Miguel Ángel da4386f0d0 perf(aws-lambda): cloud renders plan without reading video bytes and start chunks sooner (#6194)
* perf(engine): a remote source's tail decodes run many at a time, not one per half-core

* perf(producer): the plan logs where its extract stage spends its time

* perf(engine): a window that ends inside its source takes its frame count without a decode

* test(engine): pin the tail-decode slot test to the windows that decode

* style(engine): format the tail-probe window check

* test(engine): deferred counts match extraction on a B-frame NTSC source; VFR is not deferred

* style(engine): format the tail-probe tests

* perf(aws-lambda): a site stores each video's ffprobe JSON, and the plan reads it instead of probing

* test(aws-lambda): a site stores and hands out each video's probe

* style(aws-lambda): format the probe-facts upload and tests

* perf(engine): a site's stored probe also holds the final-frame timestamp the plan would probe for

* test(engine): drop an unused import

* test(aws-lambda): the stored probe holds the ffprobe JSON and the final frame

* test(aws-lambda): the stored probe holds the ffprobe JSON and the final frame

* perf(producer): a distributed chunk encodes while it captures

* perf(producer): the audio task logs where its mix spends its time

One line per audio stage: prepare, groups, mix, master, encode and the peak check, in ms.

* perf(engine): locked warmup ticks stop sleeping once the page is ready

* perf(engine): a window reaching a stored video's end takes its frame count from stored facts

* fix(producer): the cloud audio task logs its phases

* perf(engine): stored facts keep the last packet length so late-start windows skip the tail decode

* fix(engine): a probe spawns without waiting when no stored facts are declared

* chore(aws-lambda): shorten comments over the line limit

* fix(engine): warmup keeps pacing after a failed tick; stored final frames check ffprobe major

* test(engine): the recorded ffprobe major matches the build's own banner

* test(engine): the version-banner probes go through a named binary like the other spawns

Miguel Ángel 3439433d67 perf(aws-lambda): a render reads a video's audio from a small file stored beside it (#6162)
* perf(aws-lambda): a render reads a video's audio from a small file stored beside it

A video's audio is interleaved with its pictures, so mixing it from the cloud read the whole video (2.5 GB for a 20-minute 4K film) at the Lambda's network speed. lambda sites create now stores each large video's audio packets as a separate object keyed by the video's hash; the audio task reads that when it exists.

* chore(producer): shorten the audio sidecar header comment

* fix(aws-lambda): no audio sidecar for a video whose audio starts late or that has several tracks

* test(producer): format the audio sidecar tests and end their ffprobe options with --

Miguel Ángel 504ec2b307 feat(cli): lambda deploy renders on arm64 by default; --video-arch x86_64 keeps x86 (#6073)
* feat(aws-lambda): price arm64 chunk invocations at the arm64 rate

getRenderProgress takes chunkArchitecture, the architecture of the function
that renders chunks. RenderChunk invocations are priced at its per GB-second
rate, both inline and from a Distributed Map's output; plan, audio and
assemble stay at the x86 rate.

* feat(cli): render chunks on an arm64 function with lambda deploy --video-arch

--video-arch arm64 pushes the arm64 video function image to the stack's own
ECR repository and deploys the template with VideoImageUri set to its digest.
Outside a checkout the image is the one the installed adapter pins; inside a
checkout it must come from HYPERFRAMES_LAMBDA_VIDEO_IMAGE, built from that
checkout. The default stays x86_64, which always sends an empty VideoImageUri
so a redeploy drops a video function rather than keeping it.

destroy deletes the repository, render and progress price chunks at the arm64
rate, and policies lists the ECR actions.

* fix(cli): push the video image only to an ECR repository this stack tagged

* fix(cli): price the plan at the video function's rate now that it runs there

* feat(cli): lambda deploy renders on arm64 by default; --video-arch x86_64 keeps x86

* refactor(cli): drop two doc comments the names already carry

Miguel Ángel 0df088926e feat(aws-lambda): push a prebuilt image to ECR without Docker (#6063)
* feat(aws-lambda): push a prebuilt image to ECR without Docker

Adds pushImageToEcr and ensureEcrRepository to the SDK subpath. The push
reads a single-platform OCI image layout, verifies every blob against its
descriptor before any ECR call, uploads only the blobs ECR lacks through
the layer-upload API, and puts the manifest under a tag, returning the
digest-pinned image URI.

* fix(aws-lambda): keep the ECR client out of the SDK bundle

Like the other AWS SDK clients, @aws-sdk/client-ecr is a dependency the consumer
resolves. Bundled into the ESM SDK it hits a dynamic require of node:https and
the packed package fails to import.

