Evidence sharing and engagement MCP guides

Three existing pages updated against deployed backend68fa61f/frontendbb5ccd40. Author p16_frontend, independent conformity research_fix, root quality all favorable. Confirmed7-day default/1–30 day lifetime from readiness, explicit consent, one-evidence internal report without discussion, revoke/retry and local mail composer. MCP uses client-wide read-only cases/reports, zero credit limit, two manager actions, recent authentication,1–365 day key, memory-only display and environment placeholders. Desktop service-key transport not invented; no P13/P19 deployment claim.

Existing checkout used for reversible drafting after automatic review blocked creating a new worktree due to usage limits; no external or protected-state mutation bypassed. The earlier typecheck and Docusaurus build passed before this report was added, so they did not validate the final tree. New anchors and relative links checked; no credentials/examples contain a real secret. Logs: /tmp/profundis-p15-p17-docs-types.log and /tmp/profundis-p15-p17-docs-build.log. Docusaurus update-check filesystem advisory does not affect generated output.
