Why: The multi-instance acceptance test still created alice with a literal
password; backend U3 replaced local password-bearing creation with trusted
pending-account activation, so the first pin bump past U3 failed test-pg
with RECOVERY_CONTRACT_REPLACED. The seam was left pending by the U3 task
and this PR is the first to cross it.
Evidence: Full TestTwoInstancesOverSharedPG passes against a disposable
PostgreSQL 16 container (identity ensure -> bootstrap-admin -> pending
create with activation key -> key redemption -> grant-setup password ->
api key -> all cross-instance scenarios, 15s).
Impact: Test-only bootstrap rewrite (deployment-level identity ensured once
per pair, admin bootstrapped first, alice activated through the key
redemption and grant-setup password flow); no product code changes.
Refs: Dev task feature/pptx-gate-reference-integrity; backend U3 #198
Why: The follow-up CI exposed that backend #188 broke the Dev
multi-instance suite: serve --mock seeded runtime.mock at the user
scope, which system-managed settings now reject, so instances never
became healthy. Backend #190 seeds the startup flag into the system
scope; this PR repins and drops the now-invalid alice user-scope write.
Evidence: Backend #190 CI success at head 0af1ebc (GATE); this PR's
composite CI re-runs make test-multi-instance (GATE for the fix).
Impact: backend pin 741da4a; multi-instance test comments updated to
the system-managed regime.
Refs: Backend #188, #190.
Why: an unset object store must keep artifact bytes available to the other process, which the store-level test does not execute.
Evidence: cross_artifact_roundtrip failed with EOF on backend c6fb130 and passed on 46073d30 (SELF, isolated u7drill-k4).
Impact: Dev now builds the fixed backend. Second-instance write traffic stays closed.

Why: Backend login_keys gate blocks Key traffic while
must_change_password is set; U7 failed on PUT settings/user 403.
Evidence: go test -c multi-instance compiles; CI test-pg will GATE.
Impact: loginAlice does session password change alicePass0→alicePass.

Why: collaboration storage U7 (proposal sections 3/5/7) requires two-process
HTTP-level acceptance over shared PG, a reproducible load-test entry honoring
the load contract, and an auditable pre-release checklist; capacity windows and
dual-host runs need user-scheduled resources, so the deliverable here is the
verifiable entry, not capacity claims.
Evidence: make test green (composite); make test-multi-instance green locally
against an isolated PG (five scenarios incl. crash-takeover and restart
invariants); run_load.sh --profile smoke end-to-end green (SSE probe p95~18ms,
zero seq duplicates, stack auto-recycled); backend pinned to feature branch
with the three cross-instance fixes.
Impact: new tests/integration/multi-instance (CI test-pg job step), new
tests/load/collaboration (k6 + SSE probe + run_load.sh), release checklist at
docs/release-multi-instance.md; no runtime behavior change in Dev repo itself.
