fix(mobile): recover and pace live subscriptions by brow · Pull Request #3053 · block/buzz

Tl;dr: avoid a thundering herd of per-channel resubs when reconnecting to relay, which the mobile client has to do most times it is foregrounded.

The burst of resubs would get rate limited, causing some of the subs to fail without recovery, and thus local state of channels to silently fall behind.

This makes mobile follow desktop’s strategy for pacing reconnections, using a prioritized queue.

What changed?

Mobile now recovers live subscriptions after retryable or rate-limited relay CLOSED responses. It ports the existing desktop model: classify terminal versus retryable closures, honor retry hints through a session-owned rate-limit gate, retry with bounded backoff, and replay visible-channel subscriptions first in bounded batches.

Channel refreshes also retain unchanged live subscriptions instead of clearing and recreating them. This is desktop parity, not a new relay policy.

Why?

On reconnect or resume, mobile replayed its retained live subscriptions while channelsProvider independently cleared and recreated roughly the same set, alongside unread catch-up and open-channel requests. The relay allows 50 REQs per 5 seconds, so users in many channels could predictably exceed the budget. In live reproduction, 55 subscriptions produced 9 rate-limit closures, 60 produced 18, and 80 produced 36.

Mobile then treated every live CLOSED as terminal, removed the affected subscription, and never restored it. Channel updates could remain dead until a later session reconstruction. This is the primary causal chain behind BOT-1449.

Desktop already handles this as normal transient pressure by classifying closures, gating and backing off retries, pacing reconnect replay, and retaining unchanged subscriptions. This change brings mobile to the same recovery model while removing the avoidable request burst.

How is it tested?

Full mobile suite: 721 passed, 1 skipped. Analyzer and formatting checks pass. Required CI checks pass.

Added and updated tests cover CLOSED classification, retry hints, rate-limit gating, bounded retry and reset behavior, terminal failures, timer cleanup, history gating, visible-first batched replay, and retention of unchanged subscriptions.

P2 — Restore the previously visible channel when a nested channel route is popped.

ChannelDetailPage sets the session's singleton visible channel on mount, then unconditionally clears it on disposal. Channel links push a second ChannelDetailPage over the still-mounted first page. In an A → B → back-to-A flow, disposing B writes null; A becomes visible again but never remounts, so its effect does not rerun. A subsequent reconnect therefore loses A's first-batch replay priority in _replayLiveSubscriptions.

Please make visibility route-aware (or restore the prior active channel) rather than treating every page disposal as “no channel visible,” and add a navigation-stack regression test covering A → B → pop → reconnect ordering. The current relay test only calls setVisibleChannelId directly, so it cannot catch this lifecycle failure.

Reviewed at exact head fc2f4e5d928d89a1dc7b59de59d8527175af4c63. Mobile CI and all required checks are green; I did not duplicate CI locally.

🤖 Addressed the nested navigation lifecycle: visible-channel priority is now owner-scoped, so popping B releases only B and restores A for reconnect replay. Added regression coverage for A → B → pop → reconnect, route replacement, nested ownership, and stale or out-of-order disposal.

…relay session Closes gaps 3, 4 and 5 of the mobile relay client's connection resilience (block#3224), all in mobile/lib/shared/relay/relay_session.dart. Gap 1 (stall detection) is PR block#3231's and gap 2 (timeouts) needs a design decision; neither is touched here. Gap 3 — reconnect backoff had no jitter. Each scheduled wait is now randomised by ±20% via `_jitteredDelay`, mirroring the desktop's `jittered_duration` (crates/buzz-acp/src/relay.rs). The ladder position `_reconnectDelayMs` stays un-jittered and jitter is applied per scheduled wait, matching the desktop's split between `backoff_step` and the jitter applied at call time. Without this a fleet of clients reconnects in lockstep after a relay blip. Gap 4 — the backoff ladder reset on connect rather than on stability, so a socket that died seconds after connecting reset to base on every cycle: the doubling never accumulated and a flapping link hammered the relay indefinitely. `_handleConnected` now arms a 60s timer (`_stableConnectionMs`, mirroring the desktop's `STABLE_CONNECTION_SECS`) that resets the ladder only if the connection survives; the timer is cancelled on disconnect, pause and dispose. There are three reset sites and only one changed. The two left resetting immediately are deliberate, and each now says why in a comment: - `_handleConnected` (was relay_session.dart:378) — CHANGED to stability-gated. This is the automatic reconnect path and the only one that can self-spin. - `reconnect()` (:311) — unchanged. Caller-driven, so it cannot loop on its own. - `onAppResumed()` (:344) — unchanged. The preceding disconnect was our own backgrounding, not relay trouble, and the user is looking at the app; making them wait out a ladder the relay never asked for would read as a hang. The desktop has no equivalent of the latter two (no app-backgrounding concept), so desktop parity does not decide them; this is the conservative reading, being the smallest behavioural change that closes the gap. Gap 5 — NOTICE frames were dropped by `_handleMessage`, so the relay's explicit "slow down" was discarded. Since gaps 3+4+5 compound, the client could not hear the rate limit it was provoking. NOTICE is now logged via debugPrint, and a `rate-limited:` notice raises the reconnect backoff floor from the relay's own `retry in Ns` hint: absent or sub-2s hints floor to 5s and the value is clamped to `_maxReconnectDelayMs`, both mirroring the desktop's `set_rate_limit_gate`. It takes the maximum against the current ladder, so overlapping notices can never shorten a longer backoff already in place. Gap 5 deliberately feeds the existing `_reconnectDelayMs` ladder rather than introducing a gate object. PR block#3053 (open, unmerged) adds a RelayRateLimitGate driven by CLOSED frames and rewrites `_handleConnected`; it contains no NOTICE handling and no jitter, so these gaps are unclaimed. Routing NOTICE through the ladder keeps this free of a hard dependency on block#3053 while pointing at the same backpressure concept, so NOTICE can be redirected into that gate in a small follow-up if block#3053 lands. Deviation from the work order worth flagging to review: the order specified ±25% jitter as the desktop's value. The desktop's `jittered_duration` actually uses a factor of [0.8, 1.2) — ±20% — so ±20% is implemented for real parity. Tests: 11 new cases in mobile/test/shared/relay/relay_session_test.dart. Each of the three fixes was negative-controlled by reverting only its lib/ change and confirming the new tests fail — jitter neutralised gives a flat 1000ms, the reset-on-connect restored collapses the ladder to 2000 where 4000 is expected, and the NOTICE case removed leaves the backoff at 1000. `Random` is now injectable through the constructor (alongside the existing `httpClient` and `socketFactory`) so the jitter assertions are deterministic rather than timing dependent. Gate from mobile/: dart format --set-exit-if-changed clean, flutter analyze clean, flutter test 834 passed / 1 skipped.

…n relay session Closes gaps 3, 4 and 5 of the mobile relay client's connection resilience (block#3224), all in mobile/lib/shared/relay/relay_session.dart. Gap 1 (stall detection) is PR block#3231's and gap 2 (timeouts) needs a design decision; neither is touched here. Gap 3 — reconnect backoff had no jitter.

Gap 4 — the backoff ladder reset on connect rather than on stability, so a socket that died seconds after connecting reset to base on every cycle: the doubling never accumulated and a flapping link hammered the relay indefinitely. `_handleConnected` now arms a 60s timer (`_stableConnectionMs`, mirroring buzz-acp's `STABLE_CONNECTION_SECS`) that resets the ladder only if the connection survives; the timer is cancelled on disconnect, pause and dispose. There are three reset sites and only one changed. The two left resetting immediately are deliberate, and each now says why in a comment: - `_handleConnected` — CHANGED to stability-gated. This is the automatic reconnect path and the only one that can self-spin. - `reconnect()` — unchanged. Caller-driven, so it cannot loop on its own. - `onAppResumed()` — unchanged. The preceding disconnect was our own backgrounding, not relay trouble, and the user is looking at the app; making them wait out a ladder the relay never asked for reads as a hang. buzz-acp has no equivalent of the latter two (no app-backgrounding concept), so parity does not decide them; this is the smallest behavioural change that closes the gap. Gap 5 — NOTICE frames were dropped by `_handleMessage`, so the relay's explicit "slow down" was discarded. Since gaps 3+4+5 compound, the client could not hear the rate limit it was provoking. NOTICE is now logged, and a `rate-limited:` notice arms `_rateLimitDeadlineMs`, a send-side deadline held independently of the reconnect ladder and measured against a monotonic `Stopwatch`: - `_checkRateLimitGate()` mirrors buzz-acp's `check_rate_gate` — returns the remaining duration and lazily clears the field once it expires. - It is consulted before every send. `publish()` returns a failed future rather than transmitting; `sendRaw()` drops the frame, which is right for the ephemeral typing indicators it is documented to carry. - The relay's own `retry in Ns` hint is honoured with no max clamp, mirroring `set_rate_limit_gate` — a relay asking for 60s means 60s. Storing it in the reconnect ladder instead would clamp it to `_maxReconnectDelayMs` (30s). Absent or sub-2s hints floor to 5s, and overlapping notices take the maximum so a later notice cannot shorten a deadline already in place. - Nothing on the reconnect or stability path touches it, so the gate survives both. It is cleared only on expiry and on dispose. A gate rather than a reconnect-ladder bump because a relay that rate-limits without closing the socket never reaches the reconnect path at all. `publish()` failing rather than queueing was chosen for the smallest caller blast radius: it already completes with an error on its 8s `TimeoutException` path, so every call site reaching it already handles a failed publish, and `send_message_provider` removes its optimistic local message and rethrows — a gated send surfaces to the user instead of leaving a message that silently never sends. Queue-and-drain was rejected as it would need a retry buffer and an ordering policy this class does not otherwise have. Relationship to PR block#3053 (open, unmerged): that PR adds a `RelayRateLimitGate` armed by CLOSED frames and gating the read path — `fetchHistory`, subscription replay, and closed-retry. It contains no NOTICE handling, no send-side gating and no jitter, so nothing here is a duplicate of it, but both express the same backpressure concept in the same file. If block#3053 lands first, this gate should be folded into its `RelayRateLimitGate` in a small follow-up: that class takes an injectable clock, which would also close the untested-expiry gap noted below. Keeping them separate for now avoids a hard dependency on an unmerged branch. Tests: 13 new cases in mobile/test/shared/relay/relay_session_test.dart (12 -> 25 in the file), none removed or rewritten from the existing set. Each fix was negative-controlled by reverting only its lib/ change and confirming the matching test fails — jitter neutralised gives a flat 1000ms, the reset-on-connect restored collapses the ladder to 2000 where 4000 is expected, and the gate cases assert on what actually reached the socket, so they fail if the gate is not consulted on the send path. The `sendRaw` case asserts a frame does get through before the notice, so the empty expectation after it cannot pass vacuously. Also covered: a 60s hint is not clamped to 30s, and completing the stability window resets the ladder while preserving the deadline. `Random` is injectable through the constructor (alongside the existing `httpClient` and `socketFactory`) so the jitter assertions are deterministic. Not covered, and a divergence from buzz-acp's own test of the same behaviour: gate expiry. `_rateLimitClock` is a real `Stopwatch` with no injection point, so lazily clearing an expired deadline cannot be exercised without a real wait.

Closes gaps 3, 4, and 5 of the mobile relay client's connection resilience (block#3224). Gap 1 (stall detection) is covered by PR block#3231 and gap 2 (timeouts) needs a transport-specific design decision; neither is touched here. Reconnects now jitter each scheduled delay by ±20%, while keeping the exponential ladder itself deterministic. This follows buzz-acp's jittered_duration and prevents a fleet of mobile clients from reconnecting in lockstep after a relay outage. The automatic reconnect path no longer resets that ladder as soon as a socket authenticates. A 60-second stability timer earns the reset instead, so a connection that repeatedly flaps after a few seconds continues backing off. Caller-driven reconnect() and foreground resume still reset immediately because those paths are explicit user or lifecycle actions and cannot self-spin. Rate-limited NOTICE frames now arm a monotonic deadline independent of the reconnect ladder. The gate: - rejects publish() with RelayRateLimitedException before sending an EVENT; - drops fire-and-forget sendRaw() traffic such as typing indicators; - honours the relay's retry hint without the reconnect ladder's 30-second cap; - floors absent or sub-2-second hints to 5 seconds; - takes the maximum of overlapping deadlines; and - survives reconnect and stability resets, clearing only on expiry or dispose. The gate covers the application send entry points. The separate REQ/CLOSE read-control path remains the scope of PR block#3053, which already gates history, subscription replay, and CLOSED retry but has no NOTICE handling or send-side gate. If block#3053 lands first, this deadline should be folded into its injectable RelayRateLimitGate instead of keeping parallel gate objects. PR block#3406 also edits publish() to wait for a connected relay before sending. If both changes land, the rate-limit check must run before that wait so a send during an active rate-limit window cannot trigger an immediate connection that bypasses the reconnect ladder. Using RelayRateLimitedException rather than a generic StateError keeps that condition distinct from block#3406's background and connection-unavailable errors. Random and monotonic time are injectable for deterministic tests. Fourteen new relay-session cases cover jitter bounds, stability-gated resets, application send blocking, hint floors and overlap, long unclamped hints, deadline preservation, and exact-boundary expiry. Each behavior has a negative control; in particular, making expiry inclusive leaves a zero-duration gate active and fails the new deadline test.

