It +cannot make two different tool sets byte-identical. This proposal addresses the +tool-set mutation caused by deferred-tool reveal in the main session. + +## Goals + +- Keep main-session `functionDeclarations` bytes stable when `tool_search` + presents a hidden deferred tool. +- Preserve discovery: the model still has to receive the target tool's real + schema before it can call that tool. +- Preserve existing execution boundaries: target validation, permissions, + confirmation, hooks, telemetry, streaming, truncation, cancellation, and result + recording still go through `CoreToolScheduler`. +- Preserve subagent and teammate tool restrictions. +- Preserve plan mode, the startup path when `tool_search` is disabled, + compression, and session resume behavior. +- Limit implementation to the registry, main-session tool surface, scheduler + normalization, and lifecycle integration points. + +## Benefit + +The following is the expected architectural benefit. Automated tests can prove +that declarations remain byte-stable, but they cannot prove a provider-level +cache-hit or latency improvement. Those outcomes must be measured during a +controlled rollout and are not merge-time claims. + +After implementation, discovering a deferred tool no longer changes the main +session's API tools block. Providers can keep reusing the stable prefix that +contains `tools/functionDeclarations`, the system instruction, and early +history. Local model services that support prefix/KV reuse also avoid +re-prefilling an unchanged prefix merely because a deferred tool was discovered. + +A flow closer to the real path: + +```text +User request: + "Run npm run report every morning at 9 and write the result into + the daily report file." + +Current behavior: + Request 1 + tools/functionDeclarations: + [read_file, edit, tool_search] + history: + user: Run npm run report every morning at 9 and write the result into + the daily report file. + + The model discovers that it needs a scheduling tool: + functionCall: tool_search({ query: "cron create scheduled task" }) + + tool_search returns cron_create's schema and reveals this deferred tool. + Qwen Code then calls setTools(), adding cron_create to the API tools. + + Request 2 + tools/functionDeclarations: + [read_file, edit, tool_search, cron_create] + history: + user: Run npm run report every morning at 9 and write the result into + the daily report file. + model: tool_search(...) + tool: cron_create schema + + Result: + Request 2's tools prefix has cron_create in addition to Request 1. + The change happens at the very front of the request, so the prompt-cache + prefix built over tools + system + early history may not be reusable. + +New design: + Request 1 + tools/functionDeclarations: + [read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] + history: + user: Run npm run report every morning at 9 and write the result into + the daily report file. + + The model still searches for the real tool first: + functionCall: tool_search({ query: "cron create scheduled task" }) + + tool_search returns cron_create's real schema and tells the model in the + result to later call: + deferred_tool_call({ + name: "cron_create", + arguments: { ...params matching the cron_create schema... } + }) + + Qwen Code only records that cron_create's schema has been shown to the model. + It does not call setTools(), and it does not add cron_create to API tools. + + Request 2 + tools/functionDeclarations: + [read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] + history: + user: Run npm run report every morning at 9 and write the result into + the daily report file. + model: tool_search(...) + tool: cron_create schema plus instructions to use deferred_tool_call + + The model calls: + functionCall: deferred_tool_call({ + name: "cron_create", + arguments: { + schedule: "0 9 * * *", + command: "npm run report", + description: "Generate the daily report file" + } + }) + + After scheduler normalization, Qwen Code internally executes: + cron_create({ + schedule: "0 9 * * *", + command: "npm run report", + description: "Generate the daily report file" + }) + + Result: + Request 1 and Request 2 have exactly the same tools/functionDeclarations. + The new cron_create schema appears only in the history tool-result suffix. + It does not change the tools prefix at the very front of the request, so + prompt cache is more likely to hit. +``` + +This benefit does not rely on bypassing permissions or weakening validation: +real execution still enters the existing `CoreToolScheduler`, where the target +tool's own permissions, parameter validation, hooks, telemetry, and result +recording apply. + +## Design Invariants + +The implementation must preserve all of the following invariants: + +1. A proxy call must not grant permission to a target tool that the current + execution context cannot call directly. +2. The model must not call a target through the proxy before that target's + current schema has appeared in the active model context. +3. Permissions, hooks, UI, telemetry, validation, and execution use the real + target name and target arguments. +4. Provider responses use the provider-visible call name and original call ID. +5. Normalization and execution use the same resolved target instance; a + same-name replacement must never be substituted after authorization. +6. Tool removal, MCP reconnect, or schema changes invalidate prior proxy + eligibility. +7. Compression and resume must not preserve only proxy eligibility without also + restoring the corresponding current schema into model-visible context. +8. `includeDeferred`, `visibleTools`, `alwaysLoad`, resume-time direct + compatibility exposure, and proxy eligibility remain independent from one + another. + +## Scope by Execution Context + +| Context | Deferred tool exposure | `deferred_tool_call` | +| ---------------------------------------------------------------- | ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------- | +| Main session with `tool_search` enabled | Schema is exposed through `tool_search`; execution goes through the proxy | Included | +| Main session without `tool_search` enabled | All deferred declarations are exposed directly at startup | Omitted | +| Subagent or teammate | Keep existing effective direct declarations after exclusions and `disallowedTools` | Omitted | +| Resume of an old-format session containing direct deferred calls | Real tool names used before are exposed directly in the resumed session | Omitted for those calls; newly searched tools in the main session can still use the proxy | + +Keeping the proxy out of subagent registries is a safety requirement, not an +optimization. Subagent authorization currently filters provider-visible tool +names before scheduling. If a shared proxy name were available, the real target +would be hidden and could bypass `EXCLUDED_TOOLS_FOR_SUBAGENTS` and +`disallowedTools` checks. + +## Target Architecture + +The proxy is only a stable provider declaration. It is not an executor. The +normalization boundary converts the provider call into a real scheduled call +before target permission checks. + +```mermaid +flowchart LR + subgraph ProviderBoundary["Provider boundary"] + A["functionCall name: deferred_tool_call"] + B["args: target name and target arguments"] + end + + subgraph Normalization["Main-session call normalization"] + C["Validate proxy envelope"] + D["Resolve and retain current target instance"] + E["Verify the retained instance and schema were presented"] + F["Verify target is proxy-eligible"] + end + + subgraph Scheduler["Existing CoreToolScheduler pipeline"] + G["Target permission policy"] + H["Target build and schema validation"] + I["Confirmation and hooks"] + J["Target execution and streaming"] + K["Truncation, telemetry, recording"] + end + + subgraph ResponseBoundary["Provider response boundary"] + L["functionResponse name: deferred_tool_call"] + M["Original provider call ID"] + end + + A --> C + B --> C + C --> D --> E --> F --> G --> H --> I --> J --> K --> L --> M +``` + +The normalized `ToolCallRequestInfo` carries both identities. Normal tool calls +do not have `providerName`, so existing behavior is unchanged. A proxy call +looks like: + +```text +providerName = deferred_tool_call +name = cron_create +args = {...