The reconstructability RFC is the principle's home: model-visible ⟺ logged in both forms, the mechanism (boundary derivation + header fold), the enforcement (write-time round-trip guard, the dev invariant), the corollaries ranked (prefix-cache stability first), the MiniCode lineage with the provenance arrow inverted, and the alternatives it beat — including the stateful transmission client whose three-design archaeology lives in PR #162. Placements per the one-home-per-fact taxonomy: a standing-order line in root AGENTS.md (with displacement trims to stay inside the 1,575-word ceiling), the principle statement in architecture.md § Session Log and its Turn Flow lines (condensed to the ratcheted 1,630 ceiling), the request-envelope section in core-data-structures/core.md with the LlmCallConfig paste, both review-requested FIXMEs (FIXME(call-config-shape) beside the type, FIXME(catalog-verbs) at the catalog's drift-gate note), cookbook rows redirected off agent/request (tool filtering → system-prompt/assemble, plan-mode prompt → sections/ inject()), and the llm/stream JSDoc stating the frozen-request contract. RFC index and all generated catalogs regenerated.
