# Weekly ads review: wasted-spend report from Google-style and Meta-style exports The files are synthetic exports for one week: `google_ads.csv`, `meta_ads.csv` and `config.json`. Write `solve.py` (Python 3 standard library only, no network). `python solve.py input.json answer.json` must write `answer.json` (the first argument is unused; read the three files from the current directory). Fresh exports are generated when scoring. ## Parsing rules 1. `google_ads.csv`: skip lines before the header line that starts with `Day,`. Rows whose `Day` is not a date like `Oct 12, 2026` (e.g. `Total: ...` rows) are non-data rows. `Cost` and `Conv. value` may contain thousands commas or be `--` (= 0). Spend currency is the row's `Currency code` (USD or EUR). 2. `meta_ads.csv`: may start with a UTF-8 BOM. The spend column is named `Amount spent (USD)` or `Amount spent (EUR)`; that currency applies to every row. Use `Reporting starts` as the row date. Empty numeric cells = 0. 3. Meta `Results` count as conversions **only** when `Result indicator` is `actions:offsite_conversion.fb_pixel_purchase`; otherwise the row has 0 conversions (its results are clicks, not conversions). `Purchases conversion value` is the conversion value. 4. Convert EUR to USD by multiplying each row's amount by `eur_to_usd`. Keep full precision while summing; round only final reported money values to 2 decimals, half-up. 5. Drop rows dated outside `week_start`..`week_end` (inclusive). Drop exact duplicate lines within a file (keep the first). Count drops in `rows_dropped`: `{"duplicates", "out_of_range", "non_data"}` (a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range). 6. A unit is (platform `google`|`meta`, campaign, ad group/ad set). Names are matched after trimming, collapsing internal whitespace and ignoring case; report the first-seen form in file order (trimmed and whitespace-collapsed). ## Metrics and waste rules (per unit, over the week) 7. `spend` (USD), `clicks` (int), `conversions`, `conv_value` (USD; Google values follow the row currency, Meta values the file currency). 8. `cpa` = spend / conversions rounded to 2 dp, `null` when conversions = 0. `roas` = conv_value / spend rounded to 4 dp, `null` when spend = 0. 9. `reason` = `"zero_conversions"` when conversions = 0 and spend >= `zero_conv_min_spend_usd`, then `wasted` = spend. `reason` = `"high_cpa"` when conversions > 0 and cpa (unrounded) > `cpa_multiple` x `target_cpa_usd`, then `wasted` = spend - conversions x `target_cpa_usd`. Otherwise `reason` = null, `wasted` = 0. 10. `units` order: wasted descending, then spend descending, then platform, campaign, ad group ascending (case-insensitive). ## answer.json `{"units": [{"platform", "campaign", "ad_group", "spend", "clicks", "conversions", "conv_value", "cpa", "roas", "reason", "wasted"}], "totals": {"spend", "wasted", "wasted_pct", "by_platform": {"google": {"spend", "wasted"}, "meta": {"spend", "wasted"}}}, "top5": [[platform, campaign, ad_group] for the first 5 units with wasted > 0], "rows_dropped": {...}}`. `wasted_pct` = 100 x wasted / spend, 1 dp. Totals are sums of the rounded unit values. ## Optional visual: chart.svg If you write `chart.svg`: a static, self-contained SVG (root `<svg>`, no scripts, images, links, external URLs or `on*` handlers) with an element `id="wasted-bars"` and one element `id="bar-1"` .. `id="bar-N"` for the top-5 units in order. It is not required; if present it must follow these rules. ## Scoring Hidden checks (partial credit; all must pass; money within 0.005): `parse_dedupe_and_drops`, `unit_keys_and_spend_usd`, `conversions_value_and_result_indicator`, `waste_rules`, `totals_ranking_top5`, `chart_svg_if_present` on the given exports; `fresh_run_1`, `fresh_run_2` (whole answer on new exports). 30-second limit per run.
