fix(dashpay): accept HASH160 profile authentication keys - #991
Conversation
Delegate profile create and update to the managing wallet with the existing identity signer. Validate inputs and report unsupported field clearing and wallet-less writes explicitly. Preserve profile metadata during refresh. Document upstream HASH160 limitations and add focused unit coverage plus an opt-in testnet create/replace test using a wallet-derived HIGH key.

Final validation — Phase 2 only (queue backlog)
The HASH160 policy expansion introduces a profile-saving regression for mixed-key identities: an unavailable HASH160 key can now take precedence over a usable raw ECDSA key. The duplicate signer findings are consolidated below; the withdrawal-label suggestion is excluded because the same completion-only terminology already covered expired withdrawals before this PR.

- [BLOCKING] src/wallet_backend/dashpay.rs:906-910: Skip unavailable keys when selecting the profile signing key
Adding HASH160 to this policy and the pinned upstream selector can break profile creation and updates that previously worked. For an identity with an active HIGH/CRITICAL HASH160 authentication key at a lower ID and a usable raw ECDSA authentication key at a higher ID, the old selector skipped HASH160 and selected the usable key. The new upstream `profile_signing_key` calls `get_first_public_key_matching`, which iterates the identity's BTreeMap in key-ID order without checking private-key availability. Both external-signer profile methods pass that selected key to `put_document`; `QualifiedIdentity::sign` resolves that exact key and fails when its private material is unavailable, rather than trying the higher-ID key. The local preflight only checks public-key eligibility and cannot prevent this. Although the PR description acknowledges the limitation, this particular mixed-key case is a regression introduced by the expanded selector. Make selection availability-aware in the actual upstream publication path, or provide an API that accepts the exact usable key; changing only this preflight is insufficient. Add a regression test covering both create and update with an unavailable lower-ID HASH160 key and an available higher-ID raw ECDSA key.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Failed withdrawals are still labeled as completed in the history view — Out of scope as a pre-existing terminology issue. At base 4940fd5, RecentlyCompletedWithdrawals already queried both COMPLETE and EXPIRED while displaying the same completion-only heading and empty-state message. This PR adds another terminal status and correctly renders its per-row status as failed; it does not introduce the broader mismatch between terminal-history contents and completion-only labels. Renaming that existing history section is adjacent cleanup rather than a required correction to HASH160 support or failed-status handling.
- Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.
Pin Platform to the fix in dashpay/platform#4764 so an unavailable HASH160 key cannot shadow an available ECDSA key during profile writes. Add mixed-key create/replace E2E coverage and document the dependency. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub>

Re-review — Final validation — Phase 1 + Phase 2
The profile implementation correctly delegates signer-aware key selection to the pinned upstream API, and the prior unavailable-key blocker is fixed. The new failed-withdrawal behavior is not fully reflected in the GUI/backend labels or MCP tool description, and identities with no locally signable eligible key still receive a generic write failure. No blocking issues were found.
🟡 3 suggestion(s)
3 finding(s) not shown inline (the lines are not part of this PR's diff)
🟡 Suggestion: Do not label failed withdrawals as completed
src/backend_task/platform_info.rs:826-850
The withdrawal history query now includes COMPLETE, EXPIRED, and FAILED statuses, but both the empty-state text and the rendered heading still say "recently completed withdrawals." A result containing only failed withdrawals is therefore presented as a successful completion history, even though individual rows show "failed." Use a neutral label such as "Recent Withdrawal History" and update the corresponding GUI and CLI labels as well.
source: gpt-6-astra (phase2-reviewer: rust-quality)
🟡 Suggestion: Keep the MCP withdrawal description aligned with returned statuses
src/mcp/tools/platform.rs:110-114
The completed withdrawal query now returns failed withdrawals as well as complete and expired ones, and the structured entry documentation already lists "failed." However, the tool description still tells MCP clients that completed results contain only complete or expired statuses. Update the description so clients can correctly interpret the response.
"Query withdrawal documents from Platform. \
Pass status=\"queued\" (default) for in-queue withdrawals \
(queued, pooled, or broadcasted) or status=\"completed\" for \
finished ones (complete, expired, or failed). \
Use limit and start_after for pagination."
source: gpt-6-astra (phase2-reviewer: rust-quality)
🟡 Suggestion: Preserve the specific error for identities without a locally signable profile key
src/wallet_backend/dashpay.rs:932-940
ensure_profile_signing_key verifies that the managed identity has an eligible on-chain key, but it does not check whether the supplied QualifiedIdentity signer has any eligible key placement. When an identity has an eligible public key but none of its private keys are locally available, the upstream signer-aware selector fails before signing and this path maps the result to generic ProfileWriteFailed rather than ProfileSigningKeyUnsupported. Check the supplied signer with the same eligibility policy before dispatching the profile write so the user receives the specific actionable error. This should remain a placement check; vault resolution failures can still be handled by the actual signing path.

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Vault-dead first key still blocks a live second key (no signing retry) — A stale vault placeholder can still make
can_sign_withreport a key as available even when vault resolution fails, and the profile operation does not retry a later eligible key after that signing failure. This is a concrete edge case, but the PR explicitly limits availability to stored placements and documents that actual signing failures are not retried; fixing it requires a vault-aware upstream selection or retry design.- Follow-up: Track separately as an upstream/profile signer availability issue.
…history Check eligible managed-identity keys against the supplied signer's placements before publishing, preserving the actionable error when none is available. Cover unavailable, ineligible, and mixed-key placements in profile tests. Use neutral withdrawal history labels and document failed terminal results.

TL;DR: Enable DashPay profile creation and updates with hashed ECDSA identity keys, including identities with only some private keys available.
User story
As a wallet user, I want to save my DashPay profile using an eligible identity key available in my wallet.
Scenario
A wallet-linked identity has an unavailable HIGH-security HASH160 authentication key at a lower ID and an available ECDSA authentication key at a higher ID. Profile creation and replacement skip the unavailable key and use the available key. Fully provisioned HASH160-only identities are supported too.
