Supply the required directory collaborator to current runtime fixtures, verify absolute result navigation and deployment fallback, and retain the valid V4 working-directory recording instead of the unreleased V3 input that contains a V4-only event.
Delete @deepseek-ai/dsh-invariants, every package's ./invariant companion
and its tests, the invariant gates and Vitest setup, the scoped-event
resolver generator, and the INVARIANT-coded listener rethrow paths.

Review round 1: the settle assertions build their message only when one
is about to fail, so a passing run never pays the host-facts shell probe;
send windows are bounded by event sequence numbers instead of
milliseconds, so two sends that hand over within one millisecond keep
their own events; the replay starts at the send's own input write and
ignores the emulator's terminal-protocol replies; a throwing foreground
inspection is recorded before the send rejects; a sanitizer is attributed
to the most recently spawned terminal, which the class documents as the
sequential-session assumption. A unit spec pins the replay rule against
the session's evidence states, the window boundaries, the reply/input
distinction, and the bounded, escaped rendering. Notes and comments drop
change narration and the unverified claim about the pool's build.
The self-hosted Windows lane settles one or two of seven sends on the
controlled prompt and the rest at the plain silence bound, and the
settle reasons alone cannot say whether the marker was missing, its tail
was invalidated by later output, or the foreground comparison failed.
The case now records every decoded pty chunk with the sanitizer's marker
verdict and prompt tail, every foreground poll, every input write, each
send's settle reason and elapsed time, the session's prompt evidence
replayed from those chunks, and the host, pwsh, PSReadLine, and console
host versions; the settle assertions carry that timeline in their
failure message and onTestFailed prints it when the runner's budget ends
the case first.
promptTailGraceMs returns to the product default: master runs with and
without it took the same 20.8 s, so the lane's degraded sends never held
the state it covers, and a nonzero value there would only lengthen a
never-arriving-tail fallback.
Review round 1: the tolerance now requires the accumulated tail to remain a
prefix of the controlled prompt, so a prompt that arrived and was invalidated by
later output keeps the plain silence bound instead of waiting a tolerance with
nothing left to wait for. The field is validated as zero or at least one
`pollIntervalMs`, matching the handoff grace rule, and tests pin the extended
bound's expiry, the invalidated tail, and that rule. The owning readiness design
note records the new field and Tier 2 bound and cross-links this decision.
Windows sessions on the self-hosted lane settled one or two of seven sends on
the controlled prompt and charged the silence tier for the rest (issue 2487).
The marker is written by the shell's own prompt function and the printable tail
by the same render, so a tail that arrives past `idleSilenceMs +
handoffGraceMs` means a stalled delivery, not an absent prompt.
`dsh-terminal-bash` gains a validated `promptTailGraceMs` bound (default 0,
which reproduces the previous bound exactly). While a send has seen the marker
and its printable tail has not arrived, the silence bound grows by it. The
pwsh Loader-composition case sets 5000 ms, the host class the bound is for, and
still fails when no marker appears at all.
`operations.spec.ts` read the profile's run record from a 100 ms timer armed
before the refused installation whose repair it observes; a loaded runner
reached the repair run after that timer and the case failed with `null`
against the recorded run. The observing child now stays in flight until the
record appears, and the bounded wait starts at the launcher hand-over rather
than at test start.
The loader-composition case counts `stdin_read` settlements but reported only
the count, so its Windows failures could not say which tier settled which
send. The recorded reasons now ride in the assertion message; the threshold
and the assertions are unchanged.
Add a path-check reminder to the bash and pwsh tool descriptions. pwsh
also warns against assigning automatic variables such as $HOME; bash
also asks agents to guard path variables with ${VAR:?}.
