fix(deepseek): route legacy Flash names to deepseek-flash and price them at Flash rates

DeepSeek's pricing page (https://api-docs.deepseek.com/quick_start/pricing,
re-fetched 2026-10-17) now lists only deepseek-flash and deepseek-v4-pro.
Footnote 1 reads: "Use deepseek-flash as the model name. The legacy names
deepseek-v4-flash and deepseek-v4-flash-vision-exp are still accepted, but
the corresponding models have been retired, their requests are served by
the DeepSeek-V4.1-Flash model and billed at the Flash price." The
2026-09-10 entry on https://api-docs.deepseek.com/updates calls that
routing temporary. Codewhale still sent the retired name in several places
and priced it at the old V4 Flash rates.

Routing (catalog_corrections.json is the owner; the seed was re-rendered
with `scripts/catalog_models_dev.py seed render`):
- DEEPSEEK_ALIAS_REPLACEMENT, the rewrite target for deepseek-chat and
  deepseek-reasoner, is now deepseek-flash.
- The flash, deepseek-v4flash, flash-vision and deepseek-v4flashvisionexp
  shorthands select deepseek-flash.
- official_deepseek_aliases gains deepseek-flash, deepseek-ai/deepseek-flash
  and deepseek/deepseek-flash. The v4-flash spellings are kept and still
  resolve to deepseek-v4-flash, because aggregators use that table and
  still host the V4 Flash weights.
- The ModelRegistry selections (app-server /v1/chat/completions) restated
  the same rule: deepseek-chat, deepseek-reasoner, deepseek-r1/v3/v3.2 and
  the vision shorthands now live on a deepseek-flash row instead of the
  deepseek-v4-flash and vision-exp rows.
- codewhale-config's deepseek_family_model_id no longer hard-codes a second
  copy of the shorthand map; it reads canonical_model_name from the catalog.
- `codewhale model set` (crates/cli canonical_model_for_set) drops its own
  copy of that map and reads the same catalog group, so `model set flash`
  and `model set flash-vision` write deepseek-flash. `/provider <host>
  flash` (commands/groups/core/provider.rs) writes deepseek-flash for the
  flash and v4-flash shorthands. Both now agree with `model = "flash"` and
  `/model flash`.
- auto_model FLASH_MODEL, the DeepSeek router cheap tier
  (RouterCandidates::deepseek) and the inventory's inert router label are
  deepseek-flash, so the subagent Faster lane on DeepSeek picks it too.
- Because "flash" now canonicalizes to deepseek-flash, the per-provider
  wire maps (tui model_for_provider and config normalize_model_for_provider)
  map deepseek-flash to each host's V4 Flash id, as they already do for
  deepseek-chat. Without that, `model = "flash"` on NVIDIA NIM, Novita,
  SiliconFlow, SGLang, vLLM or DeepInfra would have sent deepseek-flash and
  failed. Fireworks gets the same arm: deepseek-flash is sent as
  deepseek-v4-flash, the id Codewhale sent for "flash" there before, and
  fireworks_bundled_fallback_pricing prices it at the hosted V4 Flash rate
  it had before. Wanjie Ark and Volcengine, the other hosts in the
  canonicalization list, pass model ids through unchanged, so they have
  no wire arm to add.
- provider_capability treats every official DeepSeek alias as a 1M,
  thinking-capable route, instead of comparing against
  DEEPSEEK_ALIAS_REPLACEMENT, so deepseek-v4-flash keeps its caps now that
  the replacement constant changed.

Pricing (crates/tui/src/pricing.rs):
- deepseek-v4-flash is priced at the deepseek-flash rates ($0.003 hit,
  $0.15 miss, $0.60 output per 1M off-peak, doubled at peak) from
  2026-09-10 04:00 UTC, the effective time the deepseek-flash doc comment
  already records. Earlier turns keep the V4 Flash rates they were billed
  at, so the existing 2026-08-17 rate tests stay as they are.
- deepseek-flash is priced through the same time-aware lookup. A turn
  recorded before 2026-09-10 04:00 UTC under a shorthand that now resolves
  to deepseek-flash (flash, deepseek-v4flash) was sent as
  deepseek-v4-flash, since deepseek-flash did not exist yet, so it keeps the
  V4 Flash rates it was billed at instead of being repriced at Flash rates.
- deepseek-v4-flash-vision-exp had no price; it is priced the same way from
  that instant and stays unpriced before it. It joins the first-party
  provider-owned allowlist. A pre-2026-09-10 turn recorded under
  flash-vision or deepseek-v4flashvisionexp was sent as the vision id, so
  the direct-route audit prices it as that id and it stays unpriced, as it
  was before this commit.
- deepseek_time_tier now derives from the same time-aware lookup as
  pricing_for_model_at instead of a second hand-written id list, so the
  peak/off-peak chip and the receipt cannot disagree.
- Pre-retirement deepseek-chat/deepseek-reasoner turns are priced as
  deepseek-v4-flash at their recorded time, the model that served them
  before 2026-07-24. Pricing them via DEEPSEEK_ALIAS_REPLACEMENT would have
  repriced those historical turns at Flash rates that did not exist yet.

