeDecision, а не держите его как no-op.
Сейчас это фактически заглушка: ProcessObservation всё равно идёт по create-path, но продолжает считать merge_evaluated, писать write-merge telemetry и держать ветки update/supersede. Либо уберите всю цепочку write-merge, либо верните полноценную реализацию.
As per coding guidelines "Complete, working implementations only - no stub code or placeholders".
