Exact-head delta review of 7fef24cdfe0369e6abf4eb129e6e10cf57d17c88: changes requested. Post-KILL pipe reclamation and unresolved terminal suppression improved, but two P2s remain.
- Cleanup accounting does not bound spawned harnesses. Capacity is acquired only inside
terminate(), after spawn. A null lease changes the eventual response but does not prevent new work. Quarantine eviction and the 120-second TTL also release accounting for still-live survivors. Reserve capacity before spawn, retain it until confirmed exit, and refuse new turns when unresolved survivors exhaust the bound. - Parent exit during the KILL window can still become false tree success. Tree failure is recorded only when the parent was already gone before signaling. If TERM/KILL tree signaling fails, the parent then exits after direct KILL while a descendant retains pipes, final classification becomes
pipes-heldandallExited=true. Preserve independent tree uncertainty regardless of parent-exit timing; quarantine must not clear it merely because local pipes later close.
Coverage remains insufficient: the cancellation test supplies no abort signal and the finite fake completes normally; descendant/Windows cases are only EventEmitter/injected results; no capacity exhaustion, TTL, eviction, or real Windows/descendant regression proves the resource bound.
The PR remains draft; exact workflows are action-required and dependency sponsorship/provenance is still separate. No security scan was run.

Exact-head re-review of defa575e1a08f9bad2dc048b2ab104451a050f8a: capacity-before-spawn, retained TTL accounting, tree-signal failure tracking, real cancellation, and the POSIX descendant regression materially improve the prior design. One P2 remains.
Local pipe reclamation can release capacity while an unresolved descendant survives. deliverExit() releases the lease unconditionally when the direct child emits close. In the failed-tree/dead-parent path, destroying local pipes can produce that parent close without terminating the descendant. The lease is then released and quarantine sweeping drops the entry because child.closed is true.
Keep unresolved-tree ownership independent of direct-parent/stdio closure and retain the lease until tree termination is established. Add a regression where pipe reclamation causes parent close while the descendant stays alive. Current fakes do not model that relationship, and the new real-process regression explicitly skips Windows.
Retain CHANGES_REQUESTED until this final resource-accounting path and real Windows ownership evidence are addressed. No security scan was run.

Exact-head review of d43e68f: the new tree-ownership latch fixes the previously reported already-exited, pipe-reclaim, then close path. One P2 interleaving remains.
Tree ownership is latched only when the settlement reason is unresolved-tree. If process-tree signaling failed but the direct parent is still running at the deadline, the child is classified running, not latched. The ladder then reclaims its pipes; when that parent exits later, deliverExit releases the teardown lease, and the next quarantine sweep drops the closed handle even though an unreachable descendant can still be alive.
Preserve tree uncertainty independently from the direct parent running/exited label whenever tree delivery failed. Add a regression for tree signal failure, parent running at the deadline, pipe reclamation, later parent close, and a still-live descendant; the lease must remain held until the platform proves the tree empty. The current late-close test expects unconditional release with tree signaling disabled and does not probe this survivor.
Real Windows descendant evidence and the dependency provenance/sponsorship decision remain separate holds. No security scan was run.

P3 documentation follow-up on the same exact head: sdk-turn.ts around lines 271-273 still says unobservable quarantine entries are dropped, while the new design intentionally retains ownership/capacity past the age warning until tree settlement.

…configs `claude-cli` shipped in 2.65.0 and named the transport the row used to be: a hand-built `claude -p` turn. The row is moving onto Anthropic's Claude Agent SDK — the harness behind the Claude Code CLI — and the old name also collided with `src/providers/claude-cli-identity.ts`, which forges a `claude-cli/<ver>` user agent for the Messages-API rows. The registry row, the adapter key and the adapter module are renamed. `claude-cli` keeps resolving through `DEPRECATED_PROVIDER_ALIASES`, and `claude-provider-rename-migration` moves the saved row, an explicit adapter string on a custom-named row, and every cross-config reference shape the shared rewriter owns; it refuses with a warning when the destination key is already taken or a keyed map collides, because two rows can describe two different sign-ins. The new projection runs first in the shared startup pass so later repairs see the canonical id. Docs, the structure map and the test layout follow the rename; `tests/claude-integration/` keeps its `claude-cli` file, which pins the CLI client path, not this provider.