Responding to: a question raised during the team's independent Buzz review of this PR ("Sami Q1"): "HTTP bridge queryRelay not consulting the rate-limit gate (desktop gates both) — fix or justify." Source thread (internal Buzz): buzz://message?channel=ce6ec97e-b85e-4c84-8992-938a40185053&id=ae1ea243a1b115da61e813597c8e0759745c8cd7e0bbe10f8e475faaaa300ba9

Re: `queryRelay` does not consult the rate-limit gate

Investigated. We are making a change here, but not the one suggested, and the reasoning matters because the premise behind the suggestion does not hold.

The premise, corrected

The review reads "desktop gates both paths" as one gate over one shared budget. Desktop actually uses two independent gates:

WebSocket REQs are gated in TypeScript: desktop/src/shared/api/relayGateBoundary.ts:32,75.
The HTTP bridge is gated in Rust, in a separate gate with its own expiry state: desktop/src-tauri/src/relay_admission.rs (activate_rate_limit / wait_for_rate_limit).
The two are only loosely coupled, one-way: a Rust-side 429 arms the TS gate via applyTauriRateLimitIfNeeded (desktop/src/shared/api/tauri.ts:296-301).

Mobile has no equivalent of that second gate at all, which is the actual gap.

The two paths bill to different relay buckets

This is the load-bearing part. A queryRelay call cannot consume the WebSocket budget that the reconnect pacing in this PR is protecting:

Path	Limit type	Window	Default limit
WS `REQ`	`LimitType::WsEvents`	5s	`human_ws_events_per_sec` 10, so 50 per 5s
HTTP `POST /query`	`LimitType::ApiCalls`	60s	`human_api_calls_per_min` 300

WS: crates/buzz-relay/src/admission.rs:9,40-44 and crates/buzz-relay/src/connection.rs:613-623, limit from crates/buzz-auth/src/rate_limit.rs:94-95,116-118.
HTTP: crates/buzz-relay/src/api/bridge.rs:28-36, enforced for /query at bridge.rs:959, limit from crates/buzz-auth/src/rate_limit.rs:91-92,113-115.

They are distinct Redis keys by construction, not by coincidence: rate_limit_key() suffixes the key on LimitType::key_suffix(), which is "ws" versus "api" (crates/buzz-auth/src/rate_limit.rs:71-78,201-208).

Why we rejected making `queryRelay` await the gate

Awaiting the gate on the HTTP path would couple a 300-per-minute bucket to a 50-per-5-seconds bucket. A WebSocket rate-limit stall (up to the gate's 300s cap) would then block unrelated user-visible reads: channel windows (mobile/lib/features/channels/channel_messages_provider.dart:170), mention candidates (mention_candidates_provider.dart:34), thread replies (thread_replies_provider.dart:41), and channel management lookups (channel_management_provider.dart:255,275,332,606). That is a user-visible regression bought for no measured benefit, since the HTTP calls were never spending the WS budget in the first place.

What we did change

The real defect is the opposite direction: mobile never arms the gate from HTTP back-pressure. queryRelay throws RelayException on any non-2xx (mobile/lib/shared/relay/relay_session.dart:177-179), and before this change the only two activate() calls in mobile/lib were both in _handleClosed. The relay does emit a retry hint over HTTP (crates/buzz-relay/src/api/bridge.rs:41-45) and mobile was discarding it.

So a rate-limited HTTP response now arms the shared gate with the relay's retry in Ns hint, matching desktop's deliberate cross-domain back-off intent (desktop/src-tauri/src/relay_admission.rs:13-18), while queryRelay itself stays non-blocking.

Two details worth flagging for anyone reading the diff, both of which would silently defeat a naive version:

The error body is JSON-wrapped, not a bare string: api_error returns {"error": "<msg>"} (crates/buzz-relay/src/api/mod.rs:19-21), so a startsWith("rate-limited:") check on the raw body never matches.
There are two rate-limited shapes, not one: 429 carries rate-limited: quota exceeded; retry in {N}s, and 503 carries rate-limited: shared admission unavailable with no hint (bridge.rs:41-53). Classifying on status code alone misses the 503, so we classify on the message with the existing classifyRelayClosed() and fall back to the gate's 10s default when no hint is present.

Requested change implemented.

Resolves the `relay_session.dart` conflict with the live-subscription recovery work that landed on main as #3053. All four conflict hunks are additive on both sides: the resume clock seam (`now`/`_now`) from this branch and the rate-limit gate, retry timer factory and replay delay from main coexist, and `_dispose()` runs both teardown paths.

### Summary Fixes [this issue](buzz://message?channel=e62570dd-33ad-42c5-b92b-75f2689f9694&id=b726c366abfe62429ee3cdcd34d0c0fb98c33c3ea053480585bed71745412b56): > I often don’t see my bot responses until after I post. they’re usually time stamped correctly so I think it’s just a refresh issue? ### What changed? Buzz Mobile now reconnects relay sessions after the app has remained backgrounded beyond the existing 5-second grace period, even when the session still reports a stale `connected` state. This makes resume recovery independent of whether iOS runs the grace timer before or after delivering `resumed`. Reconnection is now based on elapsed background time rather than a direct socket-health probe. - If the app was backgrounded for at least the 5-second grace period, the socket is presumed dead and the session reconnects regardless of reported status. - If it was backgrounded for less than that, a reported `connected` status is still trusted. In the sub-5-second window the socket is either genuinely alive, which is the common case for a momentary background, or it is dead and the client ping detects it within the two-interval worst case described below. That is now a degraded-latency path, not a silent-forever path. The mobile relay socket now uses `IOWebSocketChannel.connect` with a 30-second `pingInterval`. An unanswered ping closes the Dart socket through the existing disconnect and reconnect path. Detection takes up to two ping intervals, so about 60 seconds worst case, not 30. One interval of idleness elapses and a ping is sent, then a second interval elapses with no pong and the socket closes. Any inbound pong restarts the first stage, so the clock measures idleness rather than running on a fixed cadence. ### Why? Buzz iOS can sometimes stop showing new bot or agent responses after a phone has been locked for 5 to 10 minutes. When the user later posts a message, the missing responses can appear all at once. iOS may suspend Buzz before the short delayed cleanup that would normally close its connection has a chance to run. Before this change, Buzz trusted the resulting stale healthy status on resume and skipped reconnecting, so the missing responses stayed hidden until a later post exposed the dead connection. A state-machine test with a stubbed connection reproduced this reported pattern and showed that it matches this failure mode: the failed post triggered a reconnect that fetched the missing messages. The same test also checked the other candidate explanation, the bug tracked in [#3053](#3053), where the relay has closed the app's subscription. That state does not produce the pattern. Posting succeeds and the user's own message appears, but nothing looks for the missed messages, so they stay hidden. The test confirmed that the missed messages were still available to fetch in that state, so the missing step was a trigger to fetch them. This was not an end-to-end reproduction on an iOS device or a live relay. The new resume check covers the normal lock and unlock path. If the app was backgrounded for less than the 5-second grace period, it still trusts a connection marked as healthy. A dead connection in that window is instead detected by the ping check, which can take up to about 60 seconds but prevents the app from remaining silently stuck. The ping only runs while iOS is running the app, so it does not detect a connection that died during suspension; the resume check owns the lock and unlock path. A pre-existing path also runs the same resume handling when network connectivity returns while the app is already in the foreground. Because the app was not backgrounded, this change does not alter that path, which still trusts a connection marked as healthy and relies on the slower ping check. Recovery from a subscription that the relay explicitly closes remains in [#3053](#3053), and the two changes overlap in one file. Changes to how missed messages are backfilled or replayed are out of scope. ### How is it tested? Full mobile suite at base and head.

…eplay (#129) * feat(relay): add a session rate-limit gate and parse the relay's retry hint Groundwork for recovering a rate-limited subscription instead of dropping it. `RelayRateLimitGate` records that a *connection* is over budget rather than leaving each caller to rediscover it: one refusal slows every request behind it. Windows extend and never shrink, so a second refusal carrying a shorter hint (or none) cannot undercut the first and release everybody early. Clock and sleep are injected, on `ReconnectPolicy`'s principle. `OKReason` gains `retryAfterSeconds`, parsing the relay's canonical `retry in Ns`, and stops treating two `error:` messages as retryable: `too many subscriptions` and `mixed search` are the relay saying the request itself is the problem, and retrying either on a timer is an infinite loop that also keeps the subscription budget full. Ports block/buzz#3053; nothing consumes the gate yet. * feat(relay): retry a refused subscription and pace reconnect replay A retryable `CLOSED` no longer drops the subscription. It stays registered and re-REQs itself under `ReconnectPolicy` backoff, and only when the retries are spent does the sink hear about it. That matters because surfacing it immediately is what made one refused channel cost a full directory refetch plus a re-REQ of every other channel — recovery that is itself a burst. A `rate-limited:` refusal also opens the session gate, so the rest of a reconnect replay waits behind the same window instead of each request rediscovering the budget. The retry delay is the longer of that window and the subscription's own backoff. Reconnect replay now goes out in batches of 8 with a 50ms pause, consulting the gate before each batch rather than once at the top — a refusal during the replay has to slow the batches still to come. Retry state is cleared by a clean EOSE, by a new socket, and on disconnect; the gate is reset on disconnect, since the budget belonged to the connection that refused. `sendRequest` is the single choke point that honours the gate, and it re-checks subscription identity and epoch after the wait, which a long window can stretch to minutes. Deviation from block/buzz#3053: upstream retries indefinitely. Hive stops at `maxClosedRetries` and surfaces, because unlike upstream it has a backstop to fall back to — the engine's directory-refresh recovery. Retrying forever would keep that from ever running. * test(relay): cover the gate, the retry hint, and the refused-subscription path Ten cases: gate windows (default, hint, clamp, extend, never-shrink, reset releasing waiters), hint parsing including a digit-bearing message that is not a rate limit, the two `error:` messages that are now terminal, a rate-limited CLOSED re-REQing rather than surfacing, and a subscription surfacing once its retry budget is spent. Both subscription cases were checked against the negative: with the `.retryable` branch disabled they fail on the missing re-REQ. They wait on a bounded `holds(within:)` rather than the suite's `waitUntil`, which spins forever — `.timeLimit` cannot interrupt a `Task.yield()` loop that never checks cancellation, so a regression there hangs the run instead of failing it. The first negative-control attempt hung for exactly that reason. * fix(relay): keep the rate-limit gate off the registration path `sendRequest` is the one choke point every REQ passes through, which made it the obvious place to honour the gate — and the wrong one. `register(filters:sink:)` awaits it, and the engine registers channels in a serial loop, so a 300-second window would suspend registration for its full length once per channel. Subscribing to a channel would have looked like a hang. The gate stays on the paths that are already background work and already batched: the reconnect replay, per batch, and a refused subscription's retry. A newly registered subscription now sends immediately, and if the relay refuses it for budget, `handleClosed` schedules the retry behind the gate — the same outcome, without stalling the caller to get it. Caught self-reviewing the diff before the device build.