Copy: the deepseek-chat/reasoner deprecation notice now says DeepSeek
retired the alias and names deepseek-flash. The Auto network hint names
DeepSeek / deepseek-flash in all 15 locale packs, and the /router custom
help example writes model = "deepseek-flash", matching the Fast preset.
docs/CONFIGURATION.md, docs/PROVIDERS.md, docs/GUIDE.md and their
zh_hans copies say the same; the PROVIDERS.md DeepSeek row no longer
lists flash-vision and deepseek-v4flashvisionexp as aliases of the vision
id. The CHANGELOG gets one [Unreleased] bullet, synced with
scripts/sync-changelog.sh.

Existing tests updated because they encoded the old ids: config/tests.rs
(shorthand and deprecation replacement), lib.rs capability report,
model_routing.rs (cheap tier, classifier label, decision selection),
scorecard.rs (chat-alias pricing comparison), tools/subagent/tests.rs
(three Faster route assertions plus the Scout row of the route matrix),
fleet/scout.rs (DeepSeek scout companion), tui/views/router_setup.rs (Fast
preset model), commands/groups/core/provider.rs (seven flash-shorthand
switch assertions, now deepseek-flash), agent lib.rs (vision alias and
reasoner resolution), app-server chat_completions.rs (retired alias
target), cli lib.rs model_set_canonicalizes_deepseek_vision_aliases (the
vision shorthands now write deepseek-flash), and the reviewed.rs selection
count (175 -> 176). scorecard.rs
direct_deepseek_compact_aliases_use_canonical_pricing and the pricing.rs
alias table are unchanged from the parent commit: a 2026-08-17 "flash" turn
still costs what a deepseek-v4-flash turn cost that day.

Known limits, not changed here:
- An explicit deepseek-v4-flash or deepseek-v4-flash-vision-exp on the
  direct DeepSeek route is still sent as typed. DeepSeek accepts both today
  and they are priced correctly, but they break when DeepSeek ends the
  temporary routing.
- The prefixed compact spellings deepseek/deepseek-v4flash and
  deepseek-ai/deepseek-v4flash still resolve to deepseek-v4-flash on the
  direct route, while bare deepseek-v4flash resolves to deepseek-flash.
- On a host whose wire map does not know deepseek-flash, `model set flash`
  and `/provider <host> flash` now write deepseek-flash where they wrote
  deepseek-v4-flash. OpenCode Go's roster has no deepseek-flash, so
  `/provider opencode-go flash` is now rejected as an invalid model; pass-
  through hosts such as Ollama or OpenModel receive deepseek-flash as
  typed. Use the host's own id there. By reading the resolvers (not run),
  `model = "flash"` and `/model flash` do not resolve to a Go model either.
- An explicit deepseek-flash on an aggregator is sent as that host's V4
  Flash model, which is not the V4.1 Flash DeepSeek serves; the receipt
  shows the wire id.
- The Chinese-holiday off-peak rule and Search/Fetch per-request billing
  are separate slices.

