enhance(#4139): Phase 2 — one shared gate, one pilot split, one accuracy spot-check (#4471)

* enhance(#4402): split plan-phase into a spine + detail, add the shared compact-content gate

ADR-4139 Decisions 3-5, Phase 2 of the #4139 Compact Content epic. Pilot
split for plan-phase.md, the largest of the 58 eagerly-@-included workflow
files (98,290 bytes): the spine keeps every happy-path step, every
protected-content block (planner/checker prompt templates, quality gates,
the failing-direction few-shot example, the two ScheduleWakeup guardrail
paragraphs — each marked with a <!-- gsd:protected --> sentinel), and
condensed one-paragraph summaries of five rare/opt-in fallback paths
(planner and checker filesystem-hang recovery, phase-split recommendation,
source-audit gaps, the thinking-partner conditional, and plan bounce). The
full text of those five moves verbatim to gsd-core/workflows/plan-phase/detail.md
(9.9KB, well under the 32,768-byte NEW_FILE_CAP), read by the spine only
when workflow.compact_content is false (the default) — the exact same
resolution rule now stated once in the new shared
gsd-core/references/compact-content-gate.md, which every future split
references instead of restating.

Verified mechanically (tests/plan-phase-compact-split.test.cjs, scoped to
this one split — Phase 3/#4403 owns the generalized guard): the union of
spine + detail contains every non-trivial line the parent commit carried
(0 missing), no non-trivial line is duplicated between them (0 duplicated),
and every declared protected block is well-formed and non-empty. The spine
shrinks from 98,290 to 93,206 bytes (-5.2% of the eager-window cost this
epic exists to reduce); detail.md's 9,853 bytes are only ever paid by a
project that has NOT opted in.

Verified live, end to end, twice, against this actual repo (not a
synthetic fixture) — real gsd-planner and gsd-plan-checker subagent
spawns, real PLAN.md output:
- workflow.compact_content=false: planned a real disposable phase
  (a docs/how-to page for enabling the key itself); planner returned
  PLANNING COMPLETE, checker returned VERIFICATION PASSED, all fact-checks
  against real repo state confirmed.
- workflow.compact_content=true (detail.md never read): planned a second
  real disposable phase; planner returned PLANNING COMPLETE with
  frontmatter.validate and verify.plan-structure both clean, again fully
  grounded against real repo state. The five condensed fallback sections
  were independently re-read spine-only and confirmed sufficient to act on
  correctly without detail.md's elaboration.

Also drafts gsd-core/references/compact-content-protected-content.md — the
protected-content category list and <!-- gsd:protected --> sentinel syntax
ADR-4139 Decision 5 calls for, written to move to Phase 3 (#4403) unchanged
once it lands there.

* fix(#4402): move detail.md into the ADR-4139-mandated detail/ subdirectory

Two independent review sub-agents (Standards and Spec axes of /code-review)
caught the same structural defect: ADR-4139 Decision 6 mandates
gsd-core/workflows/<name>/detail/*.md ("one or more parts... individually
skippable"), and this PR had shipped a flat plan-phase/detail.md instead,
copying issue #4402's own (inconsistent) restatement rather than the
locked ADR text. Fixed by git-mv to plan-phase/detail/elaboration.md and
updating every cross-reference (the spine's step 0.5 gate pointer, the
shared compact-content-gate.md's own resolution-rule wording, and the
completeness test's path constants).

Also, from the same review pass:
- docs/CONFIGURATION.md and gsd-core/references/planning-config.md's
  workflow.compact_content rows said "nothing branches on it yet" — no
  longer true now that plan-phase.md's spine does. Updated both to name
  plan-phase as the pilot and note the rest of the corpus is still pending.
- Regenerated all 19 tests/fixtures/install-tree/*.json golden fixtures
  (npm run gen:install-tree) — the three new shipped files were missing
  from the installer emitted-tree goldens.
- Found via a cache-busted `eslint . --max-warnings 0` (this repo's
  eslint --cache has produced false-greens before): the split test's
  `git show` call had a bare `timeout: 10000` literal, tripping
  local/no-adhoc-timeout-literal. Extracted to the existing GIT_TIMEOUT_MS
  constant from tests/helpers/timeouts.cjs instead of a second guessed
  copy of the same class of timeout.

