…rification Adds devlog/_plan/260813_routed_tool_discovery_profiles: the research, roadmap, prototypes and recorded results for a route-scoped tool-discovery compatibility profile that preserves PR #1596 defaults while giving a proven-bad route an explicit escape hatch. The bundle was authored without a mounted checkout, so 094_landing_verification_pass.md re-verifies every load-bearing claim against this worktree, the upstream codex-rs source (/Users/jun/Developer/codex, main @ 4462b9dee) and live GitHub state, and records eight corrections applied in place to 001/003/004/010/013/014: - supports_search_tool is gated upstream by a second conjunct (namespace_tools_enabled, spec_plan.rs:330), so it is not the sole switch. - Under code_mode_only, MCP tools are installed on the V8 tools/ALL_TOOLS globals in BOTH modes (globals.rs:15); direct only moves full schemas into exec.description at the measured payload cost. The override is a comprehension and compatibility lever, not a reachability fix. - CatalogModel lives in src/codex/catalog/parsing.ts:94, not src/types.ts. - modelRecordValue() does not match dated -YYYYMMDD variants; the date-compatible key promise is withdrawn. - providerConfigSchema is .passthrough() with no .catch(), so both config validation halves must be built explicitly. - src/codex/catalog/aggregation.ts was missing from the touch map. - The parallelToolCalls precedent covers the template path only. - The Cursor fence resolves from slug on one path and provider identity on the other, the unresolved #1596 P2; this unit closes it rather than reproducing it. Docs only: nothing in the build, typecheck or test path reads from devlog/. Verification: bun test tests/repo-hygiene.test.ts (11 pass / 0 fail), bun run privacy:scan (passed), shasum -a 256 -c SHA256SUMS (all OK).
An independent audit of 094_landing_verification_pass.md returned FAIL over four rounds. This closes every blocker it raised. Scope of the central claim (correction 2). "Under code_mode_only MCP tools stay callable in both modes" was unconditional and unsupported. It now reads "an eligible MCP tool", with a table of the three flag-independent removal paths that an override cannot repair: direct_only_tool_namespaces -> DirectModelOnly (spec_plan.rs:210), excluded_tool_namespaces (spec_plan.rs:444), and MCP/App policy filtering applied before exposure classification (mcp_tool_exposure.rs:20). The flag also drives tool_search construction and the deferred-guidance text, so exec.description is not the only delta. Code Mode vs CodeModeOnly. The isolate is built for both (`!matches!(tool_mode, CodeMode | CodeModeOnly)`, spec_plan.rs:459); only ToolMode::Direct has none. 000, 004, 010, 020 and 094 are aligned on this, and 020's differential expectation no longer claims the delta is confined to exec.description. Cursor fence (unresolved #1596 P2). 012 no longer reproduces the slug check. Both construction paths now specify one shared isCursorRoute(entry, providerId) helper that prefers provider identity and falls back to the slug prefix only when no CatalogModel is available. The third parameter becomes an options object { toolDiscoveryMode, providerId } so the existing public callers (src/codex/catalog.ts re-export, tests/parallel-tool-calls-optin.test.ts) keep their positional arguments. 003 updated to match. Draft applicator. patches/apply-draft.mjs writes that same asymmetry while printing "draft seams: OK", because --check asserts seam presence and not policy. Every instruction to run it is withdrawn: the patches README is now marked ARCHIVAL, the Korean summary's application block is removed, and the script's own docblock opens with ARCHIVAL - KNOWN-DEFECTIVE - DO NOT EXECUTE. The body is kept as the seam map it is. Config contract. 011 now requires a load-path warning on degradation and descriptor-before-read rejection of accessor/prototype-polluted model maps, both as first-PR work with tests in 020. Upstream paths. 004 corrected to codex-rs/code-mode/, with spec_plan_tests.rs acknowledged as existing. Verification: independent reviewer VERDICT PASS after four repair rounds; bun test tests/repo-hygiene.test.ts (11 pass / 0 fail); bun run privacy:scan passed; node --check patches/apply-draft.mjs passed; SHA256SUMS regenerated and fully verified.