The row spends a Claude subscription on a client that is not Claude Code, which is the traffic Anthropic suspended accounts over when it banned consumer OAuth in third-party apps. The registry comment and the user-visible `note` framed that as "Anthropic's call, flagged for maintainer review", which reads like a supported path with a footnote. Both now say what it is: against the terms, enforceable, and the loss lands on the signed-in account rather than on OpenCodex. The provider guide opens the section with the same warning instead of closing it with a remark, and the adapter doc names the two routes that do not depend on that reading — `anthropic-apikey` for automated clients, `ocx claude` where the genuine CLI is the client.
What we shipped in 2.65.0 was against Anthropic's terms: an OpenCodex-made one-shot `claude -p` turn with the caller's prompt replacing the harness prompt, no session and the harness tools stripped, driven by a client that is not Claude Code. A Claude subscription is licensed for Anthropic's own harnesses, and that construction spent it as an API behind a thin CLI veneer for a third-party agent loop, which is the usage accounts get suspended over. Meridian's route is safer because the harness runs the turn, and this row is the correction that takes it. That is not the same as clean, and the text now says so: the client is still not Claude Code, so the row stays a grey area, and `anthropic-apikey` is the only route without an interpretation question. The previous wording made who makes the request the criterion, which reads as an argument for a row that instead has to say what it was and what changed. The registry comment, the row's user-visible `note`, the provider guide (warning at the head of the section, terms remark at its end) and the structure map now carry the chain in plain language.
`src/providers/registry.ts` sits at a 232-line ratchet cap, and the renamed-id resolver the `claude-agent-sdk` row needs pushed it to 251 — `file-size ratchet: repository` fails for this branch and for every branch cut from `dev` afterwards. Caps only move down, so the remedy is a move: the alias table and `resolveDeprecatedProviderId` now live in `src/providers/deprecated-provider-aliases.ts`, which `getProviderRegistryEntry` imports. The comment above `mergeRegistryStaticHeaders` is re-wrapped onto one line less for the same reason, word for word otherwise. The table keeps its rationale: three paths read a retired id outside the rename projection (an early config read, `ocx provider test claude-cli` typed by hand, and a row the projection refused to move).
…luded The adapter no longer builds a `claude -p` command. It calls the Claude Agent SDK's `query()`, which is what this row was supposed to be from the start: the harness keeps its own preset with the caller's instructions APPENDED, the turn is the harness's session, and the client's tool catalog is served by an in-process MCP server (`type: "sdk"`) that advertises the request's own JSON Schema, captures calls and never answers one. Built-in tools stay off, no setting source is loaded, and `persistSession: false` keeps another client's conversation out of the operator's `~/.claude` transcripts. Nothing travels through argv any more — no staged prompt file, no `--mcp-config` path, no second executable. The ToS chain the docs state is now the code's shape, not an intention: the harness does the work instead of being driven by a foreign client, which is Meridian's route. It is still a grey area, and the registry comment, the row's `note`, the provider guide and the structure map say so. Dependency: `@anthropic-ai/claude-agent-sdk` plus its platform package — the Claude Code build it drives, ~230 MB unpacked, the same binary the `claude` npm package installs. Its peer dependencies (`@modelcontextprotocol/sdk`, `zod`) are already runtime dependencies here. Compiled binaries cannot resolve that package path from inside `$bunfs`, so they drive the `claude` on PATH instead and report `cli_not_found` when it is missing; the guide documents both paths. Flagged for security review in the PR description. Shared: `TOOL_BRIDGE_SYSTEM_PROMPT` moved to `coding-agent/tool-bridge-directive.ts` so CodeBuddy and this row cannot describe the bridge differently. The catalog validation, aliasing and name mapping are CodeBuddy's builder, reused on purpose. The bridge contract (init handshake before any call, exact catalog names, per-turn call cap, `tool_choice` and incomplete-call fail-closed) is enforced in both runners, deliberately parallel to `coding-agent/turn.ts`. Verification: `bun run typecheck` clean; 35 tests in `tests/providers/claude-agent-sdk-adapter.test.ts`; focused set 136 pass; `bun test tests/providers` compared against a pristine `origin/dev` control worktree — the same failures, none new; `structure:check`, `privacy:scan` and the file-size ratchet green.
