docs(devlog): Gemini 3.8 Flash rollout closeout - #3292
Conversation
…out wp0)
Diff-level roadmap for rolling Gemini 3.8 Flash across every surface that
currently names 3.6/3.7.
Two findings shape the plan, both first-hand rather than inherited from the
3.7 unit:
- Google documents 3.7 Flash as "remains fully supported", and a live CCA
fetchAvailableModels call returns 3.5, 3.6, 3.7 and 3.8 together. So this
is an ADDITIVE rollout with a default move, not the hard replacement the
3.6 to 3.7 migration performed.
- CCA publishes gemini-3.8-flash-{low,medium,high} and no -tiered row, so 3.8
is structurally 3.6-shaped: it belongs in ANTIGRAVITY_EFFORT_WIRE_MAP, not
in the single-wire thinkingLevel map 3.7 uses.
Three adversarial audit rounds (independent gpt-5.6-sol reviewer at high
effort) took this from FAIL to PASS. The two most valuable findings were
confirmed against the live backend: the Claude SDK identity paragraph 429s on
3.8 exactly as on 3.7, so that strip guard must widen before 3.8 becomes the
default; and static vs discovered effort resolution returned different request
bodies for the same input.
Docs only. No runtime change in this commit.
Google shipped Gemini 3.8 Flash on 2026-09-02 and CCA already returns it ranked first in the Recommended sort, but discovery published it as three uncollapsed rows with no effort ladder at all. Additive, not a replacement. The 3.6 generation vanished from CCA the moment 3.7 shipped, which is why RETIRED_FLASH_TIERS exists. 3.8 did not do that: Google documents 3.7 Flash as remaining fully supported, and a live fetchAvailableModels call returns 3.8, 3.7 and 3.6 together. So 3.7 stays picker-visible and every retirement mapping is left where it is. 3.8 tiers ride SUFFIX wire ids, unlike the single -tiered id 3.7 uses, so it is registered through ANTIGRAVITY_EFFORT_WIRE_MAP. Two consequences, each proven against the backend rather than assumed: - The suffix is the sole tier carrier. CCA accepts a -low wire id paired with a HIGH thinking level and returns 200, so a contradictory pair would run at an unknowable tier. ANTIGRAVITY_SUFFIX_TIER_MODELS suppresses the redundant level and makes static resolution byte-identical to the discovery path, which never emitted one. That divergence also swallowed clamped efforts: max/xhigh/ultra resolved differently before and after discovery ran. - The Claude SDK identity paragraph 429s on 3.8 exactly as on 3.7. The strip guard was an equality check on one model id; with 3.8 becoming the default it would have returned RESOURCE_EXHAUSTED for every Claude-Agent-shaped request while looking like a quota problem. Membership is now canonicalized so raw suffix selectors from a partial ladder are covered too. GEMINI_FLASH_WIRE_ID is renamed GEMINI_RETIRED_FLASH_TARGET_WIRE_ID: it holds the 3.7 redirect target, and after 3.8 became current the old name pointed readers at the wrong model. Verification: bun run typecheck, plus focused tests/google-antigravity-wire.test.ts, gemini-37-flash-migration.test.ts, google-adapter.test.ts, provider-registry-parity.test.ts - 166 pass, 0 fail.
Adds the google/gemini-3.8-flash source record (regenerated, never hand- edited) and the Antigravity + direct Google price rows. The source record deliberately omits `cost`. Bundled generated metadata is consulted before the expected-price overlay and returns status "verified", so copying the adjacent 3.6 record - which does carry a cost block - would make the Antigravity row unreachable and report CCA spend as a verified price. Google publishes Developer API prices; it does not publish that Cloud Code Assist charges them. The overlay is verified-derived for exactly that reason: the number is proven, the claim that Antigravity bills it is inferred. GEMINI_38_FLASH is its own constant despite matching 3.7 today, so a later re-verification of one cannot silently move the other. Nothing is retired here. Reconciliation refreshes capability records from the registry, so an existing user picks up 3.8 on the next start, and a user who deliberately chose 3.7 keeps it - Google still serves that model. The new reconcile case asserts that preservation directly; the pre-existing 3.5 case only exercised the opposite branch, where a retired default gets healed. Verification: bun run typecheck, plus focused usage-cost, model-metadata-sync, oauth-provider-reconcile and gemini-37-flash-migration - 137 pass, 0 fail.
Direct Google, the free-provider directory, the Gemini web-search sidecar default, a preemptive Cursor seed, and the sidecar docs row. The direct Google ladder omits `minimal` even though its 3.5/3.6/3.7 neighbours list it: Google documents `minimal` as a validation error for this generation. defaultModel stays gemini-3.5-flash - adding a model elsewhere must not silently move an existing API-key user's default. The free-directory Gemini row gets a row-specific lastVerified rather than a bumped shared constant, which would have stamped a 2026-09-03 check onto every other provider row that nobody re-checked. The Cursor seed follows the documented glm-5.3 precedent: Cursor has not announced 3.8, and the static catalog is intersected with the live roster, so the entry stays invisible until Cursor lists it. Left alone deliberately: GEMINI_DIRECT_WIRE_RENAMES gains no 3.8 entry, because no source anywhere proves a gemini-3.8-flash-tiered id exists, and the providers.md rename example keeps naming 3.7 for the same reason. Verification: bun run typecheck, plus 15 focused test files - 753 pass, 1 fail. The failure is pre-existing and unrelated: 'Antigravity live model discovery uses the CCA agent list' leaks a credential across files and fails on the clean tree too, while passing when that file runs alone.
…not selector The maintainer review found a hole three audit rounds missed, and a live probe confirmed it: a saved gemini-3.6-flash selection does not call 3.6. Rule 0 redirects it onto gemini-3.7-flash-tiered, which rejects the Claude Agent SDK identity paragraph with a 429 that reads as quota exhaustion. The guard keyed on the selector through canonicalAntigravityUsageModel, which covers the collapsed base and the raw suffix rows. It cannot cover retired ids, because those deliberately keep their OWN identity for usage accounting - that is the rule protecting historical spend from being relabelled. Two individually correct mechanisms combined into a gap, and every saved 3.6/3.5 config would have kept 429ing after this rollout. Judging the routed wire id closes it, and naming a wire spelling once now covers every selector that can reach that generation rather than requiring the set to enumerate selectors that redirect into it. The old test asserting a 3.6 selection KEEPS the paragraph was asserting the bug; it is replaced by one proving the strip, plus a real control on claude-sonnet-4-6 - a model with no recorded rejection, where the paragraph is literally true. Also folds the review's second point: the direct google 3.7 row no longer advertises `minimal`. Google documents it as a validation error for that generation, which is the same evidence 3.8 relies on, and the line was already being edited here. 3.5 and 3.6 keep theirs - their pages still list it. Verification: bun run typecheck, plus 12 focused test files - 681 pass, 0 fail.
Records the merge (3d3c4fe), the 25/25 CI rollup on the exact head, and the audit history - including the maintainer-review finding that three adversarial plan rounds missed because it lived in the interaction between two individually correct mechanisms.

When Cursor has no OAuth token, or live discovery fails without a stale cache, provider-fetch.ts returns the configured static seed. Because CURSOR_STATIC_MODELS derives a picker row from every CURSOR_CAPABILITIES entry, this addition advertises gemini-3.8-flash even before Cursor's roster contains it, despite the effort-map comment calling the seed inert; selecting it then emits unsupported gemini-3.8-flash-{low,medium,high} wire IDs. Keep the preemptive routing metadata dormant or gate this picker row on successful live discovery.

Clarify the rollout scope.
Line 12 says every surface that names Gemini 3.6 or 3.7 receives the same rollout. Lines 57-63 exclude GitHub Copilot, while devlog/_plan/260903_gemini_38_rollout/001_vendor_claim_ledger.md Lines 38-39 confirms that Copilot names those models. State that the goal applies only to OpenCodex-maintained surfaces with proven Gemini 3.8 support, or record this evidence-based exception here.

Update the rollout record to match shipped behavior.
This record says that removing minimal from Gemini 3.7 is out of scope. The current implementation and tests now ship ["low", "medium", "high"] for Gemini 3.7. Mark the correction as included, or restore the previous ladder if it is truly out of scope.

Derive the Google model list from the canonical registry.
CONNECTABLE.gemini.models duplicates the Google catalog in src/providers/registry.ts:1739. Adding Gemini 3.8 to both sources creates another drift point. Reuse the canonical registry data, or document and test why this directory must remain independent.
As per path instructions, provider catalog metadata belongs in the canonical provider registry and derivation flow, and provider facts must not be duplicated across independent pickers or seeds.

Use evidence dates that are valid at merge time.
On September 2, 2026, verifiedAt: "2026-09-03" and lastVerified: "2026-09-03" are future-dated, while the rollout records describe the September 3 pricing and live-discovery checks as completed. Record the actual verification date after those checks occur, or mark the evidence pending; do not use verified or verified-derived with a future date.

Await saveCredential before reconciliation. At tests/oauth-provider-reconcile.test.ts:152, the synchronous test starts saveCredential without awaiting it. saveCredential awaits the queued mutateStore operation, which acquires the file lock and persists later, so reconcileOAuthProviders at line 169 can run before setup completes.

Summary
Closeout record for the Gemini 3.8 Flash rollout that merged in #3286. Documentation only — no runtime change.
It records the merge SHA, the 25/25 CI rollup on the exact head, and the audit history, including the maintainer-review finding that three adversarial plan rounds missed. That one is worth keeping: it lived in the interaction between two individually correct mechanisms (retired ids keep their own usage identity to protect historical spend; the paragraph guard keyed on the selector), so neither looked wrong in isolation.
