feat(scripts): generate the RFC index tables from the tree

Browse Source 
docs/rfc/README.md's per-lifecycle tables are now generated between
gen-rfc-index marker comments from each RFC's path (lifecycle/class),
H1 title (optional 'RFC: ' prefix stripped), and filename date, sorted
by date then filename — the one docs region every proposal wave edits
and every concurrent branch conflicts on becomes derived state.

scripts/rfc-index.ts owns the shared walker (closed lifecycle/class
sets, structure rules, parseable-H1 requirement) and the renderer;
gen-rfc-index.ts is the writer CLI; verify-rfc-classification.ts keeps
the structure check and asserts the committed regions byte-match a
fresh render (freshness subsumes the index-completeness check, since a
generated-from-disk table is definitionally complete and correctly
headed). A malformed H1 is a hard error in both directions, so the H1
is now load-bearing as the title source — the one nonconforming H1
(a status suffix duplicating the path) is normalized.

Implements docs/rfc/implemented/process/2026-07-04-generate-rfc-index-tables.md
(moved from proposed/ and amended to the shipped mechanics); the
classification RFC's verify-only stance carries the supersession
cross-link per implemented/AGENTS.md.

## Classification
Each RFC is filed under exactly one **class** — the kind of decision it records. The class is encoded in the path (the folder *is* the label, so a file's location declares its class) and the set is **closed**: `scripts/verify-rfc-classification.ts` rejects any folder outside the set and asserts this index lists every RFC under the heading matching its path. Adding a new class means amending that gate and this section, not just dropping a new folder. See [the classification RFC](implemented/process/2026-06-20-rfc-classification.md) for why the taxonomy is path-encoded and gated.
Each RFC is filed under exactly one **class** — the kind of decision it records. The class is encoded in the path (the folder *is* the label, so a file's location declares its class) and the set is **closed**: `scripts/rfc-index.ts` owns the canonical set, `scripts/verify-rfc-classification.ts` rejects any folder outside it, and the index tables below are **generated** from the tree (`pnpm run gen-rfc-index` rewrites the marker-delimited regions from each RFC's path, H1 title, and filename date; the gate fails when they are stale). Adding a new class means amending that `const` and this section, not just dropping a new folder. See [the classification RFC](implemented/process/2026-06-20-rfc-classification.md) for why the taxonomy is path-encoded and gated, and [the index-generation RFC](implemented/process/2026-07-04-generate-rfc-index-tables.md) for why the tables are generated while this prose stays curated.

It asserts every file under a lifecycle folder lives in a class folder from the canonical set (a loose `.md` at a lifecycle root, or an unknown class folder, fails), and that `README.md` lists every RFC exactly once under the `###` heading matching its `{lifecycle}/{class}` path. The canonical class set lives as a `const` in this script — the machine source of truth — and [the index](../../README.md) documents it in prose; the two are kept in sync by hand (the README's completeness is gated, its class *descriptions* are not). This mirrors `verify-event-taxonomy`, which checks a doc table against source.
- **`scripts/verify-rfc-classification.ts`** — the closed set and index freshness. It asserts every file under a lifecycle folder lives in a class folder from the canonical set (a loose `.md` at a lifecycle root, or an unknown class folder, fails), and that the README's marker-delimited index regions byte-match a fresh render from the tree (see [generate the RFC index tables](2026-07-04-generate-rfc-index-tables.md)). The canonical class set lives as a `const` in `scripts/rfc-index.ts` — the machine source of truth shared with the generator — and [the index](../../README.md) documents it in prose; the README's class *descriptions* stay hand-written, its tables are generated.
- **`scripts/verify-doc-refs.ts`** — source comments that cite docs. RFC paths are referenced not only from Markdown but from TypeScript doc comments (root-relative prose like `docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md`). `verify-md-links` never saw those, so the reorg could have silently orphaned them. This gate scans repo-authored `.ts` under `packages/**` and `examples/**` (excluding built `lib/` and `vendor/`) for `docs/….md` tokens, resolves each root-relative, and asserts it exists. It requires the `.md` extension so extensionless prose (`docs/postmortem/0001`, `docs/architecture.md § plugin checklist`) is left alone.
### Rejected alternatives
- **A `Classification:` prose line** in each file (next to `Status:`), parsed by the gate. Workable, but it duplicates into the file a fact the path can already carry, and a line can disagree with its folder. Path-encoding makes the label and its storage the same thing — there is nothing to keep in sync.
- **A `refactor` class.** It overlaps `simplification` almost entirely; the only discriminator anyone reached for was "does observable behavior change?", which `simplification` already encodes (it does not). One class, not two.
- **Auto-generating the README index** from the filesystem. Rejected to keep the index hand-written like every other doc here; the completeness gate gives the same drift-protection without generated Markdown in a curated file.
- **Auto-generating the README index** from the filesystem. Rejected here to keep the index hand-written; superseded by [generate the RFC index tables](2026-07-04-generate-rfc-index-tables.md) once stacked proposal waves made the hand-written tables the repo's most conflict-prone docs region — the tables are now generated between markers while the surrounding prose stays curated.
## Consequences
- Every RFC now sits under a class folder, and the index groups by class within each lifecycle. A reader scans one heading to see all simplifications, or all testing decisions.
- Two more fast tsx scripts in the `doc-sync` chain; no new dependency (the mdast/GFM stack was already present for `verify-md-wrap`/`verify-md-links`).
- Adding a class is a deliberate act: amend the `const` in `verify-rfc-classification.ts` and the [Classification section](../../README.md#classification), not just `mkdir` a folder. The gate rejects an unknown folder, so an ad-hoc class can't slip in.
- Adding a class is a deliberate act: amend the `const` in `scripts/rfc-index.ts` and the [Classification section](../../README.md#classification), not just `mkdir` a folder. The gate rejects an unknown folder, so an ad-hoc class can't slip in.
- Source-comment doc references are now gated too — a moved or renamed doc that a `.ts` comment cites fails the pre-push hook, closing a drift class `verify-md-links` structurally could not see.

