`check-doc-refs.sh` resolves the PATH half of a `docs/x.md::Section`
pointer and stops there. The section half rots the same way, and more
quietly: the file still exists, so every path-shaped check stays green
while the pointer names nothing.
Eighteen sites, five distinct pointers, each retargeted at a heading
verified to exist rather than at the nearest plausible one:
docs/web-ui.md::Container row
-> docs/web-ui/dashboard.md::Container row
docs/web-ui.md::Shared terminal pane
-> docs/web-ui/shape.md::Shared terminal pane
Both sections moved out when docs/web-ui.md became a two-heading
index. The path still resolves, which is exactly why nothing
caught them.
approvals.md::Helper events to the manager
-> approvals.md::Helper events to the submitting agent
Renamed with the manager special-casing removal; the pointer kept
the old vocabulary.
approvals.md::Migration from the pre-tag
-> approvals.md::Startup migrations (older hosts)
Same content, including the HIVE_SKIP_META_MIGRATION kill switch
the citing comment names.
agent-hierarchy.md::Current state
-> ::Where the tree lives (topology.rs, container_view.rs)
-> ::Reparenting (topology.rs's set_parent, host-sock)
Split by what each site actually asks for rather than repointed
uniformly: two want the format and the source-of-truth rule, two
want the reparenting validation.
Three known-dead pointers are deliberately left alone:
* `docs/integrations/forge.md::Sources` sits on a line PR #3927
rewrites; fixing it here would conflict for no gain.
* `docs/web-ui/shape.md::One unified channel` names real text that is
bold inline rather than a heading — which of those counts as
resolvable is the open question on #3922.
* `persistence.md::Harness state files` should point at a heading
whose own text contains backticks, and the backticked-pointer form
cannot nest them. That is a limit of the convention, not a typo.
Comments only; no behaviour change. Refs #3922.
