From 7906854605eefb38e734e8a36fd8a8bea897699f Mon Sep 17 00:00:00 2001 From: fujibee Date: Sun, 30 Aug 2026 10:16:36 +0900 Subject: [PATCH 01/67] =?UTF-8?q?feat(terminals):=20add=20the=20terminal-d?= =?UTF-8?q?river=20axis=20=E2=80=94=20registry,=20record=20scheme,=20and?= =?UTF-8?q?=20tmux/herdr/plain=20drivers=20(#terminal-driver=20v1,=20PR1)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New driver axis "terminals": the ONE terminal a member's CLI runs under (tmux, herdr, or plain), behind a locked ABI, so the terminal operations currently inlined as $TMUX / HERDR_* branches across spawn/despawn/watch can move behind a contract and peek/poke can be added. This PR is new files only — nothing existing is rewired yet (that is PR2/PR3), so no existing behavior can regress. Contract (5 verbs + terminal_name, per docs/spec/driver-interface.md): terminal_check / terminal_describe ABI-required (deps, metadata) terminal_detect RECORD op: ONE observation returns BOTH which terminal we are under AND this session's own pane id. Deliberately not two ops: splitting them lets state change between the two observations (the defect shape corrected three times the same night — _wait_role_count, #1008's four reads). herdr resolves the pane from the session id via `agent list` (inherited HERDR_PANE_ID is NOT trusted); tmux uses $TMUX_PANE; plain is the exit-0 fallback. terminal_spawn / despawn / peek / poke / name Registry (scripts/lib/terminal-registry.sh): a terminals facade over driver-registry.sh. terminal.conf is DATA read by a clone of agmsg_type_get; ops.sh is sourced into the caller. Resolution: --terminal / AGMSG_TERMINAL > detection (order herdr > tmux > plain, so it never fails) — the single answer that ends the historical $TMUX-vs-HERDR_* dual system; detection sources each candidate in a subshell so terminal_* definitions do not clobber across candidates. Record ref is :; reading tolerates the pre-axis forms (a bare %N/@N reads as tmux, the old herdr: still reads as herdr; first-colon split so a herdr id's own ':' survives). Drivers: tmux (faithful to the pre-axis argv), herdr, plain (peek/poke/despawn/ name -> status 13 unsupported, reason on stderr). plain's detect is the fallback. Tests (tests/test_terminal_registry.bats, 18): resolution incl. precedence and order, record scheme incl. legacy/inner-colon, conf reader, and every driver op against fake tmux/herdr binaries that record argv. The fake binaries record that a binary was CALLED, not that the RIGHT driver was selected — so the resolution tests assert the returned terminal NAME, and a selection->op test loads the resolved terminal and asserts the op reaches the herdr binary and never tmux, so a wrong selection cannot pass as "argv as expected". Mutation-verified: a single-burst text+Enter poke (dropping the #619 arrow), and a tmux-before-herdr detection order (which reddens both the order test and the selection->op test), each redden their test. MEASURED vs ASSERTED (herdr): the pre-axis calls (pane split/rename/run, tab create, pane close), `agent list` being JSON, name encoding team__name, and `pane read --source visible` are grounded in seat-0 measurements and the existing tree. The EXACT argv of `herdr agent prompt` (poke) and the `agent list` JSON field names used to extract the pane (agent_session / pane_id) are asserted from the assignment brief and verified only by the live matrix on the real CLI, not here; the fixtures pin the control flow and the argv this driver emits, so a real-CLI mismatch is a localized one-line fix the matrix catches. Source of the scope (no committed scope/naming-map doc exists): the assignment messages, the seat-0 measurements, and the existing code + driver ABI. --- scripts/drivers/terminals/herdr/ops.sh | 142 ++++++++++ scripts/drivers/terminals/herdr/terminal.conf | 8 + scripts/drivers/terminals/plain/ops.sh | 32 +++ scripts/drivers/terminals/plain/terminal.conf | 11 + scripts/drivers/terminals/tmux/ops.sh | 111 ++++++++ scripts/drivers/terminals/tmux/terminal.conf | 7 + scripts/lib/terminal-registry.sh | 188 +++++++++++++ tests/test_terminal_registry.bats | 265 ++++++++++++++++++ 8 files changed, 764 insertions(+) create mode 100644 scripts/drivers/terminals/herdr/ops.sh create mode 100644 scripts/drivers/terminals/herdr/terminal.conf create mode 100644 scripts/drivers/terminals/plain/ops.sh create mode 100644 scripts/drivers/terminals/plain/terminal.conf create mode 100644 scripts/drivers/terminals/tmux/ops.sh create mode 100644 scripts/drivers/terminals/tmux/terminal.conf create mode 100644 scripts/lib/terminal-registry.sh create mode 100644 tests/test_terminal_registry.bats diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh new file mode 100644 index 000000000..61c988ec7 --- /dev/null +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -0,0 +1,142 @@ +#!/usr/bin/env bash +# herdr terminal driver — a pane inside a herdr session. +# +# Sourced by the terminals registry into the caller's context. terminal_* only, +# no set -e/-u. +# +# MEASURED (seat 0, 2026-08-29) vs ASSERTED-pending-live-matrix: +# measured: `herdr agent list` is JSON; the pane is resolved from it by the +# session id (inherited HERDR_PANE_ID is NOT trusted); name encoding +# / -> team__name ('/' is not in herdr's name regex); the +# existing spawn/despawn calls (pane split/rename/run, tab create, pane close). +# asserted (exact argv/JSON fields verified only by the live matrix on koit's +# machine, NOT measured here): the `agent list` JSON field names used to +# extract the pane (agent_session / pane_id), `herdr agent prompt`'s argv for +# poke, and `herdr pane read --source` for peek.

