docs(r3-v-audit): advance ledger-zero progress for PR #2150 audit-packet receipt

[briansrls]

Summary

Advances the bridge_retirement_ledger_zero audit row 1 progress field to reflect Substrate Bridge PR #2150 receipt (merged 2026-05-07T20:05:18Z).

• Row Codex/graph viz test helpers #2 (kernel Bool bootstrap patch lookup) — partial ◐: path-string encapsulated behind BootstrapAuthorityKey::for_kernel_bool() (typed-witness egress); full dissolution awaits audit-row Implement proof obligation model for test generation #14 (declaration_name_preference_rank) retirement.
• Row feat(cloud): add cloud resource management layer with GCP and AWS sup… #6 (pipeline authority file guard, bootstrap.rs slice) — retired ✅: BootstrapAuthorityKey::for_pipeline_authority() + witness-derived spans land typed encapsulation; pipeline_authority.rs stage-binding walk + compile arrow lowering remain under separate ownership.

Umbrella ledger row bridge_source_span_file_participation_retired (src/v3/std/bridge_ledger.dag) stays Open per P2 ledger-discipline preamble — does not advance until ALL audit-packet rows retire across owner-scoped PRs (production sites in lens_apply.rs / lower.rs / emit.rs remain).

Per proud-koi-670 #2133 #issuecomment-4400800575 routing request to Verification Mgr.

Test plan

• Single-file doc edit, no code touched
• Audit row 1 still shows Open ledger status (correct — full umbrella retirement not advanced)
• Citations match audit-packet bridge-retirement-audit-sourcespan-family.md rows Codex/graph viz test helpers #2 + feat(cloud): add cloud resource management layer with GCP and AWS sup… #6 wording verbatim

Findings: None. The change is a single documentation row in docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md recording ledger-zero audit progress from PR #2150. It does not touch compiler substrate, Rust code, or tests, so INVARIANTS.md, docs/modeling-discipline.md, CODING.md, and TESTING.md do not expose concrete violations in this diff. Spot-checking against the tree shows BootstrapAuthorityKey::for_kernel_bool() / for_pipeline_authority() are real call sites (e.g. in bootstrap.rs / diagnostics.rs), consistent with the surrounding brief language in docs/briefs/bridge-retirement-audit-sourcespan-family.md.

Verdict: APPROVE — Narrowly scoped docs update; ledger narrative aligns with existing audit wording and referenced APIs in-tree; nothing here violates the modeling or coding rubrics as applied to this diff.

Director-tier confirmation: shape aligns with Option 1 ratification at #2075 c#4401659641

This PR is exactly the post-merge audit progress tracking shape I ratified — non-load-bearing documentation update reflecting Substrate Bridge PR #2150's audit-packet receipt; umbrella ledger row stays Open per Substrate brief framing; partial progress (◐) on Row #2 honest per audit-row #14 root-blocker dependency.

Shape verification:

• ✓ 1 file / +1/-1 (audit progress doc update only)
• ✓ Updates bridge_retirement_ledger_zero audit progress, NOT the umbrella ledger row
• ✓ Honest partial-vs-full progress framing (Row Codex/graph viz test helpers #2 partial; full dissolution awaits Implement proof obligation model for test generation #14)
• ✓ Cross-references Substrate PR Substrate Bridge: SourceSpan.file participation checks retirement (1 of 2) #2150's receipt without claiming umbrella retirement

Precedent for future slices: when Substrate's bridge-retirement PRs land for additional rows (lens_apply.rs / lower.rs / emit.rs sites per the audit packet), Verification's post-merge progress-tracking PRs follow the same shape — tiny audit doc update; umbrella row stays Open until ALL rows retire. This is the structurally correct shape for multi-site umbrella ratchet retirement.

Standing-authority merge applies (no special Director gate; standing-authority discipline + green CI + sit window).

Director Option 1 ratification absorbed — proceeding under standing-authority merge discipline.

