 # HoopScout v2
 
-HoopScout v2 has completed its phase-0 workflow foundation and is now using accepted phase-1 decisions to guide implementation planning. The repository remains repository-owned, portable across machines, and explicit about how humans and Codex should work.
+HoopScout v2 is a Django/PostgreSQL scouting application developed through a repository-first workflow. The repo keeps both implementation guidance and Codex collaboration rules in version control so the project stays portable across machines.
 
-The current goal is to maintain:
+## Current MVP
-- Codex-assisted development
-- custom agent usage
-- repeatable task execution
-- repository-owned instructions
-- machine portability
-- branch discipline
-- implementation guidance driven by accepted ADRs
 
-## Current Phase
+The current application baseline provides:
+- containerized local development
+- curated sample seed data for manual exploration
+- player scouting search with player, context, and stat filters
+- wingspan-aware player filtering (`min_wingspan_cm` / `max_wingspan_cm`)
+- matching season/team/competition context on search results
+- result sorting and pagination
+- login/logout with Django built-in authentication
+- user-scoped shortlist favorites
+- user-scoped plain-text scouting notes on player detail pages
+- user-scoped saved searches (save, rerun, delete)
+- first real-data ingestion command baseline (`import_hoopdata_demo_competition`) with idempotent source-identity mapping
+- first public European importer (`import_lba_public_serie_a`) for LBA Serie A player-stat scope with idempotent external-ID binding
 
-Phase 0 established the working method for the repository. Phase 1 has already added accepted technical decisions for:
+Accepted technical and product-shaping decisions live in:
-- architecture principles
-- technical decision process
-- runtime and development stack
-- initial project structure
-- containerized developer workflow
-- configuration and environment strategy
-
-Current work should follow those accepted decisions rather than re-deciding them informally.
-
-## Workflow Foundation
-
-The repository still depends on the phase-0 foundation for:
-- repository workflow
-- branch policy
-- Codex project configuration
-- agent roles
-- reusable task-closeout behavior
-- machine setup guidance
-- documentation discipline
-
-Key decision references:
 - `docs/ARCHITECTURE.md`
 - `docs/ARCHITECTURE_PRINCIPLES.md`
 - `docs/DECISION_PROCESS.md`

+## Local Development
-- `.editorconfig` provides shared formatting defaults.
+
-- `.gitignore` defines ignored files for the repository.
+1. Start the stack with `docker compose --env-file .env -f infra/docker-compose.yml up -d --build`.
+2. Apply migrations with `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py migrate`.
+3. Load sample data with `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py seed_scouting_data`.
+4. Create a local user with `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py createsuperuser` if you need a development login.
+5. Visit `http://127.0.0.1:8000/players/` to explore the scouting search MVP.
+6. Use player-level filters (including wingspan), context filters, and stat filters to run scouting searches with sorting and pagination.
+7. Log in at `http://127.0.0.1:8000/accounts/login/` to manage your own shortlist, notes, and saved searches.
+8. Save useful filter combinations from the player search page, rerun them later, or delete them.
+9. Open player detail pages to review context rows and create user-scoped notes.
+10. Use `http://127.0.0.1:8000/favorites/` to review your user-scoped shortlist.
+
+First real-data importer (ADR-0009 baseline):
+- default sample snapshot import:
+  `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py import_hoopdata_demo_competition`
+- explicit input path import:
+  `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py import_hoopdata_demo_competition --input /app/scouting/sample_data/imports/hoopdata_demo_serie_a2_2025_2026.json`
+
+First public European importer (LBA Serie A scope):
+- live public-source import (season start year 2025):
+  `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py import_lba_public_serie_a --season 2025`
+- deterministic local-fixture import:
+  `docker compose --env-file .env -f infra/docker-compose.yml exec -T app python manage.py import_lba_public_serie_a --season 2025 --fixture /app/scouting/sample_data/imports/lba_public_serie_a_fixture.json`
+- note: when the public source does not expose a player position, HoopScout keeps `position` empty instead of fabricating a value.
+
+Legacy shared favorites and notes from the pre-auth MVP are cleared by the early-stage ownership migration so the app can move cleanly to user-scoped data.
 
