🚀 Release 0.1.2

The release commit message is a machine-read convention (release-gate
in ci.yml skips the redundant main CI run on it), so the emoji carries
weight: change the mint in scripts/release.sh, the recognized pattern,
and both docs in one atomic commit. No tags or release commits exist
yet, so nothing historical parses differently. 🚀 matches the
gitmoji semantic (deploy/publish) better than 🔖 here.

 - **While iterating:** `npm run test` (`check:tsc` + the unit suite) for fast feedback on the files you changed.
+- **Optional code intelligence:** this repo installs `@spences10/pi-lsp` (pinned in `.pi/settings.json`) as a project-local pi extension. It talks to the repo's own TypeScript 7 via `tsc --lsp --stdio` and exposes **read-only** tools — `lsp_hover`, `lsp_definition`, `lsp_references`, `lsp_find_symbol`, `lsp_document_symbols`, `lsp_diagnostics(_many)`. Prefer `lsp_references` over `grep -w` for widely-colliding identifiers (`matches`, `type`, …); use `lsp_hover` to read inferred types on generic-heavy code. It has no rename / code-action / apply-edit surface — the write side is pi's `edit` tool + `check:tsc`. Treat empty LSP output as _inconclusive_, not success: **`npm run test` / `npm run verify` remain the sole authoritative gate** (see the next bullet). The server keeps running across that gate with a ~5 min idle timeout and registers no file watchers, so if you change `tsconfig.json` / `package.json` mid-session its diagnostics can be stale — when LSP output disagrees with `check:tsc`, trust `check:tsc` and restart pi (or wait out the idle timeout) before concluding the LSP is wrong.
 - **Definition of done — run this before you call the work finished:** `npm run verify`. If all green, commit. If red, look at the output, fix the root cause, and re-run.
 - **On commit:** write a good message (see [CONTRIBUTING.md § Commit messages](./CONTRIBUTING.md#commit-messages)). Lefthook's pre-commit hook already runs the fast, offline, staged-file checks — don't run them by hand. If the hook fails on style, `npm run fix`, restage, recommit.
 - **`npm run maintain` is NOT part of the feature loop.** Its scans are advisory, never a gate; run them only on an explicit maintenance / update-deps branch.

TypeScript can express it; that's the intended tool. The `oxlint-disable`-location rule in [CONTRIBUTING.md § Rules the tools don't enforce](./CONTRIBUTING.md#rules-the-tools-dont-enforce) is a **human** last-resort convention (so a reviewer can spot a deliberate suppression) — it is not permission for you to add one. If the types genuinely cannot express something, stop and surface the conflict (commit message / handover) rather than suppress it.
 
 The same applies to the checks themselves: **never `git commit --no-verify`** (or otherwise skip a pre-commit / pre-push hook). The checks are fast and offline, so a redundant run is fine — bypassing a hook to get green is the identical anti-pattern. If a commit already skipped a hook, redo it through one: `git reset --soft HEAD~1 && git commit -C <skipped-sha>`.
 
 Never start a long-lived / blocking process such as `npm run watch`. It runs until a human stops it with Ctrl-C, so in an agent turn it hangs forever and floods the context with continuous output. Reach for a one-shot command instead — `npm run test` (or `npm run check`) — to get feedback.
 
+## Backlog
+
+`backlog.tasks` uses the vscode-todotasks format (not Markdown). A line ending in `:` is a project; every other line is a task. Status glyphs: `☐` open, `✔` done, `✘` cancelled; subtasks nest by indentation. Inline `@tags` carry metadata — `@done` / `@cancelled` mark completion, `@critical` / `@high` / `@low` / `@today` set priority. The `(…)` timestamp after `@done` is editor-generated: omit it when checking off by hand.
+
+**Required coupling:** a `✔` line _must_ also carry `@done`, and a `✘` line _must_ carry `@cancelled`. The `sandy081.todotasks` extension treats the glyph as the completion signal, then unconditionally searches for the matching tag to decorate; a bare `✔`/`✘` with no tag makes it compute an illegal `Range` (negative character offset) that throws and kills all highlighting/decoration for the document. A `☐` may stand alone. So check off by hand as `✔ … @done` (optionally `@done (timestamp)`), never a lone `✔`.
+
+### Working on tasks
+
+- **Task with subtasks** (a task that has indented children): create the branch with `npm run create:branch -- <prefix>/<desc>`, inferring the prefix from the task content (`feature/…` / `fix/…` / `chore/…`) — do not hand-write `git switch -c`, the command enforces the clean-tree / current-`main` / green-baseline precondition. Work on each subtask with commits, then present a concise handover for the user to review. Use this fixed shape:
+
+    ```md
+    ## Handover — <branch>
+
+    **Implemented:** <what was built, and how>
+    **Judgement calls:** <where the task was unclear, and what you assumed>
+    **Known problems:** <open issues, caveats, follow-ups>
+    ```
+
+    Once the user has no further objections, merge back: `npm run create:finish` (on the branch — it merges `--no-ff`, runs `npm run verify`, and deletes the branch). The branching model is documented in [CONTRIBUTING.md § Branching model](./CONTRIBUTING.md#branching-model).
+
+- **Leaf task** (no indented children): implement on the current branch and commit.
+
+In both cases, follow [CONTRIBUTING.md § Testing discipline (type-driven)](./CONTRIBUTING.md#testing-discipline-type-driven). Each subtask gets one or more commits.

