Summary

First per-collision cleanup from the B-0451 sweep (12 duplicate-ID groups surfaced by tools/bg/audit-duplicate-row-ids.ts in #3056).

The collision

File Filed Scope
B-0068.1-forge-cli-ollama-research-slice-aaron-2026-05-10.md 2026-05-10 (#2430) Forge CLI + Ollama harness integration research slice
B-0068.1-forge-cli-ollama-research-xs-riven-2026-05-11.md 2026-05-11 (#2650) Forge CLI + Ollama bridge research pass (WebSearch + capability matrix, XS)

Resolution

Per the per-collision resolution rule (keep the row with external references):

  • The B-0068 parent row's body describes Riven's scope ("B-0068.1 (XS, P2, root): Forge CLI + Ollama bridge research (WebSearch + matrix). Unblocks B-0068.3.")
  • Sibling rows B-0068.2 and B-0068.3 reference "B-0068.1" in depends_on / composes_with — semantically referring to Riven's atomic XS series
  • Aaron's row has no external references (verified via grep)

→ Keep Riven's row at B-0068.1; renumber Aaron's to next-free B-0068.4 with renumbered_from: B-0068.1 + reason recorded.

This bends "first-merged-wins" in favor of the external-references rule, matching #3053's precedent.

Empirical effect

Against pre-#3056 origin/main:

Signal Before After
Duplicate-ID groups 12 11

Once #3056 (the audit tool) merges, future Otto can verify via bun tools/bg/audit-duplicate-row-ids.ts.

Test plan

  • git mv preserves history
  • Inline duplicate-ID audit on the branch reports 11 (down from 12)
  • bun tools/backlog/generate-index.ts regenerated docs/BACKLOG.md cleanly
  • Worktree-isolated build (/tmp/zeta-b0068-fix)

…ed row to B-0068.4

First per-collision cleanup from the B-0451 sweep (12 duplicate-ID
groups surfaced by `tools/bg/audit-duplicate-row-ids.ts` in PR #3056).

The two B-0068.1 rows:

- `B-0068.1-forge-cli-ollama-research-slice-aaron-2026-05-10.md`
  — filed first (2026-05-10, PR #2430); scope: "Forge CLI + Ollama
  harness integration research slice"
- `B-0068.1-forge-cli-ollama-research-xs-riven-2026-05-11.md`
  — filed second (2026-05-11, PR #2650); scope: "Forge CLI + Ollama
  bridge research pass (WebSearch + capability matrix, XS)"

Per the per-collision resolution rule (keep the row with external
references):

- The B-0068 parent row's body description ("B-0068.1 (XS, P2, root):
  Forge CLI + Ollama bridge research (WebSearch + matrix). Unblocks
  B-0068.3.") describes RIVEN'S scope.
- Sibling rows `B-0068.2` and `B-0068.3` reference "B-0068.1" in their
  depends_on / composes_with — semantically referring to Riven's
  decomposition (parallel atomic XS series).
- Aaron's row has NO external references (verified via grep).

→ Keep Riven's row at B-0068.1; renumber Aaron's to next-free
B-0068.4 with `renumbered_from: B-0068.1` + reason recorded.

This bends the "first-merged-wins" rule in favor of the
external-references rule, matching PR #3053's B-0444 resolution
precedent (keep the more-referenced row, even when later-filed).

Empirical effect (against pre-PR-#3056 origin/main):

  Duplicate-ID groups: 12 → 11

Once PR #3056 (the audit tool) merges, future Otto can verify via
`bun tools/bg/audit-duplicate-row-ids.ts`.

Records: PR #3049 (Lior 429 fix) merged. PR #3056 (audit tool +
B-0451) still wait-ci. Speculative pickup: started B-0451 per-collision
cleanup with the simplest collision (B-0068.1 within-priority pair).
Renumbered Aaron's row to B-0068.4; Riven's keeps original ID due to
external references. Procedure demonstrated for remaining 11 groups.

Pull request overview

Resolves a duplicate backlog-row ID collision by renumbering the Aaron-authored B-0068.1 row to B-0068.4, keeping the externally-referenced B-0068.1 row intact, and updating the generated backlog index accordingly.

Changes:

  • Renumbered the per-row file frontmatter from id: B-0068.1 to id: B-0068.4, recording renumbered_from / renumbered_reason and updating last_updated.
  • Updated the row’s H1 header to reflect the new ID and renumber provenance.
  • Regenerated docs/BACKLOG.md to replace the old B-0068.1 entry with B-0068.4.

  • The row title still says "B-0068 child 1" even though this row is now B-0068.4 and B-0068.1 already exists. This is likely to confuse readers of docs/BACKLOG.md; consider updating the title to avoid implying it's the first child (e.g., reference the renumber or describe the scope without a child-number).
    docs/backlog/P2/B-0068.4-forge-cli-ollama-research-slice-aaron-2026-05-10.md:8
  • This child row doesn’t declare parent: B-0068, unlike the other B-0068.* siblings (e.g., docs/backlog/P2/B-0068.1-…:6, B-0068.2-…:6, B-0068.3-…:6) and many other dotted IDs (e.g., docs/backlog/P2/B-0054.1-…:9). Adding parent: B-0068 would make the relationship machine-readable and keep frontmatter consistent.
    docs/backlog/P2/B-0068.4-forge-cli-ollama-research-slice-aaron-2026-05-10.md:11
  • renumbered_reason says this cleanup is "tracked in B-0451", but there is no B-0451 backlog row in this branch, and B-0451 is referenced elsewhere as a different planned item (docs/backlog/P1/B-0449-…:136-138). To avoid a dangling/ambiguous reference, consider linking to the concrete tracking row path (once it exists) or referencing the PR/issue that tracks the cleanup instead of the bare ID.

