StellaOps Bot 175b750e29 Implement InMemory Transport Layer for StellaOps Router

- Added InMemoryTransportOptions class for configuration settings including timeouts and latency.
- Developed InMemoryTransportServer class to handle connections, frame processing, and event management.
- Created ServiceCollectionExtensions for easy registration of InMemory transport services.
- Established project structure and dependencies for InMemory transport library.
- Implemented comprehensive unit tests for endpoint discovery, connection management, request/response flow, and streaming capabilities.
- Ensured proper handling of cancellation, heartbeat, and hello frames within the transport layer.

Rekor Receipt Remediation · RR1–RR10 (Authority/Attestor/Sbomer)

Source: docs/product-advisories/31-Nov-2025 FINDINGS.md (RR1–RR10). Scope is Rekor receipt schema/catalog and offline verification path consumed by Authority + Sbomer + Attestor.

Deliverables & Evidence Map

ID	Requirement	Deliverable	Evidence & location
RR1	DSSE/hashedrekord only	Policy flag `rk1_enforceDsse=true` and routing to hashedrekord recorded in mirror/receipt policy.	`gaps/artifacts/rekor-receipt-policy.v1.json` (+ DSSE).
RR2	Payload size preflight + chunks	`rk2_payloadMaxBytes=1048576` with chunk guidance; embed in policy.	Same policy JSON (rk2 fields) + example `transport-plan` snippet.
RR3	Public/private routing	`rk3_routing` map per shard/tenant documented.	Policy JSON.
RR4	Shard-aware checkpoints	`rk4_shardCheckpoint="per-tenant-per-day"` + freshness fields.	Policy JSON + checklist section.
RR5	Idempotent submission keys	`rk5_idempotentKeys=true`; include sample request header/claim mapping.	Policy JSON + doc section.
RR6	Sigstore bundles in kits	`rk6_sigstoreBundleIncluded=true` + bundle manifest entry for receipts.	Policy JSON + bundle manifest path `gaps/artifacts/rekor-receipt-bundle.v1.json`.
RR7	Checkpoint freshness bounds	`rk7_checkpointFreshnessSeconds` aligned with mirror/transport budgets.	Policy JSON + metrics note.
RR8	PQ dual-sign options	`rk8_pqDualSign` toggle captured with allowed algorithms.	Policy JSON + crypto profile reference.
RR9	Error taxonomy/backoff	`rk9_errorTaxonomy` and retry rules; deterministic table.	`gaps/rekor-receipt-error-taxonomy.md`.
RR10	Policy/graph annotations	`rk10_annotations` fields for policy hash + graph context inside receipts.	Policy JSON + schema doc.

Schema & bundle layout

Receipt schema: gaps/artifacts/rekor-receipt.schema.json (includes required fields: tlog URL/key, checkpoint, inclusion proof, bundle hash, policy hash, client version/flags, TSA/Fulcio chain, mirror metadata, repro inputs hash).
Bundle manifest: gaps/artifacts/rekor-receipt-bundle.v1.json referencing schema, policy, transport plan, and sample receipts; DSSE envelope rekor-receipt-bundle.v1.sigstore.json when signed.
Hash index: docs/modules/authority/gaps/SHA256SUMS collects schema/policy/bundle hashes and (once signed) DSSE bundle hashes.

Action Plan

Draft rekor-receipt-policy.v1.json with rk1–rk10 flags and shard/routing/size constraints; keep keys sorted.
Author schema rekor-receipt.schema.json with canonical field order and example; ensure inclusion proof + policy hash fields are mandatory.
Add error taxonomy markdown rekor-receipt-error-taxonomy.md with deterministic table (code, classification, retry policy).
Define bundle manifest rekor-receipt-bundle.v1.json (hashes will be appended to SHA256SUMS once generated) and note DSSE envelope requirement.
Mirror status in sprint SPRINT_0314_0001_0001_docs_modules_authority.md (REKOR-RECEIPT-GAPS-314-005) and Authority TASKS.

Determinism & offline

Use sha256sum over normalized JSON and markdown; store in gaps/SHA256SUMS.
No network dependencies; examples should reference local bundle paths.
Signing to follow Authority key once available; until then envelopes remain TODO but paths are fixed.
