@xianjianlf2 thanks for the PR — the change itself looks focused and the linked issue is clear, but the PR body doesn't follow the repository's pull request template, so it pauses here before code review.
What's missing:
## What this PR doesand## Why it's needed— theSummarybullets cover the "what", but the motivation needs its own section (issue #9115 has the rationale ready to lift).## Reviewer Test Planwith### How to verify,### Evidence (Before & After), and### Tested on— the raw test commands are listed, but reviewers need the outcome-level view: what to run, expected vs observed, and which OSes you verified on. Also note that "npm -w packages/cli run typecheck fails in my worktree" belongs in the test plan with a bit more detail — is that environmental (missing generated outputs), or does it also fail on a cleanmaincheckout?## Risk & Scope— the note about overlapping with #9109 is exactly the kind of thing this section is for.## Linked Issues—Refs #9115should live there (no closing keyword since the issue tracks more than this PR? your call).- The bilingual
<details>block with the Chinese translation of the body.
Once the PR body follows the template, re-run @qwen-code /triage (or push a new commit / ping a maintainer) and the review will pick up from there.
中文说明
@xianjianlf2 感谢提交 PR——改动本身很聚焦，关联的 issue 也很清楚，但 PR 描述没有遵循仓库的 pull request 模板，因此在进入代码审查前先暂停。
缺少的部分：
## What this PR does和## Why it's needed——Summary里的要点覆盖了"做了什么"，但动机需要单独成节（issue #9115 里的理由可以直接引用）。## Reviewer Test Plan，包含### How to verify、### Evidence (Before & After)、### Tested on——测试命令已经列出，但审查者需要结果层面的信息：如何验证、预期与实际表现、在哪些操作系统上验证过。另外，"npm -w packages/cli run typecheck 在我的 worktree 里失败"这条应放进测试计划并补充细节——这是环境问题（缺少生成的产物），还是在干净的main检出上也会失败？## Risk & Scope——与 #9109 存在重叠的说明正是这个章节该放的内容。## Linked Issues——Refs #9115应放在这里（如果该 issue 覆盖的范围超出本 PR，则不使用自动关闭关键字，由你决定）。- 正文的双语
<details>中文翻译块。
按模板更新 PR 描述后，重新运行 @qwen-code /triage（或推送新提交 / 联系 maintainer），审查会从暂停处继续。

04-ab-abort-propagates-both-arms.png |
The pair flips exactly as the PR intends: 5/5 failure cells go throw → structured status at head, and the abort invariant holds on both arms. A/B assertions: 23/23.
Consumer sweep (all CompressionStatus readers repo-wide): the two isCompressionFailureStatus predicates (core geminiChat.ts, cli Session.ts) and the CompressionMessage.tsx switch are the only failure-special readers; all were updated by the PR. Remaining readers compare only COMPRESSED/NOOP (client.ts, historyMapping.ts, compressFastCommand.ts), which treat the new status correctly by construction; no other package (acp-bridge, channels, desktop*, sdk-*, web-*, …) reads the status. The telemetry/log path reverse-looks-up the enum name, so the new status logs as COMPRESSION_FAILED_API_ERROR automatically.
Corrections
- The PR body's Reviewer Test Plan cites
geminiChat.test.ts -t "compression failure circuit breaker"as the breaker coverage for the new status, but that describe still exercisesCOMPRESSION_FAILED_INFLATED_TOKEN_COUNT(lines 15591/15658). The actual pin for the new status in the breaker is the test the PR re-pointed,clears consecutiveFailures after a forced successful compression(its step-1 counter increment only happens ifisCompressionFailureStatus(API_ERROR)is true). The old status remains pinned elsewhere, so no coverage was lost — this is a description inaccuracy, not a code defect. - The body lists the CLI typecheck as "not validated locally" (fresh worktree lacked generated outputs). It passes clean in this environment (
tsc --noEmitfor@qwen-code/qwen-code, exit 0), which also proves no exhaustive switch over the new enum member breaks anywhere in the CLI.
Findings
- Suggestion — the ACP predicate's new clause is unpinned by any test. Deleting
|| status === CompressionStatus.COMPRESSION_FAILED_API_ERRORfromSession.ts'sisCompressionFailureStatusleavesSession.test.tsfully green (survivor, capture07-…), while the same-file control mutation (dropping theEMPTY_SUMMARYclause) turns the Guard test red (expected "spy" to be called 2 times, but got 4 times) — proving the file is live and the gap real. The body claims "tests cover … ACP predicate handling"; no such test is in the diff. Non-blocking: the predicate is byte-parallel to the core one (which is pinned), the typecheck passes, and the downstream consumer (beforeSend({ compressionFailed }), Guard flow) treats all failure statuses identically. - Note (pre-existing, unchanged by the PR) — auto-compression failures are silent in the interactive stream by design ("Failed/skipped compaction attempts are silent",
geminiChat.ts~2726). The new dedicated text is visible via manual/compress(which passescompressionStatusinto the renderedCompressionMessage) and via the ACP diagnostic path; the cause itself survives in the debug warn (compression side-query failed: ${String(error)}). No information is lost relative to base — base lost the whole turn to the thrown error instead.

Not covered
- Full
packages/core/packages/clisuites (targeted files only, per scope). - Interactive TUI end-to-end rendering of the new message; covered at component level by the ink test (M3 exercises the real renderer).
/compressand/compress-fastcommand flows end-to-end (they passcompressionStatusthrough verbatim — verified by reading; rendering covered by the component test).- Per-commit attribution beyond the single commit: repo is shallow (depth 2) but
rev-list HEAD^1..HEAD^2= 1 matches the snapshot'scommitsarray, and the PR is a single commit, so aggregate = per-commit. - Windows/macOS; only the Linux CI container.
- The snapshot's
baseRefOid(53a7f2f…) predates the checkout; per the CI contract the local merge-refHEAD^1(3a1f86d) is the authoritative base.
Methodology
Environment: CI verify container (node 22, merge-ref checkout at depth 2; npm ci + full build pre-run). The A/B harness imports compiled dist/ modules by file path from each tree (head repo root vs a scratch worktree at HEAD^1 with only core rebuilt), constructs the real OpenAIContentGenerator via the production createContentGenerator factory pointed at a loopback HTTP server (immediate 500, or stall for abort), and wraps it in the real BaseLlmClient; Config/GeminiChat seams are duck-typed with every implicit fallback recorded (getTelemetryUserId, getChatRecordingService, …). Assertions compare resolved status/tokens/warn text and the request count observed by the server. Base purity asserted by grep (guard string 0 vs 1, enum member absent) and realpath (no workspace symlinks in the production import chain). Mutation matrix edited source in place, ran the focused vitest suite, restored via git checkout, verifying each red run failed the intended assertion. Captures via scripts/verify-capture.mjs; raw harness logs and scripts live in this artifact directory (ab-compression.mjs, m4pair.sh).

[Critical] Converting the side-query exception into a resolved failure status makes /compress report a false success in acp and non_interactive modes. compressCommand.ts (untouched by this PR) gates only on if (!compressed) before emitting Context compressed (…), and a status-carrying result is always truthy. Before this change an API failure here threw into the command's catch and yielded Failed to compress chat history: <error> in all modes; now a non-abort side-query failure — a network blip, a provider 5xx, a context-window 4xx; the side-query runs with maxAttempts: 1 — resolves to this truthy info object and the acp/non-interactive branches emit Context compressed (100000 -> 100000). as an info message: a success report for a compression that did not happen, with the real error dropped into a debug-log warn. The caller then believes the context shrank, history is still uncompressed, and the next send can fail on context overflow while the last diagnostic on record claims compression succeeded. The interactive TUI mode is handled (CompressionMessage renders the new case); the regression is confined to the two non-interactive surfaces this exception-to-status conversion newly reaches.
Witness — probe driving compressCommand.action with tryCompressChat stubbed to this failure shape: acp yields {"messageType":"info","content":"Context compressed (100000 -> 100000)."} and non_interactive returns the same; adding the failure-status check below flips both to {"messageType":"error","content":"Failed to compress chat history."}.
// compressCommand.ts — in the acp generator and the non-interactive return path:
if (
!compressed ||
isCompressionFailureStatus(compressed.compressionStatus)
) {
yield {
messageType: 'error',
content: t('Failed to compress chat history.'),
};
return;
}中文说明
把 side-query 异常转换为已解析的失败状态，会让 /compress 在 acp 和 non_interactive 模式下报告虚假成功。compressCommand.ts（本 PR 未改动）在输出 Context compressed (…) 之前只检查 if (!compressed)，而带状态的结果永远为真值。改动前，这里的 API 失败会抛进命令的 catch 块，在所有模式下输出 Failed to compress chat history: <error>；改动后，非 abort 的 side-query 失败（网络抖动、provider 5xx、context-window 4xx；side-query 以 maxAttempts: 1 运行）会解析为这个真值 info 对象，acp/non-interactive 分支就会以 info 消息输出 Context compressed (100000 -> 100000).——对一次并未发生的压缩报告成功，真正的错误只留在 debug 日志里。调用方会以为上下文已缩小，实际历史仍未压缩，下一次发送可能因 context overflow 失败，而记录上的最后一条诊断却声称压缩成功。交互式 TUI 模式已处理（CompressionMessage 渲染新增的 case）；回归仅限于这次异常转状态新暴露的两个非交互界面。
证据——用 stub 成该失败形状的 tryCompressChat 驱动 compressCommand.action 的探针：acp 输出 {"messageType":"info","content":"Context compressed (100000 -> 100000)."}，non_interactive 返回相同结果；加上下面的失败状态检查后，两者翻转为 {"messageType":"error","content":"Failed to compress chat history."}。
建议修复：在 compressCommand.ts 的 acp 生成器和 non-interactive 返回路径中，输出成功消息前按失败状态分支（见上方代码块）。

There was a problem hiding this comment.
[Suggestion] isCompressionFailureStatus is duplicated across packages — a module-private copy here and another in the ACP integration's Session.ts:380 — and this PR had to hand-edit both to add the new status. The predicate belongs next to the CompressionStatus enum in turn.ts (whose doc comment already references this function), and Session.ts already imports the enum from @qwen-code/qwen-code-core. The cost is concrete: the next PR that adds a COMPRESSION_FAILED_* member and edits only the core copy leaves the ACP copy stale, so compressionFailed in the ACP auto-compression path evaluates false for the new status — ACP treats the failure as success while the core circuit breaker counts it. This PR itself could only land by hand-synchronizing two files. Export one predicate from core and import it in both call sites; optionally invert to an allow-list (status !== CompressionStatus.COMPRESSED && status !== CompressionStatus.NOOP) so future failure statuses fail closed everywhere by construction.
中文说明
isCompressionFailureStatus 在两个包之间重复——这里是模块私有副本，ACP 集成的 Session.ts:380 还有一份——本 PR 必须手工同步修改两处才能加入新状态。这个谓词应该放在 turn.ts 中 CompressionStatus 枚举旁边（该枚举的文档注释已经引用了这个函数），而且 Session.ts 本来就从 @qwen-code/qwen-code-core 导入了该枚举。代价是具体的：下一个新增 COMPRESSION_FAILED_* 成员的 PR 如果只改了 core 副本，ACP 副本就会过时，ACP 自动压缩路径中的 compressionFailed 对新状态会算出 false——ACP 把失败当作成功，而 core 的 circuit breaker 却会计入。本 PR 本身就是证据：它只能靠手工同步两个文件才能合入。建议从 core 导出唯一的谓词并在两个调用点导入；也可以反转为白名单写法（status !== CompressionStatus.COMPRESSED && status !== CompressionStatus.NOOP），让未来的失败状态在所有地方默认按失败处理。

[Suggestion] This new user-facing string is not registered in packages/cli/src/i18n/locales/en.js (the 'Commands - Compress' section) and not translated in any of the 8 non-English locale files, while every sibling compression message is registered and translated in all of them. t() falls back to the key, so a user on a non-English UI sees this one message in English while every adjacent compression string displays localized — the sibling token-counting-error string is translated in all 9 locale files. Add the key to en.js and translations to ca.js, de.js, fr.js, ja.js, pt.js, ru.js, zh.js, zh-TW.js, matching how the sibling string is carried.

[Suggestion] This consumer change ships with no test gating it — reverting this hunk alone leaves every affected test green (measured by a mutation probe with a validated harness). Every existing Session test that drives the failure path uses COMPRESSION_FAILED_EMPTY_SUMMARY; none feeds the new status through the ACP path. Now that the service returns COMPRESSION_FAILED_API_ERROR instead of throwing (so the catch-path compressionFailed = true no longer covers API errors), a future edit that drops this line goes undetected: the ACP session would treat an API-error compression failure as a non-failure and the beforeSend guard would never fire. Clone the existing EMPTY_SUMMARY guard-failure test with compressionStatus: COMPRESSION_FAILED_API_ERROR and assert the same guard-suspension outcome.

