9410f7e6e6 enhance(#3897): ADR-3473 §8.3 rungs 2-4 — runtime marker, derived Codex sandbox, short-form depends_on (#3941)
* test(#3897): failing-first coverage for §8.3 rungs 2-4

ADR-3473 §8.3 has four rungs; #3883/PR #3896 shipped the first. This pins the
other three RED before any fix.

Rung 2 — the install marker has four readers and resolveRuntime is not one.

  resolveRuntime resolves GSD_RUNTIME > config.runtime > 'claude' and reads no
  marker at all, while bin/install.js writes one (#2297) and FOUR hand-rolled
  readInstallRuntimeMarker copies exist: src/model-resolver.cts:65 (cached, with
  test seams), hooks/gsd-agent-isolation-guard.js:112, and TWICE in
  hooks/gsd-cursor-subagent-start.js at :346 and :355. Four copies of one rule.

  Fixtures and seam names mined from PR #3382 rather than re-derived; it
  implemented this rung and was closed "not on the merits".

Rung 3 — the sandbox map, and the fallback that was the real defect.

  Measured across all 35 files in agents/, deriving workspace-write iff tools:
  declares Write or Edit:

    - all 11 CODEX_AGENT_SANDBOX entries derive to their mapped value exactly,
      zero disagreements — the map carries nothing the contract does not
    - 24 roles fall through `|| 'read-only'`, of which 16 declare Write or Edit

  So the map is redundant and the silent fallback is the defect. The maintainer
  chose to derive but hold those 16 at read-only pending the question of whether
  Codex enforces sandbox_mode or merely advises; HALT.md records it.

  T20 asserts the emitted sandbox_mode PER ROLE against a captured baseline, not
  in aggregate — an aggregate passes while one role silently widens, which is
  the proxy-instead-of-identity shape this repo names. T24 and T25 fail on a
  stale hold, so the hold list cannot rot into the subset map being deleted.

Rung 4 — shortFormToId, recovered rather than invented.

  I nearly reported this as another wrong §8.3 claim: `git log -S shortFormToId`
  returns only documentation commits. That was the wrong instrument. Direct
  inspection of sdk/src/query/phase.ts at 11918dcc3^ shows five occurrences, and
  the tests match that code rather than a guess at its semantics — including
  first-write-wins on a duplicate short form.

  T43 asserts at the consumer's output: the emitted `waves` map from the real
  CLI, which pre-fix collapses to {"1":[...]} because every short-form edge is
  dropped. A unit assertion on resolveDependencyId would have passed throughout
  this defect's life.

Observed RED, this tree:
  rung 2   11/11 fail — no marker rung, no seams
  rung 3   T23,T24,T25,T26,T30 fail; T28 fails (validate agents passes a TOML
           whose sandbox_mode disagrees — it checks presence only)
  rung 4   T42,T44 fail; T43,T49 fail with waves collapsed to a single wave 1

Green and staying green: T20/T21/T22/T27 as captured baselines, #3885's
unresolvable-token warning and wave-verdict suppression, and #3785's
display-mapping passthrough. If the third tier over-reaches, those go red — that
is their job.

Disclosed weakness: T45 (a canonical id with no dash is not short-form indexed)
cannot be isolated behaviorally, because planMap always masks it. It is a
non-crash boundary pin, weaker than the other rows, and is recorded as such
rather than presented as equivalent.

* enhance(#3897): §8.3 rungs 2-4 — one marker reader, a derived sandbox, the third depends_on tier

ADR-3473 §8.3 has four rungs. #3883/PR #3896 shipped the first. These are the
other three.

Rung 2 — the install marker had four readers, and resolveRuntime was not one.

  resolveRuntime resolved GSD_RUNTIME > config.runtime > 'claude' and read no
  marker, while bin/install.js writes one (#2297) and four hand-rolled
  readInstallRuntimeMarker copies existed: src/model-resolver.cts (cached, with
  seams), hooks/gsd-agent-isolation-guard.js, and twice in
  hooks/gsd-cursor-subagent-start.js.

  model-resolver's was already the house idiom, so it was promoted rather than
  replaced: src/runtime-slash.cts now owns it, and model-resolver plus both
  hooks delegate. The hooks reach it through ensureRuntimeBuild(), the seam
  lint-hooks-runtime-build-seam enforces. No import cycle existed - checked
  both directions before moving anything.

  The marker is the THIRD rung: env > project config > marker > 'claude'.

  N1 was checked rather than assumed, and my first reading of it was wrong. A
  marker holding an unknown name comes back essentially verbatim, which looked
  like a validation gap. Measured against the env rung with the same inputs -
  including "../../etc/passwd" and "claude;rm -rf /" - the two are identical,
  because they share resolveRuntimeNameFromCandidates. N1 asks for exactly that,
  and it is met. The residual (the shared normalizer normalizes shape, it does
  not validate against the known-runtime set) is pre-existing on the env rung
  and plausibly deliberate, since a new runtime should not need a code change.
  The marker also does not widen the trust boundary in any real sense: it lives
  inside the install tree beside the code, so anyone who can write it can write
  runtime-slash.cjs itself.

Rung 3 — the map was redundant; the silent fallback was the defect.

  Measured across all 35 files in agents/, deriving workspace-write iff tools:
  declares Write or Edit: all 11 CODEX_AGENT_SANDBOX entries derive to their
  mapped value exactly, zero disagreements. The map carried nothing the contract
  did not already have, so it is DELETED rather than reconciled. What was
  actually broken is `|| 'read-only'`, which silently under-granted 24 of 35
  roles.

