`scan_active_content` called directly and `okf.link_graph` were the two surfaces
still reading attacker-supplied text with no cap — the first reached by an
adapter that wants the active-content classes alone, the second running a
`findall` over every body in a bundle. Both are detection-shaped, so they
truncate and flag rather than raise the way the transform surfaces do: what a
detector shortens is its own coverage, not the caller's content.
Truncation is only honest if it is visible, so neither goes quiet: the scanner
emits `active:oversize-input` (LLM10), and `link_graph` records
`(from_id, body_length)` in `LinkGraphResult.truncated` — the field that lets a
caller tell "no links past here" from "no links read past here".
Reached through `scan_output`, the text is already under that surface's cap and
`max_scan_chars` is now passed down, so the flag is raised once, there.
