+
+Lab B (U08c D3) tracking fit on the native u08b inputs: source CMA (250 generations) then projected source Adam (500 traversals, 156,500 updates); BEST c0499, FINAL c0500.
+
+| Field | Value |
+|---|---|
+| Status | complete |
+| Identity | session_id `session_20260921_230724_040591`, window_id `sync0316-0630` |
+| Parent | none recorded |
+| Stages | cma, adam |
+| Budget (completed/configured) | cma:  (completed_generations 250, issued_asks 2750, told_asks 2750, center_evaluations 1, physical_failures 0); adam: traversals 500/500, updates 156500/156500 |
+| Labels | BEST adam/c0499, FINAL adam/c0500 |
+| Code revision(s) | `8c03605eb6af291b7face39f6474d84aa513f332`; dirty tree by stage: cma reported clean, adam reported clean |
+| Checkpoint rows | 5568 (`checkpoints.tsv`) |
+| Archived native records | 16,314 per-step history files in 30 tar archives (owner D25); `archives/members.json` lists each member's native path and sha256, and `checkpoints.tsv` still lists every checkpoint file |
+
+## Stages
+
+- **cma** (`native/cma/manifest.json`): "mean over K of compute_final_loss(C, T, A), fresh history per ask (U total_loss / (train_frame - 1))"
+- **adam** (`native/adam/manifest.json`): "R4 SourceWarpObjective stage adam: C over the P measured targets against surface [0:S] with fixed D_C = |V[1]|, T over the genuine pairs with fixed D_T = |M[0]| of their own rows, A never active"
+  - stiffness update: projected: finite raw log Y moved back onto the physical cap after every update (protocol.projected_log_y true)
+
+## Capabilities
+
+- **portable_use**: native model arrays retained; fresh use (canonical q0/v0, zero updates) from a clean local copy is implemented and validated by PR4 on representative checkpoints; Hub fetch pending
+- **interrupted_run_recovery**: restore-only of a nonterminal projected source Adam continuation is implemented (scripts/use_published_phystwin.py restore-continuation; PR4 validated it on A faithful tracking and RT05 projected Adam): it rebuilds the trainer and optimizer state exactly and takes zero updates. That is not a demonstration of continued fitting, which is not claimed
+- **extend_completed_budget**: not supported: the native protocols refuse to extend a finished run's horizon
+- **full_reproduction**: not claimed (D3); dirty-state and environment limits are listed under code
+
+## Limitations
+
+- continuing this fit re-hashes author weights TAPNext++ tapnextpp_512 checkpoint (Google DeepMind TAPNet) (/mnt/data2/magna/belt_perception/results/phystwin_real_rgbd/session_20260921_225630_786148/rt_waft_tapnextpp_refit_01/checkpoints/tapnextpp_512.ckpt); they are not published here (dependencies.json third_party_weights names their source and sha256)
+- historical depth: the run's records name depth_source waft_stereo_dav2l5 but no per-stream digest, so the consumed depth bytes and their publication revision are unresolved; correction ledgers replaced 4 depth paths of this session (6ce5a6472649, c9fa16c0c8ac)
+
+Native records under `native/` are authoritative; `run.json`, `checkpoints.tsv` and `dependencies.json` index them. License: see the repository `LICENSE` and card.
