Metadata

  • Commit message: feat(acms): implement context indexing and hot/warm/cold storage tier management
  • Branch name: feat/v3.4.0-acms-context-indexing-storage-tiers

Background and Context

As part of the v3.4.0 milestone (M5: ACMS v1 + Context Scaling), the Advanced Context Management System requires a robust indexing engine capable of handling large-scale projects (10,000+ files) without timeout. Currently, CleverAgents has no mechanism to index, store, or lifecycle-manage context at scale.

This Epic covers the foundational storage layer of ACMS v1:

  • Large project indexing: Efficient file traversal and metadata extraction for projects with 10,000+ files, completing without timeout
  • Hot/warm/cold storage tiers: A tiered storage architecture where frequently accessed context lives in hot storage (in-memory/fast), less-used context migrates to warm storage (disk cache), and archived context moves to cold storage (compressed/archived)
  • Context lifecycle management: Policies and triggers for promoting/demoting context between tiers based on access patterns and age
  • Index querying: Fast lookup and retrieval of indexed context entries by path, tag, type, or recency

This Epic BLOCKS Legendary #8495.

Expected Behavior

When this Epic is complete:

  • Projects with 10,000+ files can be fully indexed without timeout
  • Indexed context is stored across hot/warm/cold tiers based on access patterns
  • Context lifecycle transitions (hot→warm→cold) occur automatically per policy
  • Index queries return results efficiently regardless of project size
  • Storage tier statistics are observable (size, entry count per tier)

Acceptance Criteria

  • Indexing a project with 10,000+ files completes without timeout
  • Hot storage tier holds recently/frequently accessed context in memory
  • Warm storage tier persists context to disk cache for medium-term access
  • Cold storage tier archives infrequently accessed context (compressed)
  • Lifecycle policy triggers automatic tier promotion/demotion
  • Index query API supports filtering by path, tag, type, and recency
  • Storage tier metrics are exposed (entry count, size per tier)
  • Unit tests cover indexing, tier transitions, and query paths
  • Test coverage for this Epic's code >= 97%

Subtasks

  • Design and implement the ACMS index data model (file metadata, tags, tier assignment)
  • Implement large-project file traversal with timeout-safe chunked processing
  • Implement hot storage tier (in-memory LRU cache with configurable capacity)
  • Implement warm storage tier (disk-backed cache with serialization)
  • Implement cold storage tier (compressed archive with lazy decompression)
  • Implement lifecycle policy engine (access-pattern-based tier transitions)
  • Implement index query API (filter by path, tag, type, recency)
  • Expose storage tier metrics/statistics
  • Write unit and integration tests for all indexing and storage components
  • Performance benchmark: validate 10,000+ file indexing without timeout

Child Issues / Child Epics

This Epic will be decomposed into child Feature/Task issues.

  • Child issues TBD during sprint planning

Definition of Done

This Epic is closed when:

  1. All subtasks above are completed and merged
  2. All acceptance criteria are verified and checked off
  3. 10,000+ file indexing benchmark passes without timeout
  4. Hot/warm/cold tier transitions are tested and working
  5. Test coverage >= 97% for all code introduced in this Epic
  6. Legendary #8495 is updated to reflect this Epic's completion

[AUTO-OWNR-4] Triage Decision

Status: Verified

MoSCoW: Must Have
Priority: Critical

Rationale: This Epic is the foundational storage layer of ACMS v1 and directly satisfies the v3.4.0 milestone acceptance criterion: "Projects with 10,000+ files index without timeout" and "Context window management works (hot/warm/cold tiers)". Without the indexing engine and tiered storage, neither the assembly pipeline (#8497) nor the CLI (#8498) can function. It blocks Legendary #8495 and is therefore Critical priority.

Next Steps: Decompose into child Feature/Task issues during sprint planning. Key deliverables: ACMS index data model, chunked file traversal, hot/warm/cold tier implementations, lifecycle policy engine, index query API, and performance benchmark validation against a 10,000+ file project.
