 - `normalized_item_id` is always present, but it only collapses repeated rows when the evidence is strong; otherwise it falls back to row-level identity via `normalized_row_id`.
 - Added `normalize_*` entry points for the new data-model layout while leaving the legacy `enrich_*` commands available during the transition.
 
+* [ ] t1.14.2: finalize filesystem and schema alignment for the refactor (2-4 commits)
+bring on-disk outputs fully into the target `data/` structure without changing retailer behavior
+
+** Acceptance Criteria
+1. retailer data directories conform to pm/data-model.org:
+   - `data/giant-web/raw/...`
+   - `data/giant-web/collected_orders.csv`
+   - `data/giant-web/collected_items.csv`
+   - `data/giant-web/normalized_items.csv`
+   - `data/costco-web/raw/...`
+   - `data/costco-web/collected_orders.csv`
+   - `data/costco-web/collected_items.csv`
+   - `data/costco-web/normalized_items.csv`
+2. review/combine outputs are moved or rewritten into the target review paths:
+   - `data/review/review_queue.csv`
+   - `data/review/product_links.csv`
+   - `data/review/review_resolutions.csv`
+   - `data/review/purchases.csv`
+   - `data/review/pipeline_status.csv`
+   - `data/review/pipeline_status.json`
+3. old transitional output paths are either:
+   - removed from active script defaults, or
+   - left as explicit compatibility shims with clear deprecation notes
+4. no recollection is required if existing raw files and collected csvs can be moved/copied losslessly into the new structure
+5. no schema information is lost during the move:
+   - raw paths still resolve
+   - collected/normalized csvs still open with the expected headers
+6. README and task/docs reflect the final active paths
+- pm note: prefer moving/adapting existing files over recollecting from retailers unless a real data loss or schema mismatch forces recollection
+- pm note: this is a structure-alignment task, not a retailer parsing task

+* [ ] t1.14.3: retailer-specific Costco normalization cleanup (2-4 commits)
+tighten Costco-specific normalization so normalized item names are cleaner and deterministic retailer grouping is less noisy
+
+** Acceptance Criteria
+1. improve Costco item-name cleanup for obvious non-identity noise, such as:
+   - trailing slash fragments
+   - code tokens and receipt-format artifacts
+   - duplicated measurement fragments already captured in structured fields
+2. preserve deterministic normalization rules only:
+   - exact retailer_item_id
+   - exact cleaned name + same size/pack when needed
+   - approved retailer alias
+   - no fuzzy or semantic matching
+3. normalized Costco names improve on known bad examples, e.g.:
+   - `MANDARIN /` -> cleaner normalized item name
+   - `LIFE 6'TABLE ... /` -> cleaner normalized item name
+4. cleanup does not overwrite retailer truth:
+   - raw `item_name` is unchanged
+   - parsed `size_value`, `size_unit`, `pack_qty`, and pricing fields remain intact
+5. discount-row behavior remains correct:
+   - matched discount rows still populate `matched_discount_amount`
+   - `net_line_total` remains correct
+   - discount rows remain auditable
+6. add regression tests for the cleaned Costco examples and any new parsing rules
+- pm note: keep this explicitly Costco-specific; do not introduce a generic cleanup framework
+- pm note: prefer a short allowlist/blocklist of known receipt artifacts over broad heuristics
