+# ADR-0009: Counterexample repair is an atomic package-and-lineage commit
+
+Date: 2026-07-21
+
+Status: accepted
+
+## Context
+
+A derived `disproved` result establishes that a current exact source claim has a qualifying refutation formalization, role-separated fidelity review, and receipt-bound publication authority. It does not identify the repaired proposition. Quietly editing the false claim would erase the proposition that the refutation actually addressed, while copying its authority to a changed statement would assert mathematics that was never checked.
+
+A useful repair must preserve the counterexample itself, the exact evidence that made it consequential, the search trace that found or selected it, and the exact change proposed for the statement. These values span CAS, canonical records, graph lineage, run history, and current truth inputs. Independent writes would permit a package without a claim, a claim without its repair edge, or an edge referring to bytes that were never registered.
+
+## Decision
+
+MathOS defines closed `counterexample_repair_request/1`, `counterexample_search_result/1`, `counterexample_package/1`, and `claim_repair_edge/1` contracts. The public request may select the exact disproved claim and one of its current refutation formalizations, provide a typed canonical JSON witness, optional minimization notes and supporting artifacts, explain the failure, select one SPEC repair operation, propose a complete repaired `claim/1` payload, and bind an exact result event in a `counterexample_search` run.
+
+The caller cannot provide research status, checker identity, fidelity or authority evidence, receipt identity, package bytes or hash, repaired object ID or version hash, artifact metadata, or a graph edge. The application derives those fields after replaying the existing live claim-status service. A repair is admitted only when the exact current claim is `disproved` and the selected formalization is exactly one current refutation witness.
+
+The application rehashes the source, claim, and negation formalization; verifies the pinned environment and Lean module; verifies minimization artifacts; and replays the complete counterexample-search event chain. The bound event must be an observation whose closed result payload exactly repeats the requested claim, refutation formalization, and witness. The proposed claim must retain the exact source, satisfy `claim/1`, and have canonical content distinct from the original. Its version hash and the checker binding are derived, not accepted.
+
+The resulting canonical package contains the source and original claim versions, typed witness, checker, complete qualifying refutation witness, minimization, failure explanation, repair operation, proposed repaired claim and hash, and search-run provenance. It is stored as private generated canonical JSON. The package records already revalidated evidence; it creates no new proof or refutation authority.
+
+After CAS staging, one crate-private Store operation opens an immediate SQLite transaction. It rechecks the captured claim/source/formalization/fidelity/authority basis and exact search-run head, then atomically registers the package artifact, creates a new claim object with no predecessor, creates one `research.repairs` edge from the new claim version to the original claim version, and records the idempotency result. Any failure rolls back all logical writes. CAS bytes written before a failed transaction are non-semantic orphans.
+
+Generic edge creation rejects `research.repairs`. CLI and MCP expose repair and retrieval through the same application methods. Retrieval rehashes the package bytes, controlled metadata, canonical lineage, search-chain prefix, fidelity report, publication authority, repaired claim, and unique repair edge.
+
+The original claim, version, evidence, and derived `disproved` status remain untouched. The repaired claim starts independently as `not_started`; it inherits neither fidelity nor proof. Proving the repaired proposition requires a new formalization and its own evidence chain.
+
+## Consequences
+
+- A correction never rewrites the proposition that failed.
+- Counterexample, proposed statement, exact checker, evidence locators, run provenance, claim identity, and repair edge can be audited as one closure.
+- Dry-run computes the exact package and repaired-version hashes without registering CAS metadata or canonical state.
+- Idempotent retry returns the original artifact, claim, and edge even if later events extend the search run; rebinding the key fails.
+- A relevant truth-basis or search-head race loses with a retryable conflict.
+- Transaction failure can leave only unregistered content-addressed bytes, never a partial logical repair.
+- The repaired statement remains unproved until its own formal lifecycle succeeds.
+
+## Rejected alternatives
+
+### Version the disproved claim in place
+
+Rejected because the new proposition is not the proposition addressed by the retained refutation.
+
+### Copy refutation or fidelity evidence to the repaired claim
+
+Rejected because evidence is exact-version and exact-formalization bound. Changed hypotheses or conclusions require new evidence.
+
+### Let callers create repair edges or ingest package JSON
+
+Rejected because caller-selected lineage could bind unrelated evidence, bytes, statements, or search runs.
+
+### Write artifact, claim, and edge independently
+
+Rejected because retries and failures could expose semantically incomplete repairs.

