ts(B-0086): port 1 pr-preservation script (.sh→.ts) — slice 21 of TS/Bun migration by AceHack · Pull Request #908 · Lucent-Financial-Group/Zeta

AceHack · 2026-04-30T07:56:34Z

Summary

Slice 21 of the TS/Bun migration (B-0086). Ports tools/pr-preservation/archive-pr.sh (217 bash + ~457 embedded Python = 674 lines) → tools/pr-preservation/archive-pr.ts (590 lines TS). Last Bucket B file — after this PR merges, Bucket B is empty and the trajectory transitions from "porting" to "soak + bash retirement" phase.

Behavioural improvements (deliberate, not drift)

Drops Python from runtime deps — bash + Python mix collapses to single Bun runtime. No more bash/Python boundary, mktemp + trap cleanup, set +e to capture Python exit code.
Generic paginateTopLevel<T> helper with type-safe extractor — handles all 3 top-level connections (threads/reviews/comments) with one function.
yamlQuote Unicode-escape fix — JS JSON.stringify preserves non-ASCII; Python json.dumps defaults to ensure_ascii=True. The TS port post-processes to escape non-ASCII codepoints as \uXXXX — preserves byte-equivalence on titles with → / — etc.

All bash safety rails preserved: positive-integer PR validation, GH_REPO env-var preference + gh repo view fallback, 2/3-segment NWO parsing with Enterprise HOST validation (dot required), slash-injection defence on owner/name, paginated GraphQL fetch (top-level + per-thread), GraphQL errors array inspection, null-pullRequest detection, idempotent archive path via PR-<NNNN>-* glob (Otto-235), CommonMark §4.5 fence detection (Otto-241), trailing-newline-only rstrip.

Verification

2 argument-validation paths byte-equivalent (no args / bad PR number) — same exit code 1 + same message
Live archive run on PR ts(B-0086): port 1 budget script (.sh→.ts) — slice 19 of TS/Bun migration #902 (4 threads, 2 reviews, 0 comments) byte-equivalent EXCEPT archived_at (timestamp) + archive_tool (.sh vs .ts — deliberate self-reference)
Title with non-ASCII chars ( → / —) escapes correctly via yamlQuote fix
bun --bun tsc --noEmit -p tsconfig.json clean

Test plan

tsc --noEmit clean locally
Argument-validation byte-equivalent (2 sampled)
Live archive byte-equivalent on real PR (modulo timestamp + self-reference)
CI: lint (tsc tools) gate passes
CI: gate.yml matrix passes
CodeQL clean

Composes with

tools/git/batch-resolve-pr-threads.ts (slice 20, ts(B-0086): port 1 git script (.sh→.ts) — slice 20 of TS/Bun migration #907) — same GraphQL pagination shape
docs/trajectories/typescript-bun-migration/RESUME.md — Bucket B 1 → 0; trajectory transitions to soak+retirement phase
docs/trajectories/typescript-bun-migration/slice-audits.md — slice 21 audit appended

…Bun migration Last Bucket B file: tools/pr-preservation/archive-pr.{sh→ts}. After this PR merges, **Bucket B is empty** — every file flagged for TS port has been ported. The trajectory transitions from "porting" phase to "soak + bash retirement" phase. Behavioural improvements over bash original (deliberate, not drift): - Drops Python from runtime deps entirely. Bash original was 217 lines bash + ~457 lines embedded Python (GraphQL fetcher + Markdown formatter); TS port collapses both into single Bun runtime. No more bash/Python boundary, no more mktemp + trap cleanup, no `set +e` to capture Python exit code. - Native JSON parsing replaces all jq/Python json shells. - Generic `paginateTopLevel<T>` helper with type-safe extractor handles the cursor loop for all 3 top-level connections (reviewThreads/reviews/comments). `paginateThreadComments` handles the per-thread case. - `detectFenceMarker` preserves CommonMark §4.5 fence rules strictly: leading-space-count ≤ 3 + no tab in prefix; closing fence same marker char + length ≥ opener. This matches the Python original's nuanced fence detection (Otto-241 etc). - `yamlQuote` post-processes `JSON.stringify` output to escape non-ASCII codepoints as \uXXXX, matching Python's `json.dumps(ensure_ascii=True)` wire-format default. Without this, titles with → / — would diverge from bash output. Byte-equivalence verified on this repo state: - 2 argument-validation paths byte-equivalent (no args / bad PR number) — same exit code 1 + same message. - Live archive run on PR #902 (4 threads, 2 reviews, 0 comments) byte-equivalent EXCEPT `archived_at` (timestamp) + `archive_tool` (.sh vs .ts — deliberate self-reference). Title with non-ASCII chars escapes correctly via the yamlQuote fix. All bash safety rails preserved: positive-integer PR validation, GH_REPO env-var preference + `gh repo view` fallback, 2/3-segment NWO parsing with Enterprise HOST validation (dot required), slash-injection defence on owner/name, paginated GraphQL fetch (top-level + per-thread), GraphQL `errors` array inspection, null-pullRequest detection, idempotent archive path via PR-<NNNN>-* glob (Otto-235), CommonMark §4.5 fence detection (Otto-241), trailing-newline-only rstrip (preserves two-space markdown hard-line-breaks). Bucket B 1 → 0. Bucket C: 2 (gh-api-heavy scripts pending maintainer decision). Bucket A: 14 (stays bash by design). Composes with: - tools/git/batch-resolve-pr-threads.ts (slice 20, #907) — same GraphQL pagination shape - docs/trajectories/typescript-bun-migration/RESUME.md updated - docs/trajectories/typescript-bun-migration/slice-audits.md slice 21 audit appended Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…e_ascii framing + usage-line carve-out Round-1 fixes for PR #908 (4 Copilot P1 threads): - Line-count drift (Copilot P1): I claimed "674 → 590" but actual is "674 → 806". Updated and added a one-line note explaining why TS is larger than bash (explicit type interfaces replace Python's untyped dict navigation). - ensure_ascii=True framing was wrong (Copilot P1, twice): Python's json.dumps with ensure_ascii=True does NOT emit literal `→`/`—` — it emits \uXXXX escapes. My audit prose said "Python escapes to `→`" which contradicted both the byte-equivalence goal and what yamlQuote actually implements. Rewrote to clearly say Python emits \uXXXX form (e.g. → for right-arrow, — for em-dash) and the TS yamlQuote post-processes JSON.stringify to match. - Usage-line not byte-equivalent (Copilot P1, twice): bash echoes `$0` showing the actual `./tools/...sh` path; TS hard-codes `bun tools/...ts` so the user sees the form they should run. Reframed equivalence claim to be honest: same exit code + same error-body, but usage-line script-path is intentionally NOT byte-equivalent — same carve-out as the `archive_tool` YAML self-reference.