📝 WalkthroughWalkthroughThis PR adds a routed tool-discovery investigation bundle. It documents profile resolution, catalog propagation, protocol conformance, bounded meta-tools, benchmarks, rollout controls, rollback procedures, and validation limits.

Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟡 Moderate · up to The PR adds documentation and prototypes, but current guidance still permits reproducing a known-defective patch and leaves route classification and sensitive-artifact handling inconsistent; this could mislead implementation or expose data if followed.

Because this section explicitly documents how the unshipped first-PR validator can execute attacker-controlled accessors and prescribes the pre-disclosure fix, committing it under the public devlog/_plan tree exposes security working notes before the implementation ships. Move this analysis to .tmp/ or another scratch location and publish only the fix, regression test, and post-release outcome.

Anyone following the master plan cannot locate any of these five artifacts: a repo-wide filename search finds only these references. The committed files are instead 0001-add-tool-discovery-module.patch, 0002-focused-test-plan.patch, run-repo-validation.sh, prototype-test.txt, and the two size-specific payload-benchmark-{250,1000}.json files, so update this inventory to point to the actual executable evidence.

This source link uses codex-rs/code-mode-runtime, but the bundle's own verified correction in 004_upstream_codex_code_mode.md:32-35 says that path is stale and that the inspected crate is codex-rs/code-mode. As written, the primary-evidence index sends implementers to the wrong upstream path; update the URL to the verified code-mode/src/runtime/globals.rs location.

