The previous README had multiple inconsistencies discovered during ADR audit (Tâche 6 Phase A) : - Index table listed wrong titles for ADRs 0010-0021 (looked like an aspirational forecast that never matched reality) - Listed entries for ADRs 0011 (validation library) and 0014 (gRPC) but these files do not exist in the repo - 0024 (BDD Test Organization) was missing from the detail list - Template still showed the F1 format (* Status:) which is now obsolete (cf. previous commit homogenizing all ADRs) - Decorative emojis on every status entry of the index This rewrite : - Index table regenerated from actual file contents (title from H1, status from `**Status:**` line). Single emoji-free format. - Notes that 0011 / 0014 are not currently in use (reserved). - Updated template block matches canonical format adopted in homogenization commit. - Status Legend extended with Approved (used by ADR-0017), Partially Implemented (0009, 0013), Deferred, etc. - Added note that 0026 is the next free number for new ADRs.
