fix(cursor): detect echoed tool-result envelope and retry once with corrective action - #2669
Conversation
…o priming Live kimi-k3-1m probes mimicked the flattened tool-result envelope as their own reply in 2/7 runs. Append a one-line environment-provenance note after external history replay whenever a tool result was replayed. devlog: 260826_cursor_responses_gap/130_envelope_echo_guard.md

Cursor replay envelope guard
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds buffering and a one-time corrective retry for echoed tool-result envelopes, but merge readiness remains moderate because valid tool context may still be omitted and a late marker may suppress legitimate assistant output; the probe summary also overstates what was exercised. These issues should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

When the newest external tool-result turn exceeds the 512 KiB/blob replay budget, appending this user-role entry makes the pruning logic treat the guard—not the trailing tool result—as the final turn. The protected-suffix scan therefore finds no active toolResult, retains the small guard, and stops when the preceding oversized turn does not fit, dropping the tool output that the continuation must consume; this also regresses the existing oversized-active-result case in tests/cursor-blob.test.ts. Treat the guard as part of the protected active suffix, or append it after pruning while accounting for the limits.

script arguments and historical execution record at both sites.
In `@devlog/_plan/260805_ssh_app_server_catalog_race/001_two_host_comparison.md`:
- Around line 105-107: Correct the confirmation timestamps in the replacement
app-server verification narrative: replace 15:37:42 with the actual post-restart
start time, or explicitly identify it as the old process timestamp, so the
15:42:09 catalog comparison demonstrates the restarted process postdates the
catalog.
- Around line 36-42: Update the Markdown fences in the evidence blocks around
the comparison sections and the command block: specify text for the evidence
fences, specify sh for the command fence, and remove shell prompts or add
corresponding sample output so MD014 passes.
In
`@devlog/_plan/260805_ssh_app_server_catalog_race/002_startup_vs_sync_asymmetry.md`:

satisfies Markdown heading spacing.
In `@devlog/_plan/260813_apply_patch_tool_visibility/020_push_and_close.md`:
- Around line 9-13: Update the pre-push checklist to record the expected base
SHA from origin/dev and inspect the current commit range before pushing. Require
verification that only the intended fix commits are ahead of origin/dev,
preserving the existing git status, test, commit, and push steps.
In `@devlog/_plan/260813_bun_canary_dogfood/000_plan.md`:
- Around line 166-173: The WP-3 exit gate must match the acceptance criteria in
040_verification_deploy.md: add the 0.5 MiB/min heap-slope limit, require the
five-sample post-load retention check, and include an explicit request-error

the verification document as its single authoritative source.

to preserve the exact canary executable at a revision-named ignored path or
verified immutable artifact before installing stable Bun. Run canary commands
through that absolute path, run controls with stable Bun, and record and
validate the preserved path and revision in both documents.
In `@devlog/_plan/260813_bun_canary_dogfood/030_memory_patches.md`:
- Around line 159-200: Rewrite the workspace metadata cache section to reflect
the existing WORKSPACE_METADATA_MAX_ENTRIES, pruneWorkspaceMetadataCache, and
insertion-time pruning in workspace metadata collection. Remove the obsolete
proposal to add these safeguards, and state that refreshing an existing cwd must
also invoke pruneWorkspaceMetadataCache so unrelated expired entries are swept
while preserving the bounded cache behavior.
In `@devlog/_plan/260813_bun_canary_dogfood/040_verification_deploy.md`:
- Around line 92-99: Extend the sampler lifecycle around the load harness so it
remains active for at least five complete post-load samples and both required
sweep intervals before stopping. Preserve the one-minute sampling cadence and
continue extracting only scalar memory fields for committed evidence.
- Around line 176-183: Update the result-calculation procedure to compute the
least-squares heapUsed slope against each sample’s elapsed timestamp in minutes,
rather than sample index, then convert the dependent values to MiB and apply the
existing 0.5 MiB/min threshold to the resulting slope. Keep the warm-up start
and nearest-60-minute end definitions unchanged.
In
`@devlog/_plan/260813_openai_chat_baseurl_normalize/010_normalize_chat_baseurl.md`:
- Around line 77-79: Update the adapter-level assertion to call
createOpenAIChatAdapter with the trailing-slash base URL, then invoke its
buildRequest method using the existing parsed-request fixture and assert the

opening fence from an unlabeled fence to a text-labeled fence while preserving
the block contents.
In `@src/adapters/cursor/protobuf-request.ts`:
- Around line 308-313: Update the root-history pruning flow around
rootBlobCandidate and the pruning logic so the original history is pruned first
while reserving the guard blob and its byte budget, then append the guard after
the retained tool-result entry. Preserve a truncated terminal tool-result
envelope when it exceeds the root budget, and add a focused regression case in
cursor-envelope-echo-guard.test.ts covering the oversized terminal result and
exactly one subsequent guard note.

