Tom Boucher 80de48c319 enhance(#3914): every phase records a truthful guard ledger (#4018)
* fix(#3914): retire n/no-process-exit where its successor governs

Epic #3889 criterion 5 — no phase closes with a guard added and its
predecessor left standing — is violated in the tree by the epic that wrote it.

local/require-registered-exit was registered on gsd-core/bin/**/*.cjs and
scripts/**/*.cjs, while n/no-process-exit stayed 'error' over a nine-glob block
covering those same two. Only the hooks 'off' exemption ever came down; the
predecessor's registration never did. Both rules have been enforcing the same
property on the same surfaces since P6.

Narrowed, not deleted. Seven of those nine globs have NO successor —
eslint-rules/, bin/lib/, pi/, examples/, vscode/, .kilo/, .opencode/ — so
deleting the rule outright would silently drop enforcement on all seven. That
is the inversion this epic has already hit three times: removing a coarse guard
because a narrower one exists somewhere it does not reach. Flat config is
last-match-wins and both successor blocks come after the nine-glob block, so
'n/no-process-exit': 'off' in exactly those two retires the predecessor
precisely where the successor governs and nowhere else.

The successor is strictly more precise: it permits process.exit only inside
terminateNow in cli-exit.cts, the single sanctioned terminator (ADR-3889 §3),
where n/no-process-exit permits none and would flag terminateNow's own
generated copy.

Asserted at the consumer's altitude via ESLint.calculateConfigForFile on real
paths, with the positive control that matters: n/no-process-exit is still
'error' on six of the seven successor-less globs, so a future edit that turns
this into a blanket disable goes red. bin/lib/ has no file in this checkout and
is reported as untested rather than given an invented path. Severity is
normalized across the string/numeric/array forms the API can return, and the
normalized value asserted — not truthiness.

Verified by running calculateConfigForFile myself on both superseded globs and
four controls before trusting the test.

Found and fixed inline: the change made an eslint-disable directive at
gsd-tools.cjs:257 partially unused, which --max-warnings 0 rejects; narrowed to
the one rule still in force.

Verification runs on the remote runner.

* docs(#3914): the epic added three guards, it did not remove one

The audit reconciled the epic ledger against what actually landed. The net is
+3, not -1: four lint:generated-sync --check arms (gen-scripts-cli-exit,
gen-hooks-cli-exit, gen-exit-code-registry, gen-exit-code-docs) plus one rule,
against two retirements.

An epic whose thesis was consolidation ended with a larger guard surface than
it started with. The additions are each defensible; the claim that the total
fell was never true.

Two of the three prior errors in this amendment are mine. It said "Net -1 by
count" above terms reading -1 -1 +1 +1 +1, which sums to +1 — an arithmetic
error in the paragraph directly below the sentence arguing that an ADR about
honest accounting must not pad its own ledger. And the term list omitted two of
the four --check arms, which is what turns that +1 into the real +3.

Recorded rather than quietly rewritten. This ledger has now been wrong three
times — the original -2, the -1 that replaced it, and #3914's own table, which
states -1 above terms summing to 0 — and a written claim nobody checked against
the thing it describes is the exact failure this epic exists to close.

Refs #3914

* fix(#3914): make the successor actually supersede before retiring the predecessor

An isolated security review found that the previous commit turned off a guard
that was still doing work. Reproduced by executing both rules against a
fixture, not inferred:

  const exit = 'exit';
  process[exit](1);

n/no-process-exit flags it; local/require-registered-exit did not, because it
early-returned on callee.computed. So retiring the predecessor on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs un-guarded that shape on precisely
the two globs this epic's exit contract cares most about.

This is the third time in this epic I have removed a coarse guard on the claim
that a narrower one covered it, without checking construct-level parity — after
the allowlist key-to-prefix-to-exact-membership sequence and the band
ranges-to-categories one. The rule is the same every time: a narrower guard
supersedes a coarser one only where it demonstrably reaches at least as far,
and "demonstrably" means executing both against the constructs, not reading
either.

The successor now resolves computed property access for the statically
determinable cases — a string Literal, and an Identifier bound once to a string
Literal, resolved through scope — and leaves genuinely dynamic properties
alone so the rule does not over-fire. Measured after the fix: plain
process.exit flagged, process['exit']() flagged, process[exit]() flagged,
process[globalThis.k]() not flagged. That makes it a strict superset of the
predecessor on these globs, since process['exit']() was caught by NEITHER rule
before.

