fix(bus): contain requirement quotes and refresh continuation state (#797)

@@ -6207,3 +6207,10 @@ After: preserve the scalar task requirement schema and fail-closed coverage gate
 Before: branch fix/mvp3-req-texts-797 off 62bece4a9da803d0734b435d157578ea5c8d2001 (planning-gate fix) in the T3 worktree; coder/reviewer could not read the product's approved requirement records (D3), and list_requirements remains PM/CTO-only by row 90 (#1584), asserted unchanged by packages/harness/tests/tools.test.mjs. Scope chosen by the lead: no role/tool widening; the bus itself quotes the task-cited approved texts into the implementation/review continuations it already sends.
 
 After: broker #continuationQuote resolves, host-side and never from model input, this request's task.created citations (same product, exact approved snapshot) through the same catalog resolver behind the scoped requirements verb (#requirementsFor), bounding titles+texts at CONTINUATION_QUOTE_BUDGET=16384 bytes with a truncation+ask-PM line. request-continuation renders the block for push_working/review_verdict only, framed as quoted owner-approved data, never instructions; intents/evidence digests unchanged (quote lives in the message body only). request-lifecycle resolves the quote before its journal transactions (resume path; advance reuses the pre-transaction catalog.resolve result, covering the review→implementation changes loopback). Unresolvable or revoked snapshots and missing citations degrade to an ask-PM line without blocking or throwing. roles/coder.md and roles/reviewer.md gained one duty note each; no roles/*.json, tools.mjs gate, schema or authority change. New regressions: exact text/snapshot/records-commit/task citation with foreign-request, foreign-product and unknown-id isolation on a fresh send; reviewer quote; stale-drift and revoked-snapshot fallbacks without throw; budget truncation ordering. Whole files: bus+tasks 197 pass/0 fail/0 skip; harness+business 110 pass/0 fail/0 skip (Row 90 assertion green, coder/reviewer still lack list_requirements); adjacent recovery/limits/cli-lifecycle/launch 45 pass/0 fail/0 skip; 352 total, git diff --check clean. Initial runs failed three new tests ([draft] status not in snapshot rows; append-only request_snapshots/events triggers; successor reuses a waiting unroutable message) — corrected the tests, not the guards. Receipts: /mnt/storage/scratch/mosaic-lead/mvp3/req-texts-*.tap and req-texts-fix-r1-report.md. No push, merge, runtime write or product-acceptance claim.

+## 2026-11-05 — MVP 3 D3 requirement continuation texts, implementation R2 (#797)
+
+Before: exact R1 baseline 6e5cf26e7 on the owner-authorized fix/mvp3-req-texts-797 worktree. Independent review returned CHANGES: approved titles/bodies could forge PM/system/continuation lines, and catalog lookup could invalidate approval while resume dispatched obsolete implementation state. Corrected negative control ran the whole continuation file against unchanged production: 31 pass / 7 fail / 0 skip, including all four hostile coder/reviewer field cases and one persisted obsolete revision-7 coder message. Initial hostile fixtures included forbidden NUL and were rejected at PRD validation; removed that fixture character only, retained the initial receipt, then reproduced the actual containment failures before changing source.
+
+After: every requirement field is rendered in one JSON record per line under explicit data markers, with quotes/backslashes/control characters and Unicode controls/formatters/line separators escaped. The 16,384-byte limit still counts raw UTF-8 titles plus texts before encoding; metadata and escaping add message bytes. Budget/codepoint/later-ID/truncation/ask-PM semantics remain. After async lookup, resume rereads revision/phase/snapshot, discards changed bindings and re-settles before any continuation write. Real-catalog regression commits a new owner spec at implementation revision 7, consumes/relaunches the coder and proves discovery revision 8 with no newly persisted obsolete coder message. Four hostile-field/consumer cases and two encoding/budget cases added; changed continuation file 38/38. All 225 bus/tasks/harness/business whole files ran sequentially with Node v24.22.1, per-file pipefail/tee and fresh /mnt/storage/scratch/tmp/XXXXXX TMPDIR: initial 2287 pass / 1 fail / 0 skip, solely the known claude-session.test.mjs:329 row-66 correction-notice flake on turn 3; unchanged whole-file rerun 10 pass / 0 fail / 0 skip. Terminal repository cases 2288/0/0; reviewer-suite author rerun 11/0/0 plus byte-identical real-catalog reproduction 1/0/0. Initial failure remains recorded, not relabeled. No other positive failure or skip. Intent/evidence/digest compatibility, deduplication and coder/reviewer list_requirements exclusion pass; protected role/tool/schema hashes unchanged. Changed-path hex-pin search has no pin, positive control finds four. One local commit authorized; no push, amend, rebase, force, stash, remote/live/model/secret/fleet/.53 action. Queue refused linked worktree, no bypass/move. Report and per-file evidence: /mnt/storage/scratch/mosaic-lead/mvp3/req-texts-fix-r2-report.md and req-texts-fix-r2-evidence/. Ready for independent exact-commit review; no R2 approval, CI, deployment or product acceptance claimed.
