James RussoandClaude Opus 4.8 4da567df22 feat(gcp-cloud-run): Google Cloud Run + Workflows distributed render adapter (#1253) 
* feat(gcp-cloud-run): add Google Cloud Run + Workflows distributed render adapter

Adds @hyperframes/gcp-cloud-run, the GCP counterpart to @hyperframes/aws-lambda
(issue #932). The OSS distributed primitives (plan, renderChunk x N, assemble)
are unchanged; this package is the storage/compute/orchestration glue.

Package: Cloud Run handler (one image, three actions), runs under bun; GCS
transport; in-image chrome-headless-shell resolver; client SDK
(renderToCloudRun, getRenderProgress, deploySite, computeRenderCost); Dockerfile;
Cloud Workflows definition; Terraform module; CLI cloudrun
deploy|sites|render|render-batch|progress|destroy with --output-resolution and
--strict-variables; 62 unit tests + docs + live smoke script.

Shared extraction (removes ~640 lines of adapter duplication): move the
cloud-agnostic config validator + content-hash into producer/distributed; both
adapters import them. Validated end-to-end on GCP at 37.4 dB PSNR vs baseline.

* fix(cli): resolve @hyperframes/gcp-cloud-run in the CLI build + root build

The CLI bundle (esbuild) couldn't resolve `@hyperframes/gcp-cloud-run/sdk`,
failing Build/Typecheck/CLI-smoke (and the perf/windows/regression jobs that
build first). Mirror the aws-lambda handling: mark the gcp adapter + its /sdk
subpath external in tsup.config.ts with a source alias, and add gcp-cloud-run
to the root `build` filter so its dist exists for publish + runtime.

* fix(ci): copy gcp-cloud-run manifest in Dockerfile.test for frozen install

The regression test image runs `bun install --frozen-lockfile` after copying
each workspace package.json individually. The CLI now depends on
@hyperframes/gcp-cloud-run (workspace:*), so the frozen install fails to
resolve it unless its manifest is present. Add the COPY line.

* feat(cli): add machine-sizing flags to `cloudrun deploy`

Closes the parity gap with `lambda deploy` (which exposes --memory etc.).
`cloudrun deploy` now threads --cpu, --memory, --max-instances, and --timeout
into the Terraform apply; omitted flags keep the module defaults
(4 vCPU / 16Gi / 100 instances / 3600s). For finer control, apply the module
directly.

* fix(gcp-cloud-run): address PR review (security, waste, limits, alerts)

- server.ts: bucket-allowlist guard no longer fails open silently. Unset env
  logs a one-time WARNING; "*" is an explicit opt-out; otherwise it enforces.
- server.ts: stop double-shipping audio.aac. It already rides in the plan
  tarball every consumer downloads, so drop the redundant standalone upload
  (plan) + re-download/overwrite (assemble); assemble reads it from the untar,
  falling back to a supplied AudioGcsUri for compat.
- server.ts: chunk extension via path.extname() instead of slice(lastIndexOf).
- workflow.yaml: clamp parallel concurrency_limit to math.min(chunkCount, 20)
  — Cloud Workflows hard-caps concurrent iterations at 20.
- Dockerfile: pin bun (bun-v1.3.9) so an interop change can't silently break
  the image rebuild.
- terraform: add min_instances var (default 0); add a workflow-failure alert
  (finished_execution_count status=FAILED) alongside the request-count one.
- costAccounting: document that displayCost excludes GCS storage/egress.

Verified against the actual APIs: @google-cloud/workflows@4.4.0
ICreateExecutionRequest has no executionId (so the idempotency-token suggestion
isn't available in this client); Workflows concurrency cap is 20; failure
metric is workflows.googleapis.com/finished_execution_count (status label).
174 adapter tests pass, fallow/oxlint/oxfmt/terraform clean.