…ries .1-.4 → .5-.8 (#3058)

* fix(backlog): resolve B-0090.x ID collisions — renumber Riven's ts-* atomic series .1-.4 → .5-.8

Second per-collision cleanup from the B-0451 sweep. Two complete
B-0090 decompositions had landed with overlapping sub-row IDs:

| Sub-ID | First filer | Second filer |
|---|---|---|
| B-0090.1 | Riven ts-worktree-survey (2026-05-10 PR #2503) | lost-substrate-3-bucket-taxonomy (2026-05-11 PR #2680) |
| B-0090.2 | Riven ts-orphan-branch-survey | worktree-branch-delta-audit |
| B-0090.3 | Riven ts-closed-pr-survey | closed-not-merged-pr-scan |
| B-0090.4 | Riven ts-draft-pr-aged-survey | cadence-and-hygiene-history-hook |

Per the external-references rule: the B-0090 parent body
(`docs/backlog/P2/B-0090-cadenced-lost-substrate-recovery-audit-aaron-2026-04-28.md`
lines 14-17 + 39-42) describes the SECOND decomposition explicitly
as canonical (3-bucket-taxonomy / worktree-delta / closed-not-merged
/ cadence-hook). The second set keeps the original IDs.

Riven's ts-* series renumbered as a unit (preserves the internal
dependency chain):

  B-0090.1 → B-0090.5  (TS worktree survey)
  B-0090.2 → B-0090.6  (TS orphan branch survey)
  B-0090.3 → B-0090.7  (TS closed-PR survey)
  B-0090.4 → B-0090.8  (TS draft-PR aged survey)

Each row's frontmatter:
- `id:` updated
- `last_updated: 2026-05-13` added
- `renumbered_from: B-0090.N` + reason recorded
- `tags:` add `renumbered`

Internal cross-references updated:
- `depends_on: [B-0090.1]` → `depends_on: [B-0090.5]` (3 sibling rows)
- Body text "Depends on B-0090.1" → "Depends on B-0090.5 (renumbered from B-0090.1)"
- Body text "unblocks B-0090.2" → "unblocks B-0090.6 (renumbered from B-0090.2)"
- Note in B-0090.8 about the original "B-0090.5 (cadence)" body
  reference (referred to a future unfilled cadence slice — would now
  be a new row not yet filed)

`docs/BACKLOG.md` regenerated.

Empirical effect (inline duplicate-ID count on the branch):

  Duplicate-ID groups: 11 → 7

(Once PR #3056's audit tool merges, future Otto can verify via
`bun tools/bg/audit-duplicate-row-ids.ts`.)

B-0451 cleanup progress: 1/12 → 5/12 (B-0068.1 in PR #3057 already
merged; B-0090.1-4 in this PR). Remaining 7: B-0370-0373 (4 cross-
priority bleed), B-0409 (3-way), B-0410, B-0411.

* fix(shard): MD032 blanks-around-lists in 2348Z shard (recurring class)

Second occurrence of the same MD032 failure mode I caught on the
2228Z shard (PR #3044). Pattern: writing a label sentence ("Each
row:") immediately followed by a bullet list with no blank line.

One-line fix. Discipline note for future tick shards: ALWAYS insert
a blank line between a label sentence and a following list.

* shard(tick): 0007Z — MD032 fix on 2348Z (recurring class); discipline-mechanization observation

Records: PR #3058 hit real markdownlint failure (MD032 on 2348Z shard,
second occurrence this session). One-line fix landed in 1b4866e.
Records the observation that this discipline isn't mechanized; lists
three mechanization options for future-Otto consideration.

…undary + remaining MD018

Two Copilot threads addressed:

1. Sub-row grep recipe (memo line 49): `grep -rnF "B-0068.1"` matched
   `B-0068.10` and `B-0068.1.1` because fixed-string match doesn't
   enforce word boundaries. Added the same portable `[^0-9.]|$`
   filter as the whole-row case, with the dot escaped in the regex
   (`B-0068\.1([^0-9.]|$)`).

2. MD018 on 0034Z line 38: I fixed `#3056` → `PR-3056` last tick
   but missed `#3065` on the next line. Reworded "PR #3057 +\n
   #3065 both" → "PR #3057 and\n   PR #3065 both" to keep the PR
   number on the same line as `PR`.

Both threads resolved.

Copilot caught a real overstatement in the procedure memo: PR #3065
was described as "bending first-merged-wins like PR #3057," but
PR #3065 actually KEPT THE EARLIER ROW (P1 set, filed 2026-05-09)
— that aligns with first-merged-wins, not bends it.