 ## Workflow
 
-Protected branches:
+- `main` is the stable branch.
-- `main`
+- `develop` is the integration branch.
-- `develop`
+- normal work goes through `feature/*` branches created from `develop`.
+- run `make doctor` before or during local setup to confirm the repository foundation is present.
 
-Normal work goes through `feature/*` branches created from `develop`. Tasks should be completed on the task branch, committed there, and merged back into `develop` when done.
+Durable project behavior belongs in the repository, especially:
+- `AGENTS.md`
+- `.codex/`
+- `.agents/skills/`
+- `docs/`
 
-## Working with Codex
+Local-only responsibilities still include authentication, personal editor setup, shell aliases, and secrets.
-
-Durable project behavior should live in the repository so that work remains consistent across machines and contributors.
-
-Repository-owned configuration examples:
-- task workflow
-- branch strategy
-- coding process
-- agent roles
-- reusable skills
-- machine setup instructions
-- test and validation instructions
-
-Local-only configuration examples:
-- Codex authentication
-- personal shell aliases
-- editor preferences
-- secrets and API keys
-- machine-specific customizations not documented as shared examples
-
-## New Machine Setup
-
-When starting on a new machine:
-1. Clone the repository.
-2. Authenticate Codex locally.
-3. Checkout the correct branch, typically `develop` or the assigned task branch.
-4. Read `AGENTS.md`, `docs/WORKFLOW.md`, `docs/MACHINE_SETUP.md`, `docs/TASK_TEMPLATE.md`, and the current architecture/ADR documents.
-5. Run `make doctor` to validate the local repository bootstrap before starting a task.
-
-## Codex Task Style
-
-Codex tasks in this repository should follow this order:
-1. Confirm branch strategy.
-2. State the branch being used.
-3. List the files to change.
-4. Explain the design briefly.
-5. Make the requested changes.
-6. Update tests and docs when relevant.
-7. Provide the commit message used.
-8. Confirm the merge target.
-9. Stop.
-
-## Local Checks
-
-Run `make doctor` as part of machine/bootstrap validation to confirm the repository foundation is present and aligned.
-
-## Current Status
-
-The repository currently provides:
-- repository bootstrap and workflow foundation
-- Codex/agent collaboration setup
-- portable development baseline
-- accepted phase-1 technical decisions for future implementation work
-
-## Decision Baseline
-
-Future implementation work should follow the accepted ADR baseline unless a later ADR supersedes it.
 
 ## Contributing
 
-To contribute in the current phase:
 - read `AGENTS.md`
 - read `docs/WORKFLOW.md`
 - read the current ADR set in `docs/adr/`
 - create a task branch from `develop`
-- keep tasks narrowly scoped
+- keep tasks narrowly scoped and aligned with accepted decisions

