AGENTS.md — Keysat workspace

Self-hosted, Bitcoin-native software licensing service running as a StartOS 0.4.x package, with four wire-compatible SDKs and a public landing/docs site.

This file holds whole-repo, every-session facts. Subsystem detail lives in scoped guides under docs/guides/ (symlinked to .claude/rules/ so Claude Code auto-loads each when you edit matching files). Before editing a subsystem, read its guide — see the index below.

Stack

Daemon: Rust 1.88, axum, sqlx + SQLite, Ed25519 signing.
Wrapper: TypeScript, @start9labs/start-sdk ^1.3.2, @vercel/ncc bundle, Node 22.
SDKs: TS (npm), Rust (crates.io), Python (PyPI), Go (proxy.golang.org).
Platform: StartOS 0.4.0.x (LXC under the hood — commands/paths reflect that, not Docker).
Payment providers: BTCPay Server (required dep); Zaprite (optional, gated by zaprite_payments).

Note: the daemon (licensing-service-startos, repo keysat), each SDK, and plans/ are separate git repos — commit code/plan changes in their own repo. The root Licensing repo (keysat-root) tracks only AGENTS.md + docs/guides/

.claude/rules/ + EVALUATION.md (the latest full-eval report; overwritten each run, history in git log). Remotes differ per repo: the daemon's main tracks GitHub (origin, the public upstream) with a gitea backup — plain git push goes to GitHub, so also git push gitea main; root + plans are Gitea-only. Run git remote -v (full) and check what the branch tracks before pushing.

Conventions (whole-repo)

Daemon licensed LicenseRef-Keysat-1.0 (custom, source-available); SDKs MIT.
Commits in imperative mood, body only when the "why" isn't obvious. Sign as Keysat (Grant), not Claude — git user is Keysat.
Direct push to main + run ~/.keysat/publish.sh is the authorized release flow until launch.
Never rewrite user-facing copy outside the explicit scope of a request.

Never

No AI co-authorship on commits or PRs (no "Co-Authored-By", no "Generated with…").
Don't push --no-verify or bypass hooks unless explicitly authorized.
Don't commit built artifacts (*.s9pk, keysat-*.s9pk, javascript/) or secrets — reference env-var names; real values live in ~/.keysat/filebrowser.env and /data/keysat-license.txt outside the repo.

Memory references

Operator-specific memories at ~/.claude/projects/-Users-macpro-Projects-licensing-Licensing/memory/ (scan before a major change): keysat_release_workflow.md, no_unauthorized_copy_changes.md, keysat_admin_ui_pill_convention.md, startos_lxc.md, startos_registry_icon_unrenderable.md, keysat_open_threads.md.

Open TODOs

Extend publish.sh to build + upload aarch64 (arm builds fine; only x86 ships today), or narrow the manifest's arch claim. riscv target unverified.
StartOS Community Registry submission criteria — Start9 hasn't published the checklist; reach out directly when ready.
Registry icon doesn't render in the StartOS marketplace (see guides/startos-packaging.md).

Current state (2026-06-13)

