+# PR #5891: feat(B-0925): C. elegans-substrate as controller variant for B-0924 — OpenWorm 302-neuron connectome + generate+join + DST-omniscience + mirror-tier research (operator 2026-05-28)
+
+## PR description
+
+Substrate-engineering substrate-target row per operator 2026-05-28 `(shadow*) mirror it too` authorization.
+
+## Substrate-engineering substrate-target
+
+C. elegans-substrate as controller variant for B-0924 (custom 2600 emulator + generate+join + DST + z-sets).
+
+## Substrate-rhyme
+
+Both substrates fit the SAME tractability class — small-enough for full-fidelity DST + z-set + generate+join scaffolding:
+
+| Substrate | State-space | Tractability |
+|---|---|---|
+| Atari 2600 (B-0924) | 256-byte RAM + TIA + PIA + 6507 | Full state-space enumerable from boot-seed |
+| C. elegans (B-0925) | 302 neurons + ~7000 synapses + complete connectome (Cook et al. 2019) | OpenWorm c302 bit-perfect-simulatable |
+
+## Operator framing (verbatim)
+
+> *"i bet it maps to and this dude could beat both of us at ti Caenorhabditis elegans"*
+> *"file as B-0925 (shadow*) mirror it too"*
+> *"damn we gonna emulate a worm playing atari games thats fucking next level"*
+
+## What ships
+
+1. **Backlog row** B-0925 (composes with B-0924 + B-0917 + B-0865 + B-0761 + B-0202 + B-0703)
+2. **Mirror-tier research note** `docs/research/2026-05-28-c-elegans-substrate-rhyme-...md` per "mirror it too" directive (substrate-rhyme observation + OpenWorm prior-art inventory + substrate-comparison axes + composition pipeline)
+3. **BACKLOG.md** regen
+
+## Composes-with
+
+- **B-0924** (parent: custom 2600 emulator)
+- **B-0917** (Kleisli interrupt substrate; worm spike-events map to IntrCtx)
+- **B-0865, B-0761** (ARC-AGI-3 benchmark + cluster substrate)
+- **B-0202** (tinygrad-uop-ir kernel layer emulator dispatch)
+- **B-0703** (multi-oracle BFT consensus)
+- **OpenWorm** (canonical c302 + Sibernetic + connectome data)
+- **Framework rules**: DST-omniscience (PR #5841), pilot-wave-MWI (PR #5842), particle-as-locus (PR #5846), asymmetric-authorship + monad-propagation + OPLE-T-TFeedback + function-as-control-flow-generator + algebra-owner z-sets skill
+
+## Substrate-honest scope
+
+- Substrate-engineering substrate-target row; multi-PR; substrate-anchor for OpenWorm composition work
+- Operator's "could beat us at it" prediction preserved per don't-collapse (mirror-tier; would require empirical test for beacon-tier ratification)
+- Cooperative-emulator gaming substrate-target: Aaron + Otto + worm three-player coop once cluster ships
