/assemble-ppmplugin

The final step: take the label (manifest.json from /generate-ppmplugin-manifest) and the binaries the build skills produced, zip them into the single <name>.ppmplugin file, and verify the box contains exactly the right items. The output is the deliverable — the file you can hand off / upload. Before zipping, it reconciles the manifest's declared platforms against the binaries that actually built, so the shipped bundle never claims a platform it doesn't contain.

Read shared/ppmplugin-format.md §1 — the bundle layout this skill produces and verifies.

What this skill does NOT do

• Does not author the manifest or build any binary — it consumes the staged outputs of the prior third-party-control skills (manifest + the build skill(s)).
• Does not upload to Dataverse / wire into a canvas app (Stage 3 — deferred).
• Does not build any binary — it consumes whatever the build skills staged (android/<Pascal>Plugin.dex from /build-android-binary and/or ios/<Pascal>Plugin.framework/ from /build-ios-binary) and bundles those present.

Step 1 — Read shared docs + prereq block

1. Read shared/shared-instructions.md and shared/ppmplugin-format.md.
2. Prereq: jar (ships with the JDK). Print the visible block (shared-instructions §9.2):

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 Prereq check — /assemble-ppmplugin
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 🟢 ✓ jar (JDK) available
 🟢 1 check passed, 0 failed. Ready to proceed.

If jar is missing, STOP with BLOCKED: jar not found — install a JDK (JDK 17).

---

Step 2 — Reconcile declared entrypoints against staged binaries (the gate)

The shipped bundle's manifest.json MUST declare exactly the platforms whose binaries are in the zip — no more, no less. The manifest was authored from intent (target choice); this step makes it match reality (what actually built). This is the one place that sees the final set of binaries, so it owns consistency.

1. Read ppmplugin/staging/manifest.json — else STOP with NEEDS_CONTEXT: manifest missing — run /generate-ppmplugin-manifest. Read name for the output filename <name>.ppmplugin (the version is NOT in the filename — it lives in the manifest's version field; the wrap pipeline reads it from there. Still read version to show it in the deliverable report).
2. Declared platforms: is entrypoints.android present? entrypoints.ios?
3. Staged binaries:
   • Android: ppmplugin/staging/android/<dex> exists, where <dex> = entrypoints.android.dex.
   • iOS: ppmplugin/staging/ios/<framework>.framework/ exists (a flat .framework, NOT an .xcframework — §5b), where <framework> = entrypoints.ios.framework. If an .xcframework is staged instead, surface it as a gate — the wrap CI can't ingest it; re-run /build-ios-binary for the flat device-slice framework.
4. Reconcile, per platform:

Declared	Staged	Action
yes	yes	ship it ✓
yes	no	MISMATCH → gate (below)
no	yes	binary present but the manifest won't route it — surface; offer to re-run /generate-ppmplugin-manifest to declare it, or leave it out
no	no	not part of this bundle — ignore

5. If nothing is both declared AND staged → STOP with NEEDS_CONTEXT: no built binary to ship — run a build skill first.

The mismatch gate (declared but not staged). Do NOT silently ship a manifest pointing at a missing binary. The situation is genuinely ambiguous (changed-my-mind vs forgot-to-build), so surface it and ask via AskUserQuestion:

"Manifest declares <platform> but no <platform> binary is staged."

• Build <platform> first — run the build skill (/build-android-binary, or /build-ios-binary for iOS, Mac-only) [invoke it via the Skill tool — execute, don't describe]
• Ship without <platform> — remove entrypoints.<platform> from the staged manifest.json, ship the platforms that ARE built
• Stop

If the user picks "Ship without", edit the staged manifest.json to drop that entrypoint before continuing. After this step, the manifest's entrypoints set equals the staged-binary set exactly.