### Summary Fixes [this issue](buzz://message?channel=e62570dd-33ad-42c5-b92b-75f2689f9694&id=b726c366abfe62429ee3cdcd34d0c0fb98c33c3ea053480585bed71745412b56): > I often don’t see my bot responses until after I post. they’re usually time stamped correctly so I think it’s just a refresh issue? ### What changed? Buzz Mobile now reconnects relay sessions after the app has remained backgrounded beyond the existing 5-second grace period, even when the session still reports a stale `connected` state. This makes resume recovery independent of whether iOS runs the grace timer before or after delivering `resumed`. Reconnection is now based on elapsed background time rather than a direct socket-health probe. - If the app was backgrounded for at least the 5-second grace period, the socket is presumed dead and the session reconnects regardless of reported status. - If it was backgrounded for less than that, a reported `connected` status is still trusted. In the sub-5-second window the socket is either genuinely alive, which is the common case for a momentary background, or it is dead and the client ping detects it within the two-interval worst case described below. That is now a degraded-latency path, not a silent-forever path. The mobile relay socket now uses `IOWebSocketChannel.connect` with a 30-second `pingInterval`. An unanswered ping closes the Dart socket through the existing disconnect and reconnect path. Detection takes up to two ping intervals, so about 60 seconds worst case, not 30. One interval of idleness elapses and a ping is sent, then a second interval elapses with no pong and the socket closes. Any inbound pong restarts the first stage, so the clock measures idleness rather than running on a fixed cadence. ### Why? Buzz iOS can sometimes stop showing new bot or agent responses after a phone has been locked for 5 to 10 minutes. When the user later posts a message, the missing responses can appear all at once. iOS may suspend Buzz before the short delayed cleanup that would normally close its connection has a chance to run. Before this change, Buzz trusted the resulting stale healthy status on resume and skipped reconnecting, so the missing responses stayed hidden until a later post exposed the dead connection. A state-machine test with a stubbed connection reproduced this reported pattern and showed that it matches this failure mode: the failed post triggered a reconnect that fetched the missing messages. The same test also checked the other candidate explanation, the bug tracked in [block#3053](block#3053), where the relay has closed the app's subscription. That state does not produce the pattern. Posting succeeds and the user's own message appears, but nothing looks for the missed messages, so they stay hidden. The test confirmed that the missed messages were still available to fetch in that state, so the missing step was a trigger to fetch them. This was not an end-to-end reproduction on an iOS device or a live relay. The new resume check covers the normal lock and unlock path. If the app was backgrounded for less than the 5-second grace period, it still trusts a connection marked as healthy. A dead connection in that window is instead detected by the ping check, which can take up to about 60 seconds but prevents the app from remaining silently stuck. The ping only runs while iOS is running the app, so it does not detect a connection that died during suspension; the resume check owns the lock and unlock path. A pre-existing path also runs the same resume handling when network connectivity returns while the app is already in the foreground. Because the app was not backgrounded, this change does not alter that path, which still trusts a connection marked as healthy and relies on the slower ping check. Recovery from a subscription that the relay explicitly closes remains in [block#3053](block#3053), and the two changes overlap in one file. Changes to how missed messages are backfilled or replayed are out of scope. ### How is it tested? Full mobile suite at base and head.

Per-agent dialogs had structured numeric fields but only for `isBuzzAgentRuntime` — incorrectly excluding Goose. This PR unifies numeric-tuning capability across all surfaces, fixes a pre-existing dual-editor defect, and adds full test coverage. ## What changed ### Phase 1 — Catalog projection - Add `max_rounds_env_var` to `KnownAcpRuntime` in `runtime_metadata.rs` (`Some("BUZZ_AGENT_MAX_ROUNDS")` for buzz-agent, `None` elsewhere). - Project all three numeric env-var fields (`max_tokens_env_var`, `context_limit_env_var`, `max_rounds_env_var`) end-to-end: `AcpRuntimeCatalogEntry` Rust struct, TS `types.ts`, `RawAcpRuntimeCatalogEntry` + `fromRawAcpRuntimeCatalogEntry` in `tauri.ts`, and the e2e mock bridge (`withMockRuntimeConfigMetadata`). ### Phase 2 — Field model - `deriveAgentConfigFieldModel` now derives `maxOutputTokens` / `contextLimit` / `maxRounds` descriptors from catalog-projected fields. - `structuredEnvKeys(descriptors)` — exported helper that takes the **rendered** descriptor set (not the whole model). Hidden keys follow what is actually rendered per surface: global hides effort + all three numeric keys for buzz-agent / two for Goose; per-agent buzz-agent hides effort + three numeric keys; per-agent Goose hides only its two numeric keys. `BUZZ_AGENT_THINKING_EFFORT` stays a visible generic env row per-agent because no effort control renders there. ### Phase 3 — UI - Extract `NumericTuningFields` from `buzzAgentModelTuningFields.tsx` as a shared descriptor-driven component (`descriptors`, `envVars`, `inheritedEnvVars`, `onEnvVarChange`). Kind-specific minima: `NUMERIC_KIND_MIN` map (`maxOutputTokens`/`contextLimit`: 1, `maxRounds`: 0) applied to `<input min>`. - **Global surface** (`AgentConfigFields.tsx`): deduplicate the previously duplicated Advanced env-editor block; render `NumericTuningFields` below the env editor when descriptors exist; `hiddenKeys` and `bakedGenericRows` exclusions use `structuredEnvKeys` so structured keys are never double-rendered. Under 1000 lines. - **Per-agent surfaces** (`EditAgentAdvancedFields`, `PersonaAdvancedFields`): replace `isBuzzAgentRuntime` as the numeric-field gate with `deriveNumericDescriptors(selectedRuntime)` from `agentConfigCore`; hidden keys come from `structuredEnvKeys(numericDescriptors)` — the same rendered descriptor set, no local rebuilding (fixes pre-existing dual-editor defect). Catalog status carried as `RuntimeCatalogStatus` (`loading | ready | error`); both error and loading withhold structured controls and leave saved values visible as generic rows, making error distinguishable from "runtime not capable" (`ready` + no runtime). - **Dialogs** (`AgentDefinitionDialog`, `AgentInstanceEditDialog`, callers): `AgentDefinitionDialog` accepts `runtimeCatalogStatus?: "loading" | "ready" | "error"` (replaces separate `runtimesLoading`/`runtimesError` booleans); all call sites — `AgentManagementDialogs`, `AgentsView`, `RequestedAgentCreateDialogs`, `UserProfilePersonaDialogs` — compute and pass the status. ### Phase 4 — Tests - `buildRecord` exported from `EnvVarsEditor.tsx` as a pure `(nextRows, value, requiredKeys, hiddenKeys) => Record<string, string>` helper for isolation testing. - **17 new node tests** in `agentConfigCore.test.mjs`: `deriveNumericDescriptors` (all three fields, partial, undefined runtime, matches field-model subset); `structuredEnvKeys` per surface including discriminating Goose per-agent effort-key invariant; `NUMERIC_KIND_MIN` values. - **4 new node tests** in `EnvVarsEditor.test.mjs`: hidden tuning key preserved through generic row edits; runtime-switch then generic edit (derives both descriptor sets, asserts new-runtime hidden key survives `buildRecord` via `hiddenKeys` and old-runtime key survives via generic rows); baked numeric key excluded via `filterBakedGenericRows` with `numericTuningPlaceholder` assertion; clearing a structured override — `numericTuningPlaceholder` verifies placeholder text. - **5 new Playwright tests** in `agent-numeric-tuning.spec.ts` (added to smoke project `testMatch`): global numeric fields visible for buzz-agent; global: non-capable runtime hides numeric controls; Goose per-agent shows `Inherit (16384)` after saving global value through the UI; delayed catalog: saved values visible as generic rows while loading then structured controls appear after settle; failed catalog: saved values remain visible as generic rows (never the "unsupported" empty state). ## Result - buzz-agent global defaults: Max output tokens, Context limit, Max rounds as structured inputs with `Inherit (N)` placeholders from baked env. - Goose global defaults: Max output tokens, Context limit as structured inputs. - A Goose global value surfaces as `Inherit (<value>)` in the per-agent Goose edit dialog. - No structured key is editable in two places on any surface; no persisted key has zero editors. - No `runtime.id === "buzz-agent"` comparison decides numeric-field visibility anywhere — capability flows catalog → `AcpRuntimeCatalogEntry` → field model → UI.

Not established: the mechanism and sign of free-running distortion (one rig under-charges ~15%, the other over-charges 2.3×), and the 1080p figure has not been re-measured throttled. - the layer paints only on generation/theme/resize and dismisses on first non-empty active-session output, so the measurable busy cost is a short-lived worst case rather than a persistent PTY paint-path tax ## Follow-ups in this PR These are intentionally subsequent commits after the certified static-banner head, not claims about `98ebc8f90`: 1. close the compositor metrology: remeasure the 1080p point throttled and characterize the opposite-sign free-running rAF distortion, with each measurement regime stated 2. add Tyler's animated honeycomb color waves, gated by `prefers-reduced-motion`, a full 62-theme phase-sweep contrast check, and DPR-2 per-tick performance certification 3. land the already-proven mounted theme-switch regression probe from `RESEARCH/BUZZ_TERM_G3A_PROBE/` 4. bound the slow/hang-shaped G1-c mutant `waitFor` 5. optionally trim the generator to its ink bounding box, reducing the minimum viewport from 70 to 62 columns --------- Signed-off-by: tlongwell-block <[email protected]> Signed-off-by: npub1mprnacetjua2xx3p5eddmhxyk6wv929ymm5py8kd2xfxurxahspqqlgyta <d8473ee32b973aa31a21a65adddcc4b69cc2a8a4dee8121ecd51926e0cddbc02@buzz.block.builderlab.xyz> Signed-off-by: npub1jh9wn95s0472h86ahapupaf7m6kx4v9sx2n0atj2hltcfer8k06s5n3pyf <95cae996907d7cab9f5dbf43c0f53edeac6ab0b032a6feae4abfd784e467b3f5@buzz.block.builderlab.xyz> Signed-off-by: npub17jjz49l9jjmhhk7cac63j8yt9z555n9cw8vk7v5jz4vzw4ppld5qgj57cc <f4a42a97e594b77bdbd8ee35191c8b28a94a4cb871d96f32921558275421fb68@buzz.block.builderlab.xyz> Signed-off-by: npub1qyvc0c5kl4gqv2fd97fsk46tu378sqgy35vc83rvgfwne90sel7s0ed67d <011987e296fd5006292d2f930b574be47c7801048d1983c46c425d3c95f0cffd@buzz.block.builderlab.xyz> Co-authored-by: Dawn (sprout agent) <c6237ef84fa537c78dcee78efd2d4e59f728859c7f194da42ac51ededfa0be05@sprout-oss.stage.blox.sqprod.co> Co-authored-by: npub1t2tgm7d8f995uqvmnm8h88sg3wnpp9a5xysjf6dg3tjmgt3ltulqdp8ehr <5a968df9a7494b4e019b9ecf739e088ba61097b4312124e9a88ae5b42e3f5f3e@buzz.block.builderlab.xyz> Co-authored-by: npub1cc3ha7z055mu0rwwu7806t2wt8mj3pvu0uv5mfp2c50dahaqhczshdalg6 <c6237ef84fa537c78dcee78efd2d4e59f728859c7f194da42ac51ededfa0be05@buzz.block.builderlab.xyz> Co-authored-by: npub17jjz49l9jjmhhk7cac63j8yt9z555n9cw8vk7v5jz4vzw4ppld5qgj57cc <f4a42a97e594b77bdbd8ee35191c8b28a94a4cb871d96f32921558275421fb68@buzz.block.builderlab.xyz> Co-authored-by: npub1jh9wn95s0472h86ahapupaf7m6kx4v9sx2n0atj2hltcfer8k06s5n3pyf <95cae996907d7cab9f5dbf43c0f53edeac6ab0b032a6feae4abfd784e467b3f5@buzz.block.builderlab.xyz> Co-authored-by: npub1mprnacetjua2xx3p5eddmhxyk6wv929ymm5py8kd2xfxurxahspqqlgyta <d8473ee32b973aa31a21a65adddcc4b69cc2a8a4dee8121ecd51926e0cddbc02@buzz.block.builderlab.xyz> Co-authored-by: npub1qyvc0c5kl4gqv2fd97fsk46tu378sqgy35vc83rvgfwne90sel7s0ed67d <011987e296fd5006292d2f930b574be47c7801048d1983c46c425d3c95f0cffd@buzz.block.builderlab.xyz> * Polish mobile inbox and media flows (#4512) ## Summary - make mobile unread state visible with bold channel names, an animated Inbox badge, and swipe-to-toggle Inbox rows - add directional transitions for top-level mobile navigation - let mobile send while media uploads, with cancellable progress UI - normalize iOS and Android video uploads, attach poster frames, and improve native video playback ## Validation - `just mobile-check` - `just mobile-test` - `cargo test -p buzz-media` - Pixel smoke test - iPhone smoke test Desktop background uploads moved to #4522 so the two platforms can be reviewed independently. --------- Signed-off-by: kenny lopez <[email protected]> Signed-off-by: Tom Brow <[email protected]> Co-authored-by: leader <71e9f2c44a6932b6772caaaccda1911d010463c3e2c6c40410b8329956046801@buzz.block.builderlab.xyz> Co-authored-by: Tom Brow <[email protected]> * fix(desktop): stop clipping focus ring on channel intro action cards (#2392) (#4374) ## What Fixes #2392 — the action cards in the empty-channel intro ("Create agent", "Add people") had their `focus-visible` ring clipped by the surrounding scroll container. ## Root cause The cards sit in a `flex ... overflow-x-auto pb-1` row. Setting `overflow-x` (without `overflow-y`) makes the browser compute `overflow-y: auto` as well, so the container clips anything painted outside its padding box — including the cards' `focus-visible:ring-2` box-shadow. With only `pb-1` padding, the top/left/right of the ring were cut off when Tabbing to a card. ## Change `desktop/src/features/messages/ui/ChannelIntroBlock.tsx` — `pb-1` → `p-1` on the action-cards scroll container, reserving 4px on all four sides so the focus ring renders fully inside the scroll container's padding box. - 1 file, 1 line.