The second finding is worse than the first, because it was reasoning rather
than oversight. My justification comment claimed n/no-process-exit "would flag
terminateNow's own generated copy here". It would not — that file is in the
global ignore list, so neither rule ever lints it. There was no conflict to
resolve; I wrote a rationale I had not checked, in a change whose entire
subject is written claims nobody verified. Both comment blocks now state the
real basis.

The tests that should have caught this asserted only rule SEVERITY per glob and
never construct REACH, which is exactly how a coverage hole passed. A parity
matrix now pins all five shapes, including a RED/GREEN regression pin against
an inlined reproduction of the pre-fix rule — inlined rather than loaded from
HEAD, because HEAD resolves to the fixed commit under the remote runner and
would silently stop testing anything.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the two exit rules are complementary — keep both

Reverts this branch's retirement of n/no-process-exit. The premise was wrong
twice, and the second review proved the change itself was wrong.

I claimed local/require-registered-exit was a strict superset on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs. Measured, successor vs predecessor:

  function f(exit) { process[exit](1); }         0  vs  1
  let exit='exit'; exit='exit'; process[exit]()   0  vs  1
  const { exit } = ...; process[exit](1)         0  vs  1

plus for-of bindings, let-then-assign, var redeclaration, catch params, and an
undeclared global named exit. The predecessor matches any identifier NAMED
exit however it is bound; the successor resolves only a string literal or a
single-write const. It never was a superset — I asserted the relationship after
fixing one construct and did not re-check the rest.

The justification was independently false: all three generated cli-exit copies
are in the global ignore list, so n/no-process-exit was never flagging
terminateNow. There was no conflict to resolve. I wrote a rationale I had not
verified, in the phase whose subject is written claims nobody checked.

So criterion 5 does not apply to this pair. They are not predecessor and
successor — they are complementary, each catching constructs the other misses.
The epic's criterion assumed a replacement relationship that does not exist
here, and retiring either rule loses real coverage. The ADR ledger now says so
with the measured shapes.

What survives is the genuine improvement: the computed-property strengthening.
local/require-registered-exit now catches process['exit'](1) and optional-chain
terminators like process?.[k]?.(1), which NEITHER rule caught before, while
correctly ignoring a genuinely dynamic property so it does not over-fire.

The parity tests are rewritten to assert what is true rather than what I wanted
to be true: a bidirectional matrix where each rule is shown catching shapes the
other misses. The previous matrix tested only the four shapes where the
successor wins, which is precisely why the regression shipped — a test set
selected to confirm the thesis.

Also corrected: a stale ADR sentence claiming a third wrong ledger version that
does not exist (the table it described now reads +3 over terms summing to +3),
and a changeset whose stated motivation was the false generated-copy conflict.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the exemption term was a no-op — the net is +4

Fourth correction to this ledger, and a fourth error of the same kind.

Every version counted removing the n/no-process-exit 'off' entry from the hooks
block as -1. Measured: calculateConfigForFile returns undefined for that rule on
hooks/**. It was never registered there, and no broader block sets it globally,
so the 'off' entry overrode nothing and removing it changed no enforcement at
all. A no-op removal, not a guard removal — the same category error as counting
baseline acknowledgement entries: a thing that is not a guard, in guard units.
It is misattributed too; that block came down in d98b55562 (#3910), already on
next before this branch existed.

So the epic added FOUR guards, not three.

This surfaced from a test of mine that overclaimed. I asserted n/no-process-exit
was error on "all nine CommonJS/hook globs" — but hooks is not one of the nine,
and the rule resolves to undefined there. Fixing the test to match reality is
what exposed the ledger term, which is the argument for tests that assert
identity rather than a comfortable shape.

The hooks state is now pinned explicitly rather than glossed: n/no-process-exit
unregistered, local/require-registered-exit error. It is mildly surprising and
therefore worth a test.

Also updates a pre-existing test that documented the old name-based-only
boundary as intentional. The computed-property strengthening deliberately moves
that boundary — process['exit'](0) was caught by NEITHER rule before — so the
test now asserts the new contract and cites the ADR, rather than being left to
fail or the rule weakened to satisfy it. A contract change should read as
deliberate in the test that pins it.

Verification runs on the remote runner.

Architecture Decision Records

This directory contains Architecture Decision Records (ADRs) for GSD.

Each ADR documents one architectural decision: what was decided, why, and what consequences follow. ADRs are append-only. Amendments extend existing ADRs with a dated section rather than replacing them.