---

Step 3 — Final validation pass

Re-run the ppmplugin-format §4 validation rules on the reconciled staged manifest.json (it may have been edited in Step 2 or by hand). Also cross-check, for each shipped platform:

• Android: entrypoints.android.dex exactly matches the staged DEX filename.
• iOS: entrypoints.ios.framework matches the staged …/<framework>.framework directory name, and that .framework/ carries the binary + Headers/<framework>.h + Modules/module.modulemap + Info.plist (the wrap-CI requirements — /audit-ppmplugin does the deep check; flag here if any are obviously absent).

If validation fails, STOP with BLOCKED: manifest validation — <rule> and do not produce the bundle. A .ppmplugin that fails the local compatibility checks is not ready for upload.

---

Step 4 — Zip + verify

Before zipping: if the output ppmplugin/<name>.ppmplugin already exists, do NOT silently overwrite it — ask via AskUserQuestion: Replace [default] / Keep existing (stop, leave the prior bundle untouched). Proceed to zip only on Replace.

1. Zip the manifest plus only the platform folder(s) reconciled as shipped in Step 2. Pass them explicitly so the build dirs (android-build/, ios-build/) are never swept in. jar (JDK) recurses directories, so it handles the iOS .framework tree, and it behaves identically on every OS — only the shell glue differs (§5):

   macOS / Linux (bash):

   mkdir -p ppmplugin
   # list only the shipped platforms, e.g. `android` for Android-only, `android ios` for Both:
   ( cd ppmplugin/staging && jar cMf "../<name>.ppmplugin" manifest.json android ios )
   

   Windows (PowerShell):

   New-Item -ItemType Directory -Force ppmplugin | Out-Null
   Push-Location ppmplugin\staging
   jar cMf ..\<name>.ppmplugin manifest.json android ios
   Pop-Location
   

   (-M = no JAR manifest entry; the bundle's manifest.json is our own. Drop ios (or android) from the argument list if that platform isn't shipped.) On Replace (confirmed above), the prior bundle is overwritten.

2. Verify layout — list and assert it matches the reconciled manifest exactly:

   jar tf ppmplugin/<name>.ppmplugin
   

   Android-only expects exactly:

   manifest.json
   android/<Pascal>Plugin.dex
   

   A Both bundle also has ios/<Pascal>Plugin.framework/… entries (flat framework — binary + Headers/ + Modules/module.modulemap + Info.plist). STOP with BLOCKED: unexpected bundle contents (and the actual listing) if: a build dir leaked in (android-build/, ios-build/), a stray file appears (.DS_Store, META-INF/), an ios/<…>.xcframework/ is present (must be a flat .framework), or a declared platform's binary is missing. The bundle must contain exactly the manifest + the entrypoints' binaries — nothing else.

---

Step 5 — Report

Update the ## ppmplugin (third-party controls) block in .extension-state.md: Bundle: <name>.ppmplugin assembled <ISO timestamp> (v<version>, platforms: <android[,ios]>). Print the deliverable as a visible fenced block (shared-instructions §9.1, informational form):

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 .ppmplugin ready
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 ppmplugin/pen-input.ppmplugin   (v0.1.4, Android-only)
 Contents:
   manifest.json
   android/PenInputPlugin.dex
 Next: /audit-ppmplugin — verify the bundle is upload-ready before shipping it.
       (Then: deploy the dispatcher PCF via /publish-pcf-companion, and upload the
        .ppmplugin via the wrap wizard — Stage 3, not yet a skill.)

Then offer the next step via AskUserQuestion (shared-instructions §9.1 — invoke the chosen skill via the Skill tool; execute, don't describe):

• Run /audit-ppmplugin (recommended — the final upload-readiness gate: validator rules + DEX SDK-leakage scan + iOS framework checks)
• Run /publish-pcf-companion (deploy the dispatcher PCF to a Power Platform env)
• Stay — I'll inspect the bundle first

(When /assemble-ppmplugin runs as an internal stage of /generate-ppmplugin, the orchestrator invokes /audit-ppmplugin automatically and this gate is skipped.) Return DONE with the bundle path.