Cache emission semantics (D4) Replaces the unconditional `MAY` with qualified obligations: - Publishers SHOULD emit `cacheReadTokens` / `cacheWriteTokens` when the provider exposes a cache component. - Publishers MUST preserve an explicit zero when the provider reports zero. - Publishers MUST omit the field (never null or fabricated zero) when that component is unavailable to the publisher — including when the provider supports it but the harness does not surface it. An explicit carve-out in both the JSON comment block and the Numeric-validity prose exempts these fields from the payload-wide null guidance. Omission is the only valid representation for an unavailable cache component. ### 2. Optional `pricingIdentity` field (D2') Adds an optional, non-nullable `pricingIdentity` object (`authority`, `model`, `cacheClass`), defined as billing authority — distinct from the transport `Provider` enum. - `authority` is a registered billing-namespace identifier: exact lowercase hostname, no scheme, no path, no trailing slash. Registered values: `api.anthropic.com`, `api.openai.com`, `openrouter.ai`. The set extends only by NIP amendment. Pricing lookup is an exact string match on `(authority, model)`. - Present only when the publisher can prove applicability: direct official-endpoint connections prove via the actually-requested resolved model; other routes MUST receive response-supplied authoritative billing identity. - MUST omit for custom/overridden base URLs, gateways (unless the gateway is the named billing authority), unresolved aliases, and turns where usage contributions carry more than one billing identity (including identity-bearing mixed with unresolved). - `cacheClass` is omitted (not null) when not applicable. - `pricingIdentity` is optional but not nullable — omission is the only absence representation. - The existing `model` field retains its non-billing semantics (configured/session model) and is never overloaded. - Consumers MUST treat omission as "price unknown" and MUST NOT infer a price from the session `model` field. ### 3. Consumer cost guidance (D4) - Consumers MAY recompute cost estimates using the billing identity and a pricing manifest. - Consumers MUST retain the provenance of any cost value (e.g. `manifest-estimated`, `wire-reported`). - Consumers MUST NOT merge manifest-estimated and wire-reported costs into an unlabeled total. Manifest-vs-wire display preference is application policy and deliberately excluded from this NIP. ## Scope Doc-only.

When a human mentions work "you" are doing in another channel, the current session can misread this as its own active context and try to coordinate, re-plan, or take ownership of it — causing confusion and wasted turns. ## What changed Added a `## Session Model` section to `crates/buzz-acp/src/base_prompt.md`, inserted immediately after the opening paragraph and before `## Buzz CLI`. The section explains: - Each channel is a separate session; multiple sessions of the same agent identity may be active simultaneously. - Sessions share core memory, workspace, and relay — but not conversation context or in-flight reasoning. - Cross-channel work belongs to the owning session by default; the current session may take it over only when the human explicitly requests it.

On launch, that briefly exposes pubkey-derived labels in place of familiar display names. ## What - Persist a bounded, relay-scoped cache of last-known display names, NIP-01 names, and NIP-05 handles - Seed batch profile queries from those labels immediately, while keeping them stale so the existing relay request revalidates them - Keep cached data presentation-only: avatars and ownership metadata are not persisted or used to seed profile-detail caches - Remove cleared or missing profiles, purge a relay's labels when its community is removed, and include the cache in local-storage quota recovery - Add unit coverage for parsing, bounds, eviction, malformed data, and cleared profiles - Add an E2E regression that delays the relay profile response and verifies the cached name is rendered first ## Risk Assessment Low. The cache is disposable, capped at 1,000 entries per relay, scoped by normalized relay URL, and always revalidated. It contains only public label fields and does not restore avatars, agent ownership, or authorization state. ## Verification - `just ci` - `pnpm typecheck` - `pnpm test` — 3,727 passed - `pnpm exec playwright test tests/e2e/channels.spec.ts --grep "cached profile labels"` — passed Generated with Codex * Polish sidebar unread hierarchy (#4573) ## Summary - Keep selected sidebar rows regular by default; manually unread rows become bold immediately. - Apply a clearer dark-mode hierarchy: standard inactive rows at 75%, muted rows at 45%, and unread rows at full emphasis. - Keep hover text color stable while retaining the selected-row and unread cues. ## Validation - `pnpm typecheck` - `pnpm build:e2e` - Playwright: sidebar badge and channel-mute coverage ## Screenshots Posted in the PR comments. --------- Signed-off-by: kenny lopez <[email protected]> * feat(desktop): surface config diff in restart-required badge (#3637) The "Restart required" badge reports that an agent's running config has drifted from its spawn-time config, but never says what changed. This ships the full feature: a typed Rust diff engine and a TS/UI layer that renders it at every badge site. ## Rust core (spawn-snapshot diff engine) Replaces the lossy `u64` `spawn_config_hash` with a typed `SpawnConfigSnapshot`. The snapshot is stamped from the already-resolved command/env/config values immediately before `spawn()`, closing the race window where a mid-spawn config edit would suppress the badge. `SpawnConfigSnapshot::canonical()` is the single JSON projection shared by the badge and the diff. Drift is `to_value(stamped) != to_value(current)`; the diff is a generic leaf walk over those same two values, so badge-on and diff-non-empty are structurally guaranteed. Adding a snapshot field reaches the UI with no code change to the diff engine — `mutation_table_covers_every_serialized_field` fails CI if a new field arrives without a mutation row. `eligible_restart_diff(persona_orphaned, Option<TrackedSpawnState>)` returns the final vector — snapshot walk entries plus a synthetic `adapter_availability` entry. It returns empty for an orphaned instance (spawning one would fail) and for agents with no tracked spawn state (never stamped, can never have drifted). `needs_restart = !restart_diff.is_empty()` derives from that vector and nothing else. Redaction policy (`policy_for(path)`) is shared by the wire diff and the snapshot's manual `Debug` via `is_safe_to_reveal()` from `managed_agents::env_vars` as the single authority for env-key masking: | Policy | Paths | Rendering | |---|---|---| | `Text` | `system_prompt`, `team_instructions` | character counts only | | `MaskedBare` | `args`, `relay_url` | `••••`, no suffix | | `MaskedSuffix` | non-allowlisted `env.*` | `••••` + last 4 chars when longer than 8 | | `Plain` | allowlisted `env.*` (`BUZZ_AGENT_THINKING_EFFORT`, `BUZZ_AGENT_PROVIDER`, `BUZZ_AGENT_MODEL`, `DATABRICKS_HOST/MODEL`) and everything else | verbatim | Default-deny: every env key not in the explicit allowlist stays masked. `is_safe_to_reveal()` is the single allowlist authority for both the baked-env display and the diff. `restart_diff` is omitted from the wire when empty (`skip_serializing_if`). ## TypeScript / UI layer New `restartDiff.ts` module defines `RestartDiffEntry`, `RestartChange`, `JsonValue`; `tauri.ts` and `types.ts` re-export and add `restart_diff` / `restartDiff` fields (Rust omission → `restartDiff: []`). **`RestartDiffBadge`** — hover tooltip capped at 6 entries + "and N more", `asChild` span trigger (never inside a `<button>`), auto-restart blurb below the diff list (on/off variant from `autoRestartEnabled` prop; same `AUTO_RESTART_ON_BLURB` / `AUTO_RESTART_OFF_BLURB` constants shared with the Runtime-tab banner). **`RestartDiffList`** renders the full uncapped list for the Runtime-tab banner with `tooltip`/`inline` presentation variants for correct foreground in both surfaces. **`ManagedAgentRow` B4 fix** — badge moved to a sibling `div` of the row expansion button; tooltip trigger has no `button` ancestor. **`UnifiedAgentsSection`** — both badge sites render `<RestartDiffBadge>` instead of a raw `<Badge>`, with `autoRestartEnabled` threaded from `agent.autoRestartOnConfigChange`. **Side-panel fix** — `RestartDiffBadge` rendered tab-independently in the `ProfileSummaryView` hero area (was Runtime-tab only — root cause of the ~50% inconsistency Will reported). Hero badge is `self-center` in the flex column. `ProfileRuntimeTabContent` early-return checks `needsRestart` so the banner is never dropped when all other content is empty. Auto-restart blurb in the Runtime-tab banner uses the shared constants. ## Wire shape ```jsonc "restart_diff": [ { "field": "model", "change": { "kind": "value", "before": "gpt-5", "after": "claude-4" } }, { "field": "system_prompt", "change": { "kind": "text", "before_chars": 1234, "after_chars": 1410 } }, { "field": "env.OPENAI_API_KEY", "change": { "kind": "masked", "before": "••••bc12", "after": "••••xyz9" } }, { "field": "env.BUZZ_AGENT_THINKING_EFFORT", "change": { "kind": "value", "before": "medium", "after": "high" } } ] ``` `added`/`removed` occur only for dynamic-map keys; nullable struct fields always serialize as `null`; arrays are atomic leaves (`args`, never `args.0`). ## Tests **Rust** — 1902 passing: snapshot mutation coverage, diff entry serialization, allowlist-aware env masking (`allowlisted_env_key_shows_plain_value`, `allowlisted_env_key_is_case_insensitive`, `non_allowlisted_env_key_stays_masked`), `unstamped_agent_yields_no_badge_and_no_entries` (both orphan values), `summary_without_drift_omits_restart_diff_from_the_wire`, `unstamped_availability_is_not_drift`. Clippy clean, fmt clean. **TypeScript** — `needs-restart-screenshots.spec.ts`: 11 E2E cases registered in the smoke project — all three badge sites, tooltip + keyboard focus, DOM no-button-ancestor assertion, 6+1 truncation, uncapped Runtime list, unknown field humanisation, side-panel badge on default Info tab, inactive/friendly-error Runtime opening path.

