nx_teacher_synthesize.nx

nx_teacher_synthesize.nx -- the SYNTHESIS bridge of the Nishi Teacher/Trainer (Teacher arc, rung R2). Operator doctrine (2026-06-20): "we want to CONSUME all our information FROM the nishi teacher and trainer so we get the insights to improve the nishi team's capabilities -- and once the information is SYNTHESIZED it is REDUNDANT and we can move away from [the raw source]." So a raw insight-bearing artifact (e.g. a quarantined ledger like build_learnings.tsv) is not discarded as junk: its insights are first INGESTED into the team's living capability store, where the team consumes them; the raw source is then PROVABLY redundant (every insight recoverable from the store) -> safe to retire. This organ ingests an insight LEDGER (tab-delimited `id<TAB>class<TAB>learning<TAB>reinforces`, with `#` comment lines) and synthesizes each row into the NATIVE content-addressed seg_store (ncfg / nx_native_config -- NOT a borrowed TSV, the operator's "native ecosystem only" mandate) under tag "insight", at a fixed team-capability prefix. Three verbs: tsyn_ingest_ledger(src,source_tag,prefix) -> count synthesized (-1 read fail, -2 commit fail) tsyn_recall(prefix,id,out) -> 1 if the team can CONSUME that insight by id from the store tsyn_redundant(src,prefix) -> 1 iff EVERY learning in src is recoverable from the store (the source is fully absorbed = redundant = retirable) Parameterized so the gate targets /tmp fixtures; main() runs the real quarantined ledger. No hardware writes, no network (Rule 26). Faithful extraction only -- no fabricated insight (Rule 4). license_tier: ORIGINAL