+- **A new `npm run` script must reuse an existing prefix** (`create:` / `check:` / `fix:` / `test:` / `watch:` / `maintain:` / `publish:` / `setup:`). If none fits, that's a signal the script doesn't belong in the pipeline — not a reason to invent a new prefix. If it genuinely does belong, add the prefix to both lists here in the same commit; an undocumented prefix becomes invisible and quietly accrues members. (see [Script prefix convention](#script-prefix-convention))
 - **`oxlint-disable` directives live in source, not `.oxlintrc.json`.** The trade-off must sit next to the code it silences. This is a _human_ last-resort convention; agents must not add these — see [AGENTS.md § Never do](./AGENTS.md#never-do). (rationale: README § Tooling decisions)
 - **Don't put slow / network / whole-project scans in `check` or pre-commit.** Advisory scans are not correctness gates; they belong under `maintain:`. (see [Feedback tiers](#feedback-tiers) and [Script prefix convention](#script-prefix-convention))
+- **New work starts with `npm run create:branch`, never a hand-written `git switch -c`/`git checkout -b`.** The command carries the branch precondition; branching around it skips the clean-tree, current-`main` and green-baseline checks, and the skip is invisible until a failure can no longer be attributed. (see [Branching model](#branching-model))
+- **Work is merged back with `npm run create:finish`, never a hand-written `git merge`.** The command carries the merge-side preconditions (clean tree, current `main`, a `feature/`/`fix/`/`chore/` branch) and runs `npm run verify` after the merge, so a merge cannot land unverified.

+## Editor configuration
+
+`.editorconfig` is for editor compatibility, not a gate — it is a sane fallback for the files oxfmt does not format (shell scripts, dotfiles, `LICENSE`, the commit-message template, and git's `COMMIT_EDITMSG` buffer). Where both apply, `.oxfmtrc.json` is authoritative: oxfmt is the formatter, and the overlapping `.editorconfig` keys only keep non-oxfmt editors close to the formatted result.

 Script names in `package.json` use a prefix that signals _when_ the script is intended to run. A `<prefix>:<name>` script is implicitly aggregated by a `<prefix>` script (if one exists) and run by the corresponding lefthook hook or CI step. Picking the right prefix documents the script's intended lifecycle:
 
+- `create:*` — front doors of the repo's own workflow; these mutate git state rather than the source. `create:branch` opens a unit of work (asserts a clean tree, a current `main` and a green baseline before it branches), `create:finish` closes the branch half (merges the current unit of work into `main` and verifies the result), `create:release` closes the release half (maintainer-only). No bare `create` aggregator on purpose — see `publish:*` for the precedent.
 - `check:*` — read-only verification; never modifies files. Aggregated by `npm run check`.
 - `fix:*` — mutating counterpart of a `check:*` script. Aggregated by `npm run fix`; the diff is the review surface.
 - `test:*` — test scripts. `test` is the canonical entry point (`check:tsc` + unit tests); `test:unit` skips the typecheck for fast local iteration; `test:ci` adds c8 coverage.
 - `watch:*` — long-running watchers for the manual inner dev loop. Aggregated by `watch`; currently a single child (`watch:test`), and a future `watch:oxlint` / `watch:tsc` would run concurrently under that umbrella.
 - `maintain:*` — advisory repo-maintenance scans: read-only, but whole-project and/or network-bound, so never a correctness gate. Aggregated by `npm run maintain`.
 - `publish:*` — validates the _publishable artifact_ (e.g. `dist/`) rather than the source, so it needs a fresh build. (see [Rules the tools don't enforce](#rules-the-tools-dont-enforce) and [Publishing workflow](#publishing-workflow))
+- `setup:*` — one-time configuration of a fresh clone; mutates the local environment (git config, editor settings) rather than the repo source, so it is never part of a hook or CI step. Aggregated by `npm run setup` (the umbrella), run once after cloning.