  16 of those 24 declare Write or Edit and would widen under derivation. Per the
  maintainer's decision (HALT.md), they are held at read-only pending the
  question of whether Codex enforces sandbox_mode or merely advises. Emitted
  TOML is therefore byte-identical for all 35 roles - asserted per role, not in
  aggregate, because an aggregate passes while one role silently widens.

  The hold list self-invalidates. A hold whose role no longer derives broader
  fails, and so does a hold naming a role with no agents/<name>.md. Without
  that it would rot into exactly the hand-maintained subset map being deleted,
  and this commit's own ledger claim would become false over time. Both cases
  were proved by injecting them and watching them throw.

  Two committed tests asserted the deleted map's existence and contents. They
  were pinning the thing being removed, so the tests moved rather than the
  production code: the 11 role-value pairs survive as a test-local
  PRE_3897_CODEX_AGENT_SANDBOX baseline, and the assertions now drive the real
  derivation against real agents/*.md. The coverage is preserved; only its
  source moved out of production code.

  validate agents gains checkCodexSandboxPosture, mirroring the existing
  checkCodexModelPosture: each installed TOML's sandbox_mode must equal the
  role's expected value, failing with role, expected and found. It previously
  checked file presence and manifest completeness only, so a TOML whose
  sandbox_mode disagreed passed.

Rung 4 — shortFormToId, recovered rather than invented.

  I nearly reported this as another wrong §8.3 claim: git log -S returns only
  documentation commits. Wrong instrument. sdk/src/query/phase.ts at 11918dcc3^
  carries five occurrences, and the implementation here matches that code rather
  than a guess at its semantics - including first-write-wins on a duplicate
  short form, deterministic from the sorted plan order.

  It resolves the bare plan number: depends_on: ["01"] now reaches
  26-01-auth-hardening. That is a control-flow change, not a diagnostic one -
  plans that silently collapsed into a single wave 1 now execute in their
  declared waves, and execute-phase.md consumes those wave values.

  In-phase only, by construction: the map is built from this phase's rawPlans,
  so a same-named short form in another phase does not resolve.

  #3785's display-mapping passthrough and #3885's unresolvable-token warning and
  wave-verdict suppression are untouched and stay green. If the third tier had
  over-reached, those are what would have caught it.

* fix(#3897): close a fail-open I introduced, and wire the posture check to its command

Two blockers from review. Both are mine, and one is a security regression my own
change created.

1. A held role could escape its hold by editing its own frontmatter.

  The Codex install loop set the sandbox identity from the agent's frontmatter
  `name:` field rather than from its filename, so the hold lookup keyed off a
  value the file itself declares:

    deriveCodexSandboxMode('gsd-doc-writer',   <real file>)          -> read-only
    deriveCodexSandboxMode('gsd-doc-writer-x', <same file, name: edited>) -> workspace-write
    deriveCodexSandboxMode('GSD-Doc-Writer',   <same file, name: recased>) -> workspace-write

  What makes this a blocker rather than a nit is the DIRECTION. The deleted
  CODEX_AGENT_SANDBOX map had the identical lookup-key quirk, but it was an
  allowlist: an unmatched key fell back to read-only, which is safe. The new
  scheme derives workspace-write from the tool contract and uses the hold as a
  subtraction, so the same mismatch fails OPEN. I converted a fail-closed quirk
  into a fail-open one and did not notice; the isolated reviewer proved it by
  execution.

  Neither safety net caught it. validateCodexSandboxHolds only checks that
  <key>.md exists, never that a file's derived identity matches its key.
  checkCodexSandboxPosture looks the canonical source up by the installed TOML's
  filename, finds nothing for a renamed agent, and treats it as a custom
  non-roster agent — silently no violation.

  The identity is now the FILENAME STEM, which is what validateCodexSandboxHolds
  already validates and what an attacker editing frontmatter cannot change
  without renaming the file — at which point the existing validator catches it.
  The lookup is case-insensitive so a recase does not slip past either. The
  frontmatter name still drives the TOML body and filename, unchanged; only the
  sandbox identity moved.

  All 35 roster files were checked: name matches filename stem everywhere, so a
  stricter "they must agree or throw" invariant would have been safe against real
  content. It is deliberately NOT added — it would abort an install on a tampered
  file where emitting a correctly-derived read-only TOML is the safer outcome.
  Recorded as a fork rather than decided silently.

2. checkCodexSandboxPosture was exported and never called.

  cmdValidateAgents (src/verify.cts) called checkAgentsInstalled and
  checkCodexModelPosture only; grep for the sandbox check in that file returned
  nothing. So criterion 3 — "validate agents fails on semantic drift, not only on
  missing files" — was unmet, and `validate agents` behaved exactly as before.
  That is ADR-3473 Decision 2's named shape: a declared policy with no executor.

  It also meant the T28 test asserted at the helper's return value while the
  COMMAND stayed broken — the ADR-3180 Decision 4(b) failure this epic exists to
  close, committed by me while enforcing it elsewhere in the same epic.

  Now wired as an additive `sandbox_posture` field beside `codex_posture`,
  following the sibling precedent exactly. Drift is report-only, not a non-zero
  exit, because that is what checkCodexModelPosture does — two sibling posture
  checks disagreeing about whether a violation is fatal would be its own defect.
  The choice is recorded in a comment rather than left implicit. A consumer-output
  test now drives the real CLI and asserts on the emitted JSON, and was shown
  failing before the wiring and passing after.

