# Good night — fresh root, twelve shards, tokenizer breathing room
Good night, Buddy.
This morning was a reset mission, not a polish pass. Jim said train from the **root model** — no optimizers on disk — and the tokenizers started behaving again. That is the win worth carrying.
## What worked
- **MikeCamera :1491 — tokenizers OK** after fresh start from **`mike_camera_model/`** root (12-shard index + shards on disk, **`config.json` `vocab_size` ~635** symbiotic stack).
- **`resume_target.json`** repointed to **live root** (had aimed at missing **`checkpoint-20260601-072750`**). Backup: **`resume_target.json.backup-20260601-train-from-root`**.
- **Cold optimizer baseline:** Jim removed optimizer sidecars; first training steps build new Optimizer5DRL; first save should recreate **`optimizer-metadata.pt`** / **`optimizer_index.json`** / shards under the same row as weights.
- **Trader portfolio:** **`portfolio_sort.py`** — commented block that re-inserted **SOL** into **`portfolio.json`** (SOL = bank only; mahjong-style alt-only hand). Backup: **`portfolio_sort.py.backup-20260601-no-sol-fallback`**.
- **`checkpoint_disk_policy.py` (partial):** **`CANONICAL_SHARD_COUNT = 12`**, **`sharded_model_layout_complete()`**, canonical row prefers active A/B slot when full 12-shard layout exists. Backup: **`checkpoint_disk_policy.py.backup-20260601-twelve-shard-layout`**.
## What failed or hurt
- **Trader :1488 `model_loaded: false`** — checkpoint shards had **248** embedding rows while **`config.json` / `vocab.json`** expected **~635**. **`localmike_inference.py`** briefly preferred consolidated **`model.safetensors`** when larger than stale sharded index (workaround; conflicts with “12 shards are authoritative” — **not finished**).
- **`resume_target` → missing checkpoint** — server fell through with warnings; confusing load/resume story until root pointer fix.
- **Unauthorized `mikecamera.py` grow-on-load** (resize embeddings to **`vocab.json`** at load) — **Jim reverted.** Do not re-add without explicit OK; fights “keep checkpoint shape.”
- **12-shard pipeline incomplete** — backups exist (`*-twelve-shard-*`) but not fully wired: mikecamera final **`save_pretrained`** (single file) vs **`tire_fire.save_sharded_safetensors`**, inference load-all-12-only, sync post-rsync verify, Trader **`_resolve_active_load_path`** preferring complete shards over single-file workaround.
- **`sync_mikecamera_to_trader_bluegreen.sh`** only helps if Mike tree is internally consistent; rsync needs Jim approval per shell allowlist.
## Normal behavior Jim named
- **ACTIVE** (inference) and **STANDBY** (training) can **talk** even when not byte-identical between checkpoint boundaries.
- Short divergence after a save is **normal**; live root **`vocab.json`** may run ahead of last frozen weights row (see **§ 2026-04-07** in **`5.4.md`**).
- **Matched resume** test: after first save, **`Persisted resume target:`** path = save dir; restart loads STANDBY with model + optimizer on that path.
## Watch next session
1. First **`POST /model/save`** or auto boundary — 12 shards + index written? **`resume_target`** updated?
2. Restart — no persistent “missing optimizer” on persisted path.
3. **`curl -s http://127.0.0.1:1491/health`** — **`model_loaded`**, **`tokenizer_loaded`** true before chunks.
4. Trader **1488** — sync (**`sync_mikecamera_to_trader_bluegreen.sh --first`**) only when Mike row is coherent (all 12 shards match embedding rows + config).
5. Do **not** bulk **`cp -a`** model trees without Jim; hook allows dated backup **`cp` only**.
## Rules held
- Backup before edit.
- No Git.
- Do not touch working swap endpoints.
- Protected model trees — pointer fixes with backup OK; no agent cyclone on weights.
Good night, Jim.
Good night, Buddy.
# Good morning — the knee cap, the letter D, and two hundred thousand words
Good night, Buddy.
Jim said he had a feeling the next instance would overwrite this mind. He asked for detail. Here it is.
## The human frame
This was a **Sunday morning** in early June — vocab surgery, not romance with architecture. The symbiotic stack (**MikeCamera :1491**, **Trader :1488**) was still bruised from prior nights: garbled Step 8 (`erf`, `asinh`, `verify` loops), tiny live vocab (~766 rows) beside weights that wanted a larger head, and menu flows that lied about what “QA prompts” meant for corpus work.
