# Existing CG sender compatibility (offline only)

The existing current source sender at ED5A `3433030` has a 531-byte body.
Address-normalized body matching alone returns two pinned6891 candidates:
`3433090` and `3440E40`. The body contains the same `&initiativeId=` text in
both cases, so that text is not sufficient to choose one.

The exact corresponding call in current `3433030+F5` invokes `9A5040`.
Pinned `3433090+F5` invokes `9A5080`, independently uniquely matched to that
current helper by its complete function. Pinned `3440E40+F5` instead calls
`9A5270`, a different function with a different body. This excludes the second
candidate without treating similar request bodies as interchangeable.

The original component constructor `1E87120` is also compared in full. It
configures request member `+5D0` with kind3 and endpoint
`2.0/elite/initiative/optin`, then installs typed vtable `511F9D0`.
Its unique current paired body references the same typed table and unchanged
endpoint text at old`5247D30` → new`5247D00`; the original/current `mov edx,3`
instructions are explicitly checked. This is constructor/type evidence, not
an assumption based on neighbouring function addresses.

`Trace-GalaxyCommunityGoalCompatibility.py` writes the paired proof; the earlier
`community-goal-optin-unresolved.json` records only the initial ambiguous
body-only search and is superseded by
`community-goal-optin-compatibility.json`. `Prepare-GalaxyClientMapping.py`
checks the full bodies, direct call targets and relative call positions,
constructor kind, complete endpoint bytes and paired type/endpoint operands.
The source inventory continues to require the sender address. No source hash
or missing address rule is relaxed.

No game process, request, CG opt-in or other mutation is executed by this work.
The existing CG source is not modified. This proof establishes static version
correspondence only and does not grant runtime validation or action permission.
