* refactor(#3216): widen milestone-window guard to literal-## matchers The guard keyed only on the `#{N,M}` quantifier plus a literal version or phase-lookahead token. getMilestoneInfo hand-rolls its milestone-heading match with a literal `^##`/`## ` and an interpolated ${escapedVer}, so it satisfied neither token and the guard reported a clean zero on a file carrying live re-derivations (#3171, #3197) — a zero it did not earn. Widen token (a) to a literal 2-6 `#` run, admitted ONLY inside a heading-MATCHER literal (a regex literal, or a string/template handed to new RegExp) so a heading-BUILDING template is not mistaken for a re-derivation. Widen token (b) with the grouped `v(\d+(?:\.\d+)+)` shape and an interpolated version placeholder. Ships BEFORE the consolidation per ADR-3180 s7.2: a guard widened afterwards measures an already-cleaned surface. It is expected to be RED until the consolidation lands. * test(#3216): failing-first milestone-identity single-owner suite 63 tests across two files, from the matrix in .gsd/phase/. Section H of milestone-window-single-owner.test.cjs covers the 21 input classes of the design's behavior table plus its negative space; milestone-window-drift-guard covers the widened tokens and proves the exemption is function-scoped, not file-scoped. Copy count is 3 found by the guard, not 1 per the epic (ADR-3180 Amendment 3's standing rule, holding for the fourth consecutive phase): both getMilestoneInfo sites plus cmdRoadmapAnalyze's milestone enumeration at roadmap.cts:454, which carries the same #3171 truncation and #3197 phase-heading confusion. Expected RED until the consolidation lands. * refactor(#3216): bind milestone identity to the canonical locator getMilestoneInfo hand-rolled two milestone-heading regexes inside the owner's own file. Both were wrong, differently: the STATE-version site's ^## anchor is level-blind so [^\n]* absorbs a third #, and the fallback site had no anchor at all, so '## ' matched from the second # of '###'. Against '### Phase 7: Close v3.3 gaps' the fallback returned {v3.3, gaps} (#3197). Both captured names with [^\n(], truncating at a parenthetical (#3171). Bind both to the canonical grammar. locateMilestoneHeadings becomes a version-filtered view over one shared source, and a new version-agnostic listMilestoneHeadings enumerates milestone headings for callers that need all of them. getMilestoneInfo returns ScopedResult<MilestoneInfo|null>; the {v1.0,'milestone'} default, which was output-identical to a real v1.0 project, is deleted. The #2245 never-throws invariant is preserved. Copy count: 3 found by the guard, not 1 per the epic. The third was cmdRoadmapAnalyze's own milestone enumeration (roadmap.cts:454), carrying both defects in the implementation the epic blessed. buildStateFrontmatter and archivePhaseDirectories branch on scope: the first writes null rather than a fabricated identity, the second falls through to its dated-label fallback. A fabricated v3.3 passes ARCHIVE_VERSION_LABEL_RE, so it would otherwise misfile phase history. Also fixes an unsafe cast in init.cts that masked these type errors across five call sites, which would have shipped undefined milestone fields under green tsc. * fix(#3216): restore the #1761 unbounded guard and bullet precedence Review and the first full-matrix run surfaced five real defects in the consolidation, all fixed here rather than by relaxing the tests that caught them: - buildStateFrontmatter gated its isMilestoneBoundedInRoadmap check on the scope-gated milestone value, which is null on any non-COMPLETE scope, so the #1761 unbounded guard was silently skipped and state json reported a percent it must omit. It now gates on the STATE-asserted version, independent of identity scope. - The rewrite lost #2135's precedence: the name-bearing progress-marker bullet is consulted before the heading again. - A single-segment version (v3, no dot) did not resolve; the name-extraction fallback now accepts it. - A version carrying regex metacharacters, or a $& / $1 replacement pattern, is matched literally. - listMilestoneHeadings' heading field trimmed, so a CRLF roadmap no longer leaks a trailing carriage return into roadmap analyze's output. Also emits milestone_version / milestone_name / current_milestone as explicit null rather than omitting the key, so the prompt layer cannot render a bare placeholder, and corrects an init.cts comment plus a cast left inconsistent. * test(#3216): update milestone-identity expectations to the scoped contract getMilestoneInfo returns ScopedResult<MilestoneInfo|null> and the {v1.0,'milestone'} default is deleted, so the suites asserting the old shape assert removed behavior. Updated rather than weakened: every touched call site now asserts the scope explicitly against the frozen SCOPE enum. roadmap-parser.test.cjs: 20 expectations moved to {value,scope}. The #1881 unreadable-vs-absent