- #108964: \[Bug\]: sanitize_context() is single-pass, so overlapping memory-context tags reassemble into a live fence that closes the recall block early
- PR #108965: fix(memory): sanitize recalled context to a fixed point so overlapping fence tags cannot reassemble
- PR #109086: fix(agent): make sanitize_context idempotent on overlapping tags (#108964)

These items concern a bug where single-pass sanitization of memory/context tags allows overlapping tags to reassemble into active fence markers. The work involves making sanitize_context run to a fixed point to prevent this reassembly.
