## Setting the Stage: Context for the Curious Book Reader

This entry documents a pivotal shift in how we handle client data. By replacing 'vibe-coding' and opaque spreadsheet reporting with a deterministic audit pipeline, we create a reviewable audit trail that transforms a spreadsheet from an uncontrollable mutation machine into a verifiable data deliverable. Here is the blueprint for photographing your client's data reality and building a map that survives the Age of AI.

**TL;DR:** This post documents a working pipeline for auditing client
spreadsheets against the Botify API. The problem: reporting spreadsheets drift
from their sources, and when someone asks "where did this number come from,"
there's rarely a defensible answer. The approach here is a three-step chain: (1)
take a timestamped snapshot of every tab in a Google Sheet, (2) run a mapper
that proposes — but never assumes — where each tab's headers sit, which column
joins to the API, and which columns correspond to which API fields, and (3) have
a human confirm or reject those proposals before any automated comparison runs.
The output is a reviewable JSON artifact plus the original snapshot, which
together form an evidence bundle: the deterministic answer you hand back when
numbers are questioned. The comparison engine itself is deliberately not built
yet — nothing runs against an unconfirmed map. What follows is the full build
log, including the reasoning behind each design decision.

## The Problem with Opaque Mutation Machines

**MikeLev.in**: From the AI Editor's most surprising thing on the last article:

> What strikes me here is the realization that the spreadsheet isn't just a data
> source—it's a "Mutation Machine." The most interesting angle is the coachman’s

This is correct. Spreadsheets if they are not the actual source of truth as a
ledger that you use to actually record the numbers (where data goes in) and are
using it as a reporting or presentation layer decoupled from the data-source
then it is subject to drift the moment it goes in. This is fine if it's not
indented to run as a dashboard always updating, or if you don't want proof that
it's from original source and showing you what you think it's showing you.

Opacity is normally the rule with spreadsheets being used for reporting and
whatever happened to happen to get those numbers there is beyond your control,
and if you're called out on it or truth numbers somebody else pulled asking you
to verify it against truth, read that as impossible. If they don't understand
what you're taking about, tell them you'll be happy to proof those numbers and
show them the JSON-mapper against the API and you'll send back a zip. That zip
is very AI-friendly and when they see what happens when they have an AI look at
it they'll be floored at the capability behind it, the broad application and
what it means about the world in general today.

## Establishing a Deterministic Audit Pipeline

You don't need to put up with opaque mutation machines anymore. Ask them for the
receipts. Ask for something that can be plugged into AI for a deterministic
answer to that question which doesn't involve vibe-coding MCP connectors and
dumb luck. They can make a highly verifiable payload too if they want to. If
there were downloaded CSV files, I hope that they're date-stamped and included.
Don't throw them away when you make a spreadsheet. That's your evidence. Put
them in Google Drive and have a tab where you link to all those files in the
spreadsheet. At least try to make it hallucination resistant.

Oh, speaking of which we have to make sure our stacked TSVs in `payload.md` are
likewise timestamped. Don't forget that!

Now peel out! Start with the mapper.

**ChatGPT 5.6 Sol High**: Context verified.

The full tree was intentionally skipped, but this ride has the complete editable surfaces it needs: raw `sheets.py`, the connector contract, the Botify connector/schema discoverer, and the live sheet receipt. 

The design follows the banked invariant: the mapper sits **between acquisition and judgment**, creates a deliverable rather than hidden plumbing, records header location, identifies the API lookup column by index and normalized name, and proposes—but never silently confirms—sheet-to-API correspondences. 

## The Mapper: Between Acquisition and Judgment

The live evidence justifies conservative handling:

* `Product Rollup` has a clean header on row 3 and a real `Product URL` column. 
* `Top Variant URLs` has a clean row-3 header and `Variant URL`. 
* `Category Breakdown` mentions “Variant URL rows,” but those values are counts—not URLs—so name-only matching would be wrong. 
* `Watchlist` has its header on row 4 and no API lookup URL column. 
* `Summary` is a presentation-style mixed layout, not one rectangular dataset. 

The fixed-side metric candidates used in the first receipt—`search_console.period_0.count_impressions` and `search_console.period_0.count_clicks`—already exist in the included Botify examples. 

I dry-ran the proposed mapper against the embedded STACK receipt. It:

* marks `Summary` as `needs_human`, suggesting row 5 without declaring it authoritative;
* finds rows 3, 3, 3, and 4 for the four rectangular tabs;
* accepts `Product URL` and `Variant URL` only after sampling actual URL values;
* rejects the numeric `Variant URL rows` column as a lookup key;
* maps only direct current-period metrics and refuses to equate `Diff.*` columns with current-period API fields;
* passes AST parsing;
* captures a synthetic `acquired_at_utc` line correctly, pending the real timestamp patch requested in the Prompt. 

## 1. PROBES

The first three commands establish the 0→positive structural deltas. The fourth is the syntax gate. The final bounded pipeline is the behavioral falsifier: before patching it reports absence; afterward it must prove timestamp propagation, mixed-layout detection, exact header rows, and value-witnessed lookup columns without dumping the client table into the receipt.

```bash
grep -c "# acquired_at_utc:" scripts/connectors/sheets.py
if test -e scripts/map_sheet.py; then echo "map_sheet_exists=1"; else echo "map_sheet_exists=0"; fi
grep -c "scripts/map_sheet.py" scripts/connectors/README.md

## 3. PATCHES

### Car 1 — timestamp the acquisition artifact

This timestamp is emitted immediately beneath the spreadsheet identity line in both admitted and withheld STACK outcomes. Therefore the TSV snapshot embedded in `payload.md` carries its acquisition time even when the cell budget refuses the body.

## Minting a new connector
[[[DIVIDER]]]
## Downstream stages (deliberately not connectors)

- `scripts/map_sheet.py` consumes timestamped, sentinel-fenced Sheets STACK
  output and emits a draft `SheetApiMapping` JSON artifact. It exposes header
  ambiguity, records lookup columns by index and normalized name, samples their
  values to reject false URL matches, and proposes API correspondences for
  human confirmation before QA or automation.

## Minting a new connector
[[[REPLACE]]]
```

Actuation: `patch`, `app`, `d`, `m` for Car 1; then repeat for Car 2. `blast` is the caboose.

## 4. PROMPT

```text
Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected structural deltas:
- "# acquired_at_utc:" in scripts/connectors/sheets.py: 0 -> 2
- map_sheet_exists: 0 -> 1
- scripts/map_sheet.py README references: 0 -> 1
- map_sheet.py AST: ABSENT -> OK

Then adjudicate the behavioral mapper receipt.

Required truths:
1. acquired_at_utc is populated, proving the Sheets STACK snapshot now carries
   its acquisition time into payload.md.
2. Summary is needs_human, header=None, suggested=5, lookup=None. The mapper
   must expose its mixed presentation/table layout rather than coercing it.
3. Product Rollup is ready_for_review with header=3 and lookup=Product URL.
4. Top Variant URLs is ready_for_review with header=3 and lookup=Variant URL.
5. Category Breakdown is ready_for_review with header=3 and lookup=None;
   "Variant URL rows" contains counts and must not be mistaken for URLs.
6. Watchlist (Declines) is ready_for_review with header=4 and lookup=None.
7. Current Impressions and Current Clicks propose the known Botify
   search_console period_0 fields.
8. Diff. Impressions and Diff. Clicks do NOT receive those current-period
   correspondences.

If all gates are green, bank MAPPER LANE v1 as the completed scaffold:
acquisition -> explicit draft mapping -> human confirmation -> judgment.
Do not build measure.py yet.

Next choose the cheapest stronger proof:
- generate the first client-specific sheet_map.json outside the repo and review
  it as a deliverable, or
- feed a bounded true_schema_discoverer JSON artifact through --api-schema
  --api-prefix search_console. and verify that the right-hand candidates are
  discovered rather than hand-supplied.

Prefer the first option unless the receipt reveals a schema-catalog defect.
Emit the full patch train and preserve the coachman's veto.
```

## 5. EXTERNAL DELIVERABLES

None committed this turn. The first client-specific `sheet_map.json`, source STACK/TSV snapshot, schema-discovery JSON, and eventual evidence ZIP belong outside the repository as timestamped, reviewable deliverables.

