docs: T5 comprehensive gate verdict - PARTIAL PASS; #108/#109/#97 closed, #117-#120 filed

The single comprehensive visual gate (2026-06-11, user-driven):

CONFIRMED (user axioms): doors block both ways incl. off-center (#99
visual pass), cellar descent/ascent clean + #108 grass-sweep GONE, inn
2nd floor clean (#97 CLOSED), interiors stable through doorways incl.
edge-on, #109 far-door oscillation GONE, formerly-popping stairs now
stable at all ranges. The entire T6/BR-7 collision port passed 100%.

REMAINING (render, filed at mechanism level - no live whack-a-mole):
- #117 aperture-shaped see-through: doors/interiors visible through
  terrain hills and through nearer buildings (the far-Z punch erases
  occluder depth at aperture pixels). Decomp direction:
  DrawPortalPolyInternal depth state vs draw order.
- #118 character clipped + vanishes momentarily on house exit
  (viewer-indoor/player-outdoor transition frames; local-player
  partition / aperture-clip suspects).
- #119 old-tower stairs partially invisible + extraneous water barrel
  (pre-existing); T5-log lead: [up-null] 0x010002B4 + 0x010008A8
  cached EMPTY render data, permanently invisible.
- #120 [pv-ERROR] in-place propagation tripwire at depth 128 on the
  cottage interior cells (T2 convergence invariant break, self-detected
  during the gate) - investigate FIRST.

Rain-indoors not verifiable (clear weather).

+## #117 — Aperture-shaped see-through: doors/interiors visible through terrain hills and through nearer buildings
+
+**Status:** OPEN
+**Severity:** HIGH (the most visible remaining render artifact post-port)
+**Filed:** 2026-06-11 (T5 comprehensive gate, user items 11a+11b)
+**Component:** render — aperture depth discipline (the T1 punch pass)
+
+**Symptom (user, axioms):** (a) "looking downhill I can see certain parts
+of houses (not everything) like doors and some textures" through the
+terrain; (b) "when I'm behind a house I can see the openings on the house
+behind that house through the house in front of me, like doors and
+windows." Both shapes are APERTURE-shaped (doors/windows), which points at
+one mechanism: the far-Z punch erases the depth of NEARER occluders
+(terrain hills, closer buildings) at the punched aperture pixels, so
+interior content + door entities (dynamics drawn last) paint over them.
+
+**Diagnosis direction (mechanism, not live-probing):** decomp
+`DrawPortalPolyInternal` (Ghidra 0x0059bc90) for the punch's depth STATE —
+retail either depth-tests the punch polygon against the existing buffer
+(only punching where the aperture is actually visible) or relies on
+far→near per-building draw order so nearer geometry re-establishes depth
+AFTER the punch. Compare against the T1 (`579c8b0`) punch pass wiring.

+## #118 — Character clipped + disappears for a moment when exiting houses
+
+**Status:** OPEN
+**Severity:** MEDIUM-HIGH (every house exit, brief)
+**Filed:** 2026-06-11 (T5 comprehensive gate, user item 10)
+**Component:** render — dynamics handling at the indoor→outdoor transition
+
+**Symptom (user):** "We get clipped and disappear when we exit houses.
+Like when we are just outside for a moment." Transition frames where the
+viewer is still indoors and the player is just outside the door.
+
+**Suspects (in order):** (1) the LOCAL player entity's partition in
+`InteriorEntityPartition` — T1's rule routes `ServerGuid != 0` to
+Dynamics (never dropped); the local player may carry ServerGuid==0 and
+fall into a per-cell static class that drops when its cell isn't in the
+flood; (2) the landscape-through-aperture pass's plane clips slicing the
+player if it draws in that pass ("clipped" wording). Check the partition
+first.

+## #119 — Old tower: stairs partially invisible + extraneous water barrel; two meshes permanently invisible at startup
+
+**Status:** OPEN
+**Severity:** MEDIUM (pre-existing — "same issue as before" per the user)
+**Filed:** 2026-06-11 (T5 comprehensive gate, user items 9+13)
+**Component:** render — mesh upload / content inclusion
+
+**Symptom (user):** the old tower has missing stair parts (pre-existing;
+the tower stairs ARE visible in retail — user axiom recorded 2026-06-11
+in the render digest) and shows a water barrel that retail doesn't.
+
+**Lead (from the T5 launch log):** exactly two
+`[up-null] upload returned null for 0x00010002B4 / 0x00010008A8 — caching
+EMPTY render data (permanently invisible)` lines at startup. Identify
+which models those are (likely GfxObjs 0x010002B4 / 0x010008A8 — plausibly
+the stair parts) and why `ObjectMeshManager`'s upload returned null; the
+"permanently invisible" cache makes any transient failure sticky. The
+barrel is a separate static-inclusion question (which cell owns it, and
+is it admitted by a view it shouldn't be).

+## #120 — [pv-ERROR] in-place propagation tripwire: convergence invariant broken at depth 128 (cottage interior cells)
+
+**Status:** OPEN
+**Severity:** HIGH (self-detected invariant break in the new flood growth)
+**Filed:** 2026-06-11 (T5 launch log; fired during normal cottage play)
+**Component:** render — PortalVisibilityBuilder in-place growth (T2/BR-4)
+
+**Evidence:** `[pv-ERROR] in-place propagation tripwire at depth 128 on
+cell=0xA9B40175 / 0xA9B40174 / 0xA9B40162 — convergence invariant broken,
+investigate` (3+ firings in the T5 session, exactly the cottage interior
+cells the user was walking). T2's in-place growth (which replaced the
+`MaxReprocessPerCell=16` cap) re-propagated one cell's view 128 times
+within a single build — a re-emission cycle the dedup misses, or growth
+ping-ponging through a reciprocal portal pair. May be load-bearing for
+#117/#118 (runaway view growth → wrong clip/punch volumes). Investigate
+FIRST among the post-T5 set: loudest signal, cheapest repro (the tripwire
+self-reports), and a correctness invariant of the new code.
