//| Chart-level tuned indicator periods - ONE source of truth for     |
//| every consumer of "what period does this indicator run at".       |
//|                                                                  |
//| The 2026-08-16 menu pruning made ALL indicator parameters         |
//| tuner-owned (see Inputs.mqh). That leaves two consumers that must |
//| agree: the AI features (whose per-model tuned values persist in   |
//| the .nnw) and the classic votes + signal-DB key (chart-level,     |
//| configured once at OnInit). This file is the bridge: a gated      |
//| tuner INSTALL writes the winning periods here; the next attach    |
//| reads them BEFORE the classic signals are configured and BEFORE   |
//| the DB fingerprint is computed, so votes, DB key and tuner seeds  |
//| all describe the same indicators.                                 |
//|                                                                  |
//| ADOPTION IS RESTART-GRAINED BY DESIGN: an install mid-run changes |
//| the AI features immediately (fresh topology) but classic votes    |
//| and the DB key keep their init-time values until the next attach. |
//| Re-configuring framework signal indicators mid-run would need the |
//| ReInitADIndicators treatment (handle release, cache invalidation) |
//| for machinery that changes at most once per tuning install -      |
//| restart-grained is simpler and cannot leak handles.               |
//|                                                                  |
//| The DB SEMANTICS consequence is intended: the DB fingerprint      |
//| hashes these adopted values, so new periods = new database = the  |
//| per-pattern win-rate history never blends rows from two different |
//| indicator definitions (the January-August 2026 blending trap).    |