diagnostic assertions are untouched and still prove their original point — only the return shape moved. One pre-existing assert.ok(info) is now a specific UNSCOPED assertion, so that case is stronger than before. new-milestone-clear-phases.test.cjs: the test asserting phases clear archives under the v1.0 default now asserts the dated archived-<YYYYMMDD> fallback, which is the deliberate consequence of deleting that default. Two of this branch's own tests were also corrected after they drove the implementation the wrong way: the parity test compared raw heading text and so pushed a stray ## prefix into roadmap analyze's public output, and the hostile metacharacter row demanded a pathological version resolve, which pushed a widening of the ADR-locked \b boundary. Both now assert what the contract actually requires. * docs(#3216): document milestone identity and correct the CONTEXT.md entry ADR-3180 s7.2 moves to Enforced and gains two rules that were unstated: the name derives from the heading's own version token and drops a trailing status marker, and a free-form legacy ROADMAP with no version anywhere is UNSCOPED with no identity rather than a defaulted v1.0 (decided by the maintainer before implementation, per s7's own rule that an unstated behavior is not decided). Amendment 4 records Phase 6's validation, including that the copy count was a lower bound for the fourth consecutive phase. CONTEXT.md's Roadmap Parser entry described locateMilestoneHeadings as boundary-matched with (?![\w.-]) — the alternative Amendment 2 tried and REVERTED. The code uses \b and says so, and the ADR agrees; the revert updated code and ADR and missed CONTEXT.md, which is the epic's own fixed-on-one-copy failure class in the docs layer, on a file that is itself a PR gate. * fix(#3216): persist the real version on a truncated identity buildStateFrontmatter wrote null for BOTH milestone and milestone_name on any non-COMPLETE scope, discarding a real version. ADR-3180 s7.2 rule 6: a version known with no resolvable name is TRUNCATED carrying {version, name: null} — 'the version is a real answer, the name is a non-answer, and collapsing the two is the failure this contract exists to prevent.' The two fields are now gated by what is actually known: the version whenever one exists (COMPLETE or TRUNCATED), the name only on COMPLETE. Never fabricated. Caught by this phase's own Decision 4(c) consumer-output test, which is the argument for asserting at the consumer rather than the owner — the owner was correct throughout; only the consumer collapsed its answer. * refactor(#3216): extract helpers and make cmdCommit's scope gate explicit From the two-axis code review: - init.cts repeated the identical getMilestoneInfo cast at five sites with copy-pasted comments — duplication inside a PR whose thesis is that duplicates get deleted. Extracted milestoneRecord(cwd); the one site-specific comment is kept, the four generic copies removed. - getMilestoneInfo hand-built its { value, scope } literal at ten return points; a local scoped() constructor now does it once. Every per-branch rationale comment is preserved and no returned value or scope changed. - cmdCommit gated the milestone branch name on plain truthiness, which is also true for TRUNCATED, so an unresolved identity drove branch creation incidentally rather than deliberately. It now gates on the SCOPE enum, accepting COMPLETE or TRUNCATED because both carry a real version, and the comment records why that differs from archivePhaseDirectories — which demands COMPLETE because it uses the value as a filesystem path component. * test(#3216): cover the bare-version-in-prose truncated path The spec review found the bareVersionMatch path — no STATE version, no milestone heading, a version token only in prose — returning TRUNCATED with no test exercising that exact shape, violating Decision 4's boundary-coverage requirement. * docs(#3216): record the missed Tier-2 surfaces and rule 5's corollary Decision 3 requires an explicit call-out for EVERY Tier-2 change, and Amendment 4's first draft named eight surfaces while the change touched thirteen. Adds cmdCommit's branch-name construction and the four init JSON bundles, an incomplete list being the same defect in miniature that this epic removes. s7.2 rule 5 gains a corollary separating two cases the original wording ran together: no version token ANYWHERE is UNSCOPED, while a bare version token in prose or a non-milestone heading is weak but real evidence and yields TRUNCATED under rule 6. * chore(#3216): set changeset fragment pr to 3226 --------- Co-authored-by: sim <sim@local>
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.
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.
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
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.
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).