* fix(gcp-cloud-run): address round-2 review — error code + CFR forwarding

- workflow.yaml: rename the zero-chunk failure code PLAN_TOO_LARGE →
  PLAN_PRODUCED_ZERO_CHUNKS. The old code implied a size-ceiling breach (the
  opposite cause), misleading anyone triaging the alert.
- workflow.yaml: forward Config.cfr to the assemble step
  (`Cfr: ${("cfr" in config) and config.cfr}`). It was read by the handler
  but never sent, so exact-CFR was silently off for every Cloud Run render.
  Uses the same `in`-operator guard already proven in the retryable predicate.

* fix(release): include gcp-cloud-run in set-version PACKAGES list

set-version.ts (driven by release:prepare) bumps an explicit package list to
the shared version on each release. gcp-cloud-run was wired into the build +
publish.yml but missing here, so a release would leave it at a stale version
and publish.yml would push the wrong version. Add it so the new package
version-bumps + publishes in lockstep with the others.

James 71d1889da6 feat(distributed): add optional cfr flag for exact constant frame rate 
Distributed-render output today uses -c:v copy through concat → mux →
faststart, which means PTS timestamps from each chunk pass through
unchanged. Container r_frame_rate is exact (#1040 + this PR's parent),
but stream-level avg_frame_rate stays PTS-derived and can land on
fractional rationals like 27648000/921677 over a 60s render. Same for
sub-ms duration drift.

This is the achievable bar within -c copy stream-copy concat. For most
consumers (browser playback, YouTube, etc.) the difference is invisible.
For downstream tools that strict-check avg_frame_rate or
ms-precision duration (broadcast workflows, frame-accurate compositors,
some third-party transcoders), it matters.

Adds an opt-in cfr config flag (default false). When true, the
assemble step's final pass re-encodes with -fps_mode cfr -r <fps>
instead of -c copy, producing exact CFR output. Trade-off: ~2-5x the
stitch time for a 60s 1080p clip; second-generation H.264 quality loss
is negligible at -crf 18 but is non-zero.

James RussoandClaude Opus 4.7 5d264e146c docs(lambda): document webm support + simplify-review fixes (#953) 
* docs(lambda): document webm support in distributed mode

PR 8.4 of the WebM distributed-rendering plan (v1.5 backlog #1; see
DISTRIBUTED-RENDERING-PLAN.md §7.2). User-facing docs catch up with the
shipped capability.

Updates docs/deploy/migrating-to-hyperframes-lambda.mdx:

- "Output format" row in the migration table now lists `webm` alongside
  mp4 / mov / png-sequence with a note that webm uses libvpx-vp9 +
  closed-GOP concat-copy. HDR mp4 remains the only refused format.

- "No webm distributed" caveat replaced with "webm uses closed-GOP VP9"
  explainer covering the encoder args (`-g <chunkSize>`,
  `-keyint_min <chunkSize>`, `-auto-alt-ref 0`, `-cpu-used 2`), why
  alt-ref disable is load-bearing, and that the output preserves alpha
  via yuva420p with Opus audio.

- Migration checklist no longer asks adopters to filter out webm
  compositions; only HDR-dependent renders need to stay on the previous
  framework.

aws-lambda.mdx doesn't currently call out webm as unsupported (only HDR
in the v1 surface list), so it gets no copy edits beyond the migration
guide.

The internal planning doc (DISTRIBUTED-RENDERING-PLAN.md §7.2, §8,
§12 — kept outside the repo) gets matching updates: format support
matrix flipped ✓, v1.5 backlog #1 marked shipped, HDR promoted to the
new top item, and the rev-12 → rev-13 status line.

