Summary

Closes three gaps a triage pass verified as not done, after closing #3366 and #3061 and merging #2877 in the same sweep.

claude-fable-5-1 metadata (carries #3293 by @Veritas-7). src/usage/expected-prices.ts on dev asserts an expected price for this model on four surfaces, but neither scripts/model-metadata.source.json nor the anthropic array of src/generated/model-metadata.ts knew it existed — the pricing rows arrived through unrelated commits that happened to touch that file, and #3293 is the only source of the metadata. Pricing without metadata is the wrong half to have. The generated file is regenerated from the source entry rather than hand-edited. Note cacheRead: 0.25, not the 1 that claude-fable-5 carries: Fable 5.1's published cache-hit rate is 0.025x base input.

Adding the jawcode row changes where the price resolves fromsrc/usage/cost.ts prefers an exact provider-bundle row over the expected-price overlay — so the PR's own test update comes with it: source: "expected" becomes source: "jawcode". The resolved cost4 is identical either way; only the provenance label moves.

CREDITS row for #3284 (closes #3431). The Gemini 3.8 Flash Antigravity work by @mdwsk88 landed via #3286 (3d3c4fe26) and #3284 was closed as superseded, so the contributor graph shows nothing. CREDITS.md sets two bars and both are met: it asks for an issue with landing evidence (#3431 is that issue, opened at @Ingwannu's request), and it requires the maintainer's own words rather than diff inference (the quote is verbatim from the #3284 closing comment). Verified independently: 3d3c4fe26 is an ancestor of origin/dev, #3284 is closed and not merged, and src/providers/antigravity-models.ts names gemini-3.8-flash 16 times.

Ultra Fast, opt-in (closes #3429). This one needs care, because it was already decided once. PR #2994 added an ultrafast row to the pinned catalog and was closed unmerged — the picker gained a choice the wire could not honor. That verdict stands, and nothing here synthesizes a catalog row: src/codex/data/upstream-models.json advertises exactly one tier, priority, on every row that has any, so an ultrafast entry would still be fabricated metadata.

What #3429 actually reports is separately true. A caller who supplies service_tier: "ultrafast" themselves gets the request forwarded, and then canonicalFastTierMarker folds it to undefined, fastIntent goes false, and the attempt is logged as fastOutcome: "not-requested" — the record asserting the user asked for nothing. requestLogSpeedLabel returns undefined for the same value, so the Logs speed column stays empty. The proxy was carrying a tier it refused to name.

The fold now maps ultrafast to its own canonical rather than onto priority, which would have been the opposite lie. There is deliberately no canonicalToWire entry, so the attempt lands on unknown instead of a false applied: it was requested, and we cannot confirm it was honored. The ultraFastTier flag follows the fastRows precedent — optional, .catch(false), read with === true, and off deletes the key rather than persisting a false nobody chose.

Codex Set page head. It carried a title, a status line, the Spark toggle and two buttons on one row, with the account actions sitting above the cards they act on. Pause and Refresh move to their own row below the account-mode banner. The embedded Providers surface keeps them inline — it renders a bare .row with no title, so there is nothing to crowd there.

Codex Set head with the actions relocated below

Verification

Focused checks only; the repository-wide suite was not run.

  • bun run typecheck and bun run lint:gui — clean
  • bun run test:changed — 14415 pass / 0 fail across 785 files
  • 408 focused backend tests including the byte-golden default-path guard in fastwire-characterization-routing.test.ts, which is what proves the flag is genuinely OFF by default
  • New: tests/ultrafast-tier-honesty.test.ts (6) and gui/tests/codex-set-actions-relocation.test.ts (6); the existing head-wrap, toast-tone, controller and locale-parity suites stay green
  • pws/codexAuth keys added to all 9 locales
  • Live on an isolated scratch instance (port 10199, separate OPENCODEX_HOME): the head shows only the title and Spark toggle, the two actions render below it, the Ultra Fast toggle reads OFF by default, and enabling it writes ultraFastTier: true to config.json

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

The one new management-route field is a boolean with an explicit typeof guard; no auth, credential, workflow, or release surface is touched.

Three gaps the triage verified as NOT done: the half-shipped fable-5-1 metadata, the missing CREDITS row for #3284, and Ultra Fast.