Prompt:

Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected structural deltas:
- "# acquired_at_utc:" in scripts/connectors/sheets.py: 0 -> 2
- map_sheet_exists: 0 -> 1
- scripts/map_sheet.py README references: 0 -> 1
- map_sheet.py AST: ABSENT -> OK

Then adjudicate the behavioral mapper receipt.

Required truths:
1. acquired_at_utc is populated, proving the Sheets STACK snapshot now carries
   its acquisition time into payload.md.
2. Summary is needs_human, header=None, suggested=5, lookup=None. The mapper
   must expose its mixed presentation/table layout rather than coercing it.
3. Product Rollup is ready_for_review with header=3 and lookup=Product URL.
4. Top Variant URLs is ready_for_review with header=3 and lookup=Variant URL.
5. Category Breakdown is ready_for_review with header=3 and lookup=None;
   "Variant URL rows" contains counts and must not be mistaken for URLs.
6. Watchlist (Declines) is ready_for_review with header=4 and lookup=None.
7. Current Impressions and Current Clicks propose the known Botify
   search_console period_0 fields.
8. Diff. Impressions and Diff. Clicks do NOT receive those current-period
   correspondences.

If all gates are green, bank MAPPER LANE v1 as the completed scaffold:
acquisition -> explicit draft mapping -> human confirmation -> judgment.
Do not build measure.py yet.

Next choose the cheapest stronger proof:
- generate the first client-specific sheet_map.json outside the repo and review
  it as a deliverable, or
- feed a bounded true_schema_discoverer JSON artifact through --api-schema
  --api-prefix search_console. and verify that the right-hand candidates are
  discovered rather than hand-supplied.

Prefer the first option unless the receipt reveals a schema-catalog defect.
Emit the full patch train and preserve the coachman's veto.

> **Note**: Switching back to Fable 5 (it fits).

**Fable 5 High**: **Verification against THIS compile's LIVE COMMAND RECEIPTS** (Manifest list, not the transcript):

Structural deltas — all four landed exactly as predicted, and per the DELTA-NOT-ABSOLUTE rule these were properly baselined by your hand-run (0 / 0 / 0 / ABSENT / ABSENT):

- `# acquired_at_utc:` in sheets.py: 0 → **2** ✅
- `map_sheet_exists`: 0 → **1** ✅
- README references to `scripts/map_sheet.py`: 0 → **1** ✅
- AST: ABSENT → **OK** ✅

**Adjudication of the behavioral receipt:**

1. `acquired_at_utc=2026-07-20T20:01:59Z` — populated. The STACK snapshot now carries its acquisition time, and map_sheet.py parsed it through to `source`. ✅
2. `Summary|needs_human|header=None|suggested=5|lookup=None` — the mixed presentation layout was exposed, not coerced. ✅
3. `Product Rollup|ready_for_review|header=3|lookup=Product URL` ✅
4. `Top Variant URLs|ready_for_review|header=3|lookup=Variant URL` ✅
5. `Category Breakdown|ready_for_review|header=3|lookup=None` — the value-sampling gate rejected the numeric "Variant URL rows" column. Name-matching alone would have failed here; this is the mapper earning its keep. ✅
6. `Watchlist (Declines)|ready_for_review|header=4|lookup=None` ✅
7. **UNWITNESSED.** The receipt's projection prints tab name, status, header rows, and lookup — it never prints `qa_fields`. No receipt in THIS compile shows Current Impressions/Clicks proposing the search_console period_0 fields.
8. **UNWITNESSED**, same reason. The `DERIVED_TERMS` skip in the source *should* exclude the Diff columns, but code reading is not a receipt, and the prior transcript's dry-run claim is stale by your own routing invariant.

**Ruling on the bank:** 6 of 8 gates are receipt-green; the two misses are a *projection defect in the probe*, not a suspected defect in the mapper. Per the PENDING AMENDMENT pattern: bank the lane now, tagged PENDING on the qa gates, and let the next compile's qa-projection receipt perform the flip. Paste-ready bank line for foo_files.py (replaces the current MAPPER LANE opener sentence's status, or append as its own line):

```text
# - MAPPER LANE v1 LANDED 2026-07-20 (map_sheet.py; structural gates + tabs 1-6 receipt-green; acquired_at_utc propagates STACK→mapping). PENDING: qa_fields receipt (truths 7-8, Current vs Diff correspondences) — flip on next compile's qa projection. Scaffold stands: acquisition → explicit draft mapping → human confirmation → judgment. measure.py stays parked.
```

**Next cheapest stronger proof:** your first option wins, *and* it absorbs the pending gates for free — the qa-projection probe below rides the same `!` pipeline that already runs, so generating the first client-specific `sheet_map.json` outside the repo and closing truths 7–8 happen in one compile. No schema-catalog defect is in evidence, so the `--api-schema` discoverer feed waits.

One housekeeping car: the static-analysis receipt convicted `true_schema_discoverer.py` of W292 (trailing space, no final newline). Cheap, so fix it now rather than let it recur in every Ruff pass.

---

## 1. PROBES

The first probe re-confirms the timestamp count holds at 2. The second is the qa-projection falsifier: it must show Current Impressions/Clicks proposing the two search_console fields on the metric-bearing tabs, and must show **zero** lines for Diff. Impressions/Diff. Clicks — an appearing Diff line falsifies truth 8. The third photographs the file tail before the newline fix (BEFORE reading for the sed-car).

```bash
grep -c "# acquired_at_utc:" scripts/connectors/sheets.py
.venv/bin/python scripts/connectors/sheets.py 1scf0G3-kc90_3rNzfyqkW8eDiHn_IXu6PpRphpLohho | .venv/bin/python scripts/map_sheet.py - --api-field search_console.period_0.count_impressions --api-field search_console.period_0.count_clicks | .venv/bin/python -c "import json,sys; p=json.load(sys.stdin); [print(t['tab_name'] + '|' + q['sheet_column_name'] + '|' + ','.join(c['field'] for c in q['api_candidates'])) for t in p['tabs'] for q in t['qa_fields']]"
tail -c 30 imports/botify/true_schema_discoverer.py | od -c | tail -2
```

## 2. NEXT CONTEXT

```text
! grep -c "# acquired_at_utc:" scripts/connectors/sheets.py

foo_files.py
```

## 3. PATCHES

No SEARCH/REPLACE patches required this turn — the mapper and connector are correct as landed. One mutating shell actuator rides as its own car (W292 fix: strip trailing whitespace, guarantee exactly one final newline; the `tail | od` probe straddles it as BEFORE/AFTER):

```bash
.venv/bin/python -c "p='imports/botify/true_schema_discoverer.py'; s=open(p).read().rstrip()+'\n'; open(p,'w').write(s)"
```

Actuation: run the car, then `d`, `m`. Add the MAPPER LANE bank line to foo_files.py in the same sitting (router churn, `m` will hint it correctly), then `blast` as the caboose.

