Add SpectraHook hook on base

[hooklist-generator]

Summary

Review: hooks/base/0x972fd516470c0e1841211c51c37ab2f7dfe44040.json

Address Flags

Address 0x972fd516470c0e1841211c51c37ab2f7dfe44040: lower 14 bits = 0x4040 & 0x3FFF = 0x0040 = 64 = bit 6 only → afterSwap: true, all other flags false. ✓ Matches the hook file exactly.

Source confirms: getHookPermissions() sets only p.afterSwap = true.

Properties

Property	Filed	Verdict
dynamicFee	false	✓ No beforeSwap, no updateDynamicLPFee() call
upgradeable	false	✓ Fully immutable; source_meta.json confirms proxy: false
requiresCustomSwapData	false	✓ _afterSwap ignores hookData entirely
vanillaSwap	false	✓ Correctly false — _harvest() executes a nested poolManager.swap() inside afterSwap, which is a disqualifying condition
swapAccess	"none"	✓ No beforeSwap; afterSwap has no access control gating