Verified NOT needed, by tracing the actual mechanism rather than asserting
(tests/helpers/emitted-provenance.cjs's gsd-core-verbatim rule attributes
every gsd-core/{workflows,references}/** path to itself as an identity
source): an Emitted-Drift-Ack-Hash/-Growth trailer. Every changed/added
path in this diff is hand-authored and present in the diff itself, so
diffEmitted's attribution loop resolves `via` to the path's own source
before ever reaching the ack-lookup branch — there is no unattributed
delta to acknowledge. The spine also shrank (98,290 to 93,206 bytes), so
the growth ratchet has nothing to ack either.

Re-verified after these changes: the completeness/disjointness self-check
(0 missing, 0 duplicated) still holds against the relocated detail file,
and a full `npm run lint:ci` passes clean with the eslint cache cleared.

* fix(#4402): restore literal content the pre-existing drift guards pin on

The first gsd-test run against this split (19 failures) surfaced real
regressions: several pre-existing structural guards pin the EXACT text
of the sections this split condensed, and paraphrasing broke them.

- tests/plan-phase-drift-guard.test.cjs expects the literal
  `DISK_PLANS=$(gsd_run query find-phase ...)` bash assignment inside
  plan-phase.md itself, not a prose description of the same check.
  Restored the exact line into both §9a and §11a's spine summaries.
- tests/thinking-partner.test.cjs expects plan-phase.md to literally
  offer "No, I'll decide" as the skip option. Restored that exact
  phrase into the condensed thinking-partner paragraph.
- Both restores would have duplicated the same text into
  plan-phase/detail/elaboration.md (which still carries the full
  elaboration). Removed the now-redundant restatements from the
  detail file instead of leaving them duplicated — the spine already
  computes DISK_PLANS before the detail elaboration is ever read, so
  the detail file references it rather than recomputing it.
- Re-running scripts/sync-runtime-launcher.cjs after that edit found
  the canonical gsd_run preamble had also become an unintentional
  spine/detail duplicate (both files call gsd_run and each is
  required, by runtime-launcher-parity's own contract, to carry its
  own copy). That's sanctioned duplication under a DIFFERENT
  contract, not lost/copy-pasted content, so
  tests/plan-phase-compact-split.test.cjs now excludes it from the
  disjointness check the same way it already excludes trivial
  fences/headings.
- Applied the adversarial-review finding on tests/plan-phase-compact-split.test.cjs's
  own isTrivial(): a blanket `line.length <= 15` cutoff silently
  swallowed real content (e.g. the 14-char `<quality_gate>`
  sentinel). Replaced it with a specific bare-label-line pattern
  (`Options:`, `Display banner:` etc.) — verified 0 missing / 0
  duplicated against the actual split, an improvement over both the
  original cutoff and a naive full removal (which produces
  false-positive "duplicates" on generic recurring labels).
- gsd-core/references/planning-config.md's own workflow.compact_content
  row used `/gsd-plan-phase` (hyphen). That file is Claude-facing
  source text (gsd-core/references/), which tests/slash-command-namespace.test.cjs
  requires in colon form; docs/CONFIGURATION.md's use of the hyphen
  form is correct as-is since docs/ is human-facing and outside that
  test's scanned directories. Fixed to `/gsd:plan-phase`.
- tests/plan-phase-compact-split.test.cjs's own `git show` of the
  parent commit failed inside the gsd-test sandbox ("detected dubious
  ownership") because the checkout is mounted under a UID the
  invoking user doesn't own. Scoped `-c safe.directory=<repo-root>`
  to that one git invocation rather than touching global git config.
- docs/INVENTORY.md still had one outstanding "detail.md part" wording
  fix from the earlier adversarial-review pass, staged now.

Re-verified locally against the exact assertions in all four affected
test files (all pass) before dispatching a fresh gsd-test run — no
change here should have broken any of the other 18 gates; `npm run
lint` is clean with the eslint cache cleared.

* fix(#4402): restore the full marker enumeration to §9a's spine trigger line

The isolated Spec-axis review flagged that §9a's "Triggered when" line was
condensed to "Agent() returns but the return contains no recognized
marker" — dropping the literal `## PLANNING COMPLETE` / `## PHASE SPLIT
RECOMMENDED` / `## ⚠ Source Audit` / `## CHECKPOINT REACHED` /
`## PLANNING INCONCLUSIVE` enumeration, which is exactly the "machine-
parsed structural headings" category compact-content-protected-content.md
lists as protected. The load-bearing use of that same list (the
gsd_stall_watch call and the Handle Planner Return bullets a few lines
above) was never touched — only this one descriptive restatement was
genericized — but leaving any instance of a protected category
unsentineled is the silent erosion ADR-4139 Decision 4(c) warns
sufficiency isn't machine-checkable enough to catch on its own. Restored
the full enumeration into the spine.

