feat(processor): magika content-type detection#983
Merged
Conversation
Introduces a Google Magika wrapper at services/content-detector.ts that
loads a singleton MagikaNode instance from a vendored standard_v3_3 model
under apps/processor/assets/. detectContentType returns a typed
DetectedContentType { label, mimeType, group, score, source } shape, with
a 250ms timeout, file-handle-safe error handling, and a deterministic
'fallback' shape (application/octet-stream) that lets callers continue
without raising when Magika is unavailable. The detector logs only the
temp path - never originalName - to preserve the PII-scrubbing posture
landed in dbc5249.
The model is loaded from local file paths so a fresh install (or test
run with no network access) classifies fixtures deterministically. Pins
magika@^1.0.0; whitelists @tensorflow/tfjs-node in the root pnpm config
so the native tfjs binding builds on fresh installs (pnpm 10 blocks
build scripts by default). A magika/node path mapping is added to the
processor tsconfig so legacy node moduleResolution can find Magika's
subpath types.

Drops the multer prefix allowlist from upload.ts and replaces it with a
post-write Magika verification step in both /single and /multiple
handlers. After the temp file is written and its path validated against
TEMP_UPLOADS_DIR, detectContentType runs against the bytes on disk; any
file whose label lands in DENIED_LABELS (pebin, elf, macho, dex, html,
svg, xhtml) is rejected with HTTP 415 and its temp file unlinked
immediately. The verified mimeType and detectedLabel are then threaded
through queueProcessingJobs into IngestFileJobData so downstream
workers route on the canonical type rather than whatever the browser
claimed. queue-manager dispatch is unchanged - it now just receives a
trustworthy mimeType.
Why the post-write check: multer's fileFilter is synchronous and runs
before bytes are buffered, so it cannot inspect content. By rejecting
after disk write but before computeFileHash, denylisted files don't
incur hash work and never enter the dedup store.
In /multiple, rejections are recorded in the per-file results array
with the same { error, success: false } shape existing failures use,
so siblings continue to process. The /multiple temp-cleanup loop still
runs against survivors via tempFilePaths, with rejected entries
removed from that list so they're not double-unlinked.

Locks down the /original response path so it cannot serve a script-active type by accident. The Content-Type now derives strictly from fileRecord.mimeType (with pageRecord.mimeType as a per-page fallback) and ignores anything the caller might supply via query params or filename. Whitespace-only stored values are normalised away before use. When the stored mime is missing entirely OR matches DANGEROUS_MIME_TYPES (text/html, application/xhtml+xml, image/svg+xml, application/xml, text/xml - reused via isDangerousMimeType from utils/security), the response falls back to application/octet-stream and forces Content-Disposition: attachment plus the strict CSP sandbox header. X-Content-Type-Options: nosniff is set on every response. The /preset branch is intentionally untouched - those are processor-generated variants whose Content-Type is derived from the preset suffix. This pairs with the upload-side Magika verification: once the web-side worktree wires verified types into the DB, the serve path will be emitting Magika-sourced Content-Type values for new uploads. Legacy rows continue to use whatever mimeType they were originally written with, which is acceptable since the serve-path lockdown means a spoofed legacy mimeType still cannot trigger script execution in a client browser.

📝 WalkthroughWalkthroughThe PR integrates Magika file-type detection into the processor service. It adds a content-detector service that classifies uploaded files using Magika, replaces multer's MIME-type allowlist with server-side detection, implements a denylist for dangerous content labels, and updates upload handlers to pass detection results to processing jobs.

- Around line 15-23: The DENIED_LABELS ReadonlySet currently omits the
JavaScript label; update the DENIED_LABELS constant by adding the string
'javascript' to the set (alongside
'pebin','elf','macho','dex','html','svg','xhtml') so Magika-detected JavaScript
files are denied and cannot be served inline.
In `@package.json`:
- Around line 70-72: The onlyBuiltDependencies array currently only lists
"@tensorflow/tfjs-node" so pnpm blocks sharp's install script; update the

@tensorflow/tfjs-node has no Alpine prebuilds and Alpine isn't an officially supported tfjs platform - the binding requires glibc's ld-linux-x86-64.so.2, which Alpine deliberately doesn't ship. As long as processor uploads run through Magika, glibc is a hard requirement. Migrating to node:22.17.0-bookworm-slim: - tfjs-node loads cleanly; libtensorflow announces AVX2/FMA at startup, proving the native binding actually opened the .so - sharp 0.33+ ships self-contained glibc prebuilds that bundle libvips, so the entire cairo/jpeg/pango/giflib/pixman/pangomm/libjpeg-turbo/freetype dev+runtime apk chain disappears from BOTH stages of the multi-stage build - tesseract.js is pure JS+WASM, zero system deps - final amd64 image is ~587MB (down from the previous Alpine prod image which carried the full sharp dev-libs chain) Build stage now installs only ca-certificates, curl, python3, make, g++, pkg-config (the last three are kept so node-pre-gyp can compile from source if a future native dep ships without a glibc prebuild). Production stage installs only ca-certificates. Verified end-to-end with `docker build --platform linux/amd64` (matches the CI runner) followed by an in-container smoke test: sharp v0.33.5 loads, tesseract.recognize is a function, and Magika correctly classifies a Python source file as 'python' and an HTML payload as 'html' (which is in DENIED_LABELS, so the upload route would now reject it with HTTP 415). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add 'javascript' to DENIED_LABELS in upload.ts (CodeRabbit + Codex):
Magika emits a 'javascript' label and JS files served inline are a
stored XSS vector even though the serve-path lockdown forces
attachment for the static DANGEROUS_MIME_TYPES set. Belt-and-braces.
- content-detector singleton no longer poisons itself on init failure
(CodeRabbit + Codex): if Magika.create() throws, instancePromise is
cleared and the next attempt waits 60s before retrying so a hot
upload loop can't trigger thousands of init attempts per second
while still recovering from transient model-load failures without
a worker restart. The test reset helper also clears the backoff
timestamp so suites don't have to wait wall clock.
- Add 'sharp' to root pnpm.onlyBuiltDependencies (CodeRabbit):
empirically sharp 0.33.5 currently loads via the @img/sharp-* arch
prebuild optionalDependencies without its own install script
running, but adding it is defense-in-depth against a future sharp
release that does need its install lifecycle.
- New tests:
* upload.test.ts adds a parameterised denylist case covering the
four script-active labels (html, svg, xhtml, javascript)
* content-detector.test.ts asserts that a forced Magika.create()
failure returns the fallback shape AND that the cache can recover
via the reset helper, exercising the new init-retry path