Reading this corpus

Start with the index below, and respect the status. The index is grouped so that the first table — Active decisions — is the set that governs the system as it stands. An ADR in Superseded, Retired, and Legacy is historical: it records what was once decided and names what replaced it. Do not cite it as current architecture.

Two things the index makes explicit, because getting them wrong has actually misled readers here:

  • "Read first" on an active ADR points at a broader ADR that now frames it. A decision can be entirely correct and still not be the whole picture. The runtime capability descriptor (ADR-1016) is live and load-bearing, but ADR-1239 (EoS — GSD as an Embeddable Orchestration Engine) subsumes it as the declarative adapter and inverts its direction: GSD is the engine a host embeds, not an installer that projects onto a host. For how GSD meets a host, EoS is the current frame.
  • Proposed means not ratified — and it is kept honest. On 2026-07-17 the corpus was audited against the shipped tree and nine ADRs whose decisions had demonstrably shipped were ratified to Accepted, each carrying a dated Ratification section with the evidence (see ADR-857 for the fullest example). The ADRs that remain Proposed are Proposed for a reason recorded in the file — an unmet acceptance criterion, an outstanding phase, or a successor ADR already planned — not through neglect. Trust the label; if you think it is wrong, prove it in a dated section and see Ratifying a stale Proposed.

Naming Convention

New ADRs use issue#-prefix slug naming:

docs/adr/<issue#>-<kebab-slug>.md

Examples: 2264-golden-parity-redesign.md, 1239-gsd-embeddable-orchestration-engine.md.

Why

Two developers computing "next ADR number" locally against main will independently pick the same integer and both ship. The collision is already on disk — 0010-* exists twice and 0011-* exists three times. GitHub issue numbers are server-assigned and atomic: the moment you open an issue, that number is reserved globally. Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — two PRs that each use a distinct issue# as their ADR prefix never collide. Same shape, same solution.

Legacy naming is not Legacy status

Files 0001-* through 0012-* are preserved as immutable historical record of the old local-compute numbering. The duplicate 0010-* and the three-way 0011-* are documented residue of that convention — not patterns to imitate. Do not renumber them.

This is the single authoritative statement of the legacy range. docs/contributor-standards.md references it rather than restating it, so the two cannot drift.

Two other zero-padded files look legacy but are not: 0174-retire-gsd-sdk-package-boundary.md (issue #174) and 0656-research-module-seam.md (issue #656) are mis-padded modern ADRs — modern, issue-numbered files whose four-digit padding is a mistake. They are NOT part of the legacy sequential set above and are not "old local-compute numbering" residue.

This is a statement about filenames only. Many of those ADRs are Accepted and load-bearing today (ADR-0002, ADR-0004, ADR-0008, ADR-0009). An old filename says nothing about whether a decision still holds. The Legacy status in the table below is a separate claim — see the vocabulary.

Because 0010-* and 0011-* each resolve to more than one file, a bare cross-reference like "ADR-0011" is genuinely ambiguous. Link the file (see Lifecycle rules).

Full process

See CONTRIBUTING.md — "Proposing an ADR or PRD" for the end-to-end workflow: opening the issue, waiting for approval, naming the file, and submitting the PR.

PRDs live in docs/prd/, not here. (0011-review-default-reviewers-prd.md predates that directory and is kept in place as frozen historical record.)

Lifecycle rules

These are enforced by scripts/gen-adr-index.cjs, which runs in CI via npm run lint:generated-sync. A violation fails the build with the exact file and fix.

1. Every ADR declares one status from the canonical vocabulary

The first word of the Status field must be one of:

Status Means Obligation
Accepted Decided and in force. Cite it. —
Proposed Decided in principle, not ratified. Do not cite as settled. If the work has demonstrably shipped, ratify it (below) — do not leave the label lying.
Superseded A specific newer ADR replaced this decision. Must name the successor as a file link.
Retired What this ADR decided no longer exists at all, and no single ADR replaced it. Say what was removed and when.
Legacy Frozen historical record, kept for provenance; not a pattern to follow. Say why it is frozen.

Prose may follow the token (Superseded by [ADR-0174](0174-retire-gsd-sdk-package-boundary.md) (2026-05-23); originally Accepted (2026-05-09)). Both the bullet form (- **Status:** Accepted) and the table form (| **Status** | Accepted |) are accepted.

Write [ADR-0011](0011-skill-surface-budget-module.md), not ADR-0011. Bare ids are ambiguous for 0010/0011, and unlinked references cannot be checked.