The transport itself is unchanged; these are the defects the first review round found around it. - The retired adapter id keeps resolving. A refused projection (destination row taken, or a colliding keyed map) leaves a saved row saying adapter: "claude-cli", and the adapter it named no longer exists, so `getAdapterDefinition` now reads the same deprecation table the provider-id lookup uses instead of throwing "Unknown adapter". - Only the row the retired preset seeded is renamed. A row that carries the retired NAME on another adapter is the operator's own provider: the projection leaves it, its transport, its billing and every reference to it untouched, and says so in a warning. - The harness runs in an empty per-turn scratch directory instead of process.cwd(): the claude_code preset reports its working directory and a git-status summary to the model, which is the proxy's own tree rather than anything the client sent. The directory is removed once the harness is gone, and a directory that cannot be created fails the turn instead of falling back. - @anthropic-ai/claude-agent-sdk moves to optionalDependencies: it carries the Claude Code build it drives (~230 MB unpacked per platform), an install that omits optional dependencies should not have to carry it, and the missing package already has its own failure path (claude_agent_sdk_unavailable). Live against the signed-in subscription: text and tool turns still answer (3.5 s for the tool turn, zero orphan harness processes), the scratch directory is gone afterwards, and no lease on it survives the turn.
…l tracking The lidge-jun#5945 change on dev replaced the coding-agent parse state single open-call slot (`openToolCallId`) with per-block buffering (`openToolBlocks`, `toolBlockStarts`), so a tool_use block is emitted when it closes rather than when it starts. The adapter completeness invariants compared the starts it had already emitted against the completed count. Under the new state those two are equal by construction, so a block that opened and never closed became invisible and the turn ended as a successful text completion instead of failing closed. That is the regression the existing test, "a result that arrives while a captured call is still open fails closed", caught on the rebase. Both call sites now read `toolBlockStarts` against `completedToolCalls`, the same pair the sibling CodeBuddy turn reads, and the state initializer matches that turn as well. A second test pins the parallel batch the invariant depends on: two calls on one reused block index arrive as two complete calls, in order.
…ge-jun#6022 dev's lidge-jun#6022 hardened the coding-agent capture path and moved the per-turn tool-call limit from the emitted tool_call_start to the block open, because the parser buffers a block until its stop. This adapter reads the same parse state through its own capture-only bridge, so both halves had to follow. The state now sets strictToolBlockCapture for a turn with a bridge, which is what makes the parser refuse incomplete JSON arguments, refuse a delta that belongs to no open block, and treat a same-index start as an implicit stop only once the previous arguments are complete. The cap is checked when toolBlockStarts grows instead of when the buffered start is finally emitted, so a stream that only opens blocks is bounded at the open rather than after it parks. The added test opens more blocks than the cap allows without closing one: without the move it ran on to message_stop and failed there for a different reason.