Also corrected a stale artifact: the design's Known limit L1 still claimed rung 3
was not in this deliverable, written while it was halted and false once the
maintainer unblocked it.

Verified after both fixes: the three bypass probes all return read-only, the
per-role table is 35/35 byte-identical, and both hold self-invalidation cases
still throw.

* docs(#3897): the marker rung, the derived sandbox, and the bare plan-number depends_on

Reference: the runtime precedence ladder in docs/CLI-TOOLS.md gains the install
marker rung; docs/COMMANDS.md documents validate agents' new sandbox_posture
field; docs/reference/plan-md.md documents that depends_on accepts the bare plan
number.

Explanation: a docs/features fragment keyed id 3897, so it cannot collide with a
concurrent PR hand-allocating a section number, regenerated into FEATURES.md.

ADR-3473 §8.3 gains an ANSWER blockquote in the document's own correction style,
recording what was measured and built against the section's 2026-08-26 correction
- including the qualification that checkAgentsInstalled itself still checks
presence only, and the semantic assertion lives in a sibling wired into validate
agents rather than folded into it.

No how-to. Both user-visible changes are zero-step: a non-Claude install resolving
its own runtime, and plans executing in their declared waves, both happen without
the user doing anything. docs/how-to/control-the-reported-host-runtime.md covers a
DIFFERENT ladder (resolveReportedRuntime / agent_runtime) that this change does
not touch, and was deliberately left alone rather than edited by association.

No tutorial - nothing multi-step to walk through. docs/AGENTS.md unchanged: it
documents Claude-side tools frontmatter, never Codex sandbox_mode, and the
emitted tools contract did not change.

The prompt layer documents depends_on only by example, not by schema, so nothing
there needed editing - and few-shot-examples/plan-checker.md already showed
depends_on: ['01'], which now actually resolves.

Translated copies of plan-md.md are untouched; the project treats translations as
community-maintained.

* fix(#3897): move the sandbox derivation out of the installer, off the install path, and off a third parser

The full suite came back with 26 failures across four files. Three distinct
causes, mapped individually rather than assuming the first explained the rest.

A. Requiring bin/install.js printed the GSD banner to stdout and corrupted
   `validate agents` JSON.

     Unexpected token '', "[36m   ██"... is not valid JSON

   checkCodexSandboxPosture reached deriveCodexSandboxMode by lazily requiring
   bin/install.js, whose module load prints the ASCII banner. So the command
   emitted banner bytes before its JSON and every JSON consumer broke, including
   ten tests that predate this branch. src/ reaching into bin/ was backwards
   layering that happened to also be loud.

   The derivation now lives in src/codex-agent-toml.cts - the existing Codex TOML
   domain module, no new module and no six-gate ripple - and both bin/install.js
   and src/agent-install-check.cts import it. One owner, which is §8.3's rule
   applied to the fix for §8.3.

B. The stale-hold throw fired on a legitimate partial source dir, and masked a
   security assertion.

   validateCodexSandboxHolds treated "this hold's .md is absent from the install
   SOURCE dir" as a stale hold and threw. A test fixture, or any partial install
   source, legitimately contains a couple of agents. Worse, it threw BEFORE the
   path-escape check, so a test asserting that a `../../evil` frontmatter name is
   rejected got my unrelated error instead of the traversal rejection it was
   written for. A fail-closed check of mine was hiding a real security check.

   The "no stale holds, shrink-only" invariant is a property of the repo's
   canonical agents/ roster, not of whatever directory an install happens to read.
   It is off the runtime path and enforced where it belongs, in the tests that
   already existed for it. A partial source dir now installs cleanly, and the
   evil-name case throws with its own escapes-configHome message again.

C. T8 depended on ambient process.env state.

   The marker/env parity assertion round-tripped through live process.env. It now
   compares against resolveExplicitRuntime's already-exported dependency-injection
   parameter - deterministic and hermetic, same claim. Proven still falsifiable
   rather than assumed: with the marker rung's normalization temporarily bypassed
   the two rungs diverge ("codex\n../../etc/passwd" vs "codex-../../etc/passwd")
   and the assertion fails, then passes again once reverted.

One correction folded in along the way. The first version of the move added
private _extractFrontmatterAndBody/_extractFrontmatterField helpers to
codex-agent-toml.cts - a THIRD copy of frontmatter extraction, where the graph
already shows two (bin/install.js:2348, runtime-artifact-conversion.cts:893).
Adding a third inside the epic whose thesis is one implementation per rule is not
defensible. deriveCodexSandboxMode no longer parses anything: it takes
(identity, toolsValue) and each caller supplies the tools value using the
extractor it already has. Both helpers are deleted. The identity argument is
still the filename stem, so the fail-open fix is untouched.

Verified after all three: `validate agents --raw` emits parseable JSON with no
banner and both posture fields; the four hold-bypass probes still return
read-only; the per-role table is 35/35 byte-identical at 26 read-only / 9
workspace-write; the hold list is still 16.

* fix(#3897): drop a dev-only transitive dep, make the derivation total, retire a stale fallback test

Suite down to 7 failures from 26. Three more causes, mapped individually.

