U11 [E2E evidence]: live-PG proof for the stranded-column rescue and the planner-lane asymmetry (8 tests, test-only) (#2629)
**Completion bar #3 for my phases.** Test-only, no production changes, no guard-count movement — the two live-PG E2E suites I held during the freeze. ## Why these exist Every U11 slice I shipped closed with the same caveat: *all evidence is unit-level*. Three claims in particular were argued from reading code, and each is the kind a mock would happily confirm: 1. #2515 left `triage` a legal id but removed it from the default lineage. 2. #2603 — `createTask` resolves the workflow's intake column, and an explicit `column` **overrides** it. Nine write sites were removed on that reasoning. 3. #2591 — a card stranded on a legacy planner id is admitted by planning discovery, which is what lets it heal with no data migration. Both suites drive a **real PostgreSQL TaskStore** (per-file throwaway database) and the **real shipped workflows**, not fixture IRs. Claim 3 goes through the real `discoverReadyPlanningTasks` — the method the poll calls. Every assertion is on **observed persisted state** (fresh `getTask` after clearing the task cache), the rule inherited from `workflow-lifecycle-live-e2e.pg.test.ts`, because "a function was called" is exactly what has passed falsely on this program before. ## Two things the E2E found that unit tests did not **The shared fixture's "merged" shape was not #2515's.** Omitting `separateIntake` leaves the hold column with *no* intake trait, so the resolver reports `undefined` — "I have no intake to name" — whereas the shipped merged lineage carries intake **and** hold on one column and reports `[]` — "intake exists and *is* the hold column". Callers treat those differently: `undefined` keeps their legacy default, `[]` positively asserts no dedicated planner lane. Assuming the plain shape was the merged shape is how a test appears to cover #2515 while covering something else. Added an opt-in `mergedIntake` to model the real thing; the third shape is now asserted explicitly. **`insertWorkflowDefinitionSync` throws in backend mode** — it's the SQLite path. The suites use `createWorkflowDefinition` + `writeTaskWorkflowSelection` like the other live E2Es, including binding to the id the *store* allocated rather than the one passed in, which the lifecycle suite documents as a way a renamed-workflow fixture silently resolves to the default IR. ## Fixture changes are opt-in Both new options follow the existing `mergeOrchestration` precedent: seven suites build on this builder and a shared fixture must not silently change an existing suite's subject. ## Naming `workflow-planner-lane-**resolution**-live-e2e` deliberately, to stay distinguishable from #2611's `workflow-planning-lane-live-e2e`. Different subjects — that one drives the real hold-release sweep, this one drives the resolvers the lane guards consume. Near-identical names would invite someone to delete one as a duplicate. ## Verification - 8 new tests green against a real PG store - **Mutation-verified:** disabling the #2591 rescue in `discoverReadyPlanningTasks` fails claim 3, and only claim 3 - Merge gate green (482 + 132 + 10), engine tsc clean, lint clean **Pre-existing failures, not from this PR:** the full live-E2E sweep is 82 tests / 2 failed, both in `workflow-lifecycle-live-e2e.pg.test.ts`. Verified by swapping main's `_workflow-vocabulary-fixture.ts` in and re-running: 2 failed either way, identical. They are main's, and they appeared since my earlier clean run of that suite — worth a look against bar #2. ## What this does not cover Neither suite runs a planning **session** — that lane is the AI, substituted here as `testMode` does in production. So this proves a card is *admitted* and re-homable, not that a full plan-and-release round trip happens. The release half is covered by the existing lifecycle E2E. No changeset: `@fusion/engine` is private and this is test-only. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

FNXC:WorkflowLifecycleColumns 2026-07-30-15:45 (E2E evidence — U11 planner-lane guards):
|
||||
|
||||
Closes the unit-level-only caveat on the planner-lane conversion (#2610). That PR
|
||||
turned two guards from literals into resolved vocabulary and wired four production
|
||||
callers, and its central claim was an ASYMMETRY argued from reading the code:
|
||||
|
||||
the mission-feature guard wants BOTH planner lanes (intake + hold), while the
|
||||
spec-staleness guard wants the DEDICATED planner lane only, because on a merged
|
||||
lineage the planner distinction is carried by STATUS rather than by the column.