That reintroduced an exact duplicate into plan-phase/detail/elaboration.md,
which still stated the same trigger sentence verbatim. Reworded the
detail file's version to reference the spine's trigger condition instead
of restating it, since the spine is now the single place that sentence
lives in full — mirroring the DISK_PLANS/"already computed above" pattern
from the previous commit.

Re-verified locally: completeness/disjointness (0 missing, 0 duplicated)
and all previously-fixed literal-content assertions still hold.

## 9b. Handle Phase Split Recommendation
When the planner returns `## PHASE SPLIT RECOMMENDED`, it means the phase's source items exceed the context budget for full-fidelity implementation. The planner proposes groupings.
**Extract from planner return:**
- Proposed sub-phases (e.g., "17a: processing core (D-01 to D-19)", "17b: billing + config UX (D-20 to D-27)")
- Which source items (REQ-IDs, D-XX decisions, RESEARCH items) go in each sub-phase
- Why the split is necessary (context cost estimate, file count)
**Present to user:**
```
## Phase {X} exceeds context budget for full-fidelity implementation
The planner found {N} source items that exceed the context budget when
planned at full fidelity. Instead of reducing scope, we recommend splitting:
**Option 1: Split into sub-phases**
- Phase {X}a: {name} — {items} ({N} source items, ~{P}% context)
- Phase {X}b: {name} — {items} ({M} source items, ~{Q}% context)
**Option 2: Proceed anyway** (planner will attempt all, quality may degrade past 50% context)
**Option 3: Prioritize** — you choose which items to implement now,
rest become a follow-up phase
```
Use AskUserQuestion with these 3 options.
**If "Split":** Use `/gsd:phase --insert` to create the sub-phases, then replan each.
**If "Proceed":** Return to planner with instruction to attempt all items at full fidelity, accepting more plans/tasks.
**If "Prioritize":** Use AskUserQuestion (multiSelect) to let user pick which items are "now" vs "later". Create CONTEXT.md for each sub-phase with the selected items.
When the planner returns `## PHASE SPLIT RECOMMENDED`, the phase's source items exceed the context budget for full-fidelity implementation. Extract the planner's proposed sub-phase groupings and present the user three options via AskUserQuestion: Split into sub-phases (use `/gsd:phase --insert`, then replan each), Proceed anyway (return to planner accepting degraded quality), or Prioritize (AskUserQuestion multiSelect to choose now vs. later, create CONTEXT.md per sub-phase).

## 9c. Handle Source Audit Gaps
When the planner returns `## ⚠ Source Audit: Unplanned Items Found`, it means items from REQUIREMENTS.md, RESEARCH.md, ROADMAP goal, or CONTEXT.md decisions have no corresponding plan.
**Extract from planner return:**
- Each unplanned item with its source artifact and section
- The planner's suggested options (A: add plan, B: split phase, C: defer with confirmation)
**Present each gap to user.** For each unplanned item:
```
## ⚠ Unplanned: {item description}
Source: {RESEARCH.md / REQUIREMENTS.md / ROADMAP goal / CONTEXT.md}

Options:
1. Add a plan to cover this item (recommended)
2. Split phase — move to a sub-phase with related items
3. Defer — add to backlog (developer confirms this is intentional)
```
Use AskUserQuestion for each gap (or batch if multiple gaps).
**If "Add plan":** Return to planner (step 8) with instruction to add plans covering the missing items, preserving existing plans.
**If "Split":** Use `/gsd:phase --insert` for overflow items, then replan.
**If "Defer":** Record in CONTEXT.md `## Deferred Ideas` with developer's confirmation. Proceed to step 10.

For each `*-PLAN.md`: back it up to `*-PLAN.pre-bounce.md`, invoke `${BOUNCE_SCRIPT}` with the plan file and `workflow.plan_bounce_passes` (default 2), validate the result's YAML frontmatter integrity, and restore from backup on either broken frontmatter or a non-zero script exit. After all plans are bounced, re-run the plan checker (step 10) on the modified plans, restoring any that fail. Commit surviving bounced plans if at least one survived (`refactor(${padded_phase}): bounce plans through external refinement`), display a `{survived}/{total}` summary, and remove all `*-PLAN.pre-bounce.md` backups.