A. My extractor import dragged in a script that does not exist in an installed
   tree.

     Cannot find module '../../../scripts/fix-slash-commands.cjs'

   Chain: src/agent-install-check.cts imported runtime-artifact-conversion.cjs,
   which requires command-roster.cjs, whose line 36 requires
   ../../../scripts/fix-slash-commands.cjs. That path exists in the repo and not
   in an install, so every test exercising a synthetic install dir died at module
   load. I picked that extractor for convenience without checking what it pulls
   in - the same mistake that produced the banner bug, one layer further out.

   agent-install-check now uses a single-purpose extractToolsLine on
   codex-agent-toml.cts. That is deliberately NOT a general frontmatter parser:
   we deleted those helpers a commit ago for good reason, and this reads one
   line. Verified from outside the repo root that requiring either module prints
   nothing and does not throw.

B. A test pinned the deleted name-based fallback.

   'defaults unknown agents to read-only' called generateCodexAgentToml with a
   fixture declaring tools: Read, Write, Edit. Under derivation an unknown agent
   with a writing contract correctly derives workspace-write - design row S6, a
   new writing role gets the contract, not the pin. The behavior it asserted was
   the silent fallback this rung deleted; identity no longer decides the sandbox.

   Replaced with two rows rather than a flipped string: no tools declared ->
   read-only (absence is not a grant), and Write/Edit declared -> workspace-write.
   Strictly more coverage than the row it replaces.

C. The stale-hold check still threw per derivation call.

   Last commit took the roster-existence check off the install path, but
   deriveCodexSandboxMode itself still threw when a hold's role did not derive
   broader FOR THE CONTENT IT WAS HANDED - so it fired on any synthetic fixture
   for a held role.

   The throw is gone, and it cost nothing: if a held role's content does not
   derive broader, the hold pins read-only and derivation returns read-only
   anyway, so the hold is a no-op and there is nothing to fail about. The
   staleness invariant is a property of the real agents/ roster, and
   validateCodexSandboxHolds still enforces it there - confirmed against the real
   roster after the change, not assumed.

   deriveCodexSandboxMode is now total: every (identity, toolsValue) including
   undefined and null returns read-only or workspace-write, never throws.

Verified: validate agents emits parseable JSON; the four hold-bypass probes
return read-only; the per-role table is 35/35 at 26 read-only / 9
workspace-write.

* docs(#3897): put the rung-3 decision in the shipped docs instead of pointing at an ignored path

The ADR entry and the feature fragment both ended their rung-3 explanation with
"see .gsd/phase/feat-3897-adr3473-83-rungs/45-decision-rung3-sandbox.md". That
directory is gitignored (.gitignore:55), so the rationale for holding 16 roles at
read-only was reachable only from the machine that produced it. A reader of the
ADR got a pointer to nothing.

Both now carry the reasoning inline: the criterion asks both that the sandbox
derive from the declared tool contract and that no role gain a broader sandbox,
and those cannot both hold, because a faithful derivation widens 16 roles the
deleted map never listed and that fell through its silent read-only default. The
resolution is derive-and-hold - the derivation owns the rule now, each hold is
released as its enforcement question is answered, and a hold is reversible where
a widened sandbox that turns out to be enforced is not.

Checked before assuming this was a defect class: CONTEXT.md cites
.gsd/phase/<slug>/40-design.md as its standard Design: provenance line in eight
module entries, and four other shipped docs do the same. Citing a phase artifact
is an established convention here, so those are left alone. What was wrong was
specific to these two: they put load-bearing rationale behind the pointer instead
of provenance.

docs/FEATURES.md regenerated from the fragment via scripts/gen-features.cjs
rather than hand-edited.

* fix(#3897): close a fail-open, stop a silent mis-resolution, and read a declaration as a declaration

Two orthogonal reviews on the shipped sha. Three of the findings are the same
failure class this epic exists to close, committed inside it.

1. BLOCKER - the sandbox was decided for one identity and applied to another.

   bin/install.js derived sandbox_mode for the filename stem and then wrote the
   result to `${name}.toml`, where name comes from the file's own frontmatter.
   Make the two disagree and a HELD role's artifact goes wide:

     rename gsd-doc-writer.md -> gsd-doc-writer-v2.md, keep name: gsd-doc-writer
       -> stem is unheld, derives workspace-write, lands on gsd-doc-writer.toml
     add any gsd-*.md whose frontmatter name: is a held role
       -> clobbers that role's toml with workspace-write

   Both emit read-only on origin/next, because the deleted map was an allowlist
   and a miss fell back safe. This is a regression my change introduced. The
   previous review round moved the HOLD KEY off frontmatter to the filename stem
   and left the OUTPUT PATH on frontmatter; my own comment at install.js:6985
   calls that value attacker-editable, four lines above the line that uses it as
   the filename.

   The decision is now made over BOTH candidate identities, most-restrictive
   wins: if either the stem or the emitted name is held, the mode is read-only.

2. MAJOR - hold matching was toLowerCase() only, so confusables escaped.

   Turkish dotted/dotless i, fullwidth, NFD, trailing space/NBSP/dot/newline,
   ./ and ../agents/ all slipped the hold and emitted workspace-write.
   Identities are now basenamed, trimmed of NBSP/zero-width/control characters,
   NFKC-normalized and lowercased - and anything still carrying a character
   outside [a-z0-9._-] is treated as suspicious and derives read-only. We do not
   enumerate confusables; every shipped roster file is ASCII, so refusing to
   widen on an identity we cannot recognize is fail-closed with no false
   positives on real content.

