Tom Boucher fb2d122d7f feat(#3841): assert gsd-tools identity on every state-mutating verb (#3848)
* feat(#3841): assert gsd-tools identity before any state-mutating verb

only this package publishes. The path-based branches — a project-local install,
a runtime config directory — had no such guarantee; they trusted their
configured location. This closes them.

Mechanism: once resolution finishes, and before any verb runs, the preamble
probes the tool it picked with `runtime-identity --raw` and matches the answer
with a shell `case` pattern ANCHORED to the start of the compact payload
(`{"packageName":"@opengsd/gsd-core"`). An unanchored substring match accepts
the decoy `{"packageName":"get-shit-done-cc","note":"@opengsd/gsd-core"}`, which
any colliding package could publish. The outcome is exported as the two-valued
`GSD_IDENTITY_STATUS` (`ok`/`unverified`), so the gate is asserted on a VALUE
rather than on warning prose. Rollout is warn-then-fail per the #3146 ruling:
`unverified` prints one line naming BOTH causes and continues, because
`no_identity_verb` cannot tell a foreign package from an `@opengsd/gsd-core`
older than the verb, and at rollout the old-version case is the common one.

The blocker was byte budget, not design. The preamble is inlined into 112
shipped files and several sat within single-digit bytes of frozen ceilings
(`gsd-verifier.md` 16 bytes, `gsd-executor.md` 33, `execute-phase.md` 234); a
first attempt broke five of them. What made room was collapsing the resolver's
twenty near-identical `elif [ -f … ]` arms into one candidate-list helper
(`_gsd_at`), which buys far more than the assertion costs. The preamble is now
2,624 bytes against 4,500 — a net 1,876 bytes SMALLER per inlined file, so every
capped file moved away from its ceiling rather than toward it. No cap raised, no
size-budget exception added, no override token emitted.

Resolution order, every runtime-home probe, the `unset -f gsd_run` re-source
fix, the fail-closed `exit 1`, and the `CLAUDE_ENV_FILE` persistence are all
preserved byte-for-byte in substring terms; the snippet still begins with
`_GSD_SHIM_NAME=` and still ends with `fi`, which the parity extractors anchor
on. `gsd-core/references/gsd-run-resolver.md` is re-synced byte-equal.

Also fixes two stale claims found in passing: CONTEXT.md and FEATURES.md both
described an `[ -x ]` guard as the load-bearing re-source defense. That guard
was tried and REMOVED in #3831 — it rejected the bare function name, fell
through every branch, and hit `exit 1`, which kills a sourced caller's shell.
`unset -f gsd_run` is the actual mechanism.

* fix(#3841): pair the anchor's brace by requiring a closed identity payload

The matrix went red on `tests/new-project-mvp-prompt.test.cjs` — "new-project.md
has unbalanced braces: net depth 2" — plus a knock-on report from its parent
`bug #1516` describe, which is the same failure counted once at the child and
once at the block.

Root cause: that guard (:182-189, mirroring #3784 bd53925f) walks characters and
increments on `{`, decrements on `}`, with no awareness of shell quoting. It
scans `new-project.md` PLUS every `new-project/steps/*.md`, and both
`new-project.md` and `steps/auto-mode-config.md` carry one inlined preamble copy
— hence net 2 from a snippet that was off by exactly one. The unpaired brace was
the `{` inside the single-quoted `case` pattern of the identity anchor, which is
correct shell and invisible to a text scanner.

Fix in the snippet, not the guard. The pattern now anchors at BOTH ends:
`'{"packageName":"@opengsd/gsd-core"'*'}'`. That balances 51/51 with a brace that
does real work rather than a cosmetic pair — a truncated payload whose prefix
matches now fails too, where before it verified. Safe for any future additive
field: a JSON object's own closing brace is always the last character, whatever
type the last value has, which is pinned by two negative-space tests (a nested
object and an array-valued last key must both still verify). Cost: +3 bytes,
against the 1,873 the resolver fold already gave back.

The alternative considered and rejected was dropping the literal `{` for a `?`
glob. It balances too, but weakens the anchor from "must be an opening brace" to
"must be any one character", and the anchor is the entire point.

Two guards added so this cannot recur silently:
- runtime-launcher-parity (F0) pins brace balance at the SNIPPET, so the next
  edit to that pattern fails on the file it broke instead of surfacing three
  files downstream in a test whose name mentions neither the launcher nor this
  issue. It also asserts depth never goes negative, since a `}` preceding its
  `{` nets to zero while being unbalanced at every prefix.
- runtime-identity gains behavioral truncated-payload and trailing-garbage
  fixtures, so the added `}` is proven load-bearing rather than merely present.