Correct the confirmation timestamps.
Line 105 says that the replacement app-server started at 15:37:42, while Line 106 gives a catalog mtime of 15:42:09. By the stale-state rule in Lines 44-47, that app-server still predates the catalog. Record the actual post-restart start time, or state that 15:37:42 belongs to the old process. The current text does not prove that the restart resolved the mismatch.

Line 182 defines a least-squares slope over sample values and then divides by MiB. That produces MiB per sample unless timestamps are exactly one minute apart. The sleep 60 loop can drift. Use timestamp delta in minutes as the independent variable before applying the 0.5 MiB/min threshold.

Assert buildRequest(parsed).url, not createOpenAIChatAdapter(...).url. createOpenAIChatAdapter returns a ProviderAdapter; the url field exists only on the AdapterRequest returned by its buildRequest method (src/adapters/openai-chat.ts:1336-1344, src/adapters/base.ts:66-70). A direct adapter-level url assertion will not type-check.

Preserve the active tool result during root-history pruning.
Lines 308-313 append a synthetic user entry before pruning. This makes the history suffix stop ending in toolResult, so lines 334-355 no longer retain or truncate the active tool-result block.
If the final tool output exceeds the root byte budget, pruning retains this small guard first and then drops the preceding user/assistant/tool-result turn. Cursor receives the guard but not the result that it must continue from.
Reserve the guard blob and byte budget, prune the original history first, then append the guard after a retained tool-result entry. Add a regression case in tests/cursor-envelope-echo-guard.test.ts with an oversized terminal tool result. Assert that the retained prompt contains the truncated tool-result envelope and one later guard note.
As per path instructions: “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

…orrective action The prompt-side guard note (v1) measurably failed live (2/7 -> 3/7 echo rate on kimi-k3-1m replay probes). Replace it with an observation boundary: an incremental prefix sniffer quarantines the first assistant text deltas of external tool-result continuations until they diverge from the replay envelope markers; a completed marker aborts the turn before any delta escapes and re-runs once in a fresh conversation with a corrective active turn. A second echo fails closed as an error. devlog: 260826_cursor_responses_gap/130_envelope_echo_guard.md (v2)
…layed tool results Live v3 probes leaked the envelope on user-action rounds too; the trailing toolResult condition was too narrow. User-action retries append the corrective note to the active text rather than replacing it.

Enforce the sniff window before matching a marker.
Line 59 checks the marker before Line 67 applies MAX_SNIFF_BYTES. For example, feed(" ".repeat(41) + "[Tool Result]") returns echo, although the marker starts outside the 40-byte sniff window. This suppresses the response, starts a fresh retry, and can fail the turn on a repeated normal response.
Check the byte and hold limits before probe.startsWith(marker). Add a regression test for a marker after 41 leading spaces.

Align the PASS summary with the checks that were actually exercised.
Lines 11-12 report Parallel 10-call as PASS, but lines 19-24 state that each model made only one tool call. This validates the final string, not parallel batching. Rename these rows or mark parallel batching as not exercised.

The runtime direction is useful, but this head is not merge-ready.
Two correctness blockers remain:
- The corrective guard is appended before root-history pruning. That changes the suffix away from
toolResult, so an oversized active tool result can be dropped while the small guard survives. Reserve the guard budget, prune the original history first, retain/truncate the terminal tool-result envelope, then append exactly one guard. - Marker matching runs before the 40-byte sniff-window check, so a marker beginning after 41 leading spaces can still trigger suppression/retry. Enforce byte/hold limits before accepting a marker.
Add focused regressions for both. Also remove the large unrelated historical devlog bundles from this PR; only the envelope-echo records belong here. The current operational summary additionally overclaims parallel batching that was not exercised. Keep the exact-head CI green after narrowing.
