fix: add authentication to unprotected write endpoints

[BossChaos]

1. passport_server.py: Require X-API-Key for passport CRUD and repair/benchmark logs
2. sophia_api.py: Require X-API-Key for /sophia/inspect fingerprint submissions
3. contributor_registry.py: Add IP-based rate limiting to /register (5/hour)
4. payout_ledger.py: Require X-API-Key for ledger creation

Prevents unauthorized data modification and spam across 4 critical APIs

PR Review: Authentication for Write Endpoints (PR #4071)

Author: @BossChaos
Scope: 5 files changed
Labels: BCOS-L1, size/S, ci

Summary

Adds API key authentication to protected write endpoints across multiple services + adds rate limiting to contributor registry.

Files Reviewed

• contributor_registry.py — Rate limiter added to / index
• passport/passport_server.py — API key for api_create
• payout_ledger.py — API key for api_ledger_create
• sophia_api.py — API key for inspection submissions

Assessment: ⚠️ Good with Bug

1. Security improvement — API key enforcement prevents unauthorized writes. ✅

2. Rate limiter — In-memory rate limiter on the contributor registry is a good defense-in-depth measure. ✅

3. 🚨 Bug found in passport/passport_server.py:

if not req_key or req_key != os.environ.get("PASSPORT_API_KEY", ""):
    return jsonify({"error": "unauthorized"}), 401
    return jsonify({"error": "machine_id required"}), 400  # ← DEAD CODE

The second return statement can never be reached — the function already returned. This looks like a copy-paste artifact. Should be removed.

Bug bounty: +10 RTC if confirmed and fix requested.

Est. Reward: Security-focused — 15-25 RTC
Recommended: Request changes (fix dead code line)

Closing per branch-contamination audit (2026-05-09).

This PR is part of a 161-PR cluster from your account where the diff carries files unrelated to the claimed fix. Specifically, 128 of 161 PRs in this batch modify .github/workflows/bottube-digest-bot.yml even when the title is about CORS, rate limiting, input validation, or P2P size limits — the workflow file has nothing to do with any of those.

This is a branching-hygiene problem, not a quality problem with the underlying fixes. The pattern means:

1. Each PR carries cumulative changes from the prior batches in your branch, not just the change claimed in the title
2. Reviewing one PR is reviewing all the prior PRs stacked under it — review cost scales with batch number
3. Merging one PR pulls in everyone else's prior work — high regression risk

To get back to paid status:

1. Pause the batch-fix factory
2. git checkout main && git pull
3. For each fix you want to claim, create a fresh branch off main:

   git checkout -b fix/<single-issue-slug> main
   # apply ONLY the change for that issue
   git commit && git push
   gh pr create
   

4. Open ONE PR per fix, with the diff containing only the file(s) the title claims to fix

I have nothing against the underlying fixes — quality has been good when scoped. But contamination at this scale is unreviewable, and Faucet Tiers policy requires clean diffs for security claims.

Specifically clean PRs already approved for payout (per 2026-05-06 audit, still scope-clean as of today):

• fix: add thread-safe concurrency protection to DramaArcEngine.start_arc #3239, fix: resolve TLS verification inconsistency in mac miner transport probe (#2282) #3967, security: consolidate info leak fixes (PRs #3946 #3956 #3957 #3961 #3962 #3963) #3979

These will be paid via the admin /wallet/transfer flow.
