* test(#3241): failing-first suite for the codex passive model posture Locks ADR-2313's D1-D5 before any production code exists, so the tests bind to the behavior rather than to whatever the implementation happens to do. Red-first (fail against the current tree): - the resolver path emits no `model` and no `model_reasoning_effort` - a whitespace-only model_overrides value yields no pin - isAnthropicFlavoredModel / CLAUDE_AGENT_ALIASES on model-catalog - the one-time install notice, and its once-per-install dedupe Regression guards (pass today, must keep passing): resolver-null via `inherit` and via absent runtime; a resolver that resolves to nothing; empty-string and non-string overrides; and the light-tier service_tier/model_verbosity fields, which are NOT coupled to the model pin and would silently regress if the implementation coupled them. Classifying each test as red-first or regression guard is deliberate. A test that passes on both sides of the change proves nothing, and this epic has already shipped two such rows before catching them. The whitespace case is a live defect, not a quirk: `' '` is truthy, survives the type guard, is not Anthropic-flavored, and is embedded verbatim as `model = " "` — the same class the #2310 guard exists to stop. Same function, same path, fixed in this phase per CLAUDE.md §3. Two matrix rows were dropped as vacuous rather than shipped green: a 64-char truncation case (the pinned notice interpolates no user-controlled value, so it cannot exhibit truncation) and a newline hazard that the input surface cannot reach. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#3241): omit the codex per-agent model by default Implements ADR-2313 D1-D5. generateCodexAgentToml no longer embeds the runtime resolver's per-tier Codex model, so an agent inherits the always-available session model instead of a pin a ChatGPT-account Codex may not expose. model_reasoning_effort disappears with it via the existing hasPinnedModel coupling (#838) — no logic change needed there. Supersedes #2517's embedding on the default path only. An explicit real-Codex model_overrides pin is still embedded verbatim, and the #2310 Anthropic-flavored guard is retained: the model_overrides route to it is still live even though the resolver route is now unreachable. The shared rule moves down a layer. CLAUDE_AGENT_ALIASES leaves model-resolver for model-catalog — a genuine leaf importing only node:path and its own JSON — with isAnthropicFlavoredModel defined beside it, and is re-exported from model-resolver so every existing importer is untouched. This is what lets Phase 2's install-check and Phase 3's sync consume the rule without taking the config-loader dependency model-resolver would have dragged into a module documented as pure read/verify with 33 dependents. A parity test fails if the two ever fork. Also fixes a live defect surfaced while writing the tests: a whitespace-only model_overrides value was truthy, survived the type guard, was not Anthropic-flavored, and so was embedded verbatim as `model = " "` — the same class the #2310 guard exists to stop, reached by a different route. Trimmed before the truthiness test. It is deliberately not routed through _warnCodexModelOverrideDropped, whose text would misdescribe a blank field as a mis-typed model. Adds the one-time install notice (maintainer direction, recorded as an ADR-2313 amendment): one stderr line naming model_overrides and the session model, deduped per install rather than per agent, and emitted only for the population that actually loses a pin. service_tier and model_verbosity stay decoupled from the model (#774); a regression guard asserts they still emit with nothing pinned. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3241): amend ADR-2313, add the model-catalog glossary entry ADR-2313 gains two dated amendments rather than edits to its merged text, since ADRs here are append-only. The first records that a deprecation notice IS offered, reversing the Migration section's "no deprecation window" position, and states why that position was wrong rather than just superseding it: the ADR identified the API-key population as losing something real and then declined to warn it, in the same document. Hyrum's guidance was applied to the recourse and not to the notice. The second records the whitespace-only model_overrides defect and notes that D2 always implied the fix — the implementation simply never enforced it and no test covered the case. CONTEXT.md gains a Model Catalog Module entry. The module had none, which is why the glossary gate passed without one: check-glossary-refs verifies that references resolve, not that modules are documented. The entry records why the Anthropic-flavored rule lives there rather than in model-resolver, so a later reader does not "helpfully" move it back. The Model Resolver entry is updated to point at its new home and note the back-compat re-export. docs/CONFIGURATION.md carried a claim that is now false: that the resolved tier ID is embedded into agent frontmatter at install time on codex and opencode. Corrected to name codex as the exception, with the 400 symptom and the model_overrides recourse. Changeset leads with the user-visible change and the migration line rather than the implementation, per the ADR's Hyrum's-Law analysis. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3241): only notice a lost pin when one was actually embeddable Review finding from an isolated reviewer. The deprecation notice gated on whether the runtime resolver would have returned *any* model, but the question that matters is whether that model would have been *embedded*. Those differ. The #2310 safety gate already rejected an Anthropic- flavored model arriving from the resolver path before Phase 1 — so for a mixed-runtime config resolving to a claude-* id against a Codex install target, the user never had that pin. The notice told them they lost something they never got, and pointed them at model_overrides for no reason. The existing #2310 test drives exactly that path but asserts only the emitted `model` line, never stderr, which is why it slipped through. Now covered. Deliberately unchanged: an Anthropic-flavored model_overrides value plus a legal resolver model fires BOTH the override warning and the notice. That is correct — pre-Phase-1 the guard dropped the override, execution fell through to the resolver, and the resolver's model was embedded, so that user did lose a pin. Two messages, two distinct true facts, and the prefixes differ (`gsd: warning — ` vs `gsd: notice — `) so the one-notice-per-install contract holds. A regression test now pins that behavior so it does not get "simplified" away. Of the three tests added, only the first is red-first; the other two pass on both sides by design and are labelled as guards — one against over-correcting the fix into silence, one against removing the intentional double message. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3241): reset the notice dedupe via a seam, not a require.cache bust The remote runner caught a regression I introduced: the #2760 post-write-validation test began failing with the validator override no longer intercepting. Cause, confirmed by trace rather than guessed: the new #3241 review tests deleted require.cache for bin/install.js and re-required it mid suite, to clear the notice's module-level dedupe flag. But runCodexInstall destructures `install` at file load, closing over the ORIGINAL module's exports. After the cache bust a second instance existed, so the test's `installModule.__codexSchemaValidator = ...` mutated the new object while the code under test still called the old one. The override silently stopped intercepting, the real validator ran and passed on GSD-emitted output, and the abort-and-restore path was never exercised. Cache-busting a module mid-suite breaks every later test that assumes a single instance, which every other test in the file is entitled to. So the fix is a seam, not a workaround: bin/install.js exports _resetCodexNoticeDedupeForTests(), and the three tests call it directly instead of reloading the module. The flag is module-level by design — the dedupe is per-install and install() already resets it — so a unit test driving generateCodexAgentToml directly needs an explicit way to reset it. That is now what it has. Swept the rest of the #3241 diff for the same hazard; this flag was the only shared module-level state introduced. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3241): reset both codex dedupe stores, not just the notice flag Second incomplete fix, same class one layer down. bin/install.js keeps TWO module-level dedupe stores and the require.cache bust I removed had been papering over both; my replacement seam cleared only one. _codexModelOverrideDroppedWarned is a Set keyed `${agent}::${value}`. tests/codex-config.test.cjs:558 already emits for `gsd-executor::sonnet`, so by the time the review test using the same agent and value ran, _warnCodexModelOverrideDropped was a silent no-op and the expected warning never appeared. The seam now clears both stores and is renamed to say so. Its comment records that per-install dedupe lives in module scope deliberately and that this is the single sanctioned way for a unit test to clear it. Swept bin/install.js for every other module-scope mutable a test could latch. Two are inert (capability registries assigned once at require time; selectedRuntimes computed once from argv). One is a genuine latent hazard and is deliberately NOT folded in: attributionCache (:1654) memoizes getCommitAttribution by runtime name for process lifetime, so two in-process installs of one runtime with differing attribution config would collide. It is unreachable from any current test and is a different concern from Codex warning dedupe, so it stays out of this PR rather than widening it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3241): correct the codex tier-routing how-to The docs gate forced the task-oriented quadrant and found the worst defect in this change's documentation surface. docs/how-to/configure-model-profiles.md carried a section titled "If you want tiered models on Codex" telling users to set runtime:codex + model_profile:balanced, promising "GSD resolves each tier alias to the Codex-native model and reasoning effort defined in the runtime tier map." That is exactly the behavior this PR removes — a how-to page confidently instructing users to do something that no longer works, which is worse than a missing page because it fails at the moment of use. Rewritten to state that Codex does no tier routing, give the model_overrides pin as the supported alternative, and name the two constraints on what may be pinned: it must be a real Codex model id, and the account must actually expose it — GSD cannot verify the second, so the honest advice when unsure is to omit the pin. Carries an upgrade note for both account types, since the change is a no-op for ChatGPT accounts and a real loss for API-key ones. Also tightened the same page's claim that Codex "embeds the resolved model" at install time — now true only of an explicit override. The re-install instruction it supports is still correct and still needed, so only the premise moved. Both the required-docs set (COMMANDS.md + FEATURES.md) and lint-docs-required.cjs would have passed before this commit, since CONFIGURATION.md and the ADR had already moved. Neither checks the quadrant a user in trouble actually opens.

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.
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).