* feat(aws-lambda): build the ECR client from a region like the other SDK calls

* build(aws-lambda): add only the ECR client to the lockfile

* fix(aws-lambda): adopt an existing ECR repository only when it carries the caller's tags

* chore(aws-lambda): raise the size budget for pushing an image to ECR

pushImageToEcr ships in dist (unminified chunk plus its .d.ts); no source maps, tests or release-only files are involved. Built dist, npm pack --dry-run, main versus main plus this branch: +2486 B packed, +8846 B unpacked. The merge-group run measured 73369 packed and 266805 unpacked, which are the new budgets (were 70874 and 258166).

Miguel Ángel 8d562a3d91 feat(aws-lambda): attach the arm64 video image to releases and pin it (#6070)
* feat(aws-lambda): attach the arm64 video image to releases and pin it

The release builds the arm64 video function image from the handler ZIP it
attaches, attaches it as an OCI layout tarball with its sha256, and pins it
in prebuilt/video-image.json, read through prebuiltVideoImage(). A retried
release reuses the image already attached.

* fix(aws-lambda): keep the release pin script out of the published package

pin-handler-zip.ts is run from a checkout by publish.yml; nothing in dist or the CLI imports it. Leaving it out keeps aws-lambda under its size budget with the video image reader added.

Miguel Ángel b501dc4e1b feat(cli): lambda deploy works from the npm install, no repo checkout (#5866)
* feat(cli): lambda deploy works from the npm install, no repo checkout

Each release builds the Lambda handler zip on Linux, attaches it to the
GitHub release, and pins its URL and sha256 (plus the SAM template) in
@hyperframes/aws-lambda before npm publish. Outside a checkout, lambda
deploy downloads that zip, refuses it on a sha256 mismatch, and deploys
it with the packaged template. With neither a checkout nor a pinned zip
it fails up front with one message naming every way out.

* fix(cli): lambda deploy test mocks the pinned-handler reader, comments fit the checks

* test(cli): sam tests deploy from a SAM directory, not the repo root

* chore(aws-lambda): raise the package size budget for the pinned handler template

Measured with pnpm@10.17.1 pack on Linux. Release state (prebuilt/ written by pin-handler-zip): 77,307 packed / 285,654 unpacked. CI state (no prebuilt/): 70,104 / 253,390. Packed is the check's 5% headroom over the release size. Unpacked is 292,000 (2.2% over release) because a 5% budget would put the CI pack under the 85% ratchet.

* test(cli): anchor the docs link check in the lambda deploy fallback test

* fix(cli): lambda deploy logs the verified handler sha256 and keeps a presigned query out of errors

* fix(cli): a redirect-limit download error keeps a signed query out of its message

* test(cli): the redirect-limit leak test types its rejection

* docs(aws-lambda): header comments cut to what the code cannot say

* chore(aws-lambda): size budget fits both the CI and the release package

Miguel Ángel 992df8b203 perf(cloud): move project bytes once through shared content storage (#5772)
* perf(producer): distributed chunks download only the videos they show

A project video under compiled/ that chunks extract their own frames from
now goes only to the chunks that show it, like video-sources/ files. A
chunk skips the readiness wait for a deferred video it does not show, so
it no longer logs media_load_failed for a file it was never given.

* fix(producer): cloud site uploads pack the files their id hashes, symlinks included

* perf(aws-lambda): chunks read only the byte ranges of a video they need

A chunk that extracts its own frames from a deferred project video now
reads it from S3 by byte range through a short-lived pre-signed URL,
instead of downloading and hashing the whole object first. S3 attests the
object's stored SHA-256 before the URL is signed; every other artifact is
still downloaded and verified as before.

* perf(aws-lambda): upload project files once to a shared content-addressed area

* chore(producer): keep planV2 comment share at the base level

* fix(engine): verify the TLS certificate of https video inputs and never surface their signed query

* fix(aws-lambda): renders re-upload a site's expired files instead of failing

* perf(aws-lambda): the plan step probes project videos in place instead of downloading them

* fix(engine): https video reads reconnect and time out, and redaction covers wrapped causes

Signed-URL reads now pass -rw_timeout, -reconnect and -reconnect_delay_max (both Lambda builds accept them) and ffmpeg also -reconnect_on_network_error, so a transient S3 error or a stalled read fails fast or recovers instead of waiting out the process timeout. Query redaction now descends into error.cause.

* fix(aws-lambda): share entry bundles and ratchet package budget

* fix(aws-lambda): site ids uploaded before files.json still render

A site id from an earlier sites create has only sites/<id>/project.tar.gz.
renderToLambda now falls back to that tarball, which the plan step still
reads, and when neither key exists it fails before starting with both keys
named and the fix (run sites create again).

* fix(aws-lambda): renders fail before upload on a stack too old to read sites

A stack deployed before files.json sites untars the site file in its plan
step and fails after four retries. renderToLambda now reads the state
machine definition first and stops with STACK_TOO_OLD and the redeploy
command when the plan task does not list SITE_MANIFEST_INVALID, which new
SAM and CDK stacks now treat as terminal. The README's upgrade section
drops the planProtocol v1 fallback, which hits the same failure.

