-## #107 — Indoor spawn wedge: player stuck (in air / in wall) when logging in inside a building
-
-**Status:** OPEN
-**Severity:** HIGH
-**Component:** physics / player-mode entry (`PlayerModeAutoEntry`, spawn teleport handling)
-
-Reproduces 3-for-3 (2026-06-10) when `+Acdream` logs in INSIDE the Holtburg inn (character
-logged out indoors): player-mode auto-entry fires (`auto-entered player mode` in the log),
-then the player hangs in the air / in a wall and movement input is ignored. One stuck run
-showed `live: teleport started (seq=1)` with no completion — ACE pushing a position
-correction that never resolves. The #106 gate-2 `isSpawnGroundReady` hold checks
-`SampleTerrainZ != null` (outdoor TERRAIN under the spawn) — an INDOOR spawn's ground is
-the cell floor, not terrain, so the relationship between the hold, the spawn teleport, and
-indoor grounding needs investigation. Outdoor spawns enter fine. Workaround: none from the
-client; relaunching re-wedges because the character is parked indoors.
-Apparatus when picking this up: `ACDREAM_CAPTURE_RESOLVE` + `ACDREAM_PROBE_RESOLVE` on a
-login-indoors run; logs `flood-fix-gate2.log` / `flood-fix-gate3.log` (untracked) hold the
-stuck-run output.

+## #107 — Indoor-login spawn wedge — [DONE 2026-06-10 · 1090189]
+
+**Status:** DONE (live-verified incl. ACE's own poisoned teleport; final indoor
+logout→login gate pending user)
+**Closed:** 2026-06-10
+**Commit:** `1090189`
+**Component:** physics / player snap, teleport arrival, outbound wire pairs
+
+**Root cause (capture `resolve-107-login1.jsonl` + dat scan):** ACE restored a
+POISONED (cell, position) pair — cell `0xA9B40162` (one building) with a position
+inside `0xA9B40171` (a different building 55 m away). The entry snap trusted the
+claim verbatim → fake-grounded limbo (no contact plane/walkable; zero-move
+resolves short-circuit) → first movement demoted the claim to outdoor
+mid-building → 2.4 m fall through the cottage floor onto the terrain under the
+house. Second shape: the PortalSpace teleport-arrival detection gated on
+`differentLandblock || farAway>100m` (invented) — ACE's same-landblock short-hop
+corrections matched neither → movement input frozen all session.
+
+**Fix (four legs, retail-anchored):** (1) `PhysicsEngine.Resolve` (player snap)
+runs retail `AdjustPosition` first (SetPositionInternal :283892 step 1;
+AdjustPosition :280009) — `[spawn-adjust]` logs corrections; (2) the deferred
+indoor `seen_outside → adjust_to_outside` sub-fallback completed (+
+`CellPhysics.SeenOutside`); (3) PortalSpace arrival = any player position update
+(holtburger-conformant); (4) outbound wire pairs self-consistent (landblock
+frame from the resolver's full cell id, not the position) + the gate-2 hold
+extension (`IsSpawnCellReady`). Live verification: ACE sent a same-lb dist=69.8
+teleport whose destination was ANOTHER poisoned claim (`0xA9B40150`) — arrival
+completed, `[spawn-adjust]` corrected, player fully controllable.
+Tests: `Issue107SpawnDiagnosticTests` (3 dat-backed conformance facts).