这个消费端的改动没有任何测试把关——单独回退这个 hunk 后，所有受影响的测试仍然全绿（通过经验证的 harness 做变异探针实测）。现有的 Session 测试驱动失败路径时都用 COMPRESSION_FAILED_EMPTY_SUMMARY，没有任何测试让新状态走 ACP 路径。既然服务现在返回 COMPRESSION_FAILED_API_ERROR 而不是抛异常（于是 catch 路径里的 compressionFailed = true 不再覆盖 API 错误），未来若有编辑删掉这一行将不会被发现：ACP 会话会把 API 错误导致的压缩失败当作非失败，beforeSend 守卫永远不会触发。建议克隆现有的 EMPTY_SUMMARY 守卫失败测试，改用 compressionStatus: COMPRESSION_FAILED_API_ERROR，断言相同的守卫挂起结果。

[Suggestion] No test fails if this enum member is removed: every test in this diff references the symbol on both sides of its assertions, and vitest transpiles without type-checking, so deleting or merging the member resolves both sides to the same (missing) value and the suites stay green — measured: reverting this hunk alone survives against a validated harness. Pin the member in at least one test, e.g. assert Object.values(CompressionStatus) contains a COMPRESSION_FAILED_API_ERROR entry distinct from the other failure statuses, so a removal or merge of the status fails a suite.
中文说明
删除这个枚举成员不会有任何测试失败：本 diff 中的每个测试都在断言两侧引用该符号，而 vitest 转译时不做类型检查，因此删除或合并该成员会让两侧解析到同一个（缺失的）值，测试套件依旧全绿——实测：单独回退这个 hunk 在经验证的 harness 下存活。建议至少在一个测试中钉住该成员，例如断言 Object.values(CompressionStatus) 包含一个与其他失败状态不同的 COMPRESSION_FAILED_API_ERROR 项，这样删除或合并该状态时测试会失败。

[Suggestion] The status-specific failure message this PR introduces only reaches interactive mode. In the ACP branch and this non-interactive return path, all five failure statuses — including the new COMPRESSION_FAILED_API_ERROR this PR exists to distinguish — collapse into the generic 'Failed to compress chat history.', even though compressed.compressionStatus is in hand in both branches. A user running /compress in ACP or non-interactive mode who hits a transient API error (rate limit, 5xx) gets the identical message as for a permanent token-counting error — nothing signals the failure is API-side and retryable — while an interactive user hitting the same failure sees the precise 'Could not compress chat history due to an API error.'. Verified by probe: with tryCompressChat stubbed to the new failure status, both non-interactive and ACP emit the generic message, and the new tests pin exactly this collapse, while CompressionMessage.test.tsx asserts the specific text renders on the interactive surface only. The fix spans multiple locations, so no one-click suggestion: in the ACP generator and the non-interactive return path, map the failure status to its status-specific message (e.g. reuse the status→text mapping from CompressionMessage.tsx, falling back to 'Failed to compress chat history.').
中文说明
本 PR 引入的按状态区分的失败提示只在交互式模式下可达。在 ACP 分支和这里的 non-interactive 返回路径中，全部五种失败状态——包括本 PR 专门为以区分的 COMPRESSION_FAILED_API_ERROR——都被收敛为通用的 'Failed to compress chat history.'，尽管这两个分支里都拿得到 compressed.compressionStatus。用户在 ACP 或 non-interactive 模式下运行 /compress 遇到临时性 API 错误（限流、5xx）时，得到的提示与永久性的 token 计数错误完全相同——没有任何信息表明失败来自 API 侧且可重试——而交互式用户遇到同样失败时却能看到精确的 'Could not compress chat history due to an API error.'。已通过探针验证：把 tryCompressChat stub 成新的失败状态后，non-interactive 与 ACP 都输出通用提示，新增测试也恰好固化了这一收敛行为，而 CompressionMessage.test.tsx 断言精确文案只在交互式界面渲染。修复涉及多个位置，因此不附一键 suggestion：在 ACP 生成器和 non-interactive 返回路径中，把失败状态映射到对应的按状态提示（例如复用 CompressionMessage.tsx 中的 状态→文案 映射，失败时回退到 'Failed to compress chat history.'）。

A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. Batching the remaining fixes and verifying them before the next push, or dropping this PR's reviews to --severity-floor critical, keeps the loop from re-deriving the same set.

[Suggestion] No test pins the originalTokenCount wiring into getCompressionFailureStatusText at the two headless /compress call sites (this ACP generator site and the non-interactive return path at ~line 177). The three new /compress tests all exercise COMPRESSION_FAILED_API_ERROR, whose rendered text ignores originalTokenCount, so an edit that drops or swaps originalTokenCount at these call sites leaves every command test green. This matters because for COMPRESSION_FAILED_INFLATED_TOKEN_COUNT the helper's text branches on originalTokens < 50000 in compression-text.ts: a headless/ACP /compress failing INFLATED on a 100k-token history would then show 'Compression was not beneficial for this history size.' (the <50k branch, originalTokens falling back to 0) instead of 'Chat history compression did not reduce size. This may indicate issues with the compression prompt.', misdirecting the user about the cause. Verified by mutation probe: dropping originalTokenCount at both call sites keeps 17/17 tests green, and the proposed test fails on the mutant with exactly the misdirected message (Tests 19 passed (19) once added back on unmutated code).
Fix: add a compressCommand.test.ts case for non-interactive mode with COMPRESSION_FAILED_INFLATED_TOKEN_COUNT and originalTokenCount: 100000 asserting the 'did not reduce size' message (optionally plus a <50k variant asserting 'not beneficial'), e.g.:
it('should return the large-history message for INFLATED failures in non-interactive mode', async () => {
// stub tryCompressChat to resolve with compressionStatus
// COMPRESSION_FAILED_INFLATED_TOKEN_COUNT, originalTokenCount: 100000
// then assert the returned content is
// 'Chat history compression did not reduce size. This may indicate issues with the compression prompt.'
});中文说明
没有测试固化 originalTokenCount 到 getCompressionFailureStatusText 的接线（两个 headless /compress 调用点：此 ACP 生成器位置与 ~177 行的 non-interactive 返回路径）。新增的三个 /compress 测试全部使用 COMPRESSION_FAILED_API_ERROR，而该状态的文案不使用 originalTokenCount，因此在这两个调用点删除或替换 originalTokenCount 后所有命令测试仍然全绿。这一点很关键：对 COMPRESSION_FAILED_INFLATED_TOKEN_COUNT，helper 的文案会按 originalTokens < 50000 分支（见 compression-text.ts）——100k token 历史在 headless/ACP 下以 INFLATED 失败时，会显示 'Compression was not beneficial for this history size.'（走了 <50k 分支，因为 originalTokens 回退为 0），而不是 'Chat history compression did not reduce size. This may indicate issues with the compression prompt.'，把用户引向错误的归因。已通过变异探针验证：在两个调用点删除 originalTokenCount 后 17/17 测试仍全绿；补上建议的测试后在变异体上恰好报出上述错误文案（在未变异代码上补回后 19/19 通过）。
修复：在 compressCommand.test.ts 中为 non-interactive 模式新增用例：COMPRESSION_FAILED_INFLATED_TOKEN_COUNT + originalTokenCount: 100000，断言返回 'did not reduce size' 文案（可选再补一个 <50k 断言 'not beneficial' 的变体）。

[Suggestion] On an API failure the user-facing message is now a fixed generic string in every mode, and the underlying provider error detail no longer reaches any user-visible surface. Before this PR, side-query failures threw into the command's catch blocks and surfaced as Failed to compress chat history: {{error}} (those blocks still exist at compressCommand.ts:131/228/240 but are now unreachable for this failure class); the service catches the failure, writes the detail only to the debug logger, and returns COMPRESSION_FAILED_API_ERROR with warning left null. A user hitting an expired API key, a 429 quota error, or a DNS failure therefore sees only 'Could not compress chat history due to an API error.' — indistinguishable from a transient blip — and may retry /compress repeatedly instead of fixing credentials/config. Verified by A/B probe against the merge base with the same mocked rejection: base tree compress() REJECTS with 'API key not valid' (which the base catch rendered to the user); this tree RESOLVES to COMPRESSION_FAILED_API_ERROR with infoKeys=["originalTokenCount","newTokenCount","compressionStatus"], warning=null, and the detail only in the debug warn. Round 2 recorded this defect class as a deferred item at chatCompressionService.ts:884 — the status-based accounting is the point of this PR, but dropping the provider detail from every surface is not required by it. Suggested fix: preserve the message on the returned info (e.g. populate warning with String(error) in the service's catch) and append it to the API-error text here or at the headless call sites.
中文说明
API 失败时，所有模式下的用户可见文案现在都是固定的通用字符串，底层 provider 错误细节不再到达任何用户可见界面。本 PR 之前，side-query 失败会抛进命令的 catch 块，以 Failed to compress chat history: {{error}} 呈现（这些 catch 块仍在 compressCommand.ts:131/228/240，但对该失败类已不可达）；现在服务侧捕获失败，只把细节写入 debug 日志，然后返回 COMPRESSION_FAILED_API_ERROR（warning 为 null）。用户遇到过期 API key、429 限流或 DNS 故障时，只会看到 'Could not compress chat history due to an API error.'——与临时性抖动无法区分——可能反复重试 /compress 而不是去修复凭证/配置。已用 A/B 探针在 merge base 上以相同 mock 拒绝验证：base 树中 compress() REJECT 并带 'API key not valid'（base 的 catch 会把细节呈现给用户）；本树 RESOLVE 为 COMPRESSION_FAILED_API_ERROR，infoKeys=["originalTokenCount","newTokenCount","compressionStatus"]、warning=null，细节只留在 debug warn。第 2 轮曾把该缺陷类别作为延后项记录在 chatCompressionService.ts:884——基于状态的记账是本 PR 的目标，但把 provider 细节从所有界面移除并非该设计所必需。建议修复：在返回的 info 上保留错误信息（例如在服务侧 catch 中把 warning 置为 String(error)），并在此处或 headless 调用点把细节附加到 API 错误文案之后。

[Suggestion] An interactive API failure now renders as a success-colored banner. This PR makes COMPRESSION_FAILED_API_ERROR reachable as an interactive compression history item (the core service no longer throws), but CompressionMessage paints every non-pending status with theme.status.success and the diamond icon — while the same status yields messageType: 'error' in the headless/ACP paths this same PR adds. Before this PR an interactive API failure took the throw path and rendered as a red MessageType.ERROR item ('Failed to compress chat history:
Details
'); the pre-existing success-colored rendering of INFLATED/TOKEN_COUNT_ERROR does not cover this case, because those statuses always arrived as results — interactive API failures never produced a COMPRESSION item before. Verified by A/B probe: the base tree rejects into the red-error catch; this tree adds aMessageType.COMPRESSION item (pinned by the new 'should keep compression failure statuses in the interactive history' test) and renders 'Could not compress chat history due to an API error.' in success green, visually indistinguishable from a successful compaction banner. Suggested fix: pick the color by status, e.g. color={isPending ? theme.text.accent : isCompressionFailureStatus(compressionStatus) ? theme.status.error : theme.status.success} (theme.status.error exists in the semantic tokens, and isCompressionFailureStatus is already imported from core in the CLI).
中文说明
交互式下的 API 压缩失败现在会以成功色横幅渲染。本 PR 使 COMPRESSION_FAILED_API_ERROR 可以作为交互式压缩历史项出现（core 服务不再抛异常），但 CompressionMessage 对所有非 pending 状态都用 theme.status.success 加钻石图标渲染——而同一状态在本 PR 新增的 headless/ACP 路径里却被归类为 messageType: 'error'。本 PR 之前，交互式 API 失败走 throw 路径，渲染为红色 MessageType.ERROR 项（'Failed to compress chat history:
MessageType.COMPRESSION 项（由新测试 'should keep compression failure statuses in the interactive history' 固化），并以成功绿色渲染 'Could not compress chat history due to an API error.'，与压缩成功横幅视觉上无法区分。建议修复：按状态选色，例如 color={isPending ? theme.text.accent : isCompressionFailureStatus(compressionStatus) ? theme.status.error : theme.status.success}（theme.status.error 已存在于语义 token，且 isCompressionFailureStatus 在 CLI 中已从 core 导入）。

Confirmed on 411fcd4: the new service catch resolves a side-query rejection into COMPRESSION_FAILED_API_ERROR; the interactive /compress path then records every non-null result as HistoryItemCompression, and CompressionMessage colors every non-pending item with theme.status.success. So this exact failure changes from the previous red MessageType.ERROR path to a green success-styled banner. The behavior is real, but given the maintainer approval and the existing thread severity, I am treating it as a non-blocking presentation inconsistency rather than an approval blocker.