* docs(aws-lambda): document shared content storage and the upgrade path

The deploy guide still described the tarball HeadObject short-circuit. It
now covers the cas/sha256/ store and its 30-day lifecycle rule, the
STACK_TOO_OLD, SITE_FILES_MISSING and SITE_NOT_FOUND errors, that old site
ids keep working, and that every project uploads once more after the
upgrade. A test keeps a troubleshooting entry for each pre-submit error.

* fix(producer): chunks log each video they read by URL, without its query

A chunk reading a video straight from the bucket left no trace in its log.
It now logs one line per remote source with the path and the URL minus its
query string, so signatures never reach the log.

* fix(engine): ffmpeg errors never keep part of a signed URL's query

A process's stderr tail was trimmed before its URLs were redacted, so a
cut inside a signed URL left a query fragment the URL pattern no longer
matched, and the fragment reached the error. The stderr tail is now
redacted before every trim, and the redactor also strips a signing
parameter cut off from its URL.

* fix(aws-lambda): comments name the site manifest instead of a file path

* fix(engine): stderr redaction survives chunk splits, and every ffmpeg spawn uses it

The stderr tail was redacted on each chunk and then cut, so once a cut
severed a long URL's scheme, the rest of its signature in the next chunk
matched neither pattern. The tail is now kept raw with 2x slack and
redacted only when the text is produced, then cut to size. The unused
producer audioExtractor (its own spawn, unredacted stderr) is deleted and
the parity harness's PCM decode goes through ManagedChildProcess; a test
fails on any ffmpeg/ffprobe spawn in engine, producer or aws-lambda that
does not.

* chore(producer): record the audioExtractor deletion as intended

* fix(engine): drop a signature fragment the stderr tail cut from its URL

The raw tail is kept at twice the cap, but that cut can itself land inside a
signature, and when redaction shrinks the rest below the cap the fragment
survived. After a cut, the severed token is dropped before redaction.

* refactor(engine): name the severed-token drop instead of commenting it

* test(engine): a cut-off URL leaves nothing behind; aws-lambda size budget to measured

* fix(producer): chunk URL-read tests use main's frame list; producer size budget to measured

* chore(producer): size budget at the measured size, no headroom

* chore(producer): size budget back to measured x1.05, the check's own rule

Miguel Ángel 2a14cbc924 perf(aws-lambda): size distributed renders from account concurrency limits (#5813)
* perf(aws-lambda): run chunks through a Distributed Map to lift the 40-chunk cap

The inline Map runs at most 40 chunk renders at once. Both state machine
definitions (CDK and SAM) now use a Distributed Map with STANDARD child
executions, capped at the function's reserved concurrency so chunks past it
queue instead of being throttled. Progress reads each chunk's child
execution history so frames, cost and chunk errors still show up.

* fix(aws-lambda): retry Lambda throttles for minutes and stop on oversized chunks

A throttled task used to burn its four catch-all retries in about 30 s.
It now gets its own jittered backoff of several minutes, because another
render on the same function can still hold the reserved slots. Plan
treats CHUNK_EXCEEDS_WORKER_TIMEOUT as terminal in both definitions.

* chore(aws-lambda): trim stack comments to keep the comment share flat

* fix(aws-lambda): keep render --wait working at hundreds of chunks

Progress polls read the chunk Map Run's counts (one DescribeMapRun) instead of
every child execution's history, take exact chunk frames and cost from the Map
output once it exits, and read failed children only when the counts show a
failure. The SDK client retries throttled calls up to 8 times with backoff.

* feat(aws-lambda): size each render's concurrency to the account instead of a fixed 8

* fix(lambda): keep the concurrency SDK external in published modules

* fix(cli): keep an existing stack's reserved concurrency on redeploy

Redeploying without --concurrency sent ReservedConcurrency=-1, which
removed the cap of 8 that earlier CLI versions reserved by default and
stopped recording it in the state file. The override is now left out
when the flag is omitted, so SAM keeps the stack's current value (a new
stack still gets the template's unreserved default). The state file
records the deployed value, and deploy prints the kept reservation.

* fix(aws-lambda): keep progress working for callers without DescribeMapRun

Callers whose IAM policy came from an earlier `lambda policies user`
lack states:DescribeMapRun, so reading a running Distributed Map threw
AccessDeniedException out of `lambda progress` and `render --wait`
while the render itself went on to succeed. getRenderProgress now
catches only that error around the map-run read, returns the parent
snapshot (status, plan and assemble progress) and adds a warning to
re-apply the policy, which both commands print. Other errors still
throw.