3. MAJOR - the short-form depends_on tier mis-resolved SILENTLY.

   shortFormToId keyed on the last dash-segment of any canonical id with no
   constraint that it is a plan number, so a phase holding 09-FIX-auth-PLAN.md
   made depends_on: ["auth"] bind at wave 2 with zero warnings. This is the
   worst shape in the epic: the unresolvable-token warning fires on a DROPPED
   token, so a MIS-RESOLVED one is invisible and the tool reports a confident
   wave assignment built from a wrong edge. A wrong edge is worse than a missing
   one.

   The segment must now match /^\d+$/, which is exactly the contract
   docs/reference/plan-md.md already documents. This tier was recovered verbatim
   from the retired SDK lineage, which carried the same defect; we are
   deliberately NOT preserving it bug-for-bug, and the comment says so, so the
   next reader does not "restore" it.

4. MAJOR - the derivation was reading a declaration as an absence.

   extractToolsLine read one line, so a YAML list-form tools: block returned only
   its first item. Two roster files use list form, and gsd-nyquist-auditor
   declares Write and Edit there - parsed as "- Read", found no write tool, and
   emitted read-only. Rung 3's headline claim is that sandbox_mode derives from
   the declared tool contract; that claim was false for 2 of 35 roles and
   materially wrong for 1. Reading a declaration as an absence is the silent-drop
   class this epic exists to close.

   Renamed extractToolsValue and taught it both shapes. gsd-nyquist-auditor now
   derives workspace-write and joins CODEX_SANDBOX_HOLDS as its 17th entry, per
   the standing derive-and-hold decision - so emitted TOML stays byte-identical
   at 26 read-only / 9 workspace-write while the hold list finally records every
   role that would widen. A previous pass declined this fix because it moved the
   count; that inverts the priority. Byte-identity is preserved THROUGH the hold,
   not by leaving a parser broken.

   Divergence check, because this is where that bug hides: both paths feeding
   sandbox derivation - install.js's emitter and checkCodexSandboxPosture - now
   route through the one extractor. The tools readers in
   runtime-artifact-conversion and install.js's other frontmatter call sites
   serve Claude-side emission and do not feed sandbox derivation.

Also fixed, each real: the posture check's `found` used a naive whole-file regex
where its own sibling uses the block-aware scanner, so prose inside
developer_instructions produced a false violation; `found` skipped
truncatePostureValue and leaked a 300-char value into validate agents output;
deriveCodexSandboxMode's absolute never-throws claim was false for an object with
a throwing toString; T49 could not falsify cross-phase leakage (its target phase
had its own 01, so a globally-scoped map passed too); T20/N6 iterated a hardcoded
table and pinned the FIXTURE size, so a 36th agent would be silently unchecked;
three tests reimplemented the code they were testing instead of importing it; and
T2-T4 deleted GSD_RUNTIME without restoring it.

Verified: hold list 17, gsd-nyquist-auditor derives workspace-write unheld and
emits read-only held, roster 35/35 at 26/9, depends_on ["auth"] no longer
resolves while ["01"] still does, both identity-bypass cases and every confusable
vector emit read-only.

* docs(#3897): the hold list is 17, and the reason the 17th was missing

The count read 16 because the derivation could not read the declaration it
claimed to derive from: the tools reader was single-line, so a YAML list-form
tools: block returned only its first item and gsd-nyquist-auditor's declared
Write and Edit were read as an absence.

Both the ADR entry and the feature fragment now carry the corrected count and the
reason for it, rather than a silently updated number. Deriving from a declaration
you cannot parse is not deriving, and a flattering count is worse than a wrong
one because it looks settled.

docs/FEATURES.md regenerated from the fragment.

2dbee3ebdd enhance(#2229): add three-way claim disposition (admit/refute/abstain) to /gsd-explore research pass (#2543)
Closes #2229.

Each claim surfaced by /gsd-explore's research pass is dispositioned admit, refute, or abstain, with abstentions routed to a visible ledger instead of being smoothed into confident prose. Refute and abstain are separated by whether the disagreeing source is authoritative for that claim; a strong prior is never authoritative alone.

Two guards ride with it: conflict-abstention, and a tier floor that presents a would-be admit as an abstain when the researcher's resolved tier is the budget tier or cannot be determined.

To make that floor enforceable, resolve-model now emits the effective tier (--pick tier). It was already computed above the resolve_model_ids omit gate but was unreachable from a workflow, which left the floor inert on every non-Claude install - the model id is blank under omit and runtime-substituted where a tier map exists, and the profile defaults to balanced. The tier signal mirrors every resolution step that can change which tier runs, including the model_policy preset, and reports unknown rather than guessing. Output is additive; model, profile and effort are unchanged.

Two residuals are disclosed in the workflow rather than papered over: a raw-model-id model_overrides pin reports unknown and is floored (fails closed), and a model_profile_overrides entry repointing a tier at another tier's model can under-report (fails open, and predates this change).

Admin merge used only to satisfy the missing secondary reviewer on a single-maintainer PR. No CI failure and no conflict were bypassed: 38 checks green, remote runner 32255/32255 on both Node lanes.

58d73dd220 enhance(#3241): omit the codex per-agent model by default (#3276)
* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

min(max_escalations, list length) at limit-1/limit/limit+1, opt-in gating,
malformed/hostile provider_escalation config, the --failure-class CLI negative

* feat(#2296): config-gated provider escalation on quota-exceeded

The dynamic_routing tier ladder escalates within one provider, which does not
help when that provider is what ran out of quota. Add an opt-in provider ladder
layered on the existing EXEC.CLASSIFY seam.

