 - sl-viewer timeline property surface (WBS-6.2 #433): `crates/sl-viewer/tests/properties_viewer_timeline.rs` adds 16 proptest properties — `group_by_day` partitions every entry into exactly one group with no losses, orders groups chronologically, and labels empty-day groups `"(unknown date)"`. `normalize_widths` produces one width per input entry, all in `[MIN_PX, MAX_PX]`, with all-zero inputs collapsing to MIN_PX and the max-tokened entry rendering at MAX_PX. `model_hue` is deterministic and in `[0, 359]`; `model_color` matches `hsl(<hue>, 60%, 55%)`. `TimelineEntry::from_bundle` properties pin: `day` is the leading 10 chars of `created_at` (else empty), `goal` falls back to `"(no goal)"`, `model` falls back to `"unknown"`, `source_id` carries through, `message_count` / `has_acceptance` / `has_contract` match the input, and `token_count` falls back to 0 when no Intent slice carries a numeric `user_turn_count`.
 
+- sl-viewer bundle_list + detail_pane property surface (WBS-6.2 #436): `crates/sl-viewer/tests/properties_viewer_bundle_detail.rs` adds 11 proptest properties — `bundle_list::summarize` carries `source_id` through unchanged, matches input `bundle_count`, reflects kind presence (`has_acceptance`/`has_contract`), falls back to `"(no goal)"` when no Intent slice carries a string `goal`, and is deterministic. `detail_pane::extract_detail` carries `source_id` through unchanged, always emits `IntentState::Extracted`, matches `bundle.total_token_estimate()` for the token total, mirrors `Option<String>` fields (`intent_goal`, `context_cwd`, `context_title`) exactly, and is deterministic.

 - Wave-44 plan landed: `WAVE44_SCOPE.md` + `docs/ops/WAVE44_PERT.md` enumerate 6 close-out lanes (3 machine, 3 human-gated) for the 6 unpaid residuals from Wave-43 (396/402 → 402/402 target). Theme: stack-stability closure + i18n migration + eval coverage + supply-chain signing.
 - Wave-44 reaudit (Wave-44-D): `audit/SCORECARD.md` refresh at commit `13c974f7` (machine-w44-reaudit); `docs/ops/TRACEABILITY.json` overall_audit wave=Wave-44 commit=13c974f7 (conservative hold at 396/402); `docs/ops/GAP_QA_MATRIX.md` C00 + C08 + PLAN-W8-B rows reflect Wave-44 closure (#368 W44-B6 corpus / #372 W44-B1 loom / #373 PERT correction). 2 of 3 machine lanes shipped 2026-07-24; remaining 6 raw pts across C04 L36 / C08 L76 / C11 L110.

+//! Property evidence for sl-viewer's `bundle_list::summarize` and
+//! `detail_pane::extract_detail` reductions.
+//!
+//! Integration tests. The unit tests in those modules pin specific
+//! values; these properties pin invariants over the full shape of
+//! inputs the helpers can receive.
+//!
+//! `bundle_list::summarize` invariants:
+//!  * `source_id` is carried through unchanged.
+//!  * `intent_goal` is the first Intent slice's `body["goal"]` string,
+//!    or `"(no goal)"` when no Intent slice is present or none carries
+//!    a string `goal`.
+//!  * `bundle_count` equals the input slice count.
+//!  * `has_acceptance` / `has_contract` reflect presence of those
+//!    kinds in the input bundle list.
+//!
+//! `detail_pane::extract_detail` invariants:
+//!  * `source_id` is carried through unchanged.
+//!  * `intent_goal` is the same fallback contract as `summarize`.
+//!  * `intent_state` is always `IntentState::Extracted` (the only state
+//!    the reduction can produce, given the heuristic extractors).
+//!  * `total_token_estimate` matches `bundle.total_token_estimate()`
+//!    (call through to the same underlying reduction).
+//!  * `acceptance_signals` / `constraints` are empty when the Intent
+//!    slice is absent; otherwise they hold the string members of the
+//!    matching JSON array, in input order, filtering out non-strings.
+//!
+//! proptest is added to `sl-viewer/[dev-dependencies]` (mirroring the
+//! workspace root); see PR #425 for the initial wiring.
