filip131311 b232114422 docs: audit every comment in src against the code it describes (#931)
Audits every comment in `src/` and `scripts/` against the code it
describes.

**462 files, 57 commits, net −8,194 lines.** Comment text only — the
whole branch is code-identical to `main`.

## Method

One subagent per file, strictly sequential. Scope was `src/` +
`scripts/` (459 files); three more files were added at the end because
they carried dead references of the same kind — two test headers citing
design docs that do not exist, and `publish-npm.yml` citing a retired
workflow. Each agent verified every comment — line, block, JSDoc, file
header, trailing — against the surrounding code and the rest of the
repo, following identifiers, paths, tool ids, config keys, env vars and
issue links to see whether they still exist and still behave as
described. Rules:

- **A false or misleading comment is deleted, not reworded.** If a claim
could not be confirmed by reading the source, it went. That is why the
deletion count is so much larger than the rewrite count.
- Survivors are cut to the shortest form carrying something the code
does not already say. Restatement, preamble, hedging, changelog prose
and ASCII banners are gone; the non-obvious *why* stays.
- Preserved byte-identical: license headers, pragmas and directives
(`@ts-*`, `eslint-disable`, shebangs, `/// <reference>`), JSDoc tag
tokens, everything inside a string or template literal, and the sole
comment inside an otherwise empty block (ESLint `no-empty` counts a
comment-bearing block as non-empty).

## Verification

Every file passed two independent gates before being recorded as done:

1. `comments-only` — the required check.
2. A second comment-stripping comparator with a proper mode stack,
written for this pass because `comments-only`'s flat scanner desyncs on
nested template literals and quote-bearing regex literals and then
reports comment lines as code changes. Two files hit that false FAIL
(`utils/android-profiler/pipeline/index.ts`,
`scripts/extract-tools.mjs`); in both the "changed code" it printed was
literally `//` lines, and the second checker confirmed the code was
byte-identical.

After the last file, all 462 changed files were re-checked against
`main` with the same comparator, rather than trusting any agent's
self-report. **459 code-identical; 2 are non-code (`.svg`, `.md`); 1
intentional.**

The intentional one is `packages/argent/scripts/bundle-tools.cjs`: the
changed template literal *is* the comment header of the file it
generates, `packages/native-devtools-android/src/bundled-meta.ts`.
Fixing only the generated file would have been reverted by the next
build, so the generator changed too — and it has been verified to
reproduce the committed generated file byte-for-byte.

## Representative false claims removed

Not wording nits — statements a reader would have acted on:

- **Reversed directions.** `proxyStart`'s JSDoc had the tunnel backwards
(it is a reverse tunnel: the host binds first and the simulator dials
in). A `paste()` doc had the pasteboard copy direction reversed.
- **Contradicted by the code below it.** A timeout budget multiplied by
three where the probes run concurrently — the same comment said so six
lines later. A "warn once" that warns on every call. A "binary search"
that is a linear scan.
- **Named things that do not exist.** A `vega-fast-cli` binary, a
`finish-recording.ts`, a `publish-next.yml` workflow, two
`profiler-react19-*.md` design docs, a `DebuggerTarget.ts`, a commit
hash git does not know, two tool ids, an `ensureEnv` cycle.
- **Wrong by construction.** "Welford accumulators" across four files
where the code keeps naive `n`/`sum`/`sumSq`; `sum`/`sumSq` documented
over `actualDuration` when reduce sums `selfDuration`; a strict-mode
halving written `n/2` where the code ceils; field docs listing enum
values the producers never emit.
- **Guarantees the code does not make.** A validation matrix claiming to
cover "EVERY tool" that skips flagless ones; a Pareto cutoff that
`slice(0, 20)` makes inert; an idempotence claim where the real rule is
at-or-ahead; a capability note describing a clean 400 the shape-based
device resolver can never produce.
- **Unverifiable assertions** about prebuilt binaries, external CLIs and
the cloud SDK — deleted rather than kept as folklore, since nothing in
the repo can confirm them.
- **Stale numbers**: invented Android tool versions, hard-coded tool
counts and description lengths that had drifted.

## Review

A Fable agent reviewed both halves adversarially for over-deletion,
misread code, `no-empty` hazards and byte-identity violations.
Second-half verdict: **SHIP**, with two one-line restores, both applied
in the final commit — the `npm view ""` rationale behind a blank-token
guard, and the note that `argent-mcp` keeps a copy of
`SECRET_PLACEHOLDER_MARKER` it cannot import.