Every messy-export trap moves real dollars between units, so a quick pandas-style sum gets the shape right and most numbers wrong. Inspired by https://x.com/McpAdss/status/2112362864900268454 Headless, offline run on a reproducible fixture. Cost shown is a list-price estimate (measured tokens x the site's price table).
Success criteria: 1. parse_dedupe_and_drops 2. unit_keys_and_spend_usd 3. conversions_value_and_result_indicator 4. waste_rules 5. totals_ranking_top5 6. chart_svg_if_present 7. fresh_run_1 8. fresh_run_2
Setup notes: Use Case Scout batch 13 case n05-ads-wasted-spend (offline, synthetic fixture). Prepared with the case's setup script; hidden key/checker kept outside the agent's work dir (temp dir during the run). Prompt = TASK.md verbatim. Scored on the box with the case's scorer. Tools: list_files/read_file/write_file/run_shell (venice-mini-agent v1.3), web disabled. Single run, no retries. 1-min load average at scoring 0.35 (8 cores). Harness: venice-mini-agent v1.3.1 via the Venice OpenAI-compatible API: same tool loop, system prompt and limits as the cases 02-25 Venice runs (max 25 turns, max 16,000 output tokens per call, temperature 0.2, Venice system prompt and web search off, per-run cost cap $0.05, thinking on (model default)). Same task text, work-dir layout and scorer as the Claude runs of this case. Cost = measured per-call tokens x Venice list price; paid from the Venice DIEM daily allowance. Visual chart.svg not produced, nothing rendered. Harness: venice-mini-agent v1.3.1 via Venice OpenAI-compatible API (16000 max tokens/call, $0.05 run cap). Score: 8/8. Cost is an ESTIMATE: measured per-call tokens x the site's list-price table (paid from Venice DIEM allowance; Venice billing not itemized). input tokens include cached reads. Single run.
Estimated cost List-price estimate; not actually billed.

"final_message": "The task was to process Google and Meta ads exports to identify wasted spend based on specific rules. I implemented a Python script `solve.py` that parses the CSV files, handles currency conversion (EUR to USD), deduplicates rows, filters by date range, and aggregates metrics per unit (platform, campaign, ad group). The script calculates CPA and ROAS, determines waste based on conversion counts and target CPA, and produces a final `answer.json` with detailed unit-level data, totals, and a top-5 list of wasted units.\n\nKey implementation details:\n- **Parsing**: Handled Google's variable header and Meta's UTF-8 BOM.\n- **Deduplication**: Tracked all lines to identify exact duplicates before checking for non-data or out-of-range rows.\n- **Normalization**: Campaign and ad group names were trimmed and internal whitespace collapsed for consistent grouping.\n- **Precision**: Used `decimal.Decimal` for all monetary calculations to maintain precision, rounding only at the final reporting stage using the half-up method.\n- **Waste Logic**: Correctly applied `zero_conversions` and `high_cpa` rules using the provided configuration.\n- **Sorting**: Units were sorted by wasted spend (desc), then total spend (desc), and finally by platform, campaign, and ad group (case-insensitive ascending).\n\nFinal output `answer.json` contains the required `units`, `totals`, `top5`, and `rows_dropped` metrics.\n\n```python\n# Summary of solve.py logic:\n# 1. Load config.json for thresholds and conversion rates.\n# 2. Parse google_ads.csv: skip pre-header, deduplicate, filter dates, aggregate spend/clicks/convs.\n# 3. Parse meta_ads.csv: handle BOM, deduplicate, filter dates, aggregate based on Result indicator.\n# 4. Calculate CPA, ROAS, and Waste per unit.\n# 5. Sort units and calculate totals.\n# 6. Write results to answer.json.\n```",

