 ## [Unreleased]
 
+### Fixed
+
+- **`freehire-search` fractional numeric flags no longer silently change the query** (#373) -
+  `parseIntFlag` used bare `parseInt`, so a fractional value was truncated instead of
+  rejected: `--jobage 0.5` became `0`, failed the `jobage > 0` guard, and the
+  `posted_within_days` freshness filter was silently omitted from the outbound request
+  while the CLI exited 0 - on a default-ON `/scrape` portal, exactly the
+  discarded-filter failure the CLI's own `UNKNOWN_FLAG` guard documents. Numeric flags
+  (`--jobage`/`--page`/`--limit`) now accept whole numbers >= 1 only, mirroring the
+  Danish CLIs' `z.coerce.number().int().min(1)` contract, and reject everything else
+  with the stderr-JSON `BAD_ARG` error. The sibling of #371 (`linkedin-search`), which
+  remains with its reporter. Pinned by five new cases in `cli-flag-validation.test.ts`,
+  each verified to fail on the unfixed code.
+
 ### Added
 
 - **pypdf ATS text-layer fallback** - `/apply` Step 5d and `tools/verify_pdf.py` extract the CV PDF text layer with **pypdf** first (BSD, `pip install pypdf`) so Windows machines without Poppler still get a mechanical parseability check. Poppler `pdftotext -layout -enc UTF-8` remains the fallback; if both are missing the check still degrades to a visual keyword review. No extra cache or installer. `05-cv-templates.md` `framework_version` 1.4.2 → 1.4.3.
