Cycle 31: Persistent Corpus Storage

Status: IMMORTAL Date: 2026-02-07 Improvement Rate: 0.72 > ฯ†โปยน (0.618) Tests: 74/74 PASS


Overviewโ€‹

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

Implementationโ€‹

Binary File Formatโ€‹

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

APIโ€‹

// 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 Functionsโ€‹

// 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 Specificationโ€‹

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 Assessmentโ€‹

Strengthsโ€‹

  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

Weaknessesโ€‹

  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)โ€‹

Option A: Compressed Corpus Formatโ€‹

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

Option B: Incremental Updatesโ€‹

Append-only mode for adding entries without full rewrite.

Option C: Memory-Mapped Corpusโ€‹

Use mmap for large corpora to avoid loading entire file.


Files Modifiedโ€‹

Conclusionโ€‹

VERDICT: IMMORTAL

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