KB: reconcile the context system with the day's work
- decomp-reference.md: the binary ATTRIBUTE-TABLE section -- 16-byte
{id,name,off+1,0} row format (alignment warning), the walker technique,
and the three recovered tables (Mech ids 21-56 incl the corrected
EyepointRotation@0x360 / RearFiring@0x410 / DistanceToMissile@0x400
labels; HeatSink 3-12; Torso 3-15; the weapon RearFiring 'b' marker).
- combat-damage.md: the REAR-FIRE + look-view system (roster survey: the
Blackhawk's ERMLaser_2/3 are the game's only rear weapons; every missile
rack forward), the missile mount-frame launch truth, and the BANKED
full Missile flight-model decode (three performances, proximity fuse).
- wintesla-port.md: post-Phase-4 closures (instability model live, F14
static filter baked, the footstep warm-up bug + its trace-cap lesson);
deferred list trimmed to F21/HRTF.
- AUDIO_FIDELITY.md: status block -- F14 FIXED, warm-up bug noted.
- open-questions.md: "which mechs used rear fire" answered from data;
remaining look-view key bindings noted.

## REAR-FIRE + look views (task #68, 2026-07-16) [T1]
|
||||
The pod had a rear arsenal + a five-state LOOK-VIEW system (all reconstructed + live):
|
||||
- **weapon.rearFiring @0x334** = the MOUNT SEGMENT page name contains 'b' (ctor marker @0x511aa2;
|
||||
the back ports `sitelbgunport`/`siterbgunport`). Roster survey: **the Blackhawk's ERMLaser_2/3
|
||||
are the ONLY rear weapons in the game** (both loadout variants; the Owens model HAS back ports
|
||||
but mounts nothing on them; every missile rack is forward).

- The mapper look machine (part_013.c:396-459; modes 0=fwd 1=left 2=right 3=BACK 4=down from the
|
||||
look buttons): on change it writes **EyepointRotation (mech+0x360)** — side yaw = the authored
|
||||
per-mech look angles (model rec +0x50-0x5c → mech 0x564-0x570), look-back = yaw π + lookBackAngle
|
||||
pitch — and re-arms each weapon's **viewFireEnable @0x3E0** (fwd = !rear, back = rear, else 0).
|
||||
0x3E0 is the fire gate (the Loaded→Firing transition, part_013.c:7689 — the old
|
||||
`useConfiguredPip` label) AND selects the HUD pips: the reticle registers each pip in group
|

1(front)/2(rear) from the RearFiring attr (part_014.c:5429-34) and draws the group in the mech's
