The @backspace/desktop postinstall runs `electron-rebuild -f -w uiohook-napi`,
which compiles a native module from source and needs a C++ toolchain
(make/g++/python3). On a bare host without those — a typical VPS a self-hoster
clones onto — that failure took the ENTIRE `pnpm install` down (exit 255), so the
server never installed either, even though uiohook-napi is desktop-only and
irrelevant to hosting.
Make the rebuild non-fatal: on failure it now prints a clear one-line warning and
continues. Machines with build tools (CI, desktop devs) are byte-identical — the
fallback never fires; only toolless boxes (which aren't building the desktop app
anyway) skip it. Verified on a bare x86 box: full `pnpm install` now exits 0 and
the server builds and boots from source. Docs note the build-tool requirement for
desktop work and point self-hosters at the Docker installer.
A reset peer reaches needs_attention via the auth-failure path (HMAC desynced by
the new incarnation) without passing through unreachable, so the 5s recovery
probe never saw it — detection waited up to a full 15-min health-check cycle
before 'Re-peer & heal' surfaced. Extract detectResetForPeer() and fire it
event-driven at the transition, plus a startup sweep for already-stuck peers.
15-min tick remains the backstop.
Also add the positive companion assertion (folded in from a Task 3 review
Minor): findFederatedUser tier-2 STILL returns a NON-detached (orphaned=0)
same-name federated row, locking that the eq(federation_home_orphaned, 0)
clause discriminates on the flag alone and never over-filters legitimate
replicated identities.
All three behaviors pass against the shipped Task 1-3 code; no product-code
change was required.
Finding 1: handleReactionAdd/Remove now drop reactions on a dead 1-on-1
(isDeadOneOnOne) — previously a survivor could react on a Deleted-User
thread and the relay fanned out to all peers via undefined target-origins.
Client Message.tsx withdraws add/toggle reaction affordances for dead DMs
(existing reactions still display read-only).
Finding 2: dmMembership purge test now runs with foreign_keys=ON (matches
prod) and asserts dm_members/dm_messages cascade cleanup on channel purge.
Finding 3: tombstone group-DM ownership transfer filters isDeleted=0 so
ownership can never move to a tombstoned member; covered by a new test.
#1 control passes (harness validated); #2 fails (200 vs expected 409 — false success);
#4 fails (s2sHealthy false — Re-peer reports success on dead peering). Turned green by the fixes.
lookupRemoteUser now maps peer HTTP failures (403/5xx, malformed body) to a
structured {ok:false,reason:'unreachable'} instead of throwing, and the
federated friend-add wraps the call in try/catch as defense-in-depth. A
desynced/unreachable peer no longer surfaces as a raw 500 on a user action.
README.md left unstaged.
