Record: Adopt the shared rules

Outcome

This project now pins the shared rules at 2026-10-22.12. rules.lock holds the version and a SHA-256 per vendored file, scripts/rules-check.sh verifies the copy, and tests/16-rules-pin.sh runs it in the suite.

The adoption was breaking: the contract gains a non-overridable safety precedence level, modification becomes authorization-based, and nine capability conventions apply. Conformance cleared 25 findings across five features and one task, and produced 85 requirement identifiers — by far the largest requirement set adopted so far.

Decisions

• Requirement identifiers had to be written, not prefixed. Four features carried their requirements as * prose bullets with no identifiers at all, and one carried two separate ## Requirements headings. The bullets became - \PREFIX-R###` — …:PROBE-GEN-R001–R013,BLOCK-COLLECT-R001–R029,PROBE-OBSERVE-R001–R013,PROBE-CHARACTERIZE-R001–R022, plusSITE-BUILD-R001–R008`. No requirement sentence was rewritten.
• The second Requirements heading became a subsection. ## Requirements (RDAP enrichment) is now ### RDAP Enrichment inside the single ## Requirements section, so its twenty-nine bullets are part of the requirement set the validator reads rather than a section it skips.
• External inputs left the feature graph in three features: the probe and block files under dataflow.out/ were listed as ## Dependencies, which the validator reads as feature dependencies. They moved to ## External Inputs.
• Two tests were renumbered. The project had tests/09-block-map.sh and tests/10-probe-report.sh, which collided with the vendored 09-prompt-contract.sh and 10-prompt-validator.sh — two tests numbered 09, two numbered 10, contradicting the band the shared tests/README.md documents. They are now 14-block-map.sh and 15-probe-report.sh. Only a records/ file names the old paths, and it is a record of what happened.
• The pin test is 16-rules-pin.sh. Every slot in the 00–09 band was already taken, so the usual rule — lowest free slot in that band — had no room; the pin test took the next free number overall.
• PHASES.md is declared in prompts/10-project.md.
• Deleted three stale common/ files and pointed the glossary’s DELTA entry at contract section 6.

Verification

• rules-conform: nothing to conform.
• rules-check: ok (v2026-10-22.12, 39 files, 0 deviations).
• make test: 17 tests, all passed.

Behavioral evidence

Not run. The six eval cases need scripts/status.sh or scripts/site-state-fetch.sh; this project carries neither, so only 01-malformed-task-refusal applies. The portability gap is recorded in 00-project-rules/documents/eval-portability.md.

What this adoption cost the library

Nothing — the fifth consecutive adoption to need no shared-rules change.
