Part of hyperhive#1898 (b): every docs subdir should have a top-level
README.md link, achieved by moving/renaming where an existing file
already fits the role.
docs/turn-loop.md already served as the hub + index for the three
sub-pages under turn-loop/ (claude-invocation.md, config.md, mcp.md),
so it moves wholesale rather than leaving a redundant top-level
pointer stub. Fixes every inbound/relative link across the repo
(top-level README.md, CLAUDE.md, docs/persistence.md,
docs/tools/scheduling.md, the sub-pages own back-link, hive-agent
README + doc comments, hive-agent/Cargo.toml, .prettierignore per-file
exemption entry) - grepped the whole tree for both turn-loop.md and
turn-loop/ to find every reference rather than trusting a partial
list.
nix fmt clean, cargo check -p hive-agent clean.
The edit_schedule MCP tool accepts interval_seconds as Option<u64>
(positive values only), mapping None→leave-alone and Some(v)→set.
The handler wraps this as .map(Some) before dispatching, so there
is no way to express Some(None) = clear via the agent surface.
The old doc said 'Clearing interval_seconds to null flips
recurring → one-shot' which is only true for the dashboard
PATCH endpoint (which uses the full double-Option form).
Corrected: interval_seconds is positive-only via the MCP tool;
toggling recurring→one-shot is operator-only via the dashboard.