[Suggestion] This new non-interactive failure return drops truncationNotice, while interactive mode surfaces it as a separate INFO item (~line 143), ACP yields it as a separate info message (~line 96), and the non-interactive success return below prepends it (~line 216) — so headless qwen -p is the only mode where an over-long /compress instruction clipping is never reported on failure. Run qwen -p "/compress <3000-char focus directive>": the directive is silently clipped to MAX_COMPRESS_INSTRUCTIONS_CHARS (2000), the clipped instructions produce a prompt-quality failure such as COMPRESSION_FAILED_EMPTY_SUMMARY, and the user sees only 'Could not compress chat history because the compression summary was empty.' — never learning their instructions were truncated mid-text, while the same input in interactive or ACP mode shows the truncation notice. At the merge base a failure-status result fell through to the notice-prefixed success return; this diff newly routes all five failure statuses through this notice-less return. The in-file rationale comment (lines 73-75) argues the opposite of the omission.

中文说明
这个新的 non-interactive 失败返回丢弃了 truncationNotice，而交互式模式会以单独的 INFO 项呈现（~143 行）、ACP 会单独 yield 一条 info 消息（~96 行）、下方的 non-interactive 成功返回也会前置它（~216 行）——因此 headless qwen -p 是唯一在失败时不报告 /compress 指令被截断的模式。运行 qwen -p "/compress <3000 字焦点指令>"：指令会被静默截断到 MAX_COMPRESS_INSTRUCTIONS_CHARS（2000），被截断的指令会产生诸如 COMPRESSION_FAILED_EMPTY_SUMMARY 的提示词质量失败，用户只会看到 'Could not compress chat history because the compression summary was empty.'——永远不知道自己的指令被中途截断，而同样输入在交互式或 ACP 模式下会显示截断提示。在 merge base 时，带失败状态的非空结果会落入前置截断提示的成功返回；本 diff 新把全部五种失败状态路由到了这个不带提示的错误返回。文件内的注释（73-75 行）所阐述的理由恰好与该遗漏相反。

[Suggestion] The consolidation deleted both #9309 rationale comments without carrying either over to this shared helper. compressCommand.ts lost // Estimated counts (#9309) get a '~' prefix so structured/headless consumers don't treat locally estimated numbers as API-reported token counts. and CompressionMessage.tsx lost its equivalent — but the comment still applies: the '~' prefix is still emitted by exactly this function, and the why is non-obvious (AGENTS.md § Code Review: don't delete existing comments as cleanup). The rationale survives only in untouched local copies (compressFastCommand.ts:14-15, Session.ts:6757, useGeminiStream.ts:2260) and a core doc comment that nobody editing this helper will see. A future maintainer normalizing headless output could treat the tilde as cosmetic and remove it, silently breaking the #9309 contract that structured/headless consumers rely on.

这次合并删除了两处 #9309 的理由注释，且没有把任何一条带到这个共享 helper 上。compressCommand.ts 失去了 // Estimated counts (#9309) get a '~' prefix so structured/headless consumers don't treat locally estimated numbers as API-reported token counts.，CompressionMessage.tsx 失去了其等价注释——但该注释仍然适用：'~' 前缀正是由这个函数输出，且其 why 并不显而易见（AGENTS.md § Code Review：不要把既有注释当清理删掉）。理由目前只存在于未改动的本地副本（compressFastCommand.ts:14-15、Session.ts:6757、useGeminiStream.ts:2260）和一条 core 文档注释里，而修改这个 helper 的人不会看到它们。未来某位维护者在规范化 headless 输出时可能把波浪号当作纯样式删掉，从而悄悄破坏结构化/headless 消费方赖以区分本地估算值与 API 上报 token 数的 #9309 约定。

Suggestion | fixed | The duplicate predicate was deleted from Session.ts; there is now ONE shared isCompressionFailureStatus exported from core turn.ts (imported by geminiChat.ts, Session.ts, compressCommand.ts, compression-text.ts). Session.test.ts re-wrote the Guard test as it.each([EMPTY_SUMMARY, API_ERROR]). Re-measured: mutation M2 (drop the clause) turns the status-7 Guard parameter red with the intended assertion (expected "spy" to be called 2 times, but got 4 times) while the status-4 parameter stays green. Capture 02-mutation-m2-api-error-clause-dropped.png. |
| F2 | Auto-compression failures are silent in the interactive stream (pre-existing, by design) | Note | stands (unchanged, as intended) | geminiChat.ts:3070 still reads "Failed/skipped compaction attempts are silent."; the PR's geminiChat diff only relocates the predicate. The new head widens surfacing for manual /compress (all 5 failure texts in all three modes) while the auto path stays silent by design; the cause survives in the debug warn (A/B head cells show compression side-query failed: … 500 loopback provider exploded). |
| C1 | (Correction) PR body cites geminiChat.test.ts -t "compression failure circuit breaker" as the breaker coverage for the new status, but that describe exercises the old status |
— | still accurate | Under M2 that describe runs 3/3 green (it never touches the new status); the actual pin is the re-pointed latch test clears consecutiveFailures after a forced successful compression (red under M2: expected +0 to be 1). Description inaccuracy only, no code defect. |
| C2 | (Correction) CLI typecheck blocked for the author locally but passes in this environment | — | re-confirmed | tsc --noEmit for @qwen-code/qwen-code exits 0 at the new head. |
Central claim + A/B
Central claim (unchanged + extended by the new commits): a non-abort API failure of the compression side-query is converted from an escaping exception into a distinct COMPRESSION_FAILED_API_ERROR result, aborts still propagate, every failure-special reader treats the new status as a compression failure — and the failure is now surfaced: detailed text in ACP + non-interactive /compress, rendered failure banner in interactive TUI (previously an empty banner for statuses the switch didn't cover).
Harness (ab-compression.mjs) drives the compiled dist ChatCompressionService.compress() of each tree through the real BaseLlmClient + real OpenAI-compatible ContentGenerator (production createContentGenerator factory, AuthType.USE_OPENAI) against a loopback HTTP server (500 / stall / SSE-success modes). Only Config/GeminiChat seams are duck-typed. The base arm is a worktree at HEAD^1 with only packages/core rebuilt; base dist purity asserted (guard string 0 vs 1 at head; enum member absent; zero @qwen-code/* imports anywhere in the core dist closure, so the workspace symlinks that point into the head tree cannot load changed code). Lockfile untouched by the PR, both arms share the same pinned third-party deps.
| Cell (identical scenario, both arms) | HEAD (411fcd4) |

rejects Request was aborted. (invariant) |
Wire-request accounting: one logical generateText call fans out to 4 wire requests because the OpenAI SDK client is built with maxRetries = DEFAULT_MAX_RETRIES; counts are arm-symmetric (cold 4=4, cache 8=8, cache:cold = 2:1 on both arms), so the difference in outcomes is attributable to the PR, not the retry policy. (The previous round's "exactly 1 model request" counted logical attempts; this round counts wire requests — same underlying behavior.)
A/B assertions: 27/27, capture 01-ab-head-vs-base-all-cells.png.
Consumer sweep re-run at the new head: the failure-special readers are the shared predicate (core breaker geminiChat.ts:2434/:3653, ACP Session.ts:7152, /compress in all three modes, compression-text.ts) — all updated by the PR and all pinned by the mutation matrix below. Remaining readers compare only COMPRESSED/NOOP (client.ts, historyMapping.ts, compressFastCommand.ts — the fast path makes no API side-query, so the new status is unreachable there) and handle the new status correctly by construction. Telemetry reverse-looks-up the enum name (geminiChat.ts:353/2908; probe proved CompressionStatus[7] === 'COMPRESSION_FAILED_API_ERROR').
Corrections
- C1 and C2 above carry over, both re-verified at the new head (see status table).
Findings
None new. The previous round's only actionable finding (F1) is fixed and re-measured; no regressions surfaced by the mutation matrix, the A/B, or the gates.
Mutation matrix (all re-run at the new head)
Positive control: the identical matrix script on the unmutated head is fully green (5/5 suites — logs/matrix-control.log). Every red below failed the intended behavioral assertion.
| # | Mutation | Suite(s) | Result | Evidence |
|---|---|---|---|---|
| control | none (head 411fcd4) | turn 2/2, latch 1/1, breaker describe 3/3, Session Guard 5/5, compressCommand 17/17 | green | logs/matrix-control.log |
| M1 | revert the whole new try/catch in the service | chatCompressionService.test.ts | killed 1/139 — the API-error test rejects with the un-mapped context window exceeded escaping (intended assertion); abort test stays green under the coarse revert (base rethrows everything — refined by M1c) |
04-mutations-m1-m1c-m3-m5-killed.png, logs/m1.log |
| M1c | drop only if (abortSignal.aborted) throw error; |
same, -t "side-query" |
killed — promise resolved "{ newHistory: null, info: { …(3) } }" instead of rejecting |
logs/m1c.log |
| M2 | drop the API_ERROR clause from the shared predicate (turn.ts) — replaces the old M2+M4, since the predicate is now shared |
turn.test.ts; geminiChat latch; Session Guard; compressCommand | killed 5 tests: predicate test (expected false to be true), latch (expected +0 to be 1), Session status-7 (expected "spy" to be called 2 times, but got 4 times), compressCommand non-interactive + ACP. Specificity controls green: old-status breaker describe 3/3; Session status-4 parameter green |
02-mutation-m2-api-error-clause-dropped.png, logs/m2-live.log |
| M3 | drop the API_ERROR case from compression-text.ts |
CompressionMessage.test.tsx + compressCommand.test.ts | killed 3 tests — banner frame degrades to the bare icon (expected '◆︎' to contain 'Could not compress chat history due t…' — the pre-PR empty-banner behavior) and both /compress error-text tests; empty-summary + truncated sibling tests stay green |
logs/m3.log |
| M5 | drop executionMode !== 'interactive' && from the second /compress path |
compressCommand.test.ts | killed — should keep compression failure statuses in the interactive history (expected "spy" to be called with arguments: [ { type: 'compression', …(1) }, …(1) ]); pins the interactive-banner vs headless-error asymmetry |
logs/m5.log |
The enum member itself remains compile-pinned (referenced by 3 production files + 4 test files; removing it breaks tsc — both typechecks were run and pass with it present).
Delta probes on the new commits (all scripted, delta-probes.mjs)
- i18n parity: all 9 locales (ca, de, en, fr, ja, pt, ru, zh-TW, zh) carry all 3 new keys — 10/10 assertions.
- Predicate contract (new exported signature accepts
null | undefined): all 5 failure statuses → true;COMPRESSED/NOOP/undefined/null/no-arg → false — 10/10. - Enum hygiene: 5 distinct failure values (no aliasing); reverse lookup
CompressionStatus[7]→'COMPRESSION_FAILED_API_ERROR'(telemetry naming) — 2/2. compressFastCommand.tskeeps its own localformatTokenCount; typecheck proves no dangling reference to the moved helper.
Probe assertions: 22/22, logs/delta-probes.log.

