 - sl-viewer corpus_cta constants property surface (WBS-6.2 #453): `crates/sl-viewer/tests/properties_viewer_corpus_cta.rs` adds 9 proptest properties — `QUICKSTART_URL` is non-empty, uses HTTPS, ends in `QUICKSTART.md`, and points at the canonical `KooshaPari/SessionLedger` repo. `QUICKSTART_CORPUS_DOC` is the documented `docs/guides/quick-start/QUICKSTART.md` repo path, and its basename matches the URL basename. `CORPUS_PICKER_INPUT_ID` and `FORGE_DB_HINT_STORAGE_KEY` are non-empty, kebab-case ASCII, and distinct.
 
+- sl-viewer theme property surface (WBS-6.2 #454): `crates/sl-viewer/tests/properties_viewer_theme.rs` adds 28 proptest properties — `Theme::default()` is `System`, `Theme` JSON round-trips for every variant, and the serialised form uses lowercase. `ThemeColors::dark` / `ThemeColors::light` each expose 9 fields (bg / surface / text / accent / secondary / border / focus / danger / muted) that all match the documented `lab_coat::*` constants; every field is non-empty; `focus == accent` for both palettes. `for_theme(Dark) == dark()`, `for_theme(Light) == light()`, `for_theme(System) == dark()` (desktop fallback).
+
+- sl-viewer settings property surface (WBS-6.2 #454): `crates/sl-viewer/tests/properties_viewer_settings.rs` adds 21 proptest properties — `DefaultTab::default()` is `Bundles`; `DefaultTab::ALL` covers every variant, has length 9, and every `tab_id()` / `value_attr()` is unique, kebab-case ASCII, and `tab_id()` is the `tab-` prefix of `value_attr()`. `Settings::default()` is `{theme: System, default_tab: Bundles}`; JSON round-trip preserves the struct; serialised `theme` is lowercase and `default_tab` is kebab-case; `save_to_path` / `load_from_path` round-trip equal configs; missing/corrupt files fall back to `default()`; missing parent directories are created. `resolve_settings_dir` honours non-empty overrides, falls through on empty overrides, picks the documented macOS / Windows / Linux paths conditionally.
+
+- sl-viewer help_overlay shortcut property surface (WBS-6.2 #455): `crates/sl-viewer/tests/properties_viewer_help_overlay.rs` adds 13 proptest properties — `SHORTCUTS` is non-empty; every shortcut has a non-empty `keys` / `scope` / `action`; every `action` is descriptive (has at least one ASCII letter) and human-readable (no `ERR_` / `error code` leaks); every `(keys, scope)` pair is unique so the rendered table does not collide on its React key; the `?` help toggle, `Escape` close, and `Cmd+K / Ctrl+K` command palette shortcuts are present; every `scope` is one of the documented panel scopes; every `keys` is non-blank.
+
+- sl-viewer settings_tab HealthStatus property surface (WBS-6.2 #456): `crates/sl-viewer/tests/properties_viewer_settings_tab.rs` adds 11 proptest properties — `HealthStatus::Unknown.label()` is `"checking"`, `Healthy` is `"healthy"`, `Unreachable` is `"unreachable"`; every variant's label is non-empty, distinct across variants, single-line, and lowercase ASCII; `label()` is deterministic across calls. `THEME_RADIO_GROUP_ID` is non-empty, kebab-case ASCII, and distinct from `FORGE_DB_HINT_STORAGE_KEY`.
+
 - Commit signing header scan (C04 L34): `commit-signing-check.ps1` reads bounded commit headers via line-scanner (no unbounded `git cat-file` buffers or `(?ms)` regex); `-SelfCheck` + `tests/commit_signing_check.rs`.
 
 - Loom permutation CI timeout (P0 stability): split blocking `loom-permutation.yml` into core + per-daemon `loom_model` jobs with `LOOM_MAX_PREEMPTIONS` on broadcast/pipeline/shutdown; mirror in soft `loom-smoke.yml` so Wave-40 tokio-shaped daemon graph tests no longer exceed single-job ceilings.

+//! Property evidence for sl-viewer's `help_overlay::SHORTCUTS` constant.
+//!
+//! The shortcut table is rendered into the `?` keyboard help overlay and
+//! mirrors `docs/viewer-hotkeys.md`. If a row is added, removed, or
+//! labels drift, the in-viewer help silently desyncs from the docs
+//! page. Every visible property is pinned here.
+//!
+//! `help_overlay::SHORTCUTS` invariants:
+//!  * Non-empty.
+//!  * Every shortcut has a non-empty `keys` / `scope` / `action`.
+//!  * Every `keys` string is non-empty.
+//!  * Every `scope` string is non-empty.
+//!  * Every `action` string is non-empty.
+//!  * Every `action` contains at least one ASCII letter (descriptive).
+//!  * Every `action` is human-readable (no `ERR_` / `error code` leaks).
+//!  * Duplicate (keys, scope) pairs are not allowed (the rendered
+//!    table uses these as React keys, so duplicates would collide).
+//!  * The `?` help toggle and `Escape` close are present.
+//!  * The Cmd+K / Ctrl+K command palette is present.
+//!  * Sorted by `keys` is not required (order matters for the rendered
+//!    table), but uniqueness is.
