* test(#4740): pin the per-step role-family partition Failing-first coverage for the Loop Host Contract role partition. At this commit crossCheckRoleFamilies does not exist, so the rows throw "crossCheckRoleFamilies is not a function" -- the RED proof they bind to behavior rather than restating it. ADR-894 section 3 assigns roles per step but parenthesises the assignment as "(illustrative roles)", and nothing enforced it. The only thing standing in the way was a single deepEqual in this same file, which is editable prose. Rows cover: each step's own family accepted; a strict subset accepted; a foreign role rejected at every step; an unknown role rejected; an unknown step failing CLOSED; capitalization not silently matched; every offending role reported rather than only the first; and purity, because buildContract puts the same array into the generated contract. Two rows exist because an earlier cut of this suite was vacuous. The purity fixture is deliberately UNSORTED -- an alphabetically-sorted fixture cannot fail an in-place sort(), and the mutant was being killed by three unrelated rows instead. A parity row asserts ROLE_FAMILY and ROLE_TO_AGENT cover the exact same role-name domain, both directions: they are parallel constants over one domain, so divergence is the generative-fix class CLAUDE.md names. Every negative row asserts the offending ROLE NAME and the STEP NAME appear in the message. A count-only assertion survives a mutant that reports the wrong role, which the 80% Stryker gate would surface only after a full CI round-trip. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#4740): reject a cross-family agent-role declaration Orchestration and execution are distinct functions of the loop and must not drift into one another. That partition was real but unenforced: ADR-894 section 3 calls its own role assignment "illustrative", and the generator accepted anything. Adding orchestrator to execute-phase.md's agent-roles line compiled, --check passed once regenerated, and capability-validator.cjs then began accepting into:"orchestrator" at every execute point. ROLE_FAMILY maps every role to one of orchestration, planning or execution. EXPECTED_FAMILY_BY_STEP gives each of the five steps exactly one family. crossCheckRoleFamilies rejects a cross-family role, a role outside the vocabulary, and an unknown step. It reports every offender, not the first. It fails CLOSED on an unknown step, deliberately diverging from assertPointsCoverage's "unknown step -- caught elsewhere". For points that is true: the canonical-set and duplicate checks catch it. For roles there is no second net, so failing open would leave an unknown step as the one input that bypasses the gate. crossCheckRoles' orchestrator exemption is untouched. ROLE_TO_AGENT maps roles to agent FILES and the orchestrator is the host, owning none -- admissibility and agent-file presence are separate concerns with separate checks. Additive to section 3's existing rule that contribution.into must be a member of the step's agentRoles, which is unchanged. That governs what a CAPABILITY may target; this governs what a WORKFLOW may declare. No capability is affected, and all five workflows already declare single-family sets, so the gate is green on the commit that introduces it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#4740): make the ADR-894 role assignment normative Section 3 parenthesises its per-step role assignment as "(illustrative roles)". That word was accurate about the list's PURPOSE -- it illustrated the shape of a generated contract entry -- and wrong about its STATUS, because the assignment was load-bearing from the moment the generator consumed it. Read literally it makes the partition an example rather than a rule. Appended as a dated in-place section per docs/contributor-standards.md, which records that an accepted ADR is never rewritten and names this the default pattern. Section 3's original body is untouched. The amendment states the three disjoint families, the one family each step admits, that a step may declare a strict subset but never outside it, and why this is a clarification rather than a new decision: the contract is generated from the workflow markers "so it cannot drift into a lie", and all five workflows have always declared single-family sets. What was absent was any statement that it is required, and any check that it holds. It also pins the distinction that is easy to re-merge: contribution.into being a member of agentRoles governs what a CAPABILITY may target and is unchanged; the family rule governs what a WORKFLOW may declare. The CONTEXT.md glossary entry for the Loop Host Contract records the same, beside the agent-reference drift guard it already documented.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#4740): backfill changeset pr number Replaces the pr:0 placeholder with 4742 now that the PR exists. Verified with GITHUB_BASE_REF=next, the way CI runs them: changeset lint and lint:docs both go from invalid_pr(0) to ok. Without that env both report success without evaluating the branch at all. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4740): stop injecting the orchestrator procedure into executors claude-orchestration declared a contribution at execute:wave:pre with into:"executor". loop-hook-dispatch.md defines a contribution as "inject fragment.inline verbatim into the context for the role named in into", so its 267 lines were injected into EXECUTOR prompts whenever the capability was enabled. Those lines are orchestration end to end -- construct a wave manifest, resolve the dispatch backend, invoke the Workflow tool to spawn executors, bridge per-agent results into the merge chain. An executor can act on none of it. Retargeting to into:"orchestrator" would not have been a fix. ROLE_TO_AGENT carries no orchestrator entry by design: the orchestrator IS the host, and the host's procedure lives in execute-phase.md. A step's agentRoles enumerates agents a capability may inject context INTO, so adding orchestrator there would model the host as an injectable agent -- the same category error pointed the other way, and it would need an exception carved into the partition the same issue just made normative. So the defect is the mechanism, not the label. A contribution injects into an agent's context; "replace step 3's inline dispatch loop" is a change to what the HOST does. The contribution channel was serving as a host-behaviour directive because it was the only channel available at an execute point. The entry is removed. plan:post into:"planner" is correct and untouched. The procedure is preserved verbatim at docs/workflow-backend-dispatch.md inside the capability -- it is the only copy in the repo -- and is no longer injected anywhere. Consequence, not softened: the Workflow backend now has no loop wiring. Detection, emission and config remain and the design is intact, but nothing dispatches it. Under the separation ADR-1143 itself asserts it never had a legitimate channel; ADR-1143's own audit already records the end-to-end path has never been exercised. Wiring it properly needs a host-level mechanism that does not exist today. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#4740): invert the stale execute:wave:pre registry assertions Removing the contribution left four surfaces asserting or describing the old state. Caught by an isolated review before a verification run was spent, which is the point of reviewing first: the first of these was a guaranteed CI red. execute-wave-post-gate-pipeline-e2e asserted against the REAL generated registry that byLoopPoint['execute:wave:pre'] held exactly one contribution with capId claude-orchestration. It now holds zero. Inverted to assert exactly 0 -- not a vague >= 0 -- and the #2285 comment above it now explains the current state rather than the one it was written for. CONTEXT.md's Claude Orchestration entry claimed two contributions at wired points. It is now one, and the entry's execute:wave:post label was already wrong before this change: the manifest said execute:wave:pre. Rewritten to one plan:post contribution, why the execute-point one was removed, and where the procedure now lives. One assertion in claude-orchestration.test.cjs could not fail. It tested for the prose "(into the executor)" while the doc says "(`into: executor`)", so no plausible wording matched it and the paired plan:post assertion was carrying the row. Replaced with a check on the structural claim, and proved RED by restoring the two-contribution wording before reverting. The moved procedure keeps section headings that speak as a live contribution -- "When this contribution is active", "Why execute:wave:pre". Preserving the body verbatim was deliberate, so the headings stay and an editor's note under the header explains why they read that way. A sweep of all 17 files referencing byLoopPoint found no further siblings: the remaining hits are a synthetic capability fixture and an empty-points test that already expected no active hooks, both correct before and after.

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.
Proposedmeans 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 toAccepted, each carrying a dated Ratification section with the evidence (see ADR-857 for the fullest example). The ADRs that remainProposedareProposedfor 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 staleProposed.
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.mdreferences 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.
2. Cross-references to other ADRs are file links, never bare ids
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 becomesSuperseded.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.
3a. Amendment is symmetric too — but not yet gated
A same-file ## Amendment (YYYY-MM-DD): <topic> section (see docs/contributor-standards.md's "Amending an accepted ADR") needs no back-link — there is only one file. A separate ADR that amends another is the same relation as Supersedes/Subsumes and follows the same rule: if A declares **Amends:** [ADR-B], B must carry the reciprocal **Amended by:** [ADR-A] in the same PR. ADR-2782's single Amends field names four targets — ADR-857, ADR-894, ADR-1016, ADR-1244 — and all four carry the reciprocal Amended by back-link.
Unlike Supersedes/Subsumes, this is not yet enforced by scripts/gen-adr-index.cjs — relationSections() only recognizes ## Supersedes / ## Subsumes headings, and the header-field parity check does not walk Amends. Get the back-link right by review until that gap closes.
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.
6. Every relative link resolves
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 at0001-alpha.mdfails 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:
- The decided mechanism demonstrably exists in the tree — name the files, symbols, and tests.
- The owning issue is closed as completed. A closed issue is not proof:
stateReasonof not planned / duplicate means the decision was dropped (that isLegacyorRetired, notAccepted). - 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. - 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).
