The Keysat client's payload exposes both:
• licenseId — raw 16-byte UUID as Uint8Array
• licenseUuid — same value, canonical string form
server/license.js was sending licenseId (the Uint8Array). After JSON
serialization that turned into an object like {"0":1,"1":2,...} on
the wire. The frontend's renderLicenseBlock() calls
`lic.licenseId.slice(0, 8)` to abbreviate the ID for display — .slice
doesn't exist on that object, so the template threw, the
app.innerHTML assignment silently aborted, and clicking the gear
looked like a no-op.
The render error guard added in 0.1.17 caught it on first repro:
Render error: lic.licenseId.slice is not a function
Fix: switch to payload.licenseUuid (the string form).
Without this, a license revoked in the Keysat admin UI keeps unlocking
the app on the customer's machine — Ed25519 signatures are perpetually
valid, so the offline-only check never sees the revocation.
What this adds:
• license.js: validateOnline() calls licensing.keysat.xyz/v1/validate
via @keysat/licensing-client's Client. Hard rejections (revoked,
suspended, expired, not_found, product_mismatch, fingerprint_mismatch,
too_many_machines, invalid_state) immediately flip state to "invalid"
and persist the verdict to <license>.state.json so it survives
restarts. rate_limited and unknown reasons are treated as transient.
• Network errors keep the prior state for up to MAX_OFFLINE_DAYS
(default 7, env-overridable) since the last successful validate.
Past the ceiling, lock out with reason=validation_overdue. This
avoids breaking customers when Keysat is briefly down while still
catching revocations on machines that go offline forever.
• license.js: deactivate() helper that removes both license.txt and
its sidecar state file (idempotent). publicView() now exposes
lastValidatedAt, serverStatus, graceUntil for the UI.
• index.js: refreshLicenseOnline() runs on startup (async, non-
blocking), every 6h thereafter (env-overridable), and at activation
time with an 8s timeout cap so a slow Keysat doesn't hang the
activation UI. State changes are logged.
• index.js: /api/license/activate now awaits an online confirmation
after the offline signature check passes. A revoked key pasted into
the activation modal fails fast instead of working until the next
poll.
Snapshot of the working tree before cleanup. Captures:
- Keysat licensing: server/license.js, /api/license/* endpoints in
server/index.js, activation modal in public/index.html, embedded
Ed25519 issuer key (assets/issuer.pub).
- StartOS 0.4 expansion: setApiKey action, version files v0.1.1
through v0.1.15, file-models/config.json.ts, manifest updates.
- Self-hosted registry server (startos-registry/).
- Build/deploy scripts (bin/bump-version.sh, bin/deploy.sh, vendored
yt-dlp binary), .gitignore, .deploy.env.example.
- Recent design docs (KEYSAT_INTEGRATION.md, UPGRADE-DESIGN.md) —
retained here so they remain recoverable when removed in the
follow-up cleanup commit.
