[T6.3] Unlock 200K → transfer released_pool + burn rest

[realproject7]

Epic: #1229 · Spec: §5.3, §4.3, §8 Phase 6 · Type: OPERATOR · Estimate: 0.5 day

Scope

Unlock the 200K PLOT from Mint Club Locker and distribute per milestone tier.

Milestone reference (per §4.3)

Tier	FDV threshold	Released	Burned
🥉 Bronze	$100K	10% (20K)	90% (180K)
🥈 Silver	$1M	30% (60K)	70% (140K)
🥇 Gold	$5M	50% (100K)	50% (100K)
💎 Diamond	$10M	100% (200K)	0%

Sub-Bronze (FDV < $100K): 0% released, 100% (200K) burned — handled differently (see T6.1 sub-Bronze branch).

Steps

1. Call unlock() on Locker (now possible since unlockTime ≤ now)
2. Transfer released_pool PLOT to the MerkleClaim contract address (from T6.2 — the new T2.7-revised contract with sweep/deadline)
   • released_pool is from T6.1 output:
     • Bronze → 20,000 PLOT
     • Silver → 60,000 PLOT
     • Gold → 100,000 PLOT (50%, NOT 60%)
     • Diamond → 200,000 PLOT
3. Transfer (200,000 − released_pool) PLOT to the dead address (0x000000000000000000000000000000000000dEaD)
   • This is the milestone-burn — preserved from v4 mechanic
4. Record BOTH transaction hashes in this issue

Verify

• MerkleClaim contract balance equals released_pool
• Dead address received 200K − released_pool
• Operator wallet balance returns to pre-lock state (minus gas)

Sub-Bronze case

If T6.1 aborted (FDV < $100K): skip the Merkle transfer entirely. Burn all 200K to dead address. Record single burn tx. T6.2 was also skipped in this branch.

Acceptance

• Unlock tx succeeded
• released_pool value matches T6.1 output AND matches the §4.3 tier table above (especially Gold = 100K not 120K)
• If non-sub-Bronze: transfer to MerkleClaim tx hash recorded
• Burn tx hash recorded
• Balances verified on Basescan
• Sub-Bronze branch: single burn tx of 200K, no Merkle transfer

Dependencies

T6.1 (released_pool value), T6.2 (MerkleClaim address — only for non-sub-Bronze)