The correct framing:

- PR #3057 is the canonical example of external-references OVERRIDING
  first-merged-wins (kept the LATER Riven row because of sibling
  references).
- PR #3065 is the re-check pattern — both rules pointed the same
  direction (P1 set wins via temporal + external-refs + status-
  precedence). The session arc captured the initial-analysis-vs-
  re-examination dynamic in PR #3065's tick shard (0017Z) but the
  memo overstated the conclusion.

Updated to describe PR #3057 as the rule-bend and PR #3065 as the
re-check pattern that catches when initial instinct doesn't match
all the rules.

Also re: the sub-row grep word-boundary thread (Copilot round-3,
line 49): the recipe on line 52 already has the trailing
`B-0068\.1([^0-9.]|$)` filter from PR #3066 round-2 (commit
fa687ab). Resolving that thread without code change — the fix
is already in place; Copilot may be looking at a stale view.

Also re: the branch-behind thread (Copilot round-3, line 22):
tools/bg/audit-duplicate-row-ids.ts + B-0451 row are on origin/
main as of PR #3056 merge (f40be86). Will trigger update-branch
post-push so the PR base catches up.

…ction to memo frontmatter + 0034Z shard

Two consistency findings from Copilot round-4 on PR #3066:

1. Memo frontmatter description claimed "PRs ... #3065 shipped"
   but #3065 is still in flight. Reworded to "in-flight PR #3065"
   to match reality + match the rest of the document.

2. The 0034Z tick shard had the same precedent overstatement
   that round-3 corrected in the memo body — `PR #3057 + PR #3065
   both bent the temporal rule`. Updated to mirror the memo's
   correct framing: PR #3057 is the canonical rule-bend, PR #3065
   is the re-check pattern.

Both threads resolve. Cumulative Copilot threads resolved across
PR #3066: 11 (4+2+3+2).

Substrate-honest observation: round-4 found CONSISTENCY issues —
my round-3 correction didn't propagate to all the places the
document discussed the precedent. The pattern: each correction
needs an explicit propagation step to all dependent text. The
mechanization that would catch this is harder than markdown lint
(it's cross-document consistency, not single-file syntax).

…r-compliance set → B-0452-0455 (#3065)

* fix(backlog): resolve B-0370-0373 ID collisions — renumber P2 contributor-compliance set → B-0452-0455

Third per-collision cleanup from the B-0451 sweep. Four B-0370..B-0373
collisions form one connected cluster (parent + 3 deps inside the P2
set; cross-priority bleed against the earlier P1 set).

## The collisions

| ID | Earlier filer (P1, 2026-05-09 PR #2269) | Later filer (P2, 2026-05-11 PR #2683) |
|---|---|---|
| B-0370 | durable-computation-checkpoint-interface-extension | contributor-compliance-core-document-authoring |
| B-0371 | pages-seo-metadata-jsonld-social-preview | contributor-compliance-cross-reference-integration |
| B-0372 | pages-sitemap-robots-ai-crawler-policy | t1-t2-self-audit-and-cadenced-review-trajectories |
| B-0373 | alignment-proof-primitive-ladder-one-type-one-property | t4-t5-onboarding-and-drift-retrospective-trajectories |

## Resolution

Per first-merged-wins + external-references:

- The P1 set was filed via PR #2269 (2026-05-09) as itself a
  prior collision-resolution sweep — 2 days BEFORE the P2 set
  (PR #2683, 2026-05-11). First-merged-wins.
- B-0370 P1 and B-0373 P1 are already shipped (`status: closed`
  effectively per `[x]` checked state in `docs/BACKLOG.md`).
- External references to the P1 IDs exist in PR-history doc
  (`docs/history/pr-reviews/PR-2369-...md`) and a memory file
  (`feedback_shadow_lesson_log_otto_catches_2026_05_07.md`).
  Renumbering them would orphan those references.
- The P2 set's "external references" are internal to the set
  (B-0371/0372/0373 depend on B-0370 within the set) + the
  B-0092 parent body — all editable in this PR.

→ Keep P1 set at B-0370-0373. Renumber P2 set as a unit:

  B-0370 (P2) → B-0452
  B-0371 (P2) → B-0453
  B-0372 (P2) → B-0454
  B-0373 (P2) → B-0455

## Internal-chain remap

- B-0453.depends_on: [B-0370] → [B-0452]
- B-0454.depends_on: [B-0370] → [B-0452]
- B-0455.depends_on: [B-0370, B-0371] → [B-0452, B-0453]
- B-0092.body §Decomposition: lines 184-194 updated to new IDs
  with renumber note

Each renumbered row has `renumbered_from: B-0NNN` + reason in
frontmatter. `tags:` add `renumbered`. `last_updated: 2026-05-14`.

## Empirical effect

Inline duplicate-ID count on the branch:

  Duplicate-ID groups: 11 → 7

B-0451 cleanup progress: 1/12 → 9/12 (B-0068.1 in #3057 already
merged; B-0090.1-4 in #3058 in flight; B-0370-0373 in this PR).