- model-resolver: resolveProviderEscalation walks dynamic_routing.provider_escalation
  capped at min(max_escalations, list length), reporting from/to/attempted/exhausted.
  Invalid entries are dropped (ADR 227 shape validation). Stays a leaf module —
  the quota-class policy decision is the caller's, per the CONTEXT.md contract.
- agent-command-router: export a frozen AGENT_FAILURE_CLASSES so the new CLI
  validator cannot drift from the classifier that produces the values.
- resolve-execution: --failure-class flag; emits an escalation block ONLY when
  passed, so the existing JSON contract is byte-identical for every caller.
- config-schema.manifest: register dynamic_routing.provider_escalation.
- execute-phase step 7.1: auto-escalate, honor Retry-After, fail loudly naming
  every model tried once the ladder is spent.

* fix(#2296): extract quota recovery to a reference fragment; regen goldens

The step 7.1a addition pushed gsd-core/workflows/execute-phase.md from 93390 to
95111 LF bytes, past the frozen ADR-857 Phase 6 ceiling (hard <93600, margin
<=93400) asserted by tests/fix-2285-claude-orchestration-wiring.test.cjs. The
base sat 10 bytes under the margin, so no inline wording would have fit.

That gate's own rationale is that optional-feature detail belongs in a fragment,
not the host loop. Moved BOTH the new provider-escalation branch and the
pre-existing manual recovery prompt into
gsd-core/references/execute-phase-quota-recovery.md, leaving step 7.1 as a
one-line pointer. execute-phase.md is now 92880 bytes — 510 SMALLER than base.

Also regenerates the fixtures that legitimately moved because three shipped
files changed (gsd-tools.cjs, config-schema.manifest.json, execute-phase.md):
golden-install-parity + install-tree for all 16 runtimes, INVENTORY.md +
INVENTORY-MANIFEST.json for the new reference, and the workflow size baseline.

* test(#2351): make the C1 orphan-reaping test load-independent

tests/run-with-timeout.test.cjs C1 asserted the child heartbeat file exists
after a 1s group-kill window, but the child only wrote it on the first 100ms
setInterval tick. Nothing synchronized the two: on a loaded container the group
is SIGKILLed before that tick lands, the file never appears, and the assertion
fails for a reason unrelated to reaping. Observed failing on both linux-node22
and linux-node24.

The behavior actually under test is the FREEZE assertion (heartbeat stops
advancing => descendant was reaped, not orphaned). That is unaffected by
sampling once more at t=0.

Child now writes its first heartbeat synchronously at startup before arming the
interval, and the kill window widens 1s -> 3s to cover child boot under load.
Both remove the timing dependency; neither weakens what the test proves.

resolved content was stale and would have dropped #2402's fixture changes.

* test(#2070): fail-first tests for adaptive model_profile and models tier validation

Encodes the three acceptance criteria from #2070 plus the boundary cases the
resolver silently ignores today (non-string values, empty string, mistyped
phase-type key), and pins VALID_TIERS to a catalog-derived set.

Red phase: these fail against current src/ by design.

* fix(#2070): accept adaptive model_profile in validate health; warn on invalid models tiers (W022)

W004 sourced its profile list from a hand-maintained literal that predated the
adaptive profile, so `"model_profile": "adaptive"` was false-flagged. It now
reads VALID_PROFILES, which model-catalog.cts derives from model-catalog.json.

models.<phase_type> was validated nowhere: the resolver's tier gate silently
drops unknown values, so a typo like `"planning": "opuss"` was an undiagnosable
no-op. A new W022 flags unknown phase-type keys and invalid tier values
(including non-string values, which the same gate also drops).

VALID_TIERS moves from a function-local literal in model-resolver.cts to a
catalog-derived export, so health and the resolver cannot disagree by
construction rather than by parity test. Object.values(adaptiveTierMap) is
['opus','sonnet','haiku'] plus 'inherit' — identical to the previous literal,
so resolution behavior is unchanged.

Claude-Session: https://claude.ai/code/session_01SLufH5sDuqA1AiEGu45cuA

* fix(#2070): close review findings — malformed models, tier-list duplication, changeset gate

Review of the initial fix surfaced three real defects, folded in per the
no-defer rule:

1. verify.cts: the W022 guard skipped a top-level `models` that is present but
   not a plain object (`[]`, `"opus"`, `5`, `true`). The resolver ignores those
   identically, so they were the same undiagnosable no-op #2070 targets — just
   one level up. They now warn; absent/null/{} stay silent.

2. config-loader.cts: RUNTIME_OVERRIDE_TIERS was a second hardcoded copy of the
   tier vocabulary this change had just de-hardcoded elsewhere. It now derives
   from the catalog via ADAPTIVE_TIER_VALUES (no 'inherit' — runtime overrides
   resolve to a concrete tier). Byte-equivalent to the old literal.

3. scripts/changeset/lint.cjs: USER_FACING_PREFIXES omitted `src/`. Post-ADR-457
   the product source is src/*.cts compiled to a gitignored gsd-core/bin/lib,
   so the `gsd-core/` prefix is dead coverage for library code and a src/-only
   PR could merge with no release note — including this one. Adding `src/`
   closes the gate; tests/ stays non-user-facing.

