docs(r3): retire Go UnknownVariant debt row by briansrls · Pull Request #1545 · gunb-ai/gunbc

briansrls · 2026-05-03T00:00:56Z

Summary

marks the Go UnknownVariant debt row retired in the R3 debt-paydown ledger
updates ROADMAP.md with the PR fix(v3): B1 Go UnknownVariant fabrication to VariantParentNotFound #820 resolution receipt
removes Go UnknownVariant from active highest-leverage retirement bundles

Why

silent-boar-29 verified the implementation already landed in PR #820: Go branch emission now returns EmitError::VariantParentNotFound and has regression coverage. The ledger still listed the row as open, so this PR records the actual state and keeps the debt-paydown queue from redispatching stale work.

R3 Debt Receipt

Debt paid — Go branch emits UnknownVariant is marked retired in docs/debt/r3-debt-paydown-ledger-2026-05-02.md; ROADMAP.md now cites PR fix(v3): B1 Go UnknownVariant fabrication to VariantParentNotFound #820 as the closure receipt. Dissolution mechanism: typed EmitError::VariantParentNotFound, no UnknownVariant fallback, missing-parent regression coverage.
Debt found + routed — none.
No debt touched — not applicable.

Docs-only PR retiring a debt row. Counts and renumbering are consistent (60→59 open, 3→4 retired; list renumbered 4-6, retirement targets renumbered).

Verdict: APPROVE — docs-only debt-ledger update marking the Go UnknownVariant row retired via PR #820. Bucket counts, retired list, highest-leverage list, and bundle recommendation all updated consistently. No code change, no invariant concerns.

Verdict: APPROVE

The Go UnknownVariant retirement is backed by existing code and regression coverage from PR #820, and the docs/ledger updates consistently move that row out of active debt. I found no concrete violations of the pinned invariants, coding, or testing guidance in this diff.

I did not run builds or tests, per instruction.

1. Story of the diff

This PR is a debt-ledger retirement, not the emitter fix itself. It takes the previously open ROADMAP row for Go branch emission fabricating UnknownVariant and marks it resolved by PR #820, explicitly saying the live behavior is now EmitError::VariantParentNotFound { variant_id } plus missing-parent regression coverage at ROADMAP.md:468. The R3 debt ledger is kept in sync: open implementation rows drop from 60 to 59, retired/stale rows rise from 3 to 4, the Go row changes from Open to Retired, and the item is removed from both the “highest-leverage” queue and the fail-closed mini-bundle at docs/debt/r3-debt-paydown-ledger-2026-05-02.md:20, :22, :73, :119, and :154.

The generated/test collateral then refreshes the derived view of src/v3/std/induction.dag: both bootstrap fixture snapshots update only numeric SourceSpan byte ranges, and the parse corpus manifest updates the induction entry hash at src/v3/compiler/tests/integration/parse_corpus_manifest.txt:43. I did not see live emitter logic, substrate schema, or hand-written Rust behavior changed in this diff.

2. Invariant categories

LAYER MODEL — Compliant. The diff touches Dag-shaped generated fixture data, but only by updating existing SourceSpan coordinates such as span: SourceSpan::new("src/v3/std/induction.dag", 12076, 12638) at src/v3/compiler/src/bootstrap_generated.rs:24915; it does not introduce a new substrate type, variant, field, or cross-pass authority.
INVARIANTS.md + modeling-discipline.md — Compliant. P5 Progress Is Dissolution is handled directly: the open debt row is struck through and resolved to a typed fail-closed receipt at ROADMAP.md:468, while the ledger changes the same item to Retired at docs/debt/r3-debt-paydown-ledger-2026-05-02.md:73. P3 Fail-Closed is also represented correctly in the retirement text: the recorded mechanism is EmitError::VariantParentNotFound { variant_id }, not a continued target-code fallback.
CODING.md — N/A. No hand-written Rust functions, helpers, APIs, error shapes, naming, or method/free-function structure changed; the Rust changes are generated numeric snapshot updates only, for example src/v3/compiler/src/bootstrap_generated_without_parse_surface.rs:24915.
TESTING.md — Compliant. This PR does not add new behavior needing a new test; it refreshes generated test/snapshot collateral instead. The parse corpus manifest records the updated src/v3/std/induction.dag digest at src/v3/compiler/tests/integration/parse_corpus_manifest.txt:43, and both bootstrap snapshot files carry matching generated span updates.
LOCKED DESIGN DECISIONS — N/A. The diff does not alter a locked design document or change a locked substrate/design commitment; it records an existing PR fix(v3): B1 Go UnknownVariant fabrication to VariantParentNotFound #820 receipt in ROADMAP/ledger prose at ROADMAP.md:468.
TRACKED vs UNTRACKED DEBT — Compliant. No new scaffold, TODO, bridge, or temporary shape is introduced. The tracked debt state moves in the right direction: counts are adjusted at docs/debt/r3-debt-paydown-ledger-2026-05-02.md:20 and :22, the retired receipt is enumerated at :107, and the item is removed from the active fail-closed bundle at :154.

