Records Phase 8 and answers §7.1 Q8, leaving Q9 as the only open question.
ENGAGEMENT.md gains the phase's as-built section: the four decisions settled
first, the relative-url finding the live rig caught (Phase 7's contract is
relative-only, and the client half of that contract was never written down), the
ref-not-stream routing rule, the (base URL, user id) snapshot scoping that is the
actual security property, and the on-device walk. Its Status paragraph was six
phases stale and now names every phase that has landed.
android/PLAN.md §7's "no offline caching, no Room in v1" decision STANDS and now
names its one exception, with the limit it comes with: the snapshot serves a
running app, not a cold start, because the shell gates the whole app on loading
the site's appearance. Widening Phase 8 into the shell's startup model is the
org lead's call, so it is written up rather than done. §11 gains the inbox and
the per-channel screen as built.