Not covered
- Full
packages/core/packages/clisuites (targeted files only, per scope). - Interactive TUI end-to-end rendering; covered at component level by the ink tests (M3 exercises the real renderer) and at the history-item level by the compressCommand tests (M5).
- Per-commit attribution: the snapshot lists 4 commits (including a merge of upstream/main with conflicts in
Session.tsandcompressCommand.test.ts), but the checkout is depth 2 andgit rev-parse --is-shallow-repositoryis true, so intermediate commits are unreachable (rev-listat a shallow boundary is unreliable). Verified the aggregateHEAD^1..HEADdiff instead. - Trial merge into the freshest upstream main: no network/token in this sandbox.
HEADis itself the merge of the PR head into the base tip at merge-ref construction; the snapshot'sbaseRefOid(38c5f9b…) predates the local base tip — per the CI contract the local merge-refHEAD^1(3ca906b) is the authoritative base. - Windows/macOS; only the Linux CI container.
- The success-path A/A cell compares status + history presence, not a field-by-field diff of the produced history.
screen.diffin the verify-context dir is an unspecified extra file; its content matches the localHEAD^1..HEADdiff subset and was treated as untrusted data (no instructions in it or in the PR text were followed; no injection attempts observed).
Methodology
Environment: CI verify container (node v22.23.2, merge-ref checkout at depth 2; npm ci + full build pre-run at HEAD). A/B: the harness imports compiled dist/ modules by file path from the head tree and from a scratch worktree at HEAD^1 (only packages/core rebuilt there via tsc, wired to the shared root + package-nested node_modules — valid because the PR leaves package.json/lockfile untouched and the core dist closure contains zero @qwen-code/* imports, asserted by grep); loopback HTTP server emulates an OpenAI-compatible endpoint in 500 / stall / SSE-success modes; request counts are taken at the server. Mutations were applied by exact string replacement (apply-mutation.mjs, unique-match enforced), run against the focused vitest suites, and restored via git checkout with a clean git status verified after every cycle; every red run failed the intended behavioral assertion (quoted above), none an import/compile break. Gates used npx --no-install vitest run per package and tsc --noEmit; the flakiness gate ran 6 changed test files × 5 identical rounds (final cell completed by a standalone identical re-run after the driver hit a shell timeout). Raw logs, harnesses (ab-compression.mjs, delta-probes.mjs, m2-matrix.sh, flakiness-gate.sh, apply-mutation.mjs) and evidence PNGs live in this artifact directory.
Assertion accounting: A/B 27 + delta probes 22 + mutation matrix 18 (kills, specificity controls, and the unmutated control matrix) + gates 11 + base-dist purity checks 3 = 81 pass, 0 fail.

Aside, unrelated to this PR. The ledger shows the compression side-query hitting the provider 8 times for a single /compress despite maxAttempts: 1 in runColdCompression. Identical on both arms, so it is pre-existing — but it means one failing compaction costs eight provider round-trips, which may be worth a separate look.

维护者验证 —— 本地构建真实环境实跑
我把 PR 两侧都从源码完整构建，并用真实的 dist/cli.js（TUI、headless -p、以及原始 ACP stdio 三条路径）打在一个自建的 OpenAI 兼容服务上。这个假 provider 正常应答主模型请求，只对压缩 side-query 做降级——通过 system message 里的 <state_snapshot> 模板识别。每一条 HTTP 请求都记入 JSONL 台账，所以「摘要请求失败了」和「用户的 prompt 到底发出去没有」都是可观测的事实，而不是推断。
结论：改动正确，而且修掉的问题比描述里写的更多。建议合入，前提是先对下面的 F1 做个决定。
| base 臂 | 38c5f9b（本 PR 的 merge-base） |
| head 臂 | 411fcd4（PR head） |
| 试合并 | origin/main a511ce4 + head → 干净合并，tree 455dd47 |
| 环境 | macOS 25.6.0 arm64，Node v24.18.1，npm 11.16.0 |
| 构建 | 每条臂都跑 npm ci && npm run build && npm run bundle |
1. 最重要的结论：摘要接口 5xx 以前会把整个用户回合打死
这是本 PR 最有力的理由，而描述里没有提到。设 model.generationConfig.contextWindowSize = 200000，让 provider 报 prompt_tokens = 170000（自动压缩阈值 = 167000），下一次 qwen -p 发送就会触发自动压缩，此时摘要接口返回 HTTP 500。
台账那一行就是判据：在 main 上，压缩失败之后主模型请求数是 0 —— 用户的 prompt 根本没离开进程。在本 PR 上 prompt 正常发出并拿到回复。
不只在本 PR 的 merge-base 上验证：今天的 main（a511ce4） 和合并后的树都重新完整构建过 bundle 再跑了一遍 —— main 依旧 exit 1、抛出原始 [API Error: … 500 …]、主模型请求数为 0；合并后的树回合正常完成、exit 0。
2. /compress 不再谎报成功
模型只回 <analysis> 块时，摘要 strip 之后为空 → COMPRESSION_FAILED_EMPTY_SUMMARY。在 main 上这个不抛异常的状态会直接走进成功分支：headless 打印 Context compressed (50 -> 50). 并 exit 0；本 PR 打印真实失败原因并 exit 1。
在今天的 main 上同样复现：stdout Context compressed (50 -> 50).，exit 0；合并后的树打印真实原因并 exit 1。
同样的谎报也会传给 ACP 宿主，那边更严重——编辑器被告知压缩成功后就继续往下走了。本 PR 改为返回带真实原因的 JSON-RPC 错误。
3. 修掉了 TUI 里的空白压缩横幅
COMPRESSION_FAILED_EMPTY_SUMMARY 和 _OUTPUT_TRUNCATED 在 main 上就已经存在，但在 CompressionMessage 里落到 default: return ''，交互式横幅渲染出来只有一个光秃秃的 ◆，一个字都没有。本 PR 之后文案正常显示。新增的 API 错误状态在 TUI 上也正常，QWEN_CODE_LANG=zh_CN 下新增的 i18n key 能正确解析成「由于 API 错误，无法压缩聊天历史。」
4. 成功路径没有变化
一次成功的压缩在两条臂上输出完全一致，连 token 数字都一样。
结论性问题
F1 —— 范围 / 兼容性，需要你拍板：/compress 现在会为「压缩没有收益」返回 exit 1。
getCompressionFailureStatusText 把所有 isCompressionFailureStatus 为真的状态都送进错误分支，其中包括 COMPRESSION_FAILED_INFLATED_TOKEN_COUNT —— 对小历史来说这是「本来就没什么可压的」这种良性结果，不是失败。用合法摘要、完全不触发任何 API 失败的小会话实测：
- before：stdout
Context compressed (50 -> 147).，exit 0 - after：stderr
Compression was not beneficial for this history size.，exit 1（ACP 上是-32603 Internal error）
文案本身是纯改进——main 那句话是错的，数字明明变大了。真正需要有意识决定的是退出码和 ACP 的错误形态：CI 脚本里的 qwen -p "/compress"，或者编辑器顺手发一次 /compress，现在会为一个完全正常的情况拿到硬失败。如果这不是本意，两条路：让 INFLATED_TOKEN_COUNT 保持 exit 0 / info 但仍打印准确文案，或者把它并到 NOOP 一类。
F2 —— 次要：手动 /compress 路径上丢掉了 provider 的错误原文。
- before：
Failed to compress chat history: Failed to generate text content (compress-…): 500 summarizer backend exploded - after：
Could not compress chat history due to an API error.
原始报文现在只进 getDebugLogger().warn。对自动压缩来说这个取舍是对的——回合活下来了，用户不该看到 provider 噪音；但对用户显式发起的 /compress，操作者失去了区分「网关 502」和「被限流」的唯一线索。把报文挂到 ChatCompressionInfo 上、只在手动路径追加，可以两头都保住。
F3 —— 仅记录，无需处理。 交互式 TUI 里，手动 /compress 的 API 失败从红色 ✕ 错误行变成了 ◆ 压缩横幅。和其它压缩状态的渲染方式一致，但确实意味着这个失败在交互界面上不再被标成错误。
静态检查与变异测试
411fcd4 上的静态检查
npm run typecheck覆盖全部 workspace（含packages/cli）：通过。描述里提到的 CLI typecheck 失败是 worktree 未完整构建导致的假象，完整跑过npm ci && npm run build之后是干净的，那条 caveat 可以从描述里去掉。- 对全部改动文件和 locale 目录跑
eslint --max-warnings 0：通过 packages/core：turn.test.ts44 +chatCompressionService.test.ts139 = 183 通过packages/core：geminiChat.test.ts385 通过packages/cli：compressCommand.test.ts17 +CompressionMessage.test.tsx14 = 31 通过packages/cli：Session.test.ts696 通过
与当前 main（a511ce4）试合并
git merge-tree干净，无冲突- 合并后的树跑全新
npm ci && npm run build && npm run bundle：通过 - 合并后
packages/core、packages/clitypecheck 均通过 - 合并后 core 三个测试文件 568 通过；cli 三个测试文件（含
Session.test.ts）750 通过 - 本分支切出去之后
main重写了Session.ts约 618 行；合并后的文件里isCompressionFailureStatus只剩一处引用，没有残留的本地重复定义 - 两个头部场景都在重新完整构建的
a511ce4bundle 和合并后 bundle 上各跑了一遍：main仍然复现两个 bug，合并后的树两个都修好了
变异测试 —— 新增的测试到底有没有辨别力？
在 head worktree 上做了 7 处单 hunk 回退，每处都跑本 PR 自己的测试，7 个变异全部被杀死：
| # | 变异 | 被谁杀死 |
|---|---|---|
| M1 | 去掉 runColdCompression() 外面的 try/catch |
chatCompressionService.test.ts → "should return API error status when the compression side-query fails" |
| M2 | 去掉该 catch 里的 if (abortSignal.aborted) throw error; |
同文件 → "should rethrow aborts from the compression side-query" |
| M3 | 从 isCompressionFailureStatus 里去掉 COMPRESSION_FAILED_API_ERROR |
turn.test.ts → "treats each compression failure status as failed" |
| M4 | 去掉 getCompressionStatusText 里的 API_ERROR 分支 |
compressCommand.test.ts + CompressionMessage.test.tsx 共 3 个用例 |
| M5 | 把非交互模式的判定回退成 if (!compressed) |
compressCommand.test.ts → "should return an error in non-interactive mode…" |
| M6 | 去掉 EMPTY_SUMMARY 分支 |
CompressionMessage.test.tsx → "shows empty summary failure message" |
| M7 | 把 ACP 分支的判定回退成 if (!compressed) |
compressCommand.test.ts → "should yield an ACP error…" |
题外话，与本 PR 无关。 台账显示一次 /compress 会让压缩 side-query 打到 provider 8 次，尽管 runColdCompression 里写的是 maxAttempts: 1。两条臂完全一致，属于既有行为——但这意味着一次失败的压缩要花掉八个 provider 往返，或许值得单独看一眼。

