The loop's toolbox: one capture posture, pinned; the ritual, saved - #79
Conversation
The desk-clean before the next loop iterations — no cells, no ticks, and the one hazard the two merged rungs surfaced is closed: probes used to copy the bake's Chromium posture by hand, so a posture change could silently diverge what a probe measures from what the cells bake under. Now the posture is one module (chromium_capture.ts) imported by both the baker and the new probe harness, and it is provenance: oracle-bake.json records its sha256 and the Rust gate refuses a stale one. The proof the extraction is byte-faithful is the rebake itself — all 206 committed oracles verified unchanged through the refactored baker. The rest is friction removal with refusal built in: add_cell.py registers a fixture and its sorted manifest entry (refusing overwrites, duplicate ids, non-kebab names, non-SVG bodies); the justfile carries the bake/gate/ status/probe/add incantations (nvm sourced only where it exists); the pre-landing verification ritual becomes the saved verify-rung workflow (.agents/workflows, .claude symlink per the skills convention), whose first execution verified this very change — and whose first launch attempt caught its own args-delivery bug, which is what the ritual is for. Probe matrices stay scratch by law; only mechanics are committed.

Do not expose or execute conformance verification before the required ratification is recorded. The saved workflow and the gate recipe both produce conformance results, while the supplied checklist context states that the governing rule is not yet ratified. Per repository policy, gate these entry points on the ratification record or defer them until ratification exists.

Validate the standalone SVG and dimensions before writing files.
A comment such as <!-- <svg --> passes the current source check. Zero or negative dimensions also pass. The command then writes an invalid fixture and manifest entry. Require a parseable SVG root element and positive dimensions before either write.

The desk-clean between checklist-loop iterations — no cells, no ticks, zero engine code (one provenance assert is the only Rust change).
The hazard this closes
Probes copied the bake's Chromium capture posture by hand (#77, #78 both did). A posture change would silently diverge what a probe measures from what the cells bake under — a measurement taken under the wrong conditions is the believed-wrong-answer class the repo laws exist to prevent. Now:
chromium_capture.tsis the one posture, imported by bothbake_chromium.tsand the newprobe_harness.ts(scratch probes shrink to a data matrix).oracle-bake.jsonrecordscapture_module_sha256and the Rust gate refuses a stale one.The friction removals

Its first execution verified this very change, and its first launch attempt caught its own args-delivery bug — which is what the ritual is for.Probe matrices stay scratch by law; only mechanics are committed. README gains a Tooling section stating all of this.
Verification: two judges via the saved workflow — repro pass (independent rebake no-op, probe re-run, hash triangulation, add_cell refusals), audit one should_fix (the nvm guard) + wording notes, all applied.
