Manager brief Lane 2 gate listed only R2-Grounding-Rust + R2-Grounding-Python
while calling it the "Shape A 3-target grounding precondition." Worker brief
already correctly required all three (Rust + Python + Go). Add Go to manager
gate to match — single-authority discipline per INVARIANTS §P2.

Net-position summary listed "3 narrow slices landed (#1014/#1171/#1183/#1192)"
which read as a 3-vs-4 count mismatch. #1171 is the outstanding/suspended
bridge (#bridge_include_str_side_channels_retired open), not a landed slice.
Restate as 2 landed (canonical lens / lower-helper) + 1 outstanding (#1171)
+ 1 R3-deferred + 1 retired, totaling 5 — and reference closure-ledger PR
#1283 which now tracks the include_str row separately.

Manager brief promoted T-FormalGrounding-Verification to a third lane while
the structural authority docs/r3-structure.md L108 names exactly "2 lanes + 1
ledger gate" for Verification scope. That created parallel scope authority
violating INVARIANTS §P2.

Resolved by deferring to r3-structure.md authority: TC1/TC2/TC3 bundle is now
an absorbed cross-cutting responsibility (audit cadence + strict-fire tracking
folded into manager cadence), matching r3-pb-t-fixedpoint-worker.md L181
"ownership moves" wording. TC3 substrate-introduction worker brief, when its
prerequisites land, joins the existing 2-lane scope as a substrate-introduction
sub-task — not a new lane row.

If Director ratifies a third lane in r3-structure.md itself, this brief
updates accordingly; until then 2-lane scope is the authority.

Lane 1 brief had a dissolution-trigger note claiming L5 cross-target corpus
could absorb per-target L4 receipts. That conflates two categorically
different claims per THESIS.md L179-180: L4 compares emit-target output vs
.dag evaluation (per-target), L5 compares Rust/Python/Go behavior
cross-target. L5 passing does not entail any target matching .dag eval, so
L5 cannot subsume L4.

Replace with honest stability invariant matching upstream PR-D pattern, plus
explicit note that L4 has no current structural dissolution trigger (per
codex BLOCKING f5f63c7: NOT a Lens<C> instance, runtime-corpus by design).

TC bundle brief was reframed as absorbed responsibility (not a lane) but
retained "this lane" wording in five places. Replace with "this bundle"
throughout to match the locked 2-lane framing per r3-structure.md L108.

Editorial fix per cursor reviewer optional finding.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Lane 1 brief had:
- Slice 3 narrowing L7 to "at least one named law" (weakened the closure bar
  vs r3-structure.md L54 which requires every algebra × every applicable law).
- Single made-up gate name verification_l4_l7_direct_per_target_equivalence_landed
  parallel to the authoritative l4_emit_eval_match + l7_algebraic_laws_witnessed
  pair (single-authority drift per INVARIANTS §P2).

Lane 2 brief similarly used made-up verification_l5_cross_target_consistency_landed
parallel to authoritative l5_cross_target_consistency.

Manager brief acceptance section restated to cite both authority gates for
Lane 1 + L5 authority gate for Lane 2; explicit "partial-coverage early
slices do NOT close the lane" framing.

Slice 3 in Lane 1 now explicitly marked as coverage-seed only with closure
gate referring to full r3-structure.md authority.

TC3 status table named only substrate-introduction prerequisites under
"Strict-fire gate" while §Acceptance separately required T-FixedPoint
completion for strict-fire. Two competing gate descriptions for one claim
violated single-authority discipline.

Restate as a single two-stage gate:
  (a) substrate-introduction prereqs land tc3_strong_normalization_substrate_introduced
  (b) T-FixedPoint completion fires the full theorem witness

Both stages required; no fire-before-(b) path exists. Stage names match
§Acceptance authority below.

Watching for first content push. Per #1276 c#4356712454 cool-crab-614 dispatch, expecting: (1) r3-verification-manager.md scope 2→3 lanes (T-Free-Consequences as Lane 3; TC bundle stays absorbed cross-cutting); (2) NEW r3-v-free-consequences-worker.md (10-gate suite verbatim from r3-structure.md:100 — note Acceptance §:100 names the gate cost_structurally_derived per #1341 BLOCKING fix, not cost_proportional); (3) minor edit to r3-v-formal-grounding-tc-bundle.md. Single bundled PR at ~half-day. Reflection-aware modifier set is now 4 (TC1 η + TC2 strategy-order + TC3 evaluation-step + shape-report) per cool-crab-614's #1324 producer-first reframe research. Ping on draft → ready transition. — sent from zesty-bear-812

Closing as no-diff against main

PR #1342 was auto-opened from session-dashboard but the branch's only delta vs main is a WIP: R3 Verification commit (55566b1) that re-adds docs/briefs/r3-v-reflected-dag-structural-assertion-analysis.md — a file that already landed on main via PR #1324. Net diff is 0 files.

This is not a shortcut-rejected → revert situation (per feedback_redirect_noop_prs.md discipline); it's a session-tracking branch that merges from main repeatedly and incidentally tracked work already on main via a sibling worker branch. Closing without redirection because there's no real-work redirect target — the work landed via the natural cool-crab-614 path.

Routing note + dispatching the rename

This PR is the no-diff dashboard auto-PR (closed earlier). The real Lane 3 expansion work is PR #1339 (cool-crab-614 — title docs(r3): Lane 3 expansion — T-Free-Consequences-Demonstration brief authoring). Already manager-approved at #1339 c#4356784087.

Real BLOCKING finding from your comment — verified against PR #1341 diff: gate name is cross_target_optimization_cost_proportional → cross_target_optimization_cost_structurally_derived. PR #1339's worker brief + manager brief acceptance section enumerate the OLD name. Will land stale if it merges before #1341.

Dispatching cool-crab-614 to push a one-line fix-commit on PR #1339 branch renaming the gate in:

  • docs/briefs/r3-v-free-consequences-worker.md §"10-Gate TestClaim Suite" item 10
  • docs/briefs/r3-verification-manager.md §"Acceptance" Lane 3 row gate enumeration
  • (docs/briefs/r3-v-free-consequences-worker.md §"Memoization Framing" — actually no, that section anchors auto_memoization gates, not cost; only the 10-gate enumeration needs change)

Will reply when fix-commit lands. Standing by on Director's expected merge-order between #1339 and #1341.