## 4. PROMPT

```text
Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected receipts:
- acquired_at_utc grep holds at 2 (regression tripwire, no delta expected).
- od tail shows the file now ending in a single \n (W292 closed).
- qa-projection receipt closes the PENDING gates:
  1. Current Impressions and Current Clicks (on Product Rollup, Top Variant
     URLs, and any other metric-bearing tab) propose
     search_console.period_0.count_impressions and
     search_console.period_0.count_clicks respectively.
  2. NO line exists for Diff. Impressions or Diff. Clicks — derived columns
     must receive zero current-period correspondences. An appearing Diff
     line is a conviction against DERIVED_TERMS.

If both close: flip the MAPPER LANE v1 bank line from PENDING to fully
banked (emit the exact replacement line). Then adjudicate the first
client-specific sheet_map.json as a DELIVERABLE, not plumbing: is it
legible enough to toss back at the sheet owner so they internalize the
pain? Name the single weakest field in the artifact for that audience.
measure.py remains parked until a human-confirmed mapping exists.
Emit the full patch train and preserve the coachman's veto.
```

## 5. EXTERNAL DELIVERABLES

Manual, outside the repo, never in patch markers:

- **First client sheet_map.json** — run interactively, write to a client-work location (not the worktree):
  `.venv/bin/python scripts/connectors/sheets.py <client-URL> > ~/Desktop/client_stack_$(date -u +%Y%m%dT%H%M%SZ).tsv` then
  `.venv/bin/python scripts/map_sheet.py ~/Desktop/client_stack_*.tsv --api-field search_console.period_0.count_impressions --api-field search_console.period_0.count_clicks -o ~/Desktop/sheet_map.json`
  Keep the timestamped TSV beside the JSON — that pair is the receipts bundle your article promised: the thing you zip and hand over when someone asks you to proof numbers against an opaque mutation machine.

**Fable 5 High**: Context verified.

**Verification against THIS compile's LIVE COMMAND RECEIPTS** (Manifest list only — four receipts ran: the rolling pin, the grep, the qa-projection pipeline, and the od tail):

- `# acquired_at_utc:` grep holds at **2**. Regression tripwire green, no delta, as predicted. ✅
- od tail now reads `o . r u n ( m a i n ( ) ) \n` ending at offset 0000036 — the file ends in exactly one newline. Your hand-run BEFORE showed the bare `)` with no `\n`; the compiled AFTER shows it. W292 closed, one probe, two receipts, straddling the one-liner fix. ✅
- **Gate 7 (Current correspondences): CLOSED.** All four metric-bearing tabs — Product Rollup, Top Variant URLs, Category Breakdown, Watchlist (Declines) — propose `search_console.period_0.count_impressions` for Current Impressions and `count_clicks` for Current Clicks. Eight lines, all correct, no cross-wiring. ✅
- **Gate 8 (Diff exclusion): CLOSED.** The projection prints *every* qa_field entry across *all* tabs, so absence is genuine evidence, not a blind spot: zero lines for Diff. Impressions or Diff. Clicks. `DERIVED_TERMS` held. ✅

All 8 gates are now receipt-green across two compiles. MAPPER LANE v1 banks fully — no PENDING tag needed, because the qa receipts arrived before the ledger line ever landed.

**About "the bank line business":** foo_files.py's `#todo` section is the constitution's ledger — the thing that survives my amnesia between summonings. "Banking" a win means writing it there as an exact line, so no future ride re-derives or re-litigates it. Last turn I emitted a PENDING line for you to hand-paste; you (correctly) didn't, and now the receipts let it land fully-banked in one stroke — as a patch this time, so there's nothing to hand-paste. The patch appends the banked line directly under the existing MAPPER LANE entry.

**Desktop vs Downloads:** you're right that `~/Desktop/` was a bad call — macOS iCloud Desktop sync can silently upload client data, WSL has no real Desktop, and desktops are entropy farms. `~/Downloads/` is more stable cross-platform. But the repo already has a better answer than either: **`Notebooks/Client_Work/`** — it's in `.gitignore` by construction (structural absence, not policy), it's already on your Desktop-4 muscle-memory tab in autognome, and your backup scripts sweep it. The receipts bundle (timestamped TSV + `sheet_map.json`) belongs in `Notebooks/Client_Work/<client>/`. The external-deliverable commands below are corrected accordingly.

**Deliverable adjudication** (is `sheet_map.json` toss-back-able at the sheet owner?): Mostly yes — the `confirmation_contract` block is the star, because it states in plain English what the owner must confirm and why nothing runs until they do. That's the "internalize the pain" payload. **The single weakest field for that audience: the bare `score` floats** (`header.candidates[].score`, `api_candidates[].score`). To a reviewer they're evidence; to a sheet owner, `7.213` is unexplained numerology that undermines the artifact's authority the moment they ask "what's a 7.213?" Don't fix it now — the coachman's veto applies, and the fix (a `--deliverable` rendering that leads with the contract and hides scores) is a later car, after the first real client artifact tells us whether it's even needed. measure.py stays parked until a human-confirmed mapping exists.

One loose end: the newline fix is on disk (receipt proves it) but I see no commit for it in your transcript — the caboose below sweeps it up with the router patch.

---

## 1. PROBES

The first is the 0→1 delta straddling the bank-line patch. The second proves the client-data location is structurally excluded from git before you ever put a client file there. The third confirms the tree is clean after the caboose (the uncommitted W292 fix should be swept in).

```bash
grep -c "MAPPER LANE v1 BANKED" foo_files.py
git check-ignore Notebooks/Client_Work/ && echo IGNORED || echo NOT-IGNORED
git status --porcelain | wc -l
```

## 2. NEXT CONTEXT

```text
! grep -c "MAPPER LANE v1 BANKED" foo_files.py
! git check-ignore Notebooks/Client_Work/ && echo IGNORED || echo NOT-IGNORED
! git status --porcelain | wc -l
scripts/map_sheet.py
scripts/connectors/sheets.py
scripts/connectors/README.md
foo_files.py
```

## 3. PATCHES

One car, foo_files.py only (router churn — `m` will hint it correctly). The SEARCH anchors on the unique closing sentence of the existing MAPPER LANE entry and appends the banked line beneath it:

```text
Target: foo_files.py
[[[SEARCH]]]
Never automate against a spreadsheet without one.
[[[DIVIDER]]]
Never automate against a spreadsheet without one.
# - MAPPER LANE v1 BANKED 2026-07-20 (all 8 gates receipt-green across two compiles): scripts/map_sheet.py completes the scaffold acquisition -> explicit draft mapping -> human confirmation -> judgment. Structural: acquired_at_utc x2 in sheets.py; README downstream-stages seam; AST OK. Behavioral: headers 3/3/3/4 exact; Summary exposed as needs_human (mixed layout never coerced); value-sampled lookup accepted Product URL / Variant URL and REJECTED the numeric "Variant URL rows" trap; Current Impressions/Clicks -> search_console.period_0 fields on all four metric tabs; ZERO Diff correspondences (DERIVED_TERMS held). Receipts bundle (timestamped TSV + sheet_map.json) lives in Notebooks/Client_Work/<client>/ (gitignored by construction, not Desktop/Downloads). Known deliverable weakness: bare score floats read as numerology to sheet owners — candidate --deliverable rendering, only if the first real client artifact demands it. measure.py stays parked until a HUMAN-CONFIRMED mapping exists.
[[[REPLACE]]]
```

Actuation: `patch`, `app`, `d`, `m` — then `blast` as the caboose (it will also sweep the uncommitted `true_schema_discoverer.py` newline fix into the same push).

## 4. PROMPT

```text
Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected receipts:
- "MAPPER LANE v1 BANKED" grep: 0 -> 1 (the ledger line landed).
- Notebooks/Client_Work/ prints IGNORED (client-data location is
  structurally excluded before any client file exists there).
- git status --porcelain | wc -l is 0 (W292 fix and router line both
  committed; no stragglers).

If green, this ride's stated goal is reached: the mapper exists, is
banked, and its receipts bundle has a safe home. Dismount beats apply:
1. VERIFY the article's opening goal (peel out, start with the mapper;
   timestamp the stacked TSVs) against these receipts, not memory.
2. BANK anything still unbanked as exact paste-ready lines.
3. DANGLING: one line each — the --deliverable rendering question, the
   --api-schema discoverer feed (right-hand candidates discovered rather
   than hand-supplied), and the first real client run.
4. SEED the next ride's first compile: adhoc.txt lines for whichever
   dangling item the coachman picks. The client run itself happens
   OUTSIDE the compile lane — client STACK output never rides to a
   cloud chat window unscrubbed.
```

Keep the timestamped TSV beside the JSON forever — that pair, zipped, is the receipts bundle the article promised: the deterministic answer you hand back when someone asks you to proof numbers against an opaque mutation machine.