} +``` + +All model-facing response-name builders use `providerName ?? name`. All +internal consumers use `name` and `args`. + +Permission-denial text is intentionally different from response pairing. It +identifies the policy-checked target and, for proxy calls, the provider route +(for example, `"cron_create" via "deferred_tool_call"`) so users can understand +what was denied. Custom policy or hook denial reasons are preserved and receive +the same proxy identity context. The surrounding `functionResponse.name` still +uses `providerName`, and ordinary tool denial text keeps its existing behavior. + +A successful proxy normalization also carries the resolved target instance. +Before returning it, the helper verifies that `ToolRegistry` still maps the +canonical name to that same instance. `CoreToolScheduler` and ACP +`Session.runTool()` then build and execute this retained instance instead of +resolving the name again. This binds presentation authorization, validation, +and execution to one tool object and closes the same-name replacement TOCTOU +window. Ordinary calls carry no resolved instance and keep their existing +lookup path. + +Normalization is shared core routing semantics, not private +`CoreToolScheduler` behavior. Both the main scheduler and ACP/daemon +`Session.runTool()` must call the same shared helper before tool lookup, +permission checks, hooks, telemetry, and execution. +This keeps the ACP execution path from executing the `deferred_tool_call` +wrapper fallback or bypassing the presentation gate. All provider/model-facing +function responses still use `providerName ?? name`, so hidden target names are +not written back to the provider. + +## Stable Provider Tool + +The main session adds an always-visible declaration: + +```json +{ + "name": "deferred_tool_call", + "description": "Calls a deferred tool after its current schema has been fetched with tool_search.", + "parametersJsonSchema": { + "type": "object", + "properties": { + "name": { + "type": "string", + "description": "Exact deferred tool name returned by tool_search." + }, + "arguments": { + "type": "object", + "description": "Arguments matching the target schema returned by tool_search." + } + }, + "required": ["name", "arguments"], + "additionalProperties": false + } +} +``` + +`deferred_tool_call` is a reserved core name. Tool registration must reject any +MCP, command-discovered, extension, or plugin tool that tries to use this name. + +If the proxy tool's `execute()` method is ever called, it must fail closed. It +must never call another tool itself. Every supported execution entrypoint must +intercept it during scheduler normalization. + +When using `createToolRegistry({ forSubAgent: true })`, this proxy is not +registered. That prevents the agent runtime from accidentally authorizing by +the provider-visible proxy name. + +## Registry State Model + +The existing meaning of `revealedDeferred` is overloaded. Replace it with two +separate concepts. + +### Proxy schema presentation + +Maintain a map such as: + +```ts +proxySchemaPresentations: Map; +``` + +The key is the canonical target name. The value is the deterministic fingerprint +of the exact schema already shown to the model. Before this committed map is +updated, `tool_search` carries the displayed schema identity through the result +lifecycle as pending metadata: + +```ts +interface DeferredToolPresentation { + name: string; + schemaFingerprint: string; +} +``` + +The fingerprint must be computed from the same captured `FunctionDeclaration` +that is rendered into the model-facing schema block. Committing a presentation +is a compare-and-set operation: resolve the current tool by `name`, verify that +it is still proxy-eligible, and commit only when its current schema fingerprint +equals `schemaFingerprint`. Never recompute authorization from the name alone. +If MCP refresh replaces schema A with schema B after rendering but before +commit, the pending presentation for A is rejected and the model must run +`tool_search` again for B. + +A target is proxy-eligible only when all of these conditions hold: + +- It currently exists. +- It is deferred. +- It is not `alwaysLoad` and not in `visibleTools`. +- Its current schema fingerprint matches the recorded fingerprint. +- The current execution context is the main session. + +Deletion, MCP disconnect/reconnect, tool replacement, or schema fingerprint +changes invalidate the corresponding committed presentation entry. The +commit-time comparison additionally closes the render-to-commit replacement +window, including delayed ACP delivery. + +### Direct declaration visibility + +Direct declaration visibility remains an independent decision: + +```text +include in declarations when: + includeDeferred + OR not shouldDefer + OR alwaysLoad + OR visibleTools contains the name + OR revealDeferredTool(name) marked it revealed for this session +``` + +`proxySchemaPresentations` must never affect +`ToolRegistry.getFunctionDeclarations()`. Therefore, `tool_search` does not +change the API tools block. + +For old direct-call history, resume uses the existing +`ToolRegistry.revealDeferredTool(name)` compatibility path before the first +request of the resumed chat. This keeps real deferred tool names that already +appear in history callable by direct declaration for that resumed session. +Normal `tool_search` calls do not use this direct compatibility path; they +return model-visible schemas for `deferred_tool_call` instead. + +## Tool Search Flow + +In the main session, `tool_search` continues to resolve lazy factories and +render real target schemas, but no longer calls `GeminiClient.setTools()`. + +```mermaid +sequenceDiagram + participant M as Model + participant TS as tool_search + participant R as ToolRegistry + participant S as CoreToolScheduler + participant H as Active chat history + participant T as Real deferred tool + participant P as Provider + + M->>TS: select:cron_create + TS->>R: ensureTool(cron_create) + R-->>TS: current tool and schema + TS-->>S: escaped schema plus pending fingerprint metadata + S->>H: append successful tool result + H->>R: commit presented schema fingerprint + H-->>M: next request contains the schema result + Note over R,P: No setTools call.

