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.

GSD smart entry — the state-aware front door. Detect the current project situation via `gsd_run smart-entry --json`, present a short menu of the right next actions, and dispatch to exactly one existing GSD command. This is a launcher/router only; it never does the work itself.

This is a menu front door, not a second router. For in-project forward motion (planning → executing → verify-pending) the recommended action is /gsd:progress --next, which delegates to the single gated advancement engine (workflows/next.md: Route 0 resume-incomplete-phase + Gates 1-3). smart-entry adds value only where --next cannot reach: pre-project, remediation (paused/blocked/verify-failed), and lifecycle exits (idle-stranded/complete). See docs/adr/1787-gsd-next-smart-entry.md.

**TEXT_MODE handling (non-Claude runtimes).**

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.

**Resolve the gsd_run shim.**

Run this resolver block exactly. It locates gsd-tools.cjs across every supported runtime home and defines a gsd_run function. If it cannot find the tool, it prints the standard install hint and exits non-zero.

**Detect the situation.**

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

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.

Parse SNAPSHOT as JSON. It has the shape:

{
  "situation": "executing",
  "recommended": "progress-next",
  "summary": "Phase 2 of 5 · 60% · executing",
  "signals": { "...": "..." },
  "actions": [
    { "id": "progress-next", "label": "Advance to the next step", "command": "/gsd:progress --next", "recommended": true },
    { "id": "execute-phase", "label": "Continue executing phase 2", "command": "/gsd:execute-phase", "recommended": false }
  ]
}

situation is one of: no-project, paused, blocked, verify-failed, needs-first-phase, planning, executing, verify-pending, idle-stranded, complete, unknown.

Fallback (never strand the user): smart-entry --json can fail for two reasons, and each has a different recovery. Parse SNAPSHOT; if it is empty, not valid JSON, or missing actions, apply the first matching recovery below — do NOT error.

  1. gsd-tools itself is broken (the failure is a Cannot find module ... / Node crash, not just an empty result). Probe by running gsd_run state-snapshot — if THAT also errors, the whole tool layer is down and routing to /gsd:progress would dead-end too (it also needs gsd-tools). Recover by reading state directly:

    • Read .planning/STATE.md (frontmatter + body) with the Read tool. Extract: status (frontmatter status: or body **Status:**), Phase: from the body, total_phases/percent from a nested progress: frontmatter object if present, and any ## Blockers items.
    • Synthesize a minimal result: situation = your best guess from the status text (executing/verifying/planning/complete/paused), summary = a one-line read ("Phase N of M · status"), and an actions list built from status (e.g. verifying → /gsd:verify-work, executing → /gsd:execute-phase, else /gsd:progress), always including /gsd:quick and /gsd:help.
    • Print one line first: smart-entry unavailable (gsd-tools error) — reading state directly. The gsd-tools layer may need a rebuild (rm tsconfig.build.tsbuildinfo && npm run build).
    • Proceed to the present step with this synthesized result.
  2. Only smart-entry is unavailable (e.g. older gsd-core without the subcommand; state-snapshot still works). Run /gsd:progress and stop. Print one line first: smart-entry unavailable — showing progress.

**Present the menu.**

Show the summary line to orient the user, then offer the actions.

If TEXT_MODE is false: call AskUserQuestion with:

  • header: a short label derived from situation (e.g. executing → "Continue work", blocked → "Unblock", no-project → "Get started", complete → "What next?").
  • question: the summary line, then "What would you like to do?"
  • options: the first 4 entries of actions[] in order. For each, label = the action's label, description = the action's command. The recommended action is already first; surface it as the first option. The user may also type a custom command (handled automatically).

If TEXT_MODE is true: print the summary, then a numbered list of ALL actions[] (not capped to 4 — text has no limit), then ask the user to type the number of their choice:

{summary}

  1. {actions[0].label}  ({actions[0].command})
  2. {actions[1].label}  ({actions[1].command})
  ...

Type a number, or describe what you want to do.

Wait for the user's response before continuing. Map the chosen number to the corresponding action.

**Show the routing decision.**
### GSD ► SMART ENTRY

**Situation:** {situation}
**Routing to:** {chosen command}
**Dispatch and stop.**

Invoke the chosen action's command. If the user typed a free-form response instead of picking an action, treat it as freeform intent and route via /gsd:progress --do "<their text>".

After invoking the command, stop. The dispatched command owns everything from here. Do not continue, do not chain, do not re-enter this workflow.

<success_criteria>

  • Situation detected via gsd_run smart-entry --json
  • Summary shown to orient the user
  • Menu offered (AskUserQuestion, or numbered list under TEXT_MODE)
  • Routing decision displayed before dispatch
  • Exactly one command dispatched
  • Any detection failure falls back to /gsd:progress (never strands the user)
  • No work done directly — launcher only </success_criteria>
