YeonGyu-Kim eaa077bf91 fix: #150 — eliminate symlink canonicalization flake in resume_latest test + file #246 (reminder outcome ambiguity)
## #150 Fix: resume_latest test flake

**Problem:** `resume_latest_restores_the_most_recent_managed_session` intermittently
fails when run in the workspace suite or multiple times in sequence, but passes in
isolation.

**Root cause:** `workspace_fingerprint(path)` hashes the path string without
canonicalization. On macOS, `/tmp` is a symlink to `/private/tmp`. The test
creates a temp dir via `std::env::temp_dir().join(...)` which returns
`/var/folders/...` (non-canonical). When the subprocess spawns,
`env::current_dir()` returns the canonical path `/private/var/folders/...`.
The two fingerprints differ, so the subprocess looks in
`.claw/sessions/<hash1>` while files are in `.claw/sessions/<hash2>`.
Session discovery fails.

**Fix:** Call `fs::canonicalize(&project_dir)` after creating the directory
to ensure test and subprocess use identical path representations.

**Verification:** 5 consecutive runs of the full test suite — all pass.
Previously: 5/5 failed when run in sequence.

## #246 Filing: Reminder cron outcome ambiguity (control-loop blocker)

The `clawcode-dogfood-cycle-reminder` cron times out repeatedly with no
structured feedback on whether the nudge was delivered, skipped, or died in-flight.

**Phase 1 outcome schema** — add explicit field to cron result:
- `delivered` — nudge posted to Discord
- `timed_out_before_send` — died before posting
- `timed_out_after_send` — posted but cleanup timed out
- `skipped_due_to_active_cycle` — previous cycle active
- `aborted_gateway_draining` — daemon shutdown

Assigned to gaebal-gajae (cron/orchestration domain). Unblocks trustworthy
dogfood cycle observability.

Closes ROADMAP #150. Filed ROADMAP #246.

Claw Code

Claw Code is the public Rust implementation of the claw CLI agent harness. The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.

[!IMPORTANT] Start with USAGE.md for build, auth, CLI, session, and parity-harness workflows. Make claw doctor your first health check after building, use rust/README.md for crate-level details, read PARITY.md for the current Rust-port checkpoint, and see docs/container.md for the container-first workflow.

ACP / Zed status: claw-code does not ship an ACP/Zed daemon entrypoint yet. Run claw acp (or claw --acp) for the current status instead of guessing from source layout; claw acp serve is currently a discoverability alias only, and real ACP support remains tracked separately in ROADMAP.md.

Current repository shape

  • rust/ — canonical Rust workspace and the claw CLI binary
  • USAGE.md — task-oriented usage guide for the current product surface
  • PARITY.md — Rust-port parity status and migration notes
  • ROADMAP.md — active roadmap and cleanup backlog
  • PHILOSOPHY.md — project intent and system-design framing
  • src/ + tests/ — companion Python/reference workspace and audit helpers; not the primary runtime surface

Quick start

[!NOTE] [!WARNING] cargo install claw-code installs the wrong thing. The claw-code crate on crates.io is a deprecated stub that places claw-code-deprecated.exe — not claw. Running it only prints "claw-code has been renamed to agent-code". Do not use cargo install claw-code. Either build from source (this repo) or install the upstream binary:

cargo install agent-code   # upstream binary — installs 'agent.exe' (Windows) / 'agent' (Unix), NOT 'agent-code'

This repo (ultraworkers/claw-code) is build-from-source only — follow the steps below.

# 1. Clone and build
git clone https://github.com/ultraworkers/claw-code
cd claw-code/rust
cargo build --workspace

# 2. Set your API key (Anthropic API key — not a Claude subscription)
export ANTHROPIC_API_KEY="sk-ant-..."

# 3. Verify everything is wired correctly
./target/debug/claw doctor

# 4. Run a prompt
./target/debug/claw prompt "say hello"

[!NOTE] Windows (PowerShell): the binary is claw.exe, not claw. Use .\target\debug\claw.exe or run cargo run -- prompt "say hello" to skip the path lookup.

Windows setup

PowerShell is a supported Windows path. Use whichever shell works for you. The common onboarding issues on Windows are:

  1. Install Rust first — download from https://rustup.rs/ and run the installer. Close and reopen your terminal when it finishes.
  2. Verify Rust is on PATH:
    cargo --version
    
    If this fails, reopen your terminal or run the PATH setup from the Rust installer output, then retry.
  3. Clone and build (works in PowerShell, Git Bash, or WSL):
    git clone https://github.com/ultraworkers/claw-code
    cd claw-code/rust
    cargo build --workspace
    
  4. Run (PowerShell — note .exe and backslash):
    $env:ANTHROPIC_API_KEY = "sk-ant-..."
    .\target\debug\claw.exe prompt "say hello"
    

Git Bash / WSL are optional alternatives, not requirements. If you prefer bash-style paths (/c/Users/you/... instead of C:\Users\you\...), Git Bash (ships with Git for Windows) works well. In Git Bash, the MINGW64 prompt is expected and normal — not a broken install.

[!NOTE] Auth: claw requires an API key (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.) — Claude subscription login is not a supported auth path.

Run the workspace test suite:

cd rust
cargo test --workspace
