Rebrand-aware merge of Silo-Server/silo-plugin-sdk at 4598c97aa0 (2 upstream commits).

Land with "Create a merge commit". Never squash. The second parent is the real upstream commit; that is what keeps the next sync small.

0 files auto-resolved (hunks: theirs 0, ours 0, same 0, superset 0, import-union 0; delete-over-noise 0).

Generated files taken from upstream (the regen job rebuilds them on this branch):

• pkg/pluginproto/prairie/plugin/v1/marker_provider.pb.go
• pkg/pluginproto/prairie/plugin/v1/metadata_provider.pb.go

The audit comment below lists likely compile breaks and lost Prairie lines. CI must be green, including Prairie invariants; a failing test after a sync usually means Prairie code was lost, not that the test is stale.

Summary by CodeRabbit

• New Features

  • Metadata can now identify the language of titles and descriptions, helping hosts prioritize requested-language text and use fallback text when needed.
  • Marker providers can exchange file details and marker confidence, provenance, and absence information, with compatibility safeguards for older hosts.

• Documentation

  • Expanded guides explain language handling, marker-provider settings and data, compatibility behavior, and safe handling of file hashes.

Walkthrough

The plugin protocol adds language fields to metadata records and file, submission, and absence fields to marker-provider messages. Documentation describes field semantics and compatibility with older hosts. Protobuf tests verify field numbers and older-payload defaults.

Changes: Metadata Language Fields

Layer / File(s)	Summary
Add metadata language fields proto/prairie/plugin/v1/metadata_provider.proto, pkg/pluginproto/prairie/plugin/v1/metadata_provider_test.go, docs/compatibility.md	Metadata records add language fields, and tests verify their field numbers. The compatibility guide describes language values and host handling, along with marker-field compatibility rules.

Marker Provider Fields

Layer / File(s)	Summary
Add marker-provider fields proto/prairie/plugin/v1/marker_provider.proto, pkg/pluginproto/prairie/plugin/v1/marker_provider_test.go, docs/marker-provider.md	Fetch and submit messages add file facts and submission metadata. Marker segments and submissions can indicate absence. Tests verify field numbers and older-payload defaults. Documentation describes provider manifests, field semantics, and compatibility.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: Low · up to 6878e

Older metadata payloads are expected to remain compatible, but tests do not yet protect the new language fields’ default values. Add that coverage before merging or accept the bounded gap.

Full details: Title check

Explanation

The title "Sync upstream Silo-Server/silo-plugin-sdk (2 commits)" names the action and the source, which matches the changeset. The PR merges 2 upstream commits that add metadata language fields and marker contract changes (file facts, absent segments, source/confidence). The title does not name any of these changes, so it is only partially related to the main change. It is also a sync operation label rather than a description of the change itself. This is a partial match, so the check passes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 8 functions across 2 files. (4 skipped: 4 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Cover legacy decoding for all new language fields.

The existing old-payload test does not assert MetadataItem.GetOverviewLanguage() == "", and no equivalent test covers SeasonRecord or EpisodeRecord. These fields are plain proto3 strings, so test their empty default rather than pointer presence. This repository has no consumer call sites for these fields; add downstream consumer coverage where the host ranking logic is implemented instead of adding a synthetic SDK consumer test.