Pending metadata that has not entered active + history does not hide the target; schema replacement invalidates the old + fingerprint and makes the target searchable again. +- Use the existing wrapper escaping when rendering schemas, so untrusted + descriptions cannot break out of the model-facing envelope. +- Return `{ name, schemaFingerprint }` as internal pending metadata on the + successful tool result. Compute the fingerprint from the same captured schema + object used to render the response. Do not modify committed presentation + state inside `tool_search.execute()`. +- Commit presentation state only after the successful result containing the + schema has been appended to active chat history. Cancellation, result delivery + failure, or history rollback must not unlock the live proxy. Pending metadata + may be persisted with the tool-result recording for resume, but it is not + authorization. At commit or resume restoration, reject the metadata if the + current schema fingerprint no longer matches the displayed fingerprint. +- ACP/daemon stages `deferredToolPresentations` on the exact user message that + carries the successful `tool_search` function response. It commits them only + after that message enters active model history. Tool execution failure, + cancellation, PostToolUse stop, delivery failure, or history rollback must + not unlock the proxy. +- Remove `setTools()` and its reveal/API-sync rollback. If result construction + fails, do not retain pending metadata; if delivery fails, do not commit it to + live presentation state. +- Explicitly tell the model to use `deferred_tool_call` on a later turn. + +The same response cannot both present and invoke a new target. The scheduler +checks presentation state before executing the batch, so if the first +`tool_search` for a target is parallel with a proxy call for that target, the +proxy call is rejected. + +## Scheduler Normalization and Authorization + +Before the existing target permission flow: + +1. Detect provider calls named `deferred_tool_call`. +2. Reject unless the runtime is a top-level main session. +3. Validate the envelope: + - `name` is a non-empty string; + - `arguments` is a non-null, non-array plain object. +4. Canonicalize the target name and reject self-target recursion, where the + proxy envelope names + `deferred_tool_call` itself as the target tool. This check does not reject + multiple proxy calls to different real deferred tools in the same session. +5. Resolve the current target from `ToolRegistry`, retain that exact tool + instance, and reject load failures or missing targets. +6. Verify that the registry still maps the canonical name to the retained + instance. +7. Reject normally visible or `alwaysLoad` targets and tell the model to call + them by their real names. +8. Compare the retained instance's current schema fingerprint with the + presentation record. +9. Construct a normalized request using the real target `name` and `args`, while + preserving `providerName`, call ID, provider call ID, prompt ID, response + ID, and truncation state; return the retained target instance with it. +10. Run the unchanged target permission, build, confirmation, hook, scheduling, + execution, timeout, streaming, truncation, and recording pipeline using the + retained instance, without resolving the target name again. + +Therefore, the first permission decision after normalization targets the real +tool, not the proxy. Unknown and unrevealed target errors are returned under the +provider-facing proxy name, preserving a valid provider call/result pair. + +Self-target recursion should be handled as a normal tool-call error, not a +crash and not an attempt to keep executing. The response still uses the +provider-facing proxy name and original call ID, and tells the model to fetch +the intended real deferred tool schema with `tool_search`, then call +`deferred_tool_call` with that real target name. Allowing the proxy to target +itself has no valid execution semantics: the proxy is only a provider-facing +transport wrapper, not a business tool. Normalizing it to itself would make the +execution identity ambiguous. + +## Response and Observability Rules + +Use the real target identity in these places: + +- permission rules and policy classifiers; +- parameter validation and retry counters; +- confirmation text; +- PreToolUse, PostToolUse, and PostToolUseFailure hooks; +- UI tool name, arguments, output, and duration; +- per-tool truncation limits; +- execution spans and tool statistics. + +Use the provider identity in these places: + +- `functionResponse.name`; +- provider tool-call pairing; +- reconstructed API history. + +Record both identities for proxied calls: + +```text +tool.name = cron_create +tool.provider_name = deferred_tool_call +``` + +All success, validation-error, permission-denial, hook-denial, cancellation, +timeout, and unhandled-exception response paths must use the same centralized +provider-name helper. Existing `FunctionResponse` parts returned by a tool must +also be normalized at this boundary instead of passing through with the target +name. Permission-denial messages use the real target plus proxy route for user +clarity, without changing this provider-facing response-name rule. + +## Lifecycle and Compatibility + +### Plan mode + +`exit_plan_mode` is a lifecycle-control tool, not an ordinary on-demand feature. +It should appear directly in the stable main-session declaration set from +startup. `enter_plan_mode` no longer reveals it and no longer calls +`setTools()`. + +Calling it outside plan mode still uses the existing runtime validation. The +cost is one additional tool in every stable schema; that cost is acceptable so +plan-mode exit does not depend on a special proxy/reveal exception. + +### Unavailable discovery/proxy pair + +In the main session, `tool_search` and `deferred_tool_call` form one capability. +If either tool is unavailable because of configuration or permission policy: + +- omit both tools, rolling back a pending `tool_search` factory when proxy + registration fails; +- build initial main-session declarations with + `getFunctionDeclarations({ includeDeferred: true })`; +- do not advertise on-demand discovery. + +This decision happens before the first request, so the larger declaration set is +still stable for that chat. + +### Subagents and teammates + +Subagents and teammates keep the current behavior: + +- build direct declarations from their effective `toolsList`; +- apply context exclusions and `disallowedTools` to real names; +- never register or advertise `deferred_tool_call`; +- defensively reject hallucinated proxy names before target resolution. + +### Compression + +Compression invalidates proxy presentation state conservatively. Automatic, +micro, and fast compression clear the fingerprint ledger, so the model must use +`tool_search` again before another proxied call. Manual full compression routes +the compressed history through the resume logic below: if complete successful +proxy call/response pairs survive, their current schemas are appended as a +user-role runtime reminder and only matching fingerprints are restored. + +This deliberately accepts the post-compression rediscovery tradeoff for the +first implementation. Snapshotting valid presentation names before compression +and re-injecting current schemas afterward is a possible follow-up optimization, +but it needs separate evaluation of token cost and authorization semantics. It +must remain a history suffix and must not modify the stable tools or system +prefix. + +### Session resume + +Resume handles two history formats: + +- New proxy history: scan `deferred_tool_call` arguments for target names, + resolve current schemas, append them as an escaped, pure structural + `` user entry, and rebuild presentation