Inline comments:
In `@databusclient/api/delete.py`:
- Around line 153-154: Update ManifestContext.summary() and the manifest writer
output to recognize the "dry_run" status alongside "success" and "failed",
ensuring completed dry runs are counted explicitly rather than left
unclassified.
In `@databusclient/filehandling/format.py`:
- Around line 524-533: Update the same-format branch in the format conversion
handler to create the parent directory of output_file before shutil.copy2 runs,
matching the directory setup performed by each handler’s write() method while
preserving the existing no-copy behavior when input_file equals output_file.
In `@databusclient/filehandling/mapping.py`:
- Around line 283-289: Update the CSV serialization around the row-building
logic and convert_csv_to_rdf so literal values containing “|” round-trip
losslessly: escape the separator when joining values, split only on unescaped
separators during parsing, and unescape values before creating triples. Keep the
existing behavior for values without the separator.
In `@databusclient/manifest/replay.py`:
- Around line 73-77: Update the replay manifest parameter handling around
auth_url and __get_vault_access__ so replayParams.authurl cannot control the
Vault token endpoint; always use the trusted default, or accept an override only
after validating it against an explicit allowlist. Preserve the existing
client_id behavior and ensure the token request uses the validated endpoint.
In `@databusclient/manifest/summary.py`:
- Line 52: Update format_summary to safely handle non-dict values for
dcterms:issued, dbus:executionResult, and dataid:distribution before accessing
nested fields such as `@value`; preserve the existing summary output for valid
object-shaped values and ensure malformed user-supplied manifests do not raise
AttributeError.
In `@databusclient/manifest/writer.py`:
- Line 147: Update the manifest-writing flow around _resolve_available_path and
final_path to reserve the output path atomically using exclusive file creation
rather than "w". Retry with the next available suffix when creation reports that
the path already exists, and write the manifest only after successfully
acquiring the file handle.
In `@databusclient/workflow/engine.py`:
- Line 164: Update _run_with_retry around step.run so deploy operations cannot
submit the same dataset multiple times after an uncertain failure: restrict
retries to steps whose run is idempotent, or add an idempotency key/completion
probe that confirms whether deployment already completed before re-executing.
Preserve retries for safe steps and ensure both request-based and WebDAV deploy
paths are covered.
- Line 146: Update _finish_step_manifest so it adds the synthetic failed
manifest entry only when the step manifest contains no failed file records;
preserve existing merge behavior while preventing ManifestContext.summary() from
counting the same failure twice.
In `@databusclient/workflow/steps.py`:
- Line 90: Update the step output collection around _collect_output_files so
output_files includes only files produced by the current download attempt,
preventing pre-existing files in the persistent workflow directory from being
published. Use a fresh per-attempt directory or download-scoped records, and add
a regression test covering a pre-existing file followed by a retry.
In `@doc/cli-usage.md`:
- Line 219: Replace the corrupted arrow sequence in the CLI description text
with the intended right-arrow character, and ensure the document remains saved
as UTF-8.
- Line 26: Update the vault-token documentation link in the CLI usage text to
target ../README.md#registration-access-token instead of the undefined local
anchor.
In `@doc/examples/workflows/full-pipeline.yml`:
- Around line 18-21: Update the cleanup steps so they do not delete the version
published by the same run: in doc/examples/workflows/full-pipeline.yml lines
18-21 and doc/examples/workflows/nightly-publishing-pipeline.yml lines 19-22,
use delete URIs different from each workflow’s deploy version_id, or rename each
step and describe it as removing demo output.
In `@doc/module-usage.md`:
- Line 6: Change the Deploy heading from H3 to H2 in the module usage
documentation, using the existing heading text and preserving the surrounding
content.
In `@tests/test_format_round_trips.py`:
- Around line 141-149: Update the graph comparison loop in the round-trip helper
to call g1.isomorphic(g2) for each matching context and return False when the
graphs are not isomorphic, replacing the ineffective None check while preserving
the existing identifier lookup and final success path.

Add dry_run to the manifest summary status model.
ManifestContext.summary() counts only "success" and "failed". This new status produces summaries such as total=1, succeeded=0, and failed=0 for a completed dry run. Count dry_run explicitly in the summary and writer output.

Create the output directory before the same-format copy.
Each handler write() calls os.makedirs(os.path.dirname(target), exist_ok=True). This branch does not. If the caller passes an output path in a directory that does not exist yet, shutil.copy2 raises FileNotFoundError while every other conversion path succeeds.

Escape or document the | separator; literal values containing | corrupt the round trip.
Line 288 joins multiple object values with |. convert_csv_to_rdf splits every cell on | at line 415. If one literal contains a | character, the round trip silently produces several wrong triples instead of one. The docstring claims the pipe separator enables "unambiguous splitting on round trip", which does not hold for such values.
Escape the character on write and unescape it on read, or reject/report values that contain |.
🐛 Sketch of an escaping fix
- row.append("|".join(values))
+ row.append("|".join(v.replace("\\", "\\\\").replace("|", "\\|") for v in values))The matching split in convert_csv_to_rdf must then split on unescaped | only and reverse the escaping.

Do not load the Vault token endpoint from the replay manifest.
When replay uses --vault-token for a protected URI, replayParams.authurl reaches __get_vault_access__, which sends the refresh token to that endpoint. Use the trusted default or a validated allowlisted override.

Guard against non-dict dcterms:issued values.
format_summary receives any JSON object loaded from a user-supplied path by manifest summary in databusclient/cli.py. If dcterms:issued is a plain string instead of a {"@value": ...} object, .get("@value") raises AttributeError. The CLI catches only ManifestReplayError, so the user sees a raw traceback.

Alright, I finished the versioning stuff. CodeRabbit added some comments, but I don't think we need to tackle them right now. If you think there's something important among them, of course feel free to address it now. Otherwise, let's concentrate on the report/final submission. Afterwards, we can still have a look at CodeRabbit's suggestions and make fixes if needed.
One important thing: please use Rebase and merge instead of Squash and merge. Otherwise, all changes from the last three months would be squeezed into a single commit. Keeping the individual commits provides better traceability of the work.