* fix(cli): let the documented deploy policy drop a reserved concurrency

When a redeploy removes a function's reserved concurrency, CloudFormation
calls lambda:DeleteFunctionConcurrency. The policy printed by
`lambda policies role|user` granted only PutFunctionConcurrency, so the
update failed and rolled back. Grant it, and pin it with
states:DescribeMapRun in the required-actions test.

* fix(aws-lambda): read smoke chunk hashes from the Distributed Map output

With chunks in a Distributed Map, their task results live in child
executions, so the smoke gate's chunk-hash check found 0 chunks in the
parent history and failed every v1/v2 comparison. Read Chunks[] from the
RenderChunks / RenderChunksV2 MapStateExited output instead, as
getRenderProgress does. The stack this script deploys only has the
Distributed Map, so the inline-Map path is gone.

* fix(producer): cap a pinned chunk size at the worker concurrency, not 16

With --chunk-size or --target-chunk-frames and no --max-parallel-chunks,
the plan still capped the render at 16 chunks however many workers the
account allowed, so --chunk-size 30 on a 60 s render gave 16 chunks of
113 frames. The cap is now one wave across the worker concurrency, as
the --max-parallel-chunks docs say; 16 remains when the concurrency is
unknown.

* feat(cli): remove a stack's reserved concurrency with --concurrency=none

Since an omitted --concurrency now keeps the stack's reservation, there
was no CLI way back to the unreserved default. --concurrency=none sends
ReservedConcurrency=-1, the state file records the stack as unreserved
and deploy says the reservation was removed. Positive N and an omitted
flag behave as before; any other value is rejected instead of being
silently ignored.

* chore(aws-lambda): raise the package size budget for account-sized concurrency

Measured with pnpm@10.17.1 pack after rebasing on main with the S3 assembly change: 67,763 packed / 244,685 unpacked; the budget is the check's own 5% headroom over that.

They now come from DISTRIBUTED_FPS / DistributedFps / isDistributedFps in

Lambda and Cloud Run renders refused 25 fps although it is an integer

set is now {24, 25, 30, 60} in the producer's config validation, the
plan v2 manifest, the render request mapping, the Lambda and Cloud Run
event types, the CLI's lambda and cloudrun commands and the regression
harnesses.

James Russo 1d636f603c refactor(producer): share plan execution builder (#2906)
## What

Refactor distributed planning around one shared local execution-plan builder:

- `buildLocalExecutionPlan()` now owns compile/probe/extract/audio/freeze.
- Legacy `plan()` remains a deprecated v1 transport wrapper.
- Plan v2 calls the shared builder directly and publishes through the existing manifest/CAS contract.
- Add neutral `createPlanV2FromExecutionPlan()`, `publishPlanV2FromExecutionPlan()`, `getPlanV2ExecutionPlanHash()`, and `PLAN_PROTOCOL_V1` names.
- Retain deprecated v1-named exports and wire aliases.
- Recommend explicit Plan v2 opt-in for new producer, Lambda, and Cloud Run integrations.

## Why

Plan v2 previously looked like it invoked a v1 planner even though v1 and v2 share the same frozen local execution representation. This removes that migration-era coupling while preserving the public minor-version compatibility contract.

## How

The shared builder returns neutral internal execution-plan fields. The v1 wrapper maps those fields back to the existing `PlanResult`; the v2 publisher consumes them directly.

Compatibility is intentional and covered by exact shape tests:

- omitted `planProtocol` still serializes/selects `"v1"`;
- v1 layouts, descriptor-less decoding, event unions, workflow branches, and exports remain;
- the v1 descriptor JSON is byte-identical and `CURRENT_PLAN_PROTOCOL` is an identity-preserving alias;
- v2 manifest bytes, key order, hash framing, and `sourcePlanV1Hash` wire key remain unchanged;
- no enumerable neutral hash field was added to manifests or returned result objects;
- v1/v2 result objects, cloud event payloads, and SDK handle key sets remain unchanged.

## Test plan

- Focused Plan v1/v2/protocol/export/size compatibility: 141 passed
- `@hyperframes/core`: 1,419 passed
- `@hyperframes/producer` unit lane: 990 passed
- `@hyperframes/aws-lambda`: 140 passed
- `@hyperframes/gcp-cloud-run`: 101 passed
- Producer, Lambda, and Cloud Run typechecks
- Repository-wide lint, format check, workspace/package-subpath checks
- Full workspace build
- `git diff --check`

- [x] Unit tests added/updated
- [ ] Manual testing performed
- [x] Documentation updated (if applicable)

* feat: add video frame format render option

* refactor: single source of truth for video-frame-format allow-list

Addresses PR review (Via) on #1481: the ["auto","jpg","png"] set was
declared three times — render.ts (VIDEO_FRAME_FORMATS), server.ts
(inline includes), and renderConfigValidation.ts
(ALLOWED_VIDEO_FRAME_FORMATS) — three boundaries to update when a new
extraction format lands.