+# ADR-0005: Scouting Search Domain Baseline
+
+## Status
+Accepted
+
+## Context
+HoopScout v2 is moving from technical foundation decisions to product-domain decisions required before model, filter, and UI implementation. The next implementation prompts need a stable and explicit scouting search vocabulary so we do not conflate objective statistics with internal scouting interpretation.
+
+The product intent is a scouting-first player search engine where users combine multiple dimensions to discover players. This is not a generic basketball encyclopedia.
+
+## Decision
+
+### 1. Search purpose
+The search system is defined as a player scouting search engine. Search dimensions are selected to support scouting workflows and shortlist creation, not comprehensive historical/statistical browsing.
+
+### 2. Domain vocabulary and separation of concerns
+Search dimensions are separated into distinct layers that must not be conflated:
+
+- Position: standard on-court category (`PG`, `SG`, `SF`, `PF`, `C`).
+- Role: tactical/scouting classification (for example `playmaker`, `3-and-D`, `point forward`, `rim protector`, `6th man`).
+- Specialty: scouting tag layer (for example `ball handling`, `off ball`, `defense`, `intangibles`, `clutch`, `post`, `dunk`).
+
+Position is a categorical descriptor, role is tactical interpretation, and specialty is a flexible tagging layer. Future implementation must preserve this separation in model semantics, filtering semantics, and UI wording.
+
+### 3. Data classification by search dimension
+The following classification defines ownership and data realism.
+
+| Dimension | Classification | MVP handling |
+|---|---|---|
+| Position (`PG`/`SG`/`SF`/`PF`/`C`) | Hybrid: often source-derived, may need normalization; can be manually overridden when source is inconsistent | In MVP; filterable |
+| Role (listed tactical roles) | App-defined/internal taxonomy; assigned via internal scouting judgment; may be inferred from data but not treated as source-native fact | Deferred as mandatory filter; optional/manual enrichment in MVP |
+| Specialty tags | App-defined/internal taxonomy; manually curated and optionally inference-assisted; not source-native | Deferred as mandatory filter; optional/manual enrichment in MVP |
+| Age | Derived from source date-of-birth and reference date | In MVP; filterable |
+| Height | Source-derived objective attribute; normalized units required | In MVP; filterable |
+| Weight | Source-derived objective attribute; normalized units required | In MVP; filterable |
+| Wingspan | Optional source-derived or manually curated enrichment; sparse in public sources | Not required in MVP; optional if present |
+| Points per game | Source-derived objective per-game metric | In MVP; filterable |
+| Assists per game | Source-derived objective per-game metric | In MVP; filterable |
+| Steals per game | Source-derived objective per-game metric | In MVP; filterable |
+| Turnovers per game | Source-derived objective per-game metric | In MVP; filterable |
+| Blocks per game | Source-derived objective per-game metric | In MVP; filterable |
+| eFG% | Source-derived if provided, otherwise calculated from source box score totals (derived but objective) | In MVP if available/computable |
+| TS% | Source-derived if provided, otherwise calculated from source totals (derived but objective) | In MVP if available/computable |
+| Plus/minus | Optional source-derived metric with context variance across competitions/sources | Deferred from MVP baseline; include only where source quality is acceptable |
+| Offensive rating | Optional source-derived metric; not universally available/consistent | Deferred from MVP baseline |
+| Defensive rating | Optional source-derived metric; not universally available/consistent | Deferred from MVP baseline |
+
+### 4. MVP search scope decision
+MVP search filters include:
+
+- position
+- per-game metrics: points, assists, steals, turnovers, blocks