The boot catch-up REQ can only fetch events newer than each channel's NIP-RS frontier, so thread replies that arrived before the frontier was passively advanced (the common case) are never re-discovered. Inbox is unaffected because it rebuilds candidates from a relay feed query and checks fine-grained `thread:`/`msg:` markers. The sidebar badge path lacks an equivalent recovery mechanism. ## Solution Persist the sidebar's per-event candidate set to localStorage as a disposable, versioned projection cache (`buzz-observed-unread.v1:<relay>:<pubkey>`) and hydrate it on boot before the catch-up REQ runs. ### New files **`observedUnreadStorage.ts`** — storage module for the cache: - Keyed `buzz-observed-unread.v1:<normalizedRelayUrl>:<normalizedPubkey>` (relay-scoped to prevent cross-community leakage, matching `threadActivityStorage`) - Stores validated per-event `ObservedUnreadEvent` rows; `latestByChannel` is derived at hydration — no divergent dual aggregate - Age pruning (7d = `READ_STATE_HORIZON_SECONDS`), per-channel cap (1000), global cap (5000) across all channels in a scope bucket - Payload `updatedAt` for LRU ordering; registered in `PURE_CACHE_KEY_PREFIXES` for 2 MiB eviction budget - Field-level validation on decode; write failure is non-fatal (session-only degradation) - Snapshot-owning timers: `scheduleObservedUnreadWrite` deep-clones the events map at schedule time — a late A-scope timer can never read B's mutable refs or write under B's key **`useObservedUnreadPersistence.ts`** — hook that owns all persistence lifecycle: - Scope fence: `normalized pubkey + normalized relay` identity; `isScopeLoaded()` callback guards both projection (`rawUnread`) and every **observed-cache mutation** (`recordUnreadEvent`, `removeChannel`, `clearAll`) before touching refs or storage. Note: stale-scope calls to `markChannelRead`/`markAllChannelsRead` can still affect `forcedUnreadRef` and NIP-RS markers, which are pre-existing on `main` and deferred to the NIP-RS arc (see Deferred below). - Synchronous `pagehide` flush closes the Cmd+R timing gap (`useReloadShortcut.ts` reloads within 500ms of teardown, before the 1-second debounce fires) - Identity-reset effect: flushes old scope, resets refs, hydrates from storage, stamps loaded scope — all atomic; cleanup flushes on unmount - `clearAll` cancels the pending timer, resets both in-memory refs, and clears storage in a single transactional operation; `removeChannel` deletes the channel from both refs and replaces any pending snapshot with the current full map — never cancel-without-replacement, preserving sibling-channel events on reload - Marker-prune effect on `readStateVersion`: evaluates each retained event with `observedUnreadEventReadAt()` (the same evaluator used by the projection memo) and removes covered events, rederiving per-channel latest — never clears a whole channel for a single thread/msg marker - Returns a stable `useMemo`-wrapped API object keyed on actual deps so unrelated re-renders do not restart the catch-up REQ - `isScopeLoaded` is a `useCallback` (not a memoized boolean) — always reads the ref at call time, never stale ### Modified files **`useUnreadChannels.ts`** — hook integration: - Calls `useObservedUnreadPersistence` with all persistence wired through the returned API - `rawUnread`: `isScopeLoaded()` guard suppresses A-scope refs from projecting under B - `recordUnreadEvent`: `isScopeLoaded()` fence before touching refs; schedules a debounced write on each successful record - `markChannelRead` clearObserved path: calls `removeChannel` so the cleared state survives reload - `markAllChannelsRead`: delegates to the owner's fenced `clearAll` — the parent does not reset the observed refs directly; `clearAll` owns the transactional clear of both refs and storage, preventing a stale scope-A callback from corrupting scope B **`localStorageQuota.ts`** — registers `buzz-observed-unread.v1:` in `PURE_CACHE_KEY_PREFIXES` ## Design constraints The cache is a **disposable projection**: versioned key, read-through only, safe to delete wholesale. It does not touch `ReadStateManager`, marker semantics, or `forcedUnreadStore`. Zero overlap with the NIP-RS manual mark-read/unread protocol work in progress in another channel; migration path when that lands is "stop reading the key." ## Test coverage **`observedUnreadStorage.test.mjs`** covers storage primitives: - Key normalization, relay-scoped isolation, round-trip correctness - Age-prune and per-channel cap on read and write; global cap across channels - `deriveLatestByChannel` correctness - Thread-marker prune leaves sibling thread events persisted and lit - Scope-isolation state machine: A rows visible in A, absent in B, restored on A again; late A-scope write does not overwrite B's bucket - Malformed structures/fields, relay/pubkey isolation, quota failure degradation **`useObservedUnreadPersistence.test.mjs`** exercises the real hook via `createRoot` + `act`: - pagehide flush: event recorded within debounce window survives reload (headline regression) - Unmount with pending write flushes before teardown - `clearAll` cancels pending debounce so no resurrection after reload - `removeChannel` replaces pending snapshot so sibling channel B survives reload (two-channel repro) - Marker prune: thread and channel markers prune covered events; sibling channels survive - `isScopeLoaded` returns false before identity-reset effect commits, true after - A→B scope switch: pending A-timer is cancelled by flush, A data persisted synchronously (hydration round-trip) - Stale `clearAll` from scope A rejects after scope B loads (observed-cache scope fence) - Stale `removeChannel` from scope A rejects after scope B loads (observed-cache scope fence) - API object identity stable across unrelated re-renders (catch-up stability) **`useUnreadChannels.test.mjs`** exercises the full parent-to-owner seam with real hook mounts: - Stale `markChannelRead` from scope A does not corrupt B's observed bucket after flush - Stale `markAllChannelsRead` from scope A does not overwrite B's bucket after flush ## Deferred Issues deferred to the NIP-RS arc (`#unread-messages-ux`) or future hardening — not regressions introduced by this PR: - **Stale-scope `forcedUnreadRef` / `markContextRead` exposure**: a stale scope-A `markChannelRead` or `markAllChannelsRead` still deletes B's `forcedUnreadRef` entries and advances B's NIP-RS markers via `markContextRead` before the observed-cache fence rejects. This is pre-existing on `origin/main` (identical shape at lines 316/330). Fix requires touching `forcedUnreadStore` and marker paths — out of scope for Fix A. Deferred to the NIP-RS work. - **`isScopeLoaded` empty-scope hardening**: `isScopeLoaded()` returns `true` when `pubkey` and `relay` are empty strings (no active session). A guard could assert non-empty identity before stamping scope-loaded. Low risk in practice since the hook is only mounted after auth, but could be tightened. - **Catch-up batch scheduling**: `handleChannelMessage` and the catch-up loop each clone the full events map per event via `scheduleObservedUnreadWrite`. For channels with large backlogs this produces O(n) snapshot clones per catch-up batch. A batch-schedule API (single snapshot at end of batch) would reduce allocations.

* fix(mobile): recover stale relay sessions (#4372) ### Summary Fixes [this issue](buzz://message?channel=e62570dd-33ad-42c5-b92b-75f2689f9694&id=b726c366abfe62429ee3cdcd34d0c0fb98c33c3ea053480585bed71745412b56): > I often don’t see my bot responses until after I post. they’re usually time stamped correctly so I think it’s just a refresh issue? ### What changed? Buzz Mobile now reconnects relay sessions after the app has remained backgrounded beyond the existing 5-second grace period, even when the session still reports a stale `connected` state. This makes resume recovery independent of whether iOS runs the grace timer before or after delivering `resumed`. Reconnection is now based on elapsed background time rather than a direct socket-health probe. - If the app was backgrounded for at least the 5-second grace period, the socket is presumed dead and the session reconnects regardless of reported status. - If it was backgrounded for less than that, a reported `connected` status is still trusted. In the sub-5-second window the socket is either genuinely alive, which is the common case for a momentary background, or it is dead and the client ping detects it within the two-interval worst case described below. That is now a degraded-latency path, not a silent-forever path. The mobile relay socket now uses `IOWebSocketChannel.connect` with a 30-second `pingInterval`. An unanswered ping closes the Dart socket through the existing disconnect and reconnect path. Detection takes up to two ping intervals, so about 60 seconds worst case, not 30. One interval of idleness elapses and a ping is sent, then a second interval elapses with no pong and the socket closes. Any inbound pong restarts the first stage, so the clock measures idleness rather than running on a fixed cadence. ### Why? Buzz iOS can sometimes stop showing new bot or agent responses after a phone has been locked for 5 to 10 minutes. When the user later posts a message, the missing responses can appear all at once. iOS may suspend Buzz before the short delayed cleanup that would normally close its connection has a chance to run. Before this change, Buzz trusted the resulting stale healthy status on resume and skipped reconnecting, so the missing responses stayed hidden until a later post exposed the dead connection. A state-machine test with a stubbed connection reproduced this reported pattern and showed that it matches this failure mode: the failed post triggered a reconnect that fetched the missing messages. The same test also checked the other candidate explanation, the bug tracked in [#3053](https://github.com/block/buzz/pull/3053), where the relay has closed the app's subscription. That state does not produce the pattern. Posting succeeds and the user's own message appears, but nothing looks for the missed messages, so they stay hidden. The test confirmed that the missed messages were still available to fetch in that state, so the missing step was a trigger to fetch them. This was not an end-to-end reproduction on an iOS device or a live relay. The new resume check covers the normal lock and unlock path. If the app was backgrounded for less than the 5-second grace period, it still trusts a connection marked as healthy. A dead connection in that window is instead detected by the ping check, which can take up to about 60 seconds but prevents the app from remaining silently stuck. The ping only runs while iOS is running the app, so it does not detect a connection that died during suspension; the resume check owns the lock and unlock path. A pre-existing path also runs the same resume handling when network connectivity returns while the app is already in the foreground. Because the app was not backgrounded, this change does not alter that path, which still trusts a connection marked as healthy and relies on the slower ping check. Recovery from a subscription that the relay explicitly closes remains in [#3053](https://github.com/block/buzz/pull/3053), and the two changes overlap in one file. Changes to how missed messages are backfilled or replayed are out of scope. ### How is it tested? Full mobile suite at base and head. Both runs have the same known macOS-host-only failure in `ChannelDetailPage keeps follow mode off while a tall newest message stays visible` at line 1053: - Base: 1,021 passed, 1 skipped, 1 failed - Head: 1,025 passed, 1 skipped, 1 failed Added tests: - [`relay_session_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_session_test.dart): long-background resume reconnect and within-grace control - [`relay_socket_liveness_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_socket_liveness_test.dart): silent-peer disconnect and idle-but-healthy control Mutation checks confirm that removing elapsed-background resume recovery fails with one socket instead of two, and removing `pingInterval` leaves the silent peer connected. Restored production code passes both mutations' regression tests and the healthy idle control.

Per-agent dialogs had structured numeric fields but only for `isBuzzAgentRuntime` — incorrectly excluding Goose. This PR unifies numeric-tuning capability across all surfaces, fixes a pre-existing dual-editor defect, and adds full test coverage. ## What changed ### Phase 1 — Catalog projection - Add `max_rounds_env_var` to `KnownAcpRuntime` in `runtime_metadata.rs` (`Some("BUZZ_AGENT_MAX_ROUNDS")` for buzz-agent, `None` elsewhere). - Project all three numeric env-var fields (`max_tokens_env_var`, `context_limit_env_var`, `max_rounds_env_var`) end-to-end: `AcpRuntimeCatalogEntry` Rust struct, TS `types.ts`, `RawAcpRuntimeCatalogEntry` + `fromRawAcpRuntimeCatalogEntry` in `tauri.ts`, and the e2e mock bridge (`withMockRuntimeConfigMetadata`). ### Phase 2 — Field model - `deriveAgentConfigFieldModel` now derives `maxOutputTokens` / `contextLimit` / `maxRounds` descriptors from catalog-projected fields. - `structuredEnvKeys(descriptors)` — exported helper that takes the **rendered** descriptor set (not the whole model). Hidden keys follow what is actually rendered per surface: global hides effort + all three numeric keys for buzz-agent / two for Goose; per-agent buzz-agent hides effort + three numeric keys; per-agent Goose hides only its two numeric keys. `BUZZ_AGENT_THINKING_EFFORT` stays a visible generic env row per-agent because no effort control renders there. ### Phase 3 — UI - Extract `NumericTuningFields` from `buzzAgentModelTuningFields.tsx` as a shared descriptor-driven component (`descriptors`, `envVars`, `inheritedEnvVars`, `onEnvVarChange`). Kind-specific minima: `NUMERIC_KIND_MIN` map (`maxOutputTokens`/`contextLimit`: 1, `maxRounds`: 0) applied to `<input min>`. - **Global surface** (`AgentConfigFields.tsx`): deduplicate the previously duplicated Advanced env-editor block; render `NumericTuningFields` below the env editor when descriptors exist; `hiddenKeys` and `bakedGenericRows` exclusions use `structuredEnvKeys` so structured keys are never double-rendered. Under 1000 lines. - **Per-agent surfaces** (`EditAgentAdvancedFields`, `PersonaAdvancedFields`): replace `isBuzzAgentRuntime` as the numeric-field gate with `deriveNumericDescriptors(selectedRuntime)` from `agentConfigCore`; hidden keys come from `structuredEnvKeys(numericDescriptors)` — the same rendered descriptor set, no local rebuilding (fixes pre-existing dual-editor defect). Catalog status carried as `RuntimeCatalogStatus` (`loading | ready | error`); both error and loading withhold structured controls and leave saved values visible as generic rows, making error distinguishable from "runtime not capable" (`ready` + no runtime). - **Dialogs** (`AgentDefinitionDialog`, `AgentInstanceEditDialog`, callers): `AgentDefinitionDialog` accepts `runtimeCatalogStatus?: "loading" | "ready" | "error"` (replaces separate `runtimesLoading`/`runtimesError` booleans); all call sites — `AgentManagementDialogs`, `AgentsView`, `RequestedAgentCreateDialogs`, `UserProfilePersonaDialogs` — compute and pass the status. ### Phase 4 — Tests - `buildRecord` exported from `EnvVarsEditor.tsx` as a pure `(nextRows, value, requiredKeys, hiddenKeys) => Record<string, string>` helper for isolation testing. - **17 new node tests** in `agentConfigCore.test.mjs`: `deriveNumericDescriptors` (all three fields, partial, undefined runtime, matches field-model subset); `structuredEnvKeys` per surface including discriminating Goose per-agent effort-key invariant; `NUMERIC_KIND_MIN` values. - **4 new node tests** in `EnvVarsEditor.test.mjs`: hidden tuning key preserved through generic row edits; runtime-switch then generic edit (derives both descriptor sets, asserts new-runtime hidden key survives `buildRecord` via `hiddenKeys` and old-runtime key survives via generic rows); baked numeric key excluded via `filterBakedGenericRows` with `numericTuningPlaceholder` assertion; clearing a structured override — `numericTuningPlaceholder` verifies placeholder text. - **5 new Playwright tests** in `agent-numeric-tuning.spec.ts` (added to smoke project `testMatch`): global numeric fields visible for buzz-agent; global: non-capable runtime hides numeric controls; Goose per-agent shows `Inherit (16384)` after saving global value through the UI; delayed catalog: saved values visible as generic rows while loading then structured controls appear after settle; failed catalog: saved values remain visible as generic rows (never the "unsupported" empty state). ## Result - buzz-agent global defaults: Max output tokens, Context limit, Max rounds as structured inputs with `Inherit (N)` placeholders from baked env. - Goose global defaults: Max output tokens, Context limit as structured inputs. - A Goose global value surfaces as `Inherit (<value>)` in the per-agent Goose edit dialog. - No structured key is editable in two places on any surface; no persisted key has zero editors. - No `runtime.id === "buzz-agent"` comparison decides numeric-field visibility anywhere — capability flows catalog → `AcpRuntimeCatalogEntry` → field model → UI.