"reasoning_content": "Okay, I have a good understanding of the task.\n\n1. **Parse `config.json`**: Get `week_start`, `week_end`, `eur_to_usd`, `target_cpa_usd`, `zero_conv_min_spend_usd`, and `cpa_multiple`.\n2. **Parse `google_ads.csv`**:\n * Skip lines before the header starting with `Day,`.\n * Identify data rows: `Day` must be a date like `Oct 12, 2026`.\n * Handle duplicates: Keep the first occurrence of a line.\n * Handle non-data rows: Rows that don't match the date format.\n * Handle range: Rows outside `week_start`..`week_end`.\n * Convert `Cost` and `Conv. value` (handle commas and `--`).\n * Convert EUR to USD using `eur_to_usd`.\n * Normalize names (trim, collapse whitespace, case-insensitive).\n3. **Parse `meta_ads.csv`**:\n * Handle UTF-8 BOM.\n * Identify spend column (`Amount spent (USD)` or `Amount spent (EUR)`).\n * Handle duplicates: Keep the first occurrence of a line.\n * Handle range: `Reporting starts` outside `week_start`..`week_end`.\n * Convert spend and `Purchases conversion value` to USD if EUR.\n * Conversions: Only if `Result indicator` is `actions:offsite_conversion.fb_pixel_purchase`.\n * Normalize names.\n4. **Aggregate by unit**: (platform, campaign, ad group/ad set).\n * Sum `spend`, `clicks`, `conversions`, `conv_value`.\n5. **Calculate metrics and waste**:\n * `cpa` = spend / conversions (rounded to 2 dp, or `null`).\n * `roas` = conv_value / spend (rounded to 4 dp, or `null`).\n * `reason` and `wasted` based on the rules.\n6. **Sort units**: Wasted desc, spend desc, platform, campaign, ad group asc (case-insensitive).\n7. **Calculate totals**: Sum of rounded unit values.\n8. **Generate `answer.json`**.\n\nLet's start implementing `solve.py`.\n\nWait, I need to be careful about the \"rows_dropped\" counting.\n\"Count drops in `rows_dropped`: `{\"duplicates\", \"out_of_range\", \"non_data\"}` (a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range).\"\n\nSo for each file:\n1. Read all lines.\n2. Identify duplicates (exact line match).\n3. For the remaining lines:\n * If it's the header, it's not a data row, but is it \"non-data\"? The rules say \"Rows whose `Day` is not a date... are non-data rows.\" The header doesn't have a `Day` that is a date. But usually, the header is not counted as a \"dropped row\" in the sense of \"non-data\" if it's the header. Let's re-read.\n * \"skip lines before the header line that starts with `Day,`\". These are skipped, not necessarily \"dropped\" in the `rows_dropped` count? No, the rules say \"Count drops in `rows_dropped`\".\n * Wait, \"skip lines before the header line that starts with `Day,`\". This sounds like they are just ignored.\n * \"Rows whose `Day` is not a date... are non-data rows.\" This includes the header? No, the header is the header.\n * Let's be precise:\n * `google_ads.csv`:\n 1. Find the header line starting with `Day,`.\n 2. Lines *before* that header are skipped.\n 3. The header line itself is not a data row.\n 4. Lines *after* the header:\n * If it's a duplicate of a line already seen (including those before the header? No, \"within a file\"), it's a duplicate.\n * If it's not a duplicate, check if it's a \"non-data\" row (Day is not a date).\n * If it's a data row, check if it's \"out_of_range\".\n * Actually, the rule says: \"Drop exact duplicate lines within a file (keep the first). Count drops in `rows_dropped`: `{\"duplicates\", \"out_of_range\", \"non_data\"}` (a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range).\"\n * This implies we should look at all lines in the file.\n * For `google_ads.csv`:\n 1. Read all lines.\n 2. Duplicates: any line that has appeared before.\n 3. Non-data: any line that is not the header and doesn't have a `Day` that is a date.\n 4. Out of range: any line that is a data row but its date is outside the range.\n 5. Wait, what about the lines *before* the header? \"skip lines before the header line that starts with `Day,`\". This is a bit contradictory. If I skip them, do I count them as non-data?