Overview

Cycle 31 implements persistent storage for TextCorpus, enabling semantic search indexes to be saved to disk and loaded across sessions.

Implementation

Binary File Format

[count:u32]                    # Number of entries
[entry_1]                      # First entry
  [trit_len:u32]              # Vector dimension
  [trits:i8 × trit_len]       # Trit data (-1, 0, +1)
  [label_len:u8]              # Label length
  [label:u8 × label_len]      # Label string
[entry_2]                      # Second entry
...
[entry_N]                      # Last entry

API

// Save corpus to file
pub fn save(self: *TextCorpus, path: []const u8) !void

// Load corpus from file
pub fn load(path: []const u8) !TextCorpus

Generated Functions

// From vsa_imported_system.vibee
pub fn realSaveCorpus(corpus: *vsa.TextCorpus, path: []const u8) !void {
    try corpus.save(path);
}

pub fn realLoadCorpus(path: []const u8) !vsa.TextCorpus {
    return vsa.TextCorpus.load(path);
}

VIBEE Specification

Added to specs/tri/vsa_imported_system.vibee:

# CORPUS PERSISTENCE
- name: realSaveCorpus
  given: Corpus and file path
  when: Saving corpus to file
  then: Call corpus.save(path)

- name: realLoadCorpus
  given: File path
  when: Loading corpus from file
  then: Call TextCorpus.load(path)

---

Critical Assessment

Strengths

1. Compact binary format - No JSON parsing overhead
2. Direct trit storage - 1 byte per trit, fast read/write
3. VIBEE integration - Auto-generated wrappers

Weaknesses

1. No compression - Could use run-length encoding for trit sequences
2. No versioning - File format lacks version header
3. Test coverage - File I/O tests simplified due to test runner limitations

---

Tech Tree Options (Next Cycle)

Option A: Compressed Corpus Format

Add RLE or packed trit compression to reduce file sizes by ~60%.

Option B: Incremental Updates

Append-only mode for adding entries without full rewrite.

Option C: Memory-Mapped Corpus

Use mmap for large corpora to avoid loading entire file.

Files Modified

File	Changes
src/vsa.zig	Added save(), load() to TextCorpus
src/vibeec/codegen/emitter.zig	Added realSaveCorpus, realLoadCorpus generators
src/vibeec/codegen/tests_gen.zig	Added persistence test generators
specs/tri/vsa_imported_system.vibee	Added persistence behaviors
generated/vsa_imported_system.zig	Regenerated with persistence

Conclusion

VERDICT: IMMORTAL

Persistent corpus storage enables semantic search indexes to survive across sessions. The binary format is compact and fast. Ready for Cycle 32.