The earlier mobile attempt coupled sorting to unsafe dirty-state behavior that could overwrite newer cross-client changes. **Solution:** Add mobile sorting controls and encrypted NIP-78 synchronization using the existing desktop `channel-sort` contract, while retaining ordinary whole-blob last-write-wins behavior. Local state is scoped by identity and normalized relay, startup closes fetch/subscription gaps, and both clients use the same deterministic ordering rules. <details> <summary>File changes</summary> **desktop/src/features/sidebar/lib/channelSortPreference.test.mjs** Updates ordering coverage for the deterministic, cross-client A–Z comparison rule. **desktop/src/features/sidebar/lib/channelSortPreference.ts** Aligns desktop channel-name collation with mobile so synchronized preferences produce the same visible order. **mobile/lib/features/channels/channel_sort/channel_sort_manager.dart** Adds encrypted relay synchronization with safe startup gap handling, clock checks, and ordinary last-write-wins conflicts. **mobile/lib/features/channels/channel_sort/channel_sort_provider.dart** Scopes sort state to the active identity and community lifecycle. **mobile/lib/features/channels/channel_sort/channel_sort_storage.dart** Defines the desktop-compatible payload, relay-scoped cache and migration, cleanup, and shared ordering behavior. **mobile/lib/features/channels/channels_page.dart** Connects sort state to the channel page. **mobile/lib/features/channels/channels_page/body.dart** Applies each selected order to Starred, custom groups, Channels, and DMs. **mobile/lib/features/channels/channels_page/sections.dart** Adds checked Recent and A–Z actions using the existing anchored-popover UI. **mobile/test/features/channels/channel_sort/channel_sort_manager_test.dart** Covers payload adoption, encrypted publication, conflicts, timestamps, retries, and cleanup. **mobile/test/features/channels/channel_sort/channel_sort_storage_test.dart** Covers parsing, relay isolation, migration, cleanup, and ordering modes. **mobile/test/features/channels/channels_page_test.dart** Verifies the group controls expose both choices. </details> ### Reproduction steps 1. Open the mobile channel list with populated built-in and custom groups. 2. Open a group menu and choose **Sort: Recent**; confirm active channels move to the top. 3. Choose **Sort: A–Z**; confirm deterministic alphabetical ordering returns. 4. Repeat for Starred, a custom group, Channels, and DMs. 5. Open desktop with the same identity and community and confirm each synchronized preference. 6. Switch communities and confirm cached preferences do not bleed across relays. ### Screenshots Approved `live` custom-section flow with `research` kept offscreen. | Recent selected | A–Z result | A–Z selected | |---|---|---| | ![live custom section with Recent selected](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/4231/live-recent-selected.png) | ![live custom section sorted A–Z](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/4231/live-az-result.png) | ![live custom section with A–Z selected](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/4231/live-az-selected.png) | ### Validation - Mobile `flutter analyze` — clean - Focused mobile sort and channel-page suites — 37/37 passed - Desktop full suite — 3906/3906 passed - Mobile full suite — 1034 passed, 1 skipped, 1 unrelated baseline failure reproduced at `ac4fa13b8`  --------- Signed-off-by: Taylor Ho <[email protected]> Co-authored-by: npub1223z34hd7vtwc6qj4s7flsxkj644nlre2nthu7lrrmkumhu3xddsrx9r6w <52a228d6edf316ec6812ac3c9fc0d696ab59fc7954d77e7be31eedcddf91335b@buzz.block.builderlab.xyz> * feat: ship Buzz Term (#4347) ## Summary - ship **Buzz Term** end to end: the terminal engine/runtime, mounted desktop substrate, and user-visible naming - add Quinn's tape-deck-inspired banner: a beveled chassis filled by the `buzz term` wordmark, surrounded by a complete-hex field - derive the wordmark's three-stop sweep from each theme's terminal palette so primary, secondary, and accent roles remain visibly distinct across all 62 shipped themes, including light themes - paint the banner once on its own pointer-transparent canvas; PTY rendering beneath it remains unchanged ## Banner behavior - uses the renderer's shared `8.4 × 17` cell metrics and production aspect ratio `2.0238` - regenerates only for viewport/theme changes; palette switches repaint correctly while the banner is visible - dismisses on non-empty output from the active terminal session; empty output and inactive sessions do not dismiss it - fails closed below **70 columns** rather than squeezing or clipping the wordmark - adds **8 lines** to `terminalRenderer.ts` for shared cell metrics and **zero lines inside `paint()`** ## Screenshots | Buzz (light) | Buzz Dark | |---|---| | ![Buzz Term — Buzz light](https://buzz.block.builderlab.xyz/media/fe4c50c1cd03645bff8f3cff588353618fd3004f320ab360165b6cb48f041eb6.png) | ![Buzz Term — Buzz Dark](https://buzz.block.builderlab.xyz/media/e5731f40fe020070c0b327287b4b0b6f0103adde852d0f6451ad66a0ff9d14bb.png) | | Kanagawa Lotus (light) | Red | |---|---| | ![Buzz Term — Kanagawa Lotus](https://buzz.block.builderlab.xyz/media/260b211fe7bd232eb7faa4ec34c99baee5fed380556427c64495ceed3396a8c5.png) | ![Buzz Term — Red](https://buzz.block.builderlab.xyz/media/42a90830824683a0054e24649c58564134af831607736d823992181b792087d3.png) | Additional production-aspect finals: [Vesper](https://buzz.block.builderlab.xyz/media/9ca6514b63f8cfb2107a85ca46f16a940c0883848e6fbc718e411af94aa13100.png), [Min Dark](https://buzz.block.builderlab.xyz/media/f67bd2970e5d64ffb07b1ae78ab58c847e6ebc23e7e7a48e067eb024dba64ec8.png), and [Dark Plus](https://buzz.block.builderlab.xyz/media/290fee08924f37d064abc687ecf3e9526ab05b87e8e56d610f23048949793dbe.png).

The cause of *that* spread is rAF loop rate: the higher figure came from a free-running loop at ~1600fps. Throttled to ~200–236fps, both rigs read 58–68 µs/Mpx (1.25–1.44% of a 60Hz frame). The busy-composite figures quoted above remain the **unthrottled worst case** and are conservative by ~2.3× at the pane. Not established: the mechanism and sign of free-running distortion (one rig under-charges ~15%, the other over-charges 2.3×), and the 1080p figure has not been re-measured throttled. - the layer paints only on generation/theme/resize and dismisses on first non-empty active-session output, so the measurable busy cost is a short-lived worst case rather than a persistent PTY paint-path tax ## Follow-ups in this PR These are intentionally subsequent commits after the certified static-banner head, not claims about `98ebc8f90`: 1. close the compositor metrology: remeasure the 1080p point throttled and characterize the opposite-sign free-running rAF distortion, with each measurement regime stated 2. add Tyler's animated honeycomb color waves, gated by `prefers-reduced-motion`, a full 62-theme phase-sweep contrast check, and DPR-2 per-tick performance certification 3. land the already-proven mounted theme-switch regression probe from `RESEARCH/BUZZ_TERM_G3A_PROBE/` 4. bound the slow/hang-shaped G1-c mutant `waitFor` 5. optionally trim the generator to its ink bounding box, reducing the minimum viewport from 70 to 62 columns --------- Signed-off-by: tlongwell-block <[email protected]> Signed-off-by: npub1mprnacetjua2xx3p5eddmhxyk6wv929ymm5py8kd2xfxurxahspqqlgyta <d8473ee32b973aa31a21a65adddcc4b69cc2a8a4dee8121ecd51926e0cddbc02@buzz.block.builderlab.xyz> Signed-off-by: npub1jh9wn95s0472h86ahapupaf7m6kx4v9sx2n0atj2hltcfer8k06s5n3pyf <95cae996907d7cab9f5dbf43c0f53edeac6ab0b032a6feae4abfd784e467b3f5@buzz.block.builderlab.xyz> Signed-off-by: npub17jjz49l9jjmhhk7cac63j8yt9z555n9cw8vk7v5jz4vzw4ppld5qgj57cc <f4a42a97e594b77bdbd8ee35191c8b28a94a4cb871d96f32921558275421fb68@buzz.block.builderlab.xyz> Signed-off-by: npub1qyvc0c5kl4gqv2fd97fsk46tu378sqgy35vc83rvgfwne90sel7s0ed67d <011987e296fd5006292d2f930b574be47c7801048d1983c46c425d3c95f0cffd@buzz.block.builderlab.xyz> Co-authored-by: Dawn (sprout agent) <c6237ef84fa537c78dcee78efd2d4e59f728859c7f194da42ac51ededfa0be05@sprout-oss.stage.blox.sqprod.co> Co-authored-by: npub1t2tgm7d8f995uqvmnm8h88sg3wnpp9a5xysjf6dg3tjmgt3ltulqdp8ehr <5a968df9a7494b4e019b9ecf739e088ba61097b4312124e9a88ae5b42e3f5f3e@buzz.block.builderlab.xyz> Co-authored-by: npub1cc3ha7z055mu0rwwu7806t2wt8mj3pvu0uv5mfp2c50dahaqhczshdalg6 <c6237ef84fa537c78dcee78efd2d4e59f728859c7f194da42ac51ededfa0be05@buzz.block.builderlab.xyz> Co-authored-by: npub17jjz49l9jjmhhk7cac63j8yt9z555n9cw8vk7v5jz4vzw4ppld5qgj57cc <f4a42a97e594b77bdbd8ee35191c8b28a94a4cb871d96f32921558275421fb68@buzz.block.builderlab.xyz> Co-authored-by: npub1jh9wn95s0472h86ahapupaf7m6kx4v9sx2n0atj2hltcfer8k06s5n3pyf <95cae996907d7cab9f5dbf43c0f53edeac6ab0b032a6feae4abfd784e467b3f5@buzz.block.builderlab.xyz> Co-authored-by: npub1mprnacetjua2xx3p5eddmhxyk6wv929ymm5py8kd2xfxurxahspqqlgyta <d8473ee32b973aa31a21a65adddcc4b69cc2a8a4dee8121ecd51926e0cddbc02@buzz.block.builderlab.xyz> Co-authored-by: npub1qyvc0c5kl4gqv2fd97fsk46tu378sqgy35vc83rvgfwne90sel7s0ed67d <011987e296fd5006292d2f930b574be47c7801048d1983c46c425d3c95f0cffd@buzz.block.builderlab.xyz> * Polish mobile inbox and media flows (#4512) ## Summary - make mobile unread state visible with bold channel names, an animated Inbox badge, and swipe-to-toggle Inbox rows - add directional transitions for top-level mobile navigation - let mobile send while media uploads, with cancellable progress UI - normalize iOS and Android video uploads, attach poster frames, and improve native video playback ## Validation - `just mobile-check` - `just mobile-test` - `cargo test -p buzz-media` - Pixel smoke test - iPhone smoke test Desktop background uploads moved to #4522 so the two platforms can be reviewed independently. --------- Signed-off-by: kenny lopez <[email protected]> Signed-off-by: Tom Brow <[email protected]> Co-authored-by: leader <71e9f2c44a6932b6772caaaccda1911d010463c3e2c6c40410b8329956046801@buzz.block.builderlab.xyz> Co-authored-by: Tom Brow <[email protected]> * fix(desktop): stop clipping focus ring on channel intro action cards (#2392) (#4374) ## What Fixes #2392 — the action cards in the empty-channel intro ("Create agent", "Add people") had their `focus-visible` ring clipped by the surrounding scroll container. ## Root cause The cards sit in a `flex ... overflow-x-auto pb-1` row. Setting `overflow-x` (without `overflow-y`) makes the browser compute `overflow-y: auto` as well, so the container clips anything painted outside its padding box — including the cards' `focus-visible:ring-2` box-shadow. With only `pb-1` padding, the top/left/right of the ring were cut off when Tabbing to a card. ## Change `desktop/src/features/messages/ui/ChannelIntroBlock.tsx` — `pb-1` → `p-1` on the action-cards scroll container, reserving 4px on all four sides so the focus ring renders fully inside the scroll container's padding box. - 1 file, 1 line.