 # - EARMARK: TWO-GATE 403 DIAGNOSIS (banked 2026-07-20): a Google service-account 403 has two independent causes that clear IN ORDER — SERVICE_DISABLED (API toggle in the key's Cloud project; once per API per project, forever) then PERMISSION_DENIED (resource not shared with client_email; once per document). Conviction: sheets.py's first live LIST died on SERVICE_DISABLED for the key's project while sharing remained untested. Auth is never the blocker when it fits a pattern already on the shelf: four wallet auth kinds cover every connector so far, and each new OAuth is a wallet-hygiene rep, not a delay.
 # - ADVERSARIAL TQM LANE (reordered 2026-07-20 at dismount): acquisition (connectors) -> MAPPING (see MAPPER LANE) -> judgment (measure.py) -> packaging (evidence.py). measure.py v1 + variant_rollup_v1.json were drafted in the sheets-STACK article transcript but deliberately NOT applied — judgment against unmapped columns is judgment against a riddle. Recover the drafts from that article once a mapper exists. evidence.py unstarted.
 # - MAPPER LANE (opened 2026-07-20, coachman-steered): before ANY automation or QA against a client sheet, mint the mapping artifact — sheet_map.json (working name; map-gsheet-columns-to-api-fields-for-qa.json IS the mentality). One entry per tab answering exactly three questions: (1) which row holds the column labels — if unanswerable per tab, the client has the bigger problem and the mapper is the conversation you hand back; (2) which column feeds the API call, addressed by BOTH numeric index and fuzzy name (case-insensitive; tolerate punctuation, abbreviation, hyphenation, parens); (3) which columns get QA'd against which API fields. Left side of the map = the Mutation Machine (riddle); right side = the API (fixed, discoverable three ways: OpenAPI swagger tree walk, datamodel/datasets endpoints via imports/botify/true_schema_discoverer.py, CDP wire sniff). Stable side for this campaign: Botify RealKeywords/search_console, not raw GSC — cross-client, BigQuery-fed, one auth. The mapper is a DELIVERABLE, not plumbing: toss it back at the sheet owner so they internalize the pain. Never automate against a spreadsheet without one.
+# - MAPPER LANE v1 BANKED 2026-07-20 (all 8 gates receipt-green across two compiles): scripts/map_sheet.py completes the scaffold acquisition -> explicit draft mapping -> human confirmation -> judgment. Structural: acquired_at_utc x2 in sheets.py; README downstream-stages seam; AST OK. Behavioral: headers 3/3/3/4 exact; Summary exposed as needs_human (mixed layout never coerced); value-sampled lookup accepted Product URL / Variant URL and REJECTED the numeric "Variant URL rows" trap; Current Impressions/Clicks -> search_console.period_0 fields on all four metric tabs; ZERO Diff correspondences (DERIVED_TERMS held). Receipts bundle (timestamped TSV + sheet_map.json) lives in Notebooks/Client_Work/<client>/ (gitignored by construction, not Desktop/Downloads). Known deliverable weakness: bare score floats read as numerology to sheet owners — candidate --deliverable rendering, only if the first real client artifact demands it. measure.py stays parked until a HUMAN-CONFIRMED mapping exists.
 # - EARMARK: THE COACHMAN'S VETO (banked 2026-07-20): an emitted patch train is a PROPOSAL until the human runs `app`; refusing an entire train costs nothing (no dead cars — nothing was applied) and is the correct move when the strategy beneath it shifts. The Horse has instincts; the coachman has been down the road. Witness: the measure.py train of 2026-07-20, refused at the platform, redirected into the MAPPER LANE.
 # - TODO (ratify wording, then retitle EARMARK): PATCH CAR BUNDLING — a car = one commit story. Bundle blocks into one fenced payload when they form one atomic change deserving one commit message, even across files; split cars when the commits should teach separately (feature vs docs vs constitution flip), so `m`'s message and the human's internalization track each lesson. Evidence: the 2026-07-20 five-block sheets.py car cut the human loop from O(blocks) to O(cars) with zero exact-match failures.
 # - EARMARK: AUTH-KIND RESIDUE (convicted 2026-07-20): sheets.py v1 inherited gsc's service_account plumbing by pattern-proximity, so the API-enablement toggle went to the right console page for the WRONG credential's project — SERVICE_DISABLED persisted post-enablement and only the human caught the identity-model mismatch. Auth kind is a USER-story decision, never nearest-neighbor: Pipulate humans own Google accounts -> oauth_token_file (gmail pattern, per-scope token files, NO sharing gate); unattended robots -> service_account_file. Every connector's identity mode must print its credential's project_id so wrong-project convictions take seconds, not console archaeology.

Wow, the Fable 5 provided next steps feel like the Worm dismount, and that'd be
great. But what I do need is an instruction manual. Explain this to me like I'm
the person on the other end. Also explain it to me like I'm me. I've got this
file, `sheet_map.json`... or maybe I don't. I don't see it in here
`/home/mike/repos/pipulate/Notebooks/Client_Work`. Is there a template or
something? To I make it every time new bespoke. There's an articulation part
remaining. The proof isn't going to be on every tab and every column. I'm going
to make a series of mappings for say Tab 1, 2 and 3. It sets the 1-to-1 stage
but there may be more to come. I'm likely going to do something with date
ranges and you don't have to worry about that now, but I do have to start
visualizing stuff. Can you show me a sample JSON file? Keep Client names out of
it. Like just maybe a few PDPs of colored widgets for client example.com. And
how about some ASCII art diagrams to help us visualize it?

Prompt:

Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected receipts:
- "MAPPER LANE v1 BANKED" grep: 0 -> 1 (the ledger line landed).
- Notebooks/Client_Work/ prints IGNORED (client-data location is
  structurally excluded before any client file exists there).
- git status --porcelain | wc -l is 0 (W292 fix and router line both
  committed; no stragglers).

If green, this ride's stated goal is reached: the mapper exists, is
banked, and its receipts bundle has a safe home. Dismount beats apply:
1. VERIFY the article's opening goal (peel out, start with the mapper;
   timestamp the stacked TSVs) against these receipts, not memory.
2. BANK anything still unbanked as exact paste-ready lines.
3. DANGLING: one line each — the --deliverable rendering question, the
   --api-schema discoverer feed (right-hand candidates discovered rather
   than hand-supplied), and the first real client run.
4. SEED the next ride's first compile: adhoc.txt lines for whichever
   dangling item the coachman picks. The client run itself happens
   OUTSIDE the compile lane — client STACK output never rides to a
   cloud chat window unscrubbed.

🎤

**Fable 5 High**: Context verified.

**Verification against THIS compile's LIVE COMMAND RECEIPTS** (Manifest list: rolling pin, grep, check-ignore, porcelain — four ran):

- `MAPPER LANE v1 BANKED` grep: your hand-run BEFORE showed **0**; this compile's receipt shows **1**. The ledger line landed, delta exact. ✅
- `Notebooks/Client_Work/` prints **IGNORED** — structural exclusion confirmed before any client file exists there. ✅
- `git status --porcelain | wc -l` = **0** — W292 fix and router line both swept, no stragglers. ✅

All green. Dismount granted — four beats:

**1. VERIFY.** The article's opening goal was: peel out, start with the mapper; timestamp the stacked TSVs. Both are receipt-proven, not remembered: `acquired_at_utc` propagates STACK→map (witnessed at 2 in sheets.py and populated in the mapper receipt last compile), and `map_sheet.py` exists, parses, and passed all 8 behavioral gates across two compiles. Goal met.

