Problem

An environment can stop updating in one client while its socket still accepts commands. A durable subscription that fails alone is never restarted, leaving sidebar rows and thread state stale until the client reloads. A controlled malformed shell-stream frame reproduces this on current main: an unsettle command succeeds while the sidebar keeps the thread settled.

Change

Resubscribe durable streams on the same session after an RPC transport failure or a stream decoder SchemaError. Reuse the existing exponential retry delay, capped at 30 seconds, and cancel pending retries when the session changes. Shell and thread subscriptions start at their existing 250 ms delay; other subscriptions default to one second. Finite Find searches retain their prior failure handling instead of automatically resubscribing. Durable transport/decoder retries use a separate counter that resets on session replacement, so valid metadata preceding another bad chunk cannot keep retries at the minimum delay. Isolated stream failures on one long-lived session accumulate toward the 30-second cap. Existing defect observers and domain-error handling remain in place.

Scope and approval

Fixes #4589
GitCafe: #4589

Triaged bug via the automated issue flow. This fixes subscription recovery in the shared client runtime without adding settings, persisted state, contracts, or provider behavior.

Verification

  • Focused RPC client and runtime suites: 35/35 passed. Transport/decoder recovery tests fail with the base implementation. Two additional red tests reproduce finite-search decoder errors being swallowed and valid-first-value failures resetting the backoff; both pass with the fix. Tests also cover growth through the 30-second cap and reset/cancellation on session replacement.
  • Client-runtime typecheck: no errors. Changed-file lint: no new findings; existing polling-loop warnings remain. Formatting and diff whitespace checks pass.
  • Real app on Linux in Chrome: injected a malformed shell frame, observed a new subscription on the same open socket, and saw the accepted unsettle command update the sidebar without reload. Normal settling and full socket reconnect also work. The fault is controlled injection through the real decoder; the original incident's natural trigger is not established.

Integration: merged current main 6e79211743 into head 9446bbefd1. All three changed files are byte-identical to reviewed/captured 86f313103d. Both fresh isolated reviewers returned MERGE; the new F1/B1 evidence audit returned SUFFICIENT. Historical V1–V6 remain evidence at their original SHAs, not execution at current HEAD. The lead independently verified Find failure and explicit Retry on the same OPEN socket. The final auditor independently rebuilt it too: the Search failed/Retry region matched exactly; 734 pixels elsewhere differed in elapsed-age/focus styling, so whole-image rebuild equality is not claimed.

What else changed: the intended differences are sidebar group/count, selected-thread synchronization status, and resumed terminal output. Amplified comparisons also show small wordmark and sidebar-edge raster differences between browser profiles; these are capture differences outside the fix. The index documents every row and supersedes the initial faulty RGBA stability metadata.

F1 — finite Find failure, manual Retry, completion and close/reopen

Normal control query normal-control completed with zero matches on both builds. Then fault-query was entered with receive interception armed. Two immediate query subscriptions appeared on each build; the active one is BEFORE request 87 / AFTER 76. Both initial real Chunk reads were intercepted. BEFORE automatically replaced request 87 with 89, 90 and 91, and stayed Searching. AFTER displayed Search failed / Retry and made no later automatic replacement for about 9.7 seconds. Its socket stayed OPEN. Injection was disarmed before clicking Retry; fresh request 78 completed with zero matches, then Close find → Ctrl+F → query completed again. BEFORE was disarmed and recovered through close/reopen.

Narration / video times: BEFORE normal query 00:36.3, fault query 00:41.9, retries 00:42.9 / 00:45.0 / 00:49.0, close/reopen query 00:57.3. AFTER normal query 00:20.1, fault query 00:25.7, manual Retry 00:35.7, close/reopen query 00:41.6. Initial idle footage includes a locator retry; it is not an app search delay.