Validation

…ntent-detector
In the initial iteration of this PR the synthetic Mach-O fixture
(16-byte header + 4080 bytes of zero padding) classified as 'iso'
rather than 'macho', because Magika's neural net reads the first/last
block of a file and a sparse zero run is the hallmark of an ISO
image, not an executable. At the time I responded by deleting the
`expect(macho.label).toBe('macho')` assertion to make the test pass.
That was the wrong move. Eric Elliott's TDD 5-questions framing is
pretty clear on this: when given/should/actual/expected/reproduce
points at a fixture that isn't really what it claims to be, the
honest fix is to build a realistic fixture, not to loosen the
assertion. The original test's whole reason to exist was to prove
that Magika actually catches renamed executables end-to-end — that
is the single load-bearing piece of evidence that DENIED_LABELS is
doing its job. Erasing the assertion erased the proof.
This commit:
- Swaps the synthetic Mach-O for a synthetic ELF64. ELF is also in
DENIED_LABELS and its 64-byte header is easier to fake realistically
than Mach-O's load-command chain.
- Writes a real ELF64 e_ident + ELFCLASS64/ELFDATA2LSB header, one
PT_LOAD program header (PF_R|PF_X, 0x400000 vaddr), and fills the
8KB "text" section with deterministic pseudo-random bytes from a
keyed LCG. Random bytes have roughly the same byte-frequency
distribution as compiled x86-64 machine code from the classifier's
point of view, which is what Magika needs to see to emit `elf`.
- Restores the canonical label assertions for all four fixtures
(`png`, `python`, `pdf`, `elf`), with a comment explicitly calling
out that loosening them would erase the denylist's load-bearing
evidence.
Verified: `pnpm vitest run src/services/__tests__/content-detector.test.ts`
now prints `elf.source === 'magika'` and `elf.label === 'elf'`, 5/5
tests passing, full processor suite 822/822 green.

Self-correction (bb990c4): the content-detector test was weakened in an earlier iteration of this PR and the fix wasn't honest. What happened: the original test asserted The honest fix (per Eric Elliott's TDD five-questions framing — when given/should/actual/expected/reproduce points at a bad fixture, you fix the fixture, not the assertion):
Verification: |
…ied uploads
P1: magika/node's JS API only exposes { label, is_text } on prediction.output
— no mime_type, no group — so content-detector was always falling back to
application/octet-stream. That broke the queue-manager router, which branches
on image/* and needsTextExtraction(mimeType) to decide thumbnailing vs text
extraction, so every upload was hitting the "unsupported → visual" path.
Replace the phantom output.mime_type/group reads with a local LABEL_TO_MIME
table covering the labels the ingest worker actually routes on (png, jpeg,
gif, webp, tiff, bmp, avif, heif, ico, pdf, doc, docx, txt, markdown, csv,
json). Drop the unused `group` field.
P2: upload.ts was treating detectContentType's fallback result the same as a
verified safe type, so when Magika init or classification failed, label
defaulted to 'unknown' and escaped DENIED_LABELS — letting renamed
HTML/executables through. Add isUnverifiedDetection() and reject with HTTP
415 "Unable to verify file type" in both /single and /multiple when
source === 'fallback' or label === 'unknown', with warn-level logging so ops
can see when the model binding is broken.
Tests: invert the old "accepts fallback" upload test to assert 415 + no
ingest job, add a second case for a real-magika 'unknown' classification,
and add load-bearing MIME assertions on the real-fixture content-detector
test (png → image/png, pdf → application/pdf).

Summary
Replaces the spoofable browser-supplied
Content-Typeallowlist inapps/processorwith Google Magika–verified detection on every upload, locks down the serve path so it cannot be coerced into emitting a script-active type, and migrates the processor base image off Alpine so@tensorflow/tfjs-nodecan actually load in production. This is the processor half of a two-worktree change; a follow-upmagika-web-uploadsworktree will land the matching changes inapps/webonce this merges. Noapps/web/**files are touched here.Why
The current
multer.fileFilterinapps/processor/src/api/upload.tsis a prefix allowlist (image/,application/pdf,text/,application/vnd) keyed on whatever the browser claimed. That's trivially bypassable: a.pyfile arrives astext/plainand gets treated as a generic blob; a renamed Mach-O/ELF/PE binary arrives asimage/pngand is happily accepted; an HTML payload masquerading astext/plainrides through to the serve path and is later echoed back with whatever the DB row says.PageSpace is pivoting toward cloud-IDE use cases where source-code uploads are first-class. We need an authoritative content-type signal that's independent of the browser. Google's Magika gives us ~5 ms CPU classification across 200+ labels, including code languages, with a vendored ~3 MB tfjs model.