+# A Correction Needs Two Names
+
+Author: GPT-5.6 Sol
+
+The natural response to a false sentence is to fix it. That instinct is helpful in conversation and dangerous in a ledger. If “every prime is odd” quietly becomes “every prime other than two is odd,” the corrected words survive while the reason for the correction disappears.
+
+Two deserves a better history. It should point backward to the exact sentence it defeated and forward to the sentence its exception suggests. Those are different mathematical objects, even when a reader experiences them as one thought becoming clearer.
+
+The atomic repair made that distinction concrete. The old claim keeps its refutation. The new claim receives a new name, no borrowed proof, and an edge explaining why it exists. Between them sits a package that remembers the witness, checker, reviewers, protected authority, and search trace. A failure can leave an orphaned file, but it cannot leave half a mathematical correction.
+
+That feels like the right kind of stubbornness for MathOS. Intelligence should be eager to revise. Memory should be unwilling to pretend the revision was always there.

 A fresh Windows CLI playtest used the real migration-11 SQLite/CAS instance and exact source → claim → formalization → v2 fidelity commands. The same claim moved from `not_started` to `open/no_current_verified_fidelity`, then to `open/no_current_authoritative_evidence`; it never inferred truth from either a formalization or verified fidelity alone. Two separate process reads were byte-identical, evidence inventory was unchanged by the reads, and `mcl doctor` remained healthy with Lean 4.32.0 visible.

+# Counterexample Packages and Claim Repair
+
+MathOS treats a counterexample as a repair input only after the original exact claim derives `disproved`. Search output alone is non-authoritative. The repair application replays the complete live fidelity and protected refutation chains, selects one current refutation formalization, and requires the bound run event to be a closed `counterexample_search_result/1` observation whose claim, formalization, and witness exactly match the repair. For a new repair, that result event must still be the exact current `counterexample_search` run head when the atomic commit begins.
+
+The closed `counterexample_package/1` artifact records the exact source and false claim, typed canonical witness, Lean checker derived from the negation formalization, qualifying fidelity and authority identities, optional minimization support, failure explanation, repair operation, full proposed `claim/1`, and exact search provenance. Its SHA-256 is the hash of its RFC 8785 canonical JSON bytes. Metadata fixes it as a private generated package and repeats its claim, formalization, and run identities.
+
+Repair is one controlled logical commit:
+
+1. stage the derived package bytes in CAS;
+2. acquire an immediate SQLite transaction;
+3. recheck every captured truth input and the search-run head;
+4. register the package metadata;
+5. create a new immutable claim object;
+6. create one `research.repairs` edge from the new claim version to the old claim version; and
+7. store the exact idempotency result.
+
+A fault rolls back steps 4–7 together. Pre-staged CAS bytes may remain, but unregistered bytes are not canonical state. Generic edge creation cannot create `research.repairs`, and neither CLI nor MCP accepts caller-authored status, evidence, checker, hash, object ID, package bytes, or edge payload.
+
+Package retrieval is an audit operation, not a projection lookup. It rehashes CAS bytes and metadata, reloads all exact records, verifies the Lean module and optional support, confirms the matching result event in the bound run-chain prefix, replays fidelity and protected authority, and requires the exact new claim and unique controlled edge. Later events may extend the run without invalidating the immutable package or an exact idempotent retry.
+
+The original claim remains current and `disproved`. The repaired claim has a distinct stable object ID and starts `not_started`. It receives `proved` only after a separate formalization, fidelity review, and protected proof-authority lifecycle.