+A new script should pick the prefix that matches its lifecycle, not invent a new one. If no existing prefix fits, that's a signal the script doesn't belong in the standard pipeline. When it genuinely does belong, a new prefix is allowed — but it enters both lists in this file in the same commit as its first member, otherwise the rule "reuse an existing prefix" silently develops an exception (the old `use:` prefix was exactly that; it is now retired into `setup:`).
 
-Separately, some top-level scripts are **bare** (no prefix): the entry points that either run a single tool (`build`, `clean`) or aggregate a `prefix:*` family (`check`, `fix`, `test`, `watch`, `maintain`), plus `verify` — a cross-cutting convenience composing `check` + `test:unit` into one whole-project correctness gate. It deliberately uses `test:unit` rather than `test` because `check` already runs `check:tsc`, so the type checker runs exactly once. Bare commands are how you invoke a tier; the `prefix:*` scripts are what those tiers are made of.

 This is why every test in the suite pairs an `expectTypeOf(...)` with an `assert.*` — keep them together. Type-first is also enforced structurally: `npm test` runs `check:tsc` before the test runner, so a wrong type can never be papered over by a passing assertion. Per [AGENTS.md § Never do](./AGENTS.md#never-do), reach green honestly — fix the types so both the type check and the runtime assertion pass, never suppress the ones you can't make pass.
 
+## Branching model
+
+**GitHub Flow (single-developer).** Every change — feature, fix, refactor — branches off `main` and is merged back via a local commit (no PR workflow on Gitea yet). Collaborative review via Gitea UI is not in place — Gitea is the lab; when something is tested and ready for production it will be promoted to GitHub.
+
+- **Base branch:** `main`
+- **Branch naming:** `feature/<desc>` / `fix/<desc>` / `chore/<desc>`
+- **Starting work:** `npm run create:branch -- <prefix>/<desc>`. It refuses, without changing anything, unless the working tree is clean (untracked files included), no merge/rebase/cherry-pick is in progress, `main` matches its upstream, and `npm run test` is green on `main` — so a later failure is always attributable to your edits. The prefix is still _your_ call, inferred from the task; the script validates it rather than guessing it.
+- **Merging:** `npm run create:finish` (on the branch). It asserts the same clean-tree / no-operation / current-`main` preconditions, fast-forwards a stale `main` (a true divergence is refused), merges the branch `--no-ff`, runs `npm run verify`, and deletes the branch only after the merge is green. The push is deliberately left to `create:release`, so the merge stays local and reviewable — read the diff yourself before finishing.
+- CI runs `npm run check` + `npm run test:ci` on every push to `main` — this is the authoritative gate. The one exception: a push headed by a release commit (`:rocket: Release x.y.z`) skips the full `build`/`maintain` jobs, because `create:release` pushes the tag for that exact commit right after and the tag run is the authoritative one (see `release-gate` in [.gitea/workflows/ci.yml](./.gitea/workflows/ci.yml)).
+- **Releases are NOT triggered by pushes.** Only the maintainer triggers a release (see [Publishing workflow](#publishing-workflow)).

 ## Publishing workflow

+Publishing is CI-only by policy. Local `npm publish` is not supported. The maintainer triggers releases from `main`:
 