The Ultra Fast doc carries the finding that shapes the whole phase: upstream-models.json advertises only priority, so there is no ultrafast tier to forward and re-adding the catalog row would reproduce exactly what #2994 was closed for. What is separately true is that a forced ultrafast request is classified not-requested and gets no speed label — an observability lie fixable without advertising anything.
Carries PR #3293 by @Veritas-7, whose metadata half never landed while its
pricing half did.

On dev, src/usage/expected-prices.ts asserts an expected price for
claude-fable-5-1 on four surfaces, but neither scripts/model-metadata.source.json
nor the anthropic array of src/generated/model-metadata.ts knew the model
existed. The pricing rows arrived through unrelated commits that happened to
touch expected-prices.ts; #3293 is the only source of the metadata, and it is
still open. Pricing without metadata is the wrong half to have.

The generated file is regenerated from the source entry rather than hand-edited,
which is what keeps the two consistent:

  ["claude-fable-5-1",1000000,128000,"text,image",1,null,10,50,0.25,12.5]

Note cacheRead 0.25, not the 1 that claude-fable-5 carries: Fable 5.1's published
cache-hit rate is 0.025x base input, which the existing expected-prices rows
already encode.

The PR's own test update comes with it. Adding the jawcode row changes where the
price resolves from — src/usage/cost.ts prefers an exact jawcode provider-bundle
row over the expected-price overlay — so the assertion moves from
source: "expected" to source: "jawcode" with jawcodeProvider: "anthropic", and
the overlay is asserted directly instead of through sourceRef. The resolved
cost4 is identical either way; only the provenance label changes.

Verification: bun run typecheck, bun test ./tests/usage-cost.test.ts (82 pass),
bun run test:changed (10752 pass / 0 fail across 569 files). Repository-wide
suite not run.

Closes the gap issue #3431 opened at @Ingwannu's request.

The Gemini 3.8 Flash Antigravity work first submitted by @mdwsk88 in #3284 landed
on dev via #3286 (3d3c4fe), and #3284 was closed as superseded rather than
merged — so the contributor graph shows nothing. CREDITS.md exists for exactly
that case.

The file sets two bars and both are met. It says "If you find a landing that
belongs on this page, open an issue"; #3431 is that issue. It also says entries
cite the maintainer's own words and are never inferred from diff similarity; the
quoted text is verbatim from @Ingwannu's closing comment on #3284.

Verified independently rather than taken from the issue body: 3d3c4fe is an
ancestor of origin/dev and is the #3286 merge, #3284 is CLOSED and not merged,
and src/providers/antigravity-models.ts on dev names gemini-3.8-flash 16 times,
so the suffix ladder that PR argued for is what shipped.

Verification: bun run privacy:scan passed (it reads CREDITS.md); table renders
with the existing column alignment.
…ut of the page head

Two halves of issue #3429, plus the page-head relief the same surface needed.

PR #2994 added an ultrafast row to the pinned catalog and was closed unmerged:
the picker gained a choice the wire could not honor. That verdict stands and is
why nothing here synthesizes a catalog row. src/codex/data/upstream-models.json
advertises exactly one tier — priority — on every row that has any, so an
ultrafast entry would still be fabricated metadata.

What is separately true is the half #3429 actually reports. A caller who supplies
service_tier: "ultrafast" themselves gets the request forwarded, and then
canonicalFastTierMarker folds it to undefined, fastIntent goes false, and the
attempt is recorded as fastOutcome "not-requested" — the log asserting the user
asked for nothing. requestLogSpeedLabel returns undefined for the same value, so
the Logs speed column stays empty. The proxy was carrying a tier it refused to
name.

canonicalFastTierMarker now folds ultrafast to its own canonical rather than onto
priority, which would have been the opposite lie: claiming a 1.5x Fast tier when
the caller named a different one. There is deliberately no canonicalToWire entry,
so an ultrafast attempt lands on "unknown" instead of a false "applied" — the
truth is that it was requested and we cannot confirm it was honored.

The ultraFastTier flag follows the fastRows precedent exactly: optional, catch(false)
so a malformed hand edit degrades to off, read with === true, and off deletes the
key rather than persisting a false nobody chose. Its dashboard toggle gets the
boolean guard in config-routes.ts that fastRows never needed.