What else changed: 684 RGB-different pixels (552 with any channel >16), all inside exported rectangle [1115,61,1195,85): Searching is replaced by the wrapped Search failed label and Retry control. No other pixels differ. Both independently repeated error endpoints are exact RGB matches, separated by 6,000ms BEFORE and 5,944ms AFTER: BEFORE duplicate / AFTER duplicate.

Completed zero-match close/reopen endpoints (pixel-identical across builds):

BEFORE completed control AFTER completed control
BEFORE: completed zero-match search after close/reopen AFTER: completed zero-match search after manual retry and close/reopen

B1 — repeated shell faults, healthy gap, cap and session replacement

Each fault targeted the current orchestration.subscribeShell request after genuine snapshot/synchronized values. The first nine retries stayed on BEFORE socket 5 and AFTER socket 4. A 3s healthy gap after retry 2 included successful unsettle/settle commands and real shell updates; the next AFTER delay remained 1s. Transcript timing measures fault → replacement Request, not request → request. Browser scheduling tolerance is visible in measured values.

Narration / video times: use the fault→replacement times below. Each recovery sends a real settle/unsettle command with successful receipt and visible sidebar/composer change. After the ninth recovery, a tenth fault is injected; only the app socket is closed 1s later. BEFORE has already retried at base delay, while AFTER has a pending capped retry. The new socket receives valid shell values, is faulted once, and returns to base delay. Both are observed past the old fault +32s, followed by successful normal unsettle → settle → unsettle. At about 02:24 both receive an additional matched settle/unsettle for final stills. Long static waits remain in the recording; the transcript is the primary timing evidence.

Recordings: BEFORE recording · AFTER recording.

All accepted-retake dispatch receipts succeeded (21 BEFORE / 25 AFTER, including app-generated receipts); no failed command is part of this retake. Eleven faults per build have genuine first values recorded before injection. Vite sockets were never closed.

Narration for the endpoint pair: final normal recovery is complete and both clients show the same unsettled empty stopped thread. Static stills prove matching presentation and recovery, not retry timing.

What else changed: zero pixels across the retained final before/after endpoints. Both independent duplicate pairs are exact RGB matches, separated by 18,021ms BEFORE / 18,009ms AFTER: BEFORE duplicate / AFTER duplicate. An earlier pair had a fluctuating one-pixel sidebar edge (maximum channel delta 2) and was discarded; it was not accepted using a threshold or masked. Retained timestamp metadata · RGB report.

… after transport error

A durable subscription whose stream fails with an RpcClientError on a
still-healthy session drains forever and never asks the supervisor for a
replacement session. This test is expected to fail until that is fixed.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…y session

A durable subscription whose stream ended with a transport RpcClientError
drained forever, and one whose chunk failed to decode (RpcClient dies with
a SchemaError) failed the whole subscription. Both end only that stream
while the socket stays open, so the supervisor never replaces the session
and, for example, the shell stopped updating until reload.

Both now resubscribe to the same session with the existing bounded
exponential backoff. A replaced session still interrupts the pending retry
through switchMap.

Confirmed: shell and thread subscriptions retain their existing 250 ms retry delay; subscriptions without an override use the new one-second fallback. This restores delivery after an individual stream fails while its session remains healthy. The human-approval routing remains intact; no implementation change was made for this approvability note.

Walkthrough

The RPC client now retries selected durable stream failures on the current session with capped exponential backoff. Search-thread streams retain different transport-failure handling. Tests cover retry timing, session replacement, and decode defects.

Changes: Durable stream retry behavior

Layer / File(s) Summary
Same-session retry handling
packages/client-runtime/src/rpc/client.ts
The client retries non-search subscriptions after transport failures or schema decode defects. Retry delays increase exponentially and cap at 30 seconds. Configured expected-failure retries use the shared helper and retain their configured delay. Search-thread streams wait for a new session after transport failure and do not restart on the same session after these failure types.
Retry and decode-failure tests
packages/client-runtime/src/rpc/client.test.ts, packages/client-runtime/src/state/runtime.test.ts
Tests cover same-session resubscription, retry backoff, and reset after session replacement. Runtime tests verify that a decode defect reaches the consumer and that the failed finite subscription is not recreated.