* refactor: address simplify-review findings on webm stack

Folds in cleanups identified by a multi-agent code-review pass over the
4-PR webm-distributed stack:

- plan.ts: `resolveEncoderTriple()` webm case now calls
  `getEncoderPreset(quality, "webm")` for its preset string instead of
  hardcoding "good". The hardcode was wrong for `quality: "draft"`
  (`getEncoderPreset` returns "realtime" for that tier) — would have
  silently overridden the draft → realtime mapping for distributed webm
  renders.
- chunkEncoder.ts: trim the new VP9 closed-GOP comment block from ~18
  lines of WHY narration down to the 6 lines that actually explain why
  (alt-ref + cpu-used drift). Match the alpha branch's idempotent-push
  comment to the same standard.
- chunkEncoder.test.ts: drop the duplicate WHY comment that restated
  the implementation comment in plain words.
- webm-concat-copy.test.ts: rewrite the file-header docstring to
  describe the contract being tested instead of the PR-8.1-gating
  history; strip "PR 8.2 / Path A / Path B" references from error
  messages (they belong in PR bodies, not in test output). Consolidate
  the yuva420p alpha smoke into a single `it()` block (was a full
  4-test describe with duplicated setup) — the yuv420p block already
  covers the probe/decode/frame-count contract; the alpha smoke only
  needs to prove the alpha args don't break concat-copy.
- plan.test.ts: drop the "PR 8.1 proved the contract" comment.
- webm-vp9 fixture: drop the aspirational "Other webm-with-audio
  fixtures cover the mux path separately when added" sentence (no
  other fixtures exist). Regenerated the baseline via
  `docker:test:update webm-vp9` to reflect the updated comment.
- migrating-to-hyperframes-lambda.mdx: add a paragraph about
  distributed webm's perf cost — ~10-25% larger files at constant CRF
  due to forced keyframes, and slower per-chunk encode due to
  `-cpu-used 2` being more conservative than the libvpx default.

All unit tests + the webm-vp9 distributed-simulated regression still
pass after these changes.

* fix(cli): accept --format=webm in `hyperframes lambda render`

The CLI's `lambda render` subcommand's FORMATS allowlist and the
`RenderArgs.format` type still narrowed to `mp4 | mov | png-sequence`,
so even though the producer + aws-lambda packages now support webm
end-to-end, the CLI surface rejected it with `--format must be mp4|mov|
png-sequence`. Add webm to both spots and update the --help description.

Surfaced during real-AWS deploy prep — the local lambda-local /
distributed-simulated tests didn't go through the CLI so the gap went
unnoticed.

* fix(producer): font cache writes to /tmp on Lambda (read-only \$HOME)

The deterministic Google Fonts cache was rooted at
`\$HOME/.cache/hyperframes/fonts`, which fails on AWS Lambda — the
runtime's `\$HOME` resolves to a `/home/sbx_*` directory tree that's
read-only. `mkdirSync(..., { recursive: true })` can't create that
path and the plan stage trips with `ENOENT: no such file or directory,
mkdir '/home/sbx_user1051/.cache/hyperframes/fonts/space-mono'` on
every Lambda render that pulls a Google Font (i.e. every distributed
fixture using `@import url("https://fonts.googleapis.com/...")`).

Detect Lambda via `\$AWS_LAMBDA_FUNCTION_NAME` and route the cache to
`tmpdir()/hyperframes/fonts` in that case. Lambda's `/tmp` survives
across invocations on a warm container, so cache hit rate is the same
as non-Lambda runs. Also honor an explicit
`\$HYPERFRAMES_FONT_CACHE_DIR` override for adopters who want a
different location regardless of the runtime.

Surfaced while verifying webm distributed end-to-end on real AWS — the
same bug affects mp4 fixtures using Google Fonts; webm just happened to
be the one I tried first.

* refactor: extract DistributedFormat type + trim font-cache resolver

Second simplify-review pass on the webm stack flagged two cleanups:

1. **`DistributedFormat` type duplicated 10 times.** Every file in the
   distributed pipeline carried its own copy of
   `"mp4" | "mov" | "png-sequence" | "webm"` — adding a new format
   meant a 10-place edit with no compile-time guarantee they stayed in
   sync. Extract a single source of truth in
   `packages/producer/src/services/distributed/shared.ts`, re-export
   from `@hyperframes/producer/distributed` and
   `@hyperframes/aws-lambda/sdk`, and have all callers pull from
   there. The aws-lambda `ALLOWED_FORMATS` runtime tuple and the CLI's
   `FORMATS` tuple now both use `satisfies readonly DistributedFormat[]`
   so the compiler enforces the runtime allowlist stays in sync with
   the type.

