 # Planning with Files
@@ -240,9 +240,26 @@ When working on multiple tasks in the same repo simultaneously:
 
 # Or pin a terminal to a specific plan
 export PLAN_ID=2026-01-10-backend-refactor
+
+# Or pin a thread to a project root, when the shell's cwd is somewhere else
+export PWF_PLAN_ROOT=/workspace/project
 ```
 
 Each session reads from its own isolated plan directory. Hooks resolve the correct plan automatically.
+
+### Shared parent directories (v3.9.0)
+
+`PLAN_ID` is a slug resolved against the current directory, so it can only ever name a plan under `$(pwd)/.planning`. When an agent thread runs with its cwd at a shared parent (`/workspace`) while the real work lives in a nested project (`/workspace/project`), the parent's plan is the only one the hooks can see, and it used to be injected on every fire. `PWF_PLAN_ROOT` takes an absolute path and pins resolution to that root regardless of where the cwd sits. A pin that does not resolve stops injection rather than falling back.
+
+When no pin is set, the plan was picked by the `.active_plan` pointer or by the newest plan directory, and a project directly below the root carries its own planning state, the hooks treat that as ambiguous and inject nothing:
+
+```
+[planning-with-files] Ambiguous plan: this cwd has an active plan and a nested
+project below it has its own (project). Nothing injected. Pin the thread with
+PWF_PLAN_ROOT=<absolute path> or PLAN_ID=<slug>.
+```
+
+Naming the plan explicitly, with either variable or an attached session, skips that check. Detection looks one directory deep, so a project nested further down is not detected.

+Autonomous mode answers the recitation question: strong models drift less, so the per-tool-call plan re-injection (about 90 tokens per matched tool call, the component that scales with tool use) is dropped.

Eliminating recitation entirely is not supported by evidence.
 
 Gated mode adds the completion gate on top of autonomous behavior. The gate is the termination oracle: it judges the plan artifact on disk, not the conversation transcript, which is why it beats a transcript-bound evaluator that can be hallucinated.

+# --- Parallel-write guard (v3.10.0, issue #217). ---
+# Two sessions sharing one plan directory can both write task_plan.md from the
+# same read: the later write silently discards the earlier one's work, and
+# nothing notices (injection, plan-doctor and the Stop gate all read the
+# clobbered file as an ordinary edit). Attestation does not cover this. It
+# compares against a baseline a human approved once, it reports a collaborator's
+# edit with the same [PLAN TAMPERED] wording as a hostile rewrite, and it is a
+# read-side gate that cannot stop the stale write from landing.
+#
+# Comparing the raw hash against "what the hooks last saw" would flag a single
+# agent's own edit on its very next fire, which is most fires. This compares
+# PROGRESS instead: checked boxes and completed phases only go up during normal
+# work, so a DECREASE between two fires means work that was on disk is gone.
+# Forward motion stays silent, which is what keeps the signal worth reading.
+# Both markers are language-neutral: every translated template keeps the literal
+# English "**Status:** complete" token because check-complete.sh matches it with
+# grep -F.
+#
+# Advisory only, and userprompt only. This script contracts to always exit 0,
+# and no PreToolUse deny path exists on any supported host, so the guard reports
+# the loss it can see rather than pretending to prevent it.
+#
+# Default-on everywhere, including legacy, and that is a deliberate narrow
+# exception to the "no .mode file means byte-identical output to v2.43"
+# invariant above. Arming it only in a v3 mode would arm it exactly where it is
+# redundant and leave it off where the bug bites: a v3 mode refuses to inject an
+# UNATTESTED plan at all (NEEDS_ATTEST, above), and an ATTESTED one already
+# reports an outside edit as TAMPERED, so the unprotected population is legacy,
+# which is also the default. The invariant exists so the injected plan payload
+# stays stable turn over turn, not so that destroyed work stays silent, and this
+# line appears only when work was destroyed. PWF_PLAN_GUARD=0 or a
+# "plan-guard-off" token in .mode restores the old silence.
+#
+# ponytail: the marker is keyed on the plan path, not the session, so the

+# This script holds the logic that used to live inline in the UserPromptSubmit,
+# PreToolUse, and PreCompact hook command scalars (v2.43 and earlier). The hooks
+# now dispatch to this file via the proven self-discovery pattern, so the logic
+# is versioned and testable instead of duplicated across 14 SKILL.md variants.
+#
+# Context modes (--context=...):
+#   userprompt (default) — full plan head + progress/ledger summary. Once per turn.
+#   pretool              — short plan head only (head -30), no progress.