Remaining 3 groups after this lands: B-0409 (3-way), B-0410,
B-0411.

keeping the P1 set (durable/SEO/sitemap/alignment, filed 2 days
earlier via PR #2269). Internal depends_on chain remapped + B-0092
parent body updated. Duplicate-ID groups: 11 → 7. B-0451 cleanup

Records: PR #3062 (Lior decomposition rule) merged. Triaged 8 "lint
failures" on PRs #3056 + #3058 as rate-limit-class (mise toolchain
installer hit 403 Forbidden). All required checks green; BLOCKED state
is just out-of-date branch. Triggered branch-update on all 3 in-flight
PRs via `PUT pulls/{N}/update-branch`. Declined to pick next B-0451

* fix(shard): MD032 blanks-around-lists in 0017Z + 0024Z shards (4th occurrence)

Third + fourth occurrences of the same MD032 failure mode this
session (after PR #3044 fixed 2228Z and PR #3058 fixed 2348Z).

Two more tick shards on PR #3065 hit the same pattern:
- 0017Z:51 "Plus:" → "- `B-0092` parent body..."
- 0024Z:66 "infra issues that resolve when:" → "1. The installation..."

The discipline ("blank line before lists") is in-head but unmechanized.
Per the 0007Z shard observation: mechanization options include a
pre-commit hook OR shard-writer helper. The recurrence rate suggests
the cost of mechanization is now lower than the cost of the
recurring CI-cycle-per-tick-shard.

Filing as observation in commit message; not expanding scope to
build the mechanization this tick.

* docs(backlog): B-0456 — mechanize MD032 blanks-around-lists check

Files the discipline-gap observation from this session's 4 MD032
recurrences. Per encoding-rules-without-mechanizing.md, the cost-
benefit has tipped: building a small TS helper under tools/hygiene/
is now cheaper than the recurring CI-cycle-per-tick-shard cost.

Row captures:
- The 4 historical occurrences (2228Z PR #3044, 2348Z PR #3058,
  0017Z + 0024Z PR #3065) as test fixtures
- Two mechanization options: pre-push git hook (preferred) or
  tick-close ritual check (fallback)
- Acceptance criteria covering clean fixture, single/multi finding,
  no-lists, list-without-preceding-label edge cases
- Composes-with pointers to B-0451 sweep + Rule 0 + the
  encoding-rules-without-mechanizing rule

Not building the mechanization THIS tick (3 PRs already in flight;
restraint discipline). The row makes the work pick-up-able by any
future agent without session context.

* shard(tick): 0046Z — 3 PRs landed (#3056, #3058, #3059); 4th MD032 forces B-0456

Records: PRs #3056 (audit tool + B-0451), #3058 (B-0090.x batch),
and Otto-Desktop's #3059 all merged this tick. PR #3065 hit real
markdownlint failure (MD032 ×2 on prior tick shards) — fixed inline.
Filed B-0456 to mechanize the recurring MD032-on-tick-shard
discipline gap (4 occurrences this session).

Restraint discipline maintained: did NOT build the mechanization

+ acceptance criteria for future tick pickup.

* fix(backlog): MD038 in B-0456 — replace `- ` code spans with prose descriptions

The B-0456 row's "Examples this session" table used backtick-quoted
`- ` (hyphen followed by space) as the bullet-pattern marker. The
trailing space inside the code span triggers markdownlint MD038
"no-space-in-code".

Replaced the literal-bullet code spans with prose descriptions
(`bullet-list-with-no-blank-line` / `numbered-list-with-no-blank-line`)
that convey the same meaning without the trailing-space-in-code-span
hazard.

5th markdown lint finding this session (MD038 added to the
MD032 ×4 + MD018 ×1 cluster). Strengthens B-0456's case further
— the future TS helper should check MD038 + MD032 + MD018 at minimum.

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0100Z — MD038 fix on B-0456 row; 6 markdown findings this session

Records: PR #3064 (Otto-Desktop B-0442 slice 6) merged. PR #3065 hit
MD038 lint failure on B-0456 row's Examples table (trailing space
in `- ` code span). Fixed by replacing code-span markers with prose
descriptions. Recurrence-count update: 6 markdown findings this
session (MD032 ×4 + MD018 ×1 + MD038 ×1).

Substrate-honest observation: the automated review (Copilot +
markdownlint + audit-duplicate-row-ids) is doing structural work my
own attention can't sustain at this PR cadence. The automated
review IS the discipline; agent role is responding to findings.

* fix(shard): MD032 in 0100Z — `+ memory` line-start parsed as list item

The 0100Z tick shard's recurrence-count summary ended with
"...this session's tick shards" and continued on the next line
with "+ memory + backlog rows.**". Markdownlint parsed the leading
`+ ` as a list marker, firing MD032 (preceding line is bold text,
not a blank).

Rephrased to "tick shards, memory files, and backlog rows" so no
line starts with a list marker.

8th markdown lint finding this session. 5th MD032 specifically.
B-0456 mechanization argument continues to strengthen.

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0117Z — 8th markdown finding (MD032 ×5) + 2 Copilot rounds resolved

Records: PR #3065 hit MD032 on 0100Z line 46 (`+ memory` line-start
parsed as list item, 5th MD032 this session); fixed in 54d8ff0.
PR #3066 had 2 unresolved Copilot threads: sub-row grep recipe
word-boundary issue + remaining MD018 on `#3065` line-start; fixed
in fa687ab + both threads resolved.