**2. BANK.** The v1 bank line is already in the ledger (this compile's grep is the receipt). One new graduation rides as the single patch below: the v2 confirmation-schema scope, seeded so the articulation you're asking about never gets re-derived.

**3. DANGLING** — one line each:
- `--deliverable` rendering (hide the score floats): waits for the first real client artifact to demand it.
- `--api-schema` discoverer feed: prove right-hand candidates are *discovered*, not hand-supplied.
- First real client run: happens OUTSIDE the compile lane, in `Notebooks/Client_Work/<client>/`, never rides unscrubbed.
- Date-range parameters: ride the **API side** of a confirmed qa_field later — never the sheet side.

**4. SEED** — in NEXT CONTEXT below.

## The instruction manual you asked for

### As if you're the person on the other end (the sheet owner)

You maintain a spreadsheet that *reports* numbers. Reporting spreadsheets drift the moment they're born — whatever happened to happen to put those numbers there is invisible. So I don't audit your sheet by squinting at it. I **photograph** it: a timestamped snapshot of every tab's actual data rectangle. Then a program reads the photograph and *guesses* your layout — where your header row hides, which column is the URL that joins to the API, which columns claim to be impressions and clicks. Those guesses come back to me as a draft map, and **nothing runs until a human confirms the map.**

If the program can't find your header row, that's not a tooling failure — it's a finding about your spreadsheet, and the map is the conversation I hand back to you. Once the map is confirmed, any number in your sheet can be replayed against the source-of-truth API deterministically. When someone questions your numbers, I don't argue — I send a zip: the timestamped snapshot, the confirmed map, and the API pulls. Feed that zip to any AI and it can adjudicate your numbers without vibes or luck.

### As you (Mike)

**There is no template, and `Client_Work/` is empty because no client run has happened yet.** Both files are *outputs* of a run, not repo assets. `map_sheet.py` IS the template generator — the schema is the constant, every instance is derived fresh from THE sheet in front of you:

```text
  Step 1 — ACQUIRE          Step 2 — MAP              Step 3 — CONFIRM
  (sheets.py)               (map_sheet.py)            (you, in vim)

  client URL ──► STACK ──►  draft sheet_map.json ──►  edit statuses ──►  Step 4 (parked)
               timestamped   "suggested" everywhere    "confirmed" on     measure.py reads
               TSV on disk   status: draft_requires_   tabs 1-3 only;     ONLY confirmed
                             human_confirmation        rest excluded      tabs/columns
```

Concretely: run the two External-Deliverables commands below, then open the JSON and walk tab by tab. Confirm or correct the header row. Confirm the lookup key. For each qa column, collapse the candidate list to **one** `api_field`. Tabs you're not covering get `"mapping_status": "excluded"` — a partial map (Tabs 1–3) is a *valid confirmed map*; downstream consumes only what's confirmed. Flip the top-level status. Done: that pair (TSV + confirmed JSON) is the receipts bundle.

### The three diagrams

The same file after your Step-3 edit — this is the **articulation part**, the v2 shape being seeded today:

```json
{
  "status": "human_confirmed",
  "confirmed_by": "consultant",
  "confirmed_at_utc": "2026-07-20T21:40:00Z",
  "tabs": [
    {
      "tab_name": "Widget PDPs",
      "mapping_status": "confirmed",
      "header": { "status": "confirmed", "row": 3 },
      "lookup_key": { "status": "confirmed", "column_index": 1,
                      "column_name": "Product URL", "api_join": "url" },
      "qa_fields": [
        { "sheet_column_index": 3, "sheet_column_name": "Current Impressions",
          "status": "confirmed", "api_field": "search_console.period_0.count_impressions" },
        { "sheet_column_index": 4, "sheet_column_name": "Current Clicks",
          "status": "confirmed", "api_field": "search_console.period_0.count_clicks" }
      ]
    },
    { "tab_name": "Summary", "mapping_status": "excluded",
      "reason": "presentation layout; not a dataset" }
  ]
}
```

Two invariants worth noticing: candidate *lists* collapse to one *field* on confirmation, and exclusion is an explicit recorded decision, never a silent omission. Date ranges will later attach beside `api_field` (a period parameter) — API side, exactly as you intuited.

## 1. PROBES

The grep is the 0→1 delta straddling the seed patch. The find is a **name-free** count of Client_Work subdirectories (counts only — client names must never ride the compile lane), proving the receipts-bundle home exists before the first real run.

```bash
grep -c "MAPPER LANE v2 SCOPE" foo_files.py
find Notebooks/Client_Work -maxdepth 1 -type d 2>/dev/null | wc -l
```

## 2. NEXT CONTEXT

## 3. PATCHES

One car, foo_files.py only (router churn — `m` will hint it correctly). It seeds the v2 confirmation-schema scope directly under the v1 bank line:

Actuation: `patch`, `app`, `d`, `m`, `blast` as the caboose.

## 4. PROMPT

```text
Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected receipts:
- "MAPPER LANE v2 SCOPE" grep: 0 -> 1 (the confirmation-schema seed landed).
- Client_Work subdirectory count is a bare number, no names (the name-free
  probe held the compile-lane hygiene line).

This is a fresh ride, coachman's choice of dangling item:
(a) the first real client run — walk me through it as operator support,
    receipts staying OUTSIDE the compile lane; or
(b) the --api-schema discoverer feed — prove right-hand candidates are
    DISCOVERED from a bounded true_schema_discoverer artifact rather than
    hand-supplied.
State which is cheaper given the receipts, then emit the full patch train
for it. measure.py remains parked until a human-confirmed mapping exists.
Preserve the coachman's veto.
```

## 5. EXTERNAL DELIVERABLES

Manual, outside version control, never in patch markers — the first-client-run choreography (unchanged from last turn, restated as the standing recipe):

```text
mkdir -p ~/repos/pipulate/Notebooks/Client_Work/<client>
.venv/bin/python scripts/connectors/sheets.py <client-URL> > ~/repos/pipulate/Notebooks/Client_Work/<client>/stack_$(date -u +%Y%m%dT%H%M%SZ).tsv
.venv/bin/python scripts/map_sheet.py ~/repos/pipulate/Notebooks/Client_Work/<client>/stack_*.tsv --api-field search_console.period_0.count_impressions --api-field search_console.period_0.count_clicks -o ~/repos/pipulate/Notebooks/Client_Work/<client>/sheet_map.json
```

Then Step 3 is yours alone: vim the JSON, confirm Tabs 1–3, exclude the rest, flip the status. The TSV + confirmed JSON pair, zipped, is the deterministic answer you hand back when someone asks you to proof numbers against an opaque mutation machine.

**MikeLev.in**: Okay, I have to digest this. I have the parts I need, but I have to put
them together now and it's going to take a stepping back and planning the next
step. But I need to digest this further. Hey ChatGPT Explainer! Explain to me
what's going on here. Bring it down for me. Like when I'm getting ready to use
this as-is walk me through it. Are there parts not built? Things still have to
hit against the API and I have a lot of ideas there to still craft it like
date-ranges for trending and stuff. I think given what we have so far there's
stuff I can run to get that mapping JSON file. What do I do? Where does it go?
Where do I look? Get me that far and I can take it from there.

