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
openspec/changes/archive/2026-09-05-forms-library.
Vendor htmx 4.0.0 and complete the migration with no compat shim:
mark inherited attributes with :inherited, rename hx-disabled-elt to
hx-disable, and drop hx-disinherit. Update static scripts to the
colon-separated event names and detail.ctx shape, and move error-swap
suppression to declarative noSwap config so 422 swaps natively while
403/5xx responses leave the target unchanged.
Handlers that branch on HX-Request now declare Vary: HX-Request. Add
lint guards for htmx 2 residue: hx-disinherit, camelCase event names,
and htmx-2-compat references.
Rewrite the README around purpose, architecture, quickstart, and
status. Add contributing/security policies plus a docs index with
audience front matter across existing docs.