+#   precompact           — compaction reminder only (no plan body), matches v2.
+#
+# v3 behavior keys off explicit opt-in. With no .mode file present the output is
+# byte-equivalent to the v2.43 hook scalars (legacy invariant). Autonomous and
+# gated modes change the injection shape (full fidelity + structured ledger
+# summary instead of raw progress.md tail; per-tool-call injection dropped).

+# planning-with-files: emit a fixed-shape, cache-stable run-ledger summary (v3).
+#
+# This replaces raw `tail -20 progress.md` injection in autonomous mode. The
+# output is synthesized from the machine ledger and task_plan.md status counts
+# only: NO free text from disk reaches the model context, and there are NO
+# timestamps, so the injected block is KV-cache stable by construction
+# (architecture C3 injection rule).
+#
+# Plan-dir resolution:
+#   0. Explicit plan-dir argument (issue #212, see below)
+#   1. $PLAN_ID env var -> ./.planning/$PLAN_ID/   (via resolve-plan-dir.sh)
+#   2. ./.planning/.active_plan                    (via resolve-plan-dir.sh)
+#   3. Newest ./.planning/<dir>/ by mtime          (via resolve-plan-dir.sh)
+#   4. Legacy: project root
+#
+# Usage:
+#   sh scripts/ledger-summary.sh [plan-dir]
+#
+# The optional argument is the caller's already-resolved plan directory and
+# wins over self-resolution: inject-plan.sh passes the dir it resolved,
+# because a cwd-based re-resolution here would pair a PWF_PLAN_ROOT-pinned
+# plan's body with the PARENT project's phase counts and agent events — a
+# false termination signal for an autonomous loop. No argument keeps the
+# self-resolution above unchanged.
+#
+# Output block (stable shape):
+#   === RUN LEDGER ===
+#   entries: <N>
+#   phases: <complete>/<total> complete
+#   in_progress: <phase heading or none>
+#   agent <name>: <last event type>
+#   ...
+#   ==================
+#
+# When no plan directory is determinable at all (argument names a missing dir,

+.SYNOPSIS
+    Lock the current task_plan.md content with a SHA-256 attestation.
+
+.DESCRIPTION
+    Use after you finalise (or intentionally edit) a plan. The hooks then refuse
+    to inject plan content into the model context if the file diverges from the
+    attested hash, surfacing a "[PLAN TAMPERED]" warning instead.
+
+    Plan resolution:
+      1. $env:PLAN_ID  -> ./.planning/$PLAN_ID/
+      2. ./.planning/.active_plan
+      3. Newest ./.planning/<dir>/ by LastWriteTime
+      4. Legacy ./task_plan.md at project root
+
+.PARAMETER Show
+    Print the stored hash for the active plan.
+
+.PARAMETER Clear
+    Remove the attestation (re-open the plan).

+# planning-with-files: resolve the active plan, verify its attestation, and emit
+# plan context for injection into the model turn.
+#
+# This script holds the logic that used to live inline in the UserPromptSubmit,
+# PreToolUse, and PreCompact hook command scalars (v2.43 and earlier). The hooks
+# now dispatch to this file via the proven self-discovery pattern, so the logic
+# is versioned and testable instead of duplicated across 14 SKILL.md variants.
+#
+# Context modes (--context=...):
+#   userprompt (default) — full plan head + progress/ledger summary. Once per turn.
+#   pretool              — short plan head only (head -30), no progress.
+#   precompact           — compaction reminder only (no plan body), matches v2.
+#
+# v3 behavior keys off explicit opt-in. With no .mode file present the output is
+# byte-equivalent to the v2.43 hook scalars (legacy invariant). Autonomous and
+# gated modes change the injection shape (full fidelity + structured ledger
+# summary instead of raw progress.md tail; per-tool-call injection dropped).
+#
+# Multi-root disambiguation (issue #212): PWF_PLAN_ROOT pins the effective plan
+# root for threads whose cwd is a shared parent of the real project; a
+# .planning/sessions dir arms the same session-attachment guard the Codex
+# adapter enforces; and an ambiguous cwd-guessed resolution refuses to inject
+# when a direct child of the root carries its own competing .planning.

+#   3. Newest ./.planning/<dir>/ by mtime          (via resolve-plan-dir.sh)
+#   4. Legacy: project root
+#
+# Usage:
+#   sh scripts/ledger-summary.sh [plan-dir]
+#
+# The optional argument is the caller's already-resolved plan directory and
+# wins over self-resolution: inject-plan.sh passes the dir it resolved,
