Loomworks — Phase 57 CR amendment handoff

Version. 0.1 Date. 2026-05-12 Author. Marvin Percival (DUNIN7 Operator) with Claude.ai. Purpose. Brief a fresh Claude.ai chat to draft phase-57-cr-marketing-engagement-creation-v0_2.md — the Phase 57 CR amendment absorbing the OL signin email gate fix per the halt-surface note. Self-sufficient — the drafter does not need to re-read the scoping conversation. Companion to loomworks-phase-57-cr-amendment-scoping-note-v0_1.md, which settles all amendment construction decisions; this handoff transposes those decisions into drafting instructions.

1. What this is

Phase 57 build halted at Step 2 entry on 2026-05-12 per phase-57-halt-surface-2026-05-12-v0_1.md. The Operator Layer signin form's empty-email guard contradicts the engine's WebAuthn discoverable-credential identity contract and contradicts a standing DUNIN7 principle (email must not be used for identity). The fix is small and OL-side only; engine substrate is correct and untouched.

The amendment scoping note loomworks-phase-57-cr-amendment-scoping-note-v0_1.md settles all ten open items the halt-surface §5 named. The CR-amendment drafting chat consumes those decisions; it does not relitigate them. The drafter produces a single output: phase-57-cr-marketing-engagement-creation-v0_2.md.

CR v0.1 stays archived alongside as superseded. The amendment is a v0.1 → v0.2 progression at the CR layer, narrower in shape than Phase 49's v0.1 → v0.2 (pre-kickoff tightening) and Phase 49's v0.1 → v0.2 → v0.3 (mid-build Step 4 amendment absorption) but in the same family of CR-version progressions.

The CR amendment target filename: phase-57-cr-marketing-engagement-creation-v0_2.md. The CR's structural template: phase-57-cr-marketing-engagement-creation-v0_1.md (currently archived at engine repo docs/phase-crs/ on the build branch). Preserve the v0.1 section order and headers; insert the new Sub-arc 4 sections; amend the affected §s in place; add a brief change-record note recording the amendment shape.

2. Substrate baseline at amendment-drafting time

The CR drafter confirms the following before drafting work begins. The baseline state has shifted since Phase 57 CR v0.1 was drafted — Step 0 and Step 1 have already executed; the build branch carries those changes; the halt happened at Step 2 entry.

Engine repo DUNIN7/loomworks-engine:

• Branch: phase-57-marketing-engagement-creation at a00f4a3.
• Tests: 2,280 always-run + 32 skipped (1 always-run + 2 calibration-gated added at Step 1).
• Alembic head: 0064 unchanged.
• Working tree: clean.
• Halt-surface note: filed at docs/phase-impl-notes/phase-57-halt-surface-2026-05-12-v0_1.md on the branch (commit message: Phase 57 halt-surface: OL signin email gate contradicts engine identity contract).
• Step 0 findings: present on branch at docs/phase-impl-notes/phase-57-step-0-findings-v0_1.md.
• Step 1 substrate: present at prompts/intent_instructions/create_engagement/additional_assertions.md.

Operator Layer repo DUNIN7/loomworks:

• Branch: phase-57-marketing-engagement-creation at 2cc0ebc (= Phase 56 commit; no Phase 57 changes yet — the amendment changes this).
• Tests: 149 vitest passed; 11 prerendered routes; lint/tsc/build clean.
• Working tree: clean.

Local stack (per halt-surface §6):

• Engine API up on :8000; /healthz returns 200; CORS resolved (LOOMWORKS_ENV=development in local .env).
• OL dev server up on :3001; banner revision present at ChatView.tsx:254.
• Marvin's Person row exists in the dev DB; passkey credential registered.

No mid-build commits to revert. Phase 57 Step 1 substrate is correct and stays. The amendment adds work; it does not undo work.

