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)

S212: add psutil for isteidad-server memory guard

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

S212: add git to apt-get install (needed for pip git+https installs)

S210: voicefixer -> voicefixer2 (fixes np.complex/librosa crash)

S210: VoiceFixer Mode 2 for is_katam-flagged audio

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

S208: log real exception in apbwe_wrapper import failure

S207: broaden import guards (ImportError -> Exception) — fixes voicefixer/librosa np.complex crash taking down whole module

S206: add torchaudio for AP-BWE

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

S204: v11.2 → engine_ihya_v4.py, drop --aggressive for ihya

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

S202: add torch+voicefixer, pre-warm BWE weights at build time

S201: v11.2 → engine_ihya_v3.py + ihya dispatch branch

S201: add engine_ihya_v3.py (replaces isteidad 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

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

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)

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

S156: remove engine_v100 from bootstrap

S155: engine_itiqan_v6_official.py

S151: add engine_itiqan_v5-3.py (v12.0)

S150: ensure numpy scipy librosa soundfile installed

S149: zombie killer + engine timeout

S149: fix BASE NameError — move before JOBS_FILE

Fix JOB_EXPIRED: BASE persistence, bootstrap order, remove duplicates
