Summary

Closes #2. EVM and Terra Classic sign pages now show the full latest terms text before wallet interaction, with a consistent checkbox consent gate.

• Shared web/src/signShell.ts used by /sign/evm and /sign/terra-classic
• On load: fetch getTermsLatest + getTermsContent once; show version + effective date + scrollable body
• Consent gate: Connect & sign disabled until terms load successfully and the user checks I have read and agree to the Terms & Conditions
• Terms rendered via text nodes only (no innerHTML)
• Clear loading / error states; polite aria-live status region
• After wallet connect, if signed_latest already, show success without re-signing
• Docs/invariants: README, skills/portal-sign-disclosure/SKILL.md, gap analysis crosslinks
• Pin broken ox pkg.pr.new lockfile entry via npm override so installs resolve

Out of scope (per issue): Solana / Telegram sign pages, bot copy, redesign/i18n/multi-wallet.

Consent gate (for reviewers)

Checkbox only (not scroll-to-bottom). CTA stays disabled until:

1. Terms metadata + full text load successfully, and
2. User checks the consent checkbox.

UI gate is notice/consent UX, not auth — server still requires a valid wallet signature.

Test plan

• Unit: web/src/signShell.test.ts (XSS-as-text, consent enable, load error)
• Unit suite: npm run test:web (11 passed)
• E2E: cd web && npm run test:e2e (12 passed, retested)
• Manual: /sign/evm?property=cl8y.com and /sign/terra-classic?property=cl8y.com show current terms after sync
• Manual: CTA disabled until checkbox; then mock/real wallet sign works
• Manual: long terms scrollable at mobile width
• Confirm Solana/Telegram pages unchanged

Acceptance criteria checklist

• EVM + Terra Classic display full latest terms before wallet interaction
• Version label + effective date visible near terms
• Terms rendered safely (no HTML injection)
• User cannot start Connect & sign without consent gate (documented above)
• Loading and error states for terms fetch are clear
• EVM e2e passes; sign-page e2e asserts terms visibility + gate
• Solana/Telegram not required (postponed)

## Summary Closes #2. EVM and Terra Classic sign pages now show the **full latest terms text** before wallet interaction, with a consistent **checkbox consent gate**. - Shared `web/src/signShell.ts` used by `/sign/evm` and `/sign/terra-classic` - On load: fetch `getTermsLatest` + `getTermsContent` once; show version + effective date + scrollable body - **Consent gate:** Connect & sign disabled until terms load successfully **and** the user checks *I have read and agree to the Terms & Conditions* - Terms rendered via text nodes only (no `innerHTML`) - Clear loading / error states; polite `aria-live` status region - After wallet connect, if `signed_latest` already, show success without re-signing - Docs/invariants: README, `skills/portal-sign-disclosure/SKILL.md`, gap analysis crosslinks - Pin broken `ox` pkg.pr.new lockfile entry via npm override so installs resolve **Out of scope (per issue):** Solana / Telegram sign pages, bot copy, redesign/i18n/multi-wallet. ## Consent gate (for reviewers) Checkbox only (not scroll-to-bottom).

Review summary

Thorough review of !20 against GitLab #2 (acceptance criteria, attack/abuse table, verification checklist), the MR diff (d2e4e74), local npm run test:web (11/11), security audit of changed code, and gap analysis across packages. Issue #2 scope is satisfied. No new medium+ security issues in the diff. Residual repo risks are pre-existing / out of scope for this MR.

Closes checklist vs #2:

Acceptance criterion	Verdict
EVM + Terra show full latest terms before wallet interaction	Met (web/src/signShell.ts + page wiring)
Version + effective date visible	Met
Safe render (no HTML injection)	Met (textContent / el; unit covers XSS-as-text)
Consent gate blocks Connect & sign	Met (checkbox-only; documented in MR)
Clear loading / error states	Met (role="alert" on load failure)
EVM e2e + sign-page terms assertions	Met (web/e2e/evm-sign.spec.ts, web/e2e/sign-pages.spec.ts)
Solana / Telegram not required	Met (explicitly postponed)

Nice-to-haves from #2: already-signed short-circuit after wallet connect is implemented for EVM/Terra; manual verification items on the MR remain unchecked.