Also corrects a false docstring in the VALID_TIERS test: value-equality cannot
detect a re-hardcoded literal, so the test no longer claims it does.

Two review findings were rejected with evidence rather than actioned:
- W021 double-allocation is governed by ADR-612 ("W021 renumber -> void ...
  kept, message-disambiguated"), not a defect.
- Global-defaults validation would be a false-positive generator: config-loader
  reads ~/.gsd/defaults.json only on the "no .planning/" branch, and health
  early-returns E001 without .planning/, so those values provably never affect
  resolution in any context health can run.

9ad2bab4be fix(#2297): scope resolve_model_ids:"omit" to the resolving runtime (#2332)
* fix(#2297): scope resolve_model_ids:"omit" to the resolving runtime

The installer writes resolve_model_ids:"omit" for non-alias runtimes into the
machine-wide ~/.gsd/defaults.json (#1156); any runtime read it back, so install
order silently flipped Claude's adaptive tier aliases (executor->sonnet,
planner->opus) to '' in no-project sessions.

Resolution is now scoped to the runtime actually resolving, identified by a new
per-install <install>/gsd-core/.gsd-runtime marker (installer writes it beside
VERSION). The "omit" branch returns '' only when the PROJECT explicitly set omit
(honored for all runtimes, #2517 finding #4) OR the active runtime lacks native
aliases. Claude ignores a global-defaults-only omit and keeps its aliases; the
active runtime is canonicalized (GSD_RUNTIME -> config.runtime -> marker ->
claude) so alias/case spellings can't defeat the check; explicit project
omit is workstream/project-scope aware; explicit true still materializes IDs.

a22333034b fix(#2310): guard Codex agent model_overrides so Anthropic aliases never leak into .toml (#2312)
* fix(#2310): guard Codex agent model_overrides so Anthropic aliases never leak into .toml

generateCodexAgentToml embedded a per-agent `model_overrides` value verbatim as the
Codex `.toml` `model`, leaking GSD/Claude tier aliases (opus/sonnet/haiku/fable) and
`claude-*` ids. Codex/ChatGPT rejects those (400 "The 'sonnet' model is not supported
when using Codex with a ChatGPT account"), and since spawn_agent has no inline model
param, the model is baked into the .toml at install time — so the orchestrator could
not recover and fell back to the non-equivalent generic-agent workaround.

Translate a GSD tier alias through the Codex tier map (sonnet -> gpt-5.6-terra); drop
with a deduped warning any Anthropic-flavored value with no Codex mapping (fable) or a
`claude-*` id, so emission falls through to the runtime-aware resolver or Codex's
default. A final safety gate blocks an Anthropic-flavored model from the runtime-
resolver path too (runtime/target mismatch). Mirrors the Claude-side override guard
(#2041). Real Codex/OpenAI model ids in model_overrides still pass through verbatim
(#2256 preserved); runtime:"codex" tier resolution unchanged (#2517).

Adds regression + fast-check property tests in tests/codex-config.test.cjs.

* fix(#2310): Codex passive-model posture — omit Anthropic-flavored model (all namespacings)

Adopt ADR-1239's passive/session-only posture for Codex model handling: a Codex
agent .toml `model` is embedded ONLY for an explicit real-Codex model_overrides
pin; any Anthropic-flavored value is omitted so the agent inherits the always-
available session model (never a 400).

- model_overrides tier alias (opus/sonnet/haiku/fable) or a Claude model id →
  omit (was: translate to gpt-*); an explicit real-Codex model id → embed
  verbatim (#2256 preserved).
- Detect ALL Anthropic namespacings, not just `claude-*`: single-source the
  canonical CLAUDE_AGENT_ALIASES from model-resolver.cts and treat any id whose
  value contains "claude" (case-insensitive) as Anthropic-flavored — catching
  `anthropic/claude-*` and `us.anthropic.claude-*` (the forms the catalog assigns
  to opencode/hermes/kilo), which reach a Codex .toml via the runtime-resolver
  path on a mixed-runtime + Codex install.
- The final safety gate applies to the runtime-resolver path too.

The full passive posture (removing #2517's runtime-resolver per-tier embedding +

e95af39a8c fix(#2041): address code+security review findings
- add typeof guard so a non-string override passes through verbatim instead of
  crashing on .startsWith (preserves pre-fix no-crash behaviour) [LOW-1]
- use Object.hasOwn() for the alias lookup so __proto__/constructor cannot
  return a truthy non-string from the plain object literal [LOW-D3]
- cap the unmappable-override stderr warning at 64 chars so an oversized or
  secret-shaped value cannot leak in full to stderr/logs [LOW-D4]
- remove the unused mapClaudeOverrideForRuntime export (helpers are covered
  behaviourally via resolveModelInternal/resolveModelForTier) [NIT]
- add resolveModelForTier unmappable-override fall-through test (closes the
  mutation-score gap) [MEDIUM-1]
- add case-sensitivity contract test (Claude-Sonnet-5 passes through verbatim) [LOW-2]

Both orthogonal reviews returned APPROVE with no Critical/High findings.

f214f1320d fix(#2041): map model_overrides full claude IDs to agent-tool aliases
model_overrides values that are full Claude model IDs (claude-sonnet-5,
claude-opus-4-8, claude-haiku-4-5, claude-fable-5) were returned verbatim on
the claude runtime and handed to the Claude Agent tool, whose typed model
parameter documents only tier aliases (opus/sonnet/haiku/fable). The
model_policy path already mapped full IDs -> aliases via
CLAUDE_POLICY_ID_TO_ALIAS (#1144); model_overrides skipped that mapping, so
the two resolver paths produced different shapes for the same underlying
Claude model. The fix mirrors #1144 on the override path via a shared
mapClaudeOverrideForRuntime helper used by both resolveModelInternal and
resolveModelForTier. Bare aliases pass through verbatim; non-Claude runtimes
and non-Claude custom/vendor values keep full IDs verbatim (parity). An
unmappable Claude ID (e.g. claude-opus-4-5) warns once to stderr and falls
through to tier resolution, exactly as the model_policy path already does.
Alias mapping is also the documented best practice (prevents staleness when
new model versions ship).