2. **`deterministicFonts.ts` font-cache resolver was over-commented.**
   Trim the 7-line block to 4 lines (drop the aspirational
   "and other read-only-FS execution environments" — only Lambda is
   detected — and the warm-container `/tmp` persistence narration —
   anyone reading already knows Lambda /tmp semantics). Collapse the
   two-step `if (explicit && explicit.length > 0)` into a single
   nullish-coalesce expression now that the empty-string defensive
   check is gone (`process.env.X` is `string | undefined`, no third
   shape to guard against).

Out-of-scope skips (called out by the agents, deferred):
- In-process `RenderConfig.format` and the in-process CLI's
  `render.ts` format union still carry their own inline copies. The
  union happens to coincide today but they're separate concerns —
  leaving them alone limits this PR's blast radius.
- `fontCacheDir(slug)` / `resolveFontCacheRoot()` naming asymmetry
  flagged as taste; skipping.
- Pre-existing redundant `existsSync` before `mkdirSync({ recursive:
  true })` in `fontCacheDir` — out of scope.

All tests + typecheck still pass. Lambda render still works
end-to-end (no functional changes).

* docs(lambda): drop plan-doc reference from migration checklist

PR review feedback: source/docs should not mention the
distributed-rendering planning doc. Tighten the migration checklist
sentence to describe the webm path directly rather than referencing
the doc's version label.

* refactor(producer): split resolveEncoderTriple into mp4 + non-mp4 helpers

CI Fallow audit on PR #953 flagged `resolveEncoderTriple` at CRAP 31.6 —
the function interleaved (a) mp4 codec validation + dispatch, (b) the
non-mp4 codec-rejection throw, and (c) per-format dispatch. Splitting
into `resolveMp4EncoderTriple` + `resolveNonMp4EncoderTriple` drops the
top-level function's cyclomatic complexity below the threshold while
preserving every error message and code path. Behavior unchanged.

Also extracts an `EncoderTriple` type alias so the three functions
share the return shape declaratively rather than repeating it.

James RussoandClaude Opus 4.7 21f5066832 feat(producer): enable webm in distributed mode via concat-copy (#951) 
* feat(producer): enable webm in distributed mode via concat-copy

PR 8.2 of the WebM distributed-rendering plan (v1.5 backlog #1; see
DISTRIBUTED-RENDERING-PLAN.md §7.2). Wires libvpx-vp9 webm through the
distributed pipeline now that PR 8.1 proved concat-copy works.

Architectural decision: Path A (concat-copy) — based on PR 8.1's smoke
test result (9/9 tests pass for both yuv420p and yuva420p VP9 streams).
The simpler architecture wins; no re-encode in assemble, no encode-
parallelism loss.

Changes:

- plan.ts:
  - DistributedRenderConfig.format and PlanResult.format now include
    "webm" — type-level acceptance matches the runtime gate.
  - rejectUnsupportedDistributedFormat() no longer trips on webm. HDR
    mp4 remains the only refused configuration.
  - resolveEncoderTriple() returns libvpx-vp9-software + yuva420p +
    preset="good" for format="webm". yuva420p preserves alpha — the
    format's main reason for existing for web delivery.
  - codec= remains rejected for non-mp4 formats (mov is always ProRes
    4444; webm is always libvpx-vp9). The error message lists all four
    distributed-supported formats.
  - FormatNotSupportedInDistributedError docstring updated to reflect
    the new reality (only HDR is unsupported).