The page head carried a title, a status line, the Spark toggle and two buttons on
one row, with the account actions sitting above the cards they act on. Pause and
Refresh move to their own row below the account-mode banner. The embedded
Providers surface keeps them inline: it renders a bare .row with no title, so
there is nothing to crowd there.

Verification: bun run typecheck, bun run lint:gui, 408 focused backend tests
including the byte-golden default-path guard in fastwire-characterization-routing,
and the GUI head-wrap, toast-tone, controller and locale-parity suites. Live on a
scratch instance: the head shows only the title and Spark toggle, the two actions
render below, the toggle reads OFF by default, and enabling it writes
ultraFastTier: true to config.json. Repository-wide suite not run.

Ultra Fast requests can be reported as downgraded rather than unconfirmed, which can mislead operators reviewing tier behavior. The forwarding behavior remains intact, but the observation result should be corrected.

Explanation

The PR satisfies #3431 by adding the requested CREDITS.md attribution. It only partially satisfies #3429: src/providers/fastwire.ts, src/server/request-log.ts, src/codex/catalog/parsing.ts, and the related UI/configuration preserve operator-supplied ultrafast tiers, but the feature remains default-OFF and does not detect or generate Ultra Fast catalog entries for supported models. Therefore, the requested native availability and default Codex UI workflow are not fully implemented.

Resolution

Implement upstream or account-capability detection and generate or preserve supported ultrafast catalog entries during normal catalog builds and refreshes. Ensure supported models show Ultra Fast without manual catalog edits, while retaining the existing forwarding, logging, and no-false-confirmation behavior.

Full details: Out of Scope Changes check

Explanation

The CREDITS.md change and Ultra Fast implementation are related to #3431 and #3429. The Fable 5.1 metadata changes in scripts/model-metadata.source.json, src/usage/expected-prices.ts, and tests/usage-cost.test.ts are unrelated to the provided linked issues. The Codex account action relocation in gui/src/components/CodexAccountPool.tsx, gui/src/components/codex-account-pool-main-card.tsx, gui/tests/codex-set-actions-relocation.test.ts, and gui/src/styles.css is also not required by either linked issue. Related planning documents for the Fable gap are out of scope for these linked issues.

Comment @coderabbitai help to get the list of available commands.

Self-review caught the flag stored but never read: `grep ultraFastTier src/`
outside config/types/routes returned nothing, so the toggle persisted a
preference and changed no behavior. Shipping a switch whose description promises
the tier survives regeneration, while nothing consumes it, would be the #2994
failure in a new place — a control that implies an effect it does not have.

normalizeRoutedCatalogEntry now consults the flag. With it OFF the four deletes
run exactly as before. With it ON the row keeps an ultrafast the OPERATOR put in
their own catalog, which is the reported symptom: #3429's reporter hand-edited
opencodex-catalog.json and watched every regeneration delete it.

Preserving is narrowed, not blanket. retainOnlyUltraFastTier keeps the ultrafast
entry and drops everything else, because routed rows are stripped precisely so a
clone of a native template cannot inherit OpenAI's priority tier — reopening that
under an unrelated flag would be a worse bug than the one being fixed. A
service_tier or default_service_tier naming a tier the row no longer carries is
dropped for the same reason. And a row carrying only upstream's Fast is still
stripped with the flag ON: there is no ultrafast to preserve, and inventing one
is the line #2994 was closed for.

The flag is read through ultraFastTierEnabled(loadConfig()) inside parsing.ts
rather than threaded through deriveEntry. That function and its five call sites
are pure RawEntry -> RawEntry transforms with no config parameter; plumbing one
boolean through all of them would be a far larger change than the behavior it
gates. Callers holding a config can still pass opts.ultraFastTier explicitly,
which is what the new tests do, and a read failure degrades to OFF.

Four new tests cover both states, including the two refusals: the flag never
smuggles Fast onto a routed row, and it invents nothing when the operator
supplied nothing.

Verification: bun run typecheck, bun run lint:gui, 340 focused catalog/fastwire
tests including the byte golden, 10 in ultrafast-tier-honesty, and
bun run test:changed at 14419 pass / 0 fail across 785 files.

P1 Badge Preserve ultrafast through the tier decision

For a classified OpenAI service-tier route with fastMode unset, returning "ultrafast" here makes decideTier look up policy.fastWire.canonicalToWire.ultrafast; the default wire only maps priority, so the decision becomes drop and the forwarded request loses service_tier. Before this change, ultrafast was treated as a foreign tier and forwarded verbatim under the default foreignCallerTiers: "verbatim" policy. Separate observability recognition from canonical wire mapping, or explicitly preserve an unmapped recognized tier, and add a serialized-request regression test.

