GE_* environment probes — consolidated list

Every getenv("GE_…") in the tree. The table prose is hand-curated; tools_pc/gen_env_probes.py re-greps the live sites and reports drift (NEW / GONE vars + a fresh file:line map) — run it before trusting the File:line cells. Last reconciled 2026-09-04 (M-51). All are env-gated: unset = zero behavior change, so they are safe to leave in a release build (they only cost a getenv on the guarded path). “Dead” below means the finding it was built for is closed — the probe is strip-candidate scaffolding, not that it does anything harmful.

Two classes:

Infra / live tooling

Env var File:line What it does Status
GE_PCDUMP port/fast3d/gfx_opengl.cpp:1079 (is_pcdump), gfx_opengl.cpp:700, port/src/video.c:188, port/src/config.c:46 (configGetFrameDump) Per-frame framebuffer PPM dump to $PCDUMP dir (verification-ritual golden captures, tools_pc/framediff.py/pixcount.py). Also settable via [Debug] FrameDump ini (env wins). M-33/D168: the writer now emits rows top-to-bottom — captures before that fix are vertically flipped. live
GE_INPUTSCRIPT port/src/input.c:306 Headless scripted controller-0 input: "<frame>:<tok>,…;…" (SUP/SDOWN/SLEFT/SRIGHT/SNONE sustain, buttons pulse). Sole input source when set. live
GE_INPUTLOG port/src/input.c:329, port/src/config.c:53 (configGetInputLog) Logs computed pad state (buttons + stick) each poll when non-zero. Also [Debug] InputLog ini. Also traces D165 menuptr est/tgt/eff/stick. live
GE_STARTMENU (+ GE_STARTMENU_PAGE, GE_STARTMENU_DIFF) src/game/lv.c:398-402 (#ifdef PORT) Boot straight into a front-end menu id (13=MISSION_COMPLETE, 10=BRIEFING, 7=MISSION_SELECT, 12=MISSION_FAILED, 6=MODE_SELECT); _PAGE=folder row (def 1=Dam), _DIFF=0..3. Crash-test a screen fast. live
GE_UNLOCK_ALL src/game/debugmenu_handler.c:1098 (get_debug_enable_all_levels_flag, #ifdef PORT) Mission-select shows every solo level (playtest jump-to-any-level aid). Cached in a static int c. live
GE_OPTIONSOVERLAY port/src/optionsoverlay.c:231 Force-enable the F10 port-layer options overlay (D184 / PR #10) regardless of ini. atoi != 0. live
GE_TEXPITCH port/fast3d/gfx_pc.cpp:924 (gfx_tex_pitch_fix, cached) =0 disables the D183 defensive de-stride in import_texture (default on). RC2/RC3 texture-shear A/B knob. live (RC3 not finished)
GE_TEXRAW port/fast3d/gfx_pc.cpp:1079 With GE_TEXDUMP, also dumps the raw pre-import source bytes (texdump/rNNN_f…_s…_WxH.bin) so a decode bug can be told from a source-data bug offline (D183). live (RC3 not finished)
GE_WRAPFIX port/fast3d/gfx_pc.cpp:3166 (gfx_set_wrap_fix) RC3 test override for the Video.WrapFix D74/D167 wrap-block path (atoi != 0 wins over the ini). live (RC3 not finished)
GE_SAVELOG src/game/file.c:46, src/game/file2.c:16 (SAVELOG macro), src/boss.c:749, src/game/objective_status.c:297,343 Traces the campaign save/unlock chain (objective completion → end_of_mission_briefing → fileWriteSave → EEPROM). Used to confirm D157. g_savelogObjOnce gates the per-criterion dump to the bossReturnTitleStage call. live (strip once a few more level boundaries are playtested)
GE_D160 src/boss.c:744, src/game/bondview2.c:791, src/aicommands.def:10055,10181,10236,10242,10247 (all #ifdef PORT) Dam exit-cutscene (D148/D160) diagnostic: trace points in bossReturnTitleStage, bondviewSetCameraMode, and AI cmds EndLevel/exit_level/CameraLookAtBondFromPad/CameraSwitch. Investigation in progress — user owes a GE_D160=1 Dam run. live
GE_DTEX port/fast3d/gfx_pc.cpp:1001 Per-import_texture param log (dims / line / size / lod / gen_mipmaps). Used to root-cause RC2 and D159. Kept as an inert diagnostic. live (RC2/RC3 not finished)
GE_TEXDUMP port/fast3d/gfx_pc.cpp:1020, port/fast3d/gfx_opengl.cpp:700 PPM dump of every uploaded texture + a fmt/siz/palfmt/palidx/pal[0..3] line. Root-caused D161 (Depot ceiling). Kept as an inert diagnostic. live (RC3 not finished)
GE_D116 port/fast3d/gfx_pc.cpp:1710,2362, src/game/textrelated.c:265,541 (cached ge_d116) HUD/text “X-mirror” (D114/D116) vbo/uv trace. D114/D116 CLOSED — NOT A BUG (M-33/D168): the captures were upside-down, not mirrored. Probe is now dead scaffolding — strip on the next cleanup pass. dead (D114/D116 closed)

Dxx diagnostic probes — finding closed unless noted

Env var File:line Finding / what it logged Status
