* test(#2929): capture prompt-budget parity corpus pre-refactor Phase 2 of epic #1671 generalizes prompt-budget's trim ladder into a shared context-composer seam. Its success condition is that review-prompt output does not change, and the only authority on "did not change" is the behavior that shipped before the refactor. Capture that behavior now, while it is still the live implementation. 47 characterization cases, every `expected` value computed by executing the current implementation rather than hand-authored — the independence CONTRIBUTING.md "Fixture provenance (#2371)" asks for. A corpus is only worth what it can detect, so this one was validated by mutation rather than assumed. Five deliberate defects were injected and each must be caught by at least one case: - the note reserve deducted unconditionally instead of only under pressure - the pressure test relaxed from `>` to `>=` - a no-op head-shrink still setting the shrunk flag - the per-plan floor dropped from the proportional share - drop order reversed Two of those exposed real holes in the first cut of this corpus, and the cases that close them exist because of it: - `>=` was caught by NOTHING. At exact cap the only trimmable fragment was a floored plan group, and the 1024-char floor absorbed the entire trim, so the mutation was byte-invisible. A3b/A3c put a droppable at exactly the cap, which makes the strict inequality observable as context kept vs omitted. - No case reached proportional-truncate at all — B6 and B7 both hard-failed the min-set pre-check first, leaving planTruncationPct at 0 across every case and the floor semantics entirely unexercised. Rebudgeted to 700 and 1100 so the min-set fits and the truncate step is actually reached; they now record 40.20% and 48.80%. The A4/A10 families sweep the pressure boundary from both sides, which is where this function has regressed before: CONTEXT.md's LEARNING.prompt-budget.boundary-gap records PR #3708 shipping two regressions that only fired when the baseline sat inside the NOTE_RESERVE_TOKENS band, because the suite paired a trivially-fitting budget with a trivially-overflowing one and never sampled between them. A4 pins that nothing is trimmed from the cap down to 81 tokens under it; A10 pins that pressure fires at +1. Together with A3b/A3c they satisfy row (d) of RULESET.TESTS.boundary-coverage.fixtures. Two facts the corpus establishes that the design notes had wrong: - "" and null sections are NOT distinguished. applyBudget uses truthy checks throughout, so an empty-string section is treated as absent: not rendered, not dropped, never recorded in `omitted`. B13b pins this while the ladder is actively trimming, where only the non-empty `research` is dropped. - Sizing matters. B12/B13 were first written at a budget where both hard-failed the min-set check and returned "", so comparing them compared two empty strings and proved nothing. Committed as its own commit, ahead of the refactor, and regenerated against the pre-refactor implementation, so the oracle is demonstrably independent of the change it will adjudicate. Refs #2929 * refactor(#2929): extract the context-composer seam from prompt-budget Epic #1671 needs prompt-budget's budget-trimming logic for a second consumer — per-runtime artifact emission — but it is walled inside the cross-AI review pipeline. Lift it into a shared seam so later phases can call it, without changing what the review pipeline emits. ADR-1671 specifies the composer as "priority + binary-search cutoff to a per-runtime budget". Read against the code it generalizes, that contract cannot express the thing being generalized. applyBudget is not a cutoff: it is a fixed five-step ladder in which each section carries its own shrink strategy, and only three of its eight sections are ever dropped. PROJECT.md is head-shrunk to N lines; plans are proportionally tail-truncated with a per-plan 1024-byte floor; instructions and roadmap are never touched at all. A cutoff composer sorts by priority and discards the tail — it has no way to say "shrink this one", "truncate that one but never below 1 KB each", or "these three are the only droppables, in this order". Building to the literal contract and routing prompt-budget through it would have silently changed review-prompt output, which is the one outcome this phase forbids. So shrink strategies are the core abstraction here, and cutoff becomes one strategy among them — the right one for per-runtime emission in Phases 3-4, not for this ladder. That is an elaboration of the ADR's intent, not a departure from it, and ADR-1671 is