+- objective personal/physical attributes with practical availability: age, height, weight
+- advanced percentages when available or reliably computable: eFG%, TS%
+
+MVP does not require role, specialty, wingspan, plus/minus, offensive rating, or defensive rating as baseline filters.
+
+These deferred dimensions are allowed as optional enrichment fields in MVP data ingestion/storage if available, but they are not required for a player to be searchable.
+
+### 5. Data realism decisions for risk-prone dimensions
+- Role: public source coverage is inconsistent and mostly interpretive; treat as internal/manual scouting classification in MVP.
+- Specialty: public source coverage is not standardized; treat as internal/manual tagging in MVP.
+- Wingspan: public coverage is sparse and uneven across leagues; treat as optional enrichment, not a required MVP field.
+
+### 6. Flexibility for future taxonomy growth
+Role and specialty taxonomies are repository-owned domain vocabularies. They must be extensible so new role labels and specialty tags can be added without changing the conceptual model.
+
+Future implementation should assume:
+- position remains a bounded standard set;
+- role remains an app-defined tactical taxonomy that can expand;
+- specialty remains an app-defined tag taxonomy that can expand.
+
+### 7. Implementation guidance for future prompts
+Future model/filter/UI prompts must assume:
+
+- Search filters are split by semantic layer: position, role, specialty, objective metrics, physical characteristics.
+- Position filters operate on normalized categorical values.
+- Role and specialty are internal taxonomy-owned dimensions and may be absent for many players in early phases.
+- Objective metrics and physical fields remain source-driven (or objectively derived from source stats) and should be treated differently from scouting classifications.
+- Optional dimensions must not block ingestion or search eligibility when missing.
+- UI wording should avoid presenting role/specialty as objective source facts.
+
+## Alternatives considered
+
+### A. Treat role and specialty as source-native fields in MVP
+Rejected. This overstates source objectivity and creates data quality risk because these are primarily scouting interpretations.
+
+### B. Require all listed dimensions in MVP filters
+Rejected. This increases delivery risk and couples MVP to low-availability fields (especially wingspan and certain advanced metrics).
+
+### C. Ignore role/specialty until much later
+Rejected. Even if deferred as mandatory filters, role/specialty must be conceptually defined now to avoid model ambiguity and rework.
+
+## Trade-offs
+- Pros: clear semantic boundaries, realistic MVP scope, lower ingestion risk, explicit taxonomy ownership.
+- Cons: initial MVP filter set is narrower than full scouting ambition, and some high-value scouting dimensions are manual/optional at first.
+
+## Consequences
+- Near-term implementation can proceed with objective, reliably available filters first.
+- Role/specialty workflows will require internal curation processes and possibly reviewer/admin UX later.
+- Data pipelines must support missing optional fields without breaking search.
+- Future ADRs can refine role/specialty governance and metric computation standards without replacing this baseline separation.
+
+## Follow-up decisions needed
+1. Role taxonomy governance: who can define, merge, rename, or deprecate roles.
+2. Specialty taxonomy governance: naming rules, hierarchy policy (if any), and duplicate-tag handling.
+3. Normalization standards for height/weight units and age reference-date semantics.
+4. Metric computation and rounding policy for derived advanced stats (eFG%, TS%).
+5. Source quality policy for optional advanced metrics (plus/minus, offensive/defensive rating).
+6. Curation workflow for manual scouting classifications and auditability requirements.

