S213: replace إحياء v4 with server-hardened isteidad; fix build-timeout (drop cache-bust line + voicefixer2)

S213: replace إحياء v4 with server-hardened isteidad; fix build-timeout (drop cache-bust line + voicefixer2)

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

S212: deploy engine_isteidad_server.py (server-hardened isteidad)

S212: deploy engine_isteidad_server.py (server-hardened isteidad)

S209: fix relative import depth (.utils -> ..utils) in vendored AP-BWE

S208: log real exception in apbwe_wrapper import failure

S206: vendor AP-BWE as SIDON replacement in ihya v4 cascade

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

S205: re-confirm engine_ihya_v4.py present

S204: add engine_ihya_v4.py (replaces ihya v3 in v11.2 slot)

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

S200: add engine_itiqan_v6_server.py (server-optimised الإتقان)

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

S191: add engine_safaa_v5.py (continuous DF3 blend, S190 WPE guard, /app/deep-filter path)

S190: WPE runs in a timeout-guarded subprocess instead of unbounded in-process

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

S188: self-healing deep-filter resolution + real exec self-test

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

S186: restore DF3 per-pass timeout, add per-class timeout guard (was nuking all 4 passes silently)

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

S185: flush log to disk + cap DF3 pass timeout 55s

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

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

S170: add /app/deep-filter to engine search list; copy binary

S169b: fix final encode — libmp3lame + mono + 320k + sys.exit on fail

S167: always expose engine_log/engine_rc/engine_error/used_fallback

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

S164: re-upload engine_safaa_v3_fixed.py (was 0 KB — upload_file positional-arg bug)