3. Reading order before drafting

The CR amendment drafter reads in this order:

1. This handoff.
2. loomworks-phase-57-cr-amendment-scoping-note-v0_1.md (project knowledge) — authoritative for amendment scope; all ten P57-Ax items settled.
3. phase-57-halt-surface-2026-05-12-v0_1.md (project knowledge) — the halt-surface that opened this amendment cycle; CC's three findings against the live engine + OL source; the standing DUNIN7 principle named for the first-time-in-a-Loomworks-document record.
4. phase-57-cr-marketing-engagement-creation-v0_1.md (project knowledge; also archived at engine repo docs/phase-crs/) — the CR being amended. Preserve v0.1's section structure; the amendment inserts and edits in place rather than reorganizing.
5. loomworks-phase-57-scoping-note-v0_2.md (project knowledge) — Phase 57's authoritative scoping note going into the build. The amendment scoping note extends this, does not supersede it.
6. loomworks-phase-57-cr-drafting-handoff-v0_1.md (project knowledge) — original CR drafting handoff. The §10 CR target shape is the structural template the amendment preserves.
7. phase-49-cr-amendment-v0_2-v0_1.md (engine repo docs/phase-crs/) — Phase 49's pre-kickoff CR amendment (T1/T2/T3 tightening); closest precedent for the shape of a CR-version bump.
8. current-status-manifest-v0_41.md (project knowledge) — substrate baseline; standing principles (especially §2 substrate-friction-discipline-pattern, reserved-slot-as-halt-condition-pre-commitment reformulation, refspec convention).

4. What's settled — ten P57-Ax items

All decisions closed at scoping. The drafter consumes them; does not relitigate.

| Item | Setting | |------|---------| | P57-A1 | Remove empty-email guard; omit email from POST body when empty; update field surface text to indicate optionality. Email field stays present (narrows allowCredentials as a passkey hint when supplied); discoverable-credential path is the normal path. | | P57-A2 | One new vitest. Exercises empty-email submission → no emailEmptyError → POST body omits email → mock returns WebAuthn challenge → form transitions to passkey step. | | P57-A3 | Narrow audit limited to the signin form only. Sign-up, claim-flow, account-recovery, and other identity-adjacent OL surfaces deliberately out of amendment scope. OL surface-vs-contract audit queued as Phase 58+ candidate. | | P57-A4 | Public marketing form out of scope. Phase 51 form handles email as contact metadata; principle distinguishes identity from contact. CR-amendment-drafting verifies HOLDS; expected verdict HOLDS. | | P57-A5 | CR version phase-57-cr-marketing-engagement-creation-v0_2.md. v0.1 preserved alongside as superseded; both archived at engine repo docs/phase-crs/. | | P57-A6 | New Sub-arc 4: OL surface alignment with engine identity contract. Separate sub-arc keeps engine / OL boundary visible. | | P57-A7 | Test count update: OL vitest 149 → 150. Engine 2,280 always-run + 32 skipped unchanged. Alembic 0064 unchanged. | | P57-A8 | Two CR §12 gate updates. Gate 5 amended to include Sub-arc 4 readiness. New Gate 5b: OL signin surface accepts empty email and proceeds to passkey path. Total gates 17 → 18. | | P57-A9 | Three methodology candidates carry to v0.21 / v0.42. Candidate A (engine-correct-surface-drifted), Candidate B (standing-principle-not-named-in-source-of-truth-documents-allows-contradicting-surface-to-ship), Candidate C new at amendment scoping (substrate-friction-discipline-pattern-second-build-mode-firing). | | P57-A10 | One reserved buffer slot consumed. One remains. First consumed reserved slot since Phase 49 Step 4; eight consecutive zero-consumption phases ended at this amendment. |

5. Sub-arc 4 decomposition

Three components. All OL-side. CR §-numbering follows v0.1 precedent; amendment inserts as a new sub-section adjacent to the existing Sub-arc 1 / 2 / 3 sections (do not renumber existing sub-arcs).

4a. Signin form gate removal.

• File. IdentifierStep.tsx (CR drafter verifies exact path against current branch state; halt-surface §2 Finding 2 cites IdentifierStep.tsx:31).
• Change. Remove the empty-email guard:

``` if (!email.trim()) { setLocalError(SIGNIN.emailEmptyError); return; } ``` Replace with: proceed to submission unconditionally (no email-required gate at the client).

• Constant cleanup. SIGNIN.emailEmptyError likely becomes orphaned. CR drafter verifies the constant's location and other call-sites at amendment-drafting time. If no other call-sites: delete the constant. If orphaned but otherwise harmless: leave with a one-line comment noting Phase 57 amendment removed the sole caller.

4b. POST body construction.

• File. signin-flow.ts (CR drafter verifies exact path; halt-surface §2 Finding 2 cites signin-flow.ts:42).
• Change. POST body to /auth/login/begin currently constructed as { email: email.trim() }. Change to omit the email field when empty — idiomatically, build the body conditionally:

```ts const body = email.trim() ? { email: email.trim() } : {}; ``` (Exact TypeScript idiom the drafter selects; engine accepts {} cleanly per halt-surface Finding 1.)