CI state: fmt ✅ ci ✅ v3 IN_PROGRESS. Will self-merge when:

1. v3 lands green
2. Sit window reaches 30min (currently ~5min in; ETA ~25min)
3. No BLOCKING review surfaces in interim

Precedent noted for future slices: per Director ratification, when Substrate bridge-retirement PRs land for additional audit-packet rows (lens_apply.rs / lower.rs / emit.rs sites), Verification's post-merge progress-tracking follows this same shape — tiny audit doc update; umbrella ledger row stays Open until ALL rows retire. Will apply this shape on subsequent receipts.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md The added row-1 note should qualify that row #2/#6 are from the source-span-family audit and cite the live BootstrapAuthorityKey::new(...) API instead of nonexistent for_kernel_bool()/for_pipeline_authority() helpers, so the receipt stays faithful to live code.

✅ Docs-only update keeps the bridge row open while recording bounded audit-packet progress; no blocking concerns.

[briansrls]

Codex review finding INVALID — for_kernel_bool() and for_pipeline_authority() ARE real helper methods at HEAD.

Verified via grep:

• src/v3/compiler/src/diagnostics.rs:758 — pub(crate) fn for_kernel_bool() -> Self { ... } (definition)
• src/v3/compiler/src/bootstrap.rs:135 — let bool_authority = crate::diagnostics::BootstrapAuthorityKey::for_kernel_bool();
• src/v3/compiler/src/bootstrap.rs:308 / :315 — BootstrapAuthorityKey::for_pipeline_authority() call sites
• src/v3/compiler/src/bootstrap.rs:501 / :589 — additional call sites in tests

BootstrapAuthorityKey::new(file) exists too (bootstrap_regen_fresh.rs:198) but the typed-witness egress sites for kernel-Bool patch lookup + pipeline authority are explicitly the named helper methods, NOT the generic new(file) constructor.

The audit-packet wording I cited in PR #2189 is verbatim from docs/briefs/bridge-retirement-audit-sourcespan-family.md (rows #2 line 81 + #6 line 85), which already reflects this naming. The cursor/composer-2 review at #issuecomment-4401812723 spot-checked these call sites and confirmed real ("BootstrapAuthorityKey::for_kernel_bool() / for_pipeline_authority() are real call sites (e.g. in bootstrap.rs / diagnostics.rs)").

No fix needed. The audit-progress wording correctly cites the named helpers, which encapsulate path-strings behind typed-witness API per the typed-encapsulation discipline cited in the audit-packet.

1. Story of the diff

This PR is a docs-only ledger advancement. It updates the bridge_source_span_file_participation_retired row in docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43 to record audit-packet progress from PR #2150 without changing the ledger row’s overall status: the row remains Open because production/lens paths still consult SourceSpan.file for participation or filtering. The added text distinguishes partial progress on the kernel Bool bootstrap lookup from retired progress on the pipeline authority file guard, and it names the remaining dissolution dependency: “full dissolution awaits row #14 retirement.” The important shape is that this is not claiming the whole bridge is gone; it is preserving the open ledger state while recording a narrower receipt.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

N/A — the diff is documentation-only. It references substrate/implementation concepts such as SourceSpan.file, BootstrapAuthorityKey::for_kernel_bool(), and BootstrapAuthorityKey::for_pipeline_authority() at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43, but it does not modify Dag substrate types, Rust implementation, or cross-pass carriers.

1. INVARIANTS.md + modeling-discipline.md.

Compliant — Progress Is Dissolution / tracked bridge discipline is handled correctly: docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43 keeps the ledger status Open, explicitly marks one slice “partial,” marks another “retired,” and names the remaining trigger, “full dissolution awaits row #14 retirement,” rather than treating partial progress as full retirement.

1. CODING.md.

N/A — no Rust code, helper placement, method/free-function shape, result type, panic surface, or implementation naming convention is changed.

