Green is computed by the harness: it means a machine-checkable predicate was evaluated against the cited record and held. Model prose is never green. The signing key is held in the OS keychain of the machine that produced this bundle. A signature proves the bundle was not altered after it left that machine; it does not prove the machine was honest while producing it.

Claims

VERIFIED

facts.exitCode == 0

cites record 25, tool-call, asserted against tool-call:shell

the harness evaluated the predicate against the cited tool-call:shell record and it held

unverified prosenode --test src/slugify.test.mjs passed all 3 tests including the new whitespace-collapsing and non-alphanumeric-stripping cases.

task: Make slugify collapse runs of whitespace and strip characters that are not letters, digits or hyphens, so " Hello, World! " becomes "hello-world". Add tests for those cases.

Before you edit anything, call declare_file_set with the files you intend to touch: a change to a file outside that set fails the file-set gate. If the work turns out to need another file, call amend_file_set with a reason a reviewer will read. Read before you edit. Make the smallest change that satisfies the task. Every tool result ends with an [evidence record sha256:... kind ...] trailer naming the ledger record it produced and what kind of record it is. To assert that work is done, call the claim tool with a predicate over such a record, the record digest, and that record kind: for example predicate \"facts.exitCode == 0\" with recordKind \"tool-call:shell\", citing the record of the test command you ran. A claim whose kind does not match the record it cites renders UNVERIFIED, so a predicate that happens to hold against some other record never stands in for the one you are claiming about. The harness evaluates the predicate and decides the verdict; your prose never counts as a result. When the work is done, reply with a summary and no tool calls. Quality gates then run against the workspace. If one fails you will be given its raw output and asked to fix it. Fixes are measured: removing tests, removing assertions, adding skip markers, or lowering coverage of the lines you changed gets the attempt rejected outright.",

Before you edit anything, call declare_file_set with the files you intend to touch: a change to a file outside that set fails the file-set gate. If the work turns out to need another file, call amend_file_set with a reason a reviewer will read. Read before you edit. Make the smallest change that satisfies the task. Every tool result ends with an [evidence record sha256:... kind ...] trailer naming the ledger record it produced and what kind of record it is. To assert that work is done, call the claim tool with a predicate over such a record, the record digest, and that record kind: for example predicate \"facts.exitCode == 0\" with recordKind \"tool-call:shell\", citing the record of the test command you ran. A claim whose kind does not match the record it cites renders UNVERIFIED, so a predicate that happens to hold against some other record never stands in for the one you are claiming about. The harness evaluates the predicate and decides the verdict; your prose never counts as a result. When the work is done, reply with a summary and no tool calls. Quality gates then run against the workspace. If one fails you will be given its raw output and asked to fix it. Fixes are measured: removing tests, removing assertions, adding skip markers, or lowering coverage of the lines you changed gets the attempt rejected outright.",

Before you edit anything, call declare_file_set with the files you intend to touch: a change to a file outside that set fails the file-set gate. If the work turns out to need another file, call amend_file_set with a reason a reviewer will read. Read before you edit. Make the smallest change that satisfies the task. Every tool result ends with an [evidence record sha256:... kind ...] trailer naming the ledger record it produced and what kind of record it is. To assert that work is done, call the claim tool with a predicate over such a record, the record digest, and that record kind: for example predicate \"facts.exitCode == 0\" with recordKind \"tool-call:shell\", citing the record of the test command you ran. A claim whose kind does not match the record it cites renders UNVERIFIED, so a predicate that happens to hold against some other record never stands in for the one you are claiming about. The harness evaluates the predicate and decides the verdict; your prose never counts as a result. When the work is done, reply with a summary and no tool calls. Quality gates then run against the workspace. If one fails you will be given its raw output and asked to fix it. Fixes are measured: removing tests, removing assertions, adding skip markers, or lowering coverage of the lines you changed gets the attempt rejected outright.",