Hoist the constant + a reusable `isVideoFrameFormat` type guard into
@hyperframes/engine (where VideoFrameFormat is defined) and route all
three call sites through them. Behavior unchanged; also drops two
`as RenderConfig[...]` casts in favor of the guard (narrowing over
assertion, per repo TS conventions).

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.

JamesandClaude Opus 4.7 d4384722e8 fix(aws-lambda): account for TaskScheduled/TaskSucceeded in cost
The CDK construct compiles tasks.LambdaInvoke to the optimized
arn:aws:states:::lambda:invoke integration, which emits Task* history
events with the Lambda response wrapped in .Payload. getRenderProgress
was only listening for the older LambdaFunction* events, so every CDK-
deployed stack reported $0 total cost and zero invocations on success
— a high-visibility regression that only surfaced when we manually
walked SFN history during a cost-analysis sweep.

Add cases for TaskScheduled (count invocation), TaskSucceeded (parse
Payload + accumulate billed duration / frame counts), and TaskFailed
(record error). Keep the LambdaFunction* paths so anyone wiring the
raw lambda:invokeFunction.sync task type still works. Factor out the
shared FramesEncoded-attribution logic so both branches agree on the
"only RenderChunk frames count" rule.

Tests pin a real-shape regression: replay the inspector-launch
1080p/30fps history (1 Plan + 16 RenderChunks + 1 Assemble) and assert
lambdaUsd lands at ~$0.582 — matching the cost-analysis script's
direct read against SFN history.

James Russo 87fdd556c4 feat(aws-lambda): validate variables + 256 KiB Step Functions input cap (#976)
Add client-side validation for the new config.variables field
(introduced in PR 9.1) and a 256 KiB cap on the full Step Functions
Standard execution input. Both checks throw a typed InvalidConfigError
BEFORE the SDK calls StartExecution — catching the obvious mistakes
locally instead of as a States.DataLimitExceeded 50 ms into the
execution.

validateVariablesPayload walks the variables tree and rejects:
- functions, Symbols, BigInts, non-finite numbers
- undefined leaves (silently dropped by JSON.stringify — would
  surprise the caller when their value doesn't show up in the render)
- non-plain objects (Date, Map, class instances) — Date's toJSON does
  round-trip as a string, but the composition gets a string, not a
  Date, so explicit reject is clearer

validateStepFunctionsInputSize measures the actual UTF-8 byte length
of JSON.stringify(input) against the 256 KiB cap. We use Standard
workflows (per the plan §6.2 / §15.2) for execution-history
visibility, so the cap is 256 KiB (Express would be 32 KiB). The error
message names the actual byte count, the cap, and points at the
templates-on-lambda#working-with-large-variables section so users
know to URL-reference media assets instead of inlining them.

Both helpers are exported from @hyperframes/aws-lambda/sdk so adapters
that build custom Step Functions inputs (batch verbs, future Temporal
ports) can reuse the same gates.

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 6d2569c6bb test(producer): add webm-vp9 distributed regression fixture (#952)
* 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.

* test(producer): add webm-vp9 distributed regression fixture

PR 8.3 of the WebM distributed-rendering plan (v1.5 backlog #1; see
DISTRIBUTED-RENDERING-PLAN.md §7.2). End-to-end regression coverage for
the webm distributed path PRs 8.1 and 8.2 wired up.

Adds packages/producer/tests/distributed/webm-vp9/ matching the
mp4-h264-sdr fixture pattern: a 2-second composition (60 frames @ 30fps)
with text, a crossfade across the frame-30 chunk seam, and a continuous
icon rotation — exercises chunk-boundary continuity for both display
contents and VP9 closed-GOP alpha encoding. `chunkSize: 15` produces 4
chunks so 3 seams are tested, and the crossfade straddles the middle
seam to surface alpha-plane discontinuities introduced by alt-ref drift.

Baseline regenerated inside Dockerfile.test via
`bun run --cwd packages/producer docker:test:update webm-vp9`. Runs in:

  - in-process mode: byte-identical match against baseline ✓
  - distributed-simulated mode: PSNR 56.88-63.49 dB across 100
    checkpoints, well above the 30 dB threshold ✓

Wiring updates required to let webm flow through the harness:

- regression-harness-distributed.ts:
  - checkDistributedSupport() no longer rejects webm. HDR mp4 + NTSC
    fps + non-{24,30,60} fps remain rejected.
  - RunDistributedSimulatedInput.format widened to include webm.
  - Docstring + comments updated.

- regression-harness-distributed.test.ts: webm-rejection test replaced
  with "accepts format=webm" test.

- regression-harness.ts: the now-incorrect format cast at the
  distributed-input call site is dropped; comment about why webm was
  excluded is replaced with "webm is now distributed-supported".

