docs: multinode gate finished + boot-reconciler self-heal bug found+fixed

.5's 5x gate done: 5/5 iterations, all technically FAIL per run-gate.sh's
tally but only from .5's permanent pruned-bitcoin ceiling (accepted going
in); down to 2 failures/iteration by the end. Found + fixed a real hang
(lnd cached a dead bitcoin-knots IP after a restart) live mid-run.

Separately found a real boot-reconciler bug via indeedhub going stuck on
.116: any genuinely-installed-but-fully-absent app was left stuck forever
unless it was one of 8 hardcoded "baseline" apps. Fix tracked, code change
in the shared working tree pending test confirmation.

+  - ✅ **Gate finished 2026-07-01: 5/5 iterations, technically all "FAIL" per
+    run-gate.sh's tally — but only because .5's pruned-bitcoin limitation
+    (expected, permanent, accepted going in) fails one test every single
+    iteration.** By iteration 4-5 that was down to exactly 2 failures per run:
+    the expected pruned-bitcoin one, plus a reproducible `lnd` proxy timeout
+    (`https://host/app/lnd/`, distinct from the DNS bug below — happened
+    consistently on both of the last 2 iterations, worth its own investigation,
+    not yet root-caused). Iterations 1-3 also hit test-suite bugs since fixed
+    live mid-run (see Tier 0/below) and one ~2h hang (also below) — none of
+    those are real product bugs.
+  - 🐛 **Real hang found + fixed live**: `lnd` cached a dead IP for
+    `bitcoin-knots` after an earlier restart gave it a new container IP —
+    every RPC needing chain data blocked forever (client-side `timeout`
+    wrappers don't reliably kill `podman exec`'s in-container process).
+    Blocked iteration 4 for ~2 hours before diagnosed + fixed (`podman
+    restart lnd`, forces fresh DNS resolution). **Product-level gap, not
+    fixed at the code level**: dependent services should reconnect/re-resolve
+    after a backend container is recreated, not cache indefinitely. Logged as
+    a follow-up, not yet implemented.
+  - Next: bring the rest of the fleet to precondition, then the cross-node
+    federation/mesh/transport suites. This is the literal "next exit
+    criterion" called out in `CLAUDE.md`.
+- [x] ~~**Real bug found + fixed 2026-07-01**: boot reconciler left any
+      genuinely-installed-but-fully-absent app stuck forever unless it was one
+      of 8 hardcoded "required baseline" apps~~ — surfaced by indeedhub's
+      backend containers (minio/postgres/relay) never recovering on .116 after
+      going absent. Root cause: `ensure_running_with_mode()`
+      (`prod_orchestrator.rs`) only called `install_fresh()` for
+      `is_required_baseline_app()` apps in the fully-absent case; every other
+      installed app was left as `Left("absent")` with no path back short of an
+      explicit reinstall. Fixed: self-heal now applies to any app that
+      reaches this point (i.e. already confirmed NOT user-stopped / NOT
+      user-uninstalled earlier in the same function — those markers are
+      properly set/cleared on uninstall/reinstall, so this can't resurrect a
+      deliberately-removed app). Deleted the now-dead
+      `is_required_baseline_app()`, updated/renamed the test that had locked
+      in the old behavior. Compiles clean; test suite run in progress.
+      indeedhub itself not yet manually recovered on .116 — the code fix
+      will self-heal it on the next reconcile tick once deployed there.