 # - ADVERSARIAL TQM LANE (reordered 2026-07-20 at dismount): acquisition (connectors) -> MAPPING (see MAPPER LANE) -> judgment (measure.py) -> packaging (evidence.py). measure.py v1 + variant_rollup_v1.json were drafted in the sheets-STACK article transcript but deliberately NOT applied — judgment against unmapped columns is judgment against a riddle. Recover the drafts from that article once a mapper exists. evidence.py unstarted.
 # - MAPPER LANE (opened 2026-07-20, coachman-steered): before ANY automation or QA against a client sheet, mint the mapping artifact — sheet_map.json (working name; map-gsheet-columns-to-api-fields-for-qa.json IS the mentality). One entry per tab answering exactly three questions: (1) which row holds the column labels — if unanswerable per tab, the client has the bigger problem and the mapper is the conversation you hand back; (2) which column feeds the API call, addressed by BOTH numeric index and fuzzy name (case-insensitive; tolerate punctuation, abbreviation, hyphenation, parens); (3) which columns get QA'd against which API fields. Left side of the map = the Mutation Machine (riddle); right side = the API (fixed, discoverable three ways: OpenAPI swagger tree walk, datamodel/datasets endpoints via imports/botify/true_schema_discoverer.py, CDP wire sniff). Stable side for this campaign: Botify RealKeywords/search_console, not raw GSC — cross-client, BigQuery-fed, one auth. The mapper is a DELIVERABLE, not plumbing: toss it back at the sheet owner so they internalize the pain. Never automate against a spreadsheet without one.
 # - MAPPER LANE v1 BANKED 2026-07-20 (all 8 gates receipt-green across two compiles): scripts/map_sheet.py completes the scaffold acquisition -> explicit draft mapping -> human confirmation -> judgment. Structural: acquired_at_utc x2 in sheets.py; README downstream-stages seam; AST OK. Behavioral: headers 3/3/3/4 exact; Summary exposed as needs_human (mixed layout never coerced); value-sampled lookup accepted Product URL / Variant URL and REJECTED the numeric "Variant URL rows" trap; Current Impressions/Clicks -> search_console.period_0 fields on all four metric tabs; ZERO Diff correspondences (DERIVED_TERMS held). Receipts bundle (timestamped TSV + sheet_map.json) lives in Notebooks/Client_Work/<client>/ (gitignored by construction, not Desktop/Downloads). Known deliverable weakness: bare score floats read as numerology to sheet owners — candidate --deliverable rendering, only if the first real client artifact demands it. measure.py stays parked until a HUMAN-CONFIRMED mapping exists.

Auth kind is a USER-story decision, never nearest-neighbor: Pipulate humans own Google accounts -> oauth_token_file (gmail pattern, per-scope token files, NO sharing gate); unattended robots -> service_account_file. Every connector's identity mode must print its credential's project_id so wrong-project convictions take seconds, not console archaeology.

# The whole thing in one sentence

You have built **the camera** and **the labeling machine**.

You have **not yet built the machine that calls the API, compares the numbers, and produces the verdict**.

`map_sheet.py` describes itself as a scaffold for a human-reviewable artifact. Its suggestions are explicitly **not confirmations**, and the JSON must be reviewed before automation or QA uses it. 

## The two humans in this story

### The spreadsheet owner

The spreadsheet owner is not necessarily sloppy or irresponsible. They are using spreadsheets for what spreadsheets are exceptionally good at:

* moving quickly;
* arranging information visually;
* changing labels and formulas;
* collaborating with other people;
* producing something understandable in a meeting.

Their job may be to communicate the numbers, not preserve the forensic history of every number.

### You

Your problem is different.

Someone can eventually ask:

> Where did this number come from?

You cannot responsibly answer:

> There was a spreadsheet, and it looked right.

You need to know:

* which tab contained the number;
* which row contained the column names;
* which column identified the page;
* which API field corresponded to the sheet column;
* which period was requested;
* when the sheet was photographed;
* what assumptions a human confirmed.

The map is the handshake between those two legitimate needs. It turns the spreadsheet owner’s flexible presentation into an explicit contract you can audit.

# The peanut-butter-sandwich instructions

## Ingredients

You need:

1. A Google Sheet URL.
2. A safe client-work directory.
3. `scripts/connectors/sheets.py`.
4. `scripts/map_sheet.py`.
5. The API fields you currently want to recognize.

For the first run, those API fields are:

```text
search_console.period_0.count_impressions
search_console.period_0.count_clicks
```

The mapper also accepts `--api-schema` and `--api-prefix`, but using a discovered schema is a later refinement. The current working path can supply known fields directly with repeated `--api-field` arguments. 

---

## Step 1: Check that the kitchen works

Go to the repository:

```bash
cd ~/repos/pipulate
```

Run the Sheets connector without a spreadsheet:

```bash
.venv/bin/python scripts/connectors/sheets.py
```

That is the identity-and-usage mode. It lets you confirm that the Google authentication plumbing is ready before involving client material. The connector’s documented default mode is identity checking, while passing a URL invokes the timestamped STACK operation. 

---

## Step 2: Choose the plate

Do not expect `sheet_map.json` to appear directly inside:

```text
Notebooks/Client_Work/
```

That directory is the cabinet, not the plate.

Create a subdirectory for the particular engagement:

```bash
client_slug="example-com"
workdir="Notebooks/Client_Work/$client_slug"

mkdir -p "$workdir"
```

The current receipt proves that the `Client_Work` tree exists, but nothing automatically creates a mapping file merely because the directory exists. 

Your eventual layout will be:

```text
Notebooks/Client_Work/example-com/
├── stack_20260720T220000Z.tsv
├── sheet_map.draft.json
└── sheet_map.json
```

---

## Step 3: Put down the first slice of bread

This is the **photograph-the-sheet** step.

Set the sheet URL and create a timestamped filename:

```bash
sheet_url="PASTE_THE_GOOGLE_SHEET_URL_HERE"
stamp="$(date -u +%Y%m%dT%H%M%SZ)"
stack="$workdir/stack_$stamp.tsv"
```

Acquire the sheet:

```bash
.venv/bin/python scripts/connectors/sheets.py "$sheet_url" > "$stack"
```

You now have something like:

```text
Notebooks/Client_Work/example-com/stack_20260720T220000Z.tsv
```

This is not an ordinary spreadsheet export. It is a stacked, tab-delimited snapshot containing:

* the spreadsheet identity;
* an acquisition timestamp;
* each tab’s actual data rectangle;
* clear start and end markers around each tab;
* the tab URL.

That TSV is your original photograph. Do not edit it.

---

## Step 4: Make sure there is bread on the plate

Check that the acquisition produced real tab sections:

```bash
head -n 12 "$stack"
```

Then:

```bash
grep -m 5 '^--- START: TAB' "$stack"
```

You should see output shaped like:

```text
# Example Spreadsheet [spreadsheetId: ...]
# acquired_at_utc: 2026-07-20T22:00:00Z

--- START: TAB "Widget PDPs" (103 rows x 8 cols) ---
...
--- START: TAB "Summary" (14 rows x 6 cols) ---
```

If there are no `START: TAB` lines, stop there. Possible causes include:

* authentication failure;
* access failure;
* an unexpectedly large sheet that triggered the connector’s budget protection;
* an empty or malformed acquisition.

The mapper deliberately refuses input with no sentinel-fenced tabs rather than guessing. 

---

## Step 5: Spread the peanut butter

Now turn that photograph into a proposed map.

Use a draft filename so the machine-produced original survives your later manual edits:

```bash
draft_map="$workdir/sheet_map.draft.json"
```

Run:

```bash
.venv/bin/python scripts/map_sheet.py "$stack" \
  --api-field search_console.period_0.count_impressions \
  --api-field search_console.period_0.count_clicks \
  -o "$draft_map"
```

The program writes exactly where `-o` tells it to write. It does not search `Client_Work`, choose a client, or invent a destination for you. 

Confirm that it exists:

```bash
ls -lh "$stack" "$draft_map"
```

Pretty-print and inspect it:

```bash
.venv/bin/python -m json.tool "$draft_map" | less
```

At this point you have reached the useful stopping point you asked for.

You now possess:

```text
the frozen sheet             stack_<timestamp>.tsv
the machine's interpretation sheet_map.draft.json
```

# What the draft map is telling you

For every tab, the mapper tries to answer three questions.

## Question 1: Where is the header?

Example:

```json
"header": {
  "status": "suggested",
  "row": 3,
  "suggested_row": 3
}
```

Translation:

> “I think row 3 contains the column names.”

