+## 2026-09-25 — reserve named syntax text at its producer
+
+The [text producer contract](analysis-text-producer-contract-20260925.md) selects
+a separate private route bound to actual carried authority. Reserve raw quoted
+payload P before the existing decoder, then transfer decoded D and release P-D.
+This avoids a duplicate decoder while deliberately allowing conservative
+escaped-input refusal on the new route. Preserve legacy/phase-only diagnostics.
+Count simultaneous key/reference copies and all consumed UUID spellings; drop
+temporary strings before refund. Borrow the ordinary declaration-kind word.
+Keep small scalar state, transfer retained text once into the resolver ledger,
+and independently reconcile it against the existing syntax inventory.
+
+The [verified Windows packet](experiments/analysis-text-producer-20260925/README.md)
+records six new passes, unchanged prior outcomes, initial lint repair and the
+single framework-hint difference in one inherited failure log. Preserve the
+original checker refusal and narrow named-byte amendment instead of weakening
+general comparison. Compiler prologue observations and existing stack controls
+bound evidence only; this adds no universal heap or stack guarantee.
+Entry/metadata growth timing and the remaining scratch inventory require their
+own explicit decision before actual emitted-output acceptance can be enabled.