---

Security audit (MR delta)

No new medium/high/critical findings in changed code.

Area	Result
XSS / HTML injection from terms API	Mitigated — termsBody.textContent = content; unit asserts <script> stays text (signShell.test.ts)
Query property / app_name injection	Mitigated — rendered via text nodes
Consent-gate bypass (DevTools / direct API)	Expected — UI gate is notice/consent UX; server still requires valid wallet signature
Access control / privileges	No new privileged endpoints; uses existing public terms APIs
Database leaks	Not touched by this MR
Rust API / bot	Untouched
Prompt injection in skills/docs	Docs-only; skill correctly states checkbox ≠ auth
Open redirect_uri	Pre-existing (web/src/ui.ts); not weakened
CSP / clickjacking	Pre-existing; no new sinks

Attack classes (requested coverage)

Class	Applicability
Common DeFi attacks (reentrancy, flash loan, sandwich, etc.)	N/A — no contracts / no on-chain settlement
Common smart-contract attacks	N/A — none in repo
Oracle manipulation / tokenomic / economic attacks	N/A — off-chain clickwrap only
Gas optimizations	N/A — no on-chain gas surface
Database leak vectors	N/A for this MR — no schema/query changes
Common web attacks on portal	Covered above; XSS mitigated; redirect residual pre-existing

Pre-existing critical paths (do not block #2; still relevant ops risk)

Documented in gaps/GAP_1786322222.md and not introduced by this MR:

1. Telegram WebApp HMAC incorrect
2. Solana verify envelope ≠ portal signMessage
3. Terra Classic Keplr ADR-036 / signArbitrary mismatch (disclosure UX now works; end-to-end Terra sign remains broken)

---

Gap analysis (MR-scoped)

Features / UX

• Closed by !20: on-page full terms + version/date + checkbox consent for /sign/evm and /sign/terra-classic; shared renderSignShell; fetch-once; a11y live region + labeled terms region; scrollable body CSS.
• Still open (out of scope per #2): Solana/Telegram disclosure; scroll-to-bottom proof-of-read (checkbox only — allowed by issue); home hub still metadata-only; no download/print; content_sha256 not shown; mobile wallet extensions still weak.

Testing

• Present (good): unit XSS + consent + load error; e2e terms visibility + gate on EVM/Terra; e2e EVM mock-wallet accept after consent. Local web unit 11/11 green.
• Gaps (nice-to-have, not blockers): e2e terms API failure; e2e home→sign navigation; e2e malicious property; e2e already-signed short-circuit; mobile viewport long-terms; Terra full-stack wallet e2e (blocked by pre-existing Terra verify bug).

Packages

Package	MR impact
web/	Primary implementation
packages/cl8y-clickwrap/	README cross-link only
api/, bot/	Untouched
Root	ox override (supply-chain fix for broken pkg.pr.new pin), gap analysis, skill

DRY / readability / best practices

• Good extraction of shared shell; invariants documented in signShell.ts + skills/portal-sign-disclosure/SKILL.md.
• Minor a11y inconsistency: wallet onSign errors set className="error" but not role="alert" (load failures do).

CI

• MR pipeline (2745891423) passed but only ran lint:gitleaks (other jobs lack merge_request_event rules in .gitlab-ci.yml).
• Branch push pipeline failed lint:rust / lint:rust-bot on pre-existing rustfmt (no Rust changes in this MR); web/e2e jobs skipped due to stage failure.
• Recommend fixing CI rules / rustfmt on main separately so web tests actually gate MRs — not a reason to reject !20’s web change.

---

Verdict

ACCEPT for merge against #2. Implementation matches acceptance criteria, safe rendering is tested, consent gate is documented, and no security regressions were introduced. Follow-ups (Solana/Telegram disclosure, open-redirect allowlist, Terra/Solana/Telegram verify fixes, CI job rules) belong in separate issues/MRs.