charset=UTF-8 Content-Transfer-Encoding: 8bit co1's four groups + two follow-ups: (1) ABI completeness / clobber. plain declared capabilities=spawn but ops.sh had no terminal_spawn; and switching drivers left the previous driver's ops in the shell. Now: plain implements terminal_spawn as a faithful driver-ification of the OS-terminal launch (returns '-', no addressable pane); despawn/peek/poke/ name stay unsupported. And agmsg_terminal_load is structurally clobber-proof — it unsets ALL terminal_* before sourcing and VERIFIES every required ABI function is defined after, so an incomplete driver fails loudly instead of borrowing a leftover. The required set is named ONCE (_AGMSG_TERMINAL_REQUIRED) and reused by both the loader and the detect subshell, which also unsets the same set so a candidate missing terminal_detect cannot be judged by an inherited one. On verify failure nothing partial is left behind. (2) fail-closed resolution. tmux terminal_detect now requires a non-empty $TMUX_PANE ($TMUX alone is not a match — no invalid 'tmux:' record). The resolver requires a non-empty self id for an auto-detect match, and an override that names no real driver fails loudly instead of resolving to '\t' (agmsg_terminal_dir existence check). (3) prose. herdr comments now put 'pane read --source' on the MEASURED side (seat 0 measured the --source values), matching the PR body; only 'agent prompt' argv and the agent-list JSON field names stay ASSERTED. (4) no new ambient config surface (the #1004 lesson). The tmux/herdr split direction moved from AGMSG_TMUX_SPLIT / AGMSG_HERDR_SPLIT into the op's argument (window | pane-h | pane-v). poke's gap and arrow are no longer env knobs (AGMSG_POKE_GAP / AGMSG_POKE_ARROW removed) — the gap is part of the behavior, the arrow is hardcoded Right. Naming note flagged to tl: the resolver override env is AGMSG_TERMINAL_DRIVER, NOT AGMSG_TERMINAL — the latter is already the OS-terminal command template read by plain's spawn, so reusing it would collide. Tests: 25 total. Added ABI-completeness (every driver defines every required verb; capabilities= verbs are implemented), structural clobber (tmux->plain runs plain's ops, not tmux's; an incomplete external driver fails the load leaving nothing behind), fail-closed (empty $TMUX_PANE is not tmux; a typo override fails loudly), and plain OS-terminal spawn. Mutation-verified: skipping the ABI verification and skipping the override existence check each redden their test. --- scripts/drivers/terminals/herdr/ops.sh | 24 +++--- scripts/drivers/terminals/plain/ops.sh | 71 ++++++++++++++--- scripts/drivers/terminals/tmux/ops.sh | 55 +++++++------ scripts/lib/terminal-registry.sh | 67 +++++++++++++--- tests/test_terminal_registry.bats | 104 +++++++++++++++++++++++-- 5 files changed, 261 insertions(+), 60 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 61c988ec7..f2bd897d4 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -7,14 +7,15 @@ # MEASURED (seat 0, 2026-08-29) vs ASSERTED-pending-live-matrix: # measured: `herdr agent list` is JSON; the pane is resolved from it by the # session id (inherited HERDR_PANE_ID is NOT trusted); name encoding -# / -> team__name ('/' is not in herdr's name regex); the -# existing spawn/despawn calls (pane split/rename/run, tab create, pane close). +# / -> team__name ('/' is not in herdr's name regex); the existing +# spawn/despawn calls (pane split/rename/run, tab create, pane close); and +# `pane read --source ` (seat 0 measured the --source values). # asserted (exact argv/JSON fields verified only by the live matrix on koit's # machine, NOT measured here): the `agent list` JSON field names used to -# extract the pane (agent_session / pane_id), `herdr agent prompt`'s argv for -# poke, and `herdr pane read --source` for peek.