In `@devlog/_plan/260813_routed_tool_discovery_profiles/000_master_plan.md`:
- Around line 159-169: Update the “Executable supplements” section in the master
plan to list only executable prototypes, tests, benchmarks, and validation
scripts; remove archival patch files from that section. Rebuild the inventory
using the current manifest so patch names match the supplied bundle, and place
archival patches in a separate clearly labeled section.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/012_phase1_catalog_patch.md`:
- Around line 65-68: Update isCursorRoute in
devlog/_plan/260813_routed_tool_discovery_profiles/012_phase1_catalog_patch.md:65-68
to validate both provider and adapter/config identity on every route, and update
its callers to pass that identity. In
devlog/_plan/260813_routed_tool_discovery_profiles/010_phase1_profile_resolver.md:44-49,
align the resolver contract with the shared helper and add coverage for Cursor
using a custom provider name.
- Around line 52-60: Update
devlog/_plan/260813_routed_tool_discovery_profiles/012_phase1_catalog_patch.md:52-60
to identify and test namespace_tools_enabled alongside supports_search_tool as
part of the deferred-discovery contract. Update
devlog/_plan/260813_routed_tool_discovery_profiles/000_master_plan.md:35-45 to
label the current-state bullets as catalog metadata rather than the complete
runtime gate; update
devlog/_plan/260813_routed_tool_discovery_profiles/006_architecture_invariants.md:10-21
to include both predicates in INV-2; and update
devlog/_plan/260813_routed_tool_discovery_profiles/009_open_questions_and_evidence_gaps.md:7-25
to record namespace_tools_enabled in the `#1522` reproduction.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/021_catalog_test_cases.md`:
- Around line 21-38: Update the catalog test assertions to pin hosted-search
invariants for every required case: assert presence for C01 and C02, and absence
for C05, C06, and C09. In the C06 assertions, also verify the expected Cursor
warning or diagnostic, while retaining the existing explicit tool_mode and
search-tool checks.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/022_config_and_precedence_tests.md`:
- Around line 57-59: Add security fixtures and assertions for the validation
path covering both an own getter that throws if accessed and an inherited
getter/prototype property. Ensure validation rejects each input before reading
attacker-controlled properties, and verify the getters are never invoked while
preserving the existing null-prototype and own “__proto__” coverage.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/023_backward_compatibility_tests.md`:
- Around line 29-31: Add an end-to-end downgrade round-trip test covering
unknown routed-discovery provider fields: seed fields absent from the older
schema, save an unrelated configuration change through the older writer, reload
the persisted configuration, and assert those fields are preserved exactly. Use
providerConfigSchema and the complete persisted-object serialization path as the
compatibility targets; if preservation fails, document downgrade behavior as
lossy and remove the preservation claim instead.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/024_catalog_cache_identity_tests.md`:
- Around line 7-21: Update Test A to explicitly assert that configurations using
“deferred” and “direct” produce different fingerprint or gather keys, proving
discovery policy affects deduplication identity. If the key is private,
instrument the admission layer instead and assert that two distinct flights are
created, while confirming each result retains its corresponding mode.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/025_combo_policy_tests.md`:
- Around line 3-9: Align the combo tool-discovery mode contract across the
composition rule, deriveComboToolDiscoveryMode, and tests: either consistently
accept member objects with an explicit normalization step to mode strings, or
consistently accept mode-string arrays. Mark the composition snippet as
pseudocode if normalization remains, and ensure the design and tests use the
same input shape.
- Around line 34-41: Expand the alias coverage cases to assert each form
resolves to the same canonical combo identity and preserves the configured combo
selectors. Include normal combo/<id>, bare alias, slashed alias, and permitted
explicit native alias, while validating the distinct filtering behavior for bare
public aliases versus native disabled-model identifiers.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/030_phase3_protocol_conformance.md`:
- Around line 9-15: Update the conformance identity definition so each result
includes provider identity and the resolved model ID, preventing profile
collisions across providers or models. Also include fingerprints for route,
account, and any configuration that affects discovery behavior, while retaining
the existing client surface, version, adapter, protocol, and OpenCodex version
fields.
- Around line 38-50: Update the VERIFIED eligibility and automatic
profile-selection rules to require unexpired evidence, so expired artifacts
cannot be selected even when their state is VERIFIED. Extend the result-state or
protocol-conformance cases with an expiry validation case covering expired
evidence being rejected.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/031_responses_lite_additional_tools.md`:
- Around line 21-30: Extend the request translation tests to cover
request-scoped tool_choice after merging top-level tools with nested
additional_tools. Add a fixture selecting a tool declared in additional_tools,
then assert its translated qualified identity is preserved exactly once.
- Around line 32-37: Define one deterministic policy for duplicate
additional_tools entries and incompatible tool kinds, including precedence and
explicit failure behavior, in
devlog/_plan/260813_routed_tool_discovery_profiles/031_responses_lite_additional_tools.md
lines 32-37. Align the round-trip validation expectations in
devlog/_plan/260813_routed_tool_discovery_profiles/032_custom_namespace_roundtrip.md
lines 29-36 with that policy, covering plain-name, qualified-name,
custom/function, and ambiguous suffix collisions so translated-name dispatch is
order-independent.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/032_custom_namespace_roundtrip.md`:
- Around line 38-47: Update the response tests to require custom lifecycle
restoration only for non-forward passthrough routes, where routedCustomToolNames