If you mean an issue, write #857 — not ADR-857. (An ADR and its owning issue often share a number; that is intentional and not a conflict.)

3. Supersession and subsumption are symmetric

These are different relations. Do not conflate them:

  • Supersedes / Superseded by — the target is replaced. Its status becomes Superseded.
  • Subsumes / Subsumed by — the target still holds, but a broader ADR now frames it. Its status is unchanged; it becomes a component of the larger decision.

If A declares either relation toward B, B must record the reciprocal. A one-way pointer is the failure this corpus actually suffered: ADR-1239 declared it subsumed four ADRs, none of which said so, and none of which pointed back — so a reader landing on any of them concluded the superseded frame was the way forward.

Only an Accepted ADR is owed the back-link. A Proposed ADR's claim is prospective: it has not taken effect, so its target is not marked. On ratification, the check begins demanding the back-links.

4. The declared id matches the filename

An H1 of # ADR-0175: … in a file named 218-*.md is a rename that never finished. The id in the title must match the filename's prefix.

5. A trailing H1 status bracket must agree with the Status field

Many ADRs restate their status in the H1 — # ADR-1610: … [Accepted]. That bracket is the first thing a reader sees, and the index strips it when rendering the title, so a stale one used to be invisible to everyone but the reader it misled.

If the H1 ends in a bracket holding a status token, it must name the same status as the Status field. Comparison is case-insensitive and against the parsed token, so [Superseded] agrees with Status: Superseded by [ADR-0174](0174-retire-gsd-sdk-package-boundary.md) (2026-05-23).

A trailing bracket that is not a status token — [Draft], [WIP] — is treated as part of the title and left alone. If you want a bracket the gate ignores, do not spell it like a status.

A link whose target does not exist on disk fails the check, naming the file, the line, and the unresolved target. This covers every markdown file in this directory, including this README and any file whose name breaks the convention above.

Written as Treated as
[t](900-beta.md), [t](../prd/) resolved — a directory counts
[t](900-beta.md#section) the file is resolved; the #fragment is not checked
[t](https://…), [t](mailto:…), [t](//host/x) out of scope — absolute destinations are never fetched
[t](#lifecycle-rules) out of scope — a same-document anchor is not a file reference
[t](/docs/adr/x.md) resolved against the repository root, as GitHub does
a link inside a ``` fence or `backticks` not a link — markdown does not render one there, so it is never resolved
[text][ref] reference-style, <a href>, bare autolinks not supported; write an inline link

Two consequences worth stating outright:

  • Case matters, on every platform. [t](0001-Alpha.md) pointing at 0001-alpha.md fails even on macOS and Windows, because it 404s on github.com and reds the Linux CI lane. The failure names the entry it found so the fix is obvious.
  • A link to a generated or ignored path fails. Nothing here consults .gitignore; the question is only whether a reader following the link lands somewhere. Cite the hand-authored source rather than the build artifact.

If the gate rejects something you wrote

Reproduce it locally first — it is the same command CI runs, and it names the file, the line, and the target:

node scripts/gen-adr-index.cjs --check

Then work from the reason:

What it says What to do
does not resolve — no such file or directory at … Fix the path. It is relative to docs/adr/, so a sibling ADR is just 900-slug.md. If the target genuinely does not exist yet, drop the link rather than leaving it pointing nowhere.
…Did you mean X? — link targets are case-sensitive on github.com Match the on-disk name exactly. Your machine may open the file regardless; github.com and the Linux CI lane will not.
escapes the repository The path resolves outside the repo. Link something inside it, or use an absolute URL — those are out of scope and never checked.
is a symlink that escapes the repository An ADR file itself is a symlink pointing outside the repo. Commit a real file.
H1 status bracket […] contradicts the Status field (…) Update whichever of the two is stale so they agree. The Status field is authoritative; the bracket is a restatement for the reader.

A link that is an example, not a destination, belongs in backticks. The gate skips fenced blocks and inline code entirely, because markdown does not render a link there. That is the escape hatch for illustrative syntax — the table above is written that way, which is why it does not fail this check. An indented code block (four spaces) is not skipped; use backticks.

To consume the result from a script rather than by eye, use --json (below) and branch on each violation's stable reason code.

Ratifying a stale Proposed

A stale Proposed is not cosmetic: it tells contributors and agents that live architecture is an unbuilt idea. Fix it — but on evidence, not vibes.

