ci(track-a): independently audit native-login closeout helpers

[blakinio]

Terminal audit disposition — consumed by native-login promotion #577

Status: CLOSED UNMERGED AS AUDIT-ONLY / CONSUMED.

This PR independently falsified the frozen source #528 head 8e029f5849a1d51f69486adcc3716c80f139e60e without physical runtime, real credentials, login, GUI input or gameplay.

Terminal accepted audit results

Helper/source validation:

current_sha_native_login_gate.py             py_compile PASS
current_sha_secret_ingress.cpp               compile PASS
experimental_character_control_current.cpp   compile PASS
sealed memfd + complete seal set              PASS
SCM_RIGHTS synthetic same-UID/PID ingress     PASS
synthetic credential payload/response         PASS
exact current public package fence             PASS
source current-SHA gate                        PASS
REAL_SECRET_ACCESS=false
OFFICIAL_CLIENT_EXECUTED=false

Targeted strict table audit:

run 32242788755 = SUCCESS
TGameClient                       table=0x1d903c4 methods=44 switch LEA=0xd1910a
TCharacterSelectionController     table=0x1d98fe4 methods=26 switch LEA=0xd51c90
TAuthenticationProcessController  table=0x1d8ff20 methods=51 switch LEA=0xd0f5ff
STRICT_ALL_NATIVE_LOGIN_QMETA_TABLES=PASS
RAW_CLIENT_RETAINED=false

Falsification repair history

Two earlier audit generations are explicitly audit-method failures, not source findings:

1. run 32242202262: audit cleanup trap removed the temporary client between steps after helper compile/synthetic ingress/package fence had passed;
2. run 32242561205: source gate and TGameClient/CharacterSelection strict bindings passed, but coordinator parser imposed an inapplicable requirement that TAuthenticationProcessController be discovered as a relocation-backed static QMetaObject. The final targeted table-xref discriminator tested the actual claim and passed.

No material implementation finding remained after the independent audit. The result was consumed into coordinator evidence and source review 4971140006 = ACCEPT_WITH_EDITS, then clean promotion #577 passed exact-head CI/governance/native-auth validation and squash-merged as db41e9112383fd5993cba04437bbbd8f6963e6e7.

No temporary audit workflow from this PR is merged to main.