dev's lidge-jun#6081/lidge-jun#6083 moved the ceiling and the budget for coding-agent tool state into the shared parser, which is the same state this adapter reads through its capture-only bridge. Two halves had to follow, the same class as lidge-jun#6022 and lidge-jun#5945 before them. The parser now enforces its ceiling (16 starts, or a bridge's tighter limit) before it allocates the block and reports the refusal through `toolCallLimitExceeded`; the parse state carries the bridge's limit for that. This adapter only compared `toolBlockStarts` after the fact, so a start the parser refused before allocation left no trace: the dropped call never entered `toolBlockStarts`, the completeness invariants therefore saw starts and completions as equal, and a turn could end as a successful completion with a call missing. The parser also charges retained tool identity and argument fragments to the request's translator budget and releases them on close, EOF, protocol error and abort. The state now carries `incoming.translatorBudget`, `releaseOpenToolBlocks(state)` runs on every exit path, and a budget overflow keeps its own `translation_buffer_limit` code instead of being flattened into the generic SDK error the surrounding branch reports. Two tests cover it: a turn without a bridge that passes the shared ceiling fails closed, and a retained argument past a small per-call budget surfaces the budget's code. Reverting the adapter fails four tests, those two and the two that pinned the cap before, and the existing cap tests now pass through the parser's own admission rather than a parallel count.
…ytes The review found the 8 KiB stderr bound bypassable by one large callback chunk. The sink compared the previously accumulated length and then pushed the whole incoming chunk, so a single oversized chunk was retained in full, and the join happened before the cut, which then cut code units rather than bytes: 8 KiB of three-byte characters left the error message at three times the advertised bound. The sink now charges each chunk against the remaining byte budget at ingestion and keeps only a byte-exact prefix, reusing retainedUtf8Bytes/truncateRetainedUtf8 from src/lib/admission.ts — the helpers the codex diagnostics already use, cut marker included. The join keeps a byte-exact bound as the second line. The regression feeds one 8 KiB chunk of three-byte characters: the message has to stay within the bound and mark the cut. Without the fix it is 24 KiB and carries no marker. Also pinned @anthropic-ai/claude-agent-sdk to the reviewed 0.3.282 rather than ^0.3.282, which leaves the resolved tree unchanged (bun install reports no change), and dropped the trailing blank line at EOF in the provider migration that git diff --check flagged.
query.return() only proves that the SDK's cleanup returned. In the pinned Agent SDK 0.3.282, Query.performCleanup waits at most 2000 ms for the transport exit, while ProcessTransport.close schedules SIGTERM 2000 ms out and SIGKILL 5000 ms after that, both timers unref'd. A TERM-resistant harness is therefore still running when the turn removes its scratch cwd and answers the client, and repeated cancellations accumulate expensive harnesses with live pipes. The turn now spawns the harness itself through spawnClaudeCodeProcess and tears it down on a bounded TERM -> grace -> KILL ladder that awaits the child's close. The scratch directory is removed and the request released only after that, so the next turn does not start on top of a harness that is still alive. Taking the spawn over has a second half that is easy to miss: ProcessTransport.spawnLocalProcess is the only place in the bundle that reads the child's stderr into Options.stderr, and the only place that reports the process exit. Replacing it without reproducing both would have silenced the harness's stderr evidence the previous round fixed. harness-process.ts reproduces the pump (StringDecoder, so a chunk boundary cannot corrupt multi-byte text) and carries the exit, and the one message that reports a dead harness keeps its stderr from this turn's own sink instead of the SDK tail that a custom spawner can no longer fill. Regressions: a TERM-resistant harness is killed and awaited before the cwd goes, and the harness's stderr still reaches the failing turn through the owned pipe. Both fail on the pre-fix head.