is available. Add a forward-auth negative case asserting the documented
unsupported behavior, while preserving the existing streaming and non-streaming
coverage for supported routes.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/033_tool_search_history_and_compaction.md`:
- Around line 23-34: Update the persisted tool-reference resume flow to store
the discovery identity, including manifest/profile fingerprint information, and
validate it against the current manifest before reuse. Treat unchanged qualified
names with changed schemas or providers as incompatible, and return the existing
structured unavailable result for both missing and incompatible references.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/035_failure_injection.md`:
- Around line 28-30: Make the fail-closed rule executable by explicitly
prioritizing the direct profile only when the route supports all deferred
declarations within its limits; otherwise stop before dispatch and return a
structured capability error. Define the fallback behavior for unsupported or
oversized direct declarations, and ensure the request path asserts that no
upstream request is sent.
- Around line 16-26: Update the failure-classification flow to record the
advertised tool set, tool_choice, route/profile, and translator output, then use
this evidence to distinguish a normal model decision from route advertisement or
translator failures when no tool call is returned. Preserve explicit diagnostics
or fallback for protocol and execution failures.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/040_phase4_live_e2e.md`:
- Around line 9-19: Update the live-capture plan for the bundle artifacts to
define an allowlist and mandatory redaction before persisting client.log,
proxy.log, transcript.redacted.jsonl, all-tools.txt, and the other outputs; use
synthetic inputs where feasible, run secret and PII scans before retention, and
document retention and deletion rules.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/042_codex_app_deepseek_browser.md`:
- Around line 32-49: Extend the Prompt battery capture and validation around the
browser tool sequence to assert the deterministic local page title, expected DOM
fact, screenshot artifact, and continuity of the second browser action in the
same session. Base each oracle on actual tool results rather than the model’s
final text, while preserving the existing discoverability and tool-call capture
checks.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/043_cursor_and_direct_bounded.md`:
- Around line 29-40: Update the direct-mode safety policy to include the
existing greater-than-256 KiB total request-body threshold alongside mcpMaxTools
and mcpMaxSchemaBytes. Define that the bound covers exec.description and every
serialized request field, and specify whether exceeding it fails explicitly or
routes through meta-tools; do not allow silent truncation without has_more or
diagnostics.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/044_weak_model_meta_tool_fallback.md`:
- Around line 23-30: Define the evaluation protocol for the 30-task comparison:
fix the task set and ordering, compare the same tasks across paired profiles,
and document the minimum required gain plus the confidence criterion before
switching profiles. Apply this rule consistently to the related sections 41–44.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/045_dynamic_mcp_refresh.md`:
- Around line 5-16: Update the dynamic MCP refresh scenario to register and
assert the canonical namespaced tool identifier, treating “mcp__” as part of the
namespace and constructing the wire name as namespace plus “__” plus name.
Replace the unnamespaced dynamic_echo references in the registration, exact-name
search, call, removal, and subsequent assertions while preserving the existing
refresh sequence.
- Around line 5-16: Update the dynamic MCP refresh scenario to explicitly assert
that receiving notifications/tools/list_changed causes the client to issue a
fresh tools/list request and advance the side-index generation before searching
or calling the newly registered tool. Ensure the test cannot pass using only a
locally mutated index, while preserving the existing add, verify, call, remove,
and recheck sequence.
- Around line 9-24: Update the dynamic MCP refresh test so post-removal fresh
search asserts that the removed tool is absent, while the structured unavailable
result is tested separately by replaying the previously selected tool name or
issuing a stale call. Do not require the removed tool to appear in fresh search
results.
- Around line 18-24: Update the expected cache behavior for the dynamic MCP
refresh scenarios to distinguish deferred and direct modes: deferred side-index
refreshes should preserve the top-level manifest and cached prefix, while
direct-mode MCP declaration mutations in exec.description should invalidate the
cached prefix. Add separate cases documenting the exact manifest mutation and
resulting cache effect.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/051_benchmark_methodology.md`:
- Around line 3-29: Update the benchmark workflow around payload-benchmark.mjs
so every JSON result and summary row records its fixture inputs: schema shape,
description length, schema bytes, namespace distribution, and serialization
revision. Include these fields separately for the 250-tool and 1,000-tool
scenarios so the reported values remain reproducible across the required
benchmark cases.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/052_acceptance_thresholds.md`:
- Around line 31-35: Update the Acquisition section to define a reproducible
evaluation gate: specify the fixed deterministic task corpus, sample count,
success and failure criteria, denominator for the 95% comparison, and the
numeric cost delta that qualifies as “materially outperform.” Add measurable
pass criteria for both the deferred/meta profile threshold and the direct-mode
cost alternative.
- Around line 11-15: Clarify the warning thresholds in the acceptance criteria
by defining exactly what serialized data counts toward schema bytes and
request-body bytes, including names, descriptions, wrappers, and instructions.
Specify UTF-8 measurement, the KiB base, and whether each boundary is strict or
inclusive, using the same byte-calculation method as
051_benchmark_methodology.md.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/053_prompt_cache_scenarios.md`:
- Around line 16-22: Clarify the cache-chain assertion by naming the exact
