A complete offline licensing layer (no internet at any step):
Core
- src/license/ — schema (License, Tier, FeatureFlag), HMAC crypto,
JSON storage, LicenseManager singleton with activate/renew/
deactivate/issue_trial. Tier-scaffolded so future SKUs can carve
per-tool feature sets without consumer-code edits.
- scripts/generate_license.py — creator-only key generator. Mints a
DTLIC1: blob the buyer pastes into the activation page.
GUI
- New activation form component (src/gui/components/activation.py).
- hide_streamlit_chrome() now inline-renders the activation form when
no valid license is present (every page short-circuits to the form
until activated).
- Sidebar shows tier + days remaining; renewal warning under 30 days.
- New pages/_Activate.py for revisiting the form after activation.
CLI
- src/license_cli.py — activate / renew / status / trial / deactivate
commands. Exempt from the guard.
- src/cli_license_guard.py — drop-in guard call added to every tool
CLI's main(). Lets --help through; respects DATATOOLS_DEV_MODE.
i18n
- New activation.* and license.* keys in en.json + es.json
(page title, form labels, status badges, renewal warnings, error
messages). Pack parity test stays green.
Test infrastructure
- tests/conftest.py autouse fixture sets DATATOOLS_DEV_MODE=1 so the
existing 1916 tests continue to pass.
- isolated_license_path / activated_license_manager /
unactivated_license_manager fixtures for tests that want to drive
the real check.
Tests (+79)
- tests/test_license.py (40): schema, crypto roundtrip, blob
encode/decode, tier→feature mapping, activation flow, name/email
mismatch rejection, tamper detection, expiration, renewal,
dev-mode bypass.
- tests/test_license_cli.py (26): every license_cli command +
subprocess tests confirming every tool CLI refuses to run without
a license, --help always works, DEV_MODE bypasses.
- tests/gui/test_activation.py (13): gate blocks without license,
passes with trial, activation form submission unlocks the gate,
sidebar status, renewal warning, i18n.
Total: 1916 → 1995 tests. All pass under the strict warning filter.