Verification. Source 15f1804fe8 plus this diff. The fix-first review
changes (historical shorthand pricing, CLI and /provider shorthands,
Fireworks, PROVIDERS.md rows) were verified on the final tree:
- scripts/dev-test.sh config: 800 tests run, 800 passed, 1 skipped.
- scripts/dev-test.sh cli: 501 tests run, 501 passed, 0 skipped
  (includes tests::model_set_canonicalizes_deepseek_vision_aliases and
  both model_set route tests).
- scripts/dev-test.sh tui pricing scorecard model_routing provider
  config::tests: 1392 tests run, 1392 passed, 13959 skipped. That set
  includes scorecard::tests::direct_deepseek_compact_aliases_use_canonical_pricing,
  pricing::tests::deepseek_pricing_requires_exact_ids_or_explicit_route_aliases,
  pricing::tests::hosted_flash_and_pro_routes_price_from_bundled_docs_rates,
  config::tests::fireworks_flash_alias_is_not_mapped_to_undocumented_model
  and the seven provider.rs flash-switch tests.
- A throwaway probe test, run once and deleted before this commit (1
  passed), checked on DeepSeek and DeepSeek Anthropic: flash-vision,
  deepseek-v4flashvisionexp and the vision id are unpriced on 2026-08-17
  and priced like deepseek-flash on 2026-09-21; flash, deepseek-v4flash,
  DEEPSEEK-V4FLASH and deepseek-flash on 2026-08-17 cost the same as
  deepseek-v4-flash. On Fireworks, "flash" and "deepseek-flash" price at
  $0.14 per 1M input and go on the wire as deepseek-v4-flash.
- CI-form clippy -p codewhale-config -p codewhale-cli -p codewhale-tui
  --all-targets --all-features --locked -- -D warnings (with the three -A
  allows): exit 0, no warnings.
- cargo fmt --all -- --check: clean.
- scripts/sync-changelog.sh and scripts/release/check-versions.sh: ok
  (Version state OK, workspace 0.10.2).
Earlier runs on this slice before the review fixes, not repeated because
those fixes touch none of these crates' sources except the one Fireworks
arm in codewhale-config, which is covered above:
- scripts/dev-test.sh agent: 70 passed; app-server: 177 passed;
  cargo test -p codewhale-localization --lib: 54 passed; CI-form clippy for
  codewhale-agent, codewhale-app-server and codewhale-localization: clean.
- scripts/dev-test.sh tui (full lib suite): 15326 run, 15323 passed,
  3 failed, 25 skipped. The 3 failures are
  tools::test_runner::tests::{run_tests_succeeds_on_fresh_project,
  run_tests_reports_failures_without_hard_error,
  run_tests_cwd_scopes_cargo_to_subdir}: the nested `cargo test` they spawn
  fails with "Operation not permitted (os error 1)" creating a directory
  under /Volumes/VIXinSSD/cw-build-cache/build, also outside the agent
  sandbox. test_runner.rs has no model or pricing code. Not re-verified at
  the parent commit.
- python3 scripts/catalog_models_dev.py seed render --check: ok;
  python3 scripts/check-provider-registry.py: passed;
  python3 -m pytest scripts/catalog_models_dev_test.py: 18 passed. The
  catalog JSON did not change in the review fixes.
- Not run: feature_registry (no docs/features.toml row changed). Not
  regenerated: web/data/agent-docs.generated.json. `node
  web/scripts/check-facts.mjs` already reported it stale at 15f1804fe8,
  before this slice, and these doc edits add to that drift.
- No live DeepSeek or Fireworks request was made; routing and pricing are
  proven by local tests only.

 ## [Unreleased]
 
+- Direct DeepSeek routes now send `deepseek-flash` for `deepseek-chat`,
+  `deepseek-reasoner`, the `flash`, `deepseek-v4flash`, `flash-vision` and
+  `deepseek-v4flashvisionexp` shorthands, and the Auto router's fast tier.
+  `codewhale model set` and `/provider` now write `deepseek-flash` for those
+  shorthands too, matching what `model = "flash"` and `/model flash` resolve
+  to.
+  DeepSeek has retired the V4 Flash and V4 Flash vision models. It still
+  accepts `deepseek-v4-flash` and `deepseek-v4-flash-vision-exp`, but serves
+  them with V4.1 Flash, bills them at the Flash price, and calls that routing
+  temporary. Turns on either name from 2026-09-10 04:00 UTC are now priced at
+  the Flash rates ($0.003 cache hit, $0.15 cache miss, $0.60 output per
+  million tokens off-peak, doubled at peak) instead of the old V4 Flash rates,
+  which overstated a cache hit by about 2.3 times. The vision name was not
+  priced at all before. Earlier turns keep the rates they were billed at,
+  including turns recorded under a shorthand. On NVIDIA NIM, OpenRouter,
+  Novita, Fireworks, SiliconFlow, SGLang, vLLM, DeepInfra and Together,
+  `deepseek-flash` selects that host's V4 Flash model, so the `flash`
+  shorthand keeps working there.
 - When a `tool_search` activation pushes an earlier deferred tool out of the
   bounded conversation toolbox (8 tools, 16 KiB of schemas), the search
   result now names it under `evicted_tool_references`. Before, the tool

When unset, every Chat Completions route uses `separate_field` (Mistral's first-party route uses its typed thinking blocks); set `none` only for a gateway that streams its answer inside `reasoning_content`.
 - `[providers.<name>.auth]` (table, optional): provider-scoped auth source metadata. `source = "command"` stores a command argv plus optional `timeout_ms`; `source = "secret"` stores a `secret_id`. This slice lets provider readiness, `/provider`, and doctor JSON report the auth source class without exposing command argv output or secret values; executing commands and resolving external secret material is handled by the follow-up resolver work.
 - `insecure_skip_tls_verify` (bool, optional provider-table key): legacy compatibility key, disabled by default. When true on the active provider table, provider clients reject the configuration instead of skipping TLS certificate verification.

