• Add five recovery routes while keeping request state in the upstream private API.
• Gate recovery on Turnstile, Hive owner history, and server-verified ownership proof.
• Test recovery rules and handlers, and document expected parity differences for the new routes.

High-Level Assessment
The following are alternative approaches to this PR:
1. Validate recovery inside the state-owning private API
➕ Could make validation and request-state transitions one authoritative operation.
➕ Would avoid some gateway-to-upstream round trips.
➖ Requires Hive RPC and proof-verification capabilities in the private API.
➖ Moves validation away from the existing gateway infrastructure.
Recommendation: Keep the proposed gateway validation and upstream state ownership for this additive API feature. If recovery becomes subject to concurrent state changes, consider upstream revalidation at state transitions to address the gap between checking chain state and forwarding.

Bind recovery Turnstile checks to the recover action
• Allows the shared Turnstile verifier to require a specific widget action. Existing account-creation callers retain success-only behavior.
• Adds start, prove, verify-code, status, and complete handlers. They validate input, check applicable chain and request state, verify ownership proof on prove, and forward accepted operations to the state-owning private API.

Handle pagination limits when searching recovery history
For accounts with more than 2,000 history entries and no recover_account operation among their latest 2,000 entries, this single filtered request can fail even when the account is eligible for recovery. The Hive account-history implementation limits filtered scans to 2,000 inspected operations and throws a pagination exception when no matches were found (lines 126–150). HiveRpcClient propagates RPC errors without failover, and TryReadRecoveryChain converts the exception into a 503, blocking both start and prove for affected accounts on nodes using this implementation. Handle the continuation cursor or obtain the latest recovery time without an unpaginated history scan.
IsSingleKeyAuthority checks the requested key but does not inspect account_auths before
RecoveryComplete accepts the on-chain owner authority. If that authority also delegates owner
access to another account, completion proceeds even though the requested key is not its sole means
of authorization.
2. Callers can evade recovery rate limits 🐞 Bug⛨ Security
Description
RecoveryStart sends the value returned by SignupClientIp to the upstream service as ip, but
that helper takes X-Real-IP verbatim from the request. When a caller can reach this listener
directly or through an ingress that preserves the header, rotating its value defeats the
per-client-address limit on which this route relies.
+ var payload = new JsonObject { ["username"] = username, ["ip"] = ip };+ await Upstream.Pipe(RecoveryUpstream("recovery-request/start", HttpMethod.Post, payload), ctx);
Evidence
The new handler identifies upstream per-address limiting as its protection and forwards the
header-derived value as that address. The helper does not authenticate the header, and the
application listens on all interfaces without trusted-proxy middleware.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The recovery limiter receives a client-supplied header value as the caller's address.
## Fix Focus Areas
- dotnet/EcencyApi/Handlers/PrivateApi.Recovery.cs[144-153]
- dotnet/EcencyApi/Handlers/PrivateApi.Recovery.cs[180-181]
- dotnet/EcencyApi/Handlers/PrivateApi.Accounts.cs[50-61]
## Recommended Fix
Accept a forwarded client address only from a configured trusted proxy that overwrites the header; otherwise derive the address from the connection or reject the request. Use that verified address for both captcha verification and the upstream payload.

3. Oversized proofs consume server resources✓ Resolved
Description
RecoveryProve passes an unbounded signature string to ProofMatches, whose signature decoder
converts the entire hex string before checking its required byte length. A caller with a started
request can repeatedly submit large invalid proofs under the server's 50 MB body limit, making each
attempt buffer and parse the body and allocate for hex decoding without advancing request state.
4. Bad history reads deny valid recovery✓ Resolved
Description
UsableEntries silently skips null owner-history entries and entries with an unreadable
last_valid_time rather than treating the chain answer as unreadable. If the skipped entry is the
only recent change or contains the proven key, start returns no_recent_owner_change or prove
returns key_not_recent instead of reporting a chain-read failure.
View medium (1) 5. Chain failures leave no diagnostic trail✓ Resolved
Description
TryReadRecoveryChain and the additional owner-operation read catch every exception without
recording the exception or the failing RPC. Node outages and history-parsing defects therefore
produce the same 503 response with no traceback to distinguish or diagnose them.

Summary
Recovery validation and history rules dotnet/EcencyApi/Infrastructure/RecoveryRules.cs, dotnet/EcencyApi/Infrastructure/HiveCrypto.cs, dotnet/EcencyApi.Tests/RecoveryTests.cs
Adds public-key and signature validation, recovery proof and request checks, and rules for owner authority, chain history, and recovery windows. Tests cover these rules and owner-key history.
Adds handlers and routes for recovery start, prove, verify-code, status, and complete. Handlers check request state and chain eligibility before forwarding operations. Turnstile verification supports an expected action. Tests cover handler responses and forwarding; parity cases record the recovery routes.

Merge Risk: Low · previous review 11adb
The new recovery routes are behind a feature flag and are mostly sound. Before merging, stop logging raw RPC error text and include delegated account creation when determining when a key entered the owner authority. Both are narrow, low-effort fixes with limited impact.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Reject delegated owner accounts before completing recovery.
If the owner authority has weight_threshold: 1, the new key at weight 1, and another account in account_auths at weight 1, this predicate returns true. RecoveryComplete then forwards completion although the other account still has owner authority. RecoveryHandlerTests.CompleteForwards explicitly accepts that state. Require account_auths to be empty before reporting recovery complete. Hive’s owner authority includes account_auths; changing the owner key alone need not remove those authorizations.

… inputs
- A proven key must meet the old owner threshold on its own (key_not_sufficient
at start and prove).
- The latest recovery time comes from the account's last_account_recovery field
instead of a filtered history scan.
- owner_since only counts the account's own creation, and falls back to null
when the history read fails or cannot be read.
- Completion accepts an owner of exactly the new key meeting its threshold and
no account auths.
- Unreadable owner history entries are a read failure (503), never skipped.
- Signatures, public keys, request ids and codes are length checked before any
decoding.
- Failed chain reads log the method and cause once, without account details.
…uthority
A later owner update that keeps the key no longer moves it forward. When the
history read does not reach back to where the key was added, it is unknown
(null). Only owner changes of the account itself count.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Use an indistinguishable response for account-dependent start outcomes.
After captcha, RecoveryStart returns 404 for a missing account, 422 for an ineligible account, and a forwarded 409 in_progress response for an active request. An unauthenticated caller can test a chosen username and learn whether recovery is underway. Return a generic start response; provide detailed state only through a verified channel. Based on learnings: “The endpoint should return an identical, generic response regardless of whether the email/account exists, sending succeeded, or such an error occurred.”
