docs(plan): mark the projection/payload vocab batch complete

Records the five deliberate deviations from the plan as executed -- Unit A
growing to include Java on a falsified premise, the third breaking change found
in final review, Release 2 cut as MINOR rather than the directed PATCH, the
nested-target rule landing as one loader rule instead of per-port filters, and
the runner.ts guard re-keyed to hasAnyRdbSource.

Also records the batch's recurring failure mode and its five instances, because
the pattern is more useful than any of them individually: documentation
asserting removed behavior as current, each surviving a sweep narrower than the
prose required. The worst was a skill shipped in @metaobjectsdev/sdk that
instructed agents to author metadata this batch made un-loadable -- it survived
four sweeps because they grepped `origin.aggregate` and the file wrote
`aggregate` bare.

+## OUTCOME — batch complete 2026-08-08
+
+**Deviations from this plan, all deliberate and recorded:**
+1. **Unit A grew to include Java.** This plan recorded TS/C#/**Java** as origin-blind reference ports. False for Java — `SpringPayloadGenerator` carried the identical origin dispatch. Root cause: raw NUL bytes made the file test as *binary*, so the environment's `-I` grep wrapper silently returned nothing. Maintainer ruled fix-Java-too. See the NOTE on A's ruling above.
+2. **Three breaking changes, not two.** Final review found the nested-target rule (`field.object @objectRef` must target an `object.value`) is a genuine third break — TS/C#/Python previously accepted a non-value target *and emitted from it*.
+3. **Release 2 cut as MINOR, not the directed PATCH.** Pre-1.0 `^0.20.x` resolves `<0.21.0`, so a patch would be auto-adopted on a routine `npm update` and break adopters with no deliberate action. Maintainer left the call to the executor.
+4. **§4b (payload nested legal-target-set) implemented** as one fail-closed loader rule across four loaders, per the adjudication that overturned a per-port codegen filter.
+5. **`runner.ts` `dbImport`/`dialect` guard re-keyed** to `hasAnyRdbSource` — the release gate caught that it would false-positive on the very sourceless projections this release recommends.
+
+**The batch's recurring failure mode, five instances:** documentation asserting removed behavior as
+current, each surviving a sweep that was slightly narrower than the prose required — a false roadmap
+claim; a Java error message listing the rejected value as allowed (grepped constant *names*, not
+values); an ADR Consequences bullet contradicting its own amendment 35 lines above (grepped subtype
+names, not prose); **a skill shipped in `@metaobjectsdev/sdk` instructing agents to author
+now-illegal metadata** (grepped `origin.aggregate`; the file wrote `aggregate` bare); and `CLAUDE.md`
+listing 2 of 5 origin subtypes (never swept at all). **Lesson: sweep member VALUES as free text,
+spelling-agnostic, and read the hits rather than counting them.**
 - [ ] Release 1 — `0.20.16` / `7.20.16` coordinated PATCH (checkpoint with the maintainer first)
 - [ ] Unit B — doctrine docs amendment (ADR-0007 / FR-024 §7) — docs-only
 - [x] Unit C — Gate 0 adopter scan — **CLEARED 2026-08-06** (see C.0)
