S214: remove إحياء v4 entirely, isteidad-server takes v11.2; clean requirements.txt (cache-bust + voicefixer2 gone)

S205: v11.2 → engine_ihya_v4.py + _is_ihya dispatch branch

S200: app.py v11.1 → engine_itiqan_v6_server.py

S191: app.py v11.0 → engine_safaa_v5.py

S189: drain buffered stdout on engine timeout instead of discarding it

S187: recognize Safaa's real log tags — progress was frozen for the whole run

S185: stop masking killed/bad-score jobs, force Itiqan aggressive everywhere, harden deep-filter

S180: Itiqan (v11.1) always runs --aggressive

S179: aggressive-mode الصفاء (S167) + restore v10.0/v9.0/v8.5/v8.0/v7.0, drop dead v8.9/v8.7/v8.4

S176: fix hung-engine deadlock — communicate(timeout) replaces blocking stdout loop

S175: safaa v4 (DF3 path fix, nara_wpe, --tier/--mujawwad, rm v3_fixed)

S174: SV-C1 safaa positional args, SV-C2 tier chunked, SV-C3 indent, SV-C4 stale files

S173: repair cmd corruption + safaa WAV output + proc timeout + history whitelist

S171: wire tier/mujawwad from upload form → engine CLI

S167: always expose engine_log/engine_rc/engine_error/used_fallback

S165: safaa engine — skip --iterations/--ref (argparse crash → fallback)

S163: v11.1 → engine_itiqan_v6_official.py (الإتقان v6)

S162: SV-B1 isteidad filename, SV-B2 keepalive localhost, rm tajalli+itiqan-v5, add safaa-v3

S149: الصفاء in ENGINE_SCRIPTS (server)

server: update isteidad v12→v21 + add companion modules

S95: fix dead engines + default v11.0 + refs_warm check

fix: MAX_CONTENT_LENGTH 6MB → 512MB — allow large file uploads

S64: fix 5 bugs — dedup v11.0, RAM guard, watchdog, engine_log, status

SRV-v11: engine_tajalli + itiqan + isteidad + deep-filter + ENGINE_SCRIPTS v11.0/v11.1/v11.2

Replace app.py with production v5 + v11.0 التجلي engine
