Fold CodeBuddy's residual runtime-literal branches onto descriptor-driven
hostBehaviors (the issue's "zero branches remain" premise was inaccurate — 2
lived):
- Folded the `if (isCodebuddy)` commands/ report duplicate (byte-identical to
the generic reportCommandsDir block above it) onto
hostBehaviors.reportCommandsDir:true, matching cursor's #2089 precedent.
- Deleted the dead `else if (isCodebuddy)` agent-conversion arm (codebuddy ∈
_DESCRIPTOR_AGENTS_RUNTIMES → gated out before the legacy chain, same dead-arm
pattern removed for augment/trae in #2097).
- Removed isCodebuddy from all 4 destructure sites (now comments only, mirroring
the #2096 isAntigravity fold). Zero live isCodebuddy reads remain.
UPGRADE 1 (extended hook bus): populate extendedHookEvents with the full
extended set SubagentStop/Stop/PreCompact/SubagentStart (qwen #2092 / kimi
precedent — codebuddy previously had extendedHookEvents:[] so it got NONE of
these). The generic applySettingsJsonHooks loop wires them, so CodeBuddy's
settings.json now gains all four subagent-lifecycle + stop/compact hooks it
previously lacked, matching Qwen/Kimi coverage. No source change (the
HOOK_EVENT_SURFACES SDK catalog is a locked dict; all 4 events are already in
the validator enum; hookEvents already 'claude'). settings.json is golden-
excluded → no golden change.
UPGRADE 2 (background dispatch): surfaced via the negotiated capability contract
only. CodeBuddy's dispatch.background:true legitimately exceeds the declarative-
cli baseline (false) and survives negotiation with no warning. NO agent-file
frontmatter field is emitted: the CodeBuddy CLI (GSD's install target,
~/.codebuddy/agents/) has NO background-dispatch frontmatter field — background
is a caller-side run_in_background invocation param (verified against
codebuddy.ai/docs/cli/sub-agents); the issue's agentMode/enabledAutoRun are
IDE-only (codebuddy.cn, a different product). Emitting them would be a non-
functional false-green, so it is deliberately not done.
Golden: byte-identical for all 16 runtimes (folds are console/failures-report
only; UPGRADE 1 → golden-excluded settings.json; UPGRADE 2 → no artifact
change). Tests: declarative-reference-codebuddy (adapter/axes/fail-closed
negotiation + AC2 source-grep guard) + codebuddy-upgrades (live install asserts
all 4 extended hooks wired; dispatch.background survives negotiation above
baseline). Matrix + install-on-your-runtime updated; changeset (Changed).
capability-registry regenerated.

Fold augment's runtime-literal conversion branches onto descriptor-driven
hostBehaviors and delete dead code:
- Site A (_applyRuntimeRewrites case 'augment'): the 4 ~/.augment dot-dir
regexes now derive from getDirName('augment') via escapeRegExp (byte-
identical; getDirName('augment')==='.augment') — no runtime literal.
- Site B (applyRuntimeContentRewritesForCommandsInPlace): the
`if (runtime==='augment')` markdown-converter branch now reads
runtime.hostBehaviors.commandBodyConverter and dispatches through a local
COMMAND_BODY_CONVERTERS map (degrade-closed on unknown/absent name).
- Deleted dead `claudeToAugmentTools` map (zero refs; orphaned by ADR-1508
single-sourcing) and the unreachable `else if (isAugment)` agent-conversion
branch (augment ∈ _DESCRIPTOR_AGENTS_RUNTIMES → gated out upstream).
- Incidental orphan cleanup (no-defer): removed the equally-unreachable
`else if (isTrae)` agent-conversion arm left behind by trae's already-merged
migration #2094 (trae ∈ _DESCRIPTOR_AGENTS_RUNTIMES, same upstream gate).
copilot/windsurf/codebuddy arms are removed by their own pending migrations.
UPGRADE 3 (transport:mcp): register the GSD companion MCP server in Augment's
settings.json under mcpServers.gsd (Augment hosts MCP in settings.json, not a
standalone file). mergeGsdMcpServerIntoSettings mutates the in-memory settings
object finishInstall already writes (gated on hostBehaviors.mcpCompanion===
'settings-json'); non-destructive + idempotent; symmetric uninstall removal.
settings.json is golden-excluded, so no golden change. UPGRADE 1 (named/
background dispatch) + UPGRADE 2 (settings-json hook bus, Claude dialect)
were already live in production — this adds tests exercising both.
