+# Phase 16 — Retarget miscellaneous specs
+
+**Estimated time:** ~20 minutes
+**Touches:**
+`spec/dispatch/adapter/minimax/model_catalog_spec.rb`,
+`spec/dispatch/adapter/minimax/pricing_table_spec.rb`,
+`spec/dispatch/adapter/minimax/errors_spec.rb`,
+`spec/dispatch/adapter/minimax/strict_fallback_spec.rb`,
+`spec/dispatch/adapter/minimax/http_client_spec.rb`,
+`spec/dispatch/adapter/minimax/rate_limiter_spec.rb`,
+`spec/dispatch/adapter/minimax_spec.rb` (the main top-level spec).
+
+## Goal
+
+Update the remaining smaller specs so the suite passes end to end. Most
+of these are mechanical: rename Claude → MiniMax, update model ids,
+fixture-derived assertions, and remove references to deleted code.
+
+## Pre-reading
+
+Read each file briefly before editing. They are smaller than the chat
+specs from phase 15 — most are 50–200 lines.
+
+## Per-file changes
+
+### model_catalog_spec.rb
+
+- Replace every Claude model id with a MiniMax id (`MiniMax-M2.7`,
+  etc.).
+- Update `supports_vision` assertions: now `false` for all MiniMax
+  models (phase 07).
+- Update `max_context_tokens` assertions: now `204_800` for all 7
+  models.
+- Update pricing assertions: every `*_per_mtok` field is `0.0`.
+- Drop the `"(unrated) #{display_name}"` example (phase 07 dropped
+  that branch).
+- Add a test that `build("MiniMax-M2.7")` returns the right
+  `ModelInfo` shape.
+- Add a test that `build_from_api({"id"=>"MiniMax-M2","display_name"=>"M2"})`
+  uses the display_name as `name`.
+
+### pricing_table_spec.rb
+
+- Replace Anthropic model ids with MiniMax ids.
+- Assert `lookup("MiniMax-M2.7")` returns a `ModelPricing` with all
+  four `*_per_mtok` fields equal to `0.0`.
+- Assert `context_window("MiniMax-M2.7") == 204_800`.
+- Assert `max_output_tokens("MiniMax-M2.7") == 16_384`.
+- Assert `known_ids` is an array of exactly the 7 MiniMax model ids.
+- DELETE any example that asserted real Anthropic price values.
+
+### errors_spec.rb
+
+- Rename `Dispatch::Adapter::ClaudeErrors` references to
+  `Dispatch::Adapter::MiniMaxErrors`.
+- Update `PROVIDER` assertion to `"MiniMax"`.
+- Add a test for the new `parse_message` fallback to top-level
+  `"message"` key (phase 11).
+- Keep the existing tests for status-code → exception mapping (401/403
+  → AuthenticationError, 429 → RateLimitError, 529 → OverloadedError,
+  400/422 → RequestError, 5xx → ServerError, other → Error).
+- The `OverloadedError < RateLimitError` test stays.
+
+### strict_fallback_spec.rb
+
+- Rename `ClaudeErrors` to `MiniMaxErrors` if referenced.
+- Update model ids.
+- Add new examples covering the broadened regex patterns from phase
+  10:
+  - `"compiled grammar too large"` → matches.
+  - `"schema too complex"` → matches.
+  - `"grammar exceeds maximum size"` → matches.
+  - `"tool_schema too large"` → matches.
+  - `"missing required field: messages"` → does NOT match.
+  - Status 429 with grammar message → does NOT match (status guard).
+  - Non-`RequestError` exception → does NOT match.
+
+### http_client_spec.rb
+
+- Rename `ClaudeErrors` to `MiniMaxErrors` if referenced.
+- Replace `https://api.anthropic.com` URLs with
+  `https://api.minimax.io/anthropic`.
+- Drop `claude_code_only` parameter usage if any remains (it should
+  not — phase 04 removed it).
+- Update `Authorization` header expectations to `Bearer <key>`.
+- Drop OAuth-token-refresh-related examples (deleted in phase 02; if
+  any survived, delete them now).
+
+### rate_limiter_spec.rb
+
+- This spec exercises the `RateLimiter` class from
+  `dispatch-adapter-interface`. It probably does NOT have many
+  Claude/MiniMax-specific assertions. Check:
+  - The state file path (was `~/.config/dispatch/claude_rate_limit`,
+    now `~/.config/dispatch/minimax_rate_limit` per phase 02 step 4).
+  - Update path expectations accordingly.
+- Drop any constant references to Claude.
+
+### minimax_spec.rb (the renamed claude_spec.rb)
+
+This is the top-level spec for the public class.
+
+- Rename `Dispatch::Adapter::Claude` → `Dispatch::Adapter::MiniMax`
+  (should already be done by phase 01; verify).
+- Update constructor examples to the new kwargs (`api_key:`,
+  `key_path:`).
+- Add a test that:
+  - Construction with explicit `api_key:` works.
+  - Construction with `ENV["MINIMAX_API_KEY"]` set works (stub via
+    `allow(ENV).to receive(:[]).with("MINIMAX_API_KEY").and_return("k")`).
+  - Construction with neither raises `ArgumentError`.
+- Drop `authenticate!`, `authenticated?`, `logout!`, `usage_report`
+  examples (these methods were deleted in phase 02).
+- Update `DEFAULT_BASE_URL` and `DEFAULT_MODEL` constant assertions.
+
+## Acceptance criteria
+
+- ALL spec files in `spec/dispatch/adapter/minimax/` pass cleanly.
+- `spec/dispatch/adapter/minimax_spec.rb` passes cleanly.
+- No `.skip`, no `.pending` anywhere in the spec suite.
+- `grep -rn 'ClaudeErrors\|api.anthropic.com\|claude-sonnet\|claude-3\|sk-ant-oat\|is_oauth\|proxy_\|claude-cli\|x-stainless\|anthropic-beta\|anthropic-version\|X-Api-Key\|usage_report\|authenticate!\|claude_code_only\|interleaved_thinking\|extra_betas' spec/`
+  returns ZERO matches.
+- `bundle exec rubocop --autocorrect-all` exits 0.
+- `bundle exec rspec` exits 0 with no skipped or pending examples.
+
+## Verification
+
+Run `run_tests` with `project_path=reference/dispatch-adapter-minimax`.
+This is the FIRST phase where the entire test suite must pass cleanly.
+If anything fails, fix the implementation (or the test if and only if
+the test is asserting on something that no longer exists). NEVER
+weaken or skip a test to make it green.
