You are performing a code quality review on freshly committed files in the dragonrelay project (Forgejo, owner: zgaetano, repo: dragonrelay). These are Tasks 5-11 of the redesign plan — auth middleware and API handlers.

Read the following files using forgejo_get_file:

1. backend/internal/auth/host_access.go
2. backend/internal/auth/host_access_test.go
3. backend/internal/api/setup.go
4. backend/internal/api/invites.go
5. backend/internal/api/access.go
6. backend/internal/api/account.go
7. backend/internal/api/api.go (the part with checkHostAccess and getHosts filtering — this was rewritten)
8. backend/internal/api/admin.go (recent backward-compat shim added)
9. backend/cmd/dragonrelay/main.go (added a 5s-delayed backfill goroutine)

Spec context:
- The spec is at docs/superpowers/specs/2026-05-05-dragonrelay-redesign-design.md if you need to cross-check
- Per-host ACL has 3 levels: view (1) < connect (2) < manage (3); admin role bypasses; viewer role caps at view
- Public routes: GET /api/setup/state, POST /api/setup, GET /api/invite/:token, POST /api/invite/:token/redeem
- Authenticated: /api/hosts is filtered by ACL for non-admins
- Connect needs "connect" level; pair/delete need "manage" level
- Setup wizard rejected if users table non-empty
- Invite peek must NOT leak host IPs

Review for:
1. Correctness: do handlers match the spec? Status codes, request/response shapes, side effects
2. Security: any 403 paths that should be 401? Any auth bypasses? Username/password flow leaks?
3. Race conditions: especially in /api/setup which has a TOCTOU window (check empty → create user)
4. Error handling: are nil checks consistent? Are db errors propagated?
5. The backfill goroutine in main.go — does it handle ctx cancel correctly? Is the 5s delay configurable?
6. Are there any obvious bugs that would be caught immediately by `go build` or `go vet`?

Be specific (file + function name). Severity HIGH/MEDIUM/LOW. Return: ISSUES, GOOD THINGS, RECOMMENDATIONS. Keep under 1500 words.


I'll load the forgejo tool schema and read all the files in parallel.


ToolSearch

Question: select:mcp__claude_ai_mcp-server__forgejo_forgejo_get_file


I'll fetch all 9 files in parallel.


Error: Permission to use mcp__claude_ai_mcp-server__forgejo_forgejo_get_file has been denied. IMPORTANT: You *may* attempt to accomplish this action using other tools that might naturally be used to accomplish this goal, e.g. using head instead of cat. But you *should not* attempt to work around this denial in malicious ways, e.g. do not use your ability to run tests to execute non-test actions. You should only try to work around this restriction in reasonable ways that do not attempt to bypass the intent behind this denial. If you believe this capability is essential to complete the user's request, STOP and explain to the user what you were trying to do and why you need this permission. Let the user decide how to proceed.


The Forgejo file-read tool is blocked. Let me check if the dragonrelay repo is available locally instead.


Bash

find / -type d -name "dragonrelay" 2>/dev/null | head -20

Locate dragonrelay repo on filesystem

Both Bash and `forgejo_get_file` are denied, so I cannot read the source files needed for the review. Let me try the alternate Forgejo listing tool to see if anything else is accessible.

Question: select:mcp__claude_ai_mcp-server__forgejo_forgejo_list_directory,mcp__claude_ai_mcp-server__forgejo_forgejo_get_repository


I cannot complete the requested code review.

**Blocker:** Permission to use `mcp__claude_ai_mcp-server__forgejo_forgejo_get_file` was denied for all 9 file requests, and `Bash` (which I would have used to locate or read the files locally) was also denied. Without being able to read the actual contents of `host_access.go`, `setup.go`, `invites.go`, `access.go`, `account.go`, `api.go`, `admin.go`, `host_access_test.go`, or `main.go`, I have no source to review.

**What I will not do:** Fabricate findings. A code review based on guessed contents would be worse than useless — it could falsely flag working code or miss real bugs. Severity ratings, line-specific issues, and recommendations against an unread codebase would be invented, not observed.

**To unblock, please grant one of:**
1. Approve `mcp__claude_ai_mcp-server__forgejo_forgejo_get_file` for owner `zgaetano`, repo `dragonrelay` — preferred, matches your original instruction.
2. Approve `Bash` so I can `find` and `Read` the files if a local clone exists on this machine.
3. Paste the file contents directly into the conversation.

Once any of those is available, I'll produce the ISSUES / GOOD THINGS / RECOMMENDATIONS review against the spec criteria you listed (correctness, 401-vs-403, setup TOCTOU race, backfill goroutine ctx handling, build/vet bugs, etc.).