Both P2s from the review of 152eb0c are the same question asked twice: what a turn may claim once the harness is out of sight. The terminal frame was emitted from inside the event loop, while query.return() and the reap ladder ran afterwards. The bridge closes the response body on that frame and the body's EOF is what releases the global turn-admission lease, so a client could see completion - and start another admitted turn - while a TERM-resistant harness was still being reaped. Terminal frames are now held and delivered only after harness.terminate() accounts for the process. The SDK's own teardown waits 2000 ms before it even schedules SIGTERM, so the ladder runs first and the SDK is left to unwind on a process that is already gone: the guarantee no longer bills the client for a clock that is not about the process. Deferred behind the SDK clock instead, a tool turn cost 2.0-4.6 s more; with the ladder first it measures 1.8-2.1 s, the range it had before. The second finding: close is not the same event as "the process ended". A launcher hands its pipes to a descendant, the harness ends, the pipe stays open and close is never delivered - so the ladder waited out both ceilings and reported an unresolved teardown as a confirmed exit. exit and close are tracked apart now, a drain that cannot finish on its own has its stdio reclaimed, the process tree is signalled where the platform supports it (process group on POSIX, taskkill /T /F on Windows, the terminator the spawned-CLI turn already uses), a refused signal is recorded instead of ignored, and terminate() returns {confirmed, allExited, unresolved} instead of void. The turn deletes its scratch cwd only on allExited and names an unconfirmed teardown on the warning channel rather than rounding it to "gone". Reclaiming the pipes also ends the wait the withheld close caused inside the SDK. Regressions: an exit with an inherited pipe is reclaimed and reported as pipes-held; a refused signal is reported as a running child with signalFailed; a harness that survives the whole ladder is named as still running; an unresolved teardown keeps the scratch cwd and warns; and the response body - with the admission it releases - waits for the owned harness, driven through the real bridge and the real admission tracker rather than through await adapter.runTurn(). All five fail on 152eb0c with the tests kept. Verified: 49/49 in the adapter file (42 before), typecheck, structure:check, privacy:scan, the file-size ratchet and git diff --check clean; proxy E2E over /v1/messages (text 200/1.94 s pong, tool 200/2.10 s and 200/1.84 s tool_use echo) with no unconfirmed-cleanup warning, no unhandled/EPIPE line, no leftover scratch directory and no leftover harness process. A broader focused run (tests/adapters, tests/ci-workflows, the changed provider file) reports 3837 pass / 3 skip / 123 fail, the same totals as before the change and none of them in the changed area.
The re-review of 3794132 asked for two more things and both hold in the code. The direct parent is not the tree. A launcher can exit while a descendant keeps the inherited pipes, and terminate() read that as settled: the KILL pass skipped every child that had already exited, the handles were reclaimed, allExited stayed true and the scratch cwd was deleted underneath a descendant that may still have been running against it. The KILL pass now covers every child that has not closed - a POSIX group signal and taskkill /T both still reach a descendant whose parent is gone - the handles are taken back after both observation windows instead of between them, and a tree the platform would not signal while the parent is gone is reported as unresolved-tree rather than rounded to "gone". That reason fails allExited, so the cwd stays. A survivor now has an owner that outlives its turn. A turn's admission is core's to return, and a client cancel ends the response body while the teardown is still running; the harness is not core's. A teardown takes a bounded cleanup lease before the ladder starts, and what the ladder cannot settle moves to the quarantine with the lease and the pinned child handles: a later turn sweeps it, a survivor that closes hands the lease back, one that never does is retried with SIGKILL until the two-minute bound drops it with a warning. So an owned process no longer accumulates behind an admission count that has already been returned. Finally, a completed answer is not handed over while this server still owns a process it could not take down: the buffered terminal is delivered as harness_teardown_unresolved instead of done, the same way a teardown outside the bounded accounting is reported. The ordinary path is unchanged - the harness exits, allExited is true, the completion stands. Regressions (49 -> 53 in the adapter file): the group KILL for an exited-but-unclosed parent, the dead-parent inherited-pipe tree that reports unresolved-tree and fails allExited, a quarantined survivor that closes later and returns its lease, the cancelled turn whose cleanup lease is still held once the turn slot is back, and the turn that withholds its answer with an unreachable tree. The inherited-pipe case that used to assert allExited: true now asserts the safe outcome, which was the reviewer's point about it. Counter-proof: with the tree signal, the unresolved-tree classification, the quarantine and the withheld terminal reverted to the previous behaviour, exactly the five new cases fail (48 pass / 5 fail); with only the cleanup lease removed, the cancelled-turn and quarantine cases fail.
