## Notes

Public signal: IntervalCoach forum #856 added Sick/Injured/Holiday range support.

R001 plan feedback requires a concrete contract before implementation.

Step 3 verification plan: run `make check` (fmt-check, vet, lint, race tests), run `make test` to satisfy the explicit full-suite checkbox, then run `make build` separately. No integration-test target or task-specific integration fixture exists, so the integration checkbox is N/A with this rationale. On any failure, fix it, rerun the narrow failing package/command, then rerun the full verification command set before marking Step 3 complete. Record command outcomes in STATUS.md.

### Step 1 Design Contract

**Public API surface:** add a dedicated core write tool named `add_unavailable_date_range`, rather than extending `add_or_update_event`. Rationale: the range-write contract is intentionally narrower than generic event writes, easier for LLMs to discover, and avoids adding range semantics to a single-date tool. Catalog integration in Step 2 must add the name to `internal/toolcatalog` known + athlete-scoped lists, register it near event writes in `registryBaseTools`, mark it `RequirementWrite`, use `coreTool`, include it in coach per-athlete ACL eligibility, schema snapshots/hash/doc catalog surfaces, README, PRD, and generated/toolcheck expectations.

**Category contract:** accept a closed unavailability set only: `HOLIDAY`, `SICK`, `INJURED`. Normalize by trimming whitespace, uppercasing, and accepting explicit aliases `HOLIDAYS`, `VACATION`, `PTO`, `TIME_OFF`, and `TIME OFF` as `HOLIDAY`; `ILL`, `ILLNESS`, and `SICKNESS` as `SICK`; `INJURY` as `INJURED`. Reject broader words such as `TRAVEL`/`AWAY` and every other category, including `NOTE`, `WORKOUT`, race, fitness, and custom categories, with a short actionable user error. The generic `add_or_update_event` remains pass-through and unchanged.

**Request/response and idempotency contract:** request fields are required `start_date`, `end_date`, `category`; optional `name`, `description`, and `include_full`. Dates are athlete-local inclusive `YYYY-MM-DD`; same-day ranges are allowed; reversed ranges and ranges over 31 inclusive days are rejected. Implementation creates one upstream event per day because `intervals.WriteEventParams` writes a single `Date`. Each write uses normalized `Category`, `Type: "Unavailable"`, default `Name` equal to `Holiday`, `Sick`, or `Injured` when omitted, optional `Description`, and a generated stable `external_id` with prefix `icuvisor-unavailable-v1-` plus the first 24 hex chars of SHA-256 over `category\ndate\nname\ndescription` so identical retries skip but changed marker details get a different key. Pre-existing same-day rows that exactly match writable fields also skip; mixed ranges create missing days and report skipped days. Nonmatching same-day events, including workouts and older unavailable markers with different details, are not overwritten or deleted; they are reported as conflicts/warnings while the unavailable marker is still added unless it is a duplicate. Response shape: `{events:[terse event rows], status:"created|partial|skipped", _meta:{operation:"create_range", date_range:{oldest,newest}, timezone, category, requested_days, created_count, skipped_count, conflict_count, range_cap_days:31, include_full, skipped:[{date,event_id,reason}], same_day_conflicts:[...]}}`; status is `created` only when every requested day created and no conflicts were reported, `partial` when at least one day was created and any requested day was skipped or had conflicts, and `skipped` when no writes were needed because all requested days were duplicates. `include_full:true` only adds raw upstream payloads under event rows as existing event tools do. If an upstream write fails mid-range, the tool does not roll back earlier successful writes; it returns the short user error without structured counts, and the generated external IDs make retrying the same request safe.

**Initial test contract:** Step 1 failing tests should cover valid multi-day creation and write params, alias normalization, repeated-call idempotency, mixed existing/missing days, invalid/reversed/excessive ranges, unsupported categories, include_full shaping, and safety invariants that the tool is `RequirementWrite`/core and does not require delete mode or delete events. Step 2 targeted tests must include `go test ./internal/tools ./internal/mcp ./internal/toolchecks` after schema/catalog updates.