Preemptively escaped `[^0-9.]|$` to `[^0-9.]\|$` in this shard's
own table to avoid the same MD056 issue that 0054Z hit.

9 total markdown findings this session. The session arc has
accidentally become the regression suite for B-0456's mechanization.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(shard): MD038 ×3 in 0117Z — replace inline-code "+ " markers with prose

Same MD038 (no-space-in-code) class as the B-0456 row fix from
earlier this session (PR #3065 commit cbbfbb6). The 0117Z shard
described the previous tick's MD032 fix using inline-code
literals `` `+ ` `` (backtick + plus + space + backtick) in three
places — the trailing space inside the code span trips MD038.

Replaced with prose: "a plus-space (\"+\" followed by a space)".

Meta-observation: the 0117Z shard whose entire point was discussing
MD038/MD032 fixes itself contained 3 MD038 violations. This is the
recursive-finding pattern documented earlier. The discipline of
"avoid trailing-space-inside-code-span" is in-head but only
catches the patterns I've seen recently — the `+ ` form was new
to my pattern-match this tick.

10th MD finding this session. The break-even argument from B-0456
keeps strengthening; future agent picking it up gets a 4-rule-class
corpus (MD032 + MD018 + MD038 + MD056).

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0132Z — 10th MD finding (MD038 ×3); recursive-finding pattern continues

Records: PR #3065 hit MD038 ×3 on the 0117Z shard (inline-code
plus-space literals with trailing space). Fixed by replacing with
prose ("a plus-space"). Total markdown findings this session: 12
(MD032 ×5 + MD018 ×2 + MD038 ×4 + MD056 ×1) across 4 rule classes.

Meta-pattern: shards describing markdown lint fixes tend to
themselves contain markdown lint findings of related classes.
The 0117Z shard whose point was MD032 + MD018 + MD038 + MD056
discussion contained 3 new MD038 hits.

This shard authored carefully to avoid backtick-quoted bullet/list
markers entirely — preemptive vs reactive discipline.

…ate from session arc) (#3066)

* docs(memory): B-0451 per-collision renumber procedure (durable substrate from session arc)

Captures the procedure pattern that emerged from this session's 5
ID-collision-resolution PRs (#3053 B-0444, #3057 B-0068.1, #3058
B-0090.x, #3065 B-0370-0373, plus the in-flight audit tool #3056).

Key precedence rule documented: **external-references trumps
first-merged-wins**. The row that would cost more to migrate keeps
its ID, regardless of who filed first. Both PR #3057 and PR #3065
bent first-merged-wins this way after re-examining external refs.

9-step recipe covers:
1. Identify colliding rows via audit-duplicate-row-ids.ts
2. Find external references (parent body, sibling depends_on, memory,
   PR history, BACKLOG.md)
3. Apply precedence rules in order (external-refs > first-merged >
   status-precedence)
4. Pick next-free IDs (check origin/main AND open PRs)
5. Create isolated worktree (multi-Otto split-brain prevention)
6. Rename files + edit frontmatter (`renumbered_from:` + reason)
7. Batch connected components (preserve internal dep chain)
8. Update parent's body + regen BACKLOG.md
9. Verify + commit + push + PR

Three substrate-honest pitfalls documented:
- BLOCKED ≠ failed CI (often just branch-out-of-date)
- Initial analysis can point wrong (re-examine when rules disagree)
- ID collisions hide in substrate for weeks (run audit BEFORE filing)

Remaining work captured: 3 collision groups (B-0409 3-way, B-0410,
B-0411) — all 2026-05-11 pre-claim-acquire-rule decomposition races.
Each takes ~5-10 min following this procedure.

This is a low-rate-limit-cost substrate landing (memory file +
generated index regen avoided) chosen this tick over picking
another cleanup PR per the previous tick's restraint discipline.

* shard(tick): 0034Z — B-0451 procedure memory landed as durable substrate

Records: captured the per-collision renumber procedure from the
session's 5 collision-resolution PRs into a 242-line memory file
(PR #3066). Procedure distills external-references-trumps-first-
merged precedence rule + 9-step recipe + 3 substrate-honest pitfalls
+ remaining-work map (3 collision groups for future tick).

Restraint discipline continued: did NOT open another cleanup PR
this tick. Memory file is the low-rate-limit-cost durable
alternative.

* fix(memory): address Copilot review + frontmatter + MD018 on PR #3066

Four issues addressed:

1. **Required `created:` frontmatter field added** — memory file was
   missing it (caught by check-memory-frontmatter-completeness CI
   workflow; the reindexer requires name/description/type/created).

2. **MD018 on 0034Z.md:35** — line started with `#3056)` which
   markdownlint parsed as a malformed ATX heading. Reworded
   PR-number references to `PR-3056` style in that one paragraph
   to avoid the line-start hazard.

3. **Copilot review (grep recipe portability)** — the original
   `grep -rn "B-0XXX\b" ...` recipe treats the ID as regex (so
   `B-0068.1` `.` matches any character) AND uses `\b` which is a
   GNU-grep extension not portable to BSD grep on macOS. Replaced
   with `grep -rnF` (fixed-string match) + a portable word-boundary
   filter `[^0-9.]|$`. Documented both whole-row and sub-row ID
   cases explicitly.

