Follow-up to #12: the Build & Test job surfaced a compile error in the round-2 log_vacuum edit — "log_dir must not contain ..".into() against CapabilityResult::failure's impl Into<String> parameter leaves the target type uninferable (E0283). Pass the &str directly. One line, no semantic change.

Diff is pure rustfmt reflow plus one real change.

The only semantic edit is sentinel-capabilities/src/filesystem.rs:265: dropping .into() from CapabilityResult::failure("'log_dir' must not contain '..'", false). Per the base commit message (88115df), failure takes impl Into<String>, so a &'static str argument is accepted directly and produces the identical String — behaviour-neutral, and it removes the inference ambiguity. Nothing else in the hunk changes the control flow: the else arm still returns early before log_dir is rebound or older_than_days is unwrapped.

Everything else is whitespace-only line wrapping with identical token streams:

• filesystem.rs:563-567 — same normalise_components(...).unwrap_or_default().starts_with(&prefix) assertion, still negated.
• sentinel-exec/src/sandbox.rs:818-820 — array literal reflowed; both ("jt", i+1+f.jt) and ("jf", i+1+f.jf) tuples preserved, so the bounds assertion still covers both branch targets.
• sandbox.rs:830-848 — assert!(jumps >= 5, ...) and the three assert_eq! target checks keep their operands and messages verbatim.

No new checks are introduced, so there's no always-pass surface to hunt; the existing assertions retain their failing conditions (jumps >= 5 would still fail on a filter with no jump chain, and the t(..) equalities are compared against hard-coded indices, not recomputed from the same source).

One note, not a finding: I can't verify from the diff that cargo fmt --check now passes — the claim is that this is the formatting fix, and the reflow is consistent with rustfmt's default max_width = 100, but that's unverified here.
