Lab #2613: extension push: workflows listed with a shared directory prefix collapse into one workflows.yaml; all but the last are silently dropped

Summary

When a manifest lists several workflows under the same directory (e.g. workflows/a.yaml, workflows/b.yaml, workflows/c.yaml), swamp extension push writes every one of them to the same archive path, extension/workflows/workflows.yaml. Each copy overwrites the previous one, so the published package contains only the last listed workflow. Push and --dry-run succeed with no warning, and the dry-run still reports Workflows (3).

Listing the same files by bare file name (a.yaml, b.yaml, c.yaml) packages all three.

Environment

swamp 20260928.160203.0-sha.b76c8a82 (also observed with 20260917.193606.0-sha.6bf7f212 publishing and 20260925.013241.0-sha.4489c40d pulling via --server)

Steps to reproduce

swamp repo init repro && cd repro; add a no-op model at extensions/models/noop.ts and three workflows workflows/workflow-repro-{alpha,beta,gamma}.yaml (each a single assert step).

manifest-prefixed.yaml:

manifestVersion: 1
name: "@<collective>/wf-collapse-repro"
version: "2026.01.01.1"
paths:
  base: manifest
models:
  - extensions/models/noop.ts
workflows:
  - workflows/workflow-repro-alpha.yaml
  - workflows/workflow-repro-beta.yaml
  - workflows/workflow-repro-gamma.yaml

manifest-bare.yaml is identical except the workflow entries are workflow-repro-{alpha,beta,gamma}.yaml.

swamp extension push manifest-<variant>.yaml --dry-run --visibility private --yes --json — both exit 0, no warning, both list Workflows (3); debug log says Extracted content metadata: … 3 workflows for both.
swamp extension quality manifest-<variant>.yaml --json, then open the cached archive .swamp/cache/packages/<hash>/extension.tar.gz (the same tarball push uploads).

Observed

Manifest	`extension/workflows/` in the archive	Workflows inside
prefixed	`workflows.yaml` only	gamma only
bare (control)	`workflow-repro-alpha.yaml`, `-beta.yaml`, `-gamma.yaml`	alpha, beta, gamma

The prefixed archive's own manifest.yaml still lists all three paths.

In production this shipped a private package whose pulled workflows/ held a single workflows.yaml (the last-listed workflow); the other two returned Workflow not found. Pull itself loses nothing — it installs what the archive contains.

Expected

Either all listed workflows are packaged (keeping each file's basename), or push/--dry-run fails with a clear error. A package must never silently drop workflows, and the dry-run count should match the archive.

Cause (from source)

src/cli/resolve_extension_files.ts:313-317 names each workflow in the archive after the directory in its manifest path — intended for one-workflow-per-folder layouts (namespace-debug/workflow.yaml → namespace-debug.yaml). With workflows/a.yaml, workflows/b.yaml, workflows/c.yaml, all three resolve to workflows.yaml.
The copy loop in src/libswamp/extensions/push.ts:1425-1428 then overwrites that file each time; nothing checks for the name clash.
src/libswamp/extensions/pull.ts:1108 copies the archive's workflows/ folder as-is.

Suggested fix

Apply the directory-name rule only to one-workflow-per-folder layouts; otherwise keep each file's basename.
Fail at push and --dry-run when two entries resolve to the same archive name.
Make the dry-run's workflow count reflect what is actually archived.

Not a duplicate of #2092 / #2434 (serve reload registering pulled workflows).