fingerprints. The + structural envelope prevents Retry cleanup from treating restored schema + context as an orphaned user prompt. Restore this proxy state only when the + warmed registry still contains both `tool_search` and `deferred_tool_call`; + either tool alone is not a callable discovery/proxy capability. +- Recorded `tool_search` history: restore schema-bound pending metadata only + when its matching successful function response remains in the final resumed + API history after compression, recovery, and retry cleanup. The registry + revalidates the current schema fingerprint before restoring authorization. +- Old direct history: collect real deferred function-call names and pass them + through `ToolRegistry.revealDeferredTool(name)` before building initial + declarations. In that resumed chat, their declarations stay direct and + stable. + +If either proxy control tool is unavailable, resume skips proxy presentation +restoration and uses the startup direct-declaration fallback. Old direct-call +compatibility remains independent of proxy availability. + +History itself never grants execution permission. Current registry existence, +current schema presentation, execution-context policy, and target permissions +must still apply. + +Retry cleanup preserves presentation state when it removes only a failed user +prompt because the schema-bearing history remains active. If cleanup removes a +`tool_search` function response, it clears all proxy presentations rather than +attempting to reconstruct partial authorization from history text. Other broad +history mutations continue to clear presentation state conservatively. + +### Clear and MCP lifecycle + +`/clear` clears proxy presentation and session-direct visibility state. MCP +removal, disconnect, reconnect, or replacement clears presentation state for +affected names. Reconnected tools must be searched again so the model can see +their current schemas. + +## Before and After + +Current main-session sequence: + +```text +Request 1 tools: +[read_file, edit, tool_search] + +tool_search reveals cron_create + -> revealDeferredTool("cron_create") + -> setTools() + +Request 2 tools: +[read_file, edit, tool_search, cron_create] +``` + +Revised main-session sequence: + +```text +Request 1 tools: +[read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] + +tool_search presents cron_create + -> ensureTool("cron_create") + -> return current escaped schema + -> return pending { name, schemaFingerprint } metadata + -> after the result enters active history, compare pending fingerprint with + the current registry schema and commit only if they still match + -> no setTools() + +Request 2 tools: +[read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] + +Provider call: +deferred_tool_call({ name: "cron_create", arguments: {...} }) + +Internal scheduled call: +cron_create({...}) + +Provider response: +functionResponse({ name: "deferred_tool_call", id: originalCallId, ... }) +``` + +## Costs and Validation Gates + +- The stable proxy and directly visible `exit_plan_mode` add fixed tokens to + every normal main-session request. +- Each proxied call adds a small `name` / `arguments` envelope. +- The provider can only structurally validate the generic proxy envelope; target + schema validation happens inside Qwen Code. Compared with sending the real + target schema as an API declaration, this may increase invalid-parameter + retries. +- Compression and resume may re-append schemas as tail context. +- The scheduler request identity model becomes slightly richer. + +### Merge gates + +Merging the implementation requires correctness evidence that can be verified +deterministically in CI: + +- byte-level declaration stability tests pass before and after repeated + `tool_search` presentations; +- normalization, authorization, provider response pairing, lifecycle, resume, + compression, Core scheduler, and ACP regression tests pass; +- build, typecheck, formatting, and lint checks pass. + +These gates establish implementation correctness and declaration stability. +They do not establish that any provider will produce more cache hits, lower +latency, or better end-to-end quality. An A/B performance report is therefore +not a merge gate. + +### Rollout and activation gates + +The discovery/proxy pair is registered by default when both tools pass existing +configuration and permission gates. Environments that require staged +provider/model validation can disable or deny `deferred_tool_call` through the +existing tool configuration. That path unregisters `tool_search` and retains +the direct deferred-declaration fallback. + +Before expanding activation for a provider/model combination, the rollout owner +must define acceptable regression thresholds, run a representative baseline +and proxy-enabled comparison, and review raw measurements for: + +- serialized declaration bytes before and after repeated searches; +- cached input tokens or cache-read ratio; +- time to first token; +- fixed prompt-token overhead; +- deferred-call first-attempt success rate; +- target validation retry rate; +- behavior after compression and resume. + +Activation should expand only when declaration stability is preserved and the +report shows an acceptable cache/latency benefit without a material regression +in tool-call success, validation retries, compression, or resume behavior. If +the comparison is neutral, inconclusive, or regressive, keep the proxy disabled +for that provider/model and use the direct fallback.

Committing a presentation -is a compare-and-set operation: resolve the current tool by `name`, verify that -it is still proxy-eligible, and commit only when its current schema fingerprint -equals `schemaFingerprint`. Never recompute authorization from the name alone. -If MCP refresh replaces schema A with schema B after rendering but before -commit, the pending presentation for A is rejected and the model must run -`tool_search` again for B. - -A target is proxy-eligible only when all of these conditions hold: - -- It currently exists. -- It is deferred. -- It is not `alwaysLoad` and not in `visibleTools`. -- Its current schema fingerprint matches the recorded fingerprint. -- The current execution context is the main session. - -Deletion, MCP disconnect/reconnect, tool replacement, or schema fingerprint -changes invalidate the corresponding committed presentation entry. The -commit-time comparison additionally closes the render-to-commit replacement -window, including delayed ACP delivery. - -### Direct declaration visibility - -Direct declaration visibility remains an independent decision: - -```text -include in declarations when: - includeDeferred - OR not shouldDefer - OR alwaysLoad - OR visibleTools contains the name - OR revealDeferredTool(name) marked it revealed for this session -``` - -`proxySchemaPresentations` must never affect -`ToolRegistry.getFunctionDeclarations()`.

Detect provider calls named `deferred_tool_call`. -2. Reject unless the runtime is a top-level main session. -3. Validate the envelope: - - `name` is a non-empty string; - - `arguments` is a non-null, non-array plain object. -4. Canonicalize the target name and reject self-target recursion, where the - proxy envelope names - `deferred_tool_call` itself as the target tool. This check does not reject - multiple proxy calls to different real deferred tools in the same session. -5. Resolve the current target from `ToolRegistry`, retain that exact tool - instance, and reject load failures or missing targets. -6. Verify that the registry still maps the canonical name to the retained - instance. -7. Reject normally visible or `alwaysLoad` targets and tell the model to call - them by their real names. -8. Compare the retained instance's current schema fingerprint with the - presentation record. -9.

