 - Training web API: list ongoing trainings (`GET /api/allTraining`) and interrupt a running training (`DELETE /api/killTraining`). Killing a training releases the per-model lock so the model can be retrained; interruption is best-effort for native (Wapiti/DeLFT) back-ends.
 
 ### Changed
+- Updated pdfalto to 0.6.1. Notable for GROBID: deterministic output (an uninitialised read and a use-after-free made line/block grouping depend on heap contents, so the same PDF could yield different `<TextLine>`/`<TextBlock>` structure across runs), bounded peak memory on very large or vector-heavy documents, and several text-extraction fixes. The command-line options GROBID passes are unchanged.
+- pdfalto is now given GROBID's configured temp directory (`grobid.temp`, by default `grobid-home/tmp`) through `TMPDIR`. Since 0.6.1 pdfalto streams large page DOMs to a scratch file to bound peak memory and picks its location from `TMPDIR`, falling back to `/tmp` — which is tmpfs in most containers, so spilling there leaves peak memory unchanged and risks ENOSPC.
 - Lexicon: introduced `Lexicon.builder()` to optionally pre-load chosen gazetteers *eagerly* (`.withDefaults()`, `.withJournals()`, `.withFunders()`, `.withOrganisations()`, etc.). Loading stays **lazy by default**: any gazetteer not named in the builder loads transparently on first lookup, so a `Lexicon` from any entry point is always fully functional and never throws for a missing gazetteer — `withX()` only controls *when* a gazetteer loads, not whether a lookup succeeds. `withDefaults()` eagerly loads the original constructor's set (wordforms, people, countries). `Lexicon.getInstance()` is now `@Deprecated` (prefer the builder) but its behavior is unchanged: eager wordforms/people/countries, everything else lazy.
 - Lexicon: added 4 missing ISO 3166-1 country codes (BQ, CW, SS, SX) and migrated AN (Netherlands Antilles) to its ISO 3166-3 transitional form ANHH.
 - Documentation: expanded the End-to-end evaluation guide (dedicated multi-dataset runner-script section for `run_evaluation.sh` with an options table and more invocation examples) and the Configuration reference; recorded the Hugging Face DOI (10.57967/hf/9553) for the `grobid-evaluation` dataset.
 
+### Fixed
+- Handle the exit codes pdfalto 0.6.1 introduced. Code 5 reports that the ALTO was written correctly but page streaming was disabled mid-run, so peak memory was no longer bounded; both execution paths rejected any non-zero exit and would have discarded these successful conversions. It is now a logged warning. Codes 4 (ALTO write failed) and 98 (allocation failure) are reported as `PDFALTO_CONVERSION_FAILURE` instead of falling through to `BAD_INPUT_DATA`, which blamed the PDF for a pdfalto-side failure.
+
 ### Security
 - Prevent command injection through crafted PDF file names in the non-server `pdfalto` path: the command is no longer interpolated into a `bash -c` string but passed as positional parameters and exec'd via `"$@"` (GHSA-mgxf-7mg7-qpmf).
 - Stop leaking a JVM thread per request on the `/api/modelTraining` endpoint by shutting down the per-request executor (GHSA-g2r5-4c8r-c84f).