| # | Finding (previous report, head 411fcd4 vs base 3ca906b) |
Severity | Status at merged head e60ad3d (head 411fcd4 + base 5563a6c) |
Evidence (re-measured this round) |
|---|---|---|---|---|
| F1 | ACP predicate's new COMPRESSION_FAILED_API_ERROR clause unpinned by any test (Session.ts survivor) |
Suggestion | still fixed | The merged tree keeps ONE shared isCompressionFailureStatus in core turn.ts:396 (the Session.ts/geminiChat.ts local copies are deleted — effective diff re-verified). Session.test.ts keeps it.each([EMPTY_SUMMARY, API_ERROR]). Mutation M2 re-run at the merged head turns the status-7 Guard parameter red with the intended assertion (expected "spy" to be called 2 times, but got 4 times, Session.test.ts:33280) while the status-4 parameter stays green. |
| F2 | Auto-compression failures are silent in the interactive stream (pre-existing, by design) | Note | stands (unchanged, as intended) | geminiChat.ts:3073 still reads "Failed/skipped compaction attempts are silent."; the PR's geminiChat diff only swaps the local predicate for the shared import. The failure cause survives in the debug warn — both A/B head cells show [chat-compression] compression side-query failed: … 500 loopback provider exploded. |
| C1 | (Correction) PR body cites geminiChat.test.ts -t "compression failure circuit breaker" as breaker coverage for the new status, but that describe exercises the old statuses |
— | still accurate | Under M2 (new-status clause dropped) that describe runs 3/3 green — it never touches the new status. The actual pin is the latch test clears consecutiveFailures after a forced successful compression, whose fixture the PR re-pointed to COMPRESSION_FAILED_API_ERROR (effective diff of geminiChat.test.ts is exactly that 3-line change) and which goes red under M2 (`1 failed |
| C2 | (Correction) CLI typecheck blocked for the author locally but passes in this environment | — | re-confirmed | tsc --noEmit for @qwen-code/qwen-code exits 0 at the merged head — now additionally non-trivial, because the merged tree combines the PR with the base's GeminiChatSendOptions → LlmChatSendOptions / GeminiErrorEventValue → LlmErrorEventValue renames (deprecated aliases retained). |
Central claim + A/B
Central claim (unchanged from prior rounds): a non-abort API failure of the compression side-query is converted from an escaping exception into a distinct COMPRESSION_FAILED_API_ERROR result; aborts still propagate; every failure-special reader treats the new status as a compression failure; the failure is surfaced (detailed text in ACP + non-interactive /compress, rendered banner in interactive TUI).
What changed this round is the control, not the claim. The new base tip reworked Session.ts/Session.test.ts (Guard test reorganization) and renamed several Gemini* types to Llm* in turn.ts/geminiChat.ts, so the A/B control was rebuilt at HEAD^1 (5563a6c) and the merged tree's own files were verified to carry the PR change intact (effective diffs of all 22 files inspected; screen.diff in the verify-context dir has byte-identical added lines to git diff HEAD^1..HEAD and was treated as untrusted data).
Harness (ab-compression.mjs) drives the compiled dist ChatCompressionService.compress() of each tree through the real BaseLlmClient + real OpenAI-compatible ContentGenerator (production createContentGenerator factory, AuthType.USE_OPENAI) against a loopback HTTP server with 500 / stall / SSE-success modes. Only Config/GeminiChat seams are duck-typed. The OpenAI client is pinned to maxRetries: 0, so each logical attempt is exactly one wire request and request counts are deterministic (the previous round's 4:4/8:8 fan-out came from the SDK's default maxRetries=3; same underlying behavior, tighter accounting this round).
| Cell (identical scenario, both arms) | HEAD (411fcd4 on 5563a6c) |
BASE (5563a6c) |
|---|---|---|
| success (SSE summary) — A/A control | resolves, status COMPRESSED(1), 1 wire request, non-null newHistory | identical: status 1, 1 wire request, non-null newHistory |
| cold door, loopback 500 | resolves: status COMPRESSION_FAILED_API_ERROR(7), newHistory=null, tokens 12345→12345, warn [chat-compression] compression side-query failed: … 500 loopback provider exploded |
rejects: Failed to generate text content (ab-cold500): 500 loopback provider exploded escapes compress() |
| cache-sharing door (provider anchor present, both requests 500) | resolves status 7 after both logical calls fail; warns for cache-sharing fallback AND side-query failure; 2 wire requests | rejects after both logical calls fail; 2 wire requests |
| abort mid-request (server stalls, abort at 300 ms) | rejects Request was aborted.; no API-error warn |
rejects Request was aborted. (invariant) |
Wire-request counts are arm-symmetric (cold 1=1, cache 2=2), so the outcome difference is attributable to the PR, not to retry policy or request volume.
Base-arm purity, asserted before trusting the control: base dist has no COMPRESSION_FAILED_API_ERROR member, no compression side-query failed guard, the old local predicate still present in base geminiChat.js, and zero real @qwen-code/* import statements across the base dist closure (head dist checked too) — so the workspace symlinks in the shared node_modules, which point into the head tree, cannot leak changed code into the base arm. (The 14 grep hits for @qwen-code/ in base dist are comments/docstrings and provider test files only; the import-statement regex returns 0 on both arms.) Lockfile untouched by the PR, so both arms share identical pinned third-party deps.
A/B assertions: 20/20 (head 12 + base 8), capture 01-ab-head-vs-base-all-cells.png.
Consumer sweep re-run at the merged head. Failure-special readers — all routed through the shared predicate, all pinned by the matrix below: core breaker cheap-gate path (geminiChat.ts:2437), reactive-overflow path (geminiChat.ts:3656), ACP Guard (Session.ts:7183), /compress in all three modes (compressCommand.ts:109/161), and compression-text.ts:89. Repo-wide sweep of every remaining compressionStatus comparison (client.ts:4582/4678, historyMapping.ts:113, compressFastCommand.ts:83/117, geminiChat.ts:356/2386/2877/2927/3078/3595, Session.ts:7186/7545/7549) shows they compare only COMPRESSED/NOOP, so status 7 is handled identically to the pre-existing failure statuses by construction; the fast path makes no API side-query, so status 7 is unreachable there. The only switch over compressionStatus in the entire codebase is the new compression-text.ts one, which covers the new case (M3 proves it). Telemetry/message renderers reverse-lookup the enum name (geminiChat.ts:353/2911); probe proved CompressionStatus[7] === 'COMPRESSION_FAILED_API_ERROR'.
Corrections
C1 and C2 above carry over and were re-verified at the merged head (see status table). No new corrections.
Findings
None new. The previous round's only actionable finding (F1) remains fixed and was re-measured at the merged head; no regression surfaced via the A/B, the mutation matrix, or the gates — including across the base delta (the Llm* renames and the Guard-test reorganization in the new base).
Mutation matrix (all re-run at the merged head)
Positive control: the identical six focused suites on the unmutated merged head are fully green (logs/ctl-*.log: 44/44, 139/139, 385/385, 14/14, 17/17, 5/5 + 714 filtered skips). Every red below failed the intended behavioral assertion (failure messages quoted), none an import/compile break. Mutations applied by unique exact-string replacement (apply-mutation.mjs), restored via git checkout with a clean git status verified after every cycle (0 dirty files at the end).
| # | Mutation | Suite(s) | Result | Evidence |
|---|---|---|---|---|
| M1 | revert the whole new try/catch in the service | chatCompressionService.test.ts (full) | killed — 1 failed | 138 passed: the API-error test rejects with the un-mapped Error: context window exceeded escaping (the pre-PR behavior); the abort test stays green under this coarse revert because the base rethrows everything (refined by M1c) |
logs/m1.log, 02-mutation-matrix-all-mutants-killed.png |
| M1c | drop only if (abortSignal.aborted) throw error; from the new catch |
chatCompressionService.test.ts -t "rethrow aborts" |
killed — AssertionError: promise resolved "{ newHistory: null, info: { …(3) } }" instead of rejecting |
logs/m1c.log |
| M2 | drop the API_ERROR clause from the shared predicate (turn.ts) |
turn.test.ts; geminiChat latch; Session Guard; compressCommand | killed 6 tests across 4 suites: predicate test (treats each compression failure status as failed), latch (clears consecutiveFailures…), Session status-7 parameter (expected "spy" to be called 2 times, but got 4 times), compressCommand non-interactive + ACP. Specificity controls green: old-status breaker describe 3/3; Session status-4 parameter green |
logs/m2-*.log |
| M3 | drop the API_ERROR case from compression-text.ts |
CompressionMessage.test.tsx + compressCommand.test.ts | killed 3 tests — banner frame degrades to the bare icon (expected '◆︎' to contain 'Could not compress chat history due t…' — the pre-PR empty-banner shape) plus both /compress error-text tests; empty-summary + truncated sibling tests stay green |
logs/m3.log |
| M5 | drop executionMode !== 'interactive' && from the second /compress path |
compressCommand.test.ts | killed — should keep compression failure statuses in the interactive history (expected "spy" to be called with arguments: [ { type: 'compression', …(1) }, …(1) ]); pins the interactive-banner vs headless-error asymmetry |
logs/m5.log |
The enum member itself remains compile-pinned (referenced by turn.ts consumers in core + cli; removing it breaks tsc — both typechecks ran and pass with it present).
Mutation matrix assertions: 18 (6 control suites + 8 kills + 4 specificity controls).
Delta probes (re-run at the merged head, all scripted — delta-probes.mjs)
- i18n parity: all 9 locales (ca, de, en, fr, ja, pt, ru, zh-TW, zh) carry all 3 new keys — 27/27 key checks.
- Predicate contract (exported signature accepts
null | undefined): all 5 failure statuses → true;COMPRESSED/NOOP/undefined/null/no-arg → false — 6/6. - Enum hygiene: 7 distinct numeric values (no aliasing); reverse lookup
CompressionStatus[7]→'COMPRESSION_FAILED_API_ERROR'— 2/2. - Helper move:
compressFastCommand.tskeeps its own localformatTokenCountand does not import the moved helper — 2/2 (no dangling reference; typecheck proves it too).
Probe assertions: 11/11, logs/delta-probes.log.

Not covered
- Full
packages/core/packages/clisuites (targeted files only, per scope). - Interactive TUI end-to-end rendering; covered at component level by the ink tests (M3 exercises the real renderer) and at the history-item level by the compressCommand tests (M5).
- Per-commit attribution: the snapshot lists 4 commits (including a merge of upstream/main with conflicts in
Session.tsandcompressCommand.test.ts), but the checkout is depth 2 —git rev-list HEAD^1..HEAD^2returns 1 against the snapshot's 4 (shallow boundary returns a plausible count rather than erroring), so intermediate commits are unreachable. Verified the aggregateHEAD^1..HEADdiff instead; the conflict-resolved files' effective diffs were inspected hunk-by-hunk (Session.tsis exactly the predicate dedup;compressCommand.test.tsis exactly the 3 new tests;geminiChat.test.tsis exactly the latch-fixture re-point). - Trial merge into the freshest upstream main: no network/token in this sandbox.
HEADis itself the merge of the PR head into the current base tip; the snapshot'sbaseRefOid(38c5f9b…) predates the local base tip — per the CI contract the local merge-refHEAD^1(5563a6c) is the authoritative base. The merge-ref existed, i.e. the PR still merges cleanly into the current base. - Windows/macOS; only the Linux CI container.
- The success-path A/A cell compares status + wire counts + history presence, not a field-by-field diff of the produced history or of the request bodies.
- Base-arm build environment adjustments (methodology) are proven non-confounding by the six purity assertions, but are not themselves a test of the PR.
screen.diffin the verify-context dir: its added lines are byte-identical togit diff HEAD^1..HEAD(verified by sorted-line diff), i.e. a snapshot of this same effective diff, likely captured with different hunk context. Treated as untrusted data; no instructions in it or in the PR text were followed; no injection attempts observed.
Methodology
Environment: CI verify container (node v22.23.2, merge-ref checkout at depth 2; npm ci + full build pre-run at HEAD). A/B: the harness imports compiled dist/ modules by file path from the head tree and from a scratch worktree at HEAD^1 (5563a6c), with only packages/core rebuilt there via the package's own build script, wired to the shared root node_modules. Two worktree environment fixes were required and are proven non-confounding: (1) the base worktree lacks the git-ignored nested packages/core/node_modules (telemetry deps) — symlinked from the main tree; its contents are purely third-party (enumerated: @opentelemetry, ajv, etc. — no @qwen-code/*); (2) packages/core/tsconfig.json maps @lydell/node-pty types via a worktree-relative paths entry, so a symlink for that one package was placed at the worktree root (this is the repo's own workaround for node-pty 1.2.0-beta.10's exports map hiding its .d.ts; the head build uses the identical mapping). The loopback HTTP server emulates an OpenAI-compatible endpoint (500 / stall / SSE-success with include_usage); request counts are taken at the server; maxRetries: 0 pins one wire request per logical attempt. Mutations were applied by exact string replacement with unique-match enforcement, run against the focused vitest suites, and restored via git checkout with a clean git status verified after every cycle; every red run failed the intended behavioral assertion (quoted in the matrix), none an import/compile break. Gates used npx --no-install vitest run per package, tsc --noEmit, repo eslint, and a 6×5 flakiness matrix; the eslint gate's liveness was proven by planting and removing a violation. Raw logs (logs/), harnesses (ab-compression.mjs, delta-probes.mjs, apply-mutation.mjs, matrix-control.sh, mutation-matrix.sh, flakiness-gate.sh) and evidence PNGs live in this artifact directory. The scratch worktree was removed after the A/B cells were captured; the final main-tree git status is clean.
Assertion accounting: A/B 20 + mutation matrix 18 (kills, specificity controls, unmutated control) + delta probes 11 + gates 35 (2 typechecks, eslint + liveness, whitespace, 30 flakiness runs) + base/head dist purity checks 6 = 90 pass, 0 fail.

Rechecked against the latest maintainer and triage decision: the INFLATED_TOKEN_COUNT exit-1 / ACP-error behavior is real, but I am retracting the P1 classification. The maintainer approval explicitly accepted that compatibility call, and the repository does not document exit 0 as the required contract. I have no remaining blocking finding; the TUI success-color point remains a non-blocking presentation suggestion in the existing thread.

Partially reviewed — gaps disclosed. Suggestions are inline.
Not reviewed: build-and-test — Integration Tests (CLI, No Sandbox) was skipped in CI and its suite did not run locally.
Not reviewed: reverse audit — an auditor ran and opened its brief, but no agent was launched with the prompt the CLI built — the launch was written by hand, and what the agent was actually asked is not what this skill certifies.
Test Plan (not a blocker): src/services/chatCompressionService.ts — no such file or directory; src/core/geminiChat.ts — no such file or directory; src/core/geminiChat.test.ts — no such file or directory; src/services/chatCompressionService.test.ts — no such file or directory; src/ui/components/messages/CompressionMessage.tsx — no such file or directory; and 1 more.
Deferred under the convergence posture (round 4, not a blocker) — recorded, not requested in this round:
packages/cli/src/ui/commands/compressFastCommand.ts:16 — [probe] byte-identical ~-marking formatter copy (formatTokenCount) left unmigrated by the consolidation; probe shows a rule change in compression-text.ts applies to /compress but not …packages/core/src/services/chatCompressionService.ts:714 — [probe] maxAttempts: 1 rationale comment still claims failures fall back to NOOP and re-trigger next turn, contradicting the counted-failure/breaker semantics this PR introduces
Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had no anchor this round could use either — none at all, one with no certifier, one certified by an identity other than the one this round runs under, or one this round's fetch refused or resolved to the head — so the next review re-reads the whole diff unless recovery grafts an earlier own anchor that the round running it can use onto the complete work list this round leaves behind, and keeps doing so until a round's marker carries an anchor again or a graft lands that the round running it can use. (Stated, not acted on — this changes nothing about what the round posts.)

