docs(nests): refresh all T16 + cliff plans to current state

Browse Source 
8 plan files updated to reflect what's actually shipped vs. what
each doc said before:

- 2026-05-06-cross-stack-interop-test.md: 'Spec — ready to
  implement' → 'Implemented and merged' with pointers to results,
  gap matrix, and closure roadmap.

- 2026-05-06-cross-stack-interop-test-results.md: scenario
  inventory updated to show all branches merged into
  claude/cross-stack-interop-test-XAbYB; suite-flake caveats
  flagged with cross-refs to the routing investigation; file
  inventory now lists BrowserInteropTest + PlaywrightDriver +
  the moved nestsClient/tests/browser-interop/ tree (no more 'in
  sister branches not yet merged' section).

- 2026-05-06-cross-stack-interop-test-gap-matrix.md: T8/T10/T11/
  T12/T13 all show hang ✅ + browser ✅; I13/I14 'NOT YET LANDED'
  callouts removed; the 'in sister branch' qualifier on T13 / I7
  / I6 dropped; coverage-holes section replaced with caveat
  pointers to the routing investigation.

- 2026-05-06-i4-stereo-cross-stack-scenario.md: 'Spec — ready for
  implementation' → 'Landed' with PR #2755 + the three test
  scenarios that ship the assertion.

- 2026-05-06-phase4-browser-harness.md: 'Spec — ready for
  implementation' → 'Landed', with notes on how the implementation
  diverged (used Container.Legacy.Consumer not @moq/watch; cert
  pinning via serverCertificateHashes; I2/I3/I4/I13/I14 originally
  deferred but later landed).

- 2026-05-06-phase4-browser-harness-results.md: status updated to
  reflect 4.D CI removed per maintainer ask; layout note for
  the nestsClient/tests/browser-interop/ relocation; full
  scenario list reconciled with results doc.

- 2026-05-07-late-join-catalog-flake-investigation.md: status
  updated to mention 00f6cba31 + 207057374 were reverted, and
  link to 2026-05-07-moq-relay-routing-investigation.md as the
  action plan. Adds note that the flake also affects four
  browser-tier scenarios after Browser I7 landed.

- 2026-05-01-quic-stream-cliff-investigation.md: adds an HCgOY-
  override banner — recommendation 2 (framesPerGroup = 5) was
  superseded 4 days later by HCgOY field tests landing the prod
  default at 50. Cross-refs the reconciliation + production-
  rerun plans. Open follow-up #3 ('reset to 1') updated with
  the same context.

No code or test changes.

# QUIC stream cliff against nostrnests.com — investigation plan # QUIC stream cliff against nostrnests.com — investigation plan
**⚠️ Recommendation 2 (cadence tuning) was overridden 4 days
later.** Subsequent two-phone production tests on
`claude/fix-nests-audio-receiver-HCgOY` (commit `a36ccb569`,
2026-05-05) showed `framesPerGroup = 5` itself cliffs after ~13 s
on the same production deployment, just slower than `framesPerGroup
= 1`'s 3 s. Production now defaults to `framesPerGroup = 50`
(1 stream/sec). The interop tests still pin `5` because the local
`moq-relay 0.10.25 --auth-public ""` minimal setup hits a *different*
cliff (per-stream byte volume) at 50.
Both values are correct in their own environments. See
`nestsClient/plans/2026-05-07-framespergroup-reconciliation.md`
for the full reconciliation. A planned re-run of the HCgOY field
tests against the current production deployment is queued in
`nestsClient/plans/2026-05-07-framespergroup-production-rerun.md`
to settle whether the two rigs can converge.

