+# Semion participation in persistent-agent research
+
+Program: `ABX-NOEMA-REP-001`  
+Status: proposed / SHADOW / ADVISORY_ONLY  
+Date: 2026-09-14  
+Scope: specification review only; no runtime or permission change.
+
+[Shared program draft](https://github.com/scrimshawlife-ctrl/Abraxas/blob/codex/persistent-agent-program-20260914/docs/research/persistent-agent-program/spec.md) owns cross-repository experiment coordination, workflows WF-P01 through WF-P05, acceptance AC-P01 through AC-P10, and the candidate sidecar. This document owns only this repository's participation mapping. The program is not a new specialist or a replacement for existing contracts. Draft branch links are review links; pin the accepted commit when adopted.
+
+## Existing authority
+
+[Constitution](../constitution.md), [Spec 001](001-semion-triad/spec.md), [Spec 002](002-corpus-adapt/spec.md), [Spec 003](003-semiosis-chain/spec.md), [Spec 004](004-encoder-gate/spec.md), and [proposed contract catalog](contracts.md) remain distinct authorities. Existing T0 behavior is not proof of the proposed methodology. Noema remains a separate system. Semion is one specialist in the shared Abraxas research program.
+
+## Ownership and contract mapping
+
+| Input | Operation | Output / boundary |
+|---|---|---|
+| Permitted sign/corpus atom from an approved export | Existing corpus adapt, then T0 classification | semion.frame.v0; source identity/hash retained in external sidecar |
+| Sign form with supported label/object evidence | Interpret representamen/object/class under existing rules | Inference labels retain their evidence class; no human/model mental-state claim |
+| Eligible frame for an approved consumer | Existing export compatibility mapping | Consumer conformance requires its actual schema; name similarity is insufficient |
+| Mixed slang/sign material | Existing upstream route review | Hyperlex handles lexical form; do not send bare slang/forecast packets to Semion |
+
+No program field is added to semion.frame.v0. Missing object, unsupported classification, disputed provenance and ambiguous consumer mapping remain bounded failures/NOT_COMPUTABLE. A classifier-supplied interpretant is not an executed world action or a measured behavioral consequence. Link to independently observed Noema events only through the external experiment mapping.
+
+## Workflows and traceability
+
+J-P03 -> WF-P03 -> CAPTURED/ANALYZED or BLOCKED -> existing atom/frame contracts -> AC-P05/AC-P06 -> T-SEM-P01. J-P04 -> WF-P04 -> REVIEWED_RESULT or INCONCLUSIVE -> frozen evaluation evidence -> AC-P08 -> T-SEM-P02.
+
+T-SEM-P01: specify exact permissible Noema export-to-atom field mapping and fixtures before implementation. Test sign and corpus inputs, missing object, wrong lane, tampered source, and absence of consumer schema. Preserve forecast_eligible=false, phenomenal=false, brier=null; no route binding change.
+
+T-SEM-P02: define paired T0/candidate evaluation only after the selected snapshot and feature protocol are approved. Preserve train/test provenance separation, source rights and label evidence. Gold class labels must not leak into predictive features. Report annotation adaptation separately from predictive classification.
+
+## GPU and training eligibility
+
+The initial integrated case uses existing T0 classification. It makes no Semion GPU need claim. Later encoder training is a separately authorized workload subject to Spec 004, dataset selection, T0 comparison and operator approval. Historical Notion counts/pack reports are not independent inspection of corpus bytes. name_gate remains false absent the required evidence; training, weights and Hub do not open through this note. Preserve the one-concept-per-cycle rule: packet/schema adaptation and encoder work remain separate cycles.
+
+## Verification and unresolved evidence
+
+Run existing Semion tests and any available methodology checks; check local links and git diff --check. No Noema export adapter, new model run, encoder comparison, rights validation or external consumer conformance is claimed here. Those acceptance outcomes are NOT_COMPUTABLE until their receipts exist. Existing DEC entries in the methodology remain unresolved by this program.