4. **Copilot review (branch-behind state)** — separate concern;
   resolved by `gh api -X PUT pulls/3066/update-branch` (audit tool
   + B-0451 row are on origin/main; the branch was just out-of-date).
   Triggered post-commit.

* shard(tick): 0054Z — PR #3066 Copilot review caught 4 real issues

Records: PR #3066 surfaced 2 reviewer threads + 2 CI failures, all
real and addressable. Fixed in 21dc986:
- Added missing `created:` frontmatter field (CI workflow requires)
- Reworded `#3056)` line-start to avoid MD018 ATX-heading false-parse
- Replaced GNU-grep `\b` recipe with portable `[^0-9.]|$` filter +
  fixed-string `-F` for sub-row IDs
- Resolved both Copilot threads

5 MD-class lint findings this session strengthen B-0456's case
(MD032 ×4 + MD018 ×1).

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(shard): MD056 in 0054Z — escape pipe in markdown table cell

The 0054Z tick shard described the grep recipe fix using `[^0-9.]|$`
in a markdown-table cell. The unescaped pipe was interpreted as a
column separator, producing a 4-column row in a 3-column table.

Escaped to `[^0-9.]\|$`.

7th markdown lint finding this session (MD056 added to the
MD032 ×4 + MD018 ×1 + MD038 ×1 cluster). Pattern: tick shards
describing fixes-for-other-lint-rules tend to themselves hit
markdown lint rules they didn't anticipate. Strengthens B-0456's
case further — the future TS helper should at least check
MD032 + MD018 + MD038 + MD056 to cover the observed pattern.

* shard(tick): 0110Z — 7th markdown finding (MD056); meta-recursion observation

Records: PR #3066 hit MD056 on 0054Z shard (unescaped pipe in table
cell describing the grep recipe). 7th markdown lint finding this
session. Captures the meta-recursion pattern: tick shards describing
markdown-lint fixes tend to themselves hit lint rules the fix didn't
anticipate.

Break-even-on-mechanization analysis: occurrence #7 of 10 needed
to make the B-0456 mechanization unambiguously the cheaper path.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(memory/shard): Copilot round-2 on PR #3066 — sub-row grep word-boundary + remaining MD018

Two Copilot threads addressed:

1. Sub-row grep recipe (memo line 49): `grep -rnF "B-0068.1"` matched
   `B-0068.10` and `B-0068.1.1` because fixed-string match doesn't
   enforce word boundaries. Added the same portable `[^0-9.]|$`
   filter as the whole-row case, with the dot escaped in the regex
   (`B-0068\.1([^0-9.]|$)`).

2. MD018 on 0034Z line 38: I fixed `#3056` → `PR-3056` last tick
   but missed `#3065` on the next line. Reworded "PR #3057 +\n
   #3065 both" → "PR #3057 and\n   PR #3065 both" to keep the PR
   number on the same line as `PR`.

Both threads resolved.

* fix(memory): Copilot round-3 — correct PR #3065 precedent description

Copilot caught a real overstatement in the procedure memo: PR #3065
was described as "bending first-merged-wins like PR #3057," but
PR #3065 actually KEPT THE EARLIER ROW (P1 set, filed 2026-05-09)
— that aligns with first-merged-wins, not bends it.

The correct framing:

- PR #3057 is the canonical example of external-references OVERRIDING
  first-merged-wins (kept the LATER Riven row because of sibling
  references).
- PR #3065 is the re-check pattern — both rules pointed the same
  direction (P1 set wins via temporal + external-refs + status-
  precedence). The session arc captured the initial-analysis-vs-
  re-examination dynamic in PR #3065's tick shard (0017Z) but the
  memo overstated the conclusion.

Updated to describe PR #3057 as the rule-bend and PR #3065 as the
re-check pattern that catches when initial instinct doesn't match
all the rules.

Also re: the sub-row grep word-boundary thread (Copilot round-3,
line 49): the recipe on line 52 already has the trailing
`B-0068\.1([^0-9.]|$)` filter from PR #3066 round-2 (commit
fa687ab). Resolving that thread without code change — the fix
is already in place; Copilot may be looking at a stale view.

Also re: the branch-behind thread (Copilot round-3, line 22):
tools/bg/audit-duplicate-row-ids.ts + B-0451 row are on origin/
main as of PR #3056 merge (f40be86). Will trigger update-branch
post-push so the PR base catches up.

* shard(tick): 0125Z — Copilot round-3 substantive correction on PR #3066

Records: 3 new Copilot threads on PR #3066. Triaged: 1 mechanical
(branch-behind, resolved via update-branch), 1 stale-view (sub-row
recipe fix already in place since round-2), 1 substantive (memo
overstated PR #3065 as bending first-merged-wins when it actually
aligned).

The substantive correction history: 0017Z shard initial analysis
pointed wrong → same shard re-examination corrected → procedure
memo then overstated → this tick's commit corrected. 4-step
correction trajectory captured in the substrate.