The response still uses the -provider-facing proxy name and original call ID, and tells the model to fetch -the intended real deferred tool schema with `tool_search`, then call -`deferred_tool_call` with that real target name. Allowing the proxy to target -itself has no valid execution semantics: the proxy is only a provider-facing -transport wrapper, not a business tool. Normalizing it to itself would make the -execution identity ambiguous. - -## Response and Observability Rules - -Use the real target identity in these places: - -- permission rules and policy classifiers; -- parameter validation and retry counters; -- confirmation text; -- PreToolUse, PostToolUse, and PostToolUseFailure hooks; -- UI tool name, arguments, output, and duration; -- per-tool truncation limits; -- execution spans and tool statistics. - -Use the provider identity in these places: - -- `functionResponse.name`; -- provider tool-call pairing; -- reconstructed API history. - -Record both identities for proxied calls: - -```text -tool.name = cron_create -tool.provider_name = deferred_tool_call -``` - -All success, validation-error, permission-denial, hook-denial, cancellation, -timeout, and unhandled-exception response paths must use the same centralized -provider-name helper. Existing `FunctionResponse` parts returned by a tool must -also be normalized at this boundary instead of passing through with the target -name. Permission-denial messages use the real target plus proxy route for user -clarity, without changing this provider-facing response-name rule. - -## Lifecycle and Compatibility - -### Plan mode - -`exit_plan_mode` is a lifecycle-control tool, not an ordinary on-demand feature. -It should appear directly in the stable main-session declaration set from -startup. `enter_plan_mode` no longer reveals it and no longer calls -`setTools()`. - -Calling it outside plan mode still uses the existing runtime validation. The -cost is one additional tool in every stable schema; that cost is acceptable so -plan-mode exit does not depend on a special proxy/reveal exception. - -### Unavailable discovery/proxy pair - -In the main session, `tool_search` and `deferred_tool_call` form one capability. -If either tool is unavailable because of configuration or permission policy: - -- omit both tools, rolling back a pending `tool_search` factory when proxy - registration fails; -- build initial main-session declarations with - `getFunctionDeclarations({ includeDeferred: true })`; -- do not advertise on-demand discovery. - -This decision happens before the first request, so the larger declaration set is -still stable for that chat. - -### Subagents and teammates - -Subagents and teammates keep the current behavior: - -- build direct declarations from their effective `toolsList`; -- apply context exclusions and `disallowedTools` to real names; -- never register or advertise `deferred_tool_call`; -- defensively reject hallucinated proxy names before target resolution. - -### Compression - -Every compaction path first clears the fingerprint ledger, because the -schema-bearing history entries may no longer be active. Micro and fast -compression stop there, so the model must use `tool_search` again before -another proxied call. - -Automatic (event-driven) and manual full compression additionally snapshot the -currently presented schemas before compacting. After the compressed chat is -rebuilt, their current schemas are re-injected as a `` block -embedded in the startup-context entry (the first history entry, alongside the -rebuilt prelude), and each snapshot is re-authorized with -`markProxySchemaPresented`, which compares the stored fingerprint against the -current registry schema — schemas that changed while compacting are not -restored. The restore embeds into the startup context rather than appending a -history suffix so Retry cleanup cannot strip it as an orphaned user turn and -so the compacted turn sequence stays intact; it still never modifies the -stable API tool declarations or the system instruction prefix. - -### Session resume - -Resume handles two history formats: - -- New proxy history: scan `deferred_tool_call` arguments for target names, - resolve current schemas, append them as an escaped, pure structural - `` user entry, and rebuild presentation fingerprints. The - structural envelope prevents Retry cleanup from treating restored schema - context as an orphaned user prompt. Restore this proxy state only when the - warmed registry still contains both `tool_search` and `deferred_tool_call`; - either tool alone is not a callable discovery/proxy capability. -- Recorded `tool_search` history: restore schema-bound pending metadata only - when its matching successful function response remains in the final resumed - API history after compression, recovery, and retry cleanup. The registry - revalidates the current schema fingerprint before restoring authorization. -- Old direct history: collect real deferred function-call names and pass them - through `ToolRegistry.revealDeferredTool(name)` before building initial - declarations. In that resumed chat, their declarations stay direct and - stable. - -If either proxy control tool is unavailable, resume skips proxy presentation -restoration and uses the startup direct-declaration fallback. Old direct-call -compatibility remains independent of proxy availability. - -History itself never grants execution permission. Current registry existence, -current schema presentation, execution-context policy, and target permissions -must still apply. - -Retry cleanup preserves presentation state when it removes only a failed user -prompt because the schema-bearing history remains active. If cleanup removes a -`tool_search` function response, it clears all proxy presentations rather than -attempting to reconstruct partial authorization from history text. Other broad -history mutations continue to clear presentation state conservatively. - -### Clear and MCP lifecycle - -`/clear` clears proxy presentation and session-direct visibility state. MCP -removal, disconnect, reconnect, or replacement clears presentation state for -affected names. Reconnected tools must be searched again so the model can see -their current schemas. - -## Before and After - -Current main-session sequence: - -```text -Request 1 tools: -[read_file, edit, tool_search] - -tool_search reveals cron_create - -> revealDeferredTool("cron_create") - -> setTools() - -Request 2 tools: -[read_file, edit, tool_search, cron_create] -``` - -Revised main-session sequence: - -```text -Request 1 tools: -[read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] - -tool_search presents cron_create - -> ensureTool("cron_create") - -> return current escaped schema - -> return pending { name, schemaFingerprint } metadata - -> after the result enters active history, compare pending fingerprint with - the current registry schema and commit only if they still match - -> no setTools() on the normal path (only the oversized escape hatch - declares a too-large schema directly and calls setTools()) - -Request 2 tools: -[read_file, edit, tool_search, deferred_tool_call, exit_plan_mode] - -Provider call: -deferred_tool_call({ name: "cron_create", arguments: {...} }) - -Internal scheduled call: -cron_create({...