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.

Two fixes hardening the redux-thunk dynamic-dispatch synthesizer, found by
validating it on real RTK repos beyond its trezor origin (uwave-web,
session-desktop, octo-call):
- Surfacing: buildFlowFromNamedSymbols filtered its named set to CALLABLE
kinds, so synthesized edges between `constant` nodes (RTK thunks are
`const X = createAsyncThunk(...)`) never entered the Flow / Dynamic-dispatch
links scan — invisible at every tier, while the kind-agnostic Relationships
section is off below 500 files. Add a `dynNamed` set (named constant/variable/
field nodes with a heuristic edge) feeding a shared collectSynthLinks into the
"## Dynamic-dispatch links" section, threaded through the named.size<2
early-out (both-endpoints-constant hit return EMPTY first) and the main path.
Main call-chain stays callable-only; the <500 budget tiers are untouched.
No-op for callable flows. Plus a generic synthEdgeNote fallback so any synth
hop reads "dynamic: <kind> @site", not a bare "[calls]".
- Precision: reduxThunkEdges resolved a dispatched name by first-match-by-kind,
so a thunk name colliding with a same-named service function linked to the
wrong node (octo-call `leaveCall`). Prefer thunk-signature const > other
const > same-file callable > first match.
Tests: new explore-synth-constant-endpoints.test.ts (surfacing on a small repo)
+ a collision case in redux-thunk-synthesizer.test.ts. Full suite green (1605).
Rationale + coverage backlog in docs/design/dispatch-synthesizer-backlog.md.