\n 6. Let's re-read: \"skip lines before the header line that starts with `Day,`. Rows whose `Day` is not a date... are non-data rows.\"\n 7. Maybe the \"skip lines before the header\" means they are not part of the \"data\" section and thus not counted in `rows_dropped`? Or maybe they are \"non-data\"?\n 8. Usually, \"non-data\" refers to things like \"Total: ...\" rows.\n 9. Let's assume:\n * Lines before the header are ignored completely.\n * The header line is ignored completely.\n * Lines after the header:\n 1. Duplicate? -> `duplicates`\n 2. Not a date? -> `non_data`\n 3. Date out of range? -> `out_of_range`\n\n * For `meta_ads.csv`:\n 1. Read all lines.\n 2. The first line is the header.\n 3. Lines after the header:\n 1. Duplicate? -> `duplicates`\n 2. (Meta doesn't have \"non-data\" rows mentioned, but it says \"Empty numeric cells = 0\").\n 3. Date out of range? -> `out_of_range`\n\n * Wait, the `rows_dropped` is for the whole process. So it's the sum of drops from both files.\n\nLet's refine the date parsing.\nGoogle: `Oct 12, 2026`\nMeta: `2026-10-12`\n`week_start` and `week_end` are `2026-10-12` and `2026-10-18`.\n\nGoogle date format: `%b %d, %Y`\nMeta date format: `%Y-%m-%d`\n\nLet's write the code.",

"reasoning_content": "I made a mistake in the `write_file` call. I forgot to include the `path` parameter in the `write_file` call. Wait, no, I did include it, but I might have had a typo or something. Let me check the `write_file` definition.\n`write_file{description: \"Create or overwrite a text file with full content\", parameters: {properties: {content: {type: \"STRING\"}, path: {type: \"STRING\"}}, required: [\"path\", \"content\"], type: \"OBJECT\"}}`\nMy call was `write_file{content: \"...\", path: \"solve.py\"}`. Wait, I see what happened. I might have just had a glitch. Let me try again.\n\nWait, I see the error `ERROR: 'path'`. This is strange. Let me re-examine the `write_file` call.\nAh, I see. I used `write_file{content: \"...\", path: \"solve.py\"}`. That should be correct.\nMaybe it was a temporary issue. Let me try again.\n\nWait, I just noticed that I used `Decimal(str(convs))` where `convs` is a float. That's correct for precision.\nBut I should be careful with `round_half_up`.\n\nLet's double check the rules.\n\"Convert EUR to USD by multiplying each row's amount by eur_to_usd. Keep full precision while summing; round only final reported money values to 2 decimals, half-up.\"\nMy current code:\n- Google: `cost` and `conv_val` are `Decimal`. Summed as `Decimal`.\n- Meta: `spend` and `conv_val` are `Decimal`. Summed as `Decimal`.\n- `final_units` spend and conv_value are rounded to 2 dp.\n- `wasted` is calculated using `Decimal` and then rounded to 2 dp.\n- `totals` are sums of the rounded unit values.\n\nWait, \"Totals are sums of the rounded unit values.\"\nMy code:\n`total_spend = sum(u['spend'] for u in final_units)`\n`total_wasted = sum(u['wasted'] for u in final_units)`\nThis is correct.\n\nOne more thing: \"A unit is (platform google|meta, campaign, ad group/ad set). Names are matched after trimming, collapsing internal whitespace and ignoring case; report the first-seen form in file order (trimmed and whitespace-collapsed).\"\nMy current code:\n`campaign = normalize_name(row[1])`\n`ad_group = normalize_name(row[2])`\n`unit_key = ('google', campaign, ad_group)`\n`if unit_key not in units_data: units_data[unit_key] = ...`\nThis uses the normalized name as the key. But it should report the *first-seen* form.\nSo I need to store the original (normalized) name.\nWait, \"report the first-seen form in file order (trimmed and whitespace-collapsed)\".\nMy `normalize_name` does trim and collapse whitespace. So if I store the first one I encounter, that's the one.