Rebased onto the current release/v3.8.51 tip as part of a combined provider-retirement/provenance merge batch (Designer Web, Felo Web, Runtime, GPL-derived removal all landed together already). Conflicts resolved:
- `src/shared/constants/providerRetirement.ts`: add/add conflict — combined `felo-web`/`felo` (already-merged) with `qwen-web`/`qw` into one `RUNTIME_RETIRED_PROVIDER_IDS` set, kept both `assertRuntimeProviderAvailable`/`assertRuntimeModelProviderAvailable` helpers.
- `open-sse/config/providers/registry/minimax/web/index.ts`: modify/delete — kept deleted (file is hailuo-web's registry entry, already retired by #11691; this PR's own change to it was just a comment reword on a since-removed target).
- `open-sse/executors/index.ts`, `executorProxy.ts`, `virtualFactory.ts`, `autoStrategy.ts`, `model.ts`, `chat.ts`, `chatHelpers.ts`, `auth.ts`, `src/lib/db/providers.ts`, `reservedProviderPrefixes.ts`: combined the Designer + Runtime (Felo + Qwen) retirement guard calls at each shared chokepoint — compute-once-then-OR pattern, consistent with the prior Designer+Felo combination.
- `src/shared/constants/providers/web-cookie.ts`, `tests/snapshots/provider/translate-path.json`, `tests/snapshots/executors/executor-map.json`: both sides had inserted a different retired provider (qwen-web vs. already-retired raycast/hailuo-web) at the same dict position — resolved by dropping both. `executor-map.json`'s `keyCount` recomputed to 135 (matches actual merged `entries`).
- `tests/unit/chatcore-executor-proxy.test.ts`, `tests/unit/provider-node-reserved-prefix.test.ts`: split into independent Felo/Qwen test blocks (established pattern for coexisting retirement-mechanism tests); recomputed `RESERVED_PREFIX_COUNT` to 398 (Designer+Felo+Qwen tombstones on top of the post-#11691 REGISTRY, verified via direct module evaluation, not hand-derived).
- `config/quality/test-masking-allowlist.json`: additive merge of Qwen's `_deletedWithReplacement` entries alongside Designer's.
- `README.md` + all `docs/i18n/*/README.md` mirrors, `docs/getting-started/FREE-TIERS-GUIDE.md`, `docs/reference/FREE_TIERS.md`, `docs/diagrams/free-tier-budget.svg`, `docs/screenshots/free-tier-budget-card.svg`: recomputed the free-tier catalog counts (447 entries / 440 active / 7 discontinued) from the actual merged `freeModelCatalog.data.ts`, regenerated the budget-card SVG via its real generator (`scripts/research/gen-budget-card-svg.mjs`), and dropped the retired Qwen quick-start row / QWEN MODELS section from every i18n README (identical unlocalized block across all 34 locales).
- Also fixed a duplicate-import merge artifact in `src/lib/db/providers.ts` (`isRuntimeRetiredProviderId` imported twice) caught by `typecheck:core`, and rebaselined `file-size-baseline.json` for the combined retirement-guard growth (`virtualFactory.ts` +3, with justification).
Focused suite green (345/345 across executor-proxy, reserved-prefix, migration-167, qwen-web-retirement, virtual-auto-combo, web-cookie/session, executor-map-golden and siblings), plus `typecheck:core` and `check-file-size`/`check-changelog-integrity` clean. Thanks for the provenance-hold retirement work — appreciated.
* fix(web-tools): anchor tool contract at prompt tail + user-turn reminder
The <tool> contract from prepareToolMessages was prepended as the first
system message. Web executors fold all system messages into one block, so
with agentic clients whose system prompts exceed ~28K chars the contract
sat at the head of a huge block and web models ignored it, refusing tool
calls with "tool X is not in my tool set" (chatgpt-web, 0/3 at 30K chars).
Two changes, both required in testing:
- Dual placement: the full contract now rides as a trailing system
message (folds to the tail of the system block) and a one-line
reminder naming the tools is appended to the latest user message.
- Rewording: the contract now frames injected tools as client tools
invoked via a plain-text protocol, distinct from the model's native
tool registry (web.run, python.exec, ...), and instructs the model to
never claim they are unavailable. Without this the model resolved
tool names against its native registry and refused even when it had
seen the contract.
Measured on cgpt-web gpt-5.5-thinking/gpt-5.6-thinking/o3: prepend 0/3
tool calls at 30K chars; dual placement 16/17 across 30K-250K system
prompts, 30-tool sets, multi-turn tool history, streaming, and 3-way
concurrency, with no spurious calls on no-tool prompts. Known limit:
~40K-char single user messages still flake (2/3) due to the upstream
model's own injection heuristics.
All prepareToolMessages consumers parse system messages
position-independently and select the current user turn by role scan,
so the trailing system message is shape-safe for every web executor.
* test(web-tools): cover contract placement edge cases