# RFC: Generate the RFC index tables
Status: implemented
## Problem
`docs/rfc/README.md`'s per-lifecycle/per-class tables list facts that are fully derivable: an RFC's path encodes lifecycle and class, its filename encodes the first-proposed date, and its H1 carries the title. A hand-maintained copy of those facts is also the repo's highest-contention docs hotspot: every proposal wave appends rows to the same few lines, so concurrent RFC branches conflict precisely there while agreeing everywhere else, and each conflict is resolved by hand-merging rows whose content the filesystem already knows. [The classification RFC](2026-06-20-rfc-classification.md) originally kept the index hand-written for curation's sake — but the curated part of the README is the prose, and the prose never conflicts; only the mechanical tables do.
## Decision
Keep the curated prose; generate the tables. [`scripts/rfc-index.ts`](../../../../scripts/rfc-index.ts) is the shared source of truth — the tree walker (owning the closed lifecycle/class sets and the structure rules, including a parseable-H1 requirement) and the renderer (rows from H1 title with any `RFC: ` prefix stripped, plus the filename date, sorted by date then filename, grouped as `### {Class}` sections in canonical class order). Two thin consumers share it:
- [`scripts/gen-rfc-index.ts`](../../../../scripts/gen-rfc-index.ts) (`pnpm run gen-rfc-index`) rewrites the three marker-delimited regions in the README (`<!-- gen-rfc-index:begin {lifecycle} -->` … `end`), one per `## {Lifecycle}` section, leaving everything outside the markers untouched.
- [`scripts/verify-rfc-classification.ts`](../../../../scripts/verify-rfc-classification.ts) (a `doc-sync` member) checks structure and asserts the committed regions byte-match a fresh render — the `gen-cordis-catalog`/`verify-cordis-catalog` pattern. Freshness subsumes the index-completeness check: a generated-from-disk table is definitionally complete and correctly headed.
Adding, moving, or deleting an RFC means editing only the RFC file and running the generator; the classification RFC's rejected-alternatives record carries the supersession cross-link.
## Why not the verifier-only model?
It catches mistakes but still makes every proposal edit a shared hotspot, and a failed verifier is strictly more annoying than a generator for a purely mechanical row: the author has already named and placed the file; the index copy adds no information. This is the same hand-list-versus-derivation judgment the [package-inventory proposal](../../proposed/process/2026-06-20-discover-package-inventory.md) applies to tsconfig references and knip stanzas — applied to the one list that demonstrably conflicts.
## Consequences
- The generated regions are explicit: marker comments make script ownership obvious to reviewers, and the generator refuses to run on a structurally invalid tree.
- A malformed or missing H1 is a hard error in both the generator and the gate — the H1 is now load-bearing as the index title source.
- Concurrent RFC branches resolve index conflicts by rerunning the generator, never by hand-merging rows.

# RFC: Generate the RFC index tables
Status: proposed
## Problem
`docs/rfc/README.md`'s per-lifecycle/per-class tables are hand-maintained even though every fact in them is derivable: an RFC's path encodes lifecycle and class, its filename encodes the first-proposed date, and its H1 carries the title. `scripts/verify-rfc-classification.ts` already walks the tree and cross-checks the index — the expensive parsing exists; it reports instead of writing.
The tables are also the repo's highest-contention docs hotspot: every proposal wave appends rows to the same few lines, so concurrent RFC branches conflict precisely there while agreeing everywhere else, and each conflict is resolved by hand-merging rows whose content the filesystem already knows. [The classification RFC](../../implemented/process/2026-06-20-rfc-classification.md) records rejecting auto-generation to keep the file curated — but the curated part of the README is the prose, and the prose never conflicts; only the mechanical tables do.
## Proposal
Keep the curated prose; generate the tables. Add a `gen-rfc-index` mode (a `--write` flag on `verify-rfc-classification.ts`, or a sibling script sharing its walker) that scans the RFC tree, reads each H1, derives the date from the filename, and rewrites the table rows under stable generated markers per `## {Lifecycle}` / `### {Class}` section; `verify-rfc-classification` asserts freshness — the `gen-cordis-catalog`/`verify-cordis-catalog` pattern. The class and lifecycle sets stay closed in the script. The implementing PR amends the classification RFC's rejected-alternatives record per [implemented/AGENTS.md](../../implemented/AGENTS.md), since this supersedes that recorded choice.
## Why not keep the verifier-only model?
It catches mistakes but still makes every proposal edit a shared hotspot, and a failed verifier is strictly more annoying than a generator for a purely mechanical row: the author has already named and placed the file; the index copy adds no information. This is the same hand-list-versus-derivation judgment the [package-inventory proposal](2026-06-20-discover-package-inventory.md) applies to tsconfig references and knip stanzas — applied to the one list that demonstrably conflicts.
## Acceptance criteria
- `pnpm run gen-rfc-index` (or the chosen spelling) rewrites only the generated table regions; `verify-rfc-classification` fails when they are stale and passes after regeneration.
- Adding, moving, or deleting an RFC requires editing only the RFC file itself; the rows are produced from path + H1 + filename date.
- The prose outside the generated markers is untouched by the generator; `pnpm run doc-sync` passes.
## Risks
Generated regions inside a curated file need explicit markers so ownership is obvious to reviewers. Reading H1s makes a malformed header a generator error — useful pressure, and it should fail clearly. This supersedes an implemented process decision; amending that RFC's record is part of the change, not optional.