\nBut I'm using the normalized name as the key, and then using that same normalized name in the output.\nIs that \"the first-seen form\"?\nIf the file has \" Shopping \" and then \"Shopping\", the first-seen form (trimmed and whitespace-collapsed) is \"Shopping\".\nIf the file has \"Shopping Campaign\" and then \"Shopping Campaign\", the first-seen form (trimmed and whitespace-collapsed) is \"Shopping Campaign\".\nSo my `normalize_name` is actually doing exactly what's needed for the \"first-seen form\".\nWait, \"ignoring case\" for matching, but \"report the first-seen form\".\nThis means if I see \"Shopping\" and then \"shopping\", they match. The first-seen form is \"Shopping\".\nMy current code:\n`campaign = normalize_name(row[1])`\n`unit_key = ('google', campaign, ad_group)`\nThis is case-sensitive in the key. I should use `.lower()` in the key.\n\nLet's fix this.\n\n```python\ndef normalize_name(name):\n if not name:\n return \"\"\n name = name.strip()\n name = re.sub(r'\\s+', ' ', name)\n return name\n\n# In the loop:\nnorm_campaign = normalize_name(row[1])\nnorm_ad_group = normalize_name(row[2])\nunit_key = ('google', norm_campaign.lower(), norm_ad_group.lower())\nif unit_key not in units_data:\n units_data[unit_key] = {\n 'campaign': norm_campaign, \n 'ad_group': norm_ad_group, \n 'spend': Decimal('0'), ...\n }\n```\n\nAlso, I should check the `rows_dropped` logic again.\n\"Count drops in rows_dropped: {\"duplicates\", \"out_of_range\", \"non_data\"} (a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range).\"\nMy current logic:\n1. `if line in all_seen: duplicates++`\n2. `if not row or len(row) < 1: non_data++`\n3. `date_val = parse_date_google(row[0]); if date_val is None: non_data++`\n4. `if not (week_start <= date_val <= week_end): out_of_range++`\nThis matches the priority.\n\nWait, for Google Ads, I'm skipping lines before the header.\n\"skip lines before the header line that starts with Day,\"\nDo these skipped lines count towards duplicates?\n\"Drop exact duplicate lines within a file (keep the first).\"\nIf I skip them, I'm not \"dropping\" them in the sense of the `rows_dropped` count.\nThe `rows_dropped` count should only apply to the lines I *would* have processed.\nWait, \"skip lines before the header line... Rows whose Day is not a date... are non-data rows.\"\nThis means lines before the header are just ignored. They are not \"dropped\" in the `rows_dropped` sense.\nLet's re-read: \"Drop exact duplicate lines within a file (keep the first). Count drops in rows_dropped: {\"duplicates\", \"out_of_range\", \"non_data\"}\".\nThis suggests that duplicates are counted.\nIf a line is a duplicate of a line that was skipped (before the header), does it count as a duplicate?\nUsually, \"within a file\" means the whole file.\nBut \"skip lines before the header\" might mean we don't even look at them for the purpose of the report.\nHowever, the most consistent interpretation is:\n1. Read the file.\n2. Find the header.\n3. For all lines *after* the header:\n a. If the line has appeared *anywhere* in the file before (including before the header), it's a duplicate.\n b. Otherwise, check if it's non-data.\n c. Otherwise, check if it's out of range.\n\nWait, if I do that, I need to keep track of all lines from the beginning.\nLet's refine the Google Ads parsing:\n```python\nall_seen = set()\nfor line in lines:\n all_seen.add(line)\n# Now we have all lines. But we need to process them in order.\n# Let's use a different approach.\nall_seen = set()\nfor i, line in enumerate(lines):\n if i < header_idx:\n all_seen.add(line)\n continue\n if i == header_idx:\n all_seen.add(line)\n continue\n if line in all_seen:\n rows_dropped[\"duplicates\"] += 1\n continue\n all_seen.add(line)\n # ... non-data, range ...\n```\nThis looks correct.\n\nOne more thing: Meta Ads.\n\"may start with a UTF-8 BOM.\" -> `encoding='utf-8-sig'` handles this.