# 0.1 research preview notes 2026-09-27. This is a versioned research reference, with no canonical admission or production certification. Candidate corpus revision: `8cc7016e1fbcb08b670091a174672fcdd8d07640`. The preview provides a starting guide, transactional and offline decision sequences, eight connected core candidates, nine optional extensions, scoped mechanism mappings, a candidate JSON export and eight disclosed development navigation checks. Existing candidate contracts and evidence maturity are unchanged by packaging. Source traceability passes its bounded documentary review. M1 remains revise/defer; M2/M3 and independent human usefulness remain open. Conflict Copy and Explicit Reconciliation retain separate identities with a conditional relationship. No new external source verification or live inference was performed for this packaging. Storage/receiver validation transferred from WP-0002 T02 to WP-0003 T04. Existing research owners are listed in the manifest. No additional release-blocking residual was identified in the bounded review. Later corrections must retain prior claims in Git, name the affected identities and context, and explain the evidence and changed decision. An incompatible corpus or classification change requires a new version and reviewed manifest; never refresh hashes as a substitute for review. Preserve supersession links when splitting, merging or retiring candidates. Documentation errata must identify the corrected preview and remain distinguishable from new empirical evidence.