- freezePlan.ts: LockedRenderConfig.encoder gains "libvpx-vp9-software".
  Mirrors libx265-software / prores-software / png-sequence in shape;
  the chunk worker reads this discriminant to decide encode args.

- renderChunk.ts: drops the now-incorrect cast that excluded webm from
  buildSyntheticRenderJob's format input; tightens the preset-format
  cast to include webm.

- assemble.ts: docstring + comment updates. The mp4/mov concat-copy
  path is format-agnostic — webm uses the exact same code (applyFaststart
  is a no-op for webm via the existing chunkEncoder.ts gate;
  muxVideoWithAudio already routes webm to libopus audio).

- planFormatBanlist.test.ts: webm-rejection tests removed; replaced with
  "accepts webm" tests + a HDR+webm combo test that verifies HDR is the
  trip regardless of format.

- plan.test.ts: new describe block pins the webm wiring contract:
  format="webm" produces an encoder=libvpx-vp9-software /
  pixelFormat=yuva420p planDir with closedGop=true and gopSize=chunkSize.

- webm-concat-copy.test.ts (smoke): extended with a yuva420p variant
  that proves the alpha pixel format the distributed pipeline actually
  emits also round-trips through concat-copy. 9/9 tests pass locally.

§8 format support matrix in DISTRIBUTED-RENDERING-PLAN.md is intentionally
left unchanged at this PR — it flips to ✓ in PR 8.4 once the end-to-end
fixture (PR 8.3) is green.

* fix(producer): include webm in plan-time needsAlpha + strengthen alpha smoke

PR review feedback from Miguel and Vai on #951 caught a real bug:
`plan.ts`'s `needsAlpha` disjunction excluded `"webm"`, so the plan
stage froze `forceScreenshot: false` into the `LockedRenderConfig`
even though distributed webm uses `yuva420p`. Every chunk worker
captured opaque RGB via BeginFrame (which doesn't preserve alpha on
Linux headless-shell), and libvpx-vp9 encoded uniformly-opaque alpha
that the encoder then dropped — producing un-keyable webm.

Two changes:

1. **plan.ts**: include `"webm"` in `needsAlpha`. Matches the
   in-process renderer's logic at `renderOrchestrator.ts:1469`
   (`const needsAlpha = isWebm || isMov || isPngSequence`); the two
   sites must stay in sync since the distributed pipeline's PSNR
   regression compares against the in-process baseline.

2. **Smoke test (yuva420p describe)**: source frames now use a real
   alpha gradient (`geq=a='X*255/W'` on top of `testsrc2`) instead of
   `testsrc2 + format=rgba` which was uniformly opaque. The decode-
   pix_fmt assertion is dropped (ffprobe reports `yuv420p` for
   VP9-with-alpha because the alpha lives in a Matroska
   `BlockAdditional` sidecar) and replaced with two stronger checks:
   - `TAG:ALPHA_MODE=1` is present on the stream — proves the
     encoder was actually configured for alpha
   - alpha plane variance after `-c:v libvpx-vp9 -i ... -pix_fmt rgba
     -vf extractplanes=a,signalstats` — proves the alpha sub-stream
     round-trips through concat-copy with spatially-varying content,
     not uniform/dropped alpha
   - decode-test gate is now exit-code-only (was `exitCode || stderr`
     which would flake on chatty ffmpeg `-v error` builds emitting
     non-fatal DTS/container notes)

These checks would have caught the `needsAlpha` bug before review.

* fix(aws-lambda): widen narrow format types to include webm

CI on PR #951 was failing at typecheck/build because the producer's
`DistributedRenderConfig.format` widened to include webm in this PR
but the aws-lambda package's narrow `"mp4" | "mov" | "png-sequence"`
type literals in `events.ts`, `handler.ts`, and `validateConfig.ts`
hadn't kept up. `renderToLambda.ts:87` passed `config.format` (now
including webm) into a parameter typed against the narrow union,
producing TS2345.