}) - -Provider response: -functionResponse({ name: "deferred_tool_call", id: originalCallId, ... }) -``` - -## Costs and Validation Gates - -- The stable proxy and directly visible `exit_plan_mode` add fixed tokens to - every normal main-session request. -- Each proxied call adds a small `name` / `arguments` envelope. -- The provider can only structurally validate the generic proxy envelope; target - schema validation happens inside Qwen Code. Compared with sending the real - target schema as an API declaration, this may increase invalid-parameter - retries. -- Compression restore embeds current schemas into the rebuilt startup-context - entry; resume re-appends them as a user-role reminder entry. -- The scheduler request identity model becomes slightly richer. - -### Merge gates - -Merging the implementation requires correctness evidence that can be verified -deterministically in CI: - -- byte-level declaration stability tests pass before and after repeated - `tool_search` presentations; -- normalization, authorization, provider response pairing, lifecycle, resume, - compression, Core scheduler, and ACP regression tests pass; -- build, typecheck, formatting, and lint checks pass. - -These gates establish implementation correctness and declaration stability. -They do not establish that any provider will produce more cache hits, lower -latency, or better end-to-end quality. An A/B performance report is therefore -not a merge gate. - -### Rollout and activation gates - -The discovery/proxy pair is registered by default when both tools pass existing -configuration and permission gates. Environments that require staged -provider/model validation can disable or deny `deferred_tool_call` through the -existing tool configuration. That path unregisters `tool_search` and retains -the direct deferred-declaration fallback. - -Before expanding activation for a provider/model combination, the rollout owner -must define acceptable regression thresholds, run a representative baseline -and proxy-enabled comparison, and review raw measurements for: - -- serialized declaration bytes before and after repeated searches; -- cached input tokens or cache-read ratio; -- time to first token; -- fixed prompt-token overhead; -- deferred-call first-attempt success rate; -- target validation retry rate; -- behavior after compression and resume. - -Activation should expand only when declaration stability is preserved and the -report shows an acceptable cache/latency benefit without a material regression -in tool-call success, validation retries, compression, or resume behavior. If -the comparison is neutral, inconclusive, or regressive, keep the proxy disabled -for that provider/model and use the direct fallback. Because cache and quality -metrics depend on the provider, model, and workload, the report must identify -those dimensions and include raw measurements rather than assuming that stable -schema necessarily yields a net benefit. - -## Security Analysis - -- The proxy is not authorization. It only transports a provider call to the real - target identity. -- Main-session-only registration prevents proxy-name authorization from - bypassing agent real-name restrictions. -- The target permission manager runs after normalization and before execution. -- Real target schema validation remains mandatory; the generic proxy schema is - insufficient. -- Schema fingerprints prevent a schema shown before MCP reconnect from - authorizing a current tool with the same name but a different definition. -- Retaining the normalized tool instance prevents a same-name replacement from - being executed after a different instance passed presentation checks. -- Reserved-name enforcement prevents registration sources from shadowing the - dispatcher surface. -- Untrusted MCP schema text uses the existing escaping and is explicitly - described as metadata, not instructions. -- Proxy recursion and proxying directly visible tools are rejected. -- Error responses do not leak hidden target schemas; when presentation is - missing, they only tell the model to use `tool_search`. - -## Source Change Map - -| Source area | Required change | -| ---------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -| `packages/core/src/tools/tool-names.ts` | Add the reserved proxy name and display name. | -| `packages/core/src/config/config.ts` | Register `tool_search` and the proxy atomically for the main registry, rolling search back if proxy registration fails; keep the proxy out of `forSubAgent` registries. | -| `packages/core/src/tools/tool-registry.ts` | Separate committed proxy presentations from direct declaration visibility, compare pending and current schema fingerprints at commit, preserve `includeDeferred` behavior, reserve the proxy name, and invalidate fingerprints on tool lifecycle changes. | -| `packages/core/src/tools/tool-search.ts` | Render a captured schema and return its name plus fingerprint as pending presentation metadata; keep `setTools()` only for the oversized escape hatch that declares a single too-large schema directly (with reveal rollback on failure). | -| `packages/core/src/core/deferred-tool-call-normalization.ts` | Provide the shared normalization helper for proxy envelope validation, target resolution, instance binding, presentation gating, and provider-facing response naming. | -| `packages/core/src/core/turn.ts` | Explicitly represent provider identity and execution identity. | -| `packages/core/src/core/coreToolScheduler.ts` | Reuse the shared helper to normalize proxy calls before target authorization, execute the retained target instance, show target plus route in permission denials, centralize provider response naming, and forward pending presentation metadata. | -| `packages/core/src/core/client.ts` | Require the complete discovery/proxy capability before resume restoration; restore only active recorded presentations; protect restored schema context from Retry stripping; invalidate presentation state on compaction and broad history mutation; snapshot and restore current schemas across automatic and manual compression. | -| `packages/cli/src/acp-integration/session/Session.ts` | Reuse the shared helper and retained target instance in ACP's independent `runTool()` path; show target plus route in permission denials; commit presentations after their response message enters active history; keep response names provider-facing. | -| `packages/cli/src/ui/hooks/useGeminiStream.ts` | Report whether the prepared tool-result context was accepted so the scheduler commits presentations only after a model request crosses the active-history boundary. | -| `packages/cli/src/nonInteractiveCli.ts` | Defer presentation commits until the complete headless provider batch has executed and final output budgeting has preserved the schema-bearing response. | -| `packages/core/src/tools/enterPlanMode.ts` and `exitPlanMode.ts` | Remove dynamic exit-tool reveal and keep the exit tool on the stable direct main-session surface. | -| `packages/core/src/agents/runtime/agent-core.ts` | Preserve real-name agent filtering and defensively reject hallucinated proxy names. | -| Provider converter tests | Verify Gemini, OpenAI, and Anthropic call/result pairing; if scheduler response normalization is complete, converter production code does not need proxy-specific routing. | - -## Implementation Plan - -1.

Delivered (canonical, fingerprint) pairs ride the ToolResult as pending presentations and are attached only on the path that actually ships the schemas; every oversized-budget fallback that withholds them (aggregate overflow retry, direct declaration, setTools-failure refusal) leaves the ledger untouched. - CoreToolScheduler settles the pending presentations against the delivery-accepted boolean returned by onAllToolCallsComplete: commit only once the carrying result is accepted into the active model context, discard on rejection (blocking UserPromptSubmit hook, cancellation, admission failure). Consumers without a delivery signal keep the pre-signal behaviour. - History mutations that can evict the carrying tool_search result (compression, microcompaction, rewind/truncation, setHistory) clear the presentation ledger in GeminiChat; revealed (directly declared) tools are unaffected since their schemas stay in the declaration list. - The shared tool-response finalizer exempts delivered tool_search schema blocks from budget fitting (finalizeToolResponses and the send-boundary guard) so a block can never be truncated/stubbed after delivery while the ledger keeps its mark. - normalizeDeferredToolCallRequest accepts a batch-start presentation snapshot so surfaces executing batch calls sequentially can deny same-batch tool_search + tool_call self-authorization.

