## Summary
Ad-hoc memory notes are written under `memories/extensions/ad_hoc/`, but
the consolidation agent only knows how to interpret an extension when
the extension folder has an `instructions.md`. Seed those instructions
from the memories write pipeline so an enabled memories startup creates
the expected ad-hoc extension layout automatically.
This also moves extension-specific write behavior behind a dedicated
`memories/write/src/extensions/` module. `ad_hoc` owns the seeded
instructions template, while the existing resource-retention cleanup
lives in its own `prune` module so future memory extensions can add
their own write-side setup without growing a flat helper file.
## Changes
- Seed `memories/extensions/ad_hoc/instructions.md` during eligible
memory startup without overwriting an existing file.
- Store the ad-hoc instructions template under
`memories/write/templates/extensions/ad_hoc/`, keeping ownership in
`codex-memories-write`.
- Split memory extension support into `extensions::ad_hoc` and
`extensions::prune`.
- Keep the existing old-resource pruning behavior unchanged.
## Verification
- `cargo test -p codex-memories-write`
- `bazel build //codex-rs/memories/write:write`

## Why
This bug is exposed by Guardian/auto-review approvals. With the managed
network proxy enabled, a blocked network request can be reported back
through the network approval service as an approval denial after the
command has already started. Before this change, the shell and unified
exec runtimes registered those network approval calls, but did not have
a way to observe an async proxy denial as a cancellation/failure signal
for the running process.
The result was confusing: Guardian/auto-review could correctly deny
network access, but the command path could keep running or unregister
the approval without surfacing the denial as the command failure.
## What Changed
- `NetworkApprovalService` now attaches a cancellation token to active
and deferred network approvals.
- Proxy-denial outcomes are recorded only for active registrations,
cancel the owning token, and are consumed when the approval is
finalized.
- The shell runtime combines the normal command timeout with the
network-denial cancellation token.
- Unified exec stores the deferred network approval object, terminates
tracked processes when the proxy denial arrives, and returns the denial
as a process failure while polling or completing the process.
- Tool orchestration passes the active network approval cancellation
token into the sandbox attempt and preserves deferred approval errors
instead of silently unregistering them.
- App-server `command/exec` now handles the combined
timeout-or-cancellation expiration variant used by the runtime.
## Verification
- `cargo test -p codex-core network_approval --lib`
- `cargo clippy -p codex-app-server --all-targets -- -D warnings`
- `cargo clippy -p codex-core --all-targets -- -D warnings`

## Why
Phase 2 still needs to choose the most relevant stage-1 memory outputs
by usage and recency, but exposing that ranking as the rendered
`raw_memories.md` order creates unnecessary large diff. Usage-count or
timestamp changes can reshuffle otherwise unchanged memories, making the
workspace diff noisy and giving the consolidation prompt a misleading
recency signal from file position.
This fix will reduce token consumption
## What Changed
- Keep the existing top-N Phase 2 selection ranking by `usage_count`,
`last_usage`, `source_updated_at`, and `thread_id`.
- Return the selected rows in stable ascending `thread_id` order before
syncing Phase 2 filesystem inputs.
- Update the memory README, raw memories header, and consolidation
prompt so they describe the stable order and tell the prompt to use
metadata and workspace diffs instead of file order as the recency
signal.
- Adjust the memory runtime tests to use deterministic thread IDs and
assert the stable return order separately from the ranked selection
semantics.
## Test Coverage
- Existing memory runtime tests in
`codex-rs/state/src/runtime/memories.rs` now cover the stable returned
ordering for Phase 2 inputs.