-1. Develop and merge PRs to `main`.
+1. All intended changes are merged to `main` and passing CI.
-2. CI runs `npm run check` + `npm run test:ci` on every push and PR — this is the authoritative gate.
+2. The maintainer runs `npm run create:release`. VS Code opens `CHANGELOG.md` to finalize the `[Unreleased]` notes; because pubv refuses a dirty tree, any edit is committed first (then folded into the release commit), and pubv's interactive prompt suggests a version from those notes — the maintainer confirms or edits it.
-3. After all intended changes are on `main`, bump the version locally:
+3. `scripts/release.sh` creates a single release commit (graduated changelog + package.json bump, amended into one commit), tags it, and pushes everything to Gitea.
-    ```sh
+4. CI fires on both pushes: the `publish` job runs on the tag (`build` + publish-tier checks + release page + `npm publish`), while the branch run's `release-gate` job recognizes the release commit and skips `build`/`maintain` — the tag verifies the identical SHA, so no work is duplicated. The job graph lives in [.gitea/workflows/ci.yml](./.gitea/workflows/ci.yml) — keep that file, not this list, as the source of truth. The publish-tier checks must pass before the artifact is published. The `publish` job also creates the Gitea release page from the matching Keep-a-Changelog section (`scripts/release-notes.sh`); it runs _before_ `npm publish` so a broken page fails CI without consuming a version, and `npm publish` stays the last step.
-    npm version <patch|minor|major>
-    ```
-4. Push the tag to the forge (Gitea):
-    ```sh
-    git push --follow-tags origin main
-    ```
-5. The `publish` CI job runs on the tag: `build` → `publish:publint` → `publish:attw` → `npm publish --access public`. The publish-tier checks must pass before the artifact is published.

 The choice and configuration of each tool above is the result of deliberate trade-offs, not defaults. The non-obvious ones:
 
-- **`tsconfig.json` extends `@tsconfig/strictest` + `@tsconfig/node26`**; `tsconfig.build.json` extends it to add the emit-only options (`declaration`, `sourceMap`, `outDir`, `target: es2024`, `rewriteRelativeImportExtensions: true`) and to exclude test files. This separation lets the editor and CI type-check from one config while the build emits from the other.
+- **`tsconfig.json` extends `@tsconfig/strictest` + `@tsconfig/node26`**; `tsconfig.build.json` extends it to add the emit-only options (`declaration`, `sourceMap`, `inlineSources`, `outDir`, `target: es2024`, `rewriteRelativeImportExtensions: true`) and to exclude test files. `inlineSources` embeds the original TypeScript in `dist/*.js.map`, so debuggers can map into `src/` without it being shipped; `declarationMap` is intentionally off because a `.d.ts.map` cannot embed source and would dangle. This separation lets the editor and CI type-check from one config while the build emits from the other.
-- **Source imports use `.ts` extensions** so `node --strip-types` resolves them at test time. `rewriteRelativeImportExtensions: true` in `tsconfig.build.json` rewrites them to `.js` in the emitted `dist/*` output, so consumers see conventional ESM imports.
+- **`npm run build` first runs a `prebuild` hook that empties `dist/`.** `tsc` does not prune orphaned emit output — dropping `declarationMap`, for example, left stale `*.d.ts.map` files behind — so the build must start from an empty `dist/` to be reproducible. `prebuild` removes only `dist`; the manual `clean` still resets `dist` + `coverage`, so a local coverage report survives a build.
+- **Source imports use `.ts` extensions** so `node --strip-types` resolves them at test time. `rewriteRelativeImportExtensions: true` in `tsconfig.build.json` rewrites them to `.js` in the emitted JavaScript; the emitted `.d.ts` keep the `.ts` specifier, which TypeScript >= 5.0 resolves (see [Requirements](#requirements)), so no post-processing step is needed.
 - **Type-aware oxlint is enabled declaratively** via `options.typeAware: true` in `.oxlintrc.json` (powered by `oxlint-tsgolint`). The script commands stay clean — no CLI flag — and type-aware mode is a property of the config, not the invocation.
 - **Source-level `oxlint-disable` directives** are used for known type-aware false positives (see `src/pattern.ts`, `src/match.ts`, `src/index.test.ts`). The disable lives next to the code it silences, not in `.oxlintrc.json`, so the trade-off is visible to anyone reading the source.
 - **`knip --include dependencies,exports,files`** intentionally omits the `types` category, which produces systematic false positives for libraries whose exported types are part of the public API. The targeted scope keeps the signal high without config-file boilerplate.