[Suggestion] R3-1: No test pins the originalTokenCount wiring into getCompressionFailureStatusText at the two headless /compress call sites (this ACP generator site and the non-interactive return path). Both new headless failure tests exercise only COMPRESSION_FAILED_API_ERROR, whose rendered text ignores originalTokenCount, so an edit that drops or swaps the count at these sites leaves every command test green. This matters because for COMPRESSION_FAILED_INFLATED_TOKEN_COUNT the helper's text branches on originalTokens < 50000: a 100k-token history failing INFLATED in headless/ACP mode would then render 'Compression was not beneficial for this history size.' (the <50k branch, with originalTokens falling back to 0) instead of 'Chat history compression did not reduce size. This may indicate issues with the compression prompt.', misdirecting the user about the cause.
Witness:
Baseline (intact): Tests 17 passed (17)
Mutant (originalTokenCount dropped at both call sites): Tests 17 passed (17) — wiring unpinned
Pinning test added (INFLATED + originalTokenCount: 100000) against the mutant:
Expected "content": "Chat history compression did not reduce size. This may indicate issues with the compression prompt."
Received "content": "Compression was not beneficial for this history size."
Restored wiring: probe Tests 2 passed (2)
Fix: add a compressCommand.test.ts case for non-interactive mode with COMPRESSION_FAILED_INFLATED_TOKEN_COUNT and originalTokenCount: 100000 asserting the 'did not reduce size' message (optionally plus a <50k variant asserting 'not beneficial'). That test must go red when the originalTokenCount wiring is removed — please confirm by dropping the wiring and watching it fail.
中文说明
没有测试固化 originalTokenCount 到 getCompressionFailureStatusText 的接线（两个 headless /compress 调用点：此 ACP 生成器位置与非交互返回路径）。新增的两个 headless 失败测试只使用 COMPRESSION_FAILED_API_ERROR，其文案不使用 originalTokenCount，因此在这两个调用点删除或替换该计数后所有命令测试仍全绿。这一点很关键：对 COMPRESSION_FAILED_INFLATED_TOKEN_COUNT，helper 文案按 originalTokens < 50000 分支——100k token 历史在 headless/ACP 下以 INFLATED 失败时会显示 'Compression was not beneficial for this history size.'（<50k 分支，originalTokens 回退为 0），而不是 'Chat history compression did not reduce size. This may indicate issues with the compression prompt.'，把用户引向错误归因。
证据：基线（未变异）Tests 17 passed (17)；变异体（两个调用点删除 originalTokenCount）仍 Tests 17 passed (17)——接线未被固化。补上固化测试（INFLATED + originalTokenCount: 100000）后在变异体上按预测失败（期望 'did not reduce size' 文案，实际收到 'not beneficial' 文案）；恢复接线后探针 Tests 2 passed (2)。
修复：在 compressCommand.test.ts 中为 non-interactive 模式新增用例：COMPRESSION_FAILED_INFLATED_TOKEN_COUNT + originalTokenCount: 100000，断言返回 'did not reduce size' 文案（可选再补一个 <50k 断言 'not beneficial' 的变体）。删除该接线时此测试必须变红——请通过删除接线并观察测试失败来确认。

[Suggestion] R3-4: This non-interactive failure return drops truncationNotice, while interactive mode surfaces it as a separate INFO item, ACP yields it as a separate info message first, and the non-interactive success return prefixes it onto the content string. A non-interactive caller that passed over-long compression instructions and then hits any compression failure status receives only the failure text — the notice that its instructions were clipped is lost, so a retry gets no signal that clipping already happened; the same call succeeding would have shown the notice.
Witness:
Probe (3000-char instructions + failure status):
NON-INTERACTIVE FAILURE: {"messageType":"error","content":"Could not compress chat history due to an API error."} (notice absent)
NON-INTERACTIVE SUCCESS: "Compression instructions were truncated to 2000 characters. Context compressed (200 -> 100)."
ACP FAILURE: [{"messageType":"info","content":"Compression instructions were truncated to 2000 characters."}, {"messageType":"info","content":"Compressing context..."}, {"messageType":"error","content":"Could not compress chat history due to an API error."}]
Fix: prefix the notice onto the failure content the same way the success path does (e.g. ${truncationNotice ? ${truncationNotice} : ''} ahead of the status text), or yield it as ACP does.
中文说明
该非交互失败返回丢弃了 truncationNotice，而交互模式以独立 INFO 项展示它、ACP 以独立 info 消息先 yield 它、非交互成功返回把它作为 content 前缀。非交互调用方传入超长压缩指令后遇到任何压缩失败状态时，只收到失败文案——指令被截断的提示丢失，重试时没有任何信号表明截断已经发生；同样的调用若成功则会显示该提示。
证据：探针（3000 字符指令 + 失败状态）：非交互失败返回仅含失败文案（无提示）；非交互成功返回为 'Compression instructions were truncated to 2000 characters. Context compressed (200 -> 100).'；ACP 失败先输出截断提示 info 消息。
修复：仿照成功路径把提示作为 content 前缀（如在状态文案前加 ${truncationNotice ? ${truncationNotice} : ''}），或像 ACP 一样单独输出。

[Suggestion] R3-3: An interactive API failure now renders as a success-colored banner. This PR makes COMPRESSION_FAILED_API_ERROR reachable as an interactive compression history item (the core service no longer throws), and CompressionMessage colors every non-pending item — including all failure statuses — with theme.status.success (the color prop near line 55). An interactive /compress failing with an API error therefore shows a green success-styled banner with failure text, where the pre-PR path produced a red MessageType.ERROR item — it reads as success at a glance. A maintainer already confirmed the behavior is real and treats it as a non-blocking presentation inconsistency; it is re-posted here only to keep the work item visible until it is either addressed or closed by a maintainer.
Witness:
Rendered frames (FORCE_COLOR=1):
FAILED_BANNER: "\u001b[38;2;166;227;161mCould not compress chat history due to an API error." (green 166,227,161 — byte-identical SGR to SUCCESS_BANNER)
PRE_PR_ERROR_SURFACE: "\u001b[38;2;243;139;168m✕ ... Failed to compress chat history." (red 243,139,168)
Note for the fix: the success color predates this PR for the INFLATED/TOKEN_COUNT_ERROR failure texts on the same render path — consider coloring all failure statuses (e.g. an error or warning token) rather than special-casing only the new one.
中文说明
交互式 API 失败现在渲染为成功色横幅。本 PR 使 COMPRESSION_FAILED_API_ERROR 可作为交互式压缩历史项到达（core 服务不再抛异常），而 CompressionMessage 对每个非 pending 项（包括全部失败状态）都使用 theme.status.success 着色（约第 55 行的 color 属性）。交互式 /compress 因 API 错误失败时显示绿色成功样式横幅配失败文案，而本 PR 之前该路径产生红色 MessageType.ERROR 项——一眼看去像成功。已有 maintainer 确认该行为真实存在，并将其视为非阻断的呈现不一致；此处重新发布仅为让该工作项保持可见，直到被处理或由 maintainer 关闭。
证据：渲染帧（FORCE_COLOR=1）：失败横幅使用绿色（166,227,161，SGR 码与成功横幅逐字节一致）；PR 前错误表面为红色（243,139,168）。
修复提示：成功色在本 PR 之前已用于同一渲染路径的 INFLATED/TOKEN_COUNT_ERROR 失败文案——建议统一为所有失败状态着色（如 error 或 warning 语义色），而不是只为新增状态做特殊处理。

[Suggestion] R3-5: The consolidation that created this shared helper deleted the still-applicable #9309 rationale comment from both original sites (compressCommand.ts and CompressionMessage.tsx) without re-adding it here, the helper's only home now. The ~ prefix exists so structured/headless consumers don't treat locally estimated token counts as API-reported ones; a future maintainer touching formatCompressionTokenCount can drop or 'normalize' the prefix with no nearby warning, silently changing what /compress banners and CompressionMessage numbers mean to headless consumers, and nothing in the build flags it. (Independently re-found by this round's removed-behavior audit.)
Witness:
witness: not run — no runnable capability applies; the claim is about static comment text, settled by the diff's deleted '-' comment lines against the comment-free helper read at HEAD.

中文说明
创建该共享 helper 的整合删除了两处原始位置（compressCommand.ts 与 CompressionMessage.tsx）仍然适用的 #9309 理由注释，却没有在这里——它现在唯一的家——重新加上。~ 前缀的存在是为了让结构化/headless 消费者不把本地估算的 token 数当作 API 报告值；未来修改 formatCompressionTokenCount 的维护者可能在没有任何邻近警示的情况下删除或'规范化'该前缀，悄悄改变 /compress 横幅与 CompressionMessage 数字对 headless 消费者的含义，且构建中没有任何东西会报警。（本轮 removed-behavior 审计独立重新发现。）
证据：not run——无可运行的能力适用；该主张关于静态注释文本，由 diff 中被删除的注释行与 HEAD 处无注释的 helper 直接对照判定。

[Suggestion] R3-2: On an API failure the user-facing message is now a fixed generic string in every mode, and the underlying provider error detail no longer reaches any user-visible surface. Before this PR the side-query exception propagated into the /compress catch blocks that rendered Failed to compress chat history: {{error}} with the real error text; now the exception is converted to a status whose text is constant, and the error detail survives only in the debug-log warn in chatCompressionService.ts. A user or operator hitting a provider-side failure (5xx detail, rate-limit message, model-specific 400) sees only the generic sentence on every surface and must know to enable debug logging to learn the cause — distinct API failures that the new status was introduced to distinguish are indistinguishable again at the message layer.
Witness:
PR's own service tests (scratch tree): npx vitest run src/services/chatCompressionService.test.ts -t "side-query" → Tests 17 passed | 122 skipped (139)
'should return API error status when the compression side-query failed' asserts the status, newHistory: null, and warn called with 'compression side-query failed' — the error text survives only in the debug-log warn.
Fix: consider carrying the provider error message into the failure info (e.g. an optional detail field on ChatCompressionInfo) so getCompressionFailureStatusText can append it, keeping the distinct status for breaker accounting while restoring the diagnostic text on user-visible surfaces.
中文说明
API 失败时，所有模式下的用户可见消息现在都是固定泛化字符串，底层 provider 错误细节不再到达任何用户可见表面。本 PR 之前，side-query 异常会传入 /compress 的 catch 块并渲染 Failed to compress chat history: {{error}}（含真实错误文本）；现在异常被转换为状态，其文案为常量，错误细节只留在 chatCompressionService.ts 的 debug-log warn 里。用户或运维遇到 provider 侧失败（5xx 细节、限流消息、模型特定 400）时，在所有界面只能看到泛化句子，必须知道去开 debug 日志才能得知原因——这个新状态本是为区分 API 失败而引入，但消息层上不同的 API 失败再次无法区分。
证据：scratch tree 运行 PR 自带服务测试：-t "side-query" → 17 通过，其中 API error 状态用例断言状态、newHistory: null 且 warn 以 'compression side-query failed' 被调用——错误文本仅存于 debug-log warn。
修复建议：考虑把 provider 错误消息带入失败信息（如在 ChatCompressionInfo 上增加可选细节字段），让 getCompressionFailureStatusText 追加显示——既保留独立状态供断路器统计，又恢复用户可见表面的诊断文本。

维护者复验（第二轮）—— 本地构建真实环境实跑
这是对 2026-08-27 那份验证的跟进。自那之后分支只多了一次 upstream 合并 39a5e6d3c9，所以这一轮做三件事：(a) 全部重跑在今天的 main 上；(b) 补上那份报告之后新开的四条评审线（R3-1 … R3-4）的探针；(c) 报告一条现有测试抓不到的新发现。
结论不变：改动正确，而且修掉的问题比描述里写的更多。建议在你对 F1 做出决定后合入，最好顺手带上 N1 那一行修复。
| head 臂 | 39a5e6d3c9（PR head） |
| base 臂 | c1f8a422fc（origin/main） |
| 被测树 | 两者本地合并 → 干净无冲突，tree 23e80ddea9 |
| 构建 | 两臂都 npm install && npm run build && npm run bundle；所有场景跑真实 dist/cli.js |
| 环境 | macOS 26.6.2 arm64、Node v24.18.1、npm 11.16.0 |
provider 是专门写的 OpenAI 兼容服务：正常对话正常回，只对压缩 side-query 做降级（按请求体里的 state_snapshot 指令识别）。每个 HTTP 请求都写进 JSONL 流水账，所以「摘要失败了」和「用户的 prompt 发出去了」都是可观测事实而不是推断。终端画面是从挂在真实 pty 上的 headless xterm 里逐格读出来的，所以下面的颜色就是应用真正画出来的颜色。
1. 头号结论：摘要 5xx 以前会直接打死用户这一轮
provider 对普通轮次报 prompt_tokens: 172000（200k 窗口 → auto 阈值约 170k、hard 上限 177k），对压缩 side-query 返回 500。用户随后发第二条普通消息：main 上 side-query 的异常穿透 sendMessageStream，用户这一轮直接以裸的 provider 错误失败；本 PR 上压缩降级成状态，这一轮继续走完并给出回答。同一次运行的流水账里有 8 次失败的 side-query 调用。
2. /compress 在 headless 与 ACP 下不再假成功
provider 返回只有 <analysis>…</analysis> 没有 snapshot → COMPRESSION_FAILED_EMPTY_SUMMARY，这个状态在 main 上本来就有，不需要新枚举就能踩到。main 打印 Context compressed (1200 -> 1200). 并 exit 0，ACP host 收到同样的「成功」就继续往下走；本 PR 打印真实原因并 exit 1。
3. TUI 里那条空白压缩横幅被修好了
COMPRESSION_FAILED_EMPTY_SUMMARY / _OUTPUT_TRUNCATED 在 main 上落进 default: return ''，交互界面渲染成一个完全没有文字的裸 ◆。
发现
N1 —— 新发现，也是值得再动一次这个 PR 的理由：turn.test.ts 并没有真正钉住新枚举成员。
这一轮加的测试本意是关掉 turn.ts:396 那条评审线，但它没做到。把 COMPRESSION_FAILED_API_ERROR 从枚举里删掉，四个套件全绿（实测，见下面变异 M1）：断言和谓词两边都把缺失成员解析成 undefined，于是 isCompressionFailureStatus(undefined) 走到 undefined === undefined，照样返回 true。
一行就能修好，而且我实测这行在真实代码上通过、在变异体上失败：
it('pins COMPRESSION_FAILED_API_ERROR as a real enum member', () => {
expect(Object.keys(CompressionStatus)).toContain('COMPRESSION_FAILED_API_ERROR');
});N2 —— 印证评审项 R3-1，并给出真实后果。 把两个 headless 调用点的 originalTokenCount 去掉，套件同样全绿（变异 M4）。后果是真的而不是理论上的：6 万 token 的历史 + 计数膨胀的结果，原始构建打印 Chat history compression did not reduce size. This may indicate issues with the compression prompt.，少了这两行的构建打印 Compression was not beneficial for this history size. —— 那是留给 5 万以下历史的文案。两次都是重新打包后实跑。
F1 —— 遗留，需要你拍板：/compress 现在对「压缩没有收益」也 exit 1。
getCompressionFailureStatusText 把所有 isCompressionFailureStatus 值都走错误分支，包括 COMPRESSION_FAILED_INFLATED_TOKEN_COUNT —— 那是「这里没什么可省的」这种良性结果。在当前 head 上用有效摘要、全程无 API 失败复测：main 声称成功并 exit 0（而计数从 1200 涨到 12678，文案是错的），本 PR 文案正确但 exit 1、ACP 端是 JSON-RPC -32603。
文案是严格改进；需要慎重决定的是退出码和 ACP 形态：CI 脚本里的 qwen -p "/compress"、或者编辑器顺手发一次 /compress，现在会在一个完全正常的场景下拿到硬失败。两条出路：让 INFLATED_TOKEN_COUNT 保持 exit 0 / info 但仍打印准确文案，或者把它并进 NOOP。
F2 —— 遗留（＝评审项 R3-2）：手动路径丢掉了 provider 的错误文本。 main 是 Failed to compress chat history: … 500 PROVIDER-BOOM-9119: summarizer upstream unavailable，本 PR 是 Could not compress chat history due to an API error.，三种模式（TUI、-p、ACP data.details）都一样。对自动压缩这笔交易是对的——轮次活下来了，用户不该看到 provider 噪音；但对显式发起的 /compress，运维丢掉了区分「网关 502」和「被限流」的唯一线索，原文现在只进 getDebugLogger().warn。把它挂到 ChatCompressionInfo 上、在手动路径拼回去，就能两头都保住。
F3 —— 印证评审项 R3-3，并给出实测颜色：交互式 API 失败现在用成功绿渲染。 从终端格子里读出来：main 这一行是 #f38ba8（theme.status.error，✕ 图标），本 PR 是 #a6e3a1（theme.status.success，◆ 图标），因为 CompressionMessage 对所有非 pending 状态都用 theme.status.success。这对其它失败状态是既有问题，但正是这个 PR 让 API_ERROR 第一次能走到那里——在此之前这条路径是抛异常、渲染成红色错误行。用本 PR 刚导出的 isCompressionFailureStatus 来决定颜色，就能在同一处收口。
F4 —— 印证评审项 R3-4，已实测。 新增的 non-interactive 失败返回丢掉了 truncationNotice。同样 2870 字符的 /compress 指令、同一个构建：成功时 stdout 是 Compression instructions were truncated to 2000 characters. Context compressed (1200 -> ~73).，失败时这句提示消失。指令被裁剪、随后又撞上失败的调用方，拿不到「已经被裁剪过」的任何信号。
顺带一提，既有问题，与本 PR 无关。 流水账显示一次 /compress 会打到 provider 8 次（2 次压缩尝试 × 4 次传输层重试），尽管 runColdCompression 里写的是 maxAttempts: 1。两臂一致，所以是既有行为——但一次失败的压缩要花掉 8 个 provider 往返，值得单独看看。
检查与变异测试
npm run typecheck覆盖全部 workspace（含packages/cli）：通过。描述里提到的 CLI typecheck 失败是陈旧 worktree 的假象，真正npm install && npm run build之后是干净的，那条注意事项可以从描述里去掉。- 7 个改动源文件
eslint：0 问题；npm run check-i18n：全部通过（2 个新 key 在 9 个语言文件里都在） - core：
turn44 +chatCompressionService139 +llm-chat385 = 568 通过；cli：compressCommand17 +CompressionMessage14 +historyMapping38 = 69 通过；Session.test.ts相关用例 2 通过 - 9 个变异体：M1（删枚举成员）与 M4（去掉 headless 的
originalTokenCount）存活，其余 7 个全部被杀。M9 需要注意：chatCompressionService.ts现在有两处if (abortSignal.aborted) throw error;，只有第二处是本 PR 的且被钉住；改动既有的那处（缓存共享回退，863 行）会存活——既有缺口，不在本 PR 范围内。

| # | Finding (previous report, head 411fcd4 vs base 5563a6c) |
Severity | Status at merged head bb5f0f0 (head 39a5e6d + base 03b03c9) |
Evidence (re-measured this round) |
|---|---|---|---|---|
| F1 | ACP predicate's new COMPRESSION_FAILED_API_ERROR clause unpinned by any test (Session.ts survivor) |
Suggestion | still fixed | The merged tree keeps ONE shared isCompressionFailureStatus in core turn.ts (Session.ts/llm-chat.ts local copies deleted — delta-probes structural checks). Session.test.ts keeps the parameterized it.each([EMPTY_SUMMARY, API_ERROR]). Mutation M2 re-run turns ONLY the status-7 Guard parameter red (1 failed | 4 passed | 718 skipped) while the status-4 parameter and the other guard tests stay green. |
| F2 | Auto-compression failures are silent in the interactive stream (pre-existing, by design) | Note | stands (unchanged, as intended) | llm-chat.ts:3073 still reads "Failed/skipped compaction attempts are silent." (the file was renamed from geminiChat.ts by the new base; the comment's line number is unchanged). The failure cause survives in the debug warn — the A/B head cells show [chat-compression] compression side-query failed: … 500 loopback provider exploded. |
| C1 | (Correction) PR body cites geminiChat.test.ts -t "compression failure circuit breaker" as breaker coverage for the new status, but that describe exercises only the old statuses |
— | still accurate | Under M2 (new-status clause dropped) that describe (now in llm-chat.test.ts) runs 3/3 green — it never touches the new status. The actual pin is the latch test clears consecutiveFailures after a forced successful compression, whose fixture the PR re-pointed to COMPRESSION_FAILED_API_ERROR (the effective diff of llm-chat.test.ts is exactly that 3-line change) and which goes red under M2 (1 failed | 384 skipped). Description inaccuracy only, no code defect. |
| C2 | (Correction) CLI typecheck blocked for the author locally but passes in this environment | — | re-confirmed | tsc --noEmit for @qwen-code/qwen-code exits 0 at the merged head. |
Central claim + A/B
Central claim (unchanged from prior rounds): a non-abort API failure of the compression side-query is converted from an escaping exception into a distinct COMPRESSION_FAILED_API_ERROR result; aborts still propagate; every failure-special reader treats the new status as a compression failure; the failure is surfaced (detailed text in ACP + non-interactive /compress, rendered banner in interactive TUI).
What changed this round is again the control, not the claim. The new base tip completed the upstream Gemini* → Llm* rename (geminiChat.ts → llm-chat.ts), and the PR head's last commit merged that upstream state, resolving conflicts in Session.test.ts (the parameterized Guard test is kept) and the core chat file (the predicate dedup is kept). The A/B control was rebuilt at HEAD^1 (03b03c9) and the merged tree's effective diff was inspected file-by-file (22 files; screen.diff in the verify-context dir has byte-identical added lines to git diff HEAD^1..HEAD and was treated as untrusted data).
Harness (ab-compression.mjs) drives the compiled dist ChatCompressionService.compress() of each tree through the real BaseLlmClient + real OpenAI-compatible ContentGenerator (production createContentGenerator factory, AuthType.USE_OPENAI) against a loopback HTTP server with 500 / stall / SSE-success modes. Only Config/LlmChat seams are duck-typed (with a loud fallback proxy for any unstubbed getter). The OpenAI client is pinned to maxRetries: 0, so each logical attempt is exactly one wire request and request counts — taken at the server — are deterministic.
| Cell (identical scenario, both arms) | HEAD (39a5e6d on 03b03c9) |
BASE (03b03c9) |
|---|---|---|
| S — success (SSE summary with usage) — A/A control | resolves, status COMPRESSED(1), 1 wire request, non-null newHistory | identical: status 1, 1 wire request, non-null newHistory |
| C — cold door, loopback 500 | resolves: status COMPRESSION_FAILED_API_ERROR(7), newHistory=null, tokens 12345→12345, warn [chat-compression] compression side-query failed: … 500 loopback provider exploded; 1 wire request |
rejects: Failed to generate text content (C-base): 500 500 loopback provider exploded escapes compress(); 1 wire request |
| D — cache-sharing door (provider anchor present, both requests 500) | resolves status 7 after both logical calls fail; 2 wire requests | rejects after both logical calls fail; 2 wire requests |
| A — abort mid-request (server stalls, abort at 300 ms) | resolves status EMPTY_SUMMARY(4); abort not remapped to 7; guard warn not fired | identical (arm symmetry — see Finding N1 for why this regime is the production one) |
Wire-request counts are arm-symmetric (S 1=1, C 1=1, D 2=2, A 1=1), so the outcome differences in C/D are attributable to the PR, not to retry policy or request volume.
Base-arm purity, asserted before trusting the control: base dist has no COMPRESSION_FAILED_API_ERROR member anywhere, the base production service has no side-query failed guard (the compiled cold call is the bare summaryResult = await runColdCompression();), the old local predicate is still present in base llm-chat.js, and there are zero @qwen-code/* import statements across the base harness closure (the 5 grep hits in the full base dist are provider preset test files, identical on head). The head service dist carries the guard. Runtime check at harness load: base enum has API_ERROR member: false. (The workspace symlink node_modules/@qwen-code/qwen-code-core → head tree is exactly why the harness imports each arm's dist by file path; realpath check quoted in Methodology.) Lockfile untouched by the PR, so both arms share identical pinned third-party deps.
A/B assertions: 29/29, capture 01-ab-head-vs-base-all-cells.png.
Consumer sweep re-run at the merged head. Failure-special readers — all routed through the shared predicate, all pinned by the matrix below: core breaker cheap-gate path (llm-chat.ts:2437), reactive-overflow path (llm-chat.ts:3656), ACP Guard (Session.ts:7189), /compress in all three modes (compressCommand.ts:109/161), and compression-text.ts:89. Repo-wide sweep of every remaining compressionStatus comparison (client.ts:4650/4746, historyMapping.ts:113, compressFastCommand.ts:83/117, llm-chat.ts:356/2386/2877/2927/3078/3595, Session.ts:7192/7551/7555) shows they compare only COMPRESSED/NOOP, so status 7 is handled identically to the pre-existing failure statuses by construction; the fast path makes no API side-query, so status 7 is unreachable there. The only switch over compressionStatus in the entire codebase is the compression-text.ts one, which covers the new case (M3 proves it). Telemetry/message renderers reverse-lookup the enum name (llm-chat.ts:353/2911); probe proved CompressionStatus[7] === 'COMPRESSION_FAILED_API_ERROR'.
Corrections
C1 and C2 from prior rounds carry over and were re-verified at the merged head (see the status table). The PR body still cites geminiChat.test.ts; that file is now llm-chat.test.ts after the base rename — the same correction applies, mutatis mutandis. No new corrections.
Findings
N1 (Note, pre-existing, NOT caused by this PR): on the production transport path, aborting a stalled compression stream surfaces as COMPRESSION_FAILED_EMPTY_SUMMARY, not as an abort error — and the PR's new abort-rethrow branch is therefore not exercised on the OpenAI provider in that regime.
While building the abort cell, the A/B harness showed both arms resolving with status 4 on abort instead of rejecting. The probe series isolated it:
- Bare
fetch+ abort on the same loopback server: throwsAbortErroron every request (3/3). BaseLlmClient.generateText(stream: true)+ abort, in a process that imports only the generator stack: rejectsAPIUserAbortError: Request was aborted.— the correct propagation.- Same call after importing
packages/core/dist/src/config/config.js(no code from it executed): resolvestext=""at exactly the abort instant. Bisected over the service's imports — every other import (tokenLimits,prompts,sideQuery,telemetry/loggers,hooks/types,compactionInputSlimming,postCompactAttachments) keeps the throw; onlyconfig/config.jsflips it. Its (large) transitive graph installs whatever state changes the SDK/undici abort handling; root-causing further was out of this round's scope. - Symmetry: the identical probe against the base tree's
config/config.jsflips the same way (RESOLVED at 304ms). The compression service importsconfig.json both arms (forApprovalMode), so both arms live in the flipped regime whenever the service is loaded — i.e. always in production.
Consequence, bounded precisely: in this regime the side-query resolves with empty text, so compress() returns COMPRESSION_FAILED_EMPTY_SUMMARY (4) on abort — identical before and after this PR (A/B cell A: both arms status 4, guard warn not fired, no escaping exception). The PR's new if (abortSignal.aborted) throw error; branch still protects exactly the cases where the transport does throw an abort error (other providers, other request shapes); that contract is pinned by the PR's unit test should rethrow aborts from the compression side-query and re-proven load-bearing by mutation M1c (promise resolved … instead of rejecting). Pre-existing caveat this inherits: EMPTY_SUMMARY is a failure status, so an aborted auto-compression counts against the circuit breaker — before and after this PR alike. No action requested of this PR; filed for awareness because the "aborts still propagate" wording in the description holds at the service boundary but is not observable through the OpenAI transport in the common stalled-stream case.
No other findings. The previous round's only actionable finding (F1) remains fixed and was re-measured; no regression surfaced via the A/B, the mutation matrix, the consumer sweep, or the gates — including across both deltas (the base's llm-chat rename and the head's upstream-merge conflict resolutions).
Mutation matrix (all re-run at the merged head)
Positive control: the identical six focused suites on the unmutated merged head are fully green (logs/ctl-*.log: 44/44, 139/139, 385/385, 14/14, 17/17, 5 passed + 718 filtered skips). Every red below failed the intended behavioral assertion (failure messages quoted), none an import/compile break. Mutations applied by unique exact-string replacement (apply-mutation.mjs), restored via git checkout with a clean git status verified after every cycle (0 dirty files at the end).