P1 Badge Connect the Ultra Fast setting to catalog generation

When an operator enables this toggle and later regenerates or synchronizes the Codex catalog, the request only persists ultraFastTier; repo-wide references show that no catalog loader, merger, or normalizer reads the field. Consequently, the catalog continues to discard the operator's custom ultrafast tier while the UI reports a successful opt-in. Thread the setting into the catalog generation path and test both enabled preservation and disabled stripping.

Thread ultraFastTier into catalog normalization

The management API can enable config.ultraFastTier, but catalog regeneration never reads it. Fresh routed entries still call normalizeRoutedCatalogEntry, which unconditionally deletes service_tier, service_tiers, default_service_tier, and additional_speed_tiers. A regeneration can therefore replace a hand-configured routed row and remove its service_tier: "ultrafast" metadata. Pass config.ultraFastTier === true into this normalization path and preserve Ultra Fast metadata only when enabled.

In `@src/config.ts` around lines 1056 - 1058, Thread config.ultraFastTier through
catalog regeneration into normalizeRoutedCatalogEntry, passing whether it is
explicitly true; update normalization to preserve service_tier, service_tiers,
default_service_tier, and additional_speed_tiers only when Ultra Fast is
enabled, while retaining the current deletion behavior otherwise.

Comment thread src/providers/fastwire.ts
Adversarial review found that the previous commit made the reported problem
worse, and that every suite still passed while it did.

Recognising ultrafast as a canonical marker routed it into the canonical-wire
lookup in decideTier. That lookup is keyed by canonicalToWire, which maps only
priority, so an unmapped canonical fell straight through to { kind: "drop" }.
Measured before and after:

  before   ultrafast -> forward-caller   wire service_tier=ultrafast
  after    ultrafast -> drop             wire service_tier=(absent)

So recognition was strictly worse than leaving the tier unrecognised: it used to
be a foreign tier, and foreignCallerTiers "verbatim" forwarded it untouched. The
operator's hand-configured tier stopped reaching the provider entirely, and the
new "ultrafast" speed label became unreachable on the Responses path because
tierValueAfterDecision had already cleared the value. That is the exact symptom
#3429 reported, reintroduced by the fix for it.

An unmapped canonical now falls through to the foreign-tier rules rather than
dropping.

Second finding, same root cause: callerCanonicalFast was widened to "any marker",
which made a fastMode:false request from an ultrafast caller record
callerFastSuppressedByConfig. The Fast toggle did not suppress a 1.5x Fast
request; it turned away a differently-named one. The predicate is back to
=== "priority" for the drop/suppression facts, and only fastIntent carries the
wider fast-family question.

Third: ultraFastTierOptIn called loadConfig() per catalog row, and
normalizeRoutedCatalogEntry runs in a per-entry sync loop — that is a chmod, three
secret hardenings, a file read and a full Zod parse per row. It is memoized with a
5s TTL plus a reset seam; callers holding a config still pass opts.ultraFastTier
and bypass it entirely.

Fourth: the expected-prices comment claiming claude-fable-5-1 has no jawcode row
was made stale by 21cb149, which added exactly that row.

Five new tests cover what the previous suite could not see: the wire decision
itself, and the suppression-vs-dropped distinction. The old tests all passed
against the broken behavior because none of them asserted decideTier.

Verification: bun run typecheck, bun run lint:gui, 720 focused fastwire/catalog/
request-log/usage tests, and bun run test:changed at 14466 pass / 0 fail across
787 files.

Adversarial review found a blocker that inverted this PR's central claim, and it was right. Fixed in f626a12da.

BLOCKER — accepted. Recognising ultrafast as a canonical marker routed it into the canonicalToWire lookup, which maps only priority, so the unmapped canonical fell through to { kind: "drop" }. Reproduced directly before fixing:

before   ultrafast -> forward-caller   wire service_tier=ultrafast
after    ultrafast -> drop             wire service_tier=(absent)

Recognition was strictly worse than leaving the tier unrecognised — it used to be a foreign tier and foreignCallerTiers: "verbatim" forwarded it. An unmapped canonical now falls through to the foreign-tier rules. The reviewer's note that this also made the new speed label unreachable on the Responses path (because tierValueAfterDecision had already cleared the value) is correct and follows from the same defect.

