runtime(track-a): promote verified native login E2E

[blakinio]

Objective

Promote the independently audited terminal result of existing native-login source PR #528 without merging its stale long-lived history or replaying credentials.

Clean promotion

Base: main@aaf6706cfcd02e70511e5fa7e9ef9b0d7e1f0d12
Final head: 31b252add74ac094067effd7bb3c0e4f888f09e4

Final compare: ahead_by=4, behind_by=0, exactly 23 paths: 22 canonical native-login evidence/prompt/helper/archive paths plus one temporary active Track A promotion-admission record. The temporary record has runtime_access:none and is removed in lifecycle closeout.

No credential-bearing workflow or temporary audit workflow is promoted.

Coordinator decision

Source review 4971140006: ACCEPT_WITH_EDITS, open material findings after repair 0.

Coordinator audit #575 independently closed the source validation gap without login/real credentials/client execution:

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 + required seals                PASS
SCM_RIGHTS synthetic ingress                 PASS
source current-SHA gate                      PASS
exact current public package fence            PASS

Targeted exact-build strict 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
OFFICIAL_CLIENT_EXECUTED=false
REAL_SECRET_ACCESS=false

Terminal E2E boundary

RESULT=SUCCESS_AT_PROOF_POINT
CHARACTER_ACTUALLY_LOGGED_INTO_GAME=YES
CAUSAL_PROOF=COMPLETE
STRUCTURAL_IN_GAME_AT_PROOF_POINT=PASS_3_OF_3

and later:

CURRENTLY_LOGGED_IN=NO
POST_HANDOFF_SESSION_STABILITY=FAIL_NOT_RETAINED
SECOND_SECRET_ATTEMPT=NOT_PERFORMED

No duplicate credential-bearing E2E was run for closeout.

Final exact-head validation

CI                                  32243674084 = SUCCESS
Track A governance                  32243673952 = SUCCESS
Track A native auth bridge          32243673903 = SUCCESS
promotion review                    4971210315
review threads                      0
main freshness                      behind_by=0

Safety

Coordinator audit/promotion used runtime_access:none: no physical client execution, real credential access, login, GUI input, gameplay, process-memory access, client mutation, transaction or session mutation.

After promotion merge, source #528 is closed unmerged as superseded, audit-only #575 closed unmerged as consumed, the temporary active promotion task removed, and the archive finalized in a lifecycle-only closeout.

Final coordinator promotion review on exact head 31b252add74ac094067effd7bb3c0e4f888f09e4: PASS pending only the already-running native-auth bridge check.

Verified:

• clean ancestry from main@aaf6706cfcd02e70511e5fa7e9ef9b0d7e1f0d12, no stale source-history merge;
• 22 canonical native-login evidence/prompt/helper/archive paths plus one temporary active Track A promotion-admission record required by governance;
• all 20 source-carried durable/helper paths use accepted exact source blobs;
• no credential-bearing or temporary audit workflow is promoted;
• independent audit #575 compiled/falsified all three current-SHA helper files with synthetic credentials only and confirmed exact current-package QMeta table control flow;
• source #528 review 4971140006 = ACCEPT_WITH_EDITS, zero material findings after repair;
• promotion preserves both RESULT=SUCCESS_AT_PROOF_POINT and POST_HANDOFF_SESSION_STABILITY=FAIL_NOT_RETAINED without claiming persistent login;
• no real credentials, login, client execution, GUI input or gameplay were used by coordinator audit/promotion;
• exact-head CI and Track A governance are SUCCESS; review threads are zero.

If exact-head Track A native auth bridge validation reaches SUCCESS and main remains the same ancestry base, this promotion is ready for squash merge. The temporary active promotion task must then be removed in lifecycle closeout.