If the layout is mixed or ambiguous, it may instead say:

```json
"mapping_status": "needs_human"
```

That is not necessarily failure. It may be an accurate diagnosis that the tab is a presentation surface rather than a rectangular dataset.

## Question 2: Which column identifies the thing being measured?

Example:

```json
"lookup_key": {
  "status": "suggested",
  "column_index": 1,
  "column_name": "Product URL",
  "normalized_name": "product url"
}
```

Translation:

> “Column A appears to contain the URLs that can join these spreadsheet rows to API records.”

It does not rely only on the words `Product URL`. It samples values and checks whether they are actually URLs. That protects you from columns such as:

```text
Variant URL rows
```

when the cells underneath contain counts rather than URLs. 

## Question 3: Which sheet columns might correspond to API fields?

Example:

```json
{
  "sheet_column_index": 3,
  "sheet_column_name": "Current Impressions",
  "status": "suggested",
  "api_candidates": [
    {
      "field": "search_console.period_0.count_impressions",
      "score": 0.81
    }
  ]
}
```

Translation:

> “The spreadsheet’s third column probably claims to contain the API’s current-period impressions.”

Columns containing words such as `Diff`, `Change`, `Delta`, `Prior`, or `Previous` are intentionally kept out of these direct current-period suggestions. 

# Step 6: Make a copy before touching it

Preserve the machine’s original answer:

```bash
confirmed_map="$workdir/sheet_map.json"
cp "$draft_map" "$confirmed_map"
```

Now edit:

```bash
vim "$confirmed_map"
```

The two files have different jobs:

```text
sheet_map.draft.json   What the machine suggested
sheet_map.json         What the human eventually approved
```

That distinction is worth preserving even though the current design only requires a confirmed map downstream.

# Step 7: Perform the human confirmation

This portion is **not automated yet**.

The currently banked convention says that a confirmed map is the draft edited by hand. It allows you to confirm only Tabs 1–3 and explicitly exclude everything else. Each confirmed QA column should resolve to one API field, and date-range semantics will later attach on the API side. 

You make five kinds of edits.

## A. Confirm the whole document

Change:

```json
"status": "draft_requires_human_confirmation"
```

to something like:

```json
"status": "human_confirmed",
"confirmed_by": "consultant",
"confirmed_at_utc": "2026-07-20T22:30:00Z"
```

## B. Confirm or exclude each tab

A tab you intend to use:

```json
"mapping_status": "confirmed"
```

A tab you are deliberately not covering:

```json
{
  "tab_name": "Executive Summary",
  "mapping_status": "excluded",
  "reason": "Presentation layout; not part of this QA pass."
}
```

This means a partial map is valid.

You do not have to map the entire workbook just because the workbook contains twelve tabs.

## C. Confirm the header

Change the selected tab’s header to:

```json
"header": {
  "status": "confirmed",
  "row": 3
}
```

You are saying:

> “Yes. I inspected the tab. Row 3 really is the header.”

## D. Confirm the lookup key

Change it to something like:

```json
"lookup_key": {
  "status": "confirmed",
  "column_index": 1,
  "column_name": "Product URL",
  "normalized_name": "product url",
  "api_join": "url"
}
```

You are saying:

> “This is the column that connects a spreadsheet row to an API entity.”

## E. Collapse each API candidate to one answer

Draft:

```json
{
  "sheet_column_index": 3,
  "sheet_column_name": "Current Impressions",
  "status": "suggested",
  "api_candidates": [
    {
      "field": "search_console.period_0.count_impressions",
      "score": 0.81
    }
  ]
}
```

Confirmed:

```json
{
  "sheet_column_index": 3,
  "sheet_column_name": "Current Impressions",
  "status": "confirmed",
  "api_field": "search_console.period_0.count_impressions"
}
```

The machine offers candidates.

The human chooses one.

# What is built versus what is still missing

## Built now

You can currently:

* authenticate to Google Sheets;
* acquire a timestamped snapshot;
* save it outside version control;
* detect tabs and probable header rows;
* identify plausible URL lookup columns;
* reject URL-looking column names whose values are not URLs;
* propose mappings from sheet columns to known API fields;
* generate a real `sheet_map.draft.json`;
* manually produce a partial confirmed map.

The code emits the top-level draft status and a confirmation contract requiring review of the header, lookup key, and API correspondences. 

## Not built yet

You do **not** yet have:

* an editor or wizard for confirming the JSON;
* a validator for the manually confirmed v2 shape;
* the actual API retrieval stage;
* `measure.py` performing comparisons;
* date-range selection;
* trending calculations;
* discrepancy classifications;
* automated evidence ZIP packaging;
* a polished sheet-owner-facing rendering that hides internal matching scores.

The project ledger explicitly parks `measure.py` until a human-confirmed map exists and describes packaging as still unstarted. 

# Where date ranges eventually belong

Your instinct about date ranges is correct, but they do not belong in the sheet-layout portion of the map.

This:

```json
"sheet_column_name": "Current Impressions"
```

describes what the spreadsheet claims.

This future material:

```json
"api_query": {
  "field": "search_console.period_0.count_impressions",
  "start_date": "2026-06-01",
  "end_date": "2026-06-30"
}
```

describes how the source-of-truth API should be queried.

That belongs beside the confirmed API field. It should not be inferred from spreadsheet geometry unless the human explicitly confirms the period semantics.

# The practical stopping point

For your immediate next session, do only this:

```bash
cd ~/repos/pipulate

client_slug="example-com"
sheet_url="PASTE_THE_GOOGLE_SHEET_URL_HERE"
workdir="Notebooks/Client_Work/$client_slug"
stamp="$(date -u +%Y%m%dT%H%M%SZ)"
stack="$workdir/stack_$stamp.tsv"
draft_map="$workdir/sheet_map.draft.json"

mkdir -p "$workdir"

.venv/bin/python scripts/connectors/sheets.py "$sheet_url" > "$stack"

grep -m 5 '^--- START: TAB' "$stack"

.venv/bin/python scripts/map_sheet.py "$stack" \
  --api-field search_console.period_0.count_impressions \
  --api-field search_console.period_0.count_clicks \
  -o "$draft_map"

ls -lh "$workdir"
.venv/bin/python -m json.tool "$draft_map" | less
```

When that completes, look here:

```text
~/repos/pipulate/Notebooks/Client_Work/example-com/
```

Your first goal is simply to see:

```text
stack_<timestamp>.tsv
sheet_map.draft.json
```

Then read the JSON and ask, tab by tab:

Did it find the right header?
Did it find the right URL column?
Did it propose the right API field?
Do I want this tab included at all?
```

That is the whole sandwich you can make today. The API comparison engine is the next recipe, not a missing ingredient you need before generating and understanding the map.

**No repo patches are required for this step.**

**MikeLev.in**: Okay, this is another good transition article with a good
take-off ramp for the next round coming right up! Hey AI Editor, make sure you
focus on what really is occurring in this article and not about the article
coming after. This is a stepping stone on a larger project and a larger general
workflow of accompanying deliverables with full audit trails.

Let's try using this thing per those How to Make a Peanut Butter Sandwich
instructions.