Golden: byte-identical for all 16 runtimes (folds preserve regex behavior;
MCP lives in golden-excluded settings.json) — verified by a real double-install
tree diff. Tests: declarative-reference-augment (adapter/axes/fail-closed/
undocumented-sub-axes + source-grep guard scoped to conversion-logic branches)
+ augment-upgrades (dispatch negotiation, hook-bus live install, MCP add/
idempotent/preserve/uninstall). Matrix + connect-gsd-mcp-server + a stale
install-on-your-runtime hook-ownership claim corrected; changeset (Changed).

deriveProgressFromRoadmap read the `## Progress` table with two
4-column-only regexes, so every project past its v1.0 milestone — which
uses the 5-column milestone-grouped shape the same template ships
(| Phase | Milestone | Plans Complete | Status | Completed |) — parsed to
{completedPhases: null, totalPhases: null, totalPlans: null}. Because the
body is wrapped in a bare try/catch the failure was silent, and
phase.complete flipped the ROADMAP row to Complete but never advanced
STATE's progress percent / completed-phase count.
Parse the table by header instead: locate the `## Progress` section
(line-anchored h2, mirroring the writer's #2012 scoping so an earlier
Phase/Status/Completed-shaped table can't hijack it), read the header row
to find the Status, Completed, and plans columns by name, then index each
data row positionally. One code path now handles both the 4-column
greenfield and 5-column milestone-grouped shapes — the same understanding
the writer (cmdPhaseComplete, with its `cells.length === 5` branch)
already had. Preserves the 999.x backlog exclusion, M/N plan summing, and
the prior contract that a count of 0 is reported as null.
Regression tests fold into tests/state.test.cjs: the template's own
5-column Progress block parses non-null, both shapes derive identically,
999.x stays excluded in the 5-column shape, and decoy tables (an earlier
## Retrospective table and an ### Progress h3 subheading) do not hijack
the scope.

Fold all runtime==='kimi'/isKimi logic branches into descriptor-driven
hostBehaviors (localInstallDeferred, verificationStyle, agentManifestStyle,
reapplyCommand, doneBannerStyle) + add 'kimi' to _DESCRIPTOR_AGENTS_RUNTIMES.
Kimi's skills/kimi-agents dispatch was already descriptor-driven (converter-by-
name + kimi-agents kind). Zero isKimi/runtime==='kimi' branches remain.
UPGRADE 1 (native hook bus): new hooksSurface 'kimi-hooks-toml' + a marker-
delimited config.toml [[hooks]] emitter (buildKimiHooksTomlBlock/writeKimiHooksToml
in runtime-hooks-surface.cts; resolveKimiHooksTomlDir in runtime-homes.cts).
GSD's lifecycle hooks now wire into Kimi's native ~/.kimi/config.toml (Context7-
confirmed path) at SessionStart/PreToolUse/Stop/PreCompact/SubagentStart/
SubagentStop — kimi becomes a hooks/ consumer (the 3 && !isKimi exclusion guards
removed). config.toml holds absolute install paths so it's golden-excluded via
an exact relative-path (.kimi/config.toml), not a basename (which would blind
Codex's config.toml). New hooksSurface value added to the closed enum in
capability-validator + runtime-config-adapter-registry.
UPGRADE 2 (background dispatch): flip dispatch.backgroundDispatch true (Kimi's
Agent tool takes run_in_background; root agent already gets the Agent tool), so
negotiation no longer flattens dispatch. subagentToolkit stays 'undocumented'
per AC (coder/explore/plan have distinct tool policies).
MCP transport explicitly deferred (no installer-driven MCP for any runtime).
Golden: only kimi.json changes (hooks/ scripts now installed); all 15 others +
claude-local byte-identical (kilo/zcode keep their own exclusions). Tests:
kimi-imperative-reference (adapter/axes/fail-closed/hostBehaviors + source-grep
guard) + kimi-upgrades (config.toml [[hooks]] SessionStart + marker idempotency
+ backgroundDispatch negotiation). CONTEXT.md glossary + matrix + how-to updated;
changeset (Added).

