Makes the Mantis Telegram Desktop proof agent programmable at its trust boundaries: declarative Bot API fault rules (drop/status per method), per-request scripted mock-provider responses, observe-until predicates (post-cursor events/text, cumulative provider count), and bounded proxy-side recording of outbound Bot API requests as trusted lane facts. Adds a reusable recipe library under .github/codex/prompts/mantis-recipes/ and raises the proof agent's reasoning effort to high.
Security: the SUT container shadows proxy-control with an inaccessible tmpfs so candidate PR code sharing the mantis-sut uid cannot read or rewrite the proxy's recorded evidence; unmount is blocked by cap-drop/no-new-privileges. Proof doctrine now treats proxy-recorded Bot API facts as trusted comparison evidence and provider request logs as diagnostics.
Follow-up named in PR: move the mock OpenAI server out of the SUT container so provider request facts also become candidate-tamper-proof.
