Why

Every agent worktree shares one cargo build dir (build.build-dir), and it reached 89-130 GB within a day or two. On 2026-10-06 it held 89 GB: 77 GB debug/deps and 12 GB debug/incremental.

Change

• [profile.dev] debug = "line-tables-only": backtraces keep file and line.
• [profile.dev.package."*"] debug = false: dependencies carry no debuginfo.
• runner/README.md documents CARGO_PROFILE_DEV_DEBUG=full for debugger sessions.

The test profile inherits both. The release profile is unchanged. CI sets CARGO_PROFILE_{DEV,TEST}_DEBUG=0 in rust-test.yml and rust-coverage.yml, and that env still overrides the manifest, so CI and coverage builds stay the same.

Measurements

These are from a clean cargo build --workspace --exclude zone_desktop --all-targets with default features, followed by three edits to zone_server/src/lib.rs. Each run used its own isolated build dir on an M-series Mac with 16 cores. Other sessions were loading the machine, so timings are ±3 s.

	clean build	size, clean → after 3 edits	edit-rebuild
full debuginfo (main)	155 s	32 GB → 36 GB	33–36 s
this PR	123 s	25 GB → 29 GB	32–36 s
this PR + incremental off (cargo test --no-run)	106 s	19 GB → 20 GB	66–70 s

Incremental stays on, because turning it off doubled the edit-rebuild time. A machine-local hourly prune now ages out stale incremental caches and per-worktree artifacts instead.

What still fills deps: 137 test executables take 14.8 of its 19 GiB, at about 110–250 MB each. Each one statically links zone_server and ONNX Runtime, and this profile change can't shrink that. Merging zone_server's 100 integration test files into a single test binary is the next lever, and it belongs in its own PR.

I checked that a panic under this profile on macOS still prints at ./src/main.rs:1:14 frames.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Login status now checks for an in-progress sign-in before refreshing login usage, helping status updates reflect sign-ins that are still underway.
• Development
  • Development and test builds now retain line-level debugging information for project code while omitting it for dependencies, keeping builds lighter.
  • Developers can build the server with full debugging information for project code when needed.
• Documentation
  • Setup instructions now explain the debugging information included in development and test builds and how to enable full project debugging information.

Walkthrough

The development profile now retains line-table debug information and disables debug information for dependencies. Login status reads check pending sign-in state before listing logins. Integration tests share a refused-connection URL, and the chat routing branch binds its route locally.

Changes

Development Debug Information

Layer / File(s)	Summary
Development profile and build guidance runner/Cargo.toml, runner/README.md	The development profile retains line-table debug information and disables dependency debug information. The README describes these settings and gives a command to build zone_server with full workspace debug information.

Login Status Read Ordering

Layer / File(s)	Summary
Pending sign-in status ordering runner/zone_server/src/services/login/status.rs, runner/zone_server/tests/integration/agent_login.rs	AgentStatus::read captures pending sign-in state before listing logins and refreshing usage. An integration test delays usage responses while a second Codex sign-in is approved and status is read.

Refused Connection Test Endpoints

Layer / File(s)	Summary
Shared refused-connection URL and test use runner/zone_server/tests/integration/common/mod.rs, runner/zone_server/tests/integration/chat_ws.rs, runner/zone_server/tests/integration/lora_flows.rs	The integration tests use the shared REFUSED_URL for unreachable services. A test checks that the URL refuses a connection within five seconds and uses a port below 1024. The training-bases test continues to check base listings while Ollama is unreachable.

Chat Route Local Binding

Layer / File(s)	Summary
Chat route binding runner/zone_server/src/ws/chat.rs	The Routing::Chat branch binds the boxed route to a local Route value. Routing behavior is unchanged.

As written, the chat routing change prevents zone_server from building, which blocks every build, test and deployment of the server. Changing *route to route in the prepare_chat call is a one-line fix. The build-size and login-status changes otherwise look ready to merge.

route = *route already binds an unboxed Route. Remove the extra dereference at