4c. Field surface text — optionality indication.

• File. Likely IdentifierStep.tsx (label) plus any helper-text component the form composes (CR drafter verifies). The strings probably live in a strings constant such as SIGNIN.identifierLabel / SIGNIN.identifierPlaceholder / SIGNIN.identifierHelper (exact constants verified at drafting).
• Change. Update copy to indicate the field is optional. Recommended shape (plain-terms-discipline per Phase 56's voice principles):
• Label: Email (unchanged) or Email (optional).
• Placeholder: Email (optional) if not already.
• Helper text near the field: short, plain. Example: "Leave blank to sign in with any passkey." Drafter selects the final copy at amendment-drafting time within plain-terms-discipline.
• No methodology vocabulary. Plain-terms applies. Do not write "discoverable credential," "WebAuthn," or "Companion" in the helper copy.

4d. Vitest.

• File. Add to existing OL test surface for signin. CR drafter verifies the path and existing test file pattern against branch state (likely tests/components/signin/ or analogous; existing 149 vitest provide the convention).
• Behavior pinned. Empty email + submit → localError does not get set to emailEmptyError → POST body to /auth/login/begin is {} (or omits the email field equivalently) → mocked /auth/login/begin returns a WebAuthn challenge → form transitions to the passkey step. The test mocks the engine boundary at the fetch / API layer; does not exercise live engine.
• Test name shape. Suggested: something like submits empty email to discoverable-credential path or proceeds to passkey step without requiring email input. Drafter selects within existing test-naming conventions on the branch.

6. Revised build steps

The CR §10 build steps list updates as follows. v0.1 ordering preserved; Step 2a inserted; Step 2 renamed Step 2b for clarity; subsequent steps unchanged.

• Step 0. Pre-flight + CR archival + build branch. DONE pre-halt. CR archival path updates from v0_1 to v0_2 at amendment-execution time.
• Step 1. Field 6 prompt authoring (Sub-arc 1). DONE pre-halt at engine a00f4a3.
• Step 2a — NEW. OL signin alignment (Sub-arc 4). Components 4a + 4b + 4c + 4d. Run lint / tsc / build / test on OL after the change; expect OL vitest count 150 green. Halt threshold: any of the four components surfaces unexpected drift from CR specification, or test count diverges beyond ±1 from 150. Checkpoint A extends to cover Step 2a. Operator confirms Sub-arc 4 fix before Step 2b proceeds.
• Step 2b — was Step 2. Live usage event (Sub-arc 2). Marvin retries signin via /operator/create-engagement; passkey discoverable-credential flow completes; marketing engagement creation conversation proceeds. Halt threshold: signin still fails (would indicate a deeper engine-side issue the diagnostic missed; halt and re-diagnose).
• Step 3. Calibration capture (Sub-arc 3a/3b). Unchanged.
• Step 4. Observation capture (Sub-arc 3c). Unchanged. The implementation notes document captures the amendment cycle, the second build-mode firing of substrate-friction-discipline-pattern, and any Step 2a refinement observations alongside the original Sub-arc 3c content.
• Step 5. Close. Unchanged. Refined close protocol with explicit refspecs; tag phase-57-marketing-engagement-creation on both repos (annotated); P57-D7 Option A retroactive cleanup.
• Reserved slot accounting. One of two original reserved slots consumed by Sub-arc 4; one remains available if Steps 2b–5 surface a second halt-and-amend cycle (not anticipated).

7. CR target shape

7.1 Document-level changes

Header section of v0.2:

• Version. 0.2.
• Date. Amendment-drafting date.
• Status. Amendment cycle 1; supersedes v0.1.
• Amendment record (brief, near the header). One short paragraph naming what changed in v0.2: "Amendment cycle 1 absorbed per phase-57-halt-surface-2026-05-12-v0_1.md and loomworks-phase-57-cr-amendment-scoping-note-v0_1.md. Sub-arc 4 (OL surface alignment with engine identity contract) added; Step 2a inserted; Step 2 renamed Step 2b. OL vitest count 150 (was 149). Gate 5 amended; Gate 5b new. One reserved buffer slot consumed (one remains). Engine substrate unchanged."

7.2 Section-level changes

Preserve v0.1's section order and numbering. The amendment edits in place and inserts new sub-sections; it does not reorganize.