Fold trae logic branches into descriptor-driven reads: skipSharedHooksInstall
gates (dropped && !isTrae), and the case 'trae' path-rewrite arm now computes
the self-alias from the descriptor-driven dirName (.trae). Dead isTrae bindings
removed from uninstall/writeManifest/finishInstall. trae's skills dispatch was
already descriptor-driven (converter-by-name). RUNTIME_CONTENT_DISPATCH.trae is
left as a runtime-keyed table registration (its regex/callback rewrites can't be
a byte-identical descriptor map — matches cursor/windsurf/cline). trae stays in
RUNTIME_FLAG_IDS: isTrae still gates the agents-converter selection (agents out
of scope; removal gated on the cross-runtime agents-dispatch migration).
Byte-identical golden parity for all 16 runtimes.
UPGRADE: SOLO stage/trigger metadata — emitted Trae SKILL.md now carries
stage: workflow (descriptor-gated via hostBehaviors.soloStageMetadata) so
Trae's SOLO Agent can auto-invoke GSD skills at the corresponding stage. Field
shape is best-effort/inferred (Trae publishes no formal schema). trae.json
golden regenerated.
Tests: trae-imperative-reference (adapter/axes/fail-closed shouldFlattenDispatch
+ no runtime==='trae' source-grep, isTrae exempted for agents) + trae-upgrades
(stage: workflow on installed SKILL.md, descriptor-gated). Matrix note +
changeset added.

Fold remaining isKilo logic branches into descriptor-driven reads:
finishPermissionWriter (uninstall cleanup), skipSharedHooksInstall (hooks
copy), and a skills converter-name registry (the artifactLayout.converter
field is now load-bearing, not decorative). frontmatterDialect stays the
documented dispatch key for frontmatter (no descriptor field for it). Dead
isKilo destructure bindings removed. Byte-identical golden parity for all 16
runtimes (opencode, which shares kilo's combined-family path, verified clean).
UPGRADE 1 (hook bus): install .kilo/plugins/gsd-core.js native plugin +
extensionEvents:"kilo" + EXTENSION_EVENT_SURFACES.kilo (OpenCode-fork bus).
UPGRADE 2 (active model): populate runtimeTierDefaults.kilo + thread
modelOverride through convertClaudeToKiloFrontmatter — model no longer stripped
from agents. UPGRADE 3 (MCP): document the gsd-core MCP companion under kilo's
mcp config key. UPGRADE 4 (named dispatch): agents/*.md mode:subagent roster is
the Task-tool dispatch surface (tested); subagentToolkit stays 'undocumented'
per AC so dispatch degrades to 'degraded' by design.
Model-catalog single-source edit ripples the shared model-catalog.json hash
into all 16 golden fixtures (expected). Inline defect fixes (no-defer): stale-
bake-guard resolveAgentDir 'agent'->'agents' (was a silent no-op for opencode/
codex), hardcoded 'Removed OpenCode plugin' uninstall log -> generic, and the
connect-gsd-mcp-server.md OpenCode mcpServers->mcp doc error.
Tests: kilo-imperative-reference (adapter/axes/fail-closed/degradation/
hostBehaviors + widened isKilo source-grep across 4 modules) + kilo-upgrades
(plugin parity+load, model-override converter, agents dispatch surface, MCP
doc). Matrix + how-to + config docs updated; changeset added.

trek-e's re-review asked to either mechanize the Step 9.5 element
extraction or add an inline note justifying why it stays manual, so a
future maintainer doesn't read it as an oversight.
Verified the premise: the requirement-side edge-probe path (spec-phase
Step 5.5) it mirrors is ALSO a hand-populated heredoc + fail-loud
<replace:> placeholder guard — not a mechanical parse. The UI probe
mirrors that idiom verbatim. Mechanizing would be worse: a UI-SPEC has no
single machine-parseable "elements" column (surfaces are spread across the
design-token tables, Copywriting, and researcher-named prose), so a
regex/table parse would fail-OPEN (miss a prose-named surface, or feed a
design-token row as a bogus element).
Expanded the inline comment to state the parity + the fail-open rationale
explicitly. No logic change; regenerated the workflow size baseline and
the 16 golden-install-parity fixtures for the +847 B comment.