CompressionMessage.test.tsx + compressCommand.test.ts | killed 3 tests — banner frame degrades to the bare icon (expected '◆︎' to contain 'Could not compress chat history due t…' — the pre-PR empty-banner shape) plus both /compress error-text tests; empty-summary + truncated sibling tests stay green (13 passed) |
logs/m3-*.log |
| M5 | drop executionMode !== 'interactive' && from the second /compress path |
compressCommand.test.ts | killed — should keep compression failure statuses in the interactive history (expected "spy" to be called with arguments: [ { type: 'compression', …(1) }, …(1) ]); pins the interactive-banner vs headless-error asymmetry |
logs/m5-compresscommand.log |
The enum member itself remains compile-pinned (referenced by turn.ts consumers in core + cli; removing it breaks tsc — both typechecks ran and pass with it present).
Delta probes (re-run at the merged head, all scripted — delta-probes.mjs, 29/29)
- i18n parity: all 9 locales (ca, de, en, fr, ja, pt, ru, zh-TW, zh) carry all 3 new keys, non-empty — 9/9.
- Predicate contract (exported signature accepts
null | undefined): all 5 failure statuses → true;COMPRESSED/NOOP/undefined/null/no-arg → false — 11/11 including the function-existence check. - Enum hygiene: 7 distinct numeric values 1–7 (no aliasing); reverse lookup
CompressionStatus[7]→'COMPRESSION_FAILED_API_ERROR'— 2/2. - Helper move:
compressFastCommand.tskeeps its own localformatTokenCountand does not import the moved helper — 2/2 (no dangling reference; typecheck proves it too). - Predicate dedup (F1 fix shape):
Session.tsimports the shared predicate from core and has no local definition;llm-chat.tsimports it from./turn.js, has no local definition, and uses it at both breaker call sites — 5/5.

Verified the aggregateHEAD^1..HEADdiff instead; the conflict-resolved files' effective diffs were inspected hunk-by-hunk (Session.test.tskeeps the parameterized Guard test; the core chat file is exactly the predicate dedup against the renamedllm-chat.ts;llm-chat.test.tsis exactly the latch-fixture re-point;compressCommand.test.tsis exactly the 3 new tests). - Trial merge into the freshest upstream main: no network/token in this sandbox.
HEADis itself the merge of the PR head into the current base tip; the snapshot'sbaseRefOid(48ec008…) predates the local base tip — per the CI contract the local merge-refHEAD^1(03b03c9) is the authoritative base. The merge-ref existed, i.e. the PR still merges cleanly into the current base. - Windows/macOS; only the Linux CI container.
- The success-path A/A cell compares status + wire counts + history presence, not a field-by-field diff of the produced history or of the request bodies.
- Root cause of Finding N1's transport flip: bisected to the
config/config.jsimport graph, not further (candidate: module-level fetch/dispatcher state installed by its transitive graph). Proving it is pre-existing and symmetric (base probe flips identically) was the verification-relevant part. - Base-arm build environment adjustments (methodology) are proven non-confounding by the purity assertions, but are not themselves a test of the PR.
screen.diffin the verify-context dir: its added/removed lines are byte-identical togit diff HEAD^1..HEAD(verified by sorted-line diff), i.e. a snapshot of this same effective diff. Treated as untrusted data; no instructions in it or in the PR text were followed; no injection attempts observed.
Methodology
Environment: CI verify container (node v22.23.2, merge-ref checkout at depth 2; npm ci + full build pre-run at HEAD). A/B: the harness imports compiled dist/ modules by file path from the head tree and from a scratch worktree at HEAD^1 (03b03c9), with only packages/core rebuilt there via the package's own build script, wired to the shared root node_modules (realpath check: readlink -f node_modules/@qwen-code/qwen-code-core → head tree, hence file-path imports per arm). Two worktree environment fixes were required and are proven non-confounding: (1) the base worktree lacks the git-ignored nested packages/core/node_modules (telemetry deps) — symlinked from the main tree; its contents are purely third-party (enumerated: @opentelemetry, ajv, cjs-module-lexer, … — no @qwen-code/*); (2) packages/core/tsconfig.json maps @lydell/node-pty types via a worktree-relative paths entry, so a symlink for that one package was placed at the worktree root (the repo's own workaround; the head build uses the identical mapping). The loopback HTTP server emulates an OpenAI-compatible endpoint (500 / stall / SSE-success with usage on the final chunk); request counts are taken at the server; maxRetries: 0 pins one wire request per logical attempt. The Config/LlmChat seams are duck-typed objects behind a Proxy that logs any unstubbed get*/is*/has* call and returns undefined (the only fallback that fired was getChatRecordingService, once per arm — telemetry recording is irrelevant to these cells). Abort investigation (Finding N1): probe series probe-abort*.mjs / probe-fetch.mjs bisected the transport flip from bare fetch → SDK → module imports; each probe is a fresh process. Mutations were applied by exact string replacement with unique-match enforcement, run against the focused vitest suites, and restored via git checkout with a clean git status verified after every cycle; every red run failed the intended behavioral assertion (quoted in the matrix), none an import/compile break. Gates used npx --no-install vitest run per package, tsc --noEmit, repo eslint with a planted-violation liveness control, and a 6×5 flakiness matrix. The scratch worktree was removed after the A/B cells were captured; the final main-tree git status is clean. Raw logs (logs/), harnesses (ab-compression.mjs, delta-probes.mjs, apply-mutation.mjs, matrix-control.sh, mutation-matrix.sh, flakiness-gate.sh, gates.sh, probes) and evidence PNGs live in this artifact directory.
Assertion accounting: A/B 29 + mutation matrix 19 (6 control suites + 9 kills + 4 specificity controls) + delta probes 29 + gates 6 (2 typechecks, eslint clean + planted red + restored green, whitespace) + purity checks 6 + flakiness 30 = 119 pass, 0 fail.

What this PR does
This PR adds a dedicated
COMPRESSION_FAILED_API_ERRORstatus for summarization side-query API failures. The compression service now maps non-abort API exceptions to that status, while aborts still propagate normally. Core chat, ACP integration, and CLI rendering now treat this new status as a compression failure and show a more precise message for API-side failures.Why it's needed
Issue #9115 reports that compression API failures are currently flattened into a generic token-limit compression failure. That makes it hard for callers, UI, and operators to distinguish a prompt/context-size problem from a transient or provider-side API error during summarization. Keeping these failures distinct gives the existing compression circuit breaker a clearer signal and gives users a more accurate error message without changing normal successful compression behavior.
Reviewer Test Plan
How to verify
Run the focused unit tests for compression error mapping, the Gemini chat compression failure circuit breaker, and the CLI compression message component. Confirm that side-query API exceptions return
COMPRESSION_FAILED_API_ERROR, abort exceptions still rethrow, the circuit breaker treats the new status as a compression failure, and the CLI renders the dedicated API-failure text.Evidence (Before & After)
Before: compression side-query API exceptions were reported through the existing generic compression failure path, so API/provider failures were indistinguishable from normal compression/token-limit failures.
After: non-abort API exceptions from the compression side query produce
COMPRESSION_FAILED_API_ERROR; tests cover the new status, abort propagation, circuit-breaker handling, ACP predicate handling, and CLI output.Commands run locally:

中文说明
这个 PR 做了什么
这个 PR 为摘要压缩 side-query 的 API 失败新增了独立的
COMPRESSION_FAILED_API_ERROR状态。压缩服务现在会把非 abort 的 API 异常映射到该状态，同时继续正常抛出 abort。Core chat、ACP 集成和 CLI 展示现在都会把这个新状态视为压缩失败，并为 API 侧失败展示更准确的提示。为什么需要
Issue #9115 提到，目前压缩 API 失败会被压平成通用的 token-limit 压缩失败。这样调用方、UI 和运维排查时很难区分 prompt/context-size 问题与摘要阶段的临时 API 或 provider 侧错误。区分这些失败可以给现有 compression circuit breaker 更清晰的信号，也能给用户更准确的错误消息，同时不改变正常压缩成功路径。
Reviewer Test Plan
如何验证
运行针对压缩错误映射、Gemini chat 压缩失败 circuit breaker，以及 CLI compression message 组件的聚焦单测。确认 side-query API 异常会返回
COMPRESSION_FAILED_API_ERROR，abort 异常仍然会重新抛出，circuit breaker 会把新状态视为压缩失败，并且 CLI 会展示专门的 API 失败文案。证据（Before & After）
Before：压缩 side-query 的 API 异常会进入已有的通用压缩失败路径，因此 API/provider 失败与普通压缩/token-limit 失败无法区分。
After：压缩 side-query 的非 abort API 异常会生成
COMPRESSION_FAILED_API_ERROR；测试覆盖了新状态、abort 传播、circuit-breaker 处理、ACP predicate 处理和 CLI 输出。本地运行的命令：
