13/// Deliberately decoupled from the RAM `MemoryProfile` (64/128/512 MB): this is
14/// a *disk* file, and tying it to the profile silently refused persistence on
15/// large repos under Low/Balanced, forcing a cold rebuild on every call (the
16/// perpetual "index warming" of issue #249). 512 MB compressed covers
17/// essentially every real repo; RAM pressure is governed separately by the
18/// eviction orchestrator (which measures real heap).

27/// refused at dispatch so the host's native editor handles edits instead.
28///
29/// Deliberately narrow: only the dedicated edit tools are blocked — `ctx_edit`
30/// (str_replace) and `ctx_patch` (anchored, #1008). LSP refactor
31/// (`ctx_refactor`) also exposes read-only sub-actions (references/definition),