… keep tree uncertainty The delta review of 7fef24c asked for two more things, and both hold. The cleanup accounting did not bound the harnesses it accounted for: the lease was taken inside terminate(), after the process already existed, so a null lease changed the eventual answer and nothing else. The lease is now reserved in the spawn hook, where the bound decides whether a harness exists at all; it is held until that child's close proves the exit; and a turn above the bound is refused with harness_capacity_exhausted instead of starting a process it cannot account for. Eviction and the age bound no longer return capacity either: an entry whose process never reported an exit stays, keeps its lease, is retried with SIGKILL by every later turn, and is named once when it passes the age bound. The quarantine cannot outgrow the bound, because the spawn that would exceed it never happens. Tree uncertainty was recorded only when the direct parent was already gone at the instant of the signal, which loses the timing that matters: TERM and KILL reach no tree while the parent still lives, the parent exits inside the KILL window after the direct signal, a descendant keeps the inherited pipes - and the teardown reads pipes-held with "everything exited" for a tree it never touched. A refused tree signal is now recorded whether or not the parent was gone then, an exited child with an unreachable tree is reported as unresolved-tree, and POSIX ESRCH is read for what it is (the group is empty, i.e. no descendant left) rather than as a refusal. Regressions: the bound refuses the next harness (supervisor and turn level, no process started), a survivor past the age bound keeps its capacity and is named once, a tree signal that failed while the parent lived is not cleared when the parent exits later in the ladder, and a real launcher whose real TERM-resistant descendant holds the inherited pipes is killed with the group (pgrep finds the descendant before, not after) - no EventEmitter, no injected verdict. The cancellation case supplies a real abort signal and a parked turn now, so the ladder runs because of the cancellation rather than because the frames ended. Adapter file 53 -> 58 tests. Counter-proof: with the reservation, the lease release and the tree rule reverted, exactly the five cases tied to them fail (52 pass / 5 fail), and the timing case fails on the previous tree rule alone.
…d pipe close The cleanup lease came back on any `close`, and the quarantine sweep read `child.closed` as settled. For an unresolved tree those describe the same event the ladder has just caused itself: `reclaimPipes()` destroys the turn's own side of the pipes, Node then emits `close` for a process whose descendant still holds them, and the capacity went back for a survivor that is still running against the working directory this turn kept. The ladder now latches the unresolved-tree verdict before it reclaims the pipes, a latched child keeps its lease past `close`, and the sweep asks the platform - `kill(-pid, 0)`, where ESRCH is the group being empty - before it hands the capacity back. Windows cannot be asked, so the ownership stays there instead of being guessed away. Regression: a fake child whose `close` only arrives once the turn destroys its own streams, with a probe reporting the descendant still alive. With the release-on-close rule restored, that case reports no active lease where the fix keeps one.
… was refused The latch was keyed on the settlement label, so a child that was still `running` at the deadline was not latched even though its tree call had been refused the whole time. The ladder then reclaimed its pipes, the child died later, its `close` returned the lease, and the next sweep dropped the handle - with a descendant behind an unreachable tree that may still be alive. The label stays what the ladder saw of the direct parent (`running`, `pipes-held`, `unresolved-tree`); the lease follows the tree, so it is held whenever the tree call could not be delivered, and only the platform's answer that the group is empty returns it. Regression: a child that ignores every signal, with a refused tree call, whose exit and close arrive with the turn's own pipe reclamation while a probe reports the descendant still alive. With the label-based latch restored the lease drops to zero there. Also updates the quarantine sweep comment in sdk-turn.ts, which still described unobservable entries as dropped at the age bound.

