V0M3 made accepted model changes ordinary document revisions, preserving exact operations and lineage so removal, restoration, and explanation remained possible later.

V0M3 used a stable proposal contract without pretending that model providers shared context rules, tool behavior, privacy terms, streaming semantics, or recovery guarantees.
V0M3 treated tool names and descriptions as metadata while server policy determined the capability, resource scope, arguments, and effect actually allowed.
V0M3 invalidated approval when proposal text, operation selection, document revision, evidence, policy, or world preconditions changed.
V0M3 revealed complete proposal operations only after their targets, evidence, schema, and rendering policy validated.
V0M3 became dependable when generated text entered a typed workflow with evidence, revision history, validation, and human ownership.
V0M3 connected source revisions, claims, proposal operations, accepted spans, human edits, and review decisions after ordinary citations stopped explaining the writing process.
React 19's release-candidate Actions improved mutation ergonomics, while V0M3 kept authority, receipts, conflicts, and recovery in its document workflow.
V0M3 replaced generated blobs with typed insert, replace, delete, move, and comment operations whose claims and targets could be judged independently.
V0M3 bound every assistance request to exact document state so a proposal could not land on text that changed while generation was running.
V0M3 kept the canonical document under explicit human control by making model output a typed proposal that could be reviewed, changed, rejected, or accepted.
V0M3 began when a useful generated paragraph lost its sources, task, prompt, and review state the moment I pasted it into a document.
Server-first components moved data access and rendering, but K81R still had to design navigation, loading, accessibility, errors, readiness, and browser cost.
K81R stored immutable question, evidence, model, prompt, claims, and verification revisions so refreshed knowledge produced a new answer instead of rewriting history.
K81R split end-to-end answer quality into corpus, retrieval, evidence, generation, and verification stages so improvements could not conceal new failure modes.
K81R kept authorization, retrieval scope, tool capability, citation validation, and output rendering outside model instructions.
