## Why
Unused imports in `core/tests/suite/unified_exec.rs` in the Windows
build were not caught by Bazel CI on
https://github.com/openai/codex/pull/18096. I spot-checked
https://github.com/openai/codex/actions/workflows/rust-ci-full.yml?query=branch%3Amain
and noticed that builds were consistently red. This revealed that our
Cargo builds _were_ properly catching these issues, identifying a
Windows-specific coverage hole in the Bazel clippy job.
The Windows Bazel clippy job uses `--skip_incompatible_explicit_targets`
so it can lint a broad target set without failing immediately on targets
that are genuinely incompatible with Windows. However, with the default
Windows host platform, `rust_test` targets such as
`//codex-rs/core:core-all-test` could be skipped before the clippy
aspect reached their integration-test modules. As a result, the imports
in `core/tests/suite/unified_exec.rs` were not being linted by the
Windows Bazel clippy job at all.
The clippy diagnostic that Windows Bazel should have surfaced was:
```text
error: unused import: `codex_config::Constrained`
--> core\tests\suite\unified_exec.rs:8:5
|
8 | use codex_config::Constrained;
| ^^^^^^^^^^^^^^^^^^^^^^^^^

= note: `-D unused-imports` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unused_imports)]`

--> core\tests\suite\unified_exec.rs:14:5

```
## What changed
- Run the Windows Bazel clippy job with the MSVC host platform via
`--windows-msvc-host-platform`, matching the Windows Bazel test job.
This keeps `--skip_incompatible_explicit_targets` while ensuring Windows
`rust_test` targets such as `//codex-rs/core:core-all-test` are still
linted.
- Remove the unused imports from `core/tests/suite/unified_exec.rs`.
- Add `--print-failed-action-summary` to
`.github/scripts/run-bazel-ci.sh` so Bazel action failures can be
summarized after the build exits.
## Failure reporting
Once the coverage issue was fixed, an intentionally reintroduced unused
import made the Windows Bazel clippy job fail as expected. That exposed
a separate usability problem: because the job keeps `--keep_going`, the
top-level Bazel output could still end with:
```text
ERROR: Build did NOT complete successfully
FAILED:
```
without the underlying rustc/clippy diagnostic being visible in the
obvious part of the GitHub Actions log.
To keep `--keep_going` while making failures actionable, the wrapper now
scans the captured Bazel console output for failed actions and prints
the matching rustc/clippy diagnostic block. When a diagnostic block is
found, it is emitted both as a GitHub `::error` annotation and as plain
expanded log output, rather than being hidden in a collapsed group.
## Verification
To validate the CI path, I intentionally introduced an unused import in
`core/tests/suite/unified_exec.rs`. The Windows Bazel clippy job failed
as expected, confirming that the integration-test module is now covered
by Bazel clippy. The same failure also verified that the wrapper
surfaces the matching clippy diagnostics directly in the Actions output.
## Summary
- Normalize deferred MCP and dynamic tools into `ToolSearchEntry` values
before constructing `ToolSearchHandler`.
- Move the tool-search entry adapter out of `tools/handlers` and into
`tools/tool_search_entry.rs` so the handlers directory stays focused on
handlers.
- Keep `ToolSearchHandler` operating over one generic entry list for
BM25 search, namespace grouping, and per-bucket default limits.
## Why
Follow-up cleanup for #17849. The dynamic tool-search support made the
handler juggle source-specific MCP and dynamic tool lists, index
arithmetic, output conversion, and namespace emission. This keeps source
adaptation outside the handler so the search loop itself is smaller and
source-agnostic.
## Validation
- `just fmt`
- `cargo test -p codex-core tools::handlers::tool_search::tests`
- `git diff --check`
- `cargo test -p codex-core` currently fails in unrelated
`plugins::manager::tests::list_marketplaces_ignores_installed_roots_missing_from_config`;
rerunning that single test fails the same way at
`core/src/plugins/manager_tests.rs:1692`.