3 PR-3066 threads resolved (cumulative: 9 across 3 review rounds).

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(memory/shard): Copilot round-4 — propagate PR #3065 framing correction to memo frontmatter + 0034Z shard

Two consistency findings from Copilot round-4 on PR #3066:

1. Memo frontmatter description claimed "PRs ... #3065 shipped"
   but #3065 is still in flight. Reworded to "in-flight PR #3065"
   to match reality + match the rest of the document.

2. The 0034Z tick shard had the same precedent overstatement
   that round-3 corrected in the memo body — `PR #3057 + PR #3065
   both bent the temporal rule`. Updated to mirror the memo's
   correct framing: PR #3057 is the canonical rule-bend, PR #3065
   is the re-check pattern.

Both threads resolve. Cumulative Copilot threads resolved across
PR #3066: 11 (4+2+3+2).

Substrate-honest observation: round-4 found CONSISTENCY issues —
my round-3 correction didn't propagate to all the places the
document discussed the precedent. The pattern: each correction
needs an explicit propagation step to all dependent text. The
mechanization that would catch this is harder than markdown lint
(it's cross-document consistency, not single-file syntax).

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0140Z — Copilot round-4 (cross-document consistency)

Records: 2 round-4 Copilot threads on PR #3066, both consistency
issues (round-3 correction didn't propagate to memo frontmatter +
0034Z shard). Fixed in dce450e + both threads resolved.

Finding-class shift across rounds: factual → semantic →
interpretive → consistency-drift. Each round catches what the
prior fix-in-one-place missed.

Cumulative PR #3066 threads resolved: 11 across 4 rounds.

* shard(tick): 0153Z — PR #3065 merged; substrate-hygiene cascade close-out

Records: PR #3065 (B-0370-0373 P2 renumber + B-0456 row + multi-
lint fixes) merged to main (02d75a3). Session-arc final state:

- 20 PRs merged (11 mine substrate-hygiene cascade + 9 sibling agents)
- 1 PR closed-with-provenance (#3052)
- 1 PR in flight (#3066 procedure memo, wait-ci, threads-clear)
- Duplicate-ID groups: 12 → 3 on main
- Dangling-dep refs: 9 → 0 (earlier this session)
- Markdown findings caught: 12 across 4 rule classes
- Copilot review rounds metabolized on #3066: 4 (11 cumulative threads)

3 remaining ID collisions (B-0409 3-way, B-0410, B-0411) are
pick-up-able via the procedure memo in PR #3066. B-0456
mechanization filed with 12-finding regression suite.

Restraint discipline: declined to pick another cleanup this tick.
The procedure memo + B-0451 row + B-0456 row make all remaining
work pick-up-able by any future tick.

…rate-hygiene sweep (#3073)

* fix(backlog): resolve B-0409 3-way collision — completes B-0451 substrate-hygiene sweep

Fifth and FINAL per-collision cleanup from the B-0451 sweep. Three
rows shared id: B-0409:

| Row | Filed | Scope |
|---|---|---|
| P1 wallet-immune-system | 2026-05-11 10:48 PR #2709 | Wallet immune system spec (L-effort) |
| P2 amara-persona-bootstrap | 2026-05-11 10:34 PR #2704 | B-0118 amara series atomic child |
| P2 peer-call-ts-audit | 2026-05-11 10:58 PR #2706 | B-0120 peer-call series atomic child |

## Resolution: keep peer-call series at B-0409

Per external-references rule:

- B-0120 frontmatter has `children: [B-0409, B-0410, B-0411, ...]`
  AND `depends_on: [B-0409, B-0410, ...]` — strongest references
- B-0118 has body-text mentions only (editable in this PR)
- Wallet-immune row has no incoming refs from other rows
  (composes_with B-0294/B-0321 point FROM the wallet row, not TO it)

→ Keep peer-call B-0409. Renumber:

  amara B-0409 → B-0459 (completes the amara series renumber
    started in PR #3069: B-0410 → B-0457, B-0411 → B-0458, and
    now B-0409 → B-0459)
  wallet-immune-system B-0409 → B-0460

## Chain remap

PR #3069 left B-0457's `depends_on: [B-0409]` pointing at the
soon-to-be-renumbered amara B-0409. This PR remaps it:

  B-0457.depends_on: [B-0409] → [B-0459]
  B-0457.composes_with: ..., B-0409, ... → ..., B-0459, ...

Plus B-0118 parent body §Decomposition updated:

  "B-0409 — Amara persona bootstrap definition" →
  "B-0459 (renumbered from B-0409) — Amara persona bootstrap definition"

`docs/BACKLOG.md` regenerated.

## Empirical effect (CASCADE COMPLETE)

```
$ bun tools/bg/audit-duplicate-row-ids.ts
audit-duplicate-row-ids: 561 rows with id field, no duplicate IDs
```

**Down from 12 duplicate-ID groups at session start to 0 on main.**

B-0451 cleanup progress: 11/12 → **12/12** (sweep complete).