|
||||
|
||||
I got that wrong on the first attempt and a pre-existing unit test caught it. This
|
||||
file proves the resolvers behave correctly against a REAL PostgreSQL store and REAL
|
||||
stored workflow definitions, over both board shapes, so the asymmetry is not
|
||||
resting on a mock that happens to agree with me.
|
||||
|
||||
DIFFERENTIAL. Both workflows come from the ONE shared builder and differ only in
|
||||
their column ids (`DEFAULT_VOCAB` vs `RENAMED_VOCAB`) and in whether the planner
|
||||
lane is SPLIT out of the hold column. Any behavioural difference is therefore
|
||||
attributable to vocabulary or shape and nothing else.
|
||||
|
||||
FIXTURE MECHANISM, updated on rebase: the shared builder now emits a SEPARATE intake
|
||||
column by default and merges only when asked (`mergedIntakeAndHold`) or when the
|
||||
vocabulary's `intake` equals its `hold`. An earlier version of this suite carried its
|
||||
own `separateIntake` option for the split shape; that is redundant now and was dropped
|
||||
rather than kept as a second way to say the same thing.
|
||||
|
||||
NAMED `planner-lane-RESOLUTION` to stay distinguishable from PR #2611's
|
||||
`workflow-planning-lane-live-e2e.pg.test.ts`, which is a different subject: that
|
||||
one drives the real hold-release SWEEP, this one drives the resolvers the lane
|
||||
guards consume. Complementary, not overlapping — the near-identical names would
|
||||
have invited someone to delete one as a duplicate.
|
||||
|
||||
LANE. `.pg.test.ts`, skipped via `pgDescribe` when no PostgreSQL is reachable, so
|
||||
the merge gate is unaffected. Throwaway per-file database; never port 4040.

FNXC:WorkflowLifecycleColumns 2026-07-30-14:30 (E2E evidence — U11 stranded-column work):
|
||||
|
||||
WHY THIS FILE EXISTS. My U11 slices closed with unit-level evidence only, and this
|
||||
program has been burned eight times by a test that passed without exercising its
|
||||
subject. Three claims in particular were argued from reading the code rather than
|
||||
from running it, and each is the kind that a mock would happily confirm:
|
||||
|
||||
1. #2515 left `triage` a LEGAL id but removed it from the default lineage, so a
|
||||
card sitting there is declared by nothing. (Argued from the IR; never observed
|
||||
against a real store.)
|
||||
2. #2603 — `createTask` resolves the WORKFLOW'S intake column, and an explicit
|
||||
`column` overrides it. The nine write sites were removed on that reasoning.
|
||||
3. #2591 — a card stranded on a legacy planner id is admitted by planning
|
||||
discovery, which is what lets it heal without a data migration.
|
||||
|
||||
This drives a REAL PostgreSQL TaskStore (per-file throwaway database, never the
|
||||
operator's) and the REAL builtin default workflow — not a fixture IR. Claim 3 is
|
||||
asserted through the REAL `discoverReadyPlanningTasks`, the same method the poll
|
||||
calls.
|
||||
|
||||
ASSERTION RULE, inherited from `workflow-lifecycle-live-e2e.pg.test.ts`: every claim
|
||||
is asserted on OBSERVED PERSISTED STATE — a fresh `getTask` after clearing the task
|
||||
cache — never on "a function was called".
|
||||
|
||||
WHAT THIS DOES NOT COVER, stated because the gap is the point of the file: it does
|
||||
not run a planning SESSION (that lane is the AI, substituted here as `testMode`
|
||||
does in production), so it proves the card is ADMITTED and re-homable, not that a
|
||||
full plan-and-release round trip happens. The release half is covered by
|
||||
`workflow-lifecycle-live-e2e.pg.test.ts`.