 - **`check:tsc` runs first** in the `npm run check` chain so a type error short-circuits the rest (faster feedback than letting oxlint/oxfmt run and then failing on tsc at the end).
 - **The pre-commit hook sets the `LEFTHOOK_FILES` env var** to the staged-files list, and the affected scripts use `${LEFTHOOK_FILES:-<default>}` to default to the whole project when invoked manually. This keeps `package.json#scripts` as the single source of truth for the underlying commands — `lefthook.yml` only describes _what to run on which files_.
 - **`tslib` and `type-fest` are deliberately not used.** `tslib` is a runtime helper for old ES3/ES5 targets (the project targets ES2024); `type-fest` was never imported. knip caught both.
+- **`@spences10/pi-lsp` is pinned to `0.0.46` and is read-only by design.** The package inspects `node_modules/typescript`, sees major ≥ 7 with no `lib/tsserver.js` (true of the `typescript-go` / `tsgo` port), and spawns the repo's own `tsc --lsp --stdio` binary — no `typescript-language-server` dependency is required. Earlier releases (`≤ 0.0.10`) hard-wire to `typescript-language-server --stdio` and are TS6-only. The tool is _intermediate_ agent feedback (hover, references, definition, symbols, diagnostics); it has no rename / code-action / apply-edit surface, and never a correctness gate — `npm run check` / `verify` remain that. `.pi/settings.json` is the shared, committed declaration; `.pi/npm/` is a gitignored install cache that pi recreates automatically on a trusted startup (it runs `npm install` for any missing project package), so the cache is deliberately not tracked.
 
 ### Requirements
 
 - Node.js >= 26 (engines field; pinned via `.node-version`).
+- TypeScript >= 5.0 to consume the published declarations. The emitted `.d.ts` use `const` type parameters (TS 5.0) and keep their relative `.ts` specifiers; both resolve on TS >= 5.0 in `node10`/`node16`/`nodenext`/`bundler`.

+# Branch front-door. Run as `npm run create:branch -- <prefix>/<desc>`.
+#
+# How we got here (short): the branching model says every change starts from a
+# clean, current `main`, and the type-driven loop only produces trustworthy
+# results if the baseline was green *before* the first edit. Both facts were
+# prose. Prose rots silently — a rule nobody checks is a suggestion — so the
+# precondition became this script: it asserts, then branches, and the branch
+# only appears if the assertions passed. Cheap checks run first, `npm run test`
+# runs last: the expensive gate is not paid on a tree that was never eligible.
+#
+# Rejected for the prefix name: `run:` / `perform:` (both mean only "do the
+# thing named after them", so every script in the repo would fit under them and
+# the taxonomy collapses); `git:` (names the tool, not the lifecycle moment, and
+# advertises passthrough aliases); `start:` (describes this half, not the
+# release); `cut:` (idiomatic for both, but it needs VCS slang to decode, and a
+# signpost that has to be explained is not one); `flow:` (overloaded in a library
+# about type-level matching); and the existing families — `check:*` is read-only
+# and aggregated by `check`, so CI would run a command that mutates repo state;
+# `fix:*`'s review surface is a file diff, not a branch; `maintain:*` is advisory
+# and explicitly never a gate.
+#
+# `create:` was kept because both members really do create something: a branch,
+# a release. It was added to both prefix lists in CONTRIBUTING.md in the same
+# commit as its first members, because a prefix missing from those lists is
+# invisible — which was the `use:` mistake this repo carried in backlog.tasks (since retired into `setup:`).
+# There is deliberately no bare `create` aggregator: "run all the workflows"
+# describes nothing anyone wants, and `publish:*` already sets the precedent for
+# a prefix without one.
+#
+# Also rejected here: reusing `pubv`'s preflight (release-shaped, third-party,
+# and it would make branch start pay a build + pack it has no use for). The
+# merge half was originally rejected too ("review the diff yourself" is
+# judgment), but it now has its own front door — `create:finish` — which owns
+# the merge-side preconditions and the post-merge `verify`, so the start half
+# does not have to carry that burden.
+#
+# Every refusal is non-mutating except the baseline test, which runs on `main`
+# after we switch there — so a red `main` restores the branch you started on

+# Why this exists: `create:branch` opens a unit of work, but the close half
+# (`git checkout main && git merge --no-ff <branch>`) stayed prose in the
+# branching model, so it drifted per contributor and per session. This is the
+# mirror image of `create:branch`: it asserts the same preconditions (clean
+# tree, no in-progress operation, `main` matching its upstream), merges the
+# current `feature/`/`fix/`/`chore/` branch into `main`, proves the result with
+# `npm run verify`, and only then deletes the branch.
+#
+# `create:branch`'s comment argued against wrapping the merge as "judgment —
+# review the diff yourself". That judgment still lives here, just moved: the
+# maintainer reviews the handover *before* invoking this, and the script only
+# commits the merge, never the push. The push is owned by `create:release`, so
+# the release commit and its tag leave together and a local merge stays
+# reviewable (and can be reverted with `git revert -m 1`) until then. `--no-ff`
+# keeps the unit of work visible in `git log`.
+#
+# Unlike `create:branch` a stale `main` is fast-forwarded instead of refused:
