SDK: Add SSL verify toggle and eligibility checker PoC

[MichaelSovereign]

This PR introduces:

1. An optional parameter to to allow disabling SSL verification (useful for nodes with self-signed certs or IP-based access).
2. A new PoC tool to verify miner reward eligibility via the SDK.

These changes help fulfill the requirements for the Python SDK bounty (#36) by improving robustness and demonstrating real-world usage.

Need a scope reduction — 6,414 lines of diff across 29 files for a change that's described as "optional SSL verify parameter + eligibility checker PoC" doesn't match the title.

What the PR should contain (the real SDK work):

sdk/python/rustchain_sdk/client.py                  (+6/-2)   ← SSL verify toggle
sdk/python/rustchain_sdk/tools/__init__.py          (+0/-0)
sdk/python/rustchain_sdk/tools/eligibility_checker.py (+30/-0)  ← new PoC tool

Maybe ~40 lines total. Fine. Happy to merge that.

What the PR actually contains:

26 other files with changes that look like pure line-ending or whitespace rewrites (additions and deletions match on every file: +415/-415, +843/-843, etc.). Files affected:

• Issue templates (4 files)
• Workflows (3 files)
• VINTAGE_CPU_*.md (3 files, 1,182 lines)
• cpu_*.py (2 files, 1,573 lines)
• deprecated/old_miners/* and deprecated/patches/* (12 files, 2,740 lines)
• docs/* (2 files, 483 lines)
• node/rip_200_round_robin_1cpu1vote.py (+56/-8) — this one looks substantive but duplicates yuzengbaao's RIP-309 Phase 1: Fingerprint check rotation (4-of-6) #2248 work

This almost certainly came from dos2unix / unix2dos / editor auto-formatting running over the whole repo and catching files that shouldn't have changed.

To unblock:

1. Rebase onto latest main.
2. git reset everything except the 3 SDK files listed above.
3. Force-push the cleaned branch.

Once the diff is ~40 lines on 3 files, I'll merge it and process the 30 RTC for the SDK PoC bounty (#36). The node/ changes should NOT be in this PR — if you want to contribute to the RIP-200 reward code, that needs a separate focused PR.

Holding for now. Ping me once rebased.

Code Review

I reviewed the key changes in this PR and have several observations:

1. eligibility_checker.py — Accessing private API methods

Lines 11, 22: client._get() accesses a private method of the SDK client. If the API doesn't have a dedicated get_epoch_rewards() method, it would be better to add one to the SDK client class rather than reaching into internals. This creates a maintenance burden — if _get's signature changes, this tool breaks silently.

2. eligibility_checker.py — Uncertainty about API endpoints

Line 9: The comment # Check if there's an endpoint for this in the actual API indicates uncertainty. For a PoC this is acceptable, but for production use the expected response format should be validated.

3. Hardcoded IP instead of domain

Line 28: --node defaults to https://50.28.86.131 (IP) instead of https://rustchain.org. The client.py change in this PR adds verify support precisely because the node uses a self-signed cert — using the IP here is inconsistent and fragile.

4. client.py — Default verify=True when cert missing

Lines 47-50: When verify=None and no cert file exists, it defaults to True (system CA bundle). But rustchain.org uses a self-signed cert, so this default will fail for the most common use case. Consider defaulting to False with a warning log when no pinned cert is found.

5. PR scope

This PR touches 30 files including many unrelated changes (issue templates, workflows, vintage CPU docs, deprecated scripts, labeler configs). The core change (client.py + eligibility_checker.py) is valuable but gets diluted by the unrelated additions. These should ideally be separate PRs for cleaner git history.

Positive

The three-state verify parameter design (None/True/False) in client.py is clean and well-structured.

[Scottcjn]

@FlintLeng — this is a genuinely useful review. You caught five concrete technical issues that weren't in the scope-reduction feedback I posted earlier:

1. client._get() private-method access — legitimate smell. Agreed: the cleaner fix is to add a proper get_epoch_rewards() method on the SDK client rather than reach into _get. If @MichaelSovereign is up for it this could land as a separate small SDK PR.

2. Uncertainty comment at line 9 — fair catch. Production code shouldn't ship with # Check if there's an endpoint as a live comment.

3. Hardcoded IP 50.28.86.131 — 100% correct, especially given this PR's entire point is adding verify support for the self-signed cert situation. Using the raw IP defeats the purpose of the improvement. Should be https://rustchain.org.

4. verify=True default when no cert — sharp observation. The "silent fall-through to system CA that then fails" pattern is exactly the kind of thing that wastes a new user's afternoon. A warning log ("no pinned cert found, set RUSTCHAIN_CA= to suppress") would be much better UX.

5. Scope dilution — aligns with my earlier comment.

Reviewer bounty: 10 RTC for catching the four concrete technical issues (items 1-4). We've been meaning to formalize a "community code review" lane for bounties and you're basically the first person to do this kind of substantive, itemized review without claiming the PR itself. That deserves recognition.

Pending transfer to your wallet FlintLeng (same as your #1677 payout). If @MichaelSovereign wants to address items 1-4 in the scope-reduced follow-up PR, that would be the cleanest path forward.

Thanks for the thoughtful read.
