docs(tibia): persist Track A live-session login handover

[blakinio]

Summary

Persist the 2026-08-13 Track A official-Linux-client findings in blakinio/otclient so continuation does not depend on chat history.

Includes:

• explicit Track A vs Track B correction;
• successful historical login/session-recovery procedure without secret values;
• precise note that OCR was used only to locate the character row during selection;
• decoded Worldmap and native-action claim boundaries;
• downstream GameclientMessageRotateEast static leads with exact version fencing;
• owner-observed position/collision/pathing correction;
• passive nearby-action logging limitations;
• canonical synology-otclient-01 revalidation sequence.

Documentation only. No runtime mutation, secret access, Track B changes, proprietary client bytes, or owner-funded AI usage.

Validation

• Re-read the created task and report from the branch through the GitHub connector.
• Verified repository is exactly blakinio/otclient and base is main.
• Runtime E2E: NOT_APPLICABLE for this documentation-only handover; runtime facts are explicitly fenced as REVALIDATION_REQUIRED or OWNER_OBSERVED where not already repository-proven.

[blakinio]

Coordinator disposition: ACCEPT_WITH_EDITS for bounded historical evidence; supersede this stale handover PR as an active continuation source.

Accepted and preserved on coordinator PR #300:

• the historical native-Linux login/session recovery sequence, explicitly REVALIDATION_REQUIRED;
• the correction that OCR was used only to locate character-selection row geometry, not as in-world semantic evidence;
• SOCKS/WARP confinement and secret-minimization requirements;
• the distinction between structural IN_GAME proof and UI/socket correlation.

The bounded accepted extract is now durable at docs/agents/evidence/OTC-20260815-track-a-promotion-coordination/accepted-historical-login-procedure.md.

Not promoted from this PR: stale next_action sequencing, old transient runtime state, owner-observed position as authoritative state, or historical message/string offsets as current facts. Current restart/relogin/reacquisition validation belongs to Draft PR #303 and must independently rediscover fresh PID/PIE/runtime state.

This PR can therefore be closed unmerged without losing its accepted evidence.