Refs #1867
Claude-Session: https://claude.ai/code/session_017vYn26e3nkDNxcpty1ciPJ
ci-preflight (full test:unit) caught a Phase-1 registration gap: the
tsc-generated gsd-core/bin/lib/ui-consideration-probe.cjs was not in the
eslint.config.mjs global ignore list, failing 551-eslint-bin-lib-coverage
("each bin/lib/*.cjs is linted xor ignored according to migration state",
ADR-457/#537). Generated artifacts are ignored, not linted — added it next to
the sibling probe adapters (edge-probe/probe-core/prohibition-enforcement).
Claude-Session: https://claude.ai/code/session_01BKt4hgNZwXSeJYJtYAQUSS
Ship-safe registration + regenerated snapshots for the #1867 UI-consideration
probe (Phase 3, SHIP-01):
- CONTEXT.md: PROBE.ui.{verification,axis,seam} predicates + ui-consideration
-probe added to PROBE.family (machine-canon for the 3rd adapter, MIXED axis).
- agents/gsd-ui-{researcher,checker}.md: one @-include of
references/ui-consideration-probe.md each (both under the 24576 agent cap).
- docs/INVENTORY.md + INVENTORY-MANIFEST.json: register the reference doc and
the compiled ui-consideration-probe.cjs (inventory-manifest-sync green).
- tests/fixtures/golden-install-parity/*.json (16 runtimes): recaptured against
a clean full build — folds in the deferred Phase-1 (ref doc, plan-phase lift)
and Phase-2 (ui-phase step, UI-SPEC section) install-surface changes.
- tests/agent-size-baseline.json: ratcheted the two grown UI agents.
- .changeset/vivid-orcas-chatter.md: type Added (pr updated at PR-open).
Inventory/golden/size gates green; lint:ci + lint:docs + lint:changeset green.
The plan-phase.md PRE_PHASE6 ceiling stays RED pending #1852 (unchanged).
Claude-Session: https://claude.ai/code/session_01BKt4hgNZwXSeJYJtYAQUSS
Record resolved UI-state considerations in the UI-SPEC, backward-compatibly
(Phase 2, WIRE-02). templates/UI-SPEC.md gains a '## UI Considerations' section
(analog of SPEC '## Edge Coverage') after '## Copywriting Contract' — a
| Category | Element(s) | Status | Resolution / Reason | table with
covered/backstop/unresolved rows in the locked probe-core projectTruths format
the shipped plan-phase lift (plan-phase.md:921) reads. Empty/error COPY stays in
Copywriting; this section covers shape-rooted STATE and references those rows
(de-dup).
Tests: docs-fixtures parsed-heading assertion (UI Considerations present +
distinct from Copywriting Contract; allow-test-rule, parsed structure); typed
backward-compat (projectTruths(undefined/[])===[], old UI-SPEC still plans —
Hyrum), format-match, and idempotency (proposeElements determinism). The
template-structure test was the RED driver.
Install-parity cascade (INVENTORY-MANIFEST + 16 golden fixtures +
agent-size-baseline) deferred to Phase 3 SHIP-01, as planned.
Claude-Session: https://claude.ai/code/session_01BKt4hgNZwXSeJYJtYAQUSS
Add the live ui-phase producer path for the UI-consideration probe (Phase 2,
WIRE-01). Two small exports on the Phase-1 adapter — proposeElements (the
propose-then-confirm view of detected kinds + applicable categories) and
autoResolve (the deterministic --auto floor that never dismisses and never
auto-backstops an unclassified item, #1110) — plus a post-verification
'## 9.5 UI-Consideration Probe' step in ui-phase.md mirroring spec-phase 5.5's
RUNTIME_DIR shim + fatal-invoke/malformed-report/zero-applicable fail-closed
guards, propose-then-confirm (the partial-cue recall mitigation), and the
'## UI Considerations' write-back in the shipped plan-phase.md:921 lift format.
autoResolve is the CODE floor; the covered-upgrade stays workflow prose (the
two-layer --auto). Un-upgraded backstops route to insufficient_spec ->
human_needed at verify, never a silent pass (#1154).
Tests: +8 typed (proposeElements shape/determinism, autoResolve never-dismiss,
partial-cue strict-subset) — structured-value only. ui-phase.md size baseline
ratcheted 15477->24447 (under DEFAULT cap). The plan-phase.md PRE_PHASE6 ceiling
stays RED pending #1852 (unchanged from Phase 1).
Claude-Session: https://claude.ai/code/session_01BKt4hgNZwXSeJYJtYAQUSS
Separate *-UI-SPEC.md glob (edge-coverage glob exclusion at :746 left intact
- Hyrum/D-08); a terse lift bullet reusing the ## Edge Coverage rule verbatim
(covered -> truths string, backstop -> flat scalar {statement, verification:
backstop}, unresolved -> assumption; no new verb - ADR-550 #1278/#1154); and a
no-silent-drop checklist line. Lift logic lives ONLY in the plan-phase
workflow, never gsd-planner.md (D-10, agent-size cap).
NOTE: this grows plan-phase.md +862B, over the #1168 PRE_PHASE6 ceiling (94519)
by ~802B, so the workflow-size gates are RED until #1852's lazy-split lands the
-21KB headroom. Deliberately does NOT raise the ceiling constant (would collide
with #1820/#1835's in-flight raise). #1867 sequences after #1852; rebase +
regenerate the size baseline then.
Reference doc mirrors edge-probe.md structure but links rather than re-argues;
states the MIXED-axis boundary (closed compiled shape-rooted subset here; open
UX subset - real-time/offline, a11y depth, i18n/RTL - prose-owned in
domain-probes.md). Docs-parity test pins doc taxonomy ids == code UI_TAXONOMY
ids and asserts disjointness from domain-probes.md topics (ADR-456
runtime-contract exemption, see #1867).
Third probe-core adapter on the UI element/state axis, mirroring edge-probe.
Closed 8-id shape-rooted UI_TAXONOMY + element-cue relevance filter
(UI_CUES -> classifyElement -> applicableCategories); unclassified fail-loud
soft-signal (#1110); fail-closed on invalid authored element kinds. All
lifecycle/merge/validation delegated to probe-core verbatim (no fork). Item
question carried in the shared Item.probe field. LIFT-01 proven at the
probe-core primitive level (projectTruths/dispositionForUnverifiableTruth):
backstop considerations route to insufficient_spec, never a silent pass.
Tests assert typed returns off the built .cjs (no source-grep).
#2056 fixed the foreign-prefix collapse for init plan-phase only.
The identical defect remained in three sibling commands that called
findPhaseInternal/getRoadmapPhaseInternal without the guard:
- cmdInitExecutePhase
- cmdInitVerifyWork
- cmdInitPhaseOp
Extracted the #2056 guard into shared helpers (guardedFindPhase /
guardedGetRoadmapPhase) and routed all four init commands through them.
Deleted the local parsePhasePrefix/isForeignPrefixedPhaseQuery copies in
init.cts — the canonical export from phase-id.cts is now used directly,
eliminating the drift risk flagged by both reviewers.
Added 5 regression tests (3 reject + 2 accept-branch) mirroring the
#2056 plan-phase tests.
Update runtimeTierDefaults.codex and providerPresets.openai in
model-catalog.json to the GPT-5.6 family (gpt-5.6-sol/terra/luna),
advancing from the superseded GPT-5.4/5.5 generation.
Model IDs verified against OpenAI developer API docs:
- gpt-5.6-sol: flagship, /, reasoning xhigh
- gpt-5.6-terra: balanced, .50/, reasoning medium
- gpt-5.6-luna: fast/cheap, /, reasoning medium
Tier mapping is 1:1 (Sol↔flagship, Terra↔balanced, Luna↔fast),
so profile semantics are unchanged — only the underlying IDs advance.
Updates: catalog JSON, test assertions (catalog defaults), docs
(CONFIGURATION.md + zh-CN/pt-BR translations, workflow settings),
and changeset.
Closes#2122
Final convergence review found the shared <tag> seam introduced 3 behavior
regressions; fixed all + locked with tests:
- #557 REGRESSION: stripTaggedBlocks's attribute-tolerance stripped `<details open>`
(the ACTIVE-milestone marker) that the old `<details>`-only regex preserved. The
seam now takes `allowAttributes` (default false) — details/decisions strip is
attr-INTOLERANT (preserves `<details open>`); only `<task type="…">` opts in.
Regression test added to roadmap-parser + markdown-sectionizer suites.
- verify.cts actionZones (negative-grep-echo security scan): reverted to a bounded
to-first-close scan `<action>([\s\S]{0,20000}?)</action>` so a grep-echo trick
can't hide behind an unterminated inner <action> (the seam's stop-at-next-open
would drop it). ReDoS-safe via the cap.