The flipped test now asserts same-batch rejection and next-turn routing. - ACP/daemon: mirror the scheduler's wrapper deny gate. When the incoming call is the tool_call wrapper, check permissionManager.isToolEnabled(tool_call) before the target gates so mid-session deny rules naming the wrapper apply on this surface too. - ACP/daemon: delivered schema presentations commit at batch finalization (every runToolCalls return path sends or preserves the parts) instead of at tool execution, and the shared finalizer exemption keeps delivered schema blocks intact through finalizeRunToolResult. - Headless: processToolCallBatch runs normalizeDeferredToolCallRequest over every wrapper request before partitioning/launching, converting gate failures into error responses. The partition gave tool_search its own sequential batch that ran fully first, letting same-batch pairs self-authorize in the per-request schedulers. - TUI: the deferred-batch flush commits carried presentations when its own delivery is accepted, matching the scheduler settlement of the delivery-accepted signal. --- .../acp-integration/session/Session.test.ts | 145 +++++++++++++++++- .../src/acp-integration/session/Session.ts | 87 +++++++++++ packages/cli/src/nonInteractiveCli.test.ts | 120 ++++++++++++++- packages/cli/src/nonInteractiveCli.ts | 64 ++++++++ packages/cli/src/ui/hooks/useGeminiStream.ts | 38 ++++- 5 files changed, 440 insertions(+), 14 deletions(-) diff --git a/packages/cli/src/acp-integration/session/Session.test.ts b/packages/cli/src/acp-integration/session/Session.test.ts index c4fa0a02cd9..061e01d5aae 100644 --- a/packages/cli/src/acp-integration/session/Session.test.ts +++ b/packages/cli/src/acp-integration/session/Session.test.ts @@ -489,7 +489,15 @@ describe('Session', () => { schemaFingerprint: ReturnType; markProxySchemaPresented: ReturnType; hasPresentedProxySchema: ReturnType; + getProxySchemaPresentationSnapshot: ReturnType; + commitProxySchemaPresentations: ReturnType; + clearProxySchemaPresentations: ReturnType; }; + // Backing store for the mocked presentation ledger.

The send-failure ledger rollback added in a211e7046b/8bc6818fc3 gates only on the push counter, but #sendMessageStreamWithAutoCompression can compress mid-send: tryCompressChat applies the compressed history via setHistory (which this PR wires to clear the presentation ledger) and then startChat replaces the chat object, so the captured chat's counter is frozen and the gate is always true after a compression. restoreProxySchemaPresentationSnapshot then resurrects marks whose backing tool_search results were just summarized out of active history, and a later model-emitted tool_call passes the #6721 gate on a schema the model can no longer see. The stop-continuation twin shares the hole: its beforeSend capture fixes the counter but its snapshot still predates the same send's compression. Make the restore a no-op across an intervening ledger clear: ToolRegistry now tracks a monotonic generation incremented in clearProxySchemaPresentations() (clearRevealedDeferredTools routes through it too), the generation is captured with the pre-batch snapshot in runToolCalls and threaded through RunToolResult, and restoreProxySchemaPresentationSnapshot(snapshot, generation) skips the restore when the generation advanced. Both wired rollback sites pass the captured generation. Every chat-replacement path reachable inside a send clears the ledger first, so an unchanged generation implies the captured chat is still the live chat and the push-count gate stays accurate. Tests: tool-registry restore/generation coverage; Session regression test driving a mid-send compression clear followed by a pre-push send throw (the ledger stays empty) plus a control proving the plain rollback still restores when no clear intervened. --- .../acp-integration/session/Session.test.ts | 151 ++++++++++++++++++ .../src/acp-integration/session/Session.ts | 50 +++++- packages/core/src/tools/tool-registry.test.ts | 60 +++++++ packages/core/src/tools/tool-registry.ts | 30 +++- 4 files changed, 287 insertions(+), 4 deletions(-) diff --git a/packages/cli/src/acp-integration/session/Session.test.ts b/packages/cli/src/acp-integration/session/Session.test.ts index 95e1a3fba10..d1ea9662dd0 100644 --- a/packages/cli/src/acp-integration/session/Session.test.ts +++ b/packages/cli/src/acp-integration/session/Session.test.ts @@ -490,14 +490,20 @@ describe('Session', () => { markProxySchemaPresented: ReturnType; hasPresentedProxySchema: ReturnType; getProxySchemaPresentationSnapshot: ReturnType; + getProxySchemaPresentationGeneration: ReturnType; commitProxySchemaPresentations: ReturnType; clearProxySchemaPresentations: ReturnType; + restoreProxySchemaPresentationSnapshot: ReturnType; }; // Backing store for the mocked presentation ledger.

The batch-level presentation commit is shared by all four daemon runToolCalls send loops, but the send-failure rollback was wired into only two (#executePromptInner in 8bc6818fc3 and #runStopContinuation in a211e7046b). The cron/loop-tick loop (#executeCronPromptInner) and the background-notification loop (#executeBackgroundNotificationPromptInner) swallowed send errors in their outer catch without rolling the ledger back: a batch whose carrying send threw before the history push left the committed mark in the session-scoped registry, and a later model-emitted tool_call passed the #6721 gate on a schema that never entered model context. Mirror the main loop's wiring in both loops: capture chat + getUserContentPushCount() before each carrying send, clear the snapshot once the send is accepted, track toolRun.presentationSnapshot after runToolCalls, and restore the ledger to the pre-batch snapshot in the outer catch when the push counter shows the message never landed (placed before the abort early-return, matching the main loop's ordering). The restore is fail-safe (try/catch) and generation-gated (previous commit), so it can never resurrect marks an intervening clear dropped. Tests: two Session regression tests driving the real cron and background-notification loops — each proves the mark was committed at carrying-send time and is rolled back after a pre-push send throw. --- .../acp-integration/session/Session.test.ts | 138 ++++++++++++++++++ .../src/acp-integration/session/Session.ts | 107 ++++++++++++++ 2 files changed, 245 insertions(+) diff --git a/packages/cli/src/acp-integration/session/Session.test.ts b/packages/cli/src/acp-integration/session/Session.test.ts index d1ea9662dd0..8565a8b9d00 100644 --- a/packages/cli/src/acp-integration/session/Session.test.ts +++ b/packages/cli/src/acp-integration/session/Session.test.ts @@ -29588,6 +29588,144 @@ describe('Session', () => { ]);

The direct (non-flush) scheduler path settles a batch-level acceptance boolean, and CoreToolScheduler then commits pendingProxySchemaPresentations for every call in the batch — including calls whose real results handleCompletedTools dedup-dropped (the Race A synthetic placeholder).