provider metric fields, units, request boundary, and allowed tolerance for
comparing the next cache read against the previous cache read plus creation.
Define expected TTL-expiry behavior separately from the failure condition for
prefix mutation, including the threshold for a large unexplained collapse.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/059_phase5_exit_gate.md`:
- Line 10: Update the checklist criterion for separating synthetic and live
results by recording the evidence from results/benchmark-summary.md lines 3–4,
mark it complete, and link that evidence; if the evidence is insufficient,
document why the criterion remains unaccepted.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/061_meta_tool_contract.md`:
- Around line 7-24: Use the canonical qualified namespace form in the
tool-discovery contract: change the request namespace from browser to
mcp__browser and preserve that same value in the response. If bare namespaces
must remain accepted, add explicit normalization before filtering and
serialization.
- Around line 54-56: Update the response-contract section to define explicit
versioned envelopes for ocx_tool_search, ocx_tool_describe, and ocx_tool_call,
including contract version and indexGeneration fields where required. Add
expectedIndexGeneration stale-generation behavior: return a bounded typed error
and do not dispatch the requested tool when the generation is stale.
- Around line 36-52: Define one canonical schema and name-normalization path for
ocx_tool_describe and ocx_tool_call. Ensure ocx_tool_describe returns schemas
from the authorized canonical catalog, while ocx_tool_call validates against
that schema, resolves the exact qualified name before authorization and
dispatch, and reuses the existing mappings in live-transport.ts and
protobuf-events.ts. Do not use cursorToolInputSchema() as the execution schema;
preserve cursorToolArgNormalizeSchema() so shell_command produces canonical
command arguments and aliases cannot bypass authorization.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/062_meta_tool_security.md`:
- Around line 3-15: Update ocx_tool_call to resolve the caller’s current
filtered authorized catalog immediately before execution, rather than trusting
prior search or describe results. Reapply server allowlists, per-tool
permissions, network policy, pre-call hooks, logging, and rate limits through
the existing execution path, and fail closed when authorization no longer
permits the call.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/063_meta_tool_ranking.md`:
- Around line 17-25: Bind the opaque nextCursor used by the pagination contract
to the indexed snapshot, including generation and relevant query, namespace
filter, and ranking version; validate these bindings on subsequent requests and
reject stale or mismatched cursors rather than mixing snapshots. Update
065_meta_tool_tests.md to cover cursors invalidated by tools/list_changed and
mismatched request parameters.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/064_meta_tool_integration.md`:
- Around line 3-13: Apply the current request’s tool_choice and allowed-tool
predicates when searching the session-scoped index, rather than relying on
authorization captured when it was built. Revalidate those same restrictions
immediately before ocx_tool_call executes, preventing denied tools from being
discovered or called through stale catalog entries; preserve the unified
request-wide tool set from tools and additional_tools.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/065_meta_tool_tests.md`:
- Around line 36-38: Update the E2E test plan to normalize authorization results
from direct, Code Mode, and meta-tool profiles to the underlying qualified tool
name, allow/deny decision, policy reason, and hook outcome before comparison.
Assert these normalized authorization values alongside the identical final
external side effect, rather than comparing profile-specific top-level
declarations.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/072_canary_matrix.md`:
- Around line 10-11: Update the canary matrix rows for Codex App and Codex CLI
to contain six cells matching the header, adding the missing column separator
and verifying that each row places the correct value under Profile and Cadence.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/073_config_migration_and_docs.md`:
- Around line 23-31: Update the provider-wide diagnostic override example to
nest routedToolDiscovery under providers.deepseek, matching the
OcxProviderConfig contract; do not leave it as a root-level field.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/074_support_runbook.md`:
- Line 19: Update the support runbook entry to reference the documented fields
supports_search_tool, routedToolDiscovery, and modelRoutedToolDiscovery instead
of “search false” or generic direct mode. Instruct operators to inspect those
exact values and clarify whether supports_search_tool=false affects tool
exposure or only hosted search behavior.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/083_incident_report_template.md`:
- Around line 18-28: Update the incident report template’s Minimal prompt and
Redaction statement sections to require synthetic or minimally redacted
excerpts, prohibit credentials, tokens, and raw prompt content, and require
authors to list every removed field; define an explicit confirmation format
consistent with the template.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/092_definition_of_done.md`:
- Around line 3-9: Replace the vague “full suite green” criterion in the Phase 1
checklist with either the exact future test suite and executable
command/artifact, including the required verification details, or explicitly
mark the criterion not applicable to this documentation-only PR.
In `@devlog/_plan/260813_routed_tool_discovery_profiles/KOREAN_SUMMARY.md`:
- Line 27: Update the relevant summary and source-reference entries to include
objective issue `#1587` while preserving historical remediation PR `#1529` in
002_incident_history_1522_1529_1596.md and SOURCE_INDEX.md; then regenerate
SHA256SUMS for all changed files.
In
`@devlog/_plan/260813_routed_tool_discovery_profiles/patches/0002-focused-test-plan.patch`:
- Around line 44-50: Extend the test for resolveRoutedToolDiscoveryMode to cover
both Cursor classification inputs: verify the hard-fence when the provider name
is "cursor" and when adapter is "cursor", and assert that each

