Derive Stripe test/live mode from the API key prefix at boot, failing on
unrecognized prefixes, and drop the separate `stripe-mode` config key.
Refine disabled controls to render through the shared `disabledControl`
part with the not-allowed cursor, and add a lint rule refusing
hand-rolled disabled buttons.
Adjust plan cards to offer no purchase control on free rungs, fix bound
checkbox Bool handling, and rename "Public/Private" to "Listed/Unlisted"
with enhanced readiness verdicts.
Introduce a commercial license option alongside AGPL-3.0-only, require a
CLA for contributors, and document the terms in COMMERCIAL.md and
NOTICE. Add a script to stamp SPDX headers on Go files and apply it
across the tree.
Width becomes a one-rung step from the control's natural fraction,
and invariants bound the ladder. The grant's free text is renamed
to GrantNote, and both grant ledgers show it as a muted note line.
Every form on both surfaces is now a declared FormSpec in
internal/forms, rendered through the shared form part and parsed
by its handler through the same declaration. Create and edit
share one field list, refusals answer 422 with values carried
back, and layout, buttons and errors come from one part.
Also adds the form registry with its invariant and route-mapping
tests, the raw-form, filler-copy and Go em-dash lint rules,
declared action triggers, and the capture-coverage cross-check.
The forms-library change is archived under
