research(track-a): recover world minimap static G1

[blakinio]

Objective

Continue TIBIA-RE-WORLD-MINIMAP from merged corrected G0 promotion #551/#552 and execute the next bounded current-build static discriminators for F11/F12/F13.

PR #475 remains read-only dependency state and grants no runtime/login/mutation authority to this task.

Exact current package

Both disposable producers matched the trusted current Track A Linux-client fence:

The temporary producer workflow has been removed. Current PR diff contains exactly three task-owned documentation/evidence paths.

G0/v1 correction

WM-MINIMAP-AUD-001 remains enforced. G1 does not reuse the rejected nearby-relative-table heuristic.

The v1 Qt method-case mapping is accepted only where the exact method-ID lineage, bounds check, relative table, add-to-base and indirect jump were all proven. A later v1 convenience scan for first_direct_call could cross into an adjacent method case, so every such inferred call field is rejected. Producer v2 exists specifically to provide direct bounded disassembly without that attribution heuristic.

Result

F11 — PARTIAL -> PARTIAL, materially strengthened

Direct current-build evidence now establishes:

TMinimapController internal state pointer = controller +0x48
current layer                             = int32(state +0x60)
controller-enforced layer range           = 0..15 inclusive
visible width                             = int32(state +0x84)
visible height                            = int32(state +0x88)

Floor-up decrements and floor-down increments the same layer field. setCurrentLayer clamps to 0..15, recomputes the minimap view and emits the layer-change notification. Visible-area refresh consumes actual QML QQuickItem width/height from the controller's quick-item owner before recomputation.

F12 — PARTIAL -> PARTIAL, materially strengthened

TMinimapMarkerStorage is corrected to three Qt signals followed by onDelayedCallback and setMarkersFromMinimapMarkerFile. The save signal carries shared MinimapMarkerFileContent ownership. onDelayedCallback checks byte storage+0x40 before entering the save-side virtual path.

Current exact evidence retains minimapmarkers.bin, protobuf marker type names, serializer/deserializer error paths and marker action families. The bounded FileDescriptorProto scan returned MINIMAP_DESCRIPTOR_CANDIDATES=0; exact protobuf field numbers/types therefore remain UNKNOWN, not absent.

F13 — PARTIAL -> PARTIAL, materially strengthened

Direct current method-case disassembly binds the main transform entries to their current helpers. For projection mode 0:

forward: X=x+32*L, Y=y+32*L
inverse: x=X-32*L, y=Y-32*L, layer=L
static oracle: (3,5,7) -> (227,229) -> (3,5,7)

setAdditionalColumnsAndRows stores four signed 32-bit values at viewport +0xa0..+0xaf and schedules recomputation. translateBySubfieldOffset component-wise adds the supplied two-integer offset to the viewport pair at +0x88.

Complete non-zero projection/shearing/scale/rounding semantics remain UNKNOWN.

This G1 does not consume or replace #475's physical causal frontier.

Current main observed during closeout: f75cdbf8f408812d9508d1e076bdc9a35f82f5ac. Compare against the prior source head showed ahead_by=9, behind_by=4, merge base 724f020d..., with only the three G1 task-owned paths in the diff. PR remains mergeable and Draft. An independent auditor must recheck live main/head freshness before promotion/merge.

Remaining gate

There is no independent review submission on PR #593 in this implementing session. Repository completion policy requires a fresh validator role/session; the implementer cannot self-approve the research evidence.

BLOCKER=REQUIRED_FRESH_INDEPENDENT_RESEARCH_DOCUMENTATION_AUDIT_UNAVAILABLE_IN_CURRENT_SESSION

After a fresh independent audit reports zero material findings: recheck the exact head/current main, resolve any audit remediation, promote/merge under repository policy, archive the task and release lifecycle state.
