Development record

itd-188 review consistency findings: spc-66 maps acceptance criterion 2 to TestReadingAndScribeSessionsAreDistinctRecords in internal/core/history, which the build neither adds nor declares dropped (deliver it or amend the mapping to say the criterion is procedural); 05-prompt-quality.md still counts ten prompts and six outside the roster after the eleventh landed; the guard test duplicates indexTokenRe and a readRepoFile helper, carries a control that compares a literal to itself, and repeats the canary presence checks the contract rule already runs; the canary's manifest path does not match spc-58's manifest home.