## Code issues surfaced but deliberately not fixed

This pass changes comments only. Eight genuine findings are logged for a
follow-up:

1. `telemetry/src/consent.ts` — a non-ENOENT read error returns null and
falls through to the default-on path, so file errors *can* silently flip
telemetry on.
2. `chromium-server/navigation.ts` — `navigate()` is reachable from
`POST /api/navigate` with only a `typeof === "string"` check; open-url's
schema is a bare `z.string()`, so the "already validated by zod" premise
never held.
3. `http.ts` — `constantTimeEqual` returns early on a length mismatch,
so the auth token's length is observable.
4. `describe/index.ts:~114` — the ios-remote branch passes `{ isTvOs:
false }` unconditionally, so a remote tvOS simulator takes the iOS
ax-service path, though `isRemoteTvOsSimulator` exists and shake/paste
do use it.
5. `devices/boot-device.ts` — `-crash-report-mode never` is passed
unconditionally *and* appended again by the feature-detecting path, so
every emulator spawn passes it twice.
6. `react-profiler/pipeline/04-rank.ts` — `PARETO_THRESHOLD_PCT` is
dead: `slice(0, 20)` always wins.
7. `reaped-sessions.ts` — a user-facing hint string tells the agent that
`react-profiler-start { force: true }` disposes the debugger and
profiler session; it does not. Left byte-identical because it is a
string literal, not a comment.
8. `utils/simctl-backend.ts` — `localSimctl` is exported with no
importers anywhere.

## Docs

No documentation change is needed: this pass touches only source
comments, and no user-facing capability, tool, CLI flag, config key or
flow-file behaviour changed.

Full Argent E2E harness

A release-gating end-to-end test that starts from nothing but a swmansion-argent-*.tgz bundle and exercises the whole product: the install flow, every CLI command, every tool's argument validation, and a happy-path run of every tool that applies against real devices.

Run it on the real Linux box and the real Mac before a release.

Quick start

# from the repo root, with a swmansion-argent-*.tgz present there:
bash scripts/e2e-full/run-e2e.sh

# a subset of phases:
bash scripts/e2e-full/run-e2e.sh --phase install,introspection,validation

# offline core only, driving the unpacked bundle (no npm install, fast):
bash scripts/e2e-full/run-e2e.sh --skip-install --phase introspection,validation

A markdown report is written to scripts/e2e-full/results/report-<ts>.md and the raw per-case log to results/e2e-<ts>.jsonl. The process exits non-zero if any hard assertion failed (skips do not fail the run).

What it does (phases)

phase needs covers
install npm + network npm i -g <tgz>, bundled binaries, init (global + --local), update, uninstall, telemetry, MCP-config generation
introspection --version/--help, tools, tools describe for every published tool, feature flags, server start/status/logs/stop, link/unlink
validation for every tool: missing-required / bad-enum / bad-type rejection (deterministic, no hardware)
android Android emulator happy-path of every touch/gesture/screenshot/app-lifecycle tool
chromium Electron (bundled optional dep) + a display boots a generated Electron app; drives CDP tools (scroll/drag/tabs/cookies/storage)
rn ~/dev/bluesky + Android device debugger + react/native profiler + network chain against the real Bluesky app

Tiers auto-skip (with a recorded reason) when their prerequisites are missing, so a partial run still produces a meaningful report. iOS / tvOS / Vega tiers are intentionally out of scope.

Isolation

Everything runs under a throwaway HOME and npm prefix ($(mktemp -d)), so the real machine's ~/.argent, editor MCP configs, and global packages are never touched — safe to run on a shared box. Add --keep to inspect the sandbox after.

Providing a device

The device tiers need a booted device. Two ways:

  • Inject an already-booted one (recommended on shared/CI machines): --android-serial emulator-5554 (the harness attaches, doesn't boot/teardown it).
  • Let the harness boot it: --android-avd Pixel_9a (uses boot-device). The booted serial is published to the RN tier, so it runs against the same device, and the emulator is shut down in the cleanup phase — after every tier that uses it, and on an aborted run too.

The Chromium tier needs no device — it generates and boots its own Electron app. It requires DISPLAY; on a headless Linux box run the whole harness under xvfb-run, which supplies one. Having xvfb-run merely installed is not enough, because nothing wraps the Electron spawn in it.

RN (Bluesky) tier

E2E_RN_DIR=~/dev/bluesky E2E_RN_PKG=xyz.blueskyweb.app \
  bash scripts/e2e-full/run-e2e.sh --phase rn --android-serial <serial>

Assumes the Bluesky dev-client is already built and installed on the device; the tier skips itself if the package is absent. Pass E2E_RN_BUILD=1 to let it run expo run:android first (slow). It starts Metro if nothing is serving the port and tears down only a Metro it started — one you were already running is left alone.

Flags

--android-avd NAME     boot this AVD via boot-device
--keep                 leave the sandbox dir for inspection