## Session-arc cascade rounds

Round 1: B-0444 P1+P2 (PR #3053) — 12 → 11 groups
Round 2: B-0068.1 (PR #3057) — 11 → 10 groups
Round 3: B-0090.1-4 batch (PR #3058) — 10 → 6 groups
Round 4: B-0370-0373 P2 batch (PR #3065) — 6 → 3 groups
Round 5: B-0410-B-0411 amara batch (PR #3069) — 3 → 1 group
**Round 6: B-0409 3-way (THIS PR) — 1 → 0 groups**

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0223Z — B-0451 substrate-hygiene cascade COMPLETE (12 → 0 groups)

Records: PR #3069 merged (ed9284d). Cross-PR sequencing constraint
cleared. Executed the final B-0409 3-way cleanup in PR #3073.

audit-duplicate-row-ids on the branch reports: 561 rows with id
field, NO DUPLICATE IDs. The substrate-hygiene cascade reaches its
terminal state once PR #3073 lands.

Session-arc final metrics:
- 14 of my PRs merged in the substrate-hygiene cascade
- 11 sibling-agent PRs merged (Otto-Desktop, Lior, Codex)
- 1 PR in flight (#3073), 1 closed-with-provenance (#3052)
- Duplicate-ID groups: 12 → 0
- Dangling-dep refs: 9 → 0
- 12 markdown findings caught across 4 rule classes
- 4 Copilot review rounds metabolized on PR #3066 (11 threads)
- New tooling: audit-duplicate-row-ids.ts
- New durable substrate: procedure memo + B-0451 + B-0456

The work + procedure are durable; future-Otto can pick up B-0456
mechanization or any new findings via the canonical reference.

* fix(backlog): bump renumber to B-0462/B-0463 (avoid PR #3070's B-0459-B-0461 reservation) + fix B-0457 body refs

Three issues addressed in one commit:

1. **PR #3070 just merged** (2026-05-14) and reserved B-0459/0460/0461
   for B-0449 slice 5+ follow-up work (Otto-Desktop's B-0449 body
   text now points at those numbers). My initial renumber claimed
   B-0459 (amara) + B-0460 (wallet-immune) — same collision pattern
   that started this whole sweep, recurring at meta level. Bumped
   to next-available: B-0462 (amara) + B-0463 (wallet-immune).

2. **Codex P2 + Copilot threads on B-0457**: I updated B-0457's
   frontmatter `depends_on: [B-0409] → [B-0459]` but the body text
   still referenced `B-0409` for the preamble source ("Use preamble
   from B-0409"). After this PR's renumber, B-0409 belongs to a
   different peer-call-ts-audit row, so the instruction would point
   at the wrong artifact. Updated B-0457 body to "Use preamble from
   B-0462 (renumbered from B-0409 per B-0451 sweep)" — same in the
   Evidence section.

3. **B-0118 parent body**: Updated 3 places from B-0459 → B-0462 to
   match the new renumber target.

## Final state

```
$ bun tools/bg/audit-duplicate-row-ids.ts
audit-duplicate-row-ids: 561 rows with id field, no duplicate IDs
```

The cascade still terminates at zero collisions; just with B-0462
+ B-0463 instead of B-0459 + B-0460.

## Substrate-honest meta-observation

Otto-Desktop's PR #3070 + my PR #3073 ran in parallel and BOTH
reached for the same next-free range (B-0459-0461). The audit tool
prevents file-level collisions (same id field in two rows) but
doesn't prevent reservation-level collisions (one PR's body text
says "we plan to use X" while another PR makes X canonical for
different content). This is the next failure class — captured in
this commit message for B-0456 follow-up consideration.

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0238Z — caught parallel-renumber-collision with PR #3070; bumped to B-0462/0463

Records: PR #3070 (Otto-Desktop's B-0449 slice-5 reservation
renumber) merged, reserving B-0459/0460/0461. My PR #3073 was
reaching for B-0459/B-0460 — same collision pattern recurring at
meta level. Bumped to B-0462/B-0463.

Also resolved 2 Codex/Copilot threads on B-0457 body refs (real
bugs — frontmatter updated but body text still pointed at B-0409).

Meta-observation captured: audit tool catches file-level
collisions but doesn't catch reservation-level collisions where
one PR's body text says "plan to use X" while another PR makes X
canonical for different content. Next failure class for B-0456
follow-up consideration.

* fix(shard): 0223Z — annotate superseded IDs (Copilot+Codex round-1 consistency catch)

Three Copilot/Codex threads converged on the same finding: the 0223Z
tick shard described the renumber as B-0459/B-0460 (the initial
plan) but the PR's final renumber bumped to B-0462/B-0463 (per
0238Z's catch of PR #3070's reservation collision). Without this
annotation, future readers following the 0223Z trail would land on
the wrong IDs.

Added SUPERSEDED annotations inline + a note pointing at 0238Z for
the bump narrative. The PR body has also been updated to reflect
the final IDs.

Cumulative threads resolved across this PR: 3 (Copilot round-1).

Co-Authored-By: Claude <noreply@anthropic.com>

* shard(tick): 0303Z — PR #3073 round-1 review: 3 cross-shard consistency findings

Records: Copilot/Codex caught 3 consistency findings on PR #3073.
Same finding-class as PR #3066's round-4 (cross-document drift after
mid-PR correction). Fixed in 6006bab: 0223Z shard annotated with
SUPERSEDED + pointer to 0238Z; PR body updated to final IDs.

This shard was pre-validated by check-md032-blanks-around-lists.ts
(the B-0456 helper from PR #3075) before push: "1 file(s) scanned,
no MD032 findings".
