## Why
We currently carry multiple permission-related concepts directly on
`Config` for shell/unified-exec behavior (`approval_policy`,
`sandbox_policy`, `network`, `shell_environment_policy`,
`windows_sandbox_mode`).
Consolidating these into one in-memory struct makes permission handling
easier to reason about and sets up the next step: supporting named
permission profiles (`[permissions.PROFILE_NAME]`) without changing
behavior now.
This change is mostly mechanical: it updates existing callsites to go
through `config.permissions`, but it does not yet refactor those
callsites to take a single `Permissions` value in places where multiple
permission fields are still threaded separately.
This PR intentionally **does not** change the on-disk `config.toml`
format yet and keeps compatibility with legacy config keys.
## What Changed
- Introduced `Permissions` in `core/src/config/mod.rs`.
- Added `Config::permissions` and moved effective runtime permission
fields under it:
- `approval_policy`
- `sandbox_policy`
- `network`
- `shell_environment_policy`
- `windows_sandbox_mode`
- Updated config loading/building so these effective values are still
derived from the same existing config inputs and constraints.
- Updated Windows sandbox helpers/resolution to read/write via
`permissions`.
- Threaded the new field through all permission consumers across core
runtime, app-server, CLI/exec, TUI, and sandbox summary code.
- Updated affected tests to reference `config.permissions.*`.
- Renamed the struct/field from
`EffectivePermissions`/`effective_permissions` to
`Permissions`/`permissions` and aligned variable naming accordingly.
## Verification
- `just fix -p codex-core -p codex-tui -p codex-cli -p codex-app-server
-p codex-exec -p codex-utils-sandbox-summary`
- `cargo build -p codex-core -p codex-tui -p codex-cli -p
codex-app-server -p codex-exec -p codex-utils-sandbox-summary`
`SandboxPolicy::ReadOnly` previously implied broad read access and could
not express a narrower read surface.
This change introduces an explicit read-access model so we can support
user-configurable read restrictions in follow-up work, while preserving
current behavior today.
It also ensures unsupported backends fail closed for restricted-read
policies instead of silently granting broader access than intended.
## What
- Added `ReadOnlyAccess` in protocol with:
- `Restricted { include_platform_defaults, readable_roots }`
- `FullAccess`
- Updated `SandboxPolicy` to carry read-access configuration:
- `ReadOnly { access: ReadOnlyAccess }`
- `WorkspaceWrite { ..., read_only_access: ReadOnlyAccess }`
- Preserved existing behavior by defaulting current construction paths
to `ReadOnlyAccess::FullAccess`.
- Threaded the new fields through sandbox policy consumers and call
sites across `core`, `tui`, `linux-sandbox`, `windows-sandbox`, and
related tests.
- Updated Seatbelt policy generation to honor restricted read roots by
emitting scoped read rules when full read access is not granted.
- Added fail-closed behavior on Linux and Windows backends when
restricted read access is requested but not yet implemented there
(`UnsupportedOperation`).
- Regenerated app-server protocol schema and TypeScript artifacts,
including `ReadOnlyAccess`.
## Compatibility / rollout
- Runtime behavior remains unchanged by default (`FullAccess`).
- API/schema changes are in place so future config wiring can enable
restricted read access without another policy-shape migration.
## Why
`codex-core` was being built in multiple feature-resolved permutations
because test-only behavior was modeled as crate features. For a large
crate, those permutations increase compile cost and reduce cache reuse.
## Net Change
- Removed the `test-support` crate feature and related feature wiring so
`codex-core` no longer needs separate feature shapes for test consumers.
- Standardized cross-crate test-only access behind
`codex_core::test_support`.
- External test code now imports helpers from
`codex_core::test_support`.
- Underlying implementation hooks are kept internal (`pub(crate)`)
instead of broadly public.
## Outcome
- Fewer `codex-core` build permutations.
- Better incremental cache reuse across test targets.
- No intended production behavior change.
# Memories migration plan (simplified global workflow)
## Target behavior
- One shared memory root only: `~/.codex/memories/`.
- No per-cwd memory buckets, no cwd hash handling.
- Phase 1 candidate rules:
- Not currently being processed unless the job lease is stale.
- Rollout updated within the max-age window (currently 30 days).
- Rollout idle for at least 12 hours (new constant).
- Global cap: at most 64 stage-1 jobs in `running` state at any time
(new invariant).
- Stage-1 model output shape (new):
- `rollout_slug` (accepted but ignored for now).
- `rollout_summary`.
- `raw_memory`.
- Phase-1 artifacts written under the shared root:
- `rollout_summaries/<thread_id>.md` for each rollout summary.
- `raw_memories.md` containing appended/merged raw memory paragraphs.
- Phase 2 runs one consolidation agent for the shared `memories/`
directory.
- Phase-2 lock is DB-backed with 1 hour lease and heartbeat/expiry.
## Current code map
- Core startup pipeline: `core/src/memories/startup/mod.rs`.
- Stage-1 request+parse: `core/src/memories/startup/extract.rs`,
`core/src/memories/stage_one.rs`, templates in
`core/templates/memories/`.
- File materialization: `core/src/memories/storage.rs`,
`core/src/memories/layout.rs`.
