The first `analyze` after +upgrading logs one line — + +``` +index schema changed (built by an unidentified GitNexus build, this build is ); forcing a full re-analyze so the database is recreated from the current schema. +``` + +— and then performs that full re-analyze itself. The same run stamps the +fingerprint, and every run after it takes the normal incremental path again. + +### What happens on re-index? + +One automatic full re-analyze, once per index. Nothing else changes; the +resulting graph is what the current build would have produced anyway. + +The scope of that one-time cost is worth knowing before you hit it. It is +per **index**, not per machine or per repository — branch-scoped index slots +(#2106) each keep their own `gitnexus.json`, so every slot pays for itself +the first time it is analyzed after the upgrade. On a very large repository +a full re-analyze is substantial, not a blip; plan the first post-upgrade +run accordingly. + +### Why a digest instead of a version number? + +`schemaVersion` was hand-incremented, and it had to predict something a +number cannot know: whether the DDL an on-disk database was created from +matches this build's. It collided with `main` eight times, twice *exactly* — +and an exact clash was the quiet failure. Two builds stamp the same number +over different DDL, the strict `===` reuse gate reads the index as current, +the `CREATE … TABLE` statements are skipped as "already exists", and edges +whose endpoint pair the live database cannot persist are dropped. A wrong +graph, with no error anywhere. + +A derived digest cannot fail that way: two builds agree exactly when their +DDL agrees, so concurrent branches never need renumbering and a mismatch is +always a real mismatch. The retired ladder's per-version rationale (v2 +`BasicBlock.callees` through v35's generated relation cross-product) now +lives only in git history: +`git show 561f913a3:gitnexus/src/storage/repo-manager.ts`. + +### What about rollback? + +Downgrading to an older GitNexus is safe. The older binary looks for +`schemaVersion`, does not find one, treats the index as pre-versioning, and +forces its own full rebuild — the same one-time cost in the other direction, +never a stale or mismatched graph. + +### What if I alternate between an old and a new binary? + +Every switch forces a rebuild. The end-of-run metadata is written as a fresh +object literal rather than merged over the previous file, so a new build's +write drops `schemaVersion` and an old build's write drops +`schemaFingerprint` — neither field survives the other's run, and each binary +then finds its own gate unsatisfied. This hits anyone running a pinned +`npx gitnexus@` alongside a local build, or an editor hook still on +an older release. It is a cost, not a correctness problem: each run rebuilds +against its own schema, and the graph it serves is correct for the binary +that produced it.

Rule 2, the - * phase/framework overlays: every definition label (`NODE_TABLES` minus - * Community/Process/Route/Tool/Folder/BasicBlock) crossed with the labels those - * emitters mint and hang off a resolved anchor — Annotation, Community, - * Process, Route, Tool, File, Record. In both families the endpoint labels are - * LOOKUP RESULTS, not literals at the emit site, so hand-listing could only - * ever declare the pair in the latest stack trace: v32, v33 and #2781 were each - * that same piecemeal fix, and `analyze` kept aborting at `assertDeclaredPair` - * on the next codebase with a different edge shape (`Class→Variable` on Java - * initializers, then `Method→Annotation` on Spring `@Bean`, `Method→File` on a - * Vue Options-API handler, `Namespace→Record` on COBOL `DECLARATIVES`, and - * `Class→Tool` on `@mcp.tool()` applied to a class — four at once, from three - * different emitters).