updated to say so. Three decisions worth stating: - The composer DECIDES; the caller RENDERS. composeWithinBudget returns a plan of surviving fragments and never a string. assemblePrompt's rendering is prompt-shaped (`## Roadmap`, `### <file>`, the note in position two), and owning it in the composer would force emission to adopt prompt-shaped rendering. The split is what lets one seam serve both consumers. - The budget unit is INJECTED via `measure(text)`. prompt-budget passes its chars/4 estimator; emission will pass a byte counter, which ADR-1671 requires for emission caps. The existing code converts a token budget to a character budget with a hardcoded `* 4`; that assumption is now an explicit `charsPerUnit` inverse, which is precisely what a byte unit needs in order to reuse this. - The entry point is `composeWithinBudget`, not `applyBudget`. That name already exists twice — src/prompt-budget.cts and src/graphify.cts, the latter being an unrelated graph-edge budget. A third would make every symbol search in this repo ambiguous, and it already misresolves: preflight and impact queries for "applyBudget" return graphify's. Behavior is unchanged and proven so: all 47 characterization cases reproduce byte-identically, and the corpus is mutation-validated rather than merely green (see the preceding commit). prompt-budget.cts drops from 436 to 343 lines and from eighteen mutable accumulators to two, both inside a helper copied verbatim. estimateTokens deliberately stays in prompt-budget and keeps its exact math: src/phase-estimation.cts re-exports it as measureTokens, and CONTEXT.md pins plan estimates and recorded actuals to that same scale, so moving or changing it would silently break the calibration loop. Refs #2929 * docs(#2929): document the context-composer seam and amend ADR-1671 Adds the INVENTORY row, the CONTEXT.md glossary entry (a PR gate for new domain modules), and a mutation-matrix entry for the new module. The ADR amendment is the substantive part. ADR-1671 specified the composer as "priority + binary-search cutoff to a per-runtime budget". Implementing Phase 2 established that a cutoff alone cannot express the function the platform generalizes, so the ADR now records shrink strategies as the core abstraction with cutoff as one strategy among them, reserved for per-runtime emission in Phases 3-4. Recording it in the ADR matters because Phases 3-6 are planned against that contract and would otherwise be planned against a mechanism that does not work. The mutation-matrix entry is not bookkeeping. Stryker scores per module against a named .cjs, so relocating the ladder out of prompt-budget.cjs would leave the extracted code unmeasured while prompt-budget's own score floated free of the logic it used to cover. context-composer gets its own entry at the same floor. Refs #2929 * test(#2929): pin the effectiveBudget rounding mode in the parity corpus An isolated correctness review found a real blind spot: mutating `Math.floor` to `Math.round` in the effectiveBudget calculation failed ZERO of the 47 corpus cases. Every (budget, safetyMarginPct) pair in the generator happened to produce a whole number, so floor, round and ceil all agreed and the rounding mode was entirely unpinned by a corpus whose whole job is to pin observable behavior. Three cases fix that by straddling the .5 boundary: A11 95 * 0.90 = 85.5 floor 85, round 86 -> the two disagree A12 97 * 0.90 = 87.3 floor and round agree; ceil (88) does not A13 93 * 0.85 = 79.05 same guard at a non-multiple-of-10 margin, so the margin arithmetic is exercised and not just the budget A11 alone catches the round mutation; all three catch ceil. Regenerated against the pre-refactor implementation (`git show 9557f8552:src/prompt-budget.cts`), so the expanded corpus keeps the independence property the original capture had. The corpus is now mutation-validated against seven injected defects, every one caught: unconditional note reserve, `>` relaxed to `>=`, no-op head-shrink setting its flag, the truncate floor ignored, drop order reversed, and both rounding-mode changes. Refs #2929 * feat(#2929): flexReserve floors and the byte-stable isolate prefix Two of issue #2929's "Done when" items were unimplemented rather than deferred, and an isolated review flagged them alongside my own audit. Both are part of ADR-1671's composer contract, so shipping the seam without them would have left Phases 3-4 building against a contract that does not exist yet. flexReserve is a per-fragment floor in measure units that every strategy must respect, which is what makes it different