3. Verdict

APPROVE

The diff consistently retires one tracked debt item and keeps the ledger/queue math aligned with that retirement. The generated snapshot and manifest changes are narrow derived-artifact refreshes, and I did not find a diff-supported invariant, testing, or coding finding.

Non-blocking — Strengths

ROADMAP.md The Go UnknownVariant row is retired with a concrete fail-closed receipt that matches the PR-head emitter behavior and regression test.
docs/debt/r3-debt-paydown-ledger-2026-05-02.md Ledger counts, row status, cleanup-only list, and dispatch bundle stay internally consistent after moving Go UnknownVariant to retired.

ROADMAP — Verified

Go UnknownVariant retirement: At PR head, Go sum-branch emission returns EmitError::VariantParentNotFound on missing variant-parent info and includes a regression test for that case.

✅ No blocking concerns.

APPROVE — Docs-only retirement of the Go UnknownVariant debt row plus mechanical bootstrap/parse-corpus snapshot refreshes. Bucket arithmetic is consistent (60→59 open, 3→4 retired, total 69 preserved), section renumbering in the ledger is internally consistent, and ROADMAP strikethrough preserves history while pointing to PR #820 as the retirement receipt. No invariant or modeling-discipline concerns in this diff.

Docs-only retirement looks consistent: ROADMAP marks the Go UnknownVariant row resolved, the R3 ledger count moves one row from open to retired, and the dispatch target list removes that already-retired work.

Findings

None. The diff only updates ROADMAP.md and docs/debt/r3-debt-paydown-ledger-2026-05-02.md to record that the Go UnknownVariant item is addressed by PR #820 (EmitError::VariantParentNotFound, regression coverage). That matches INVARIANTS.md P3 (fail-closed) as documentation of closure, not a new behavior. CODING.md / TESTING.md do not apply to these markdown edits. Bucket totals stay consistent (open −1, retired +1; still 69 classified rows).

Verdict

APPROVE — Narrow docs/ledger retirement aligned with a named receipt (PR #820); no invariant or discipline issues in the changed lines.

1. Story of the diff

This PR is a debt-ledger cleanup for the Go UnknownVariant fail-closed row, not an implementation change. ROADMAP.md:468 converts the prior open finding into a struck-through historical row and records PR #820 as the receipt: Go branch emission now fails with EmitError::VariantParentNotFound { variant_id } instead of fabricating a Go case label. The R3 debt ledger then keeps the bookkeeping consistent: open rows drop from 60 to 59 and retired/stale rows rise from 3 to 4 at docs/debt/r3-debt-paydown-ledger-2026-05-02.md:20 and :22, the specific ledger row moves from Open to Retired at :73, the stale/retired section gains the Go entry at :107, and the highest-leverage target list plus first retirement bundle remove Go UnknownVariant from active work at :119 and :154.

I treated the PR #820 implementation and tests as outside this diff; this review is only about whether this PR’s documentation and debt-accounting changes are coherent.

2. Invariant categories

LAYER MODEL — N/A. The diff is documentation/debt-ledger bookkeeping only; it does not touch Dag substrate types, implementation data models, lowering, emit code, or cross-pass carriers.
INVARIANTS.md + modeling-discipline.md — Compliant. P3 Fail-Closed / C-6 / C-9 are handled as a retirement receipt rather than hidden: ROADMAP.md:468 says the prior fabricated "UnknownVariant" path is resolved by typed EmitError::VariantParentNotFound { variant_id }, and docs/debt/r3-debt-paydown-ledger-2026-05-02.md:73 mirrors that retirement instead of leaving the row open.
CODING.md — N/A. No Rust implementation, helper shape, API surface, method/free-function choice, or error/result contract is changed in this diff.
TESTING.md — Compliant. This PR does not add tests because it does not add behavior; the retirement text explicitly records that the underlying implementation receipt included missing-parent regression coverage at ROADMAP.md:468 and docs/debt/r3-debt-paydown-ledger-2026-05-02.md:73.
LOCKED DESIGN DECISIONS — N/A. The diff does not alter a locked thesis/design decision or introduce divergence from one; it updates ROADMAP and an R3 debt ledger entry.
TRACKED vs UNTRACKED DEBT — Compliant. The change reduces tracked open debt without adding a new scaffold/TODO: the bucket counts move one item from open to retired at docs/debt/r3-debt-paydown-ledger-2026-05-02.md:20 and :22, the stale/retired list adds the explicit PR fix(v3): B1 Go UnknownVariant fabrication to VariantParentNotFound #820 receipt at :107, and active-work planning removes Go UnknownVariant from the leverage list and bundle at :119 and :154.

3. Verdict

APPROVE

The diff is internally consistent debt retirement: it updates the ROADMAP row, ledger status, aggregate counts, stale/retired section, and active-work queues in the same direction. I found no new substrate shape, implementation behavior, scaffold, or test obligation introduced by this PR.

Go UnknownVariant debt retirement: Current emitter code returns typed EmitError::VariantParentNotFound on missing Go variant-parent info and includes regression coverage for that fail-closed path.

✅ No blocking concerns for this design/docs-only retirement update.
