* test(#3023): failing-first guard — pi must not stage hooks in its reserved dir pi reserves <configDir>/hooks as its deprecated extension location and warns on every startup when it exists. Assert a pi install stages the shared hook bundle under gsd-hooks/ instead, manifests it there, and never creates hooks/. Also adds pi to the local-scope dir table in install-shared.cjs: pi was in RUNTIME_META but not LOCAL_DIR_NAME, so scope:'local' resolved path.join(root, undefined) and no local pi install could be exercised. Fails before the fix. Verified via the remote runner. * fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ dir pi reserves <configDir>/hooks as its now-deprecated extension location and warns on every startup when that directory merely exists — checkDeprecatedExtensionDirs() guards the warning with a bare existsSync(), unlike its tools/ sibling. GSD staged its shared hook bundle exactly there, and pi's advised remediation (move it to extensions/) would break the adapter's paths and expose GSD's .js helpers to pi's extension auto-discovery. The bundle directory name is now runtime-descriptor-driven: hostBehaviors .sharedHooksDirName, defaulting to 'hooks' so all 18 other runtimes are byte-identical. pi sets 'gsd-hooks'. The name is validated as a single path segment — separators, dot-only segments, trailing dots, absolute paths, NUL, and Windows reserved device names all fall back to the default, because the value is joined onto a user's config root and written to. Renamed in place rather than relocated: hook scripts resolve siblings via __dirname/.., so a depth change would silently break them. - install / uninstall / manifest sites all read the resolved name - pi/gsd.cjs probes gsd-hooks then hooks, so dev checkouts and half-upgraded trees still resolve; the never-throws contract is preserved - new migration 009 retires the legacy pi hooks/ dir on upgrade, using a new non-recursive remove-empty-dir engine primitive (rmdirSync only, symlink-refusing, containment-guarded); ADR-0008 amended accordingly - fixes two latent name-dependencies the rename exposed: the stale-hook scan and the injection scanner's self-exclusion both hardcoded 'hooks' Verified on the remote runner. Closes #3023 * fix(#3023): close review findings and align emitted provenance with the rename Adversarial review found two defects, and the remote runner found four failure clusters. All fixed here. Review BLOCKER — detect-custom-files was blind to the renamed bundle. GSD_PREFIX_MANAGED_DIRS in gsd-tools.cjs hardcoded 'hooks', so for pi the whole gsd-hooks/ tree was invisible to the custom-file scan and user-added files there were never backed up before the next update's clean-install wipe. The dir set now resolves via the .gsd-runtime marker plus the shipped capability registry (never bin/install.js, which is not shipped into installed trees), and falls back to scanning every known candidate when the runtime cannot be determined — over-scanning is safe, under-scanning is the data loss. Review MAJOR — the pi adapter bound to an empty bundle. resolveSharedHooksDir accepted any directory, so an interrupted install left gsd-hooks/ winning over a fully-staged legacy hooks/ and every hook silently no-opped. A candidate now qualifies only if it is non-empty. Remote-runner clusters: - emitted-provenance had no rule for the gsd-hooks/ family; added two pi-scoped rules pointing at the same sources the existing hooks/ rules use. The table is total, so an unattributed family is a hard failure by design. - pi tests in install-minimal-hooks and the install integration suite asserted the old layout; updated to derive the dir name from the descriptor rather than hardcoding either name. - 19 unrelated-looking failures on node22 only were a leaked fs mock: t.after() runs in registration order, cleanup was registered before mock.restoreAll(), and node22's JS rimraf calls the public fs.rmdirSync while node24's native path does not — so the EACCES stub leaked process-wide on one lane. Restore now runs first. Verified on the remote runner. * fix(#3023): honor PI_CODING_AGENT_DIR, ack the rename ripple, fix expandTilde pi resolves its agent dir as PI_CODING_AGENT_DIR ?? ~/<CONFIG_DIR_NAME>/agent (packages/coding-agent/src/config.ts). GSD's pi descriptor declared an empty configHome.env, so a user with that variable set had GSD installed where pi never looks. Added the env name; the dot-home-nested resolver already handled the override, so no resolver logic changed. Also fixes expandTilde in the shared runtime-homes resolver, found while adding that: it hardcoded os.homedir() and ignored the opts.home every caller threads, so EVERY runtime's tilde-valued env override (claude, antigravity, windsurf, pi) silently resolved against the real home. That is a correctness bug and a test-escape hazard — a sandboxed test asserting on a tilde override reached the developer's actual home directory. Now threaded through every branch; behavior with no injected home is unchanged. Adds the emitted-drift ack fragment for the 58 pi paths whose emitted location moved with the rename. The provenance rules satisfy the totality gate; the differential gate needs the ack because the hook sources are byte-unchanged — only the installer's target directory moved. The two hook files this branch genuinely edits stay attributed and are not double-acked. Note on piConfig.configDir: it is read from pi's OWN installed package.json (getPackageDir walks up from pi's __dirname), alongside piConfig.name — a white-label setting for a redistributed pi fork, not a per-project user setting. Documented accordingly rather than treated as an unsupported override. Verified on the remote runner. * fix(#3023): reject blank env overrides, pin adapter/descriptor parity Three review findings, all fixed. A whitespace-only config-dir override was accepted verbatim: the guard was `if (val)`, falsy only for the empty string, so PI_CODING_AGENT_DIR=' ' resolved to a literal three-space directory name instead of falling back to the descriptor default. Fixed across every env-consuming branch — dot-home, dot-home-nested, all three xdg steps, and generic-agents-root — not just pi's. Non-blank values are still never trimmed, so '~/My Agent Dir' keeps working. pi/gsd.cjs's probe list and the descriptor were two independent sources of truth for the bundle directory name; a future rename would have desynced them silently and left every pi hook quiet with no error. The probe list stays deliberate — it must resolve in a dev checkout and a half-upgraded tree, where the registry's answer would be wrong — so this adds the parity assertion the repo's generative-fix-divergence rule calls for: the descriptor value must be the FIRST candidate, and the default must remain present. Changeset body rewritten to cover the two later user-facing fixes it had not caught up with. Verified on the remote runner. * chore(#3023): backfill changeset PR number * fix(#3023): anchor injection-scan patterns and fix a macOS detection hole CI's security job flagged CONTEXT.md:124 — pre-existing prose reading 'not the same fact as a genuinely empty or absent one'. The match was the 'act as a' INSIDE 'f-act as a': the pattern had no left word boundary, so any word ending in act tripped it (fact, impact, contract, artifact, interact, redact, abstract). My four-line CONTEXT.md edit dragged the latent false positive into this PR because the scan is diff-scoped by file but reads whole files. Anchored with (^|[^[:alnum:]]) rather than rewording maintainer-owned prose, which would have left the class alive for the next PR touching any file saying 'fact as a'. Auditing the rest of the list for the same class surfaced a real detection hole: the eval/exec/Function patterns matched a quote via \x27, a GNU-grep-only hex escape. BSD/macOS grep reads it as four literal characters, so single-quoted eval('...')/exec('...') payloads were NEVER detected there while passing on GNU-grep CI. Replaced with a literal apostrophe class. Boundaries were added only where a real word-suffix collision exists; exec, jailbreak, developer mode and the role-manipulation family were audited and deliberately left unanchored. 22 new cases cover both directions — the false positives now scan clean, and every real payload still fires, including the quote/punctuation/start-of-line boundary forms. Also builds this branch's injection test fixture at runtime instead of carrying the literal phrase, so the payload keeps its teeth without tripping the scan. Verified on the remote runner. --------- 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).