from the pre-existing floorChars: that one is a chars-denominated detail of proportional-truncate alone and is retained unchanged. A floored fragment is never dropped, is never head-shrunk below its floor, and raises its own proportional cap. A fragment already smaller than its floor is untouchable outright. Metadata gains `floored`, listing the ids whose floor actually prevented a trim — a guarantee no caller can observe is a guarantee no test can hold you to. isolate marks the byte-stable canonical prefix the ADR calls for: never trimmed, never dropped, but still counted, because a prefix excluded from accounting would silently under-count real context. Metadata gains `isolatePrefix` so a caller can hash or assert on the exact bytes. Declaring an isolate fragment after a non-isolate one throws: a prefix that is not at the front is not a prefix, and accepting it would make the cross-runtime stability claim meaningless. Adds tests/context-composer.test.cjs for the exact new semantics and tests/context-composer.property.test.cjs for the five invariants, including the budget-monotonicity property the issue names explicitly. Both are registered in the mutation matrix, since coverage does not migrate with relocated code. prompt-budget uses neither feature, and its output is unchanged: all 50 corpus cases still reproduce byte-identically. Refs #2929 * chore(#2929): allowlist the prompt-budget parity suite The parity corpus needs its own test file and that makes prompt-budget a three-file module against a limit of two. The lint offers consolidation or an allowlist entry with justification; the entry is the right call here. Consolidation would mean folding the characterization suite into prompt-budget.test.cjs, which is the one thing that should not happen to it. The parity suite is a distinct concern with a distinct lifecycle: it is generated rather than hand-written, it is named by scripts/mutation-matrix.cjs as its own scoring target, and its failure means something categorically different from a unit-test failure — not "this behavior is wrong" but "observable output moved". Burying it inside a general unit file would obscure exactly that signal. The allowlist is an identity ratchet, so this entry pins today's three exact filenames: adding a fourth still fails, and dropping back to two requires removing the entry. Refs #2929 * fix(#2929): register the new module with two gates it was missing The remote matrix caught three defects that no local check could, because the local runner is blocked in this repo and these suites had therefore never executed. Eight failures, identical on node22 and node24, so nothing environment-shaped. Two are the new-module ripple. A net-new src/*.cts lands in six places and this change had reached four of them — .gitignore, INVENTORY, the manifest, and the CONTEXT.md glossary — while missing the ESLint ignore list (tsc OUTPUTS must not be linted; repo-invariants asserts linted-xor-ignored) and the mutation ratchet baseline (a deliberate review-visible mirror of the matrix floors, which every COVERED module must carry). Both are now registered, the ratchet at the same floor of 66 the matrix declares. The third was a test asserting an outcome it had made impossible. It set budget:1 alongside a 400-char required fragment, so the group budget came out at -99 and the proportional-truncate step was skipped entirely — the deliberate "non-positive group budget is skipped, never clamped" rule inherited from the original ladder. Nothing was trimmed, and the test then asserted a truncation. Rebudgeted so the step actually runs, with the arithmetic written out in a comment so the next reader does not have to re-derive why 120 rather than 80. Fixing that surfaced a genuine bug in the composer. `floored` is documented as recording fragments whose flexReserve prevented a trim that would otherwise have happened, but the push sat in the else-branch of "content did not change", so it only fired when nothing was trimmed at all. A fragment truncated to a reserve-raised cap has also had a trim prevented — 40 characters' worth in the test above — and was silently absent from the field that exists to make the guarantee observable. The condition was already right; it was in the wrong branch. Now recorded on both paths: a drop prevented outright, and a truncation capped higher than the share alone would have allowed. Parity is unaffected — prompt-budget never sets flexReserve, so the branch is unreachable from every corpus path, and all 50 cases still match.

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).