- check-command-router HTML-comment strip: `(?:-->|$)` fallback wiped to EOF
(fail-closed spurious gate block) — replaced with stop-at-next-open so an
unclosed `<!--` leaves downstream tags intact.
- Updated the extractTaggedBlocks nested-tag tests to the new (stop-at-next-open)
behavior: `<x><x>inner</x></x>` -> ['inner'].
All vectors still linear; every fix verified in-process.

A convergence audit showed the `<tag>[\s\S]*?</tag>` lazy-scan ReDoS was pervasive
(a dozen+ bespoke copies across roadmap-parser/check-command-router/verify), each
a distinct quadratic vector on a large document with unclosed tags. Rather than
whack-a-mole, single-source them (maintainer-directed):
- markdown-sectionizer: extractTaggedBlocks now shares one ReDoS-safe
`taggedBlockPattern` (stop-at-next-open, bounded optional attributes) and gains
a `stripTaggedBlocks` companion for block removal.
- roadmap-parser: 3 `<details>` strips -> stripTaggedBlocks (behavior-identical —
no <details> here carries attributes).
- verify: actionZones + both <task> loops + their nested <name>/<files>/gate/req
extractions -> extractTaggedBlocks (behavior byte-equivalent, verified).
- check-command-router: the objective|tasks?|action alternation hardened in place
(distinct multi-tag shape); HTML-comment strip gains a `$` fallback.
Every vector now linear (<3ms on 1.5MB adversarial); real content unchanged
(end-to-end verify/roadmap resolution + task extraction confirmed). The only
remaining `<!--…-->` scan (uat.cts:201) is anchored + non-global — one scan, safe.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
A ReDoS-completeness audit surfaced a distinct class beyond the tag/bracket
clause: unbounded `[\s\S]*?` / `[^\]]*` lazy-scans searching for a literal
terminator that may never appear, driven quadratic by REPEATED structures in a
large PLAN.md/ROADMAP.md. Folded all 7 in at maintainer direction:
- files_modified `[^\]]*` -> `[^\]]{0,8000}` (commands.cts, verify.cts): 39.7s -> 0.9s.
- Plans-count `[\s\S]*?` -> section-local `(?:(?!\n#{1,4}\s)[\s\S])*?` — stops at the
next heading (semantically correct: Plans: belongs to the phase's own section)
(roadmap.cts x3, phase.cts): 36s -> 4ms.
- <tag> extraction `([\s\S]*?)` -> stop at the next same-tag opening
`((?:(?!<tag>)[\s\S])*?)` (verify.cts x3, markdown-sectionizer.cts): ~6s -> 2ms.
Every vector is now linear (comprehensively re-measured); real content matches
(end-to-end `roadmap get-phase` still resolves Plans-counted phases). Pre-existing;
byte-behavior preserved for realistic inputs.

Review caught that the prior commit bounded only the paren tag clause and left
the SIBLING bracket-prefix `(?:\[[^\]]+\]\s*)?` (same host regexes, before Phase)
UNBOUNDED — the identical quadratic reachable via a `[...]` run (measured ~16s at
1.7MB). Bound `[^\]]+`/`[^\]]*` -> {1,200}/{0,200} across all 19 phase/milestone
heading prefixes. Comprehensive re-measurement now shows EVERY vector linear
(bracket/paren/id/name/milestone all ~2-44ms at 2.45MB; bracket scaling
2k->2ms, 4k->5ms, 8k->10ms). Also: update the #1729 literal-mirror parity test
off its stale unbounded constant, and add limit-1 (199) boundary coverage.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The canonical OPTIONAL_PHASE_TAG_SOURCE tag clause `(?:\s*\([^)\n]*\))?` (and its
inlined literal mirrors across 11 modules) had an UNBOUNDED body, making the
optional-group + /g header scan quadratic on adversarial ROADMAP.md/STATE.md — a
long run of `(` after a header ran ~18.8s at 1.7MB. Bound the body to {0,200} in
the constant AND every mirror in lockstep (the #1729 "both forms change together"
contract), so the scan is linear: the same 1.7MB input now resolves in ~9ms
(measured), while real tags (a handful of chars) still match and a 201-char tag
is rejected. Added a #2128 boundary regression to the #1729 suite.
Pre-existing (byte-identical before/after the Phase 4 migrations); folded in at
maintainer direction rather than deferred.