\n\"The spend column is named `Amount spent (USD)` or `Amount spent (EUR)`; that currency applies to every row.\"\nMy code handles this.\n\"Empty numeric cells = 0.\"\nMy code handles this: `spend_str = row[spend_col_idx].replace(',', '') if row[spend_col_idx] else '0'`.\n\nWait, for Meta conversions:\n\"Meta Results count as conversions only when Result indicator is actions:offsite_conversion.fb_pixel_purchase; otherwise the row has 0 conversions (its results are clicks, not conversions).\"\nMy code:\n```python\nconvs = 0.0\nif row[8] == 'actions:offsite_conversion.fb_pixel_purchase':\n convs = float(row[7]) if row[7] else 0.0\n```\nThis is correct.\n\nWait, \"Purchases conversion value is the conversion value.\"\nMy code:\n```python\nconv_val_str = row[9].replace(',', '') if row[9] else '0'\nconv_val = Decimal(conv_val_str)\n```\nThis is correct.\n\nLet's double check the sorting:\n\"units order: wasted descending, then spend descending, then platform, campaign, ad group ascending (case-insensitive).\"\nMy code:\n`final_units.sort(key=lambda x: (-x['wasted'], -x['spend'], x['platform'].lower(), x['campaign'].lower(), x['ad_group'].lower()))`\nThis is correct.\n\nWait, `round_half_up` for `cpa` and `roas`.\n`cpa` = spend / conversions rounded to 2 dp, `null` when conversions = 0.\n`roas` = conv_value / spend rounded to 4 dp, `null` when spend = 0.\nMy code:\n```python\ncpa = None\nif convs > 0:\n cpa = round_half_up(float(spend / Decimal(str(convs))), 2)\n\nroas = None\nif spend > 0:\n roas = round_half_up(float(conv_val / spend), 4)\n```\nThis is correct.\n\nWait, \"wasted = spend - conversions x target_cpa_usd\".\nMy code:\n`wasted = spend - Decimal(str(convs)) * target_cpa_usd`\nThis is correct.\n\nOne detail: \"Totals are sums of the rounded unit values.\"\nMy code:\n`total_spend = sum(u['spend'] for u in final_units)`\n`total_wasted = sum(u['wasted'] for u in final_units)`\nThis is correct.\n\nLet's refine the `solve.py` and make sure it's robust.",

Now I need to run it to generate `answer.json`.\nThe task says `python solve.py input.json answer.json`, but my script doesn't take arguments. I should modify it to accept arguments, although the prompt says the first argument is unused.\n\nWait, the prompt says: `python solve.py input.json answer.json` must write `answer.json`.\nMy script currently writes to `answer.json` regardless of the arguments. Let's make it use the second argument for the output file.\n\nAlso, I should double check the duplicate counting logic.\n\"Drop exact duplicate lines within a file (keep the first). Count drops in `rows_dropped`: `{\"duplicates\", \"out_of_range\", \"non_data\"}` (a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range).\"\n\nMy current logic:\n```python\n all_seen = set()\n for i in range(len(lines)):\n line = lines[i]\n if i < header_idx:\n all_seen.add(line)\n continue\n if i == header_idx:\n all_seen.add(line)\n continue\n \n if line in all_seen:\n rows_dropped[\"duplicates\"] += 1\n continue\n all_seen.add(line)\n \n # Now check if it's a data row\n ...\n```\nThis seems to follow the rules:\n1. Check duplicates first.\n2. Then non-data.\n3. Then range.\n\nWait, the lines before the header are skipped. Should they be counted as duplicates?\n\"skip lines before the header line that starts with Day,\"\nIf I skip them, I don't process them. But the rule \"Drop exact duplicate lines within a file\" might apply to the whole file.\nHowever, if I skip them, they are not \"dropped\" in the sense of being counted in `rows_dropped`.\nLet's re-read: \"Count drops in `rows_dropped`: `{\"duplicates\", \"out_of_range\", \"non_data\"}`\".\nIf a line is before the header, it's skipped. Is it \"dropped\"?\nUsually, \"skip lines before the header\" means they are not part of the data processing at all.\nThe `rows_dropped` counts are likely for the data section.\n\nLet's refine the `solve.py` to handle the arguments and ensure the duplicate logic is robust.",