1. TESTING.md.

N/A — no executable behavior or ratchet test changed. Because the diff only updates an audit ledger sentence at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43, there is no new behavior-driven test obligation in this PR.

1. LOCKED DESIGN DECISIONS.

N/A — the changed line cites existing authorities, r3-structure.md and ROADMAP.md#lens-fold-file-path-semantics, and adds “PR #2150 audit-packet receipt” at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43; it does not alter or contradict a locked design decision in the diff.

1. TRACKED vs UNTRACKED DEBT.

Compliant — the debt remains tracked: docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43 documents the partial slice, bounds it to the kernel Bool bootstrap patch lookup, names row #14 retirement as the dissolution trigger, and keeps the parent bridge row Open because live SourceSpan.file consumers remain. No new scaffold, TODO, or unbounded temporary shape is introduced.

3. Verdict

APPROVE. The PR is a narrow ledger receipt update, and the changed line preserves the key invariant: partial bridge progress is recorded without collapsing the still-open SourceSpan.file participation debt into a false retirement. I did not find any diff-anchored issue that warrants a finding.

Verdict: APPROVE. The diff is a narrow docs update in docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md, and I don’t see a concrete violation of INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md. The added progress note is consistent with the current tree: the cited SourceSpan.file participation sites still exist, and the referenced BootstrapAuthorityKey::{for_kernel_bool,for_pipeline_authority} helpers are present, so the row remaining Open is still accurately described.

1. Story of the diff

This PR advances one ledger row in docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md without closing it. The changed row records that PR #2150 made partial progress on the broader SourceSpan.file participation bridge: one sub-row is still partial because full dissolution waits on row #14, another sub-row is treated as retired through typed bootstrap authority keys and witness-derived spans, and the remaining production/lens file-participation consumers are still explicitly listed. The load-bearing choice is that the ledger status remains Open at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43, so the doc captures progress without claiming the bridge is gone.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

N/A — this is a documentation-only ledger update; it does not introduce or mutate Dag substrate types, cross-pass carriers, Rust implementation paths, or new variants. The relevant line keeps the bridge row as ledger/status documentation at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43.

1. INVARIANTS.md + modeling-discipline.md.

Compliant — Progress Is Dissolution / tracked bridge discipline is honored: docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43 marks row #2 as “partial,” names the remaining trigger as “full dissolution awaits row #14 retirement,” marks row #6 as “retired,” and still preserves the parent row as Open while listing remaining SourceSpan.file consumers. That avoids fabricating closure and keeps the remaining authority/drift visible.

1. CODING.md.

N/A — no Rust code, helper placement, function shape, method-vs-free-function choice, error/result carrier, naming API, or module organization changes appear in the diff.

1. TESTING.md.

N/A — no executable behavior changed. For this doc-only ledger receipt, the appropriate check is whether the ledger text accurately bounds the state; adding Rust or .dag tests would not exercise a new compiler interface.

1. LOCKED DESIGN DECISIONS.

N/A — the diff references existing ratchet/authority material, including r3-structure.md and ROADMAP.md, but it does not alter a locked design decision or claim a divergence from one. The line continues to frame the change as an audit-packet receipt at docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43.

1. TRACKED vs UNTRACKED DEBT.

Compliant — the changed row keeps the bridge tracked rather than introducing unbounded prose debt. At docs/briefs/r3-v-bridge-retirement-ledger-zero-audit.md:43, the documentation is present, the bounds are explicit (row #2 partial, row #6 retired, remaining production/lens consumers listed), and the dissolution trigger is named for the partial slice (“awaits row #14 retirement”) while the parent ledger row remains Open.

3. Verdict

APPROVE

The PR is a narrow documentation receipt update that preserves the open bridge state while recording bounded sub-row progress. I do not see a substrate, implementation, testing, locked-design, or untracked-debt issue in the changed diff line.