Cache emission semantics (D4) Replaces the unconditional `MAY` with qualified obligations: - Publishers SHOULD emit `cacheReadTokens` / `cacheWriteTokens` when the provider exposes a cache component. - Publishers MUST preserve an explicit zero when the provider reports zero. - Publishers MUST omit the field (never null or fabricated zero) when that component is unavailable to the publisher — including when the provider supports it but the harness does not surface it. An explicit carve-out in both the JSON comment block and the Numeric-validity prose exempts these fields from the payload-wide null guidance. Omission is the only valid representation for an unavailable cache component. ### 2. Optional `pricingIdentity` field (D2') Adds an optional, non-nullable `pricingIdentity` object (`authority`, `model`, `cacheClass`), defined as billing authority — distinct from the transport `Provider` enum. - `authority` is a registered billing-namespace identifier: exact lowercase hostname, no scheme, no path, no trailing slash. Registered values: `api.anthropic.com`, `api.openai.com`, `openrouter.ai`. The set extends only by NIP amendment. Pricing lookup is an exact string match on `(authority, model)`. - Present only when the publisher can prove applicability: direct official-endpoint connections prove via the actually-requested resolved model; other routes MUST receive response-supplied authoritative billing identity. - MUST omit for custom/overridden base URLs, gateways (unless the gateway is the named billing authority), unresolved aliases, and turns where usage contributions carry more than one billing identity (including identity-bearing mixed with unresolved). - `cacheClass` is omitted (not null) when not applicable. - `pricingIdentity` is optional but not nullable — omission is the only absence representation. - The existing `model` field retains its non-billing semantics (configured/session model) and is never overloaded. - Consumers MUST treat omission as "price unknown" and MUST NOT infer a price from the session `model` field. ### 3. Consumer cost guidance (D4) - Consumers MAY recompute cost estimates using the billing identity and a pricing manifest. - Consumers MUST retain the provenance of any cost value (e.g. `manifest-estimated`, `wire-reported`). - Consumers MUST NOT merge manifest-estimated and wire-reported costs into an unlabeled total. Manifest-vs-wire display preference is application policy and deliberately excluded from this NIP. ## Scope Doc-only.

When a human mentions work "you" are doing in another channel, the current session can misread this as its own active context and try to coordinate, re-plan, or take ownership of it — causing confusion and wasted turns. ## What changed Added a `## Session Model` section to `crates/buzz-acp/src/base_prompt.md`, inserted immediately after the opening paragraph and before `## Buzz CLI`. The section explains: - Each channel is a separate session; multiple sessions of the same agent identity may be active simultaneously. - Sessions share core memory, workspace, and relay — but not conversation context or in-flight reasoning. - Cross-channel work belongs to the owning session by default; the current session may take it over only when the human explicitly requests it.

On launch, that briefly exposes pubkey-derived labels in place of familiar display names. ## What - Persist a bounded, relay-scoped cache of last-known display names, NIP-01 names, and NIP-05 handles - Seed batch profile queries from those labels immediately, while keeping them stale so the existing relay request revalidates them - Keep cached data presentation-only: avatars and ownership metadata are not persisted or used to seed profile-detail caches - Remove cleared or missing profiles, purge a relay's labels when its community is removed, and include the cache in local-storage quota recovery - Add unit coverage for parsing, bounds, eviction, malformed data, and cleared profiles - Add an E2E regression that delays the relay profile response and verifies the cached name is rendered first ## Risk Assessment Low. The cache is disposable, capped at 1,000 entries per relay, scoped by normalized relay URL, and always revalidated. It contains only public label fields and does not restore avatars, agent ownership, or authorization state. ## Verification - `just ci` - `pnpm typecheck` - `pnpm test` — 3,727 passed - `pnpm exec playwright test tests/e2e/channels.spec.ts --grep "cached profile labels"` — passed Generated with Codex * Polish sidebar unread hierarchy (#4573) ## Summary - Keep selected sidebar rows regular by default; manually unread rows become bold immediately. - Apply a clearer dark-mode hierarchy: standard inactive rows at 75%, muted rows at 45%, and unread rows at full emphasis. - Keep hover text color stable while retaining the selected-row and unread cues. ## Validation - `pnpm typecheck` - `pnpm build:e2e` - Playwright: sidebar badge and channel-mute coverage ## Screenshots Posted in the PR comments. --------- Signed-off-by: kenny lopez <[email protected]> * feat(desktop): surface config diff in restart-required badge (#3637) The "Restart required" badge reports that an agent's running config has drifted from its spawn-time config, but never says what changed. This ships the full feature: a typed Rust diff engine and a TS/UI layer that renders it at every badge site. ## Rust core (spawn-snapshot diff engine) Replaces the lossy `u64` `spawn_config_hash` with a typed `SpawnConfigSnapshot`. The snapshot is stamped from the already-resolved command/env/config values immediately before `spawn()`, closing the race window where a mid-spawn config edit would suppress the badge. `SpawnConfigSnapshot::canonical()` is the single JSON projection shared by the badge and the diff. Drift is `to_value(stamped) != to_value(current)`; the diff is a generic leaf walk over those same two values, so badge-on and diff-non-empty are structurally guaranteed. Adding a snapshot field reaches the UI with no code change to the diff engine — `mutation_table_covers_every_serialized_field` fails CI if a new field arrives without a mutation row. `eligible_restart_diff(persona_orphaned, Option<TrackedSpawnState>)` returns the final vector — snapshot walk entries plus a synthetic `adapter_availability` entry. It returns empty for an orphaned instance (spawning one would fail) and for agents with no tracked spawn state (never stamped, can never have drifted). `needs_restart = !restart_diff.is_empty()` derives from that vector and nothing else. Redaction policy (`policy_for(path)`) is shared by the wire diff and the snapshot's manual `Debug` via `is_safe_to_reveal()` from `managed_agents::env_vars` as the single authority for env-key masking: | Policy | Paths | Rendering | |---|---|---| | `Text` | `system_prompt`, `team_instructions` | character counts only | | `MaskedBare` | `args`, `relay_url` | `••••`, no suffix | | `MaskedSuffix` | non-allowlisted `env.*` | `••••` + last 4 chars when longer than 8 | | `Plain` | allowlisted `env.*` (`BUZZ_AGENT_THINKING_EFFORT`, `BUZZ_AGENT_PROVIDER`, `BUZZ_AGENT_MODEL`, `DATABRICKS_HOST/MODEL`) and everything else | verbatim | Default-deny: every env key not in the explicit allowlist stays masked. `is_safe_to_reveal()` is the single allowlist authority for both the baked-env display and the diff. `restart_diff` is omitted from the wire when empty (`skip_serializing_if`). ## TypeScript / UI layer New `restartDiff.ts` module defines `RestartDiffEntry`, `RestartChange`, `JsonValue`; `tauri.ts` and `types.ts` re-export and add `restart_diff` / `restartDiff` fields (Rust omission → `restartDiff: []`). **`RestartDiffBadge`** — hover tooltip capped at 6 entries + "and N more", `asChild` span trigger (never inside a `<button>`), auto-restart blurb below the diff list (on/off variant from `autoRestartEnabled` prop; same `AUTO_RESTART_ON_BLURB` / `AUTO_RESTART_OFF_BLURB` constants shared with the Runtime-tab banner). **`RestartDiffList`** renders the full uncapped list for the Runtime-tab banner with `tooltip`/`inline` presentation variants for correct foreground in both surfaces. **`ManagedAgentRow` B4 fix** — badge moved to a sibling `div` of the row expansion button; tooltip trigger has no `button` ancestor. **`UnifiedAgentsSection`** — both badge sites render `<RestartDiffBadge>` instead of a raw `<Badge>`, with `autoRestartEnabled` threaded from `agent.autoRestartOnConfigChange`. **Side-panel fix** — `RestartDiffBadge` rendered tab-independently in the `ProfileSummaryView` hero area (was Runtime-tab only — root cause of the ~50% inconsistency Will reported). Hero badge is `self-center` in the flex column. `ProfileRuntimeTabContent` early-return checks `needsRestart` so the banner is never dropped when all other content is empty. Auto-restart blurb in the Runtime-tab banner uses the shared constants. ## Wire shape ```jsonc "restart_diff": [ { "field": "model", "change": { "kind": "value", "before": "gpt-5", "after": "claude-4" } }, { "field": "system_prompt", "change": { "kind": "text", "before_chars": 1234, "after_chars": 1410 } }, { "field": "env.OPENAI_API_KEY", "change": { "kind": "masked", "before": "••••bc12", "after": "••••xyz9" } }, { "field": "env.BUZZ_AGENT_THINKING_EFFORT", "change": { "kind": "value", "before": "medium", "after": "high" } } ] ``` `added`/`removed` occur only for dynamic-map keys; nullable struct fields always serialize as `null`; arrays are atomic leaves (`args`, never `args.0`). ## Tests **Rust** — 1902 passing: snapshot mutation coverage, diff entry serialization, allowlist-aware env masking (`allowlisted_env_key_shows_plain_value`, `allowlisted_env_key_is_case_insensitive`, `non_allowlisted_env_key_stays_masked`), `unstamped_agent_yields_no_badge_and_no_entries` (both orphan values), `summary_without_drift_omits_restart_diff_from_the_wire`, `unstamped_availability_is_not_drift`. Clippy clean, fmt clean. **TypeScript** — `needs-restart-screenshots.spec.ts`: 11 E2E cases registered in the smoke project — all three badge sites, tooltip + keyboard focus, DOM no-button-ancestor assertion, 6+1 truncation, uncapped Runtime list, unknown field humanisation, side-panel badge on default Info tab, inactive/friendly-error Runtime opening path.