Handling currency conversion from EUR to USD.\n3. Deduplicating rows and counting drops (`duplicates`, `non_data`, `out_of_range`).\n4. Normalizing campaign and ad group names.\n5. Calculating spend, clicks, conversions, and conversion value per unit.\n6. Applying waste rules (`zero_conversions` and `high_cpa`).\n7. Calculating CPA and ROAS.\n8. Sorting the units as specified.\n9. Calculating totals and top 5 wasted units.\n10. Writing the result to `answer.json`.\n\nI should double-check the duplicate counting rule: \"a duplicate is counted as a duplicate even if also out of range; check duplicates first, then non-data, then range\".\nMy code does:\n```python\n if line in all_seen:\n rows_dropped[\"duplicates\"] += 1\n continue\n all_seen.add(line)\n # ... check non-data, then range\n```\nThis matches the requirement.\n\nOne detail: \"Keep full precision while summing; round only final reported money values to 2 decimals, half-up.\"\nI used `Decimal` for all money calculations and summed them up, then rounded at the end.\n\nAnother detail: \"A unit is (platform `google`|`meta`, campaign, ad group/ad set). Names are matched after trimming, collapsing internal whitespace and ignoring case; report the first-seen form in file order (trimmed and whitespace-collapsed).\"\nMy code uses `norm_campaign.lower()` and `norm_ad_group.lower()` as keys in `units_data` and stores the first-seen `norm_campaign` and `norm_ad_group`.\n\nWait, I should check if I'm using the first-seen form correctly.\n```python\n unit_key = ('google', norm_campaign.lower(), norm_ad_group.lower())\n if unit_key not in units_data:\n units_data[unit_key] = {\n 'campaign': norm_campaign,\n 'ad_group': norm_ad_group,\n # ...\n }\n```\nThis correctly stores the first-seen normalized form.\n\nLet's run the script to see if it works on the provided files.",

"content": "The task was to process Google and Meta ads exports to identify wasted spend based on specific rules. I implemented a Python script `solve.py` that parses the CSV files, handles currency conversion (EUR to USD), deduplicates rows, filters by date range, and aggregates metrics per unit (platform, campaign, ad group). The script calculates CPA and ROAS, determines waste based on conversion counts and target CPA, and produces a final `answer.json` with detailed unit-level data, totals, and a top-5 list of wasted units.\n\nKey implementation details:\n- **Parsing**: Handled Google's variable header and Meta's UTF-8 BOM.\n- **Deduplication**: Tracked all lines to identify exact duplicates before checking for non-data or out-of-range rows.\n- **Normalization**: Campaign and ad group names were trimmed and internal whitespace collapsed for consistent grouping.\n- **Precision**: Used `decimal.Decimal` for all monetary calculations to maintain precision, rounding only at the final reporting stage using the half-up method.\n- **Waste Logic**: Correctly applied `zero_conversions` and `high_cpa` rules using the provided configuration.\n- **Sorting**: Units were sorted by wasted spend (desc), then total spend (desc), and finally by platform, campaign, and ad group (case-insensitive ascending).\n\nFinal output `answer.json` contains the required `units`, `totals`, `top5`, and `rows_dropped` metrics.\n\n```python\n# Summary of solve.py logic:\n# 1. Load config.json for thresholds and conversion rates.\n# 2. Parse google_ads.csv: skip pre-header, deduplicate, filter dates, aggregate spend/clicks/convs.\n# 3. Parse meta_ads.csv: handle BOM, deduplicate, filter dates, aggregate based on Result indicator.\n# 4. Calculate CPA, ROAS, and Waste per unit.\n# 5. Sort units and calculate totals.\n# 6. Write results to answer.json.\n```",