MAJOR 2 — accepted. Widening callerCanonicalFast to "any marker" made a fastMode: false request from an ultrafast caller record callerFastSuppressedByConfig. The Fast toggle did not suppress a Fast request; it turned away a differently-named one. Back to === "priority" for the drop/suppression predicates; only fastIntent carries the wider question.

MAJOR 3 — accepted. loadConfig() per catalog row is a chmod, three secret hardenings, a read and a full Zod parse inside a per-entry loop. Memoized with a 5s TTL and a reset seam; callers holding a config still pass opts.ultraFastTier and bypass it.

MINOR 4 — accepted. The expected-prices.ts comment was made stale by 21cb149d5.

The sharpest part of the review was not any single finding but this: "every listed suite passes while the wire behavior is inverted." The old tests exercised canonicalFastTierMarker and requestLogSpeedLabel in isolation and never decideTier, so they could not see it. Five new tests now assert the wire decision itself and the suppressed-vs-dropped distinction.

Re-verified: bun run typecheck, bun run lint:gui, 720 focused fastwire/catalog/request-log/usage tests, and bun run test:changed at 14466 pass / 0 fail across 787 files.

리뷰 · 우선순위 74 / 80

이 PR은 지금 dev(HEAD 00834d710, #3474까지) 위에서 트리아지가 아직 안 끝난 줄 알았던 세 구멍을 한꺼번에 메웁니다. 첫째는 claude-fable-5-1입니다. 이미 src/usage/expected-prices.ts에는 Anthropic / anthropic-apikey / Cursor 네 표면에 가격이 들어 있는데, scripts/model-metadata.source.json과 그걸로 만드는 src/generated/model-metadata.ts의 anthropic 배열에는 모델 자체가 없었습니다. 가격만 있고 메타데이터가 없는 상태가 잘못된 반쪽이라서, 이 PR은 #3293(@Veritas-7)이 가져온 메타데이터 반쪽을 source에 넣고 생성 파일을 다시 뽑습니다. cacheRead는 0.25(공식 0.025x)이고, jawcode 행이 생기면 src/usage/cost.ts가 expected overlay보다 그 행을 먼저 쓰므로 테스트의 source"expected"에서 "jawcode"로 바뀝니다. 숫자 자체는 같습니다.

둘째는 CREDITS입니다. @mdwsk88의 Gemini 3.8 Flash Antigravity 작업(#3284)은 #3286(3d3c4fe26)으로 dev에 들어갔고 #3284는 superseded로 닫혀서 기여자 그래프에 안 남았습니다. CREDITS.md가 요구하는 두 조건(이슈로 기록 #3431, 메인테이너 본문 인용)을 그대로 지켜 한 줄을 넣습니다. 셋째는 Ultra Fast입니다. #2994처럼 카탈로그에 ultrafast 행을 새로 만들어 광고하지는 않습니다. upstream-models.json이 광고하는 티어는 priority뿐이기 때문입니다. 대신 운영자가 자기 카탈로그에 써 둔 ultrafast가 재생성을 버티게 하고(ultraFastTier 옵트인, 기본 OFF), 요청 경로가 그걸 "not-requested"로 거짓말하지 않게 고칩니다. canonicalFastTierMarker는 intent로 인식하되 canonicalToWire에는 안 넣어서 확인 불가는 unknown으로 남기고, decideTier는 매핑 없는 canonical을 drop하지 않고 foreign verbatim으로 넘깁니다(이전 커밋이 drop으로 악화시킨 걸 f626a12da에서 되돌림). Codex Set 헤더의 Pause/Refresh를 계정 배너 아래로 옮긴 UI도 같이 갑니다.