Summary
- replace the thread/read persisted-load helper with
ThreadStore::read_thread
- move SQLite/rollout summary, name, fork metadata, and history loading
for persisted reads into LocalThreadStore
- leave getConversationSummary unchanged for a later PR
Context
- Replaces closed stacked PR #18232 after PR #18231 merged and its base
branch was deleted.
## TL;DR
- Adds a second Plan Mode handoff: implement the approved plan after
clearing context.
- Keeps the existing same-thread `Yes, implement this plan` action
unchanged.
- Reuses the `/clear` thread-start path and submits the approved plan as
the fresh thread's first prompt.
- Covers the new popup option, event plumbing, initial-message behavior,
and disabled states in TUI tests.
## Problem
Plan Mode already asks whether to implement an approved plan, but the
only affirmative path continues in the same thread. That is useful when
the planning conversation itself is still valuable, but it does not
support the workflow where exploratory planning context is discarded and
implementation starts from the final approved plan as the only
model-visible handoff.

## Mental model
There are now two implementation choices after a proposed plan. The
existing choice, `Yes, implement this plan`, is unchanged: it switches
to Default mode and submits `Implement the plan.` in the current thread.
The new choice, `Yes, clear context and implement`, treats the proposed
plan as a handoff artifact. It clears the UI/session context through the
same thread-start source used by `/clear`, then submits an initial
prompt containing the approved plan after the fresh thread is
configured.
The important distinction is that the new path is not compaction. The
model receives a deliberate implementation prompt built from the
approved plan markdown, not a summary of the previous planning
transcript. Both implementation choices require the Default
collaboration preset to be available, so the popup does not offer a
coding handoff when the fresh thread would fall back to another mode.
## Non-goals
This change does not alter `/clear`, `/compact`, or the existing
same-context Plan Mode implementation option. It does not add protocol
surface area or app-server schema changes. It also does not carry the
previous transcript path or a generated planning summary into the new
model context.
## Tradeoffs
The fresh-context option relies on the approved plan being sufficiently
complete. That matches the Plan Mode contract, but it means vague plans
will produce weaker implementation starts than a compacted transcript
would. The upside is that rejected ideas, exploratory dead ends, and
planning corrections do not leak into the implementation turn.
The current implementation stores the latest proposed plan in
`ChatWidget` rather than deriving it from history cells at selection
time. This keeps the popup action simple and deterministic, but it makes
the cache lifecycle important: it must be reset when a new task starts
so an old plan cannot be submitted later.
## Architecture
The TUI stores the most recent completed proposed-plan markdown when a
plan item completes. The Plan Mode approval popup uses that cache to
enable the fresh-context option and to build a first-turn prompt that
instructs the model to implement the approved plan in a fresh context.
Selecting the new option emits a TUI-internal
`ClearUiAndSubmitUserMessage` event. `App` handles that event by reusing
the existing clear flow: clear terminal state, reset app UI state, start
a new app-server thread with `ThreadStartSource::Clear`, and attach a
replacement `ChatWidget` with an initial user message. The existing
initial-message suppression in `enqueue_primary_thread_session` ensures
the prompt is submitted only after the new session is configured and any
startup replay is rendered.
## Observability
The previous thread remains resumable through the existing clear-session
summary hint. There is no new telemetry or protocol event for this path,
so debugging should start at the TUI event boundary: confirm the popup
emitted `ClearUiAndSubmitUserMessage`, confirm the app-server thread
start used `ThreadStartSource::Clear`, then confirm the fresh widget
submitted the initial user message after `SessionConfigured`.
## Tests
The Plan Mode popup snapshots cover the new option and preserve the
original option as the first/default action. Unit coverage verifies the
original same-context option still emits `SubmitUserMessageWithMode`,
the new option emits `ClearUiAndSubmitUserMessage` with the approved
plan embedded verbatim, and the clear-context option is disabled when
Default mode is unavailable or no approved plan exists. The broader
`codex-tui` test package passes with the updated fresh-thread
initial-message plumbing.
Rename `no_memories_if_mcp_or_web_search` →
`disable_on_external_context` with backward compatibility
While doing so, we add a key alias system on our layer merging system.
What we try to avoid is a case where a company managed config use an old
name while the user has a new name in it's local config (which would
make the deserialization fail)
