+//   (1) The host never parses them as turn boundaries; a model emitting
+//       them does NOT cause the original #3247 security failure mode.
+//   (2) They collide with legitimate output far more often than the
+//       Markdown family (e.g., "User: bob@example.com", form labels,
+//       JSDoc lines). With kill-on-detection wired in server.ts
+//       (`abortForRoleMarker`), a false positive aborts the whole run
+//       — a much more expensive failure than a stray unflagged
+//       `User:` line in the chat scrollback.
+// If a host frontend ever starts parsing chat-style markers as
+// boundaries, narrow the additions to that frontend's specific
+// path rather than the shared regex.
+//
+// Three deliberate refinements vs. a naive `## role` match:
+//
+// 1. CASE-SENSITIVE. The chat host's turn-boundary delimiter is
+//    lowercase (`## user` / `## assistant` / `## system` — see
+//    `buildDaemonTranscript` in apps/web/src/providers/daemon.ts), and
+//    the `## CRITICAL` system-prompt block forbids only the lowercase
+//    forms. Title-Case Markdown headings like `## User Guide`,
+//    `## System Architecture`, `## Assistant settings` are LEGITIMATE
+//    content (LLMs emit these constantly in technical writing) and
+//    must not contaminate. Matching with `/i` would deterministically
+//    abort any run that produced such a heading — exactly the
+//    "false positive aborts the whole run" cost the docblock cites
+//    as the reason to keep the regex narrow.
+//    (See PR #3303 review r3324151877.)
+//
+// 2. POSITIVE LOOKAHEAD `(?=[^a-z])`. Without it, `## userland`,
+//    `## userspace`, `## users guide`, `## systemd`, `## assistance`
+//    all match via prefix in the alternation. The positive lookahead
+//    requires the character after the role keyword to exist AND to NOT
+//    be a lowercase letter:
+//      - `## user\n…`     → match (newline is not lowercase)
+//      - `## assistantR…` → match (R is uppercase; the glued-form
+//                           attack pattern still gets caught)
+//      - `## assistant.`  → match (. is not a letter)
+//      - `## users guide` → no match (s is lowercase letter)
+//      - `## userland`    → no match (l is lowercase letter)
+//    Why POSITIVE `[^a-z]` rather than NEGATIVE `(?![a-z])`: the
+//    negative form is satisfied at end-of-string, which in a streaming
+//    context means "we have just received `## user` but don't know
+//    what comes next yet". A negative lookahead would fire prematurely
+//    if the rest of the role-keyword landed in a later chunk (e.g.
+//    the model emits `## user` then `land` arrives). The positive
+//    form requires an actual non-lowercase character to be present,
+//    so detection waits one more chunk in that edge case — a
+//    one-character latency traded for correctness.
+//
+// 3. `[ \t]` instead of `\s` for inner whitespace. `\s` matches
+//    newlines, which would let oddities like `##\nuser` match across
+//    lines. Markdown role markers are always single-line by

+ * `m.content` by `buildDaemonTranscript`, so it cannot become a