• §1 Executive summary. Append one sentence noting amendment cycle 1 absorbed Sub-arc 4.
• §2 Background. Append one paragraph noting the halt-surface trajectory (Position 1 → 2 → 3 per the amendment scoping note's How we got here).
• §3 Construction decisions. Append the ten P57-Ax decisions per §4 of this handoff as a new subsection §3.A (so as not to renumber the v0.1 P57-D items).
• §4 Trajectory worth preserving. Append the amendment trajectory (Position 1 → 4 per amendment scoping note) and the three new methodology candidates (A + B + C) per P57-A9.
• §5 Substrate surfaces shipped. Append a new Sub-arc 4 sub-section per §5 of this handoff. Cite file paths verbatim where settled (IdentifierStep.tsx, signin-flow.ts, and any strings file the drafter identifies at verification time). Note that engine surfaces are unchanged.
• §6 What Phase 57 does NOT deliver. Append two items: broader OL surface-vs-contract audit (queued as Phase 58+ per P57-A3); what-dunin7-is-building v0.21 absorption (out of scope per halt-surface §5 settled item 5).
• §7 Test strategy. Update OL vitest count from 149 to 150; specify the new test's behavior per §5 component 4d. Engine test counts unchanged.
• §8 Backwards-compatibility. Append one paragraph: existing 149 OL vitest stay green; the new vitest pins the corrected behavior; engine substrate untouched, so all engine backwards-compat carries.
• §9 FORAY hooks. Unchanged. The amendment touches no Memory event, no _ANCHOR_PRIORITY entry, no engine endpoint.
• §10 Build steps. Replace with the revised list per §6 of this handoff. Renaming and insertion only; numbering preserves v0.1's intent.
• §11 Halt conditions. Append Step 2a halt conditions per §6 of this handoff.
• §12 Acceptance gates. Amend Gate 5; insert new Gate 5b; renumber subsequent gates with +1 offset. Total 18 gates per P57-A8.
• §13 Post-CR state. Unchanged.
• §14 Carry-forward. Append the three methodology candidates per P57-A9 and the new queued direction (OL surface-vs-contract audit) per P57-A3.
• §15 Kickoff prompt. Update CR path reference from v0_1 to v0_2; update OL vitest count from 149 to 150; update reserved-slot language to reflect one consumed / one remaining; reference Step 2a as the resumption point (CC's first build action under v0.2 is Step 2a).
• §16 Test count predictions. Update OL vitest from 149 to 150; engine + Alembic head unchanged.
• §17 Refined close protocol script. Unchanged. The close protocol commands are step-5 work; they do not depend on Sub-arc 4 specifics.

7.3 Reserved-slot buffer language (per Phase 49/50/51/52/53/54/55/56 precedent)

The amended CR §10 carries the reserved-slot convention. With one slot now consumed (the Sub-arc 4 budget), CR §10 reads the remaining slot as (reserved — buffer for any further mid-build amendment arising from steps 2b–5). Reserved-not-skipped principle preserved; the slot's value is its presence, not its consumption.

8. CR-amendment-drafting-time verifications

Step 0 absorbed engine-side substrate verifications cleanly at Phase 57 v0.1. The halt-surface diagnostic established OL-side findings against the live phase-57-marketing-engagement-creation branch at OL commit 2cc0ebc. The remaining drafting-time verifications focus on exact strings, exact paths, exact constant locations, and existing test conventions.

The CR amendment drafter verifies the following at draft time (read live; substitute exact strings into CR §5 / §7 sections):

1. IdentifierStep.tsx exact path and current line numbers. Halt-surface cites IdentifierStep.tsx:31; verify the file's location in the OL repo's tree (likely under src/components/signin/ or analogous).
2. SIGNIN.emailEmptyError constant — location and all call-sites. Determine the strings file; determine whether removing the sole caller orphans the constant. Plan: delete if orphaned, leave with a comment if any other caller remains.
3. signin-flow.ts exact path and POST body construction at line 42. Verify the current shape; specify the new idiomatic conditional body in TypeScript.
4. Field surface text constants. SIGNIN.identifierLabel, SIGNIN.identifierPlaceholder, SIGNIN.identifierHelper (or whatever the exact constants are). Specify new copy values in the CR §5 sub-section.
5. Existing vitest convention for signin tests. Read the existing vitest under whatever signin-related test folder exists; the new vitest matches that file structure and naming convention.
6. /auth/login/begin POST body absent-email engine behavior. Halt-surface Finding 1 establishes this; re-read the engine LoginBeginRequest schema and the route handler to triple-confirm. Expected verdict: engine accepts email: None cleanly via Pydantic optional default; absent field and null field are equivalent.
7. Phase 51 marketing form signature. Per P57-A4: verify the public marketing form's submission handler keys off the form-event Memory write, not an email-based auth lookup. Expected verdict: HOLDS (the form is contact intake, not identity).
8. Existing OL vitest count baseline. Halt-surface §6 cites 149 OL vitest. Re-confirm on the OL repo's phase-57-marketing-engagement-creation branch at 2cc0ebc. Expected: 149.

