feat: contribute-for-credits program (landing + /contribute + pricing) [early access]

[abrichr]

Coordinated early-access rollout — hold for final program approval

This is the public website surface for the data-for-credits target state. The underlying Cloud mechanism is inert and OFF by default until the versioned contribution terms, named de-identification standard and attestation, jurisdiction scope, and curation path are active. Nothing in this PR enables uploads or claims customer data has been collected.

Public surfaces

1. Landing-page section after the adoption block, framed as strengthening the shared hardening corpus.
2. Dedicated /contribute page with the local sanitize → exact-byte approval → validated ingest → credits lifecycle and the existing contact intake.
3. Pricing callout that extends the monthly run allowance rather than creating a pay-with-data tier.

Binding copy contract

• raw recordings never leave the contributor boundary
• only a locally reviewed, hash-bound derivative is eligible
• the contributor organization must attest that it meets the named de-identification standard in the versioned terms; sanitization alone is not presented as a legal determination
• contributors can stop future contributions at any time; accepted contributions remain governed by the terms version approved at submission
• service credits only, never cash or per-record pricing
• early access/request access, never available today

Verification

• npm test: 117 tests pass, including two new contribution-copy regression tests
• the page remains statically renderable
• GitHub CI is authoritative while the owning Netlify team remains quota-blocked; the Netlify failures occur before source build

Hold merge until the coordinated program copy and terms are approved together. The code path remains fail-closed and OFF by default.

Pausing this PR after launch-path review.

The current diff is a well-structured public explanation and request-access surface, but it does not ship the target-state contributor product: there is no accepted contribution agreement, contribution/approval path, credit ledger, or usage-cap application. Publishing an “Early access / there is no upload flow today” page would add a temporary waitlist-style promise to the sales surface.

The work is preserved on this branch. Resume it when the actual mechanism can land with the page: versioned terms, hash-bound approved-derivative intake, eligibility validation, auditable credit issuance, and control-plane application of credits. Until then it is intentionally outside the launch critical path.

[abrichr]

Closing for launch focus while preserving the branch and history. This surface promises earned run-cap credits before the versioned terms, corpus-specific destination policy and intake, eligibility rules, idempotent credit ledger, entitlement update, and actual cap application exist. It also trails current main and would fragment the live Cloud / Evaluate / Try locally funnel. Rebuild this as one coherent product, legal, billing, and evidence train after the mechanism works end to end.

[abrichr]

Reopened and finished per founder instruction, rebuilt on current main (post-#275/#301/#302 homepage IA). Addressing each objection from the launch-focus close:

1. "No accepted contribution agreement / versioned terms": the terms remain unfinalized by design, and the page now discloses that on itself. /contribute carries a dedicated "Program status and eligibility" section stating the contribution path is versioned-terms-gated and off by default until a finalized terms version is active, that acceptance records the exact terms version and timestamp, and that no customer or patient data has been collected through this program. The promise-before-terms objection is converted into disclosed status, which is the early-access pattern the binding framing brief prescribes.

2. "No contribution/approval path, credit ledger, or usage-cap application": the mechanism exists and is merged in openadapt-cloud feat(stats): add PyPI download statistics visualization #103 (consent record, idempotent credit ledger, contribution rows over already-approved hash-bound sanitized derivatives). It ships inert and unreachable until an operator sets CONTRIBUTION_CREDITS_ENABLED plus a real CONTRIBUTION_TERMS_VERSION. The page never claims a live upload flow; copy is request-access only.

3. "Temporary waitlist-style promise on the sales surface": intake is no longer a generic contact reuse. A dedicated Netlify form (contributor-program) is registered in public/form.html and posted over the durable /form.html lead path, so contributor leads are segmented and durable, same pattern as workflow-qualification.

4. "Trails current main / would fragment the live funnel": rebuilt on current origin/main. The landing section is re-homed after TrustSummary (trust/open-source cluster) and stays out of the hero, the commercial offer, and the closing qualification CTA. The pricing callout is re-applied to the current Pricing component as the chosen Option A callout. Stale /#pricing anchor fixed to /pricing.

Regression tests (tests/contributeProgram.test.js) lock the framing contract: no sell/monetize-your-data language, no per-record price, early-access-only status, runtime/Netlify form-name parity, and no em dashes. Full npm run build (prebuild tests, 138 pass) is green locally.
