I own the named ETS table that backs all GtBridge derived-state caches and invalidate per-module entries when the module recompiles.

Cache consumers (styler call_sites, alias maps, function records, doc fetches, source paths, module→app lookups) read and write this table directly via :ets. I do not mediate reads or writes — I only react to %ModuleEvent{kind: :recompiled} from the EventBroker by deleting every entry tagged with the affected module.

Cache key shape places the module second so a single match-delete reaches every entry for a module regardless of the entry's :kind:

{:call_sites, mod, source_hash}
{:alias_map,  mod, source_hash}
{:functions,  mod, source_hash}
{:docs,       mod}
{:source_file, mod}
{:module_app, mod}

Public API

• start_link/1 — supervised start
• table/0 — name of the ETS table for cache consumers
• cached/2 — read-through cache helper for consumers
