Rollover Pipeline

detector.check_all_branches()        # scan AIPASS_REGISTRY.json + external registries
→ _should_rollover(file)             # v1: line_count >= max_lines (600)
                                     # v2: len(sessions) >= max_sessions (20)
→ orchestrator.execute_rollover()
  → create_rollover_backup()         # safety copy to branch/.backup/
  → extract_items()                  # v2: max(excess, 1) oldest entries
  → embed via subprocess             # fastembed (ONNX) in memory .venv
  → upsert in ChromaDB               # content-hash IDs (sha256[:16]), no duplicates
  → trim source file                 # write back with oldest removed

Rollover writes safety copies (rollover_backup_*.json) into <branch>/.backup/ — a shared runtime namespace (see @backup's README for all writers).

Subprocess Isolation

All ML operations (fastembed, chromadb) run via subprocess. The main process never imports these libraries. Python interpreter resolved via _get_memory_python() (env var AIPASS_MEMORY_PYTHON → memory/.venv/bin/python → sys.executable).

---

State-Tabs (*_meta keys)

Every .trinity/local.json and .trinity/observations.json carries inline *_meta banner strings that tell the editing agent what rollover rules apply to each section. Example:

"sessions_meta": "⟦ rollover ON → oldest archived to @memory · keep 15 · summary ≤300 chars ⟧"

Source of truth: memory.config.json — rollover counts (defaults + per-branch overrides) and entry char limits. Tab strings are generated, never hand-written.

Sections: todos_meta (rollover OFF — operational, never trimmed), key_learnings_meta, sessions_meta, observations_meta (all rollover ON).

Two value flows

Scenario	How tabs arrive
Live branches	refresh_all_tabs() walks the registry, renders tabs from config with per-branch overrides, writes them into .trinity/ files. Wired after rollover, sync-lines, and push-templates.
New branches	Templates carry {{TODOS_META}}, {{KEY_LEARNINGS_META}}, {{SESSIONS_META}}, {{OBSERVATIONS_META}} placeholders. spawn_pusher propagates these (unresolved) from memory templates → spawn template sets. At branch creation, @spawn calls render_all_meta_tabs() to get rendered defaults and resolves the placeholders.

Public API

from aipass.memory.apps.handlers.tracking.tab_renderer import render_all_meta_tabs

tabs = render_all_meta_tabs()
# → {"TODOS_META": "⟦ rollover OFF ...", "KEY_LEARNINGS_META": "⟦ rollover ON ...", ...}

Returns defaults (not per-branch overrides) — appropriate for template resolution at branch creation.

Integration Points

Depends on:

• prax — logging via get_system_logger()
• api — API key for symbolic extraction (get_api_key())
• AIPASS_REGISTRY.json — branch discovery for rollover scanning
• External *_REGISTRY.json — scanned via AIPASS_CALLER_CWD

Provides to:

• All branches — rollover archival when .trinity/ files hit limits
• All branches — semantic search across archived memories
• All branches — .trinity/ template distribution and sync

ML dependencies (memory .venv/ only):

• fastembed — ONNX embeddings (model: sentence-transformers/all-MiniLM-L6-v2)
• chromadb — vector storage and semantic search
• numpy

---

Quality

• Tests: 978 passed, 0 failures, 0 skips
• Seedgo: 100%

---

Known Issues

• search requires fastembed in memory .venv/ — fails without it
• rollover status shows 0 branches when registry path not resolved
• memory_threshold_exceeded trigger event registered but never fired
