* 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 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).
