Note

High Risk
Changes core pausing/cooldown behavior and adds new storage/state (nonSecurityCouncilCooldownEnd, per-type expiries) in an upgradeable security-critical contract, so incorrect logic or storage assumptions could lock/unlock functionality unexpectedly.

Overview
Refactors PauseManager to replace the single global pauseExpiryTimestamp with per-PauseType expiry tracking (pauseTypeExpiryTimestamps) and a new nonSecurityCouncilCooldownEnd that enforces a pause window (additional types can be paused during the first PAUSE_DURATION) followed by a cooldown where non-security-council pausing is blocked.

Adds explicit security council indefinite pausing semantics: pauseByType by SECURITY_COUNCIL_ROLE sets expiry to uint256.max and emits PausedIndefinitely, while unPauseByType now blocks non-SC from unpausing indefinite pauses via OnlySecurityCouncilCanUnpauseIndefinitePause. Introduces resetNonSecurityCouncilCooldownEnd() (SC-only) and emits NonSecurityCouncilCooldownEndReset.

Updates hardhat tests and yield-manager controls to match new timing/emit behavior and adds a short doc (pause-by-type-flow.txt); updates LineaRollupV7.1.abi to reflect the new pause manager surface (new getter/event/function/error).

not sure about the triple-nested if-else blocks 😅

[kyzooghost]

should we use early returns instead?

if security_council ... -> early return
if past_cooldown ... -> early return
if in_pause_window ... -> early return
revert...

[thedarkjester]

you still need to set the pause and emit and adding another function just for that felt messier.