**Update 2026-05-05:** the value did NOT stay at `5` — HCgOY field

## Coverage holes ## Coverage state
Scenarios specced as P0 / P1 in the spec but **not yet landed**: All T-series wire fixes (T8, T10–T14) have ≥ 1 cross-stack
asserting scenario landed. Both hang-tier AND browser-tier
mates exist for T8/T10/T11/T12/T13. T14 (GOAWAY) only applies
to the IETF moq-transport target which the production stack
doesn't use.
- **I13** (browser `framesPerGroup=50` long broadcast) — P0 browser-tier. Protects nothing today on the browser path; T11's browser-side coverage is implicit in I1 alone. DoD #5 (gap matrix coverage) closed.
- **I14** (WebCodecs warmup × CSD-skip) — P0 browser-tier. Hang-tier I11 catches T8 on the wire; without I14 a browser-side regression where the WebCodecs decoder mishandles a warmup-period CSD blob would silently pass.
For the merge-ready interop test branches: **Caveats — see linked investigation docs:**
- T13's asserting scenario (I7) is in `feat/nests-i7-publisher-reconnect` — when that merges into `claude/cross-stack-interop-test-XAbYB` (or main), this matrix should drop the "in sister branch" qualifier. - Five browser-tier scenarios soft-pass on listener-side
- I6's asserting scenario is in `feat/nests-i6-multi-listener` — same caveat. 0-frame outcomes due to the upstream moq-relay 0.10.x
routing race (`2026-05-07-late-join-catalog-flake-investigation.md`).
Hard floors lined up to land in
`2026-05-07-tighten-cross-stack-assertions.md` once the
routing race is closed.
- Suite-mode runs hit the same race intermittently;
individual-test mode is reliable. CI is intentionally not
wired (`2026-05-07-cross-stack-interop-ci-gating.md`) until
stability is achieved.

**Suite-flake caveats:** the four scenarios marked "(suite-flaky)" hit
moq-relay 0.10.x's per-broadcast subscribe-routing race when run
alongside other scenarios in one JVM. Each passes individually.
Documented + investigation roadmap in
`2026-05-07-late-join-catalog-flake-investigation.md` and
`2026-05-07-moq-relay-routing-investigation.md`. Test code soft-passes
listener-side assertions on 0-frame outcomes to avoid masking the real
upstream issue with looser thresholds; the soft-passes are scheduled
to be replaced with hard floors in
`2026-05-07-tighten-cross-stack-assertions.md` once the upstream race
is closed.

local relay's per-stream byte cliff).

the spec at `nestsClient/plans/2026-05-06-phase4-browser-harness.md`. job) was originally added in commit `c79a3ffa8` but later removed
per maintainer ask in commit `b94737de7` ("don't add these tests
to the build.yml for now"); see
`2026-05-07-cross-stack-interop-ci-gating.md` for the path to
re-wiring.
**Browser harness location:** `nestsClient/tests/browser-interop/`
(was originally `nestsClient-browser-interop/` at repo root;
moved to mirror `nestsClient/tests/hang-interop/` layout).
**Final scenario coverage:** I1, I2, I3, I4 (stereo), I5
(hot-swap), I7 (Chromium publisher reconnect), I9 (packet loss),
I13 (long broadcast), I14 (WebCodecs warmup × CSD), I15 (ALPN).

# Plan: Phase 4 — browser-side cross-stack harness (T16) # Plan: Phase 4 — browser-side cross-stack harness (T16)
**Status:** 📋 Spec — ready for implementation. Phase 1–3 of the **Status:** ✅ Landed. Browser harness lives at
T16 cross-stack interop suite landed the Rust path `nestsClient/tests/browser-interop/`; tests are
(`hang-listen` + `hang-publish` against `moq-relay 0.10.x`, `BrowserInteropTest.kt` covering I1, I2, I3, I4 (stereo), I5
seven scenarios green). Phase 4 adds the **browser path**: (hot-swap), I7 (publisher reconnect), I9 (packet loss), I13
headless Chromium running `@moq/watch` (listener) and (long broadcast), I14 (WebCodecs warmup × CSD), I15 (ALPN).
`@moq/publish` (publisher) against the same harness's relay, Companion landed-results doc:
driven from `:nestsClient:jvmTest` via Playwright. `2026-05-06-phase4-browser-harness-results.md`.
The spec text below is preserved for archaeology; some pieces
shifted during implementation:
- `@moq/watch` / `@moq/publish` weren't directly used; the
harness uses `@moq/lite` + `@moq/hang` `Container.Legacy.Consumer/Producer`
because the published `@moq/hang` 0.2.4 didn't expose the
high-level `Container.Consumer` API.
- Cert pinning uses `serverCertificateHashes` not
`--ignore-certificate-errors` because Chromium's flag does
NOT bypass QUIC cert validation.
- Phase 4.C originally deferred I2/I3/I4/I13/I14 — those
subsequently landed, see results doc.

The flake also affects four browser-tier scenarios after the

`chromium_listener_late_join_still_decodes_tail`,
`chromium_publisher_baseline_kotlin_listener_decodes`,
`chromium_publisher_reconnect_kotlin_listener_recovers`, and
intermittently `chromium_listener_long_broadcast_60s_tone_440`.
Browser scenarios soft-pass listener-side assertions on 0-frame
