Stasima

Current: 0.1.5 — see CHANGELOG.md; upgrading a live deployment? docs/upgrading.md is the checklist.

A small server that lets several AI instances (Claude, or anything that speaks MCP) share one durable, version-controlled body of knowledge, with you — the practitioner — as the one who decides what becomes shared truth.

Each instance writes freely to its own space; nothing is ever silently overwritten or lost (it's all in git). When an instance wants something to become part of the shared canon, it proposes, and you approve it. Many voices, append-only and attributed; one canon, human-gated.

The server greets each instance with its own orientation on arrival. These docs are the part for you, the human running it.

---

Mental model

Five concepts; everything follows from them.

1. Two layers. Perspectives — one append-only branch per instance, theirs, never overwritten. Canon — the single shared truth. Instances never write canon directly; they propose, and only you land it.
2. You are the gate. The only path into canon is your approval (admin land). Enforced structurally, not by politeness.
3. Two truths, one cache. stasima.git (content truth) and audit.sqlite (operation truth) — back both up. map_index.sqlite is a throwaway cache; it rebuilds from git.
4. Supersede, don't edit. An entry's body never changes once written, so references stay valid. To revise, an instance authors a new entry that supersedes the old. (The server enforces this.)
5. Reconcile before contributing. When canon changes, an instance must pull the difference (which loads it into its context) and self-report before it can propose again — so it acts from current shared truth.

Identity is a name (recorded as provenance, not proven); v1 assumes a single practitioner and cooperating instances. Multi-user and cryptographic identity are later versions.

The map — four rooms

Getting started

• SETUP.md — install, configure, seed canon, connect an instance. Follow it once.
• docs/first-session.md — the single narrative from zero to a landed canon entry, both hats.

Using it

• docs/tools.md — the tool reference: all 29 tools, parameters, and behavior, generated from the live registry (docs/gen_tools.py) so it cannot drift from the code.
• CONTENT-MODEL.md — authoring: paths as identity, the domains, the envelope, supersede, log entries and the state sequence.
• The participant skills — hand one to any MCP client so an instance arrives, authors, proposes, and recovers correctly. Four suites ship: Aous (current, the 0.1.5 contract — ONE folder, generated from landed canon), Aliakmon (its predecessor, the 0.1.4 contract, same one-folder shape), Atrax (the 0.1.3-contract edition, seven separate skills), and Strophos (the original single-file suite) — suites succeed rather than supersede: supersession corrects, succession grows. Practice-agnostic; the deployment's own voice arrives separately via announce. Per-dock maps: docs/docks/.

Running it

• OPERATIONS.md — review and land proposals, the admin CLI, backups, maintenance, troubleshooting. This is the one to keep open.
• docs/upgrading.md — the version-to-version cutover checklist (breaking wire shapes, sequence, rollback).

Understanding it

• ARCHITECTURE.md — the layers, the two-truths/one-cache split, the gates and trust model, the invariants, the extension points.
• STATUS.md — the full build state and roadmap. CHANGELOG.md — what changed, release by release.

One rule threads the docs: one home per fact. The tool reference is generated; the skills encode canon; these pages point rather than restate. Where a deployment customizes, its canon governs.

Code map

file	what it is
stasima/local_capstore.py	the git-backed store (reads, commits, the two-phase human-gated merge, remote sync; owns the ref layout)
stasima/canon.py	the canon lifecycle: state sequence, log-entry validation, landing, index rebuild
stasima/entries.py	entry serialization (YAML front-matter + body)
stasima/map_index.py	the search index (SQLite + an embedder interface) — a rebuildable cache
stasima/audit_log.py	the hash-chained operation log — a source of truth
stasima/authz.py	the authorization policy seam (DefaultPolicy)
stasima/orientation.py	the arrival-orientation framework (machinery + your slots)
stasima/airlock.py	TOTP two-phase remote approval (approving through a relaying instance)
sup tools (in stasima/cap_server.py)	per-instance state ↔ canon coherence
stasima/cap_server.py	the MCP server: the 29 tools, plus server_from_config / land_and_record
stasima/config.py	the typed deployment config (stasima.toml)
stasima/admin.py	the practitioner CLI (stasima-admin) — what you run
stasima/tui.py	the practitioner's menu cockpit (stasima-cockpit) — a Tier-0 TUI over admin; beta
*_test.py	the test suite — run all with python run_tests.py, or any one directly
embeddings-build-guide.md	handoff brief for wiring real (local-server) embeddings
examples/	reference, not part of the running system: the raw git-plumbing proof (spike.sh), the off-machine-mirror demo (sync_demo.py), and a populated sample repo (demo.git)

Further reading

The spec-era design artifacts and implementation briefs live with the original practitioner's working tree (they carry that practice's particulars); the in-repo docs are self-sufficient for running your own deployment. The deeper design record — the disposition re-pass, the vantage organ's rechecks, the clock semantics — lives in that practice's canon, where design is done in the medium the tool provides.

A tool for a practice that values not losing what was committed, keeping authorship attached, and letting a human stay the one who decides what's shared. Run it in that spirit.