This widening originally landed in PR #952 (test fixture PR) but
needs to be atomic with the producer's widening here to keep each
PR independently typecheck-clean.

Also refactor `formatExtension` from a switch dispatch to a
`Record<DistributedFormat, string>` lookup. Adding the webm case
tipped the switch's CRAP to the 30.0 fallow threshold; the lookup
table drops cyclomatic from 5 to 1 with the same compile-time
exhaustiveness guarantee (TS errors on missing entries when
`DistributedFormat` adds a new format). The runtime
`_exhaustive: never` throw was only protecting against a string
slipping past TS; `validateConfig.ts`'s `ALLOWED_FORMATS` already
gates untrusted input at the SDK boundary.

James Russo c50f59a53b feat(lambda): add Lambda handler, ZIP bundling, and BeginFrame probe (#878) 
* feat(lambda): add Lambda handler, ZIP bundling, and BeginFrame probe

Phase 6 of the distributed rendering plan: AWS Lambda turnkey adoption
(see DISTRIBUTED-RENDERING-PLAN.md §11 Phase 6 + §15).

This PR adds the new packages/aws-lambda/ workspace package that wraps
the OSS plan/renderChunk/assemble primitives in an AWS Lambda handler,
plus a build pipeline that bundles the handler + Chromium runtime +
ffmpeg into a deployable ZIP.

Architecture: ZIP deploy (not Docker image), Chrome via @sparticuz/chromium
with chrome-headless-shell fallback, dispatch on event.Action ∈ {plan,
renderChunk, assemble}.

The load-bearing concern — does @sparticuz/chromium's chrome-headless-shell
build honour CDP HeadlessExperimental.beginFrame? — is pinned by the new
scripts/probe-beginframe.ts regression guard. Probe boots the runtime
inside public.ecr.aws/lambda/nodejs:22, navigates to a static page, and
asserts beginFrame returns a PNG buffer. Verified locally + inside the
Docker container; both pass with hasDamage=true.

Sizes (sparticuz source): unzipped 157 MiB, zipped 99 MiB. Well under
the 240 MiB / 150 MiB in-house gates and the Lambda 250 MiB hard ceiling.

This is part of a stack of 8 PRs (3 in Phase 6a, 5 in Phase 6b); this is
PR 6.1.

* fix(lambda): address PR 878 review feedback

- Verify event.PlanHash against the untarred plan.json at the handler
  boundary before invoking the producer primitive. Throws typed
  PLAN_HASH_MISMATCH on divergence so Step Functions routes it as
  non-retryable; previously the field was schema bloat the handler
  ignored, leaving enforcement entirely inside the producer.
- Standardize on MiB throughout build-zip.ts, verify-zip-size.ts, and
  the README. Lambda's hard ceiling is 250 MiB (AWS docs label "250 MB"
  but use binary mebibytes); previously mixed units made the 248 MiB
  budget look like a ~5 MB margin instead of the 2 MiB it actually is.
- stageChromeHeadlessShell now picks Chrome versions via numeric semver
  comparison instead of lexicographic sort+reverse — the latter would
  silently pick "99.x" over "131.x" once Chrome cached three-digit
  majors that aren't width-aligned.
- Drop _setSparticuzChromiumForTests from the public index barrel.
  Test-only DI seam imported directly from ./chromium.js in tests.
- Replace require("node:fs") inside walkSize() with the top-level fs
  imports — file is ESM and the same module is already imported.

* docs(lambda): drop internal plan-doc refs from package README

* ci(windows): fix bun filter UNION bug excluding producer from Windows tests

`bun run --filter "!a" --filter "!b" test` composes as a UNION (any
package matching either negation runs), not an intersection. Effect:
@hyperframes/producer was still being tested on Windows even though
it's explicitly excluded — its regression harness (Docker + LFS golden
mp4 baselines) is Linux-only and was driving the 32min timeout.

Enumerate the packages we DO want to test instead.
