 ## [0.16.0] - 2026-10-08
 
+### Added
+
+- **Rule-scoped inline suppression with `cora-ignore:`.** A source comment such as `// cora-ignore: Hardcoded password or secret in variable` (also `#`, `--`, `/* */`, `<!-- -->`; comma-separated rules) suppresses findings with that exact title (case-insensitive) on the same line, or on the next line when the marker line holds only a comment. Applies to both static-scanner and LLM findings; other rules and other lines stay visible, and a bare `cora-ignore` without rules suppresses nothing. Coexists with `ignore.rules` / `ignore.files` (#554).
+
 ### Security
 
 - **Project `.cora.yaml` can no longer redirect your API key.** `provider.base_url` from a discovered project config is ignored unless `CORA_TRUST_PROJECT_CONFIG=1`; `base_url` must be `https` (plain `http` only for loopback); LLM error bodies echoed to the terminal are length-capped (#563).

+## Inline Suppression (`cora-ignore`)
+
+`ignore.rules` hides a finding title across the whole project. To suppress one finding at one location, put a marker in a source comment:
+
+```ts
+const bytesPerToken = 4; // cora-ignore: Hardcoded password or secret in variable
+
+// cora-ignore: Rule A, Rule B   (comment-only line: applies to the next line)
+const next = compute();
+```
+
+- Syntax: `cora-ignore: <rule>[, <rule>...]`, matched as a substring of the line, so it works after `//`, `#`, `--`, inside `/* */` or `<!-- -->`, etc. The marker is case-insensitive.
+- `<rule>` is the finding **title**, matched exactly and case-insensitively (not a substring, unlike `ignore.rules`).
+- Scope: the same line; plus the next line when the marker line contains only a comment.
+- A bare `cora-ignore` (no `:` or empty rule list) suppresses nothing, so every suppression names its rule.
+- Applies to both deterministic scanner and LLM findings, in `cora review`. Other rules on the same line and the rest of the project stay visible. Works alongside `ignore.rules` and `ignore.files`.
+- Markers are read from the diff (added and context lines); a marker outside the diff's context window is not seen.
+
 ## Ignore Files
 
 Exclude files or directories from **all** cora operations — review, scan, and indexing. This is the broadest exclusion mechanism.

+//! Rule-scoped inline suppression of findings (#554).
+//!
+//! A source comment containing `cora-ignore: <rule>[, <rule>...]` suppresses
+//! findings whose title equals one of the listed rules (case-insensitive,
+//! trimmed — the same identity `ignore.rules` uses for titles, but exact match
+//! rather than substring so a marker cannot hide more than it names).
+//!
+//! * The marker applies to the line it is on, and, when the line contains only
+//!   a comment (nothing but the comment syntax before the marker), also to the
+//!   next line.
+//! * The marker is matched as the substring `cora-ignore:` anywhere in a line,
+//!   so it works after `//`, `#`, `--`, `/* */`, `<!-- -->`, and so on.
+//! * A bare `cora-ignore` with no `:` and rule list never suppresses anything.
+//!
+//! One filter ([`apply`]) is applied to the merged deterministic + LLM findings.
+//! It reads the post-change lines present in the parsed diff (added and
+//! context lines), so no file I/O is needed. A marker that is not visible in
+//! the diff (more than the context window away from the finding) is not seen.
