Summary

Follow-up quests from today's merge batch, planned interactively with the maintainer. Quest-only; no code.

New quests:

Updated:

Decisions

Kotlin abort: where does it live?

  • ✅ m1, fix in the current generator fork and bump the pin
  • Fold into the uniffi hard fork
  • m2

TS same-instance fixture: where?

  • ✅ New test-flakes-2 child
  • Fold into ts-video-content

BBR seeds: where? (first answered m2, re-asked after finding it is a CI #[test], not a benchmark)

  • ✅ test-flakes-2 child, m1
  • m2 [S]
  • Fold into sim-seed

C++ shared FFI artifacts: where?

  • ✅ m1 [M]
  • m0 ci epic child
  • m2

Nightly measurement: how to track?

  • ✅ m0/ci [XS] condition quest
  • Fold into ffi-reuse
  • No quest

read-backfill: settlement window adds startup latency.

#5148 unified auth: unnamed requests are admitted by

  • ✅ the union of session-lifetime auths
  • every live auth
  • the connection credential only

#5148: a named request outside its auth but inside session scope

  • ✅ is refused and ends with its auth
  • is admitted (the name is a hint)

#5148: lite auth=id

  • ✅ spec in lite-07-wip now, under the auth epic (which gates lite-07 finalize)
  • defer to lite-08
  • never

#5148: outgoing request tokens

catalog Consumer: opaque?

  • ✅ Quest it, m1 [S]
  • Leave as-is

🤖 Generated with Claude Code

(Written by Claude Opus 5.5)

Add quests for the Kotlin destroyed-argument abort, the TS same-instance
resume fixture, the seeded BBR marking test, C++ reuse of the shared FFI
build, the Nightly check after FFI reuse, an opaque catalog consumer, and
the two auth steps after #5148. Rewrite read-backfill to take its floor
from reported bounds instead of a settlement window, and record the
confirmed TS compliance cause.

Automated review by review (OpenAI)

Reviewed commit: 903e341.

No actionable bugs found in these plans. The direction is sound: read-backfill now depends on explicit bounds rather than adding startup delay; C++ reuse requires compatibility and installed-consumer proof; Kotlin lifetime repair belongs in the generator; and flake work preserves assertions while requiring reproducible evidence. The auth work follows the linked unified-auth decision and keeps incoming verification, wire naming and outgoing updates separate.

Implementation watchpoint: the new moq-transport auth parameter needs its support/negotiation semantics specified when updating the extension, since current decoders reject unknown request parameters. This is not a demonstrated defect in the planning-only change.

Verification: static review of all changed plans, references and relevant repository code/specs. No tests, builds, CI dispatches or runtime changes executed; the plans do not establish implementation correctness.

Walkthrough

This pull request adds quest entries and planning documents for FFI reuse, request authorization, Kotlin argument handling, catalog consumer opacity, and test-flake investigations. It revises the ordered-read startup plan to use publisher-reported bounds without a settlement wait. It also adds evidence to the TS video-content flake quest.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 903e3

The plans need correction before they guide implementation: ordered reads could omit valid groups, and live requests could lose authorization during renewal. Resolve those contracts and align the affected prerequisites before merging.

Review comments at @quest/m0/ci/README.md:
- Line 60: Update the “Nightly after FFI reuse” entry in the CI README to
include #5527 alongside #5549 as a prerequisite for the Nightly and tag runs,
matching the readiness condition in the linked quest.

Review comments at @quest/m1/auth/request-auth-id.md:
- Around line 17-18: Reconcile the request-token API contracts: at
quest/m1/auth/request-auth-id.md lines 17-18, align the queue decision with
quest/m1/auth/README.md lines 31-32; at quest/m1/auth/request-update.md lines
23-24, revise the setter decision to align with quest/m1/auth/request-token.md
lines 79-86. Update both sites so the required quests consistently specify the
shared `requests()` queue and `add()` rather than incompatible queue and setter
APIs.
- Around line 33-34: Update the lite renewal sequence so the old auth remains
open until a barrier confirms both acceptance of the new auth and application of
the SUBSCRIBE_UPDATE. Only close the old auth after that barrier completes.
- Around line 31-32: Update the unknown-auth-ID wait in the request
authentication flow so it has a defined timeout and releases the request-gate
slot when the wait times out or is canceled. Preserve the existing behavior for
IDs that have arrived or already ended.

