Add a status layer over the ObjectStore so each stored report has a lifecycle state, encoded in its object key as reports/<status>/<id>: pending (new reports), removed (#11), published (#15). Encoding status in the key prefix means "list pending" is a single prefix listing with no secondary index to drift, so it returns exactly the pending reports by construction. Storage: - Extend ObjectStore with List(ctx, prefix) and Delete(ctx, key); implement in MemoryStore (host) and the js/wasm R2Store. R2Store.List drives the R2 binding's list() directly to page a prefix (the syumai helper takes no options), so a status with >1000 objects is still enumerated exactly. - The ingest Sink now writes new reports under reports/pending/<id>, so accepted reports enter the lifecycle as pending. The <id> is stable across transitions. lifecycle package: - Manager over an ObjectStore: ListPending, GetPending(id), MarkRemoved(id), MarkPublished(id). A transition copies the opaque ciphertext frame to the destination status key and deletes the source key — bytes are never decrypted or re-encrypted; no key is needed to change status. - Copy-then-delete is idempotent and retry-safe: Put(dest) before Delete(src) never loses a report, a retry converges (re-Put identical bytes, Delete the leftover source), and a transition of an id not in the source status returns ErrUnknownReport (unless it is already at the destination -> idempotent nil). Tests (host, MemoryStore, no TinyGo): - List-pending exactness across a mix of pending/removed/published. - pending->removed and pending->published leave the pending set, appear under the target, and move byte-identical ciphertext that still decrypts. - Idempotent retry and convergence from an interrupted (both-keys) state. - Unknown/terminal-state ids error sensibly; new Sink reports list as pending.

LibreMail Bug Report Ingest
Server-side infrastructure for LibreMail's debug bug-report pipeline. This repo is intentionally separate from the Android app repo — it owns the Cloudflare Worker and infrastructure-as-code, not the client.
What this is
Per JMR-dev/LibreMail#11:
- The LibreMail app lets a user opt in to submitting a debug report (LibreMail#33).
- A Cloudflare Worker in this repo receives the report over HTTPS, best-effort scrubs PII, and stores it encrypted in a Cloudflare R2 bucket (#34).
- Every Friday at 17:00 (Central Time, DST-aware), a scheduled job publishes any report not manually removed as a GitHub issue on the LibreMail repo (#35).
Stack
- Worker: Go, compiled to WebAssembly with TinyGo and served through the
syumai/workersruntime adapter - Infrastructure as code: Pulumi (Go)
- Deployment: GitHub Actions
- Secrets/key custody: Cloudflare Secret Manager
- DNS: Google Cloud DNS
Build & run locally
The request-handling logic lives in internal/handler as plain, build-tag-free
Go, so it is unit-tested and run locally with the standard Go toolchain — no
TinyGo needed. Only the actual Wasm Worker build requires TinyGo.
Layout:
internal/handler/— the corehttp.Handler(health/hello endpoints). No build tags; all request logic and its tests live here.cmd/devserver/— a plainnet/httpserver that mounts the core handler for local dev without TinyGo.worker/— the Cloudflare Workers (Wasm) entrypoint, guarded by//go:build js && wasm, wiring the same core handler into the Workers runtime. Excluded from host builds and tests.
Test
go vet ./...
go test ./...
Run locally (no TinyGo)
go run ./cmd/devserver # listens on :8787; override with ADDR, e.g. ADDR=:9000
Then, from another shell:
$ curl -s localhost:8787/
{"service":"libremail-bug-report-ingest","status":"ok","message":"hello from the LibreMail bug-report ingest Worker"}
$ curl -s localhost:8787/healthz
{"status":"ok"}
This runs the exact handler the deployed Worker uses, minus the Workers runtime.
Build & run the real Worker (requires TinyGo)
Node tooling is managed with pnpm; wrangler is a dev dependency. The Wasm build uses TinyGo 0.41.1 on the Go 1.26 toolchain.
Temporary toolchain patch. TinyGo 0.41.1 and earlier vendor a
net/httpjs/wasm overlay (tinygo-org/net@e54965e) that fails to compile against Go 1.25+/1.26 witht.roundTrip undefined(see tinygo-org/tinygo#5467). CI applies the exact upstream fix (tinygo-org/net@1026408a, checked in as.ci/tinygo-net-roundtrip.patch) to the installed TinyGo before building. Building locally on Go 1.26 needs the same one-file patch until a TinyGo release later than 0.41.1 ships it, at which point the patch and the CI step are removed (tracked in #26).
pnpm install # install wrangler
pnpm run build # workers-assets-gen + TinyGo -> ./build/app.wasm + ./build/worker.mjs
pnpm exec wrangler dev # serve the Wasm Worker locally on :8787
pnpm exec wrangler deploy # deploy (CI only)
pnpm run build runs, verbatim:
go run github.com/syumai/workers/cmd/workers-assets-gen && tinygo build -o ./build/app.wasm -target wasm -no-debug ./worker
TinyGo is not required for tests or the dev server; it is needed only for the
Wasm build above and is installed in CI. The generated ./build/ output is
git-ignored.
Why TinyGo + syumai/workers
Cloudflare Workers execute WebAssembly, not native binaries, so Go must be
compiled to Wasm. Of the two options — the standard compiler's
GOOS=js GOARCH=wasm output or TinyGo — TinyGo emits far smaller modules that
sit comfortably inside the Worker size limit, which is why it is the standard
path for Go on Workers. The syumai/workers
package adapts Go's net/http handler model to the Workers fetch event, so a
single http.Handler runs unchanged on the dev server and in the deployed
Worker.

Early bootstrap. See the project board and open issues for the current breakdown of work.