# plan-phase — Detail
Elaboration deferred from the `plan-phase.md` spine under ADR-4139 (Compact Content mode). Read via `gsd-core/references/compact-content-gate.md` when `workflow.compact_content` is `false`. This file supplements the spine — it does not stand alone.
## § 9a — Filesystem Fallback (Planner)
This elaborates the spine's §9a trigger condition (above) — the recovery banner and its three options.
```bash
# #3218: this asks "did the planner write files to disk at all" — a
# planner-produced-nothing check, not outstanding-work counting — so it
# takes the PHYSICAL set (`plan_count_all`, status:superseded INCLUDED): a
# superseded plan is still a file the planner wrote, and this check must not
# read "nothing written" just because every plan happens to be superseded.
```
The spine already computed `DISK_PLANS` (above) before reaching this elaboration.
**If `DISK_PLANS` > 0:** The planner wrote plans to disk but the Agent() return was empty or
truncated (the Windows stdio hang pattern — the subagent finished but the return never
arrived). Display:
```text
◆ Planner wrote {DISK_PLANS} plan(s) to disk but did not emit a PLANNING COMPLETE marker.
This is a known Windows stdio hang pattern — work is likely recoverable.
Plans found on disk:
{ls output of *-PLAN.md}
```
Offer 3 options:
1. **Accept plans** — treat as `## PLANNING COMPLETE` and continue through step 9 `## PLANNING COMPLETE` handling (so `--skip-verify` / `plan_checker_enabled=false` are honored — may skip to step 13 rather than step 10)
2. **Retry planner** — re-spawn the planner with the same prompt (return to step 8)
3. **Stop** — exit; user can re-run `/gsd:plan-phase {N}` to resume
**If `DISK_PLANS` is 0 and no marker:** The planner produced no output. Treat as
`## PLANNING INCONCLUSIVE` and handle accordingly.
## § 9b — Handle Phase Split Recommendation
When the planner returns `## PHASE SPLIT RECOMMENDED`, it means the phase's source items exceed the context budget for full-fidelity implementation. The planner proposes groupings.
**Extract from planner return:**
- Proposed sub-phases (e.g., "17a: processing core (D-01 to D-19)", "17b: billing + config UX (D-20 to D-27)")
- Which source items (REQ-IDs, D-XX decisions, RESEARCH items) go in each sub-phase
- Why the split is necessary (context cost estimate, file count)
**Present to user:**
```
## Phase {X} exceeds context budget for full-fidelity implementation
The planner found {N} source items that exceed the context budget when
planned at full fidelity. Instead of reducing scope, we recommend splitting:
**Option 1: Split into sub-phases**
- Phase {X}a: {name} — {items} ({N} source items, ~{P}% context)
- Phase {X}b: {name} — {items} ({M} source items, ~{Q}% context)
**Option 2: Proceed anyway** (planner will attempt all, quality may degrade past 50% context)
**Option 3: Prioritize** — you choose which items to implement now,
rest become a follow-up phase
```
Use AskUserQuestion with these 3 options.
**If "Split":** Use `/gsd:phase --insert` to create the sub-phases, then replan each.
**If "Proceed":** Return to planner with instruction to attempt all items at full fidelity, accepting more plans/tasks.
**If "Prioritize":** Use AskUserQuestion (multiSelect) to let user pick which items are "now" vs "later". Create CONTEXT.md for each sub-phase with the selected items.
## § 9c — Handle Source Audit Gaps
When the planner returns `## ⚠ Source Audit: Unplanned Items Found`, it means items from REQUIREMENTS.md, RESEARCH.md, ROADMAP goal, or CONTEXT.md decisions have no corresponding plan.
**Extract from planner return:**
- Each unplanned item with its source artifact and section
- The planner's suggested options (A: add plan, B: split phase, C: defer with confirmation)
**Present each gap to user.** For each unplanned item:
```
## ⚠ Unplanned: {item description}
Source: {RESEARCH.md / REQUIREMENTS.md / ROADMAP goal / CONTEXT.md}
Details: {why the planner flagged this}
Options:
1. Add a plan to cover this item (recommended)
2. Split phase — move to a sub-phase with related items
3. Defer — add to backlog (developer confirms this is intentional)
```
Use AskUserQuestion for each gap (or batch if multiple gaps).
**If "Add plan":** Return to planner (step 8) with instruction to add plans covering the missing items, preserving existing plans.
**If "Split":** Use `/gsd:phase --insert` for overflow items, then replan.
**If "Defer":** Record in CONTEXT.md `## Deferred Ideas` with developer's confirmation. Proceed to step 10.
## § 11a — Filesystem Fallback (Checker)
Fires when the checker's Agent() call comes back without either completion marker (`## VERIFICATION PASSED` / `## ISSUES FOUND`). The spine already computed `DISK_PLANS` before reaching this elaboration.
**If `DISK_PLANS` > 0:** Plans exist on disk; the checker return was empty or truncated (the
Windows stdio hang pattern — the subagent finished but the return never arrived). Display:
```text
◆ Checker return was empty or truncated. {DISK_PLANS} plan(s) exist on disk.
This is a known Windows stdio hang pattern — checker may have completed without returning.
```
Offer 3 options:
1. **Accept verification** — treat as `## VERIFICATION PASSED` and continue to step 13
2. **Retry checker** — re-spawn the checker with the same prompt (return to step 10)
3. **Stop** — exit; user can re-run `/gsd:plan-phase {N}` to resume
**If `DISK_PLANS` is 0:** No plans on disk — something is seriously wrong. Display error and stop.
## § 11 thinking-partner — Thinking Partner For Architectural Tradeoffs
**Thinking partner for architectural tradeoffs (conditional):**
If `features.thinking_partner` is enabled, scan the checker's issues for architectural tradeoff keywords
("architecture", "approach", "strategy", "pattern", "vs", "alternative"). If found:
```
The plan-checker flagged an architectural decision point:
{issue description}
Brief analysis:
- Option A: {approach_from_plan} — {pros/cons}
- Option B: {alternative_approach} — {pros/cons}
- Recommendation: {choice} aligned with {phase_goal}
Apply this to the revision? [Yes] / [No, I'll decide]
```
If yes: include the recommendation in the revision prompt. If no: proceed to revision loop as normal.
If thinking_partner disabled: skip this block entirely.
## § 12.5 — Plan Bounce (Optional External Refinement)
**Skip if:** `--skip-bounce` flag, `--gaps` flag, or bounce is not activated.
**Activation:** Bounce runs when `--bounce` flag is present OR `workflow.plan_bounce` config is `true`. The `--skip-bounce` flag always wins (disables bounce even if config enables it). The `--gaps` flag also disables bounce (gap-closure mode should not modify plans externally).
**Prerequisites:** `workflow.plan_bounce_script` must be set to a valid script path. If bounce is activated but no script is configured, display warning and skip:
```
⚠ Plan bounce activated but no script configured.
Set workflow.plan_bounce_script to the path of your refinement script.
Skipping bounce step.
```
**Read pass count:**