+# ADR-0006: Initial Domain Model Baseline
+
+## Status
+Accepted
+
+## Context
+ADR-0005 defined the scouting search domain semantics and MVP filter realism. Before implementing Django models, HoopScout v2 needs an explicit conceptual domain model baseline that translates those search decisions into stable entities, relationships, and ownership boundaries.
+
+The goal of this ADR is to define an MVP domain model that is predictable, implementation-ready, and extensible without premature schema complexity.
+
+## Decision
+
+### 1. Core MVP entities
+The initial MVP conceptual model includes these entities:
+
+- Player
+- Competition
+- Team
+- Season
+- PlayerSeason
+- PlayerSeasonStats
+
+Entity intent:
+- Player: canonical person/athlete identity and durable personal/physical profile.
+- Competition: league/tournament context in which team and season participation occurs.
+- Team: club/franchise identity with competition association in a given season context.
+- Season: time-bounded campaign context (for example 2025-2026).
+- PlayerSeason: player participation context for one season, optionally linked to a primary team and competition.
+- PlayerSeasonStats: objective statistical snapshot attached to one `PlayerSeason`.
+
+MVP split decision:
+- Keep `PlayerSeason` and `PlayerSeasonStats` separate.
+- `PlayerSeason` owns participation/classification context.
+- `PlayerSeasonStats` owns metric values used for search filters.
+
+### 2. Entity relationships (conceptual)
+- One `Player` can have many `PlayerSeason` records.
+- One `Season` can have many `PlayerSeason` records.
+- One `Team` can have many `PlayerSeason` records.
+- One `Competition` can have many `Team` and many `PlayerSeason` records.
+- One `PlayerSeason` has zero or one `PlayerSeasonStats` record in MVP.
+
+Stats ownership decision:
+- Search statistics conceptually belong to the player-in-season unit (`PlayerSeason`) and are stored in `PlayerSeasonStats`.
+- Team and competition are contextual links to that player-season record.
+
+### 3. Position, role, specialty modeling approach
+- Position:
+  - Conceptual type: bounded choice set (enum/choice behavior).
+  - Cardinality in MVP: single-valued on `PlayerSeason`.
+  - Ownership: normalized source-aligned value with optional internal correction.
+
+- Role:
+  - Conceptual type: dedicated taxonomy entity (not a hardcoded enum).
+  - Cardinality in MVP: many-to-many classification from `PlayerSeason` to role taxonomy.
+  - Ownership: internal scouting taxonomy, manually curated and extensible.
+
+- Specialty:
+  - Conceptual type: tag-like taxonomy entity.
+  - Cardinality in MVP: many-to-many classification from `PlayerSeason` to specialty taxonomy.
+  - Ownership: internal scouting tag vocabulary, multi-valued and extensible.
+
+Rationale:
+- Position is stable and bounded; role and specialty are interpretive and expected to evolve.
+
+### 4. Imported vs internal vs inferred boundary
+- Imported source data (objective):
+  - Height, weight, date of birth (source attributes)
+  - Per-game stats: points, assists, steals, turnovers, blocks
+  - Advanced metrics when provided by source: eFG%, TS%, plus/minus, offensive rating, defensive rating
+  - Position when supplied by source (subject to normalization)
+
+- Inferred/derived data:
+  - Age (derived from date of birth and reference date)
+  - eFG% and TS% when computed from source totals
+  - Optional role suggestions generated from rules/models (if introduced later)
+
+- Internal/manual scouting enrichment:
+  - Role assignments
+  - Specialty tags
+  - Position overrides when source labels are inconsistent
+  - Wingspan when collected manually due to sparse public coverage
+
+Hybrid note:
+- Position remains hybrid (source-derived baseline plus internal override path).
+
+### 5. Optional-data handling
+Domain-level required vs optional in MVP:
+
+- Required for MVP search baseline:
+  - Position (normalized single value)
+  - Age (derived, if DOB available)
+  - Height, weight (if available from source; model permits null when missing)
+  - Core per-game stats (points, assists, steals, turnovers, blocks)
+
+- Optional in MVP domain:
+  - Wingspan
+  - Role classifications
+  - Specialty classifications
+  - Plus/minus, offensive rating, defensive rating
+  - Any personal/physical field missing from public source coverage
+
+Optionality rule:
+- Missing optional fields must not block player ingestion or baseline search eligibility.
+
+### 6. MVP scope discipline (intentionally excluded now)
+The initial domain model intentionally excludes:
+
+- manual scouting notes/journal objects
+- watchlists and shortlist collaboration objects
+- player-to-player comparison artifacts
+- transfer-history and contract-history modeling
+- multi-source provenance graph complexity beyond basic source attribution needs
+- versioned taxonomy governance workflows
+
+### 7. Implementation guidance for future prompts
+Future Django model implementation prompts should assume:
+
+- First model wave: `Player`, `Competition`, `Team`, `Season`, `PlayerSeason`, `PlayerSeasonStats`, plus taxonomy models for role and specialty.
+- Keep MVP simple: one primary stats record per player-season context.
+- Position remains a bounded choice; role and specialty must be extensible taxonomies.
+- Role and specialty fields are optional and many-to-many from player-season context.
+- Objective/imported metrics and internal scouting classifications remain semantically separate in naming and model structure.
+- Domain-level optional fields must be nullable/omissible without breaking ingestion flows.
+
+## Alternatives considered
+
+### A. Single flat Player model with season/stat columns
+Rejected. It mixes durable identity with seasonal context and creates update ambiguity.
+
+### B. Attach stats directly to PlayerSeason without a separate stats entity
+Rejected for MVP baseline. Keeping a dedicated `PlayerSeasonStats` concept preserves a clean boundary between participation context and metric payload.
+
+### C. Model role and specialty as fixed enums
+Rejected. These are internal scouting taxonomies expected to evolve and require extensibility.
+
+### D. Require wingspan, role, and specialty at ingest time
+Rejected due to high data-availability risk and poor MVP practicality.
+
+## Trade-offs
+- Pros: clear context boundaries, predictable first implementation pass, extensible scouting taxonomies, realistic handling of missing public data.
+- Cons: introduces more entities than a flat schema and defers richer provenance/taxonomy governance details to later ADRs.
+
+## Consequences
+- Future model implementation can proceed without re-deciding core entity boundaries.
+- Search/filter implementation can rely on player-season as the primary statistical context.
+- Internal scouting enrichment can evolve independently from imported objective stats.
+- Additional complexity (notes, watchlists, provenance depth) remains available for later incremental decisions.
+
+## Follow-up decisions needed
+1. Exact uniqueness constraints for `PlayerSeason` identity (player + season + team + competition semantics).
+2. Minimal provenance metadata required on imported records in MVP.
+3. Normalization standards for team/competition naming and cross-source identity mapping.
+4. Taxonomy governance policy for role/specialty lifecycle changes.
+5. Rules for handling mid-season team changes in MVP vs post-MVP.
+6. Whether advanced metrics should be persisted, computed on read, or both.