The boot catch-up REQ can only fetch events newer than each channel's NIP-RS frontier, so thread replies that arrived before the frontier was passively advanced (the common case) are never re-discovered. Inbox is unaffected because it rebuilds candidates from a relay feed query and checks fine-grained `thread:`/`msg:` markers. The sidebar badge path lacks an equivalent recovery mechanism. ## Solution Persist the sidebar's per-event candidate set to localStorage as a disposable, versioned projection cache (`buzz-observed-unread.v1:<relay>:<pubkey>`) and hydrate it on boot before the catch-up REQ runs. ### New files **`observedUnreadStorage.ts`** — storage module for the cache: - Keyed `buzz-observed-unread.v1:<normalizedRelayUrl>:<normalizedPubkey>` (relay-scoped to prevent cross-community leakage, matching `threadActivityStorage`) - Stores validated per-event `ObservedUnreadEvent` rows; `latestByChannel` is derived at hydration — no divergent dual aggregate - Age pruning (7d = `READ_STATE_HORIZON_SECONDS`), per-channel cap (1000), global cap (5000) across all channels in a scope bucket - Payload `updatedAt` for LRU ordering; registered in `PURE_CACHE_KEY_PREFIXES` for 2 MiB eviction budget - Field-level validation on decode; write failure is non-fatal (session-only degradation) - Snapshot-owning timers: `scheduleObservedUnreadWrite` deep-clones the events map at schedule time — a late A-scope timer can never read B's mutable refs or write under B's key **`useObservedUnreadPersistence.ts`** — hook that owns all persistence lifecycle: - Scope fence: `normalized pubkey + normalized relay` identity; `isScopeLoaded()` callback guards both projection (`rawUnread`) and every **observed-cache mutation** (`recordUnreadEvent`, `removeChannel`, `clearAll`) before touching refs or storage. Note: stale-scope calls to `markChannelRead`/`markAllChannelsRead` can still affect `forcedUnreadRef` and NIP-RS markers, which are pre-existing on `main` and deferred to the NIP-RS arc (see Deferred below). - Synchronous `pagehide` flush closes the Cmd+R timing gap (`useReloadShortcut.ts` reloads within 500ms of teardown, before the 1-second debounce fires) - Identity-reset effect: flushes old scope, resets refs, hydrates from storage, stamps loaded scope — all atomic; cleanup flushes on unmount - `clearAll` cancels the pending timer, resets both in-memory refs, and clears storage in a single transactional operation; `removeChannel` deletes the channel from both refs and replaces any pending snapshot with the current full map — never cancel-without-replacement, preserving sibling-channel events on reload - Marker-prune effect on `readStateVersion`: evaluates each retained event with `observedUnreadEventReadAt()` (the same evaluator used by the projection memo) and removes covered events, rederiving per-channel latest — never clears a whole channel for a single thread/msg marker - Returns a stable `useMemo`-wrapped API object keyed on actual deps so unrelated re-renders do not restart the catch-up REQ - `isScopeLoaded` is a `useCallback` (not a memoized boolean) — always reads the ref at call time, never stale ### Modified files **`useUnreadChannels.ts`** — hook integration: - Calls `useObservedUnreadPersistence` with all persistence wired through the returned API - `rawUnread`: `isScopeLoaded()` guard suppresses A-scope refs from projecting under B - `recordUnreadEvent`: `isScopeLoaded()` fence before touching refs; schedules a debounced write on each successful record - `markChannelRead` clearObserved path: calls `removeChannel` so the cleared state survives reload - `markAllChannelsRead`: delegates to the owner's fenced `clearAll` — the parent does not reset the observed refs directly; `clearAll` owns the transactional clear of both refs and storage, preventing a stale scope-A callback from corrupting scope B **`localStorageQuota.ts`** — registers `buzz-observed-unread.v1:` in `PURE_CACHE_KEY_PREFIXES` ## Design constraints The cache is a **disposable projection**: versioned key, read-through only, safe to delete wholesale. It does not touch `ReadStateManager`, marker semantics, or `forcedUnreadStore`. Zero overlap with the NIP-RS manual mark-read/unread protocol work in progress in another channel; migration path when that lands is "stop reading the key." ## Test coverage **`observedUnreadStorage.test.mjs`** covers storage primitives: - Key normalization, relay-scoped isolation, round-trip correctness - Age-prune and per-channel cap on read and write; global cap across channels - `deriveLatestByChannel` correctness - Thread-marker prune leaves sibling thread events persisted and lit - Scope-isolation state machine: A rows visible in A, absent in B, restored on A again; late A-scope write does not overwrite B's bucket - Malformed structures/fields, relay/pubkey isolation, quota failure degradation **`useObservedUnreadPersistence.test.mjs`** exercises the real hook via `createRoot` + `act`: - pagehide flush: event recorded within debounce window survives reload (headline regression) - Unmount with pending write flushes before teardown - `clearAll` cancels pending debounce so no resurrection after reload - `removeChannel` replaces pending snapshot so sibling channel B survives reload (two-channel repro) - Marker prune: thread and channel markers prune covered events; sibling channels survive - `isScopeLoaded` returns false before identity-reset effect commits, true after - A→B scope switch: pending A-timer is cancelled by flush, A data persisted synchronously (hydration round-trip) - Stale `clearAll` from scope A rejects after scope B loads (observed-cache scope fence) - Stale `removeChannel` from scope A rejects after scope B loads (observed-cache scope fence) - API object identity stable across unrelated re-renders (catch-up stability) **`useUnreadChannels.test.mjs`** exercises the full parent-to-owner seam with real hook mounts: - Stale `markChannelRead` from scope A does not corrupt B's observed bucket after flush - Stale `markAllChannelsRead` from scope A does not overwrite B's bucket after flush ## Deferred Issues deferred to the NIP-RS arc (`#unread-messages-ux`) or future hardening — not regressions introduced by this PR: - **Stale-scope `forcedUnreadRef` / `markContextRead` exposure**: a stale scope-A `markChannelRead` or `markAllChannelsRead` still deletes B's `forcedUnreadRef` entries and advances B's NIP-RS markers via `markContextRead` before the observed-cache fence rejects. This is pre-existing on `origin/main` (identical shape at lines 316/330). Fix requires touching `forcedUnreadStore` and marker paths — out of scope for Fix A. Deferred to the NIP-RS work. - **`isScopeLoaded` empty-scope hardening**: `isScopeLoaded()` returns `true` when `pubkey` and `relay` are empty strings (no active session). A guard could assert non-empty identity before stamping scope-loaded. Low risk in practice since the hook is only mounted after auth, but could be tightened. - **Catch-up batch scheduling**: `handleChannelMessage` and the catch-up loop each clone the full events map per event via `scheduleObservedUnreadWrite`. For channels with large backlogs this produces O(n) snapshot clones per catch-up batch. A batch-schedule API (single snapshot at end of batch) would reduce allocations. Not observable in normal use; deferred as a performance optimization. --------- Signed-off-by: Will Pfleger <[email protected]> Signed-off-by: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> * Refine community invite links (#4734) ## Summary - Separate direct invites from link sharing with a labeled divider. - Show the generated invite URL inline with truncation and a copy control. - Use shared loading feedback and a restrained copy-status resize. ## Validation - `pnpm -C desktop exec playwright test tests/e2e/invite-link-copy.spec.ts tests/e2e/invites-settings-screenshots.spec.ts` (7 passed) --------- Signed-off-by: kenny lopez <[email protected]> * fix(agents): canonicalize stale persona harness…

Resolves the `relay_session.dart` conflict with the live-subscription recovery work that landed on main as block#3053. All four conflict hunks are additive on both sides: the resume clock seam (`now`/`_now`) from this branch and the rate-limit gate, retry timer factory and replay delay from main coexist, and `_dispose()` runs both teardown paths.

### What changed? Mobile now recovers live subscriptions after retryable or rate-limited relay `CLOSED` responses. It ports the existing desktop model: classify terminal versus retryable closures, honor retry hints through a session-owned rate-limit gate, retry with bounded backoff, and replay visible-channel subscriptions first in bounded batches. Channel refreshes also retain unchanged live subscriptions instead of clearing and recreating them. This is desktop parity, not a new relay policy. ### Why? On reconnect or resume, mobile replayed its retained live subscriptions while `channelsProvider` independently cleared and recreated roughly the same set, alongside unread catch-up and open-channel requests. The relay allows 50 REQs per 5 seconds, so users in many channels could predictably exceed the budget. In live reproduction, 55 subscriptions produced 9 rate-limit closures, 60 produced 18, and 80 produced 36. Mobile then treated every live `CLOSED` as terminal, removed the affected subscription, and never restored it. Channel updates could remain dead until a later session reconstruction. This is the primary causal chain behind [BOT-1449](https://linear.app/squareup/issue/BOT-1449/buzz-mobile-posted-messages-dont-appear-until-leavingre-entering-the). Desktop already handles this as normal transient pressure by classifying closures, gating and backing off retries, pacing reconnect replay, and retaining unchanged subscriptions. This change brings mobile to the same recovery model while removing the avoidable request burst. ### How is it tested? Full mobile suite: 721 passed, 1 skipped. Analyzer and formatting checks pass. Required CI checks pass. Added and updated tests cover `CLOSED` classification, retry hints, rate-limit gating, bounded retry and reset behavior, terminal failures, timer cleanup, history gating, visible-first batched replay, and retention of unchanged subscriptions. --------- Signed-off-by: Tom Brow <[email protected]> Co-authored-by: npub1tquskdu6yc4h8l7xxtceculxw600grekeq0xg2ukqfrwl7vrzg3quz3gmp <58390b379a262b73ffc632f19c73e6769ef40f36c81e642b960246eff9831222@buzz.block.builderlab.xyz> Co-authored-by: Codex <[email protected]> Co-authored-by: npub1tu6ed4gf70jg7pvk8uhttlprexznhzpg74am2d3seqd3ececzgusy8hzac <5f3596d509f3e48f05963f2eb5fc23c9853b8828f57bb53630c81b1ce3381239@buzz.block.builderlab.xyz> Co-authored-by: npub1w85l93z2dyetvaev42kvmgv3r5qsgc7rutrvgpqshqefj4sydqqskwstfm <71e9f2c44a6932b6772caaaccda1911d010463c3e2c6c40410b8329956046801@buzz.block.builderlab.xyz>

Buzz Mobile now reconnects relay sessions after the app has remained backgrounded beyond the existing 5-second grace period, even when the session still reports a stale `connected` state. This makes resume recovery independent of whether iOS runs the grace timer before or after delivering `resumed`. Reconnection is now based on elapsed background time rather than a direct socket-health probe. - If the app was backgrounded for at least the 5-second grace period, the socket is presumed dead and the session reconnects regardless of reported status. - If it was backgrounded for less than that, a reported `connected` status is still trusted. In the sub-5-second window the socket is either genuinely alive, which is the common case for a momentary background, or it is dead and the client ping detects it within the two-interval worst case described below. That is now a degraded-latency path, not a silent-forever path. The mobile relay socket now uses `IOWebSocketChannel.connect` with a 30-second `pingInterval`. An unanswered ping closes the Dart socket through the existing disconnect and reconnect path. Detection takes up to two ping intervals, so about 60 seconds worst case, not 30. One interval of idleness elapses and a ping is sent, then a second interval elapses with no pong and the socket closes. Any inbound pong restarts the first stage, so the clock measures idleness rather than running on a fixed cadence. ### Why? Buzz iOS can sometimes stop showing new bot or agent responses after a phone has been locked for 5 to 10 minutes. When the user later posts a message, the missing responses can appear all at once. iOS may suspend Buzz before the short delayed cleanup that would normally close its connection has a chance to run. Before this change, Buzz trusted the resulting stale healthy status on resume and skipped reconnecting, so the missing responses stayed hidden until a later post exposed the dead connection. A state-machine test with a stubbed connection reproduced this reported pattern and showed that it matches this failure mode: the failed post triggered a reconnect that fetched the missing messages. The same test also checked the other candidate explanation, the bug tracked in [block#3053](block#3053), where the relay has closed the app's subscription. That state does not produce the pattern. Posting succeeds and the user's own message appears, but nothing looks for the missed messages, so they stay hidden. The test confirmed that the missed messages were still available to fetch in that state, so the missing step was a trigger to fetch them. This was not an end-to-end reproduction on an iOS device or a live relay. The new resume check covers the normal lock and unlock path. If the app was backgrounded for less than the 5-second grace period, it still trusts a connection marked as healthy. A dead connection in that window is instead detected by the ping check, which can take up to about 60 seconds but prevents the app from remaining silently stuck. The ping only runs while iOS is running the app, so it does not detect a connection that died during suspension; the resume check owns the lock and unlock path. A pre-existing path also runs the same resume handling when network connectivity returns while the app is already in the foreground. Because the app was not backgrounded, this change does not alter that path, which still trusts a connection marked as healthy and relies on the slower ping check. Recovery from a subscription that the relay explicitly closes remains in [block#3053](block#3053), and the two changes overlap in one file. Changes to how missed messages are backfilled or replayed are out of scope. ### How is it tested? Full mobile suite at base and head. Both runs have the same known macOS-host-only failure in `ChannelDetailPage keeps follow mode off while a tall newest message stays visible` at line 1053: - Base: 1,021 passed, 1 skipped, 1 failed - Head: 1,025 passed, 1 skipped, 1 failed Added tests: - [`relay_session_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_session_test.dart): long-background resume reconnect and within-grace control - [`relay_socket_liveness_test.dart`](https://github.com/block/buzz/tree/main/mobile/test/shared/relay/relay_socket_liveness_test.dart): silent-peer disconnect and idle-but-healthy control Mutation checks confirm that removing elapsed-background resume recovery fails with one socket instead of two, and removing `pingInterval` leaves the silent peer connected.

## Summary - refetch mounted mobile thread replies after relay reconnect, preserving the previous reply list during recovery - auto-dispose route-scoped relay reply caches so reopening a thread queries current relay state - invalidate live replies through both the channel-window and legacy websocket-history paths - preserve optimistic-reply confirmation when the route closes before its deferred cleanup - stabilize rapid same-second messages using desktop's existing split contract: channel timelines render `(created_at ASC, id DESC)` while threads render `(created_at ASC, id ASC)` - retain late live rows after a channel window is exhausted instead of dropping same-second tail messages Closes #4404. Closes #4830. Closes #6204. ## Context The broad all-channel/all-DM stale-session defect reported in #4402 is already addressed on current `main` by #4372 and #3053. Two distinct mobile gaps remained: 1. `threadRepliesProvider` was a process-lifetime one-shot query, so replies missed while the socket was stale remained absent after reconnect or after closing and reopening the thread. 2. Mobile had inconsistent timestamp-only and event-id ordering across channel producers. Rapid messages routinely share Nostr's one-second timestamp, so later hydration/live reconciliation could reshuffle them. Desktop deliberately has two render contracts: channel windows reverse the relay's composite order to `(created_at ASC, id DESC)`, while thread replies use `(created_at ASC, id ASC)`. This consolidates the current-main portions of #4831 and #3243 rather than reviving stale overlapping branches. ## Validation Exact pushed head: `be92d9542c6cd1342733bdc5e8359664b511ce02` - focused channel-provider/window/thread suites: 48/48 passed - incident regression: a mounted thread misses a reply while disconnected, reconnects, and renders the recovered reply - route regression: closing and reopening a thread performs a fresh authoritative query - websocket fallback regression: live reply invalidates the mounted thread even without the channel-window path - disposal regression: optimistic confirmation survives provider disposal between rebuild and deferred cleanup - ordering regressions: channel window/live, websocket fallback, optimistic sends, deep links, both pagination paths, and thread merges preserve their desktop-compatible same-second order - boundary regression: exhausted windows admit late same-second live rows without weakening open-page cursor boundaries - independent adversarial review: no production blocker; source contract verified across all producers and relay cursor semantics unchanged - pre-push Mobile lane passed at exact head, including analysis, file-size/branch checks, and full Flutter suite: 1,675/1,675 passed - `git diff --check` --------- Signed-off-by: Wes <[email protected]> Co-authored-by: Carl <32a2e2c9d428ee08902cab75d956da2c1d235a22d4766b0dd4138bf6e2e5db1d@buzz.block.builderlab.xyz>