Review comments at @quest/m1/auth/request-update.md:
- Line 39: Update the Required list in the Request tokens quest to include the
auth-ID quest as a prerequisite alongside Request tokens, so the Lite path is
not considered ready without its wire contract.

Review comments at @quest/m1/read-backfill.md:
- Line 48: Revise the read-backfill plan’s “Subscribe ranges” guidance: do not
use SUBSCRIBE_OK.Group or SUBSCRIBE_START as the oldest covered group or
ordered-read floor. Use a guaranteed coverage bound that accounts for multiple
or disjoint ranges, so valid groups delivered after subscription resolution are
not discarded.

request-update's lite path to request-auth-id, bound the unknown-ID wait,
flag the lite renewal race, add concept docs, name #5527 in the CI entry,

Reviewed commit: 12e9a6e, against 903e341.

The auth clarifications are sound: requester-local limits bound unknown-ID waits, renewal must confirm application before dropping old auth, and the Lite dependency does not block moq-transport renewal. The concept-documentation checklist and explicit exclusion of SUBSCRIBE_OK.Group address the independent planning feedback.

One new P2 remains in the revised floor algorithm: the prerequisites resolve relative ranges against the latest group, whereas largest() explicitly excludes frameless groups. Computing the range floor from largest() can therefore place the cursor outside the requested range even on Lite (inline). Obtain the publisher's actual resolved bound or reconcile those semantics before implementation.

Verification: static review of the changed plans, range/largest prerequisites and ordered-reader behavior. This is a plan-level contradiction, not a demonstrated regression in currently implemented wire behavior. No tests or builds run.

Reviewed commit: 65beac9.

The publisher-resolved start and frameless-newest-group regression requirements address my previous read-backfill finding. The plan no longer infers the request floor from largest() or SUBSCRIBE_OK.Group.

The subsequent clarifications cover disjoint ranges, the auth-ID boundary, auth/request fan-out benchmarks, independently landing moq-transport documentation, and Lite route renewal through ANNOUNCE_UPDATE. The explicit Route/Subscription message mapping matches the existing protocol shape. Overall, these are focused corrections that preserve the intended dependency split.

No additional actionable issues found in the revised plans. Verification: static inspection of plan changes and relevant protocol definitions through GitHub; no tests or builds run.

Merge summary

Review rounds from Codex and CodeRabbit, all addressed within the recorded decisions; no decision in the PR body changed.

  • Auth quests (request-auth-id.md, request-update.md): both point at feat(auth): a request token is one more auth on requests() #5148's rewrite of request-token.md and the auth README rather than editing them here. Added: at most one token per moq-transport request (distinct refused NOT_SUPPORTED, repeated refused MALFORMED_AUTH_TOKEN); REGISTER names the auth it registers for the carrying request; AUTH ID u64::MAX is refused; the unknown-ID wait spends only the requester's own budget, with no timer; the lite renewal must not race the old auth's drop; a lite Route renews via ANNOUNCE_UPDATE (which gains Auth (i)) and a Subscription via SUBSCRIBE_UPDATE; an auth-fan-out sweep in rs/moq-net/benches/auth.rs; and updates to the doc/concept pages. The moq-transport renewal path needs only Request tokens, and only the lite path follows request-auth-id.md.
  • read-backfill: a relative start's floor is the start the publisher resolved for this request, not largest() or SUBSCRIBE_OK's Group, and a lite-07 field is added through Lite-07 ranges if one is needed. The cursor is range-aware across disjoint ranges, and new tests cover the disjoint-range and frameless-newest-group cases. How each relative boundary is reported is left to implementation.
  • m0/ci: the Nightly entry now names ci: give independent nightly workloads their own jobs #5527 too.

Merged with main; quest check and just check pass.