라인 src/providers/fastwire.ts canonicalFastTierMarker / decideTier - 인식과 와이어 매핑을 분리한 설계는 #2994 판결을 지키면서 #3429 관측 구멍도 막습니다. 다만 requestLogSpeedLabel은 플래그 OFF여도 ultrafast를 라벨합니다(의도: 관측 vs 기능 게이트). 기본 OFF 사용자 Logs에 낯선 라벨이 보일 수 있습니다.
라인 src/codex/catalog/parsing.ts ultraFastTierOptIn - loadConfig()를 카탈로그 정규화 경로에서 읽고 5초 TTL로 메모합니다. 토글 직후 5초 안·카탈로그 재빌드 전에는 옛 값이 남을 수 있습니다. 테스트용 resetUltraFastTierOptInCache는 있습니다.
라인 src/codex/catalog/parsing.ts retainOnlyUltraFastTier - 플래그 ON이어도 Fast/priority를 라우티드 행에 절대 실어 보내지 않는 좁힌 보존은 #2994 재발을 막습니다. 운영자가 ultrafast만 넣은 행이 맞는지 한 번 더 확인하면 좋습니다.
경로 CREDITS.md / #3431 - 인용·랜딩 커밋·superseded 관계는 본문과 맞습니다. 머지 후 #3431·#3429 자동 클로즈는 본문에 걸려 있습니다.
경로 #3293 - 이 PR이 메타데이터 반쪽을 나르지만 #3293은 아직 OPEN입니다. 머지 직후 Landed via #3478 + landed-via-maintainer로 닫지 않으면 leftover가 또 남습니다.
경로 GUI Codex Set 헤드 재배치 - 세 구멍 클로저와 직접 축은 다르지만, Ultra Fast 토글이 들어가는 화면이라 같은 PR에 묶인 이유는 읽힙니다. CI는 hygiene/gates/test 1–2 등 통과 중이고 macos·test 3/4는 아직 pending입니다.

메인테이너의 판단이 필요한 지점

  • Logs가 플래그 OFF에서도 ultrafast 라벨을 보여줄지, 아니면 플래그 ON일 때만 라벨할지
  • #3293을 이 PR 머지와 동시에 landed-via로 닫을지(추천: 닫기)
  • Codex Set 헤드 재배치를 이 PR에 그대로 둘지, Ultra Fast만 남기고 UI는 따로 뗄지(지금 상태면 그대로 둬도 됨)
  • CI(macos / test 3–4)가 전부 초록이 된 뒤에만 머지할지

너의 추천
CI가 전부 초록이면 dev에 머지하세요. 세 구멍 모두 현재 dev 방향(카탈로그 정직함, Fable 5.1 가격/메타 정렬, CREDITS 위생)과 맞고, Ultra Fast는 #2994를 다시 열지 않으면서 #3429만 고칩니다. 머지 직후 #3293에 Landed via #3478 at <merge-sha> 댓글 + landed-via-maintainer 라벨 후 닫고, #3429·#3431 클로즈를 확인하세요.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep forwarded ultrafast requests unknown.

In src/providers/fastwire.ts:365, decideTier forwards inherited ultrafast, and the adapter emits it unchanged. Because only priority is mapped, effectiveFastRequested is false. callerFastFamilyIntent is true, so the next branch records fastOutcome and confirmation as "downgraded". Response observation cannot confirm this tier.

Treat an unmapped forward-caller decision as unknown. Keep the fastMode: false drop path unchanged: it must remove service_tier and retain its existing dropped-request metadata. Add regression assertions for the forwarded wire value and both "unknown" fields.

Closes out devlog/_plan/260904_triage_gap_closure with what actually shipped and
the landing SHAs: PR #3478 (3a9c4d2) carried all three gaps, and #3293, #3431
and #3429 are closed citing it.

The part worth keeping is the review round. The first Ultra Fast implementation
passed every suite and was wrong: recognising ultrafast as a canonical marker
routed it into decideTier's canonicalToWire lookup, which maps only priority, so
an unmapped canonical fell through to drop and the tier stopped reaching the
provider — where previously, as a foreign tier, it was forwarded verbatim.
Recognition made the reported problem worse.

Every listed suite stayed green because they unit-tested the two edited functions
in isolation and never asserted the wire decision, and the byte golden pins
catalog bytes rather than the caller routing path. Two lessons recorded: a test
of the functions you edited is not a test of the behavior you changed, and
widening a predicate that serves three questions silently changes the other two.

Also records what was deliberately NOT done — Ultra Fast is still absent from the
model picker, because upstream advertises only priority and a catalog row would
offer a speed the wire cannot deliver, which is what PR #2994 was closed for.

This document describes carried work whose code already landed in #3478 with the
trailer. Repeating it here keeps the contributor graph correct for a body that
names #3293 as carried.
