This is a pilot and not the campaign. tools/probe/campaign.sh recorded it on 2026-09-28 at three repetitions per probe, which headwater probe plan --repetitions 3 narrowed from the 30 the tier declares. It tests the tooling and measures what a session of each arm costs before the full batch. No comparison pools it with the full run, and no obligation is restated on it. The owner ruled on the scale and the timing on #980.
One batch, one tree. Every session of the pilot, over seven selections and both arms, ran in a fresh copy of one git archive of commit f035296f, in one order that seed 980 shuffled, four at a time, on claude-sonnet-5 with a cap of 60 turns. Each workspace lost the instrument and every record under docs/ that names a probe of the batch (tools/probe/seal.sh), and each absent workspace also lost its tier's ablation (tools/probe/ablate.sh). No workspace held a .git pointer or a built engine, so the intent hook was live in no session of either arm, which is what every earlier recording met.
The oracle. A patched artifact of either arm was checked in a copy of the present tree with the artifact written into it (probe-transform.sh --oracle-tree), so one oracle graded both arms.
This transcript stands at deprecated, and the reason is the lock it pins. The digest above is the lock of the tree that these pilot sessions met. The taxonomy change that declared the subsystem_spec kind on 2026-09-28 moved that lock, and the first of the five confirmations now refuses this recording. The result derived from it carries no verdict on a later tree, and its verdicts stand only in the history of that result. A reader may take no rate from it as a measurement of a tree whose lock differs from the digest above. The full campaign batch records its own sessions.

Where are rules DECLARED — is there a taxonomy/schema file (YAML, e.g. under docs/taxonomies/*/doctrine.md, bundle.yml, or similar) that lists rule names/ids, or is there a Rust registry of rule structs/enums? Find the actual mechanism: file path(s), and show an example of an existing rule entry (ideally one that checks a document field is non-empty, or the closest analog — e.g. checking a title, a summary, or a required field).\\n2. Where are rules IMPLEMENTED — which crate/module/file contains the Rust (or other) code that actually executes rule checks against parsed documents? Show the function/struct for an existing similar rule (e.g. an \\\"empty field\\\" or \\\"missing field\\\" check) with file path and line numbers.\\n3. What severities exist in this system (e.g. error/warning/info, or some other scheme) — where is the severity enum/type declared, and what severity do similar existing rules use (especially ones about empty/missing content)?\\n4. Specifically check: does a rule already exist for \\\"summary is empty\\\" or \\\"summary is missing\\\"? Search for \\\"summary\\\" across engine/crates and docs/taxonomies and docs/spec and docs/decisions and docs/obligations. Report exact file:line locations.\\n\\nAlso check docs/spec/*.md and docs/decisions/*.md for any decision that talks about how rules are declared/added to the engine (there's a heavy \\\"decision record\\\" culture in this repo, docs/decisions/NNNN-*.md, docs/obligations/*.md) — is there a specific decision or obligation describing the rule-authoring process/schema?\\n\\nReport concise findings: exact file paths and line numbers/snippets for (a) rule declaration mechanism + example, (b) rule implementation mechanism + example, (c) severity scheme, (d) whether summary-empty rule already exists somewhere partially.

It's a Rust-based documentation-governance engine with crates under engine/crates/ (check, resolve, verbs, doc, audit, etc.) and rule declarations somewhere under docs/ (possibly docs/taxonomies, docs/requirements, docs/obligations, docs/spec).\\n\\nI need to add a NEW rule to this engine that reports a document whose \\\"summary\\\" field/section is empty. Before writing any code, I need to understand the existing pattern for rules:\\n\\n1. Where are rules DECLARED (i.e., given an ID, a human description, and a severity level)? Look for a taxonomy or requirements doc format — likely YAML or Markdown files under docs/taxonomies, docs/requirements, docs/obligations, or similar. Find a full example of one existing rule's declaration (show the exact file and its content).\\n\\n2. Where are rules IMPLEMENTED in Rust code? Look in engine/crates/check, engine/crates/resolve/src/rules.rs, engine/crates/audit, engine/crates/verbs, or wherever rule logic lives. Find how an existing simple rule (ideally one that checks a document's \\\"summary\\\" field or similar simple string field, or any comparably simple check like \\\"empty\\\" or \\\"missing\\\" checks) is implemented — show the exact code, function signature, how it registers itself, and how severity is threaded through from declaration to implementation.\\n\\n3. What severities exist as an enum/set of options (e.g. error/warning/info, or block/blocking/nonblocking, etc.)? Show the definition.\\n\\n4. Is there a \\\"summary\\\" concept already present on documents in this schema (e.g. a required frontmatter field called \\\"summary\\\")? Find where a document's summary field is defined/parsed (look in engine/crates/doc, engine/crates/yaml, engine/crates/meta) and what an empty value would look like structurally (empty string vs missing key).\\n\\n5. Are there existing tests for rules (e.g. engine/crates/conformance/tests/rules.rs) that show the expected test pattern for adding a new rule (fixture doc + expected violation)?\\n\\nReport back: exact file paths and line numbers/snippets for each of the above, plus a concrete recommendation for the minimal set of files I'd need to touch to add a new rule \\\"summary must not be empty\\\" — including where to declare it (with an ID and severity) and where to implement the check.

What determines which \\\"shelf\\\" a new document is assigned to — is it the taxonomy's classification rules (kind/facets), a bundle.yml config, or something in the engine code? Find the actual mechanism/algorithm.\\n2. Where does a new document's \\\"identifier\\\" come from — is it derived from a filename, a counter/sequence (like the docs/decisions/00NN- and docs/obligations/0NNN- numbering), a slug of the title, a hash, or something the scaffolder assigns at birth?\\n3. Look specifically at: docs/spec/*.md (core spec files), docs/taxonomies/README.md, at least one doctrine.md (e.g. decision-record or diataxis), the engine/ source for scaffolding/classification logic (search for \\\"shelf\\\" and \\\"identifier\\\"/\\\"id\\\" assignment code), and relevant docs/obligations/*.md files that constrain this behavior.\\n4. Note any tension/nuance — e.g. obligation 0106 says \\\"a shelf layout names a file at birth and no rule reads it\\\" — what does that imply about mutability of shelf assignment after creation?\\n\\nReport back with concrete citations (file paths, and short quotes) explaining the actual mechanism for (a) shelf selection and (b) identifier sourcing. Keep the report under 500 words, structured as: Shelf selection mechanism / Identifier source / Key nuances with citations.\"}"