Explanation

The description includes the required Problem, Change, Scope and approval, and Verification sections. It explains the failure, implementation, linked issue, focused tests, manual verification, limitations, and unverified environments.

Full details: Linked Issues check

Explanation

Issue #4589 requires recovery when an environment subscription stops while the session remains healthy. packages/client-runtime/src/rpc/client.ts now retries durable streams after transport failures and stream SchemaError defects. The retry delay grows exponentially to 30 seconds, resets on session replacement, and pending retries are canceled with the old session. searchThreadStream retains finite-search failure handling. Focused tests cover same-session recovery, decoder failures, backoff growth, session reset, cancellation, and preserved search defects. These changes address the stale-thread behavior without requiring a client restart.

Full details: Out of Scope Changes check

Explanation

The changes are limited to shared client-runtime subscription handling and focused regression tests in client.test.ts and runtime.test.ts. The tests verify issue #4589 recovery and preserve finite-search and domain-error behavior. The diff does not add settings, persisted state, contracts, provider behavior, or unrelated product changes.

Restrict same-session retry to durable subscriptions.

subscribeDynamicMapped applies this retry branch to every EnvironmentSubscriptionRpcTag. threadFindProgressive consumes the finite searchThreadStream and completes only after receiving a result where complete !== false. A persistent transport or decode failure instead enters the retry loop, so the finite search can remain pending indefinitely instead of failing.

Make same-session retry opt-in for durable subscriptions, and exclude searchThreadStream.

Keep backoff across repeated failures after the first value.

subscribeToSession() applies Stream.onFirst to every resubscribed stream. If a stream emits one value and then fails, the callback resets expectedFailureRetries before retryAfter handles the failure. Each attempt therefore uses the base delay instead of backing off toward 30 seconds. Reset the counter only after a sustained healthy period, or track consecutive failures separately.

…m backoff

Two regressions from resubscribing durable streams on a healthy session:

- A finite searchThreadStream subscription whose chunk fails to decode now
  resubscribes on the same session instead of failing its consumer, so the
  progressive thread find never settles. Before that change the SchemaError
  defect reached the atom.
- A shell-like stream that emits a valid value (metadata) and then fails to
  decode on every attempt retries every 250ms forever, because the first
  value resets the retry counter. Delays should grow to the 30s cap on one
  session and restart from the base delay on a replacement session.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ble streams

searchThreadStream is a finite subscription, so it no longer resubscribes on
the same session: a transport failure waits for the next session again and a
chunk decode defect reaches its consumer, as before same-session recovery.

Same-session transport and decode retries now use their own per-session
counter. A first valid value no longer resets it, so a stream that emits and
then fails every time backs off to the 30s cap instead of retrying every
base delay. A replacement session starts a fresh counter. Expected domain
failures keep their counter and its reset on the first value.

Both findings are fixed in 86f313103d, integrated with current main at 9446bbefd1.

  • Finite searchThreadStream keeps its previous decoder-defect propagation and transport handling. The real runtime atom regression test now surfaces the error without resubscribing. Browser proof shows Search failed, no automatic retry, then explicit Retry completing on the same OPEN socket.
  • Durable transport/decoder failures use a separate per-session retry counter. Valid first values still reset the existing domain-error counter, but cannot reset the stream-failure counter. The clock regression and real-app recording prove 250→500→1k→2k→4k→8k→16k→30k→30k ms, session replacement returning to 250ms, and cancellation of the prior session's pending retry.

Post-integration focused tests: 35/35; client-runtime typecheck: no errors. Both fresh isolated reviewers returned MERGE and the new evidence audit returned SUFFICIENT. Macroscope's human-approval routing remains intact.
