Automated backport of #2204 to stable (backport job run).

AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.

Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204

The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.

Byte-identical to original

  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts

Stable-shape adaptations

The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:

  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors

Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.

Correctly omits

The original PR #2204 had 3 commits:

  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"

So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.

Verified locally

  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:
    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓

CI

  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.

Behavior summary

Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).

Faithful backport. Approving.

Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Revert "fix(core): propagate exhausted transient world errors to the queue"
This reverts commit 7bb62e9.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Revert "fix(core): propagate exhausted transient world errors to the queue"
This reverts commit 7bb62e9.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Revert "fix(core): propagate exhausted transient world errors to the queue"
This reverts commit 7bb62e9.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Revert "fix(core): propagate exhausted transient world errors to the queue"
This reverts commit 7bb62e9.

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Revert "fix(core): propagate exhausted transient world errors to the queue"
This reverts commit 7bb62e9.

Automated backport of #2204 to stable (backport job run).
AI recommendation: This is a self-contained bug fix in @workflow/world-vercel that retries transient response-body parse failures on idempotent requests, with accompanying tests. Both modified files exist on stable, the fix doesn't depend on any main-only APIs (the paired core change was reverted within this PR), and it addresses a real production issue (events.list PARSE_ERROR) that likely also affects stable.
Merge conflicts were resolved by AI (opencode with anthropic/claude-opus-4.7). Please review the conflict resolution carefully before merging.

[world-vercel] Retry transient response-body parse failures in the HT…
9b667d1
…TP client (#2204)
* fix(world-vercel): retry transient response-body parse failures in the HTTP client
A sporadic failure reading/decoding a 2xx response body (truncated or
terminated stream, connection reset mid-body, or a gateway returning a
non-CBOR/JSON body) was surfaced immediately as a PARSE_ERROR. The
shared RetryAgent only retries connection/5xx failures — body
consumption happens after it returns the response, so these escape its
retry logic.
Retry such failures inside `makeRequest` with bounded exponential
backoff, scoped to idempotent methods (GET/HEAD) so writes are never
replayed. This fixes the reported `events.list` parse failure at the
adapter layer.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(core): propagate exhausted transient world errors to the queue
Pairs with the world-vercel in-adapter retry: when a response-body parse
failure survives the adapter's retries (or comes from a non-idempotent
write that is never retried in-process), it must not fail the run.
Re-throw such transient world errors from the replay loop so they
propagate to the queue handler, which replays the whole run — safe
because replay is idempotent. Schema-validation contract errors stay
fatal.

* Revert "fix(core): propagate exhausted transient world errors to the queue"

Approve — AI-resolved conflicts hold up, retry logic byte-identical to #2204
The backport bot called out that conflicts were AI-resolved, so I went through the diff carefully. The result is faithful.
Byte-identical to original
  • Changeset ✓
  • utils.test.ts ✓ — 113 lines added, identical to main
  • Retry logic ✓ — MAX_BODY_PARSE_RETRIES = 2, BODY_PARSE_RETRY_BASE_MS = 100, the IDEMPOTENT_METHODS Set, the canRetryBody = IDEMPOTENT_METHODS.has(...) derivation, the for (let attempt = 0; ;) retry loop with exponential backoff, and the WorkflowWorldError rethrow with code: 'PARSE_ERROR' — all byte-identical to origin/main:packages/world-vercel/src/utils.ts
Stable-shape adaptations
The +183/-97 numbers in utils.ts look different from main's +297/-124 because the surrounding file shape differs:
  • Stable has getWorkflowServerUrlOverride() (used for preview workflow-server URL routing) — not on main
  • Other small shape divergence from intervening main-only refactors
Spot-checked the exports list — only the new export const MAX_BODY_PARSE_RETRIES = 2; is added; all other exports unchanged.
Correctly omits
The original PR #2204 had 3 commits:
  • 283b52e75 fix(world-vercel): retry transient response-body parse failures
  • 7bb62e9f8 fix(core): propagate exhausted transient world errors to the queue
  • 1706a5e61 Revert "fix(core): propagate exhausted transient world errors to the queue"
So the net effect on main is the world-vercel change WITHOUT the core change (the core change was added then reverted). The backport correctly only ports the world-vercel side. The bot summary noted this explicitly.
Verified locally
  • pnpm install --frozen-lockfile ✓
  • pnpm turbo run build --filter @workflow/world-vercel ✓
  • pnpm --filter @workflow/world-vercel test ✓ (113/113)
  • All three new retry tests pass:

    • retries an idempotent GET when the body read fails, then succeeds ✓
    • throws PARSE_ERROR after exhausting retries for a GET ✓
    • does NOT retry a non-idempotent POST on body-parse failure ✓
CI
  • 85 success, 2 failures, 7 skipped
  • Failures: E2E Community World (Turso) and E2E Community World (Redis) — both pre-existing on stable's baseline (consistent across recent runs). Not caused by this PR.
Behavior summary
Sporadic PARSE_ERROR failures on idempotent reads (e.g., truncated stream body, gateway returning non-CBOR body) are now retried in-process with exponential backoff (100ms, 200ms; max 2 retries = 3 total attempts). Writes (POST/PUT/etc.) are NOT retried — replaying a write could double-apply it. Schema-validation failures remain non-retryable (retrying the same decoded payload would yield the same validation error).
Faithful backport. Approving.