Every delivery surface re-seeds its replay map from history — TUI admission rebuilds per batch with history entries winning over the released ref, the daemon rebuilds per runToolCalls, headless seeds at run start — so the R23-30 surface-local release of a gate-rejected wrapper call lost to the history re-seed on the very next admission: on providers that reuse tool-call ids ({name}_{index} restarting at 0) the instructed identical re-issue was suppressed as "Duplicate provider tool call id", and a further re-issue tripped the repeated-duplicate breaker (GLOBAL_TOOL_CALL_DUPLICATE) — the deferred tool never executed despite the model following the rejection text. Skip user-turn functionResponse parts whose response.error is set when building the handled map: an error-answered call never executed, and an identical re-issue is the model's retry — on id-reusing providers its ONLY retry, since the model cannot mint a new id. Non-error answers still mark the id handled, so once the instructed retry succeeds, later identical re-issues are still suppressed; within a run the admission-time recording continues to cover repeats. The R23-30 surface releases remain as complementary machinery. Tests: real-GeminiChat coverage that an error-only answer leaves the id unhandled (pre-fix it was handled and the re-issue suppressed) and that an error-then-success pair marks the id handled from the success response only. --- packages/core/src/core/geminiChat.test.ts | 111 ++++++++++++++++++++++ packages/core/src/core/geminiChat.ts | 18 +++- 2 files changed, 127 insertions(+), 2 deletions(-) diff --git a/packages/core/src/core/geminiChat.test.ts b/packages/core/src/core/geminiChat.test.ts index 215fd0788f7..aa32eb88b77 100644 --- a/packages/core/src/core/geminiChat.test.ts +++ b/packages/core/src/core/geminiChat.test.ts @@ -5861,6 +5861,117 @@ describe('GeminiChat', async () => { getToolCallFingerprint('read_file', { file_path: 'a.ts' }), ); }); + + it('does not mark a call handled when its only response is an error (R24-1)', () => { + // R24-1: the #6721 gate's rejection is an error functionResponse that + // carries the SAME id as the rejected wrapper call and instructs the + // model to re-issue it.

Two confirmed fail-open triggers: 1. A carrying send blocked by a UserPromptSubmit hook decision (ToolResult is not in client.ts's exempt list) returns without pushing; any later send that pushes (a drain item, a stalled-teammate status drain, goal continuation) overwrites the baseline, the settle computes pushed=true against the WRONG send and drops the armed snapshot without restoring. 2. The structured-output early return exits before any carrying send. With a real tool literally named structured_output registered (the collision the budget-exemption comment acknowledges) and no --json-schema, the capture is ungated by structuredOutputActive and the run returns emitStructuredSuccess(); the finally-settle then compared against the producing send's baseline, which HAD pushed, and kept the unbacked marks. A batch whose committed marks survive with no schema in model context is the fail-open the #6721 gate exists to prevent; in reusable stream-json sessions the registry outlives the run. Fix (mirrors Session.ts's accept/fail-at-the-boundary pattern): settle the armed snapshot immediately after every sendMessageStream is consumed — main loop and drain-item loop — so the decision uses the carrying send's own baseline before any other send can overwrite it. armPresentationLedgerRollback additionally invalidates the baseline when it arms, so any exit between arm and the next send (structured-output early return, turn-limit, abort) restores fail-closed instead of inheriting the producing send's pushed baseline; both structured-output early-return sites force-settle explicitly. Tests (beside the three R23-33 tests): blocked carry followed by a pushing teammate-status drain restores exactly once at the blocked send's boundary (pre-fix: 0 restores, mark survived); the structured_output-collision early return restores the unbacked mark after exactly one send (pre-fix: 0 restores). --- packages/cli/src/nonInteractiveCli.test.ts | 227 +++++++++++++++++++++ packages/cli/src/nonInteractiveCli.ts | 30 +++ 2 files changed, 257 insertions(+) diff --git a/packages/cli/src/nonInteractiveCli.test.ts b/packages/cli/src/nonInteractiveCli.test.ts index 82a2b83ade0..7937f237b53 100644 --- a/packages/cli/src/nonInteractiveCli.test.ts +++ b/packages/cli/src/nonInteractiveCli.test.ts @@ -3279,6 +3279,233 @@ describe('runNonInteractive', () => { expect(restoreSpy).not.toHaveBeenCalled(); }); + it('restores at the blocked carrying send even when a later send pushes (R24-2)', async () => { + // R24-2 trigger 1: settlement used ONE shared push-count baseline + // that every send overwrote.

Wildcard/no-tool-config subagents and teammates declare hidden deferred tools directly (agent-core prepareTools uses getFunctionDeclarations({ includeDeferred: true })), and explicit-tool-list subagents declare exactly the names they list (getFunctionDeclarationsFiltered applies no shouldDefer filter); nothing reveals those tools in the registry at launch, and tool_call is excluded from subagents (EXCLUDED_TOOLS_FOR_SUBAGENTS). So select: reported a declared, directly-callable tool as "not available ... only the main session can route (via tool_call)" — both clauses false, and contradicting the tool's own description. prepareTools now records the prepared declaration names on the agent's context frame (AgentContext.declaredToolNames, patched in place so the whole frame sees it across awaits — an enterWith replacement would not reach the code resuming after await prepareTools()). The select: gate skips the block when the tool is in the recorded set: registry-hidden-but- context-declared names are re-inspectable like any declared tool, returned without the tool_call footer and without proxy presentations (subagents call the target directly).

Neither is true at this head. `proxySchemaPresentations` is alive in the registry, and `tool_call` still refuses a target whose mark is missing or whose schema fingerprint has moved — issue #6721's fail-closed gate against routing guessed or stale arguments. What this branch removed is narrower: the *reminder re-injection* paths that kept re-announcing the catalog into conversation history (`buildDeferredToolsReminder`, the added/changed MCP tool reminders, and the `client.ts` bookkeeping behind them). The catalog now lives in `tool_search`'s own description, rebuilt from the live registry on every declaration read, so nothing has to be restored after compression or resume. The ledger is a different mechanism with a different job, and conflating the two read as if the safety gate had been deleted. Correct the doc, and document the ledger's lifecycle explicitly: commit only after the carrying `tool_search` result enters active history, roll back a failed send, gate a sequential batch against a pre-batch snapshot so a sibling `tool_search` cannot self-authorize a `tool_call`, and clear on every history mutation that can evict a tool result. Also refresh descriptions the reminder removal left stale: comments in four files still enumerated "mid-history MCP added-tool reminders" and "resume-restored deferred schemas" as live history entry kinds, three references still named the renamed `resolveDeferredToolsForReminder`, the subagent test's header miscounted the reminder parts it guards, and the profiler and fork-resume docs still listed a deferred reminder stage that no longer exists.