- Around line 39-47: Add a test covering the provider-name hard-fence branch in
resolveRoutedToolDiscoveryMode: use providerName "cursor" with a non-Cursor
adapter and assert the same direct mode and "cursor-hard-fence" source,
preserving the existing adapter-branch test.
- Around line 50-53: Add migration coverage to the “combo direct member wins”

Do not present archival patches as executable supplements.
The PR objective says the draft patches are archival and their execution instructions are withdrawn. This section still labels them executable and lists names that do not match the supplied bundle, such as patches/0001-routed-tool-discovery-profile.patch versus patches/0001-add-tool-discovery-module.patch. Split executable prototypes and validation scripts from archival patches, then update the inventory from the current manifest.

Pin every hosted-search invariant in the assertions.
The matrix requires hosted search for C01 and C02 and requires its absence for C05, C06, and C09. The exact assertion examples show only the direct-mode presence check. Add explicit presence or absence assertions for the default and Cursor cases. Assert the Cursor warning or diagnostic for C06 as well.

Cover both Cursor classification inputs.
The proposed resolver hard-fences when either the provider name or the adapter is "cursor". This test covers only the adapter branch. It also does not assert the warning emitted when deferred discovery is ignored. Add both assertions so a regression in provider-name routing or diagnostics cannot pass.

Use one Cursor-route classifier in both policy stages.
At Line 91, catalog policy uses only clone.slug. At Line 45, resolution uses providerName or adapter. A Cursor route without a cursor/ slug retains web_search_tool_type. A non-Cursor combo with a cursor/ alias can lose hosted-search metadata and force supports_search_tool=false.
Pass provider identity into applyRoutedToolDiscoveryPolicy(). Use one shared isCursorRoute() helper. Use the slug prefix only when provider identity is unavailable. This is the known asymmetry recorded in 094_landing_verification_pass.md Correction 8.

Use authoritative route and verified capability evidence.
profile-resolver.mjs:13-18 trusts isCursorSurface. A caller that supplies false can select native-tool-search or proxy-meta-tools for Cursor. Use the shared route classification as the hard fence.
profile-resolver.mjs:27-33 gates native discovery on only five booleans. The phase 3 contract also requires continuation, failure handling, dynamic refresh, compaction, resume, streaming/non-streaming parity, and authorization parity (030_phase3_protocol_conformance.md:25-36, 039_phase3_exit_gate.md:3-15). Require one VERIFIED conformance result, or add every required result to the gate.
profile-resolver.mjs:40-45 treats hasMetaToolSidecar as sufficient. Require verified search, describe, and call behavior, including bounds, cancellation, generation handling, and reuse of the caller's authorization path (061_meta_tool_contract.md:34-52, 062_meta_tool_security.md:3-32).
Extend prototype/tool-discovery-profile.test.mjs with a Cursor case that supplies all capabilities, one case for each missing native requirement, and meta-tool cases that lack each required contract result. The current tests cover only the complete native path, one incomplete native path with a sidecar, and the empty fallback.

Require fingerprint divergence, not only row divergence.
Line 21 allows the test to pass when the gather key is identical but returned rows differ by timing. That does not prove that discovery policy participates in deduplication identity. Assert that the two keys differ. If the key is private, instrument the admission layer and assert two distinct flights, then verify each result carries its own mode.

Align the combo input contract with the proposed resolver.
This rule reads member.toolDiscoveryMode from member objects. The proposed deriveComboToolDiscoveryMode contract and its test use mode strings such as ["deferred", "direct"]. Mark this as pseudocode with an explicit normalization step, or use one input shape in the design, prototype, and tests.