Verified: snippet 51/51 braces; new-project combined net depth 0; the seven
other preamble-bearing files with nonzero depth are unchanged from merged next
(their own prose, not the preamble, and not in any guard's scan set); all 112
inlined copies and the resolver reference re-synced byte-equal; sync:launcher
idempotent on the second run.

Analyze freeform text from the user and route to the most appropriate GSD command. This is a dispatcher — it never does the work itself. Match user intent to the best command, confirm the routing, and hand off.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

RESPONSE_LANGUAGE=$(gsd_run query config-get response_language --default "" 2>/dev/null || echo "")

If response_language is set: All user-facing questions, prompts, and explanations in this workflow MUST be presented in {response_language}. Technical terms, code, file paths, and subagent prompts stay in English — only user-facing output is translated.

**Check for input.**

Text mode (workflow.text_mode: true in config or --text flag): Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where AskUserQuestion is not available. If $ARGUMENTS is empty, ask via AskUserQuestion:

What would you like to do? Describe the task, bug, or idea and I'll route it to the right GSD command.

Wait for response before continuing.

**Check if project exists.**
INIT=$(gsd_run query state.load 2>/dev/null)

Track whether .planning/ exists — some routes require it, others don't.

**Match intent to command.**

Evaluate $ARGUMENTS against these routing rules. Apply the first matching rule:

If the text describes... Route to Why
Starting a new greenfield project, "set up", "initialize" /gsd:new-project Needs full project initialization
First-time setup for an existing codebase, brownfield onboarding /gsd:onboard Safe map → docs ingest → project setup sequence
Mapping or analyzing an existing codebase map /gsd:map-codebase Codebase discovery or refresh
A bug, error, crash, failure, or something broken /gsd:debug Needs systematic investigation
Spiking, "test if", "will this work", "experiment", "prove this out", validate feasibility /gsd:spike Throwaway experiment to validate feasibility
Sketching, "mockup", "what would this look like", "prototype the UI", "design this", explore visual direction /gsd:sketch Throwaway HTML mockups to explore design
Wrapping up spikes, "package the spikes", "consolidate spike findings" /gsd:spike --wrap-up Package spike findings into reusable skill
Wrapping up sketches, "package the designs", "consolidate sketch findings" /gsd:sketch --wrap-up Package sketch findings into reusable skill
Exploring, researching, comparing, or "how does X work" /gsd:explore Socratic ideation and idea routing
Discussing vision, "how should X look", brainstorming /gsd:discuss-phase Needs context gathering
A complex task: refactoring, migration, multi-file architecture, system redesign /gsd:phase Needs a full phase with plan/build cycle
Planning a specific phase or "plan phase N" /gsd:plan-phase Direct planning request
Executing a phase or "build phase N", "run phase N" /gsd:execute-phase Direct execution request
Running all remaining phases automatically /gsd:autonomous Full autonomous execution
A review or quality concern about existing work /gsd:verify-work Needs verification
Checking progress, status, "where am I" /gsd:progress Status check
Resuming work, "pick up where I left off" /gsd:resume-work Session restoration
A note, idea, or "remember to..." /gsd:capture Capture for later
Adding tests, "write tests", "test coverage" /gsd:add-tests Test generation
Completing a milestone, shipping, releasing /gsd:complete-milestone Milestone lifecycle
A specific, actionable, small task (add feature, fix typo, update config) /gsd:quick Self-contained, single executor

Requires .planning/ directory: All routes except /gsd:new-project, /gsd:onboard, /gsd:map-codebase, /gsd:spike, /gsd:sketch, and /gsd:help. If the project doesn't exist and the route requires it, suggest /gsd:onboard for existing codebases or /gsd:new-project for greenfield projects.

Ambiguity handling: If the text could reasonably match multiple routes, ask the user via AskUserQuestion with the top 2-3 options. For example:

"Refactor the authentication system" could be:
1. /gsd:phase — Full planning cycle (recommended for multi-file refactors)
2. /gsd:quick — Quick execution (if scope is small and clear)

Which approach fits better?
**Show the routing decision.**
### GSD ► ROUTING

**Input:** {first 80 chars of $ARGUMENTS}
**Routing to:** {chosen command}
**Reason:** {one-line explanation}
**Invoke the chosen command.**

Run the selected /gsd-* command, passing $ARGUMENTS as args.

If the chosen command expects a phase number and one wasn't provided in the text, extract it from context or ask via AskUserQuestion.

After invoking the command, stop. The dispatched command handles everything from here.
