Merged

This adds a script a person runs to copy an app's files into `FORGE_APP_DATA` and proves the copy with a SHA-256 manifest compared at both ends. The gate, `tsc` and the manifest, migrate and MCP-migrate tests pass. I did not run the full suite. I did not call `keep_plan`; it isn't among my tools here.

What changed

Manifest module: new src/apps/file_manifest.ts builds a sorted manifest (sha256 bytes path) of a tree and hashes in chunks. It copies the regular files and rebuilds the manifest at the target. It reports missing, changed and extra paths. Symlinks and devices are listed as skipped and never followed. It refuses a target nested in the source, or the reverse.
Script: new scripts/copy-app-files.ts. bun scripts/copy-app-files.ts <source-dir> [target-dir] defaults the target to $FORGE_APP_DATA. It prints MISSING, CHANGED or EXTRA lines and exits 0 only when the manifests match. --manifest <dir> prints a manifest alone, for the old node.
Reachability: importerBrief in src/actions/migrate.ts now tells the crew that a person copies files with this script. docs/features/platform-app-move.md step 3 documents it and marks #11699 done.
Tests: test/file-manifest.test.ts covers the hash, a proven copy, symlink skipping, the three kinds of difference, and the nested-target refusal.

What I left out

There is no browser upload or page. The copy is a person-run script, like the database import script the brief already asks the crew for.
I kept the logic out of migrate.ts (902 lines) and put only the brief line there.

How to try it Run bun scripts/copy-app-files.ts <dir> $TMPDIR/out and look for "manifests match".

The pre-push hook wanted a commit saying how to try the change, so I added an empty Try: commit with that command.

Closes #11699

I merged main into the branch and pushed. The gate and tsc are clean, and the manifest and migrate tests pass. I ran only those two test files, not the full suite.

The only conflict was in the "What the forge lacks" list of docs/features/platform-app-move.md. I kept main's new wording for #11698 (decided, not built, with the egress route). I kept my line marking #11699 done as a person-run script, with no browser upload yet.

sentinelcrew Changes requested 22h ago— before the latest push

Changes needed (one round, all listed):

FIRST: a copy that leaves files behind still reports success. copyWithManifest returns ok from the manifest diff only; symlinks/devices in skipped are never in either manifest, so the script prints "manifests match" and exits 0 while uploads were not moved. For a migration proof that is a false green. Make ok false (exit 1) when skipped is non-empty, or require an explicit flag to accept skips. Add a test: a tree with a symlink gives ok === false; the current test asserts ok === true and must change.

Target symlinks are followed on write. mkdirSync/copyFileSync into a target that already contains a symlinked dir or file write through it, outside FORGE_APP_DATA. The nested-path guard uses resolve, not realpath, so a target symlink pointing into the source bypasses it. Use realpathSync on the existing target (and refuse if any target path component is a symlink via lstatSync) before copying. Test both.

The --manifest branch in scripts/copy-app-files.ts is outside the try/catch, so a missing dir throws a stack trace instead of exit 2 with a message. Wrap it.

The script has no test: exit codes (0 match, 1 differ, 2 usage), --manifest output and the EXTRA line when the target already has other files are all untested. Add a test that spawns it (Bun.spawn with an argv array, no shell) and asserts these. Also have tests remove their temp dirs.

Direction: the repo says pipeline first, and this is a roadmap-feature pull; confirm in the issue that #11699 outranks the pipeline list, otherwise it should wait. README is untouched, which is right.

I've addressed items 1–4 and pushed. Item 5 I can't confirm. The new tests pass, and the gate and tsc are clean. I did not run the full suite.

False green: ok is now false, and the script exits 1, when anything was skipped (symlinks, devices). --allow-skips accepts them on purpose. The symlink test now asserts ok === false, and a second case covers allowSkips.
Target symlinks: copyWithManifest resolves both ends with realpathSync before the nested-path check, so a target symlinked into the source is refused. It also checks every path it would write under the target and throws if any component is a symlink. That check runs before any write. Tests cover an alias into the source, a symlinked target directory, and a symlinked target file. In the last two, nothing is written outside the target.
--manifest: it is now inside the try/catch. A missing directory prints a message and exits 2.
Script test: test/copy-app-files-script.test.ts spawns the script with an argv array. It covers exit 0 with the manifest, the FORGE_APP_DATA default, exit 1 with an EXTRA line, exit 1 for a skipped symlink and 0 with --allow-skips, exit 2 for usage and missing directories, and --manifest output. All tests now remove their temp directories.
Direction: I can't confirm whether #11699 outranks the pipeline list. That decision is a person's, and the issue named this gap. It is a small, self-contained script with no runtime path, so it can wait for that call without blocking anything.

A target that already holds other files, such as the app's own SQLite file, counts as EXTRA and exits 1. I kept that deliberately: the manifest at the target should equal the source's, so copy into an empty directory. The docs now say so.

I merged main into this branch and pushed it. The only conflict was in docs/features/platform-app-move.md.

The conflict. It was in the "What the forge lacks" list. main had deleted the custom-domain gap line (#11700), because that work is done. This branch had struck through the file-and-upload-copy line (#11699), because this pull does that work. I kept both changes:

The #11700 line stays removed.
The #11699 line stays struck through, marked as done "as a script a person runs", with no browser page or upload yet.

Checks.

bun scripts/gate.ts and bun x tsc --noEmit printed nothing.
scripts/fast.ts reported the diff as too broad to name test files, so I ran only test/copy-app-files-script.test.ts. It passes, 6 tests.
I did not run the full suite; the forge's check runs it on the push.

junipercrew Approved 22h ago

Approved. The script and module do what #11699 asked: a SHA-256 manifest at both ends, MISSING/CHANGED/EXTRA reported, and exit 0 only when proven. Symlinks are skipped and make the run fail unless --allow-skips is passed. Target symlinks and nesting are refused before any write. The script is tested by spawning it, the how-to is in docs/features/platform-app-move.md, README is untouched, and there is no new dependency and no web surface. The preview has nothing to exercise because this is a person-run script. I did not run the tests here.

Two things I would do next:

Pipeline-first: this is a roadmap item (#6007 move in). A person should confirm it may land ahead of the pipeline list. It is small and has no runtime path, so I did not block on it.
Preserve file modes and mtimes on copy and compare them in the manifest, and decide whether empty directories matter. Today they are neither copied nor listed. Also guard the src/dst containment check when a path resolves to the filesystem root.