Define expected results for every alias form.
“Run the same cases” does not prove that each alias maps to the same canonical combo identity or preserves configured selectors. Based on learnings, provider-scoped enablement preserves configured combo selectors, and a bare public alias such as fast-chat is not necessarily a native disabled-model identifier. Assert canonical identity and filtering behavior for each alias form.

Align the direct-mode policy with the total request-byte threshold.
mcpMaxTools and mcpMaxSchemaBytes do not bound exec.description or other serialized fields. 052_acceptance_thresholds.md:9-15 already proposes a >256 KiB request body threshold. Reference that threshold here and define whether overflow fails or routes through meta-tools. Include exec.description and all request fields in the bound.

Cover both Cursor hard-fence branches.
The resolver fences Cursor when either providerName === "cursor" or provider.adapter === "cursor". This test covers only the adapter branch. Add a case with provider name cursor and a non-Cursor adapter.

Cover the undefined migration cases.
025_combo_policy_tests.md requires undefined + deferred and undefined + direct. This test covers only defined mode strings. Add both cases to verify migration behavior for providers without a model override.

Test catalog policy for a custom Cursor adapter.
Lines 66-74 only verify the resolver result. The supplied mvp-resolver.mjs policy classifies Cursor from entry.slug. Therefore, a route with adapter: "cursor" and a slug such as my-cursor/model still receives web_search_tool_type.
Extend this test to pass a my-cursor/... row through applyRoutedToolDiscoveryPolicy. Assert that it has supports_search_tool: false and no web_search_tool_type. Then make the policy use the same Cursor classifier as the resolver.

Withdraw the remaining draft-patch execution guidance.
The PR objective says the draft applicator is archival because it reproduces a known Cursor-path asymmetry. These files still direct readers to apply the draft and validate it. A reader can therefore reproduce the known defect in a clean dev worktree.

Verify SHA256SUMS in the bundle validator.
The bundle includes SHA256SUMS, but this script never checks it. A modified document, patch, or prototype can pass lines 19-20 without integrity validation.

Summary
devlog/_plan/260813_routed_tool_discovery_profiles: the research, roadmap, prototypes and recorded results for a route-scoped Codex tool-discovery compatibility profile. Docs only — nothing in the build, typecheck or test path reads fromdevlog/.094_landing_verification_pass.mdre-verifies every load-bearing claim against this worktree, the upstreamcodex-rssource and live GitHub state, and records the eight corrections that followed.Why this is worth reading before the code
The most consequential correction reframes what the feature is. Under
tool_mode = code_mode_only, upstream installs nested MCP tools on the V8tools/ALL_TOOLSglobals in both exposures (code-mode/src/runtime/globals.rs:15, fed fromspec_plan.rs:463). Whatsupports_search_toolchanges is where the schemas live — direct exposure embeds every declaration inexec.description, the measured 96,699 → 258,929 char turn-1 regression behind #1596 — plustool_searchconstruction and the deferred-guidance text.So a
directoverride is a comprehension and compatibility lever with a payload cost, not a reachability fix, and it cannot repair a tool removed bydirect_only_tool_namespaces,excluded_tool_namespaces, or MCP/App policy filtering, all independent of this flag.The eight corrections
supports_search_toolis gated by a second conjunct,namespace_tools_enabledspec_plan.rs:330globals.rs:15,mcp_tool_exposure.rs:35,code_mode.rs:644/:3248CatalogModellives inparsing.ts, nottypes.ts— following the docs literally would have created an import cycleparsing.ts:94modelRecordValue()does not match dated-YYYYMMDDvariants; the date-compatible key promise is withdrawnreasoning-effort.ts:49-62providerConfigSchemais.passthrough()with no.catch(), so both validation halves are new workconfig.ts:616-645aggregation.tswas missing from the touch map despite012specifying a combo ruleaggregation.ts:125-177parallelToolCallsprecedent covers the template path onlysync.ts:287,parsing.ts:293-306parsing.ts:395vssync.ts:312Correction 8 is a real behavior defect, not just a doc issue: a
