📝 Walkthrough

Walkthrough

The exporter now writes OKF v0.2 bundles with generated document metadata, normalized memory sources, and updated indexes. The OKF mapper reads creation times from nested generated metadata and falls back to legacy timestamps.

Changes

OKF v0.2 format

Layer / File(s) Summary
OKF v0.2 bundle serialization
memanto/app/services/okf_export_service.py
The exporter adds frontmatter to context and metrics documents, emits normalized generated metadata for memories, removes timestamp metadata from indexes, and declares okf_version: "0.2".
Generated metadata migration
memanto/cli/migrate/mappers.py
map_okf reads created_at from extra.generated.at and falls back to the top-level timestamp when needed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 8d065

The export format change may omit required context-document metadata when Markdown delimiters are ambiguous, resulting in non-conformant output for affected documents. The PR is otherwise mergeable with explicit owner follow-up on this localized risk.

Assert the migrated created_at value.

The fixture now supplies generated.at, but the test does not verify row["created_at"]. A broken nested lookup could return None while this test still passes.

Add an assertion for 2026-05-28T14:30:00+00:00.

In `@memanto/app/services/okf_export_service.py`:
- Around line 286-293: Update the frontmatter detection in the export logic
around src.read_text and destination_name so the copy path is used only when
text contains a complete parseable frontmatter block with both opening and
closing delimiters; otherwise prepend the required type metadata before writing.
Ensure Markdown files beginning with a thematic break still receive frontmatter.
- Around line 288-290: Update the frontmatter construction in the export flow to
serialize the metadata mapping, including src.stem, with yaml.safe_dump before
concatenating it with text; preserve the existing Context Document type and
title fields while ensuring filenames containing YAML syntax remain valid string
values.

In `@memanto/cli/migrate/mappers.py`:
- Around line 521-525: Update the mapper around extra, generated, and gen_at to
use generated.at when present, otherwise fall back to entry.get("timestamp")
before passing the value to _parse_dt. Preserve the existing handling for
missing or malformed generated metadata.

- Around line 288-297: Update the frontmatter detection in the export copy path
to require an exact opening delimiter and successfully parsed YAML mapping,
rather than merely finding a second thematic break; only then skip generated
type and title metadata. Add a regression test covering a document containing
two Markdown thematic breaks.
