-### CLI — project config file (`depradar.toml`)
-
-- **What:** Adds `src/config.rs` with a `ProjectConfig` struct that `depradar
-  scan` loads from `depradar.toml` in the working directory. The file supports
-  four keys:
-  - `fail_on` — severity threshold for a non-zero exit code
-    (`low`/`medium`/`high`/`critical`/`none`; default `high`).
-  - `format` — output format (`text`/`json`; default `text`).
-  - `exclude` — array of glob patterns for lockfile paths to skip.
-  - `ecosystems` — array of ecosystems to restrict scanning to (`npm`,
-    `pypi`, `cargo`, `go`, `maven`, `rubygems`, `packagist`; default: all).
-
-  Loading is strictly opt-in: if no `depradar.toml` exists the built-in
-  defaults are unchanged. An existing but malformed file exits with code 2 and
-  a clear error pointing to the file. Unknown keys are rejected.
-
-  Precedence is: **built-in defaults ← `depradar.toml` ← CLI flags**. CLI
-  flags always win, so existing scripts and one-off commands are unaffected.
-  The `--fail-on`, `--exclude`, and `--ecosystem` flags are new on the CLI
-  (previously undocumented/unimplemented), and `--format` is now optional
-  rather than defaulting on the struct level, giving the file a chance to
-  provide the default.
-
-- **Tests:**
-  - Unit tests in `src/config.rs`: `FailOn` ordering, round-trip
-    `FromStr`/`Display` for all three enums, full-config TOML parse,
-    empty-file parse, unknown-key rejection, invalid enum value rejection,
-    `load_project_config` returning `None` when absent, loading from a
-    directory, and error on malformed TOML.
-  - Integration tests in `tests/cli.rs`: config file format setting used
-    when no flag is passed; CLI `--format` overrides the file; `fail_on =
-    "none"` exits 0 with findings; `--fail-on high` overrides `fail_on =
-    "none"` in the file; `exclude` pattern skips a path; CLI `--exclude`
-    overrides the file; no config file uses defaults; invalid config exits 2
-    with a message mentioning `depradar.toml`.
-  - `cargo fmt`, `cargo clippy -- -D warnings`, and `cargo test --workspace`
-    all pass.
-- **Docs:** README updated with a `depradar.toml` section, a key reference
-  table, and an updated CLI options table reflecting the newly implemented
-  flags.

-### behavioral — safe npm tarball download and unpack
-
-- **What:** Adds `src/behavioral/tarball.rs`. `download_npm_dist` downloads
-  `dist.tarball` through the shared polite HTTP client, caps the body at
-  50 MB, and verifies `dist.integrity` as a SHA-512 SRI digest before
-  returning any bytes (`verify_integrity` accepts several SRI tokens and
-  requires at least one matching `sha512-` value). `unpack_tarball`
-  decompresses a gzipped npm tarball into memory, never writing a
-  path taken from the archive and never executing anything. `UnpackLimits`
-  caps total unpacked bytes (50 MB), per-file bytes, entry count (10,000)
-  and path length (1 KB); absolute paths, `..`, backslashes, drive prefixes,
-  NULs, non-UTF-8 paths, duplicate paths, symlinks, hard links and all other
-  non-file/non-directory entry types are rejected. The npm `package/` prefix
-  is stripped only when every entry is under it. Returns sorted
-  `PackageFile { path, data }` values.
-- **Tests:** crafted tar.gz archives for path traversal, absolute paths,
-  Windows-style paths, symlinks, hard links, size bombs, total-size caps,
-  file-count caps, duplicates, non-UTF-8/overlong paths and corrupt gzip;
-  SHA-512 verification (match, tamper, missing, malformed, multi-token) and
-  mocked download size/integrity checks.

-### behavioral — npm install-script detector
-
-- **What:** Adds `src/behavioral/scripts.rs`.
-  `install_scripts(package_json) -> Vec<(String, String)>` parses
-  `package.json` and returns `preinstall`, `install`, `postinstall` and
-  `prepare` commands in lifecycle order; invalid JSON, unrelated scripts and
-  non-string values are ignored. `InstallScript::finding` wraps each one as a
-  medium-severity `BehavioralFinding` on `package.json`, and
-  `install_script_findings` returns them all. Nothing is executed.
-- **Tests:** no scripts, one script, all four hooks (with unrelated entries
-  mixed in), non-string values, and the finding message/severity.
-- **By:** ushpraise
-- **Closes:** #99
-- **Status:** In review.
-
-### behavioral — obfuscated JavaScript heuristics
-
-- **What:** Adds `src/behavioral/obfuscation.rs`. `score_javascript` scores a
-  file on base64 runs of 200+ characters (3 points), hex runs of 200+
-  characters (4), `eval(` (2), `new Function(` (3), `atob(` (2),
-  high-entropy 128+ character string literals (2 each, max 4) and source
-  lines over 2,000 characters (1). `OBFUSCATION_THRESHOLD` is 4, so a
-  minified bundle's single long-line point is not enough; scores of 8+ are
-  high severity, 4–7 medium. Markers are counted only in code, with comments
-  and string contents masked. `scan_obfuscation` emits the finding and
-  `scan_tree` walks `.js`/`.mjs`/`.cjs` files (5 MB per-file cap).
-- **Tests:** a minified-but-benign file is not flagged; an `atob` + base64 +
-  `eval` sample is flagged high; hex blobs, short blobs, markers in
-  strings/comments, lookalike identifiers, long-line-only files and tree
-  scanning.
-- **By:** ushpraise
-- **Closes:** #101
-- **Status:** In review.
-
-### behavioral — network and credential access in install scripts
-
-- **What:** Adds `src/behavioral/network.rs`. `scan_script` line-scans a
-  command or invoked script for `curl`/`wget` piped to
-  `sh`/`bash`/`zsh`/`dash`/`fish` (including `sh -c "$(curl ...)"`; high),
-  HTTP(S) requests to raw IPv4 literals (medium), and reads of `NPM_TOKEN`,
-  `AWS_*`, `GITHUB_TOKEN`/`GH_TOKEN`, `~/.ssh` and `~/.npmrc` (high).
-  Findings include a line number and a snippet truncated to 80 characters.
-  `scan_install_scripts` labels findings with the package.json hook, and
-  `scan_package` follows local script files named by lifecycle commands
-  (`node scripts/install.js`, `sh ./setup.sh`), refusing absolute or `..`
-  paths.
-- **Tests:** one per pattern (curl pipe, wget pipe, raw-IP request, npm/AWS/
-  GitHub tokens, SSH/npmrc access), a benign build script that must not flag,
-  snippet truncation, and following invoked files without escaping the
-  package root.

+### CLI — progress bar for OSV vulnerability checks
+
+- **What:** Adds a progress bar on stderr when checking packages against the
+  OSV API. Uses `indicatif` (already in `Cargo.toml`) to show
+  `Checking for vulnerabilities [###>---] 42/100 packages` during the
+  advisories stage in [`pipeline.rs`](src/pipeline.rs). The bar appears only
+  when stderr is a TTY and not in `--quiet` mode (`ScanOptions::show_progress`).
+  Non-TTY stderr (pipes, CI) sees no progress output. The bar clears itself
+  on completion so it doesn't clutter the final report.
+- **Tests:** Manual verification — progress appears when running
+  `depradar scan` on a lockfile with many dependencies, and disappears with
+  `--quiet` or when piped.
+- **By:** coderolisa
