A ledger is an append-only record: every invocation is stored as a receipt that cannot be changed or deleted. Replay and repair are the two ways to handle a receipt after it has been created.\n\n**Replay** means re-running a recorded invocation. You send a receipt ID to a replay endpoint. The system runs the same object with the same input again, producing a new receipt. The new receipt links back to the original. You now have two receipts for the same operation. You can compare them.\n\n**Repair** means creating a corrected invocation linked to a failed one. You send a new invocation with a `repairs` parameter containing the receipt ID of the failed invocation. The system runs the new invocation and creates bidirectional links: the failed receipt points to the repair, and the repair points to the failed receipt. Both receipts remain in the ledger.\n\n### Why They Matter\n\nIn systems where multiple components invoke objects on each other's behalf, errors happen. A model misinterprets a contract. An object returns an unexpected format. A network timeout causes a partial result. Without replay and repair, handling these errors requires either: (a) overwriting the error (destroying the record), or (b) creating disconnected corrections (losing the relationship between error and fix). Replay and repair solve both problems. The ledger stays complete. The lineage stays visible.\n\n### The Key Idea\n\nErrors are not erased. They are linked to their corrections. The ledger is append-only — nothing is deleted. Repair creates lineage, not replacement.\n\n**Replay use cases:**\n\n- **Verification.** A receipt claims that object X returned value Y. You replay it. If the new receipt shows the same result, you have independent confirmation. If not, you have detected non-determinism or a state change.\n- **Idempotency.** You sent an invocation but the network dropped the response. You do not know if it succeeded. You replay the receipt ID. The system returns the result without re-executing (if cached) or re-executes and returns a new receipt you can compare.\n- **Audit.** An investigator asks \"what happened at step 7?\" You replay the receipt for step 7 and show the exact input, output, and object that were involved.\n\n**Repair use cases:**\n\n- **Correction.** The first invocation failed because the input was wrong. You send a repair with corrected arguments. The new receipt links to the failed one. Anyone inspecting the ledger sees both the error and the fix.\n- **Lineage.** A downstream result depends on an invocation that later turned out to be wrong. The repair link lets you trace forward from the error to its correction, and backward from the correction to the error.\n- **Audit.** Nothing is erased. An auditor can see the complete history: what was attempted, what failed, what was corrected, and when. No data is hidden.\n\n### What Replay and Repair Got Right\n\n- **Append-only ledger.** The ledger never loses information. Every invocation, every error, every correction is preserved. This is the property that makes audit possible.\n- **Bidirectional linking.** A repair is not an isolated new receipt. It is explicitly connected to the receipt it repairs. You can navigate both directions.\n- **Deterministic verification.** Replay produces evidence. Either the result matches (confirming reproducibility) or it differs (revealing a state dependency or bug).\n- **No silent fixes.** Because repairs are linked, you cannot hide an error by overwriting it. The error remains visible. This prevents \"sweeping under the rug.\"\n\n### What Replay and Repair Cannot Do\n\n- **Replay does not guarantee identical results.** If the object's state changed between the original invocation and the replay, the result may differ. Replay verifies the operation, not the state.\n- **Repair does not undo side effects.** If the failed invocation already wrote to a database or sent a message, the repair does not reverse those effects. It creates a new, correct invocation. Cleanup of side effects is a separate problem.\n- **Both operations assume the ledger is trustworthy.** If the ledger itself is compromised, replay and repair operate on false data. They are integrity mechanisms, not security mechanisms.\n- **Repair chains can grow long.** A sequence of failed repairs creates a chain of linked receipts. Navigating long chains requires tooling.\n\n### How It Connects to Other Ideas\n\n- **Event sourcing.** In event-sourced systems, state is derived from an append-only log of events. Replay is the mechanism for reconstructing state. Repair is analogous to a compensating event that corrects a prior error.\n- **Blockchain immutability.** Blockchains enforce append-only ledgers cryptographically. Replay and repair achieve a similar property by convention and linking rather than by cryptographic hashing.\n- **Git version control.** Git does not overwrite commits. It adds new commits that correct prior ones. The history remains complete. Repair follows the same principle at the invocation level.\n- **OIP's invocation model.** Every object invocation in OIP produces a receipt. Replay and repair are first-class operations on those receipts, making the system auditable by design.\n\n### Sources\n\n- OIP Protocol Specification — invocation ledger, replay endpoint, and repair linking semantics\n- Fowler, Martin. \"Event Sourcing.\" martinfowler.com (2005) — the append-only event log pattern\n\n---\n\n## Up the tree\n\n- [OIP root](https://miscsubjects.com/a/oip) — protocol root, zero-context entry\n- [Thinker Reference hub](https://miscsubjects.com/a/oip-thinker-reference) — full hierarchy map\n- [Protocol Concepts shelf](https://miscsubjects.com/a/oip-protocol-concepts) — siblings on this shelf\n- [Voxel graph article](https://miscsubjects.com/a/what-is-voxel-graph) — how pages link as voxels\n- [Self-describing protocol](https://miscsubjects.com/a/what-is-self-describing-protocol)\n\n## Related on this shelf\n\n- [What Is Autopoiesis](https://miscsubjects.com/a/what-is-autopoiesis)\n- [What Is Capability-Based Security](https://miscsubjects.com/a/what-is-capability-security)\n- [What Is a Capability Token](https://miscsubjects.com/a/what-is-capability-token)\n- [What Is a Confused Deputy](https://miscsubjects.com/a/what-is-confused-deputy)\n- [What Is Context as Cursor](https://miscsubjects.com/a/what-is-context-as-cursor)\n- [What Is a Convergence Catalogue](https://miscsubjects.com/a/what-is-convergence-catalogue)\n- [What Is a Falsification Surface](https://miscsubjects.com/a/what-is-falsification-surface)\n- [What Is HATEOAS](https://miscsubjects.com/a/what-is-hateoas)\n\n## Machine surfaces\n\n- Public page: `https://miscsubjects.com/a/what-is-replay-repair`\n- JSON article: `https://miscsubjects.com/api/articles/what-is-replay-repair`\n- OIP ask: `https://miscsubjects.com/api/dispatch?ask=What%20Is%20Replay%20and%20Repair`\n","claims":[],"sources":[],"voxels":{"slug":"what-is-replay-repair","counts":{"voxels":0,"sources":0,"edges":0},"note":"slim bundle — full voxels at /api/articles/what-is-replay-repair/voxels"},"constitution":{"url":"https://miscsubjects.com/api/articles/constitution"},"provenance":[{"action":"write","model":"kimi-agent-import","ts":"2026-07-15T04:21:03.153Z","hash":"d4af9171a71cc20e","tokens_in":0,"tokens_out":0}],"contributions":[],"topology":null,"slim":true,"ledger_totals":{"claims":0,"sources":0,"exported_claims":0,"exported_sources":0},"question_graph":{"slug":"what-is-replay-repair","questions":[],"evidence":[],"edges":[],"counts":{"questions":0,"evidence":0,"edges":0}},"verification":{"provenance":{"valid":true,"entries":1,"head":"d4af9171a71cc20e1ca893cb95f0e2b443151f48274dd99e4e2b2903f78dfcca"},"sources":{"valid":true,"entries":0,"head":"genesis"}},"counts":{"claims":0,"sources":0,"provenance":1,"contributions":0,"questions":0,"evidence_ingests":0,"voxel_edges":0},"transport":"Open every URL in this bundle with your browser or web / URL-fetch tool.