Live: server immense-voyage.local runs daemon 0.2.0:54 (migrations 0020–0022 applied). Registry registry.keysat.xyz publishes :54 too (GitHub release v0.2.0-54 cut; files.keysat.xyz serves the s9pk). Four SDKs published; keysat.xyz + docs.keysat.xyz deployed.
:52/:53 = multi-provider/merchant-profile model: data model + backend resolution shipped and audited sound; the resolution/CRUD query surface now has test coverage. See docs/guides/payments.md.
Two payment-path fixes shipped 2026-06-13: (a) :53 fixed the :52 ambiguous-column bug that broke every paid purchase (daemon 31f4670); (b) :54 fixed the P0 Zaprite webhook-forgery — settle now re-confirms against the provider API before issuing (daemon 783372c, bump 495fbbf). Both built, installed to prod, and published to the registry. Live purchase + settle paths are sound.
GAP — multi-profile is non-functional end-to-end: nothing in the shipped app writes products.merchant_profile_id (the INSERT in create_product_with_currency omits it; update_product_with_currency has no field for it; the Product struct in models.rs doesn't even carry it). So every product created post-migration stays on the default profile, and a Pro operator can create extra profiles + attach providers but cannot route any product's sales to them. The data model + resolver fully support it; only the product→profile write path is missing. This is the gating piece for multi-profile — see the scoped slice below.
Triage from EVALUATION.md (full-eval, 2026-06-13) — P0/P1 = work queue, P2 = known debt, P3+ = deferred. The report at repo root has file:line evidence; it's tracked, so re-running full-eval overwrites it and git log -- EVALUATION.md preserves prior runs.
Work queue (P0/P1 — do first, in this order):
1. ✅ SHIPPED in :54 — Provider-injection test seam. Added the always-compiled AppState::provider_override + provider_from_row helper at every resolution site; greened the two paid_purchase_* tests; deleted the dead payment_provider_preference_round_trip. See docs/guides/testing.md.
2. ✅ SHIPPED in :54 — Zaprite webhook forgery fix. webhook.rs::handle_inner re-fetches provider.get_invoice_status and requires Settled before any settle-derived action; acks 200 (no issue) when the provider is unreachable. Two regression tests (forged-settle, provider-unreachable). api 47/47. Still open (auditor P1): a literal paid-amount/currency check — needs a trait change (get_invoice_status returns only a status enum). See docs/guides/payments.md. This is now the top remaining security item.
3. [P1] Scoped API keys (ks_…) are non-functional — issuable but 403 on every admin endpoint; the require_admin→require_scope migration was never done. Finish it, or stop advertising/issuing them. api/api_keys.rs:14.
- Then resume feature work: the product→merchant-profile picker (the GAP above — slice: add merchant_profile_id to the Product model + repo.rs SELECT mapping; a set_product_merchant_profile follow-up writer mirroring set_product_entitlements_catalog; the field on CreateProductReq/ UpdateProductReq applied post-write; a profile <select> from GET /v1/admin/merchant-profiles in the create+edit product forms, shown only when >1 profile; no migration), the 3 other deferred UIs (rail picker, per-profile SMTP, rail-pref editor), and unlimited_merchant_profiles on master Pro/Patron policies.
Known debt (P2 — schedule, not urgent): no rate-limit on /v1/purchase + /v1/redeem; rate-limit bucket keys on spoofable X-Forwarded-For (bypass conditional on whether the StartOS proxy rewrites XFF — unverified); 422/415 errors return plain-text not JSON (breaks SDK JSON.parse); product slug has no validation (empty/300-char/meta chars stored); GET /v1/admin/products returns 405 though OpenAPI documents it; dep advisories (sqlx→≥0.8.1 RUSTSEC-2024-0363, rustls-webpki→≥0.103.12); 4 StartOS submission blockers — missing instructions.md, dead packageRepo (…/keysat-startos→…/keysat) + docsUrls (/docs/→/licensing-service/docs/) manifest links, aarch64 declared-but-not-shipped; no CI + fmt/clippy/prettier unenforced.
Deferred (P3+ — bulk or later decision): /v1/purchase 400 vs /v1/btcpay/webhook 503 for the same no-provider cause; undocumented required kind on discount-codes; field-naming drift (license_id/id, machines key vs license_key, redeem/purchase product vs validate product_slug); migration self-heal _sqlx_migrations allowlist foot-gun; 2 KB unauth Zaprite payload WARN-log; outbound-webhook SSRF (operator-only); stale versions/v0.2.0.ts:3-4 "NOT YET WIRED" comment; re-register the master Zaprite webhook at the path-keyed URL; registry icon non-render (known platform limit); optional fmt/prettier standalone commit.
Tests/build: cargo check clean (1 intentional deprecation warning); api 43 pass / 3 known-fail (now tracked in the work queue above), other suites green. FK enforcement confirmed — sqlx pool sets foreign_keys(true) per connection (db/mod.rs). CI/fmt status is in Known debt.
