Part 3 of 4 in the scalability refactor. Adds YAML `!include` support
to the org importer and splits molecule-dev/org.yaml (676 lines post-
Phase 2) into 6 team / role files; top-level org.yaml drops to 114 lines
of pure scaffolding.
## Platform changes
New `platform/internal/handlers/org_include.go`:
- `resolveYAMLIncludes(data, baseDir)` — pre-processes a YAML document,
expanding any scalar tagged `!include <path>` with the parsed content
of the referenced file.
- Path resolution via `resolveInsideRoot` so a crafted `!include
../../etc/passwd` can't escape the org template directory (same
defense the existing `files_dir` copy uses).
- Nested includes supported: each included file carries its own search
root (its directory), so `teams/pm.yaml` with `!include research.yaml`
resolves to `teams/research.yaml` — matching the convention of
C-include / Sass @import / most package systems.
- Cycle detection via visited-set keyed on absolute path; belt-and-
braces `maxIncludeDepth = 16` cap in case symlinks or path
normalization defeats the set.
- Inline-template mode (POST /org/import with raw JSON body, no `dir`)
errors cleanly when a file ref is used — can't resolve without a
base.
Wired into both `ListTemplates` (so /org/templates shows an accurate
workspace count after the split) and `Import` (expansion happens before
unmarshal into OrgTemplate).
## Template changes
molecule-dev/org.yaml now contains only:
- name + description
- defaults (runtime, plugins, category_routing, initial_prompt text)
- `workspaces: [!include teams/pm.yaml, !include teams/marketing.yaml]`
New files:
- `teams/pm.yaml` — PM top-level, children are !include refs
- `teams/research.yaml` — Research Lead + Market Analyst + Technical
Researcher + Competitive Intelligence (inline children)
- `teams/dev.yaml` — Dev Lead + FE/BE/DevOps/Security/QA/UIUX (inline)
- `teams/marketing.yaml` — Marketing Lead + DevRel/PMM/Content/
Community/SEO/Social (inline)
- `teams/documentation-specialist.yaml` — leaf
- `teams/triage-operator.yaml` — leaf
## File-size impact
| State | org.yaml lines | total config size |
|---|---:|---:|
| Before (main) | 1801 | 108 KB |
| After Phase 1 (#389) | 1687 | 101 KB |
| After Phase 2 (#390) | 676 | 35 KB |
| After this PR | **114** | **4 KB** (org.yaml only) |
With the 6 team files (total ~570 lines of structural yaml), every file
is now under 230 lines and individually readable without scrolling past
a single team's boundaries.
## Tests
`platform/internal/handlers/org_include_test.go` — 9 cases:
- Flat include (single file, single workspace)
- Nested include (file → file → file)
- Traversal rejection (`../secret.yaml`, `../../secret.yaml`)
- Cycle detection (a↔b)
- Empty path error
- Missing file error
- Inline-template error (baseDir empty)
- No-op when YAML has no includes (safety: we always run the preprocessor)
- **Integration**: load the real `org-templates/molecule-dev/org.yaml`,
resolve includes, unmarshal into OrgTemplate, verify PM + Marketing
Lead are top-level and PM has ≥4 children after expansion.
All 9 pass + existing `TestResolvePromptRef` + `TestOrgYAML` suites stay
green.
## Ownership implication
Each team file can now be owned + reviewed independently. When the
marketing team adds a 7th role, the diff is in `teams/marketing.yaml`
alone — no merge conflicts against PM or research changes in the same
review window. Same for the eventual engineer team, security team, etc.
## What's next
- **Phase 4 (queued):** per-workspace atomization. Each role gets
`<role>/workspace.yaml`; team files shrink to a list of !include
refs. Terminal step in the scalability arc — at that point adding a
new role is one new file under `org-templates/molecule-dev/<role>/`
plus one line in the team's manifest.