The bar. All four must hold before flipping to Accepted:

  1. The decided mechanism demonstrably exists in the tree — name the files, symbols, and tests.
  2. The owning issue is closed as completed. A closed issue is not proof: stateReason of not planned / duplicate means the decision was dropped (that is Legacy or Retired, not Accepted).
  3. No material part is unshipped. If the ADR defines phases and one is outstanding, or states its own bar for acceptance and that bar is unmet, it stays Proposed.
  4. No later ADR supersedes it, and no approved issue already plans its graduation as separate work.

The procedure. Set the status to Accepted — ratified <date> (originally Proposed <date>), add a dated ## Ratification section holding the evidence, then run node scripts/gen-adr-index.cjs --write. If the ADR claims to supersede or subsume others, the gate will now demand their back-links — that is the point. Ratify deliberately.

Two traps worth knowing, both hit during the 2026-07-17 audit:

  • Shipped code is necessary, not sufficient. Eight ADRs had every named module, symbol, and test present and their epics closed — and still failed the bar: ADR-2264's own headline acceptance criterion is unmet in the tree, ADR-230's decided branch protection does not match the live API, ADR-660's namesake mechanism is performed by hand, and ADR-959 has an approved issue planning its graduation as its own ADR. Verify the decision, not just the code.
  • "Supersedes" is often "subsumes". Read what the ADR means before the gate makes you act on what it says. ADR-857 said "Supersedes (generalizes)"; taken literally, ratifying it would have stamped two live seams (ADR-0011, ADR-58) as dead. The parenthetical was the truth; the field name was wrong.

Maintaining the index

The index is generated. Do not hand-edit it. Everything between the ADR-INDEX:START / ADR-INDEX:END markers is derived from the ADR files themselves:

node scripts/gen-adr-index.cjs            # print the index
node scripts/gen-adr-index.cjs --write    # regenerate it into this file
node scripts/gen-adr-index.cjs --check    # CI: fail if stale or invalid
node scripts/gen-adr-index.cjs --json     # same checks, machine-readable report

After adding an ADR, or changing any ADR's status or relations, run --write and commit the result. npm run lint:generated-sync runs --check in CI, so a missing or stale row fails the build rather than rotting silently.

--json runs the same validation as --check and writes a report to stdout instead of prose to stderr, with the same exit code. Each violation carries a stable reason code, so a tool consuming this never has to pattern-match an error message:

{
  "ok": false,
  "adrCount": 76,
  "indexStale": false,
  "violations": [
    { "file": "2704-example.md", "line": 41, "reason": "link_unresolved",
      "target": "reference/x.md", "resolved": "docs/adr/reference/x.md" }
  ]
}

An unrecognized flag is rejected rather than ignored.

This replaces a hand-maintained table that had drifted to 40 of 65 ADRs — the entire capability family and EoS itself were missing from it, which is precisely why the ADRs a reader most needed were the ones they could not find.

Seam map

Orientation for the module-ownership ADRs. This section is prose and hand-maintained; the index above is the authority on status.

How GSD meets a host — start at ADR-1239 (EoS). It is the current frame and subsumes the descriptor/projection ADRs (ADR-1016, ADR-58, ADR-3660, ADR-894) as adapters beneath it.

The SDK seam map is gone. ADR-0005 was once the entry point for SDK module ownership; it is superseded by ADR-0174, which retired the @opengsd/gsd-sdk package boundary entirely. There is no sdk/ tree. Read ADR-0174 for the single-runtime collapse; the seam-Module vocabulary survives under one src/.

ADR-0006 documents how query handlers project planning paths (cwd → effectiveRoot → .planning/<project>/...). Cross-reference the Planning Workspace Module (ADR-0004) for workstream pointer policy.

ADR-0008 documents the Installer Migration Module for safe install-time moves, removals, config rewrites, and user-data preservation.

ADR-0009 documents the Shell Command Projection Module seam for runtime-aware projection of installer-owned command text and projection IR. Its Phases 3–4 absorbed the File Operation Engine Module (ADR-0010).

ADR-0011 documents the Skill Surface Budget Module for install-time skill/agent profile staging (--profile=<name>, .gsd-profile marker, requires: closure) and the Phase 2 runtime /gsd:surface command.

ADR-1411 establishes the Resolution Provenance principle: context resolution (config loading, project-root anchoring, workstream resolution) must report its provenance rather than fall open silently to defaults. It is the resolution-side analog of ADR-227 (input-validation shape).