DeepSeek has also retired the `deepseek-v4-flash` and `deepseek-v4-flash-vision-exp` models: it still accepts both names, serves them with V4.1 Flash, and bills them at the `deepseek-flash` price, which Codewhale applies to turns from 2026-09-10 04:00 UTC.

The exact Kimi Code endpoint recognizes bare `k3` for K3 and `kimi-for-coding` for K2.7; those membership IDs are distinct from the direct Moonshot IDs and are never rewritten across routes. Direct MiniMax recognizes `MiniMax-M3` and the documented M2.x chat model IDs; direct Z.ai recognizes `GLM-5.3` (the default), `GLM-5.2`, `GLM-5.1`, and `GLM-5-Turbo`, and OpenRouter recognizes the matching `z-ai/glm-5.1`, `z-ai/glm-5.2`, `z-ai/glm-5.3`, and `z-ai/glm-5-turbo` IDs — `GLM-5.3` has been live on the Z.ai Coding Plan since 2026-08-13; it inherits its catalog metadata from `GLM-5.2` until Z.ai publishes distinct 5.3 numbers and carries no price, and an explicit `GLM-5.2` selection keeps its own id; direct Sakana recognizes `fugu` and `fugu-ultra-20260615`; direct Xiaomi MiMo recognizes chat IDs `mimo-v2.5-pro`, `mimo-v2.5-pro-ultraspeed`, and `mimo-v2.5`, while TTS IDs are selected through `codewhale speech` / `tts`. Generic `openai`, `atlascloud`, `wanjie-ark`, `xiaomi-mimo`, `arcee`, `moonshot`, `minimax`, `openmodel`, `zai`, `stepfun`, `qianfan`, `sakana`, local Ollama, and Ollama Cloud model IDs are passed through unchanged after known aliases are normalized. OpenRouter and SiliconFlow provider configs with a custom `base_url` also preserve explicit model values, which lets OpenAI-compatible gateways accept bare model IDs. Use `/models` or `codewhale models` to discover live IDs from your configured endpoint. `CODEWHALE_MODEL` overrides this for a single process; `DEEPSEEK_MODEL` is the legacy alias.

DeepSeek Platform receives top-level `thinking` / `reasoning_effort` fields. Ollama Cloud's OpenAI-compatible Chat Completions route preserves its documented `none` / `low` / `medium` / `high` / `max` ladder (`off` is sent as `none`; `xhigh` and `ultracode` normalize to `max`). Direct xAI `grok-4.7` and `grok-4.6` on exact `https://api.x.ai/v1` receive top-level `reasoning_effort = "low" | "medium" | "high" | "xhigh"` (the ladder comes from the bundled catalog row; `grok-4.5` maps `xhigh` to `high`, and rows without a documented effort such as `grok-4.3` get no field); Grok reasoning cannot be disabled, so `off` normalizes to `high`, `max`/`ultracode` to `xhigh`, and `auto` leaves the field omitted so xAI's documented default `high` applies. A custom xAI-compatible `base_url` does not inherit that dialect. Direct Moonshot `kimi-k3` on exact `https://api.moonshot.ai/v1` is always-thinking and receives only top-level `reasoning_effort = "low" | "high" | "max"`; `off` normalizes to `low`, and `medium` to `high`. Kimi Code membership `k3` on exact `https://api.kimi.com/coding/v1` instead receives nested `thinking.effort`, and its `off` setting also normalizes to enabled `low`. Normal dispatched `auto` uses Codewhale's auto-reasoning selector and sends a concrete route-normalized tier; only an omitted reasoning setting leaves the provider default in control. Neighboring gateways and model/endpoint combinations retain the generic Moonshot contract. OpenAI Codex normalizes stale `off` to `low` and sends `max` / `ultracode` as Responses `xhigh`. Z.ai receives documented `thinking` controls and treats enabled thinking as the GLM coding high/max lane. NVIDIA NIM receives equivalent settings through `chat_template_kwargs`.
