Tom Boucher c0b2a05d2f fix(#4594): one canonical dispatch-identity owner — the emitted format and the parser that reads it back (#4693)
* fix(#4594): give dispatch identity one owner for the emitted format and its parser

The isolation guards decided whether a run-scoped sentinel applied to a
dispatch by regex-scraping model-authored prose. The scrape returned values in
a different namespace from the ones the sentinel records, so the comparison
could never succeed:

  sentinel  { phase: "03", plan: "03-02-hardening" }   <- $PHASE_NUMBER / $plan_id
  prose     "Execute plan 02 of phase 03-auth."
  scraped   { phase: "03-auth.", plan: "02" }          <- greedy (\S+), both wrong

#4594 reports only the phase half. Measured against a real phase-plan-index
run, plans[].id is phase-prefixed, plan-numbered AND slugged, while the prose
carries a bare in-phase plan number — so the plan field mismatches too, and the
Claude path is dead rather than latent. A fresh sentinel was therefore
discarded on every executor dispatch and every legitimate ISOLATION=none
degrade was denied, leaving the work unrun.

hooks/lib/dispatch-identity.js is now the single owner of both halves. The two
prompt-body producers emit a canonical marker carrying the same shell values
the sentinel records, so producer and consumer agree by construction. The prose
frame stays as a fallback, bounded by the phase-token grammar ADR-2121 owns and
deliberately reporting no plan — an absent identifier means "cannot compare"
and is safe; a wrong one is a false mismatch and is not.

The prose sentence itself is byte-identical: the executor agent reads it too,
so the marker is purely additive (Hyrum's Law).

An inapplicable sentinel is now named in the guards' deny reason instead of
being dropped silently — the silence is why this survived three producers and
two consumers unnoticed. Interpolated values come from a sentinel file and from
prompt text, so both are length-bounded and stripped of control characters.

ADR-4630 locks the seam and maps the epic's three phases.

* fix(#4594): resolve eight review findings across the dispatch-identity seam

Three orthogonal review engines ran on 43418af144 — the code-review skill's
Standards and Spec axes, and an isolated adversarial security pass — plus a
self-review of the committed diff. Every finding is fixed here; none deferred.

F1 (major, reproduced). A keyless or unknown-key-only marker — the literal
"[gsd:dispatch]" or "[gsd:dispatch run=..]" — matched the marker grammar and
returned source:'marker' with both fields null, suppressing the prose fallback
entirely. Any prompt text containing that literal silently disabled identity
narrowing, so a fresh sentinel applied to a dispatch it was never scoped to,
defeating #3045 SECURITY F2. Prompt text is attacker-influenceable. A marker
that yields neither recognized key is no longer a marker: the scan continues to
later markers, then later texts, then prose. Forward-compatible tolerance of
unknown keys is unchanged.

F2/F3 (major). The first cut duplicated sanitizeForReason,
describeSentinelDiscard and REASON_INTERPOLATION_MAX_LEN byte-for-byte across
both guards — the exact defect class this epic exists to delete, and with no
cold-load justification, since both hooks already require hooks/lib/. They now
live in hooks/lib/isolation-deny-reason.js, and buildSentinelDiscard lives in
isolation-sentinel.js beside the comparison it mirrors, returning the nested
{sentinel:{phase,plan}, dispatch:{phase,plan}} shape instead of a bespoke
four-field bag that renamed the pairs already flowing through the seam.

F4 (hard violation). The visibility test asserted on the deny reason's prose.
CONTRIBUTING.md prohibits raw text matching on hook output, which is why every
deny carries a stable reason_code. The discard is now a structured
sentinel_discarded field on each hook's stdout JSON, and the test asserts that;
the sentence stays for the operator but is no longer the contract.

F5 (hard violation). The 64-character truncation limit had no boundary
coverage. 63/64/65 are now exercised against the single consolidated helper.

F6 (minor). sanitizeForReason stripped C0/C1 controls but not U+2028/U+2029 or
the bidi overrides, so a crafted value could still reflow or reverse the
message. Both classes are stripped, with a test each.

F7 (major). The producer/template parity test was vacuous — it rendered a
marker and re-parsed its own output, and would have passed with both templates
deleted. It now reads the two workflow templates, extracts each marker line,
substitutes the measured values and asserts the owner's parser returns them.
Proven red by deleting one template's marker line before being proven green.

F8 (doc). ADR-4630 and the design notes claimed the marker is guaranteed on the
orchestrator-worktree path because that prompt is built in shell. It is not:
executor-isolation-dispatch.md:131 says plainly that those are template
placeholders, not shell variables, so {plan_id} is model-substituted there too.
A false guarantee in a design lock is worse than a stated limit. Both documents
now say the marker is model-substituted on both paths and that the prose
fallback is the real floor everywhere. The "3 workflow templates" count was
also wrong — 3 prose sites across 2 files, 2 of which carry the marker.

* chore(#4594): refresh the compact-content baseline and acknowledge execute-phase.md growth

Refs #4630.

The dispatch-identity marker and its substitution note grew
gsd-core/workflows/execute-phase.md by 525 bytes (91846 -> 92371), which drifts
two real-tree guards that lint:ci does not run:

- tests/benchmark-compact-content.test.cjs asserts the committed baseline is
  "up to date"; the split for execute-phase.md moved off 25827 -> 25952 and on
  23576 -> 23701, taking its compaction reduction 8.72% -> 8.67%. Baseline
  regenerated with scripts/benchmark-compact-content.cjs --write.
- tests/emitted-attribution.test.cjs requires a growth acknowledgment trailer
  for any emitted file that grows, keyed on the bare filename. Added below.

The growth is two additions and no rewrites: the [gsd:dispatch ...] marker line
inside the Agent() prompt's <objective>, and the note telling the orchestrator
to substitute {plan_id} with the plan's id verbatim. Both are load-bearing --
the marker is what lets a guard hook match a dispatch to the sentinel the
per-plan gate wrote, and without the note the orchestrator has no instruction
telling it the value must not be paraphrased.

Emitted-Drift-Ack-Growth: execute-phase.md — adds the canonical [gsd:dispatch] identity marker and its {plan_id} substitution note, which the isolation guards compare verbatim against the run-scoped sentinel (#4594)

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.
  • Proposed means 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 to Accepted, each carrying a dated Ratification section with the evidence (see ADR-857 for the fullest example). The ADRs that remain Proposed are Proposed for 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 stale Proposed.

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.md references 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.

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 becomes Superseded.
  • 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.

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 at 0001-alpha.md fails 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:

  1. The decided mechanism demonstrably exists in the tree — name the files, symbols, and tests.
  2. The owning issue is closed as completed. A closed issue is not proof: stateReason of not planned / duplicate means the decision was dropped (that is Legacy or Retired, not Accepted).
  3. 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.
  4. 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.

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).
