Phase 26 slice CF.2 (docs/COUNTERFACTUAL_DESIGN.md §3; resolved §7:
inline per-claim expander) — completes the approved Phase-26 ladder.
- shared/case-counterfactual.js traceLines(delta, {claimsById}) — the
pure plain-list source the DOM projects 1:1: every line a count with
its derivation on the face (knot dissolve/split/shrink, only-support
losses with claim texts, attestation origin deltas with surviving
origins, falling propositions with chain lengths, entity/timeline
losses, hypothesis-edge removals or role-flips). Negate wording says
flips/rests-on and recomputes no verdict; the honest zero states
that nothing rests on the claim.
- shared/hypothesis-map.js collectHypothesisEdgeJoins — one read of
both models, canonicalized refs + labels, the CF.1 hypothesisEdges
join input.
- portal/trace-block.js mountTraceExpander — a native details element
per claim row in the evidence block; computes LAZILY on first open
over the already-collected shared data envelope; If removed /
If negated mode toggle; explainer states "measured over the local
graph. Not a probability of anything."
- evidence-block accepts {data, hypothesisEdges}; case-view collects
the joins once beside the shared assembly and passes both through.
- Tests: traceLines content for both modes, the honest zero, and the
§4 copy guard — no likelihood/strength/percent phrasing in any line
or derivation, either mode, across four claims.

The manual checklist for the H.1–H.4 / CF.1–CF.2 surfaces: authoring idempotency, seed promotion, crux badges, verdict-chip context, the no-scoreboard read, the gated LLM suggestion with its disclosures and the unopposed check, and the trace expander's remove/negate/zero paths.

Summary
Phase-26 slice CF.2 — the final slice of the approved ladder. Stacked on #174 (→ #173 → #172 → #171 → #170 → #169); merge in order.
Each claim row in the case view's Evidence block gains a Trace dependencies expander (a native
<details>, computed lazily on first open over the already-collected shared data envelope — no second collection pass). Inside:traceClaimDependencies(CF.1),traceLines— every line a count with its derivation on the face: "A contradiction knot of 3: it dissolves — edges: link_…", "Leaves 1 claim with no remaining support", "Proposition …: attestation origins 2→1 (demonstrably independent 1→1)", "Hypothesis 'Zoonotic': loses 1 supporting and 0 undermining attachments",collectHypothesisEdgeJoins(one read, canonicalized) feeds the hypothesis-map joins into the delta.Guard
The §4 copy guard runs
traceLinesfor both modes across four differently-shaped claims and bans likelihood/strength/percent phrasing in every line and derivation string.Tests: 1,784 green (4 new) · build clean · lint 0 errors.