```bash
$ git status
On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean
(nix) pipulate $ .venv/bin/python scripts/connectors/sheets.py
# sheets.py — read-only Google Sheets gateway (OAuth: your own account)

credentials : /home/mike/.config/pipulate/credentials.json  [present]
project_id  : work-integrations-500916
token       : /home/mike/.config/pipulate/sheets_token.json  [minted]

# Next: python scripts/connectors/sheets.py "https://docs.google.com/spreadsheets/d/<ID>/edit"   (LIST tabs + sizes)
(nix) pipulate $
```

Yes! This is the most important part. I now have the ability to just pull in
Google Sheets into these compiled contexts. We follow the same tiny Unix command
rule as every other tool and start this rapid process of cranking out
connectors. The first call to them always produces documentation that shows how
to make the easiest next call which should always be able to be done directly
by hand to confirm.

WOW! It totally friggin does and for that alone the time I put in on it. That's
just amazing! I've got to let that internalize for a minute. I know there's
other more complicated stuff here to do an actual analysis, but this alone is
worth the price of admission. Let me get this down straight. It's this feeling
of control and 100% clarity that's important here.

Okay, you can see we have the connector we need. Given this Google Sheet
document ID, give me something that will fill in tabs 1, 2 and 3 with sample
data. Make it just ephemeral so I can paste it into the terminal. Use `/tmp/` if
you need to. If the OAuth token is select-only we can change it. I'll need to do
stuff like this from time to time.

Use this URL / doc key

**Fable 5 High**: Context verified.

The scope wall is the one real obstacle: your minted token is `spreadsheets.readonly`, and per your own wallet rule (token files are scope-scoped; one connector must never poison another's), we don't upgrade that token — we mint a **separate read-write token** at `~/.config/pipulate/sheets_rw_token.json`. Same `credentials.json`, same Cloud project (`work-integrations-500916`, Sheets API already enabled from the readonly lane — no console work needed). First run opens the browser once; `sheets_token.json` stays untouched, so your readonly connector keeps working exactly as before.

The sample data is deliberately not random: it recreates the fixture geometry your mapper was convicted against — banner on row 1, blank row 2, **header on row 3**, a real URL lookup column, `Diff.` derived columns, and the numeric `"Variant URL rows"` trap on Tab 3. So seeding this sheet gives you a full end-to-end rehearsal target: `sheets.py` STACK → `map_sheet.py` → draft JSON, on a sheet you own, with zero client data.

Paste this whole thing into your terminal (heredoc is quoted, nothing expands):

```bash
cat > /tmp/seed_sheet.py << 'EOF'
#!/usr/bin/env python3
"""Ephemeral seeder: fills tabs 1-3 of the target sheet with fictional
example.com widget data shaped to exercise map_sheet.py (header row 3,
URL lookup column, Diff. derived columns, numeric 'Variant URL rows' trap).
Uses its OWN read-write token so the readonly connector token is never touched."""

First run pops the browser for the one-time RW consent; every later run of this (or any future seeder reusing that token) is silent. `valueInputOption: RAW` keeps the numbers as literal strings so the STACK snapshot round-trips byte-faithfully into the mapper's `NUMBER_RE`.

---

## 1. PROBES

The first proves the RW token minted beside (not over) the readonly token. The second is the round-trip falsifier: the readonly connector must now STACK three named tabs. The third is the full-circle mapper receipt — it must find header=3 on all three tabs, accept `Product URL` and `Variant URL` as lookups, and reject the numeric `Variant URL rows` trap, on data *you* wrote seconds ago.

```bash
ls -la ~/.config/pipulate/sheets_token.json ~/.config/pipulate/sheets_rw_token.json
.venv/bin/python scripts/connectors/sheets.py 1m5bjmzgaBmSVX465-p6G7EIycOI3C9oz83DBKsO2alE

```

```

## 3. PATCHES

No repo patches required — the seeder is deliberately ephemeral (`/tmp/`), and the RW token path is a wallet fact, not code. If "write access from time to time" graduates into a standing need, the future car is a `--rw` identity in `sheets.py` plus a wallet-descriptor entry for `sheets_rw_token.json` — but that waits for a second real use, per the coachman's veto.

## 4. PROMPT

```text
Verify against THIS compile's LIVE COMMAND RECEIPTS only.

Expected receipts:
- Both token files exist side by side (sheets_token.json readonly untouched;
  sheets_rw_token.json newly minted) — the scope-poisoning rule held.
- STACK shows exactly three tabs: Product Rollup, Top Variant URLs,
  Category Breakdown, each with acquired_at_utc and sentinel fences.
- Mapper receipt: all three tabs ready_for_review with header=3;
  lookup=Product URL on tab 1, Variant URL on tab 2, None on tab 3
  (the numeric "Variant URL rows" trap rejected on fresh live data).

If green, this is the first full write->acquire->map round trip on a sheet
we control end to end. Adjudicate: is this fixture sheet worth banking as
the standing rehearsal target for MAPPER LANE v2 (the human-confirmation
schema), i.e. should the next ride be hand-confirming THIS sheet's
sheet_map.json into the v2 shape as the worked example? If yes, emit the
adhoc lines and choreography for that confirmation ride. If the wallet
should also gain a sheets_rw descriptor entry, say so as a one-line
external deliverable, not a patch. Preserve the coachman's veto.
```

## 5. EXTERNAL DELIVERABLES

Manual, outside the repo: after the probes go green, optionally add one line to `~/.config/pipulate/connectors.json` documenting the new credential — name `sheets_rw`, kind `oauth_token_file`, token path `~/.config/pipulate/sheets_rw_token.json`, scope `spreadsheets` (full), consumer "ephemeral seeders / write utilities." Names and paths only, never values — that's the wallet-hygiene rep that keeps left hand and right hand reading the same illuminated page.

OMG, wow. That's just a little too cool again. This is going to pay back bigtime
when requests like this come up. Almost for this alone, it's worth it. The other
stuff is a bit complicated in comparison and I don't think I really necessarily
need all this auto-guessing stuff. The source of truth is always going to be
what's pulled from the API. So the next thing that happens in the terminal is
this:

```text
sheet_url="PASTE_THE_GOOGLE_SHEET_URL_HERE"
stamp="$(date -u +%Y%m%dT%H%M%SZ)"
stack="$workdir/stack_$stamp.tsv"
```

Which is this:

```bash
(nix) pipulate $ sheet_url="1m5bjmzgaBmSVX465-p6G7EIycOI3C9oz83DBKsO2alE"
stamp="$(date -u +%Y%m%dT%H%M%SZ)"

Well, that was fun. I think I am going to be able to do this. This is very good

Yeah, that works. This sets the stage great going from Google Sheets to per-URL
confirmation against an API. It's amazing how it mapped the fields so properly
against the Botify API.

## Book Analysis

### Ai Editorial Take
What is most compelling here is the tactical use of 'failure' as a feature. By making the mapper explicitly report 'needs_human' when a layout is mixed, the system forces the consultant to confront the client's reality rather than silently producing a 'good enough' wrong answer. It is a masterful application of structural honesty.

Stop guessing where spreadsheet numbers come from. My latest blueprint shows how to build an AI-ready audit trail using timestamped snapshots and human-verified mappings. https://mikelev.in/futureproof/spreadsheet-audit-blueprint/ #DataIntegrity #AIWorkflow #WebAudit
```

### Title Brainstorm
* **Title Option:** A Blueprint for Auditing Opaque Spreadsheets with AI
  * **Filename:** `spreadsheet-audit-blueprint.md`
  * **Rationale:** Direct, professional, and highlights the shift from opacity to transparency.
* **Title Option:** Ending Spreadsheet Drift with Deterministic Mapping
  * **Filename:** `ending-spreadsheet-drift.md`
  * **Rationale:** Focuses on the core technical problem addressed by the methodology.
* **Title Option:** From Mutation Machine to Evidence Bundle
  * **Filename:** `mutation-machine-evidence.md`
  * **Rationale:** Emphasizes the outcome of the process: converting a messy sheet into a valid evidence package.

### Content Potential And Polish
- **Core Strengths:**
  - Clearly defines the roles of machine mapping vs. human judgment.
  - Introduces the 'evidence bundle' concept for client deliverables.
  - Practical and repeatable CLI-based workflow.
- **Suggestions For Polish:**
  - Include a visual example of the confirmation JSON structure.
  - Elaborate on the 'coachman's veto' to highlight the human-in-the-loop maturity model.
  - Add a troubleshooting section for common Google Sheets API access issues.

### Next Step Prompts
- Design the logic for `measure.py` that handles the comparison between the confirmed mapping and the live API data.
- Draft the 'receipts bundle' packaging script that Zips the timestamped TSV and the confirmed JSON.