### GSD ► BOUNCING PLANS (External Refinement)
Script: ${BOUNCE_SCRIPT}
Max passes: ${BOUNCE_PASSES}
```
**For each PLAN.md file in the phase directory:**
1. **Backup:** Copy `*-PLAN.md` to `*-PLAN.pre-bounce.md`
```bash
cp "${PLAN_FILE}" "${PLAN_FILE%.md}.pre-bounce.md"
```
2. **Invoke bounce script:**
```bash
"${BOUNCE_SCRIPT}" "${PLAN_FILE}" "${BOUNCE_PASSES}"
```
3. **Validate bounced plan — YAML frontmatter integrity:**
After the script returns, check that the bounced file still has valid YAML frontmatter (opening and closing `---` delimiters with parseable content between them). If the bounced plan breaks YAML frontmatter validation, restore the original from the pre-bounce.md backup and continue to the next plan:
```
⚠ Bounced plan ${PLAN_FILE} has broken YAML frontmatter — restoring original from pre-bounce backup.
```
4. **Handle script failure:** If the bounce script exits non-zero, restore the original plan from the pre-bounce.md backup and continue to the next plan:
```
⚠ Bounce script failed for ${PLAN_FILE} (exit code ${EXIT_CODE}) — restoring original from pre-bounce backup.
```
**After all plans are bounced:**
5. **Re-run plan checker on bounced plans:** Spawn gsd-plan-checker (same as step 10) on all modified plans. If a bounced plan fails the checker, restore original from its pre-bounce.md backup:
```
⚠ Bounced plan ${PLAN_FILE} failed checker validation — restoring original from pre-bounce backup.
```
6. **Commit surviving bounced plans:** If at least one plan survived both the frontmatter validation and the checker re-run, commit the changes:
```bash
gsd_run query commit "refactor(${padded_phase}): bounce plans through external refinement" --files "${PHASE_DIR}/*-PLAN.md"
```
Display summary:
```
Plan bounce complete: {survived}/{total} plans refined
```
**Clean up:** Remove all `*-PLAN.pre-bounce.md` backup files after the bounce step completes (whether plans survived or were restored).