For each verification, the CR amendment drafter records exact strings inline in the CR sub-sections. If any verification surfaces unexpected divergence (e.g., the strings file is structured differently than expected, or LoginBeginRequest has shifted shape since halt-surface diagnostic time), the drafter halts and surfaces rather than writing assumptions into the CR.

9. Halt conditions at amendment-drafting time

The drafter halts and surfaces (rather than drafting around the issue) if any of the following arises:

• Verification surface mismatch. Any of the eight verifications above returns BROKEN / SCHEMA-MISMATCH / NOT-PRESENT.
• Phase 51 marketing form contradicts P57-A4. If the marketing form does key off email as identity in some path the halt-surface §5 didn't anticipate, amendment scope must re-open — that signals a broader audit is necessary before Step 2b can succeed.
• IdentifierStep.tsx or signin-flow.ts already changed since halt-surface diagnostic time. Possible if someone (CC, the Operator) edited the OL branch between halt-surface filing and amendment drafting. Drafter re-reads halt-surface findings against current branch state; if findings still HOLD, proceed; if findings have shifted, surface to Operator.
• CR v0.1 structural shape doesn't admit clean amendment. If preserving v0.1 sections and inserting new sub-sections produces ambiguity (e.g., the new Sub-arc 4 sub-section would conflict with v0.1 §5's existing structure), drafter halts and asks whether v0.2 should restructure §5 instead of inserting. Default: insert without restructuring.

10. Methodology observations to carry forward

Two from the halt-surface, one new at this scoping arc:

1. Candidate A — engine-correct-surface-drifted. Single-instance evidence at Phase 57 halt-surface. Carries to v0.42 manifest absorption and v0.21 methodology consolidation.
2. Candidate B — standing-principle-not-named-in-source-of-truth-documents-allows-contradicting-surface-to-ship. Single-instance evidence. Carries with remediation: name email-not-identity in what-dunin7-is-building at v0.21.
3. Candidate C (new at amendment scoping) — substrate-friction-discipline-pattern-second-build-mode-firing. Two-instance evidence (Phase 49 Step 4 first; Phase 57 Step 2 second). The two instances are usefully different in shape — Phase 49 was engine-side architectural friction at impl time; Phase 57 is OL-side surface-vs-contract drift at first usage. The pattern shape generalizes. Reaches the two-instance promotion threshold per manifest v0.39 §2 / v0.40 §2 precedents.

The CR amendment drafter records all three in §4 Trajectory worth preserving (not in §3 Construction decisions, which records architectural choices, not methodology observations).

11. Reserved-slot pattern continuation

Phase 50 through Phase 56 each left all reserved slots unconsumed (seven consecutive zero-consumption phases per manifest v0.41 §1). Phase 57 was projected to extend the pattern to eight, but the substrate-friction-discipline-pattern fired at Step 2 entry and consumed one slot. The pattern's design intent fires correctly: slots exist to absorb mid-build amendment without derailing the phase. The eighth-consecutive observation is now superseded; the new observation is seven-and-then-one-consumed-by-design. Methodology candidate C captures this.

The amended CR §10 carries the remaining reserved slot with the standard reserved-not-skipped language.

12. CR amendment kickoff prompt for the drafting chat

Draft phase-57-cr-marketing-engagement-creation-v0_2.md — the
amendment to Phase 57's CR that absorbs the OL signin email gate fix
per the halt-surface trajectory.