- regression-harness-lambda-local-types.ts: RunLambdaLocalInput.format
  widened to include webm so lambda-local mode can also exercise webm
  fixtures end-to-end.

- aws-lambda webm support (Path A through the Lambda handler):
  - formatExtension.ts: DistributedFormat gains "webm" → ".webm" case.
  - events.ts: RenderChunkEvent / AssembleEvent / PlanLambdaResult
    Format widened to include webm.
  - sdk/validateConfig.ts: ALLOWED_FORMATS gains "webm".
  - handler.ts: downloadChunkObjects format param widened.

The Lambda handler delegates to the producer's assemble() primitive
which PR 8.2 already taught to handle webm (concat-copy + applyFaststart
no-op + muxVideoWithAudio with libopus); no Lambda-side rendering
changes are needed beyond the type/validation surfaces above.

* docs(aws-lambda): drop stale webm rejection from validateConfig docblock

PR #952 review nit (Miguel): the validateConfig.ts file-header comment
still claimed the SDK rejects webm, but the runtime check no longer
does (ALLOWED_FORMATS now includes 'webm'). Update the docblock to
reflect that only force-hdr remains an SDK-side rejection.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* ci(regression): add webm-vp9 to shard-3 + refactor formatExtension

Three follow-ups bundled together (Vai's review feedback on PR #952
plus the fallow audit finding that surfaced when the webm case was
added):

1. **Wire webm-vp9 into CI regression.** The fixture was added in this
   PR but never appeared in any `.github/workflows/regression.yml`
   shard's args allowlist, so the regression harness's positional-args
   gate skipped it in CI. Append `webm-vp9` to shard-3 (which already
   carries `mp4-h264-sdr` + `webm-transparency`) so the fixture runs.

2. **Fix stale "four hard gates" prose in checkDistributedSupport
   docstring.** Earlier in the stack I removed the webm bullet but
   didn't update the count. Two gates remain (fps + hdr).

3. **Refactor `formatExtension` from switch to lookup table.** Adding
   the webm case made the switch dispatch's CRAP score hit 30.0
   (cyclomatic = 5, plus the function's small body). Replaced with a
   `Record<DistributedFormat, string>` lookup, which:
   - drops cyclomatic from 5 → 1,
   - keeps exhaustiveness enforcement at compile time (TS errors if
     a new format gets added to `DistributedFormat` without a
     matching key in the Record literal),
   - drops the runtime `_exhaustive: never` throw, which was only
     guarding against an arbitrary string slipping past TS — a
     caller-side concern, not this function's job.

   The function now reads as a table lookup, which matches what it
   actually does, and the fallow audit now reports zero new
   complexity findings (down from 1).

* 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

even though distributed webm uses `yuva420p`. Every chunk worker
captured opaque RGB via BeginFrame (which doesn't preserve alpha on

* 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 e90ad2da61 feat(cli): add hyperframes lambda deploy/render/progress/destroy (#910)
* feat(cli): add hyperframes lambda deploy/render/progress/destroy

Wraps the @hyperframes/aws-lambda SDK + the Phase 6a SAM template behind
a single CLI surface so an end-to-end render is three commands instead
of the ~8 manual bun+sam+aws steps the smoke script does today:

  hyperframes lambda deploy
  hyperframes lambda render ./my-project --width 1920 --height 1080 --wait
  hyperframes lambda destroy

Subcommands:
  - deploy:        build handler.zip + sam-deploy + persist stack outputs
                   to <cwd>/.hyperframes/lambda-stack-<name>.json
  - sites create:  pre-upload a project to S3 with a stable content hash
                   so re-renders skip the tar+PUT pass
  - render:        start a Step Functions execution; --wait blocks and
                   streams per-chunk progress + accrued cost
  - progress:      one-shot snapshot — status, frames, cost breakdown,
                   errors. Accepts renderId or executionArn
  - destroy:       sam-delete + drop the local state file (S3 bucket
                   is Retain'd by the template; documented in --help
                   and in docs/packages/cli.mdx)

To keep @sparticuz/chromium out of the CLI's transitive deps, this also
adds a dedicated ./sdk subpath export to @hyperframes/aws-lambda; the
CLI imports from @hyperframes/aws-lambda/sdk exclusively. The existing
. barrel still re-exports both handler + SDK for adopters who want one
entry point.

Defaults are deliberately cost-conservative for first-time users:
--concurrency=8 (low enough to never surprise) and --memory=10240 (the
common case; documented for adopters who want to tune down).

Tests: 5 unit tests on the state-file round-trip. CLI integration
against sam local invoke is part of the upcoming PR 6.6 (lambda-local
regression harness).