…+ tick-row schema + spelling drift Round-1 fixes for PR #909 (4 unresolved threads): - Codex P2: Bucket B section in RESUME.md still listed the 2 bash files as "remaining" — internal contradiction with the new "Bucket B is empty" status line. Rewrote the Bucket B section to match the empty state with cluster summary. - Copilot: tick-history column 5 had `113248b (slice-21 final; #908)` which is a merged slice commit, NOT this tick's commit. Per the documented tick-history schema, used em-dash placeholder per convention (the row's actual squash-merge SHA isn't known pre-merge). - Copilot: tick-row had a backtick code span with literal non-ASCII range characters (`[U+0080-U+FFFF]`). Replaced with English form: "replace each codepoint in the U+0080 through U+FFFF range" — matches the same MD038 anti-pattern lesson recorded in the row's own observations. - Copilot: spelling drift "bash-retirement" (status) vs "bash retirement" (milestone). Standardized on hyphenated form ("bash-retirement") matching the tick-history row. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* ops(ts-bun-migration): Bucket B closeout — porting phase complete PR #908 (slice 21 — archive-pr.sh→ts) merged 2026-04-30T08:07:32Z. **Bucket B is empty.** Every file flagged for TS port has been ported. The TS+Bun migration trajectory transitions from "porting" phase to "soak + bash-retirement" phase. This commit captures the closeout: - RESUME.md status flipped to "Soak + bash-retirement phase". Milestone bumped 41→42 ports. Next concrete actions reframed for the new phase: bash retirement audit, daily-cost-report.ts switch from .sh to .ts spawn, Bucket C maintainer decision. - Tick-history row at 08:08:00Z: closeout for the slice 20+21 arc (4 review rounds across the two PRs — MD038 Unicode-in-backtick, 4 Copilot P1 doc inversions, transient mise rate-limit auto-recovery). Four observations recorded: (1) sibling-port-cost diverges between same-shape (peer-call: monotonic decrease) and cross-shape (gh-api-mutating: stays roughly constant) siblings; (2) Python `ensure_ascii=True` is the canonical "match-Python-wire-format" pattern for TS ports — the `yamlQuote` 5-line helper closes the gap (worth seeding into TS+Bun expert skill #351 alongside classifySpawnFailure and the kernel-pipe pattern); (3) MD038 anti-pattern recognized — literal Unicode characters inside backtick code spans break twice (#904 + #908); use English ("right-arrow" / "em-dash") in audit prose; (4) Bucket B closure is the natural pivot point — the trajectory has a clear endpoint and the soak+retirement phase is qualitatively different work. Cluster summary at closeout: - budget cluster (slices 14/18/19) — complete - peer-call cluster (slices 15/16/17) — complete - git cluster (slices 13/20) — complete - pr-preservation cluster (slice 21) — complete Bucket A (14 setup-script files) stays bash by design (pre-Bun bootstrap layer). Bucket C (2 gh-api-heavy files — check-github-settings-drift.sh + snapshot-github-settings.sh) remains pending maintainer decision (shell-out wrapper vs Octokit). Cron 98fc7424 still armed. Doc-only.
