EasyCord v5.53.0 — Framework Hardening Phase 1

EasyCord v5.53.0 — Framework Hardening Phase 1

Overview

Phase 1 of the v5.53 Framework Hardening roadmap. Five tasks landed:
verified-open bug fixes with full regression coverage, cooldown architecture
cleanup, and EventBus observability improvements.

What's in this release

Bug fixes

• B-007 — Invite cache leaked memory across guild removals; now pruned in
  _on_guild_remove.
• B-015 — _grant_level_reward caught Forbidden only; HTTPException
  parent class now caught so all Discord errors are handled.
• B-016 — auto_role post-sleep add_roles failed silently on NotFound
  and generic HTTPException; both now absorbed.

Architecture improvements

• Single bot-level _cooldown_cleanup_loop replaces per-callback sweep tasks
  (which were unreliable at import time). A _COOLDOWN_MAX_ENTRIES=50_000 hard
  cap with oldest-bucket eviction prevents unbounded growth.
• Cooldown registry entry is now stored on the built callback and removed from
  bot._cooldown_registries when the owning plugin is unloaded via
  remove_plugin — previously these entries were permanent zombies.

Regression net (new tests)

1513 tests total (+75 from v5.52.0):

• test_bot_permissions_adoption.py — 16 tests (B-021 structural guard)
• test_cli_scaffold.py — scaffold collision regression
• test_cooldown_cleanup.py — 10 tests (expiry, cap eviction, lifecycle)
• test_event_bus.py extensions — EventBus observability
• test_p1_bug_sweep.py — B-007/B-015/B-016 regressions
