MCP tool results used Markdown ATX headings (##/###/####) for section
headers — the status summary, each search hit, every file section in an
exploration — which Markdown-rendering clients (e.g. the Claude Code
VSCode extension) blow up to H1–H4 font size, filling the transcript with
oversized lines (worst on search/explore, where the noise scales with
result count). Swap them all for bold labels, which render at body size
while keeping the same structure. CLI/TTY output (ContextBuilder) is
unchanged — the issue notes it's fine.
The format is parse-coupled, so kept in sync:
- The explore truncation boundary and the offload chunker
(reasoning/reasoner.ts) both key off the per-file header, now a unique
`**`-prefixed marker emitted via a shared fileSectionHeader() helper.
- Updated the offload strip regexes and switched the opt-in report-style
prompt off ATX headings (same client, same rendering issue).
- Updated test helpers (sectionFor, sourcedFiles, the callers
section-boundary scan) that scanned the old markers.

codegraph_explore's file sort is primarily driven by Random-Walk-with-Restart
graph-centrality mass, seeded from the query's text matches. In a cross-layer
monorepo (an API server alongside a much larger, internally dense frontend that
mirrors the same domain words), that mass skews to the bigger layer — so a
backend service/handler that genuinely matches several query terms, even when
it's the #1 search hit, sorts below hits=0 frontend files and gets truncated out
of the response, and the agent reads it back.
Add a corroboration tier above the graph signal: a file that is BOTH an
entry/central file AND matched by >=2 distinct query terms is kept in. The
entry/central guard prevents an incidental multi-term file (a type/util file
that isn't the flow) from displacing a graph-central answer file — a blunt
hits-only tier regressed that case. Single-layer repos are unaffected. Gated by
CODEGRAPH_RANK_NO_MULTITERM=1.
