I2965 — The site says a test proves a guarantee only as far as recorded evidence supports it

✓DONE wave 0 · p0 · implementation profile · parallel safe

Part of development-runtime — The runtime has a development surface.

Objective

Qualify every site sentence that says a test proves a guarantee, or that work ends proven, to what the recorded evidence supports, and declare the proof words as homepage promises so the existing homepage check refuses them in the hand-written copy unless a supported claim permits them.

Why

Truth sweep 2026-10-18 (f6, S9 and S20, verified): the guarantees index (scripts/generate-site-data:1919) said 'What Majordomus actually does today, row by row, with the file that implements it and the test that proves it', docs/SITE_CLAIMS.md (generate-site-data:2370) 'the test that proves it', site/data/challenge.toml:28 'the test that proves the guarantee', and the homepage section title (site/data/marketing.toml:34) 'From first prompt to proven done', while site/data/registry/product.json records evidence declared 229, supported 0. homepage.toml [promises] holds capability words to supported claims and did not name the proof words.

Current state

Corrected in this change: the guarantees index and SITE_CLAIMS say the test that is to prove a claim and what its recorded run says; the challenge page says the test meant to prove it; the homepage title is 'From first prompt to a checked finish'; [promises] declares proven and proves; the claim evidence-navigates-both-ways names the test meant to settle it rather than the test that proves it.

Desired state

No site sentence says a test proves a claim while the evidence supports fewer claims than are declared, and case 3366 refuses one; the homepage check refuses proven or proves in the hand-written copy until a guaranteed, supported claim permits it.

Scope

• scripts/generate-site-data
• site/data/challenge.toml
• site/data/marketing.toml
• site/data/homepage.toml
• docs/CLAIMS.yaml
• docs/claims/evidence-navigates-both-ways.md
• test/cases/3366_a_proof_word_is_earned.sh

Dependencies

None. This issue is a root of the graph.

What waits on this

• I3122○READY A coverage figure on every surface names its dimension, its commit and what it does not measure

Acceptance criteria

• The guarantees index, SITE_CLAIMS and the site's data say a test is to prove a claim while not every claim is supported
• homepage.toml [promises] declares proven and proves, and the homepage copy uses neither

Validation

• majordomus plan validate

Those three fields, the evidence above and the state of the dependencies are all the status is made of. There is no status field to disagree with them.