Read in this order:
1. loomworks-phase-57-cr-amendment-handoff-v0_1.md (this handoff)
2. loomworks-phase-57-cr-amendment-scoping-note-v0_1.md (project
   knowledge — settles all ten P57-Ax items)
3. phase-57-halt-surface-2026-05-12-v0_1.md (project knowledge —
   the halt that opened this amendment cycle; CC's three findings;
   the standing DUNIN7 principle named)
4. phase-57-cr-marketing-engagement-creation-v0_1.md (project
   knowledge; also at engine repo docs/phase-crs/ on the build
   branch) — the CR being amended; preserve its section structure
5. loomworks-phase-57-scoping-note-v0_2.md (project knowledge —
   Phase 57's authoritative scope going in)
6. loomworks-phase-57-cr-drafting-handoff-v0_1.md (project
   knowledge — original CR drafting handoff)
7. phase-49-cr-amendment-v0_2-v0_1.md (engine repo docs/phase-crs/
   — closest precedent for CR-version-bump shape)
8. current-status-manifest-v0_41.md (project knowledge — substrate
   baseline; named principles especially §2 substrate-friction-
   discipline-pattern and refspec convention)

What this amendment adds:
- New Sub-arc 4: OL surface alignment with engine identity contract
- New Step 2a inserted before the paused Step 2 (now Step 2b)
- One new OL vitest exercising the empty-email discoverable-
  credential path (OL count 149 → 150)
- Surface-text updates indicating email-field optionality
- Updated CR §12 acceptance gates: amend Gate 5; insert new Gate 5b;
  renumber subsequent gates with +1 offset (total 17 → 18)
- Three methodology candidates A + B + C carry forward
- One queued direction added (OL surface-vs-contract audit, Phase 58+)
- One of two reserved buffer slots consumed; one remains

All ten P57-Ax items settled per the handoff §4. Substrate baseline
per handoff §2. Reading order per handoff §3. CR-amendment-drafting-
time verifications per handoff §8 (eight items; halt-and-surface
discipline if any return divergence).

Drafting discipline:
- Preserve CR v0.1's section order and numbering; insert sub-sections
  rather than reorganizing
- Add header amendment record paragraph near the top
- Engine substrate is correct and untouched; the amendment is OL-only
  plus methodology carry-forwards
- Plain-terms-discipline on any surface-text copy specified in §5
- No methodology vocabulary in helper text the user will see
- Halt and surface if any verification returns BROKEN or SCHEMA-
  MISMATCH; do not draft around uncertainty

Halt and surface to the Operator rather than draft-and-hope if any
of the §9 halt-and-escalate signals arise.

Begin by reading this handoff in full, then the amendment scoping
note, then the halt-surface note. Then read CR v0.1 in full. Plan
the v0.2 amendment shape (which sub-sections insert where, which §s
amend in place) before drafting prose. Confirm the plan with the
Operator before drafting if any uncertainty arises about preserving
v0.1's structural integrity through the amendment.

The target output: a single file at
phase-57-cr-marketing-engagement-creation-v0_2.md. v0.1 stays
archived alongside as superseded.

13. After the CR amendment is drafted

The receiving chat hands the Operator a downloadable phase-57-cr-marketing-engagement-creation-v0_2.md. The current chat's role (and the amendment scoping note's role) ends with this handoff document.

Operator workflow from there (mirrors the standard CR-amendment cadence):

1. Download v0.2 from the receiving chat.
2. Add to project knowledge alongside v0.1 (replaces nothing; both archived).
3. Open a CC session on DUNIN7-M4 (the build branch is already checked out at engine a00f4a3 and OL 2cc0ebc).
4. Paste the CR §15 amended kickoff prompt referencing v0.2 as the active CR.
5. CC archives v0.2 at engine repo docs/phase-crs/phase-57-cr-marketing-engagement-creation-v0_2.md (preserves v0.1 alongside).
6. CC runs the §8 CR-amendment-drafting-time verifications as a pre-Step-2a inspection.
7. CC implements Step 2a per the amended CR §5 / §10.
8. Checkpoint A extends — Operator confirms Sub-arc 4 fix before Step 2b proceeds.
9. CC ensures the local stack is current (OL dev server picks up the new code); Marvin retries signin and proceeds with the marketing engagement creation conversation.
10. Steps 3, 4, 5 execute per the amended CR (largely unchanged from v0.1).
11. Phase 57 close lands tag phase-57-marketing-engagement-creation on both repos per the refined close protocol; P57-D7 Option A retroactive cleanup runs.
12. Implementation notes capture the amendment cycle alongside the Sub-arc 3c content.
13. Phase 58 scoping opens with the new queued direction (OL surface-vs-contract audit) plus all standing carry-forwards.
