Swap the trust-fence marker shape from <tag_nonce>...</tag_nonce> to [start tag_nonce]...[end tag_nonce] for both the operator fold (system-reminder) and the output-guard judge (tool_output). Angle-bracket markup pushed some local models out of distribution and toward emitting their own turn-structure tokens: chat templates built around rigid <...>-style structural tokens derail once a few folded reminders accumulate. The start/end keywords carry no slash (no </ or [/ closing-tag shape) and read as ordinary text. Single-source the shape in fence.py (_OPEN_KW/_CLOSE_KW + detection_pattern) so wrap, neutralize, the forgery/leak detector, and both trust declarations track one definition. The nonce still rides both boundaries (unforgeable close); the leak-vs-forgery split and the forge-in / break-out defang are preserved. The fold is wire-only, so there is no migration; the legacy persisted-envelope readers keep the old shape. Add regression tests pinning each trust declaration to fence.wrap's emission so a future keyword change fails loudly instead of silently desyncing the anchors.