* refactor(cli): /simplify pass on the lambda command group

Two small cleanups on top of the lambda CLI:

  - Replace parseFormat / parseCodec / parseQuality / parseChromeSource
    (four near-identical helpers) with a single generic parseEnum() +
    typed const-tuple lookups. The four callers now read as one-line
    arrow functions that lift the allowed values out of the function
    body so they're easy to extend.

  - DEFAULT_STACK_NAME was const-declared then re-exported at the
    bottom of state.ts; just mark the const export inline.

No behavior changes. All CLI tests still pass.

* fix(cli): keep @hyperframes/aws-lambda external in the tsup bundle

esbuild can't bundle @hyperframes/aws-lambda's transitive AWS SDK
deps (@aws-sdk/* + @smithy/*) cleanly into a node binary — the
SDK's .browser.js conditional re-exports break the resolver:

  ESM Build failed
    No matching export in "splitStream.browser.js" for import
    "splitStream" (and ~10 similar errors)

Mark aws-lambda as `external` so esbuild doesn't follow it, and
move it from devDependencies to dependencies so the published CLI
can resolve it from node_modules at runtime. The lambda subverb
files dynamic-import only on `hyperframes lambda *` invocation, so
the CLI cold-start cost is unchanged.

The install-size hit (AWS SDK + @sparticuz/chromium ≈ 200 MiB) is
documented as a v1 tradeoff; a future split into a lambda-sdk-only
subpackage can pare this back.

* fix(cli): address PR review on lambda CLI

Two blockers + four important items from Vai's review:

  - `--memory` was parsed and recorded in the local state file but
    never forwarded to `sam deploy` as a parameter override. Worse,
    `progress.ts` then read the *recorded* value for cost math, so
    `--memory 5120` produced wrong cost numbers downstream. Thread
    `LambdaMemoryMb` through samDeploy's --parameter-overrides.

  - `--profile` was only consumed by deploy / destroy. render and
    progress fell back to the default credentials chain — a user
    with `--profile prod` would silently render against their
    default account (wrong-account billing footgun). Set
    `process.env.AWS_PROFILE` (and `AWS_REGION`) in the dispatcher
    before any subverb runs; the AWS SDK reads them natively, so
    render / progress / sites all benefit without each subverb
    threading the flag through the SDK call.

  - `--profile` + destroy now also reads `process.env.AWS_PROFILE`
    as a fallback (matching deploy's existing env fallback).

  - `--wait --json` printed both the start handle AND the final
    progress snapshot, producing two concatenated JSON blobs that
    `jq` rejected. Now emits a single document: handle (without
    --wait) OR final progress (with --wait).

  - Negative integers on `--width` / `--height` / `--chunk-size` /
    `--max-parallel-chunks` / `--memory` / `--concurrency` now fail
    loudly via a new `parsePositiveInt` wrapper instead of flowing
    into the SDK and producing opaque AWS validation errors mid-
    render.

  - `DEFAULT_STACK_NAME` is now centralized to the literal
    `"hyperframes-default"` and consumed from one place. Previously
    the value was assembled as `hyperframes-${"default"}` in three
    sites and hardcoded as `"hyperframes-default"` in a fourth.
    `requireStack`'s hint now matches the dispatcher's default.

The faked `SiteHandle` for `--site-id` keeps the documented
placeholder fields but also surfaces `bucketName` (from PR 909's
extended SiteHandle interface), matching the SDK contract.

All CLI unit tests + the full bundler build still pass.

* fix(cli): keep aws-lambda out of CLI runtime deps

The "Smoke: global install" CI step packs the CLI via `npm pack` and
installs it globally via `npm install -g <tgz>`. npm doesn't understand
the workspace: protocol, so a runtime `dependencies` entry of
`@hyperframes/aws-lambda: workspace:*` blows up with:

  npm error code EUNSUPPORTEDPROTOCOL
  npm error Unsupported URL Type "workspace:": workspace:*

(pnpm rewrites workspace:* on publish; npm pack doesn't.)

Three changes to unblock the smoke + keep the published CLI install
small for users who don't deploy to Lambda:

  - Move `@hyperframes/aws-lambda` from CLI's `dependencies` back to
    `devDependencies`. It's already external in tsup.config.ts; the
    bundle references it via runtime resolution only.

  - Convert the static `import { … } from "@hyperframes/aws-lambda/sdk"`
    in sites.ts / render.ts / progress.ts to `await import()` inside
    each function. tsup with `splitting: false` was inlining those
    static imports at the top of the bundle, which made Node eagerly
    resolve them at CLI startup (MODULE_NOT_FOUND before any lambda
    subcommand even runs). Dynamic imports stay dynamic in the bundle.

  - Add a friendly missing-module check in the lambda dispatcher.
    When a user runs `hyperframes lambda deploy / render / sites /
    progress / destroy` without aws-lambda installed, they now see:

      @hyperframes/aws-lambda is not installed.
      The `hyperframes lambda deploy` command needs it at runtime.
      Install it alongside the CLI:
        npm install -g @hyperframes/aws-lambda

Verified locally: pack + global install + `hyperframes init --example
blank` now succeeds end-to-end (was the same scenario the CI smoke job
runs).

