Instrument every full-content read channel for pages with
classification = vs_nfd (ADR 0023, variant A): SPA state fetch and read
rendering, public JSON content, no-JS shell, expanded embeds, public API
GET (incl. the MCP read_page path and write echoes), attachment download
under the #212 effective classification, all export shapes (markdown,
pond ZIP, account data export, queued docx/odt/pdf at enqueue), and
collab-token issuance as the api-side proxy for the WS join.
Events land in the new read_events table (no FKs — evidence survives
page purges and hard user deletions) with actor, session key
(session:/token:/job:/anon), page, pond, channel and the classification
at read time. Recording failures are NOT swallowed: a failed write
aborts the read (hard failure, the deliberate contrast to AuditService —
decision recorded in ADR 0023 and security.md §Logging, together with
the recorded residuals: content fragments and feeds).
One e2e test per channel proves both the event and its absence for
unclassified pages, plus the hard-failure semantics.