Summary
claude-cli(feat(provider): add a Claude Code CLI subscription provider #5712), an id that named the transport it used to be and collided with the identity module of the same name. It is nowclaude-agent-sdk("Claude Agent SDK (subscription)"), adapter key and module follow, and the retired id keeps resolving throughDEPRECATED_PROVIDER_ALIASES.claude-provider-rename-migrationmoves the saved row, a custom-named row's adapter string and every cross-config reference the shared rewriter owns, and refuses with a warning where two rows would collide (two rows can describe two different sign-ins).--mcp-config: the adapter calls the SDK'squery()with the preset kept and appended to,tools: [],settingSources: [],strictMcpConfig: trueandpersistSession: false, so no built-in tool, no CLAUDE.md, skill, hook, plugin or foreign MCP source, and no transcript in the operator's~/.claude. The request's tool catalog is served from this process (type: "sdk"), which advertises the request's own JSON Schema, captures calls and never answers one, so approval, sandboxing and execution stay with the client.@anthropic-ai/claude-agent-sdkunderoptionalDependenciesplus its platform package (the Claude Code build it drives, ~230 MB unpacked; its peers@modelcontextprotocol/sdkandzodare already runtime dependencies here).MAINTAINERS.mdrequires security review for dependency installation, so this PR does not claim it:hygienereportsunsponsored_surfaceonpackage.json/bun.lockuntil a maintainer appliesmaintainer-sponsored. That review, and nothing else, is what this PR is waiting for. A compiled single-file build cannot resolve the package out of$bunfs, so it drives theclaudeonPATHand reportscli_not_foundwhen it is missing; both paths are in the provider guide.tests/claude-integration/keeps itsclaude-clifile: that one pins the CLI client path, not this provider.Verification

The preset list in
contributing.mdis answered against the harness contract rather than a vendor gateway. Destination, credential path and base URL are what 2.65.0 already shipped; what changes is who drives the turn.anthropic-apikeyremains the path without an interpretation question, and the row note says the same in the dashboard.Supply-chain review surface

Nothing is fetched at install time; the platform package contains the binary. At turn time the harness starts with

Import is a library load and nothing else. Probe on this head -

Turn time is bounded by the option set: no built-in tools, no CLAUDE.md, skills, hooks, plugins or the machine's own MCP servers, no transcript, and an empty per-turn scratchcwdremoved once the harness exits. What stays opaque is the vendor binary itself; the environment replacement, the option set and the scratch directory are the boundary this repository controls. If the binary's own runtime behaviour should be traced or run under a sandbox for the record, say so and I will.Supported-platform fallback. The SDK declares eight
os/cpu-gated platform packages as its own optional dependencies, all pinned to0.3.282, so only the target in use is installed. A compiled single-file build cannot resolve the bundled copy out of$bunfs, so there the turn drives theclaudeonPATHand answerscli_not_found(500, non-retryable, with the install hint) when it is missing - the same requirement this row had before the SDK. Live Windows evidence for thetaskkill /PID <pid> /T /Fpath is the one thing that cannot be produced from here: there is no Windows host and the fork's exact-head workflows sit ataction_required. That path keepsunresolved-treefor a tree that cannot be walked from a dead pid and a probe answering "present", so capacity is retained rather than returned on aclosethat only speaks for stdio. Unverified here rather than claimed as tested.Optional-install omission. The entry sits in
optionalDependencies, so--omit=optionalskips it. The adapter loads the SDK dynamically and maps a failed load toclaude_agent_sdk_unavailable(500, non-retryable) instead of failing the proxy at startup, covered bytests/providers/claude-agent-sdk-adapter.test.ts.Credentials and session boundary. OpenCodex stores no Claude token for this row, reads none and injects none, and never hands the configured API key to the harness (
buildChildEnvignores both). The SDK replaces the child environment with that map, and the shared base drops every inheritedANTHROPIC_*name - which is also what keeps aclaudealready pointed at this proxy from looping back into it. The only inherited name added back isUSER, which is not a credential: the harness resolves its own sign-in by account name (measured withclaude auth statusunderenv -i-USERalone reportsloggedIn: true, neitherUSERnorLOGNAMEreportsfalse). The sign-in is the operator's own (macOS Keychain, or~/.claude/.credentials.jsonelsewhere) and is the account billed.One open item that is the reviewer's call, not mine. A vendor binary under "all rights reserved" terms with no SPDX identifier is a different kind of optional dependency than the ones this repository already declares. If that is not acceptable here, the row goes back to requiring a
claudethe operator installed themselves and the dependency comes out.Checklist
