Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
make_synthetic_twinGenerate a SYNTHETIC TWIN of a real Excel workbook at `path`, written to `out`. Schema (sheets, headers, column types, true row counts) is preserved; every data value is freshly FAKED — no real value is copied. Reason and write your analysis code against the twin; then run it on the real file with run_on_real. Returns the schema summary (safe shape).
redact_textReturn `text` with detected PII replaced by <TYPE> placeholders (e.g. <AU_TFN>, <PERSON>). Deterministic; checksum-validated identifiers and context/precision rules apply so bare numbers are not over-masked. `entities` is an optional PATH to a local `.obsify.entities` file of KNOWN names to hide; matches (incl. variants) are masked as <KNOWN_ENTITY>. If omitted, a nearby `.obsify.entities` is auto-used.
run_on_realCOMPUTE-TO-DATA: execute your Python `code` LOCALLY against the real file at `data_path` (bound to the variable DATA_PATH in your code); the returned `output` is size-capped and **best-effort** PII-masked. The data never enters your context; substance never leaves. **Return AGGREGATES (counts/sums/summaries) via print()** — output masking is defense-in-depth, NOT a guarantee (NER can miss a name in a raw record), so never print raw records or identifiers. The `masking` field carries this caveat with the result. Network is disabled and a timeout applies.
scan_piiScan a file or folder for PII and return TYPES + LOCATIONS + COUNTS only — never the detected values. Safe to surface to an LLM: it learns what PII exists and where, without the substance entering context. Recurses into subfolders; skips unreadable files and caps very large sheets, reporting both as notes. `entities` is an optional PATH to a local `.obsify.entities` file (one name per line) of KNOWN names to hide; matches (incl. suffix/abbreviation variants) are reported as KNOWN_ENTITY. If omitted, a nearby `.obsify.entities` is auto-used. The names are read locally and never returned.
verify_value_freeFail-closed check that `text` contains NONE of `terms` (nor their suffix-normalized / distinctive-token variants). Returns {"value_free": bool} with zero detail on what matched — for verifying an artifact before it leaves the perimeter.