8c3d934a90 refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete) (#1295)
* refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete)

After T0–T6 nothing imports core, so retire the spine and its scaffolding:
- delete src/core.cts (and the gitignored gsd-core/bin/lib/core.cjs artifact;
  remove its .gitignore + eslint-ignore entries)
- delete scripts/lint-core-spine-imports.cjs + its allowlist; drop it from the
  package.json lint:ci chain
- regenerate docs/INVENTORY-MANIFEST.json (drops the core.cjs surface)
- sweep stale references: CONTEXT.md glossary back-compat clauses (spine retired,
  callers import the leaf directly), planning-config.md CONFIG_DEFAULTS owner,
  and false present-tense core.cjs claims in leaf-module docstrings

The ADR-857 decomposition is complete: the former Core god-module is fully
dissolved into its leaf modules; no re-export spine remains. No behaviour change.

Closes #1294

* fix(#1294): migrate the computed-path core.cjs importers the literal grep missed

bin/install.js used require(path.join(_gsdLibDir, 'core.cjs')) (a computed
path, and bin/install.js was never in the convergence lint's scan roots), and
~8 test files referenced core.cjs via path.join/readFileSync/existsSync/FILE_ARG
forms the literal-string migration grep missed. Route install.js's symbols to
their leaves (RUNTIME_PROFILE_MAP->model-catalog, resolveTierEntry/EFFORT_SET->
model-resolver) and repoint/adjust the test references to the leaves. Recovers
the 161 'Cannot find module core.cjs' failures from the spine deletion.

44024aa535 fix(#1133): honor model_policy on the claude runtime (forward-port to next) (#1144)
Forward-port of the #1133 hotfix (commit 22f237a5, 1.4.5 hotfix line) onto
next. The hotfix was authored against src/core.cts (v1.4.4); on next the
resolver logic lives in src/model-resolver.cts (ADR-457 extraction, #888),
so the patch is re-applied there rather than cherry-picked.

resolveModelInternal step 2.5 now honors model_policy on the claude runtime:
the policy-resolved full model ID is mapped back to a Claude Code agent alias
via CLAUDE_POLICY_ID_TO_ALIAS (reverse of MODEL_ALIAS_MAP + claude-fable-5 ->
fable). Bare aliases (opus/sonnet/haiku/fable) pass through; an ID with no
Claude alias warns once to stderr (deduped by agentType::policyModel::tier)
and falls back to the configured tier alias. Non-claude runtimes return full
IDs verbatim (unchanged). resolveModelForTier is intentionally unchanged.

The warn-dedupe cache lives in model-resolver.cts; core.cts composes the
exported _resetRuntimeWarningCacheForTests to clear both that cache and the
config-loader warning cache (config-loader cannot import model-resolver --
circular dependency).

Ports the 6 #1133 tests (rewriting the old claude-no-op test that asserted
the bug) plus one added test covering the MODEL_ALIAS_MAP reverse-map path.

Forward-port of #1133

185935379a refactor(#888): extract model+effort resolution into model-resolver.cts (#890)
ADR-857 rollout phase 2f — the FINAL core.cts decomposition. Move the model and
effort resolution cluster (resolveModelInternal, resolveModelPolicy,
resolveTierEntry, _resolveRuntimeTier, resolveModelForTier,
resolveGranularityInternal, assertValidGranularityOverride, resolveEffortInternal,
resolveFastModeInternal, resolveEffortForTier, nextEffort + VALID_GRANULARITIES/
VALID_EFFORTS/EFFORT_SET + interfaces) out of core.cts into a new leaf module
src/model-resolver.cts. core.cts re-exports the 13 public symbols (callers in
init/docs/commands unchanged; export= set byte-identical).

Cycle-free: model-resolver imports only leaves (config-loader for loadConfig,
configuration for defaults, model-profiles + model-catalog for the static
tables). Removed 6 now-unused imports from core (verified zero remaining
references, none re-exported).

This completes the god-module decomposition: core.cts 2271 -> 389 lines (~83%),
now a thin re-export spine over seven clean leaves (io, phase-id, roadmap-parser,
core-utils, phase-locator, config-loader, model-resolver).

New-CLI-module checklist done (.gitignore, eslint, INVENTORY 96->97 + row,
manifest, ARCHITECTURE, CONTEXT.md "Model Resolver Module"). Adds
tests/model-resolver.test.cjs (81 tests: behavioral + shim-identity + adversarial).

Gates: lint, code-review (export set byte-identical; import-removal verified),
security-review, codex adversarial-review (all 0 findings; verbatim move). Mac
4303 pass; clean-build docker 13117 pass, 0 fail.

Closes #888