+# ADR-0009: Real-Data Ingestion Baseline
+
+## Status
+Accepted
+
+## Context
+The scouting MVP is working with seeded data, but there is no accepted baseline for how real external data should enter the system. Before building the first importer, we need one predictable ingestion shape, clear identity rules, and explicit ownership boundaries so repeated imports are safe and do not damage scouting or user-owned data.
+
+## Decision
+
+### 1. Ingestion strategy baseline
+Use a command-oriented, source-specific baseline.
+
+- Each source gets its own Django management command under `scouting`.
+- The first importer is single-source and single-competition scoped.
+- Command behavior for MVP:
+  - read a structured input payload for one source (no scraping in this phase)
+  - normalize to HoopScout field conventions
+  - validate required identifiers and required MVP fields
+  - upsert supported imported models in deterministic order inside a transaction
+- Keep execution synchronous and local-command driven for now.
+
+This is the smallest safe baseline: simple to run, testable, and repeatable without introducing an ingestion platform.
+
+### 2. Source identity and external identifiers
+Imports must use deterministic matching keys. Fuzzy matching is out of scope for MVP imports.
+
+External identifier policy:
+- `Player`: require source external player ID.
+- `Competition`: require source external competition ID.
+- `Team`: require source external team ID.
+- `Season`: use internal canonical season identity (`name`, `start_year`, `end_year`) as the MVP match key; source season ID may be added later if needed.
+- `PlayerSeason`: require a deterministic context identity built from source IDs for player + season + team + competition.
+- `PlayerSeasonStats`: match strictly by the resolved `PlayerSeason` (one stats row per player-season context in current model).
+
+Model-shape guidance for implementation:
+- Add source-aware external identity mapping support before first importer write path.
+- Preferred MVP shape: small generic mapping table keyed by (`source_name`, `entity_type`, `external_id`) -> internal object reference.
+- Avoid source-specific columns spread across core domain tables in MVP.
+
+Duplication/merge safety rules:
+- Never merge two internal entities without deterministic ID evidence.
+- If deterministic identity is missing, skip row and report validation error (do not guess).
+- Re-running the same source payload must update existing mapped records, not create duplicates.
+
+### 3. Data ownership boundary
+Three ownership zones are explicit:
+
+- Imported source data (updatable by importer):
+  - objective player profile fields provided by source
+  - competition/team/season context fields provided by source
+  - player-season and stats payload fields provided by source
+- Internal scouting enrichment (not overwritten by importer by default):
+  - roles
+  - specialties
+  - future internal scouting metadata unless explicitly marked importer-owned in a later ADR
+- User-scoped product data (never touched by importer):
+  - favorites
+  - notes
+  - saved searches
+
+Importer code must not overwrite user-owned or internal enrichment data unless a later decision explicitly allows it.
+
+### 4. Update semantics baseline
+Repeated imports are expected and must be idempotent.
+
+- Upsert allowed:
+  - `Player`, `Competition`, `Team`, `Season`, `PlayerSeason`, `PlayerSeasonStats` for importer-owned fields only.
+- Immutable/append-only assumptions for MVP:
+  - user-owned tables remain untouched
+  - internal enrichment remains untouched
+  - import-run audit rows (if added) are append-only
+- Optional fields:
+  - missing optional source fields must not block ingestion; store null/empty where allowed
+- Conflict behavior:
+  - deterministic key mismatch or missing required IDs is a row-level error, not a heuristic merge.
+
+### 5. MVP ingestion scope
+The first ingestion implementation must stay narrow:
+
+- one source
+- one competition
+- one command-oriented flow
+- minimal useful fields only (core player identity/profile + player-season context + stats already represented by current model)
+
+No scraping framework, no async worker orchestration, and no multi-source reconciliation engine in this phase.
+
+### 6. Model impact guidance
+Before first importer implementation, introduce only the minimum schema support needed for deterministic identity and repeatability:
+
+- required: source/external ID mapping support
+- recommended: lightweight import-run tracking for observability and replay confidence
+- not required now:
+  - broad domain redesign
+  - full provenance graph
+  - multi-source conflict resolution model
+
+### 7. Implementation guidance for the next prompt
+The next ingestion implementation task should assume:
+
+- first importer shape:
+  - source-specific management command
+  - structured input -> normalize -> validate -> transactional upsert
+- identity matching:
+  - external ID mapping required for player/team/competition/player-season contexts
+  - season matched by canonical internal season identity in MVP
+- repeatability/idempotency:
+  - safe to run same payload multiple times with stable results
+- data touch boundaries:
+  - importer updates only importer-owned objective fields
+  - importer does not modify roles/specialties/favorites/notes/saved searches
+
+## Alternatives considered
+
+### A. Direct ad-hoc scripts that write straight to tables
+Rejected. Too hard to verify, repeat, and maintain safely across contributors.
+
+### B. Full ingestion platform first (queues, orchestrator, multi-source reconciliation)
+Rejected. Too much complexity for current phase and first real importer scope.
+
+### C. Natural-key-only matching without external identifiers
+Rejected. High duplication and ambiguous merge risk across repeated imports.
+
+### D. Source-specific external ID columns on each core model
+Not chosen for MVP baseline. It couples core schema to individual sources and scales poorly when adding sources.
+
+## Trade-offs
+- Pros:
+  - deterministic identity and safer repeat imports
+  - clear ownership boundaries that protect scouting/user data
+  - minimal implementation surface for first real importer
+- Cons:
+  - requires adding mapping support before importer write path
+  - strict ID requirements may reject incomplete rows instead of ingesting partial guesses
+
+## Consequences
+- Future importer implementation can proceed without re-deciding baseline ingestion shape.
+- First importer work will prioritize deterministic mapping and idempotent upserts over source breadth.
+- Search/product layers remain stable while objective source data becomes replaceable and repeatable.
+
+## Follow-up decisions needed
+1. Exact schema design for source/external ID mapping table and object reference strategy.
+2. Whether import-run tracking is mandatory in MVP or phase-2.1.
+3. Field-by-field importer ownership matrix (which columns are importer-owned vs internal-only).
+4. Error-report output format for skipped/invalid rows.
+5. When to add source season external IDs if natural season identity becomes insufficient.