Test uses a fixture that defines functions then returns non-zero (a parse error would define nothing and not exercise this) — mutation-verified. - (3) herdr spawn target validation. An unknown target is now status 13 (a typo no longer silently becomes pane-v); a window target without HERDR_WORKSPACE_ID fails explicitly instead of silently splitting a pane. Both pinned + one mutation-verified. Scope alignment: - plain implements spawn/despawn (scope: "plain implements spawn/despawn"). Its terminal_spawn is a faithful move of spawn.sh's OS-terminal launchers ({cmd} template wins on any OS; macOS current-terminal / app hint; Linux/Windows reject a template without {cmd} and reject headless / unknown OS), returning '-' (no addressable pane). terminal_despawn is a no-op ok (an OS window has no handle; it closes with its process, as before the axis). peek/poke/name stay unsupported. The launch template reads AGMSG_TERMINAL (its EXISTING meaning), which is distinct from the resolver override AGMSG_TERMINAL_DRIVER — no collision. - terminal_name follows the scope's Naming section: canonical separator ':' (both team and agent commonly contain '-'). tmux sets a pane user option @agmsg_agent=: as the RESOLVABLE key (tmux is never targeted by name — '-t a:b' is session:window) plus select-pane -T as the visible copy. herdr does a visible `pane rename :` plus an internal `agent rename` with the label folded to herdr's [a-z][a-z0-9_-]{0,31} agent-name regex. Open for tl: the override env is AGMSG_TERMINAL_DRIVER, not AGMSG_TERMINAL (scope names the latter, but it is already the OS-terminal template) — a contract decision raised with tl.

Contract said one thing, code did another — aligned to the code (the final contract): - plain/terminal.conf's HEADER still carried the reverted "spawn/despawn unsupported, no capability, OS launch stays in spawn.sh" text directly above `capabilities=spawn despawn`. Removed the stale header; plain SPAWNS an OS window and DESPAWNS as a no-op, per the scope. - The resolver override is AGMSG_TERMINAL_DRIVER (a NEW surface), not the existing --terminal / AGMSG_TERMINAL (which stay the OS-terminal command template, untouched) — tl's ruling 2026-08-31 ("a new axis gets a new name"). The error message no longer calls arg2 "--terminal". - The override is documented as a spawn/name resolution PREFERENCE: ops on an existing member (despawn/peek/poke) read the terminal from the placement record, never the env, so a forced driver whose detect fails still resolves (driver + empty id) — "spawn into tmux" is valid off-tmux, and a record's terminal is never overridden by an inherited env (scope L96-98; tl leaning). 2. The plain template test now proves the BOOT reaches execution THROUGH the {cmd} template: the fake boot records that IT ran, so a dropped/garbled {cmd} leaves the marker absent (mutation-verified red) instead of the old "touch a marker, ignore {cmd}" that passed regardless. 3. terminal_name's `herdr agent rename ` is a new exact argv with no existing measured path in main — added to the ASSERTED (pending-live-matrix) list in the driver header, alongside agent prompt and the agent-list fields. Tests: 29, all green; enforced-assertions at baseline 635.

Control: force mktemp to fail under set -e; the caller still reaches the non-zero verdict. 3. herdr detect distinguishes THREE states, as its comment (and tl's ruling) claim: _herdr_pane_for_session now returns 2 for "could not answer" (herdr absent / list errored), 0+pane for a match, and 0+empty for "answered but this session is not among the live agents" — the last was previously unreachable (both collapsed to return 1). Controls assert the two reasons differ.

How submission happens is the driver's contract: tmux sends the text and, in a separate later burst, an arrow key + Enter (#619 — same-burst text+Enter is classified as a paste and the Enter becomes a newline); herdr's agent prompt submits by itself. Multi-word unquoted text is refused rather than silently truncated, and a missing record refuses before any terminal binary runs. Tests pin the argv SHAPE against fake tmux/herdr binaries: exactly two tmux invocations, the first the literal text with no Enter (asserted by whole-line equality, so an Enter rejoining the text burst goes red — verified by mutating the driver to a single burst and watching the test fail), the second Right+Enter; