JVNAUTOSCI-2592 preserve retry authority and bound KR read-back

[witbrock]

Outcome

Makes represented spreadsheet/KR materialisation retry authority durable across repo-seed upgrades and removes unnecessary Atlas-heavy relation expansion from deterministic concept and relationship read-back.

Live evidence

• A seed v6 upgrade advanced the live marker without storing either concept read retry policy because retry policy was omitted from export/fingerprint and drift-comparison surfaces.
• After forced publication, a live fetch_concept timeout correctly retried once, proving executor semantics were sound.
• Both attempts still exceeded 20 seconds. Telemetry showed the expanded read materialising a broad concept preview (about 825 concept rows), while the deterministic states consume only core relationships; description evidence already has a separate predicate-scoped read.
• The relationship item had the same unused expansion twice per asserted edge.

Changes

• Serialise state retry_policy in repo-seed authority export.
• Include retry_policy in materialisation drift comparison.
• Use canonical retry keys so publish/load/export round trips are stable.
• Add an attested v6 legacy digest so the current reviewed live authority can migrate normally to v7.
• Keep retries only on four leaf read states; writes and outer loops remain fail-fast.
• Make deterministic concept/source/target read-back a plain exact fetch_concept; retain core relationship mappings and the separate bounded get_text_relations(hasDescription) read.
• Add export, canonical round-trip, missing-policy drift, stale-marker migration, and bounded-read-shape regressions.
• Advance KR seed to v7 and dependent spreadsheet authority to v20.

Validation

• 17/17 full KR and spreadsheet Vontology service tests pass.
• 21 focused reviewer tests pass.
• Applicable repo-seed affordance tests pass 20/20; the intentionally excluded test requires a configured live/local DB support-concept lookup.
• KR validate-all succeeds for all three workflows.
• Ruff, JSON parse, and git diff --check pass.

Safety

No workbook rows, names, values, file identifiers, or private concept identifiers are included. No write retry is introduced; only idempotent read states retry.

Pull request overview

This PR makes workflow-step retry policy durable across repo-seed export/drift surfaces and reduces KR concept read-back cost by removing an unnecessary relation-expansion request shape, while advancing the KR and dependent spreadsheet seed versions.

Changes:

• Export and drift-compare per-step retry_policy so repo-seed upgrades preserve read-retry authority.
• Update KR materialisation concept read-back to call fetch_concept without expensive relation/text-relation expansion flags, keeping the separate bounded get_text_relations(hasDescription) read.
• Bump KR seed to v7 and spreadsheet programme seed to v20, updating dependent fingerprints and adding regressions.
