-5b. **`culver` had been red for every one of its 13 runs since 2026-07-19**, and
-   the whole blockage was accumulated clippy lint: one `redundant_closure`, then
-   four more plus a `field_reassign_with_default`. None were real defects — but
-   because `-D warnings` fails the job at the first crate, each fix only reveals
-   the next, and nobody had walked the chain. Fixed 2026-07-25 (`1e3ea12`,
-   `b28b15f`); the fallbacks now say `DateTime::UNIX_EPOCH`, which is what the
-   surrounding comments claimed all along while the code carried a dead
-   `Utc::now()` branch.
+5b. **`culver` had never once been green** — 16 red runs from its first on
+   2026-07-19. **Green as of #17, 2026-07-25.** The whole blockage was
+   accumulated clippy lint, in a chain: `culver-core` → `culver-telephony` +
+   `culver-contacts` → `culver-matrix` → the cxx-qt app crate. `-D warnings`
+   stops at the first failing crate, so each fix only exposed the next and
+   nobody had walked it. Four commits: `1e3ea12`, `b28b15f`, `ab559bc`,
+   `8dc8553`.
+
+   None of it was a real defect, but the rot is worth recording because a
+   working pipeline would have caught each item the day it was written:
+   - three `unwrap_or_else(|| Utc::now())` fallbacks sitting under comments
+     that said "never *now*" — the dead branch contradicted its own docstring;
+     now `DateTime::UNIX_EPOCH`
+   - a `DiffMirror.account` field kept alive by an `_account()` accessor that
+     was itself dead
+   - **the app crate had never been linted at all**: four
+     `pub use qobject::X as QX` re-exports referenced nowhere (dead by
+     construction — nothing can import from a binary crate), four matching
+     unused imports, `beginInsertRows`/`endInsertRows` declared on two models
+     that never insert (`chat.rs` genuinely uses its pair, which is why clippy
+     spared it), a `pending: VecDeque<ModelUpdate>` queue documented as
+     "drained on first `apply`" that nothing drained, and an uncalled
+     `set_header`.
+
+   One `#[allow]` was used, on `handle_command`'s 8 arguments, with the reason
+   in a comment. Everything else is a real fix.
 
    The structural point outlasts the fix: **culver's CI has no packaging step.**
    It runs test, clippy and build, then stops. Green culver still ships nothing.
