SessionSummary (updatedAt/title/firstPrompt) and SessionPersistence.update() were dead state: zero production callers of update(), no production reader of updatedAt/firstPrompt, and ACP's title comes from a tool-call presenter, not storage. The live Session.header was already typed SessionHeader, so the summary only ever existed in the persistence layer, written and read by nothing but its own contract test. Delete it entirely (no SessionMeta alias — SessionMeta collapses to SessionHeader everywhere). This removes the JSONL .summary.json sidecar machinery, the SQLite title/first_prompt/updated_at columns and per-append updated_at bump, and the update() method from the abstract service and both backends. SQLite SCHEMA_VERSION goes 1->2 and openDatabase now rejects any non-current user_version (older or newer) — no migration, unreleased software. Net -400 lines, and it erases the JSONL-sidecar-vs-SQLite-column durability divergence that the upcoming write coordinator would otherwise have to model. Records the decision in docs/rfc/implemented/2026-06-19-drop-mutable-session-summary.md and migrates the 2026-06-14 session-persistence RFC's facts to current truth. Adds a standalone AGENTS.md section "Tests document behavior, not golden truth" (a passing test pins current behavior, not necessarily correct behavior) with the summary-drop as its worked example, and reinforces the no-migration pre-release stance.