- Scope routing (cwd/user): `core/src/memories/scope.rs`,
`core/src/memories/startup/mod.rs`.
- DB job lifecycle and scope queueing: `state/src/runtime/memory.rs`.
## PR plan
## PR 1: Correct phase-1 selection invariants (no behavior-breaking
layout changes yet)
- Add `PHASE_ONE_MIN_ROLLOUT_IDLE_HOURS: i64 = 12` in
`core/src/memories/mod.rs`.
- Thread this into `state::claim_stage1_jobs_for_startup(...)`.
- Enforce idle-time filter in DB selection logic (not only in-memory
filtering after `scan_limit`) so eligible threads are not starved by
very recent threads.
- Enforce global running cap of 64 at claim time in DB logic:
- Count fresh `memory_stage1` running jobs.
- Only allow new claims while count < cap.
- Keep stale-lease takeover behavior intact.
- Add/adjust tests in `state/src/runtime.rs`:
- Idle filter inclusion/exclusion around 12h boundary.
- Global running-cap guarantee.
- Existing stale/fresh ownership behavior still passes.
Acceptance criteria:
- Startup never creates more than 64 fresh `memory_stage1` running jobs.
- Threads updated <12h ago are skipped.
- Threads older than 30d are skipped.
## PR 2: Stage-1 output contract + storage artifacts
(forward-compatible)
- Update parser/types to accept the new structured output while keeping
backward compatibility:
- Add `rollout_slug` (optional for now).
- Add `rollout_summary`.
- Keep alias support for legacy `summary` and `rawMemory` until prompt
swap completes.
- Update stage-1 schema generator in `core/src/memories/stage_one.rs` to
include the new keys.
- Update prompt templates:
- `core/templates/memories/stage_one_system.md`.
- `core/templates/memories/stage_one_input.md`.
- Replace storage model in `core/src/memories/storage.rs`:
- Introduce `rollout_summaries/` directory writer (`<thread_id>.md`
files).
- Introduce `raw_memories.md` aggregator writer from DB rows.
- Keep deterministic rebuild behavior from DB outputs so files can
always be regenerated.
- Update consolidation prompt template to reference `rollout_summaries/`
+ `raw_memories.md` inputs.
Acceptance criteria:
- Stage-1 accepts both old and new output keys during migration.
- Phase-1 artifacts are generated in new format from DB state.
- No dependence on per-thread files in `raw_memories/`.
## PR 3: Remove per-cwd memories and move to one global memory root
- Simplify layout in `core/src/memories/layout.rs`:
- Single root: `codex_home/memories`.
- Remove cwd-hash bucket helpers and normalization logic used only for
memory pathing.
- Remove scope branching from startup phase-2 dispatch path:
- No cwd/user mapping in `core/src/memories/startup/mod.rs`.
- One target root for consolidation.
- In `state/src/runtime/memory.rs`, stop enqueueing/handling cwd
consolidation scope.
- Keep one logical consolidation scope/job key (global/user) to avoid a
risky schema rewrite in same PR.
- Add one-time migration helper (core side) to preserve current shared
memory output:
- If `~/.codex/memories/user/memory` exists and new root is empty,
move/copy contents into `~/.codex/memories`.
- Leave old hashed cwd buckets untouched for now (safe/no-destructive
migration).
Acceptance criteria:
- New runs only read/write `~/.codex/memories`.
- No new cwd-scoped consolidation jobs are enqueued.
- Existing user-shared memory content is preserved.
## PR 4: Phase-2 global lock simplification and cleanup
- Replace multi-scope dispatch with a single global consolidation claim
path:
- Either reuse jobs table with one fixed key, or add a tiny dedicated
lock helper; keep 1h lease.
- Ensure at most one consolidation agent can run at once.
- Keep heartbeat + stale lock recovery semantics in
`core/src/memories/startup/watch.rs`.
- Remove dead scope code and legacy constants no longer used.
- Update tests:
- One-agent-at-a-time behavior.
- Lock expiry allows takeover after stale lease.
Acceptance criteria:
- Exactly one phase-2 consolidation agent can be active cluster-wide
(per local DB).
- Stale lock recovers automatically.
## PR 5: Final cleanup and docs
- Remove legacy artifacts and references:
- `raw_memories/` and `memory_summary.md` assumptions from
prompts/comments/tests.
- Scope constants for cwd memory pathing in core/state if fully unused.
- Update docs under `docs/` for memory workflow and directory layout.
- Add a brief operator note for rollout: compatibility window for old
stage-1 JSON keys and when to remove aliases.
Acceptance criteria:
- Code and docs reflect only the simplified global workflow.
- No stale references to per-cwd memory buckets.
## Notes on sequencing
- PR 1 is safest first because it improves correctness without changing
external artifact layout.
- PR 2 keeps parser compatibility so prompt deployment can happen
independently.
- PR 3 and PR 4 split filesystem/scope simplification from locking
simplification to reduce blast radius.
- PR 5 is intentionally cleanup-only.

## Align with the new phase-1 design
Basically we know run phase 1 in parallel by considering:
* Max 64 rollouts
* Max 1 month old
