Background: The ACMS requires a well-defined index data model to store file metadata, tags, and tier assignments before any storage tier or query functionality can be built. This is the foundational schema that all other ACMS components depend on, making it the critical-path first step for Epic #8496.

Acceptance criteria:

  • Index entry schema defined with fields: path, size, last_accessed, created_at, tags (list), tier (hot/warm/cold), checksum
  • Data model supports serialization/deserialization (JSON/msgpack) for warm/cold tier persistence
  • Tag system supports arbitrary string tags with efficient lookup
  • Tier assignment field is an enum (hot/warm/cold) with default of hot on insertion
  • Index data model has unit tests with ≥ 97% coverage

Metadata

  • Commit Message: feat(acms): design and implement ACMS index data model with file metadata, tags, and tier assignment
  • Branch: feat/acms-index-data-model

Subtasks

  • Define IndexEntry dataclass/model with all required fields (path, size, last_accessed, created_at, tags, tier, checksum)
  • Implement Tier enum with values: hot, warm, cold
  • Implement serialization/deserialization methods (to_dict, from_dict) for persistence
  • Implement tag indexing structure for O(1) tag-based lookup
  • Write unit tests covering all model operations and edge cases
  • Validate coverage ≥ 97% via nox -s coverage_report

Definition of Done

  • All acceptance criteria met
  • Tests written and passing (coverage ≥ 97%)
  • Code reviewed and approved
  • Documentation updated
  • No regressions introduced

Milestone Assignment

Milestone: v3.4.0 (ACMS v1 + Context Scaling)

Rationale: The ACMS index data model is the foundational schema for Epic #8496 (ACMS Context Indexing & Storage Tiers), which is a v3.4.0 milestone deliverable; assigning to v3.4.0 aligns with the parent epic's milestone.
