Audit-only correction for AUDIT-012. No production keybinding or input behavior is changed.

Scope

• FarmHelperSettingsController.java is restored exactly to the fixed base controller blob 742a570ccc47bba19163d0d02ae1ec27d0ad614c.
• Controller tests exercise the real 26.1.2 InputConstants/KeyMapping boundary and a test-only tick seam: KEYSYM/344 versus SCANCODE/54, right/left Shift identity, click queue consumption, one-screen opening, held/repeat suppression, existing-screen and unrelated-key guards, and remapped InputConstants.KEY_F6.
• AUDIT-012 records P0-06 as PLAYER_TOOL_BLOCK/INCONCLUSIVE. It records upstream default F, the undocumented/unreviewed modern Right Shift difference, and offhand conflict only as an unproven hypothesis.

Evidence

• The current-master event-to-KeyMapping harness consumed KeyEvent(344, 54, 0) as KEYSYM/344 and did not consume KeyEvent(-1, 54, 0) for a KEYSYM/344 mapping.
• The supplied R4 Computer Use Shift_R action did not establish which event identity reached Minecraft, so no product root cause or fix is claimed.
• Supplied P0-04 /fh open and P0-05 /farmhelper open paths passed; Builder performed no GUI, Computer Use, input, or Player rerun.

Local verification

• 686 tests passed with 0 failures and 0 errors.
• Focused settings/screen/command suite, check, verifyDependencyProvenance, and validateAccessWidener (NO-SOURCE) passed.
• Two clean builds produced identical FarmHelper-26.1.2.jar SHA-256 42A79DC679FBD843FAAF40B601F1A7A5671C6BC1D452DF9E5913ED406C214C25, 890472 bytes.
• Implementation candidate: 4ecbd39, tree 10c44db8f12a63d6a7a874b5ff70d7b508e802f7.
• Final publication head: 322b40c. Exact-head PR CI run 32788620622 passed Linux / test, Linux / build, Windows / test, and Windows / build; matching push run 32788617000 also passed.
