 **Pick up where you left off.**
 
-Spool is being built as a durable execution workspace for AI agents. Its goal is to keep working files, intermediate results and action history together so interrupted work can continue with an honest account of what completed and what remains uncertain.
+Spool gives local command workflows a persistent workspace and an honest record of what completed. Queue commands, keep their files and output, and inspect interrupted work before continuing.
 
-CLI and MCP are tool interfaces. Spool will provide the execution environment around them. AsDecided Core supplies versioned engineering decisions; Spool will record which decisions informed a job and surface relevant changes when it resumes.
+**v0.0.1 preview:** Linux CLI and Rust library. Explicit commands run offline through bubblewrap. This is an execution foundation, not yet a model-driven agent or MCP host. AsDecided Core integration is planned and optional.
 
-## Current status
+<img src="https://raw.githubusercontent.com/tcballard/omarchy-badges/75975e5b5bf75e7ede3764bcd2950046f7abfe2c/badges/v1/omarchy-app.svg" alt="Built for Omarchy — App" height="20">
 
-Foundation prototype, version 0.0.1 in source. No release has been published.
+Omarchy is a target platform; this badge is a community identity label. No live Omarchy version has been tested yet.
 
-Implemented: a Rust library and `spool` CLI backed by SQLite, with job creation, listing, inspection and append-only JSON checkpoints. Checkpoints survive closing and reopening the process.
+## Install on your Omarchy XPS
 
-**Not implemented yet:** tool execution, sandboxing, model integration, automatic resume, MCP adapters or AsDecided integration. A saved checkpoint is not a guarantee of safe execution recovery.
+From a checkout of this candidate (Rust 1.89+):
 
-## Try the foundation
+```bash
+sudo pacman -S --needed rust base-devel bubblewrap git
+cargo install --path . --locked
+export PATH="$HOME/.cargo/bin:$PATH"
+spool --version
+spool doctor
+```
 
-Requires Rust with edition 2024 support and a C compiler for bundled SQLite.
+`doctor` must pass before trying execution. Spool does not fall back to unsandboxed commands. Run it as your normal user, never with sudo.
+
+For a fresh checkout before publication, fetch the candidate branch:
+
+```bash
+git clone --branch feat/v0.0.1-recovery https://github.com/asdecided/spool.git
+cd spool
+```
+
+Once v0.0.1 is published, use `--branch v0.0.1` instead. Source installation avoids prebuilt glibc compatibility assumptions. CI also produces an x86_64 Linux archive and checksum for release preparation.
+
+## Try a persistent job
+
+In a new empty directory:
 
 ```bash
-cargo build --locked
-cargo install --path . --locked
 spool init
-spool new "Investigate a failing build"
-# Use the job ID returned above (1 in a fresh workspace).
-spool checkpoint 1 '{"next_step":"inspect logs","logs_saved":true}'
+spool new "XPS smoke test"
+# Use the returned job ID; these examples assume 1.
+spool queue 1 -- sh -c 'printf "hello from Spool\n" > hello.txt'
+spool queue 1 -- cat hello.txt
+spool resume 1
 spool inspect 1
-spool status
+# Completed operations are skipped; this does not run them again.
+spool resume 1
 ```
 
-State lives in `.spool/journal.sqlite3` under the current directory. Run commands from the same directory. This prototype stores checkpoint data in plaintext; keep credentials out of checkpoints. The journal is local metadata, not an isolated job workspace yet.
+Files remain in `.spool/workspaces/1/`, mounted as `/work` in the sandbox. Your repository, home directory, credentials and journal are not mounted. System tools under `/usr` are read-only. Each command has a fresh temporary directory and environment; files in `/work` persist. Host networking is unavailable.
+
+## Recovery and limits
+
+- `spool exec 1 -- command args...` queues a command and runs pending work in order.
+- `spool checkpoint 1 '{"next":"review"}'` retains explicit JSON state.
+- `spool recover` marks interrupted dispatched operations **uncertain**. It never replays them.
+- `spool resolve OP_ID succeeded 'evidence from inspecting the workspace'` records a manual conclusion. Use `failed` if the operation did not complete successfully. Do not guess.
+- `spool events OP_ID` shows the operation history.
+- Failed or uncertain operations block that job. After a failure, use a new job with a corrected command; no automatic retries are performed.
+- `spool status` lists jobs; `spool inspect JOB_ID` shows checkpoints, operations and output.
+
+Only one process can own a journal, including readers. While a command runs, other commands against that journal report busy. Ctrl+C or terminating Spool leaves dispatched work for recovery. Bubblewrap is configured to die with its parent; inspect the workspace and ensure work has stopped before resolving uncertainty.
+
+Default timeout is 60 seconds. Set `SPOOL_TIMEOUT_SECONDS` to 1–3600. A timeout is uncertain because a command may have partially written files. Captured stdout and stderr are each capped at 64 KiB and excess bytes drained; truncation is reported. Workspace disk use, memory use and process count are **not quota-limited** in this preview. Use trusted commands and disposable workspaces, not hostile workloads.
 
-## Direction
+Journal/checkpoint/output data is plaintext. Do not place secrets in command arguments or checkpoints. Persisted files and external effects are not rolled back. This preview does not claim exactly-once execution or power-loss recovery of arbitrary files. Do not delete the journal lock file while Spool is running.
 
-See [architecture](docs/architecture.md), [milestones](docs/roadmap.md) and [contributor guidance](AGENTS.md).
+## Build and test
 
 ```bash
 cargo fmt --check
 cargo clippy --all-targets --locked -- -D warnings
 cargo test --locked
+# Requires working Linux user/network namespaces and bubblewrap:
+cargo test --locked --test sandbox -- --ignored

+
+## Uninstall and data
+
+`cargo uninstall asdecided-spool` removes a Cargo-installed executable. A manually installed archive binary can be removed from `~/.local/bin/spool`. Neither removes job data. Keep `.spool/` to preserve your work; copy it only while no Spool command is running. Schema 1 reads and migrates the initial unversioned journal. Older binaries must not be used after migration.