James Russo 34d1f0e1d0 feat(lambda): add TypeScript SDK and CDK construct (#909)
* feat(lambda): add TypeScript SDK and CDK construct

Adds the client-side surface on top of the Phase 6a Lambda handler so
adopters can drive a deployed stack from Node without writing AWS-SDK
boilerplate:

- renderToLambda(opts) starts a Step Functions execution and returns a
  handle. Does NOT poll.
- getRenderProgress({ executionArn }) returns a snapshot of progress,
  frames rendered, cost (Lambda GB-seconds + SFN transitions), errors,
  and the final output object once Assemble completes.
- deploySite({ projectDir, bucketName }) content-addresses the project
  tree, tar.gzs it, and uploads to S3 with a HeadObject short-circuit so
  re-renders of the same tree skip the tar+PUT.
- validateDistributedRenderConfig throws a typed InvalidConfigError
  before StartExecution, so shape errors surface synchronously.
- computeRenderCost is exposed for callers who want to format cost out
  of band.

Also ships HyperframesRenderStack, an aws-cdk-lib L2 construct that
emits the same topology as examples/aws-lambda/template.yaml. Lives on
the ./cdk subpath export so SDK-only consumers don't pull aws-cdk-lib
into their runtime graph (declared as an optional peer dependency).

Tests: 24 new unit tests across the SDK plus 9 CDK synth / contract /
snapshot tests. All 83 tests in packages/aws-lambda/src pass.

* refactor(lambda): /simplify pass on the SDK + CDK PR

Pulls shared logic out so the SDK doesn't re-invent things the handler
and the producer already have:

- `formatExtension` extracted to packages/aws-lambda/src/formatExtension.ts.
  handler.ts and renderToLambda.ts both used identical 12-line copies of
  this switch.
- `PLAN_PROJECT_DIR_SKIP_SEGMENTS` is now exported from
  @hyperframes/producer/distributed. deploySite consumes it instead of
  its own duplicate SKIP_TOP_LEVEL set; the two lists were trivially
  identical and would have drifted silently.
- `FakeS3` + `drainBody` factored out of the two SDK test files into
  src/sdk/__fixtures__/fakeS3.ts. Drops ~110 lines of test-file
  duplication and gives future SDK tests a one-line FakeS3 import.
- S3 URI building in deploySite and renderToLambda routes through the
  existing `formatS3Uri` helper instead of inline `s3://...`
  concatenation; matches the convention already in handler.ts.

Net -133 lines across the touched files. All 83 aws-lambda tests still
pass; all 60 producer distributed tests still pass.

* fix(lambda): bump CDK test timeouts for CI cold-start synth

The bun:test default 5s timeout tripped the first CDK snapshot test
in CI when the cold-start `Template.fromStack(stack)` synth took ~5-8s
on the slowest GitHub Actions runner. Locally on a warm shell the
synth measures <1s, so the failure didn't reproduce until PR #909 hit
CI.

Two changes:

  - Both CDK test files cache one synth in `beforeAll(..., 30000)` and
    reuse the result across every test that uses the default props.
    Each individual test now runs in microseconds (pure assertions
    against the already-synthed template), so the 5s timeout no longer
    applies on the hot path.

  - The two contract tests that exercise non-default props
    (reservedConcurrency, projectName) still synth fresh per-test; they
    get a per-test `it(..., 30000)` timeout.

No behavior changes.

* fix(lambda): address PR review on SDK + CDK construct

Three correctness + ergonomics fixes raised in Vai's review:

  - getRenderProgress over-counted SFN transitions by 3-5×. Step
    Functions Standard Workflows bill per state-entry, not per
    history event. Each Task produces ~5-7 history events
    (Scheduled / Started / Succeeded / TaskStateExited / …);
    counting `events.length` reported the runaway. Switch to
    counting `*StateEntered` events explicitly.

  - assembleComplete + outputFile detection was coupled to the
    Lambda payload's `Action` field. Move both signals onto the
    enclosing state name (`StateExited.name === "Assemble"`), which
    is the state-machine identity rather than the Lambda event
    contract. framesRendered increment moves to the same boundary
    (RenderChunk state).

  - SiteHandle now carries `bucketName` directly so README + CLI
    callers don't have to re-parse `projectS3Uri.split("/")[2]`.

Test updates: getRenderProgress tests wrap renderChunk/assemble
events in matching StateEntered + StateExited pairs so the new
state-name-driven dispatch is exercised end-to-end. SiteHandle
fixture in renderToLambda.test.ts gets the new bucketName field.

All 83 aws-lambda tests still pass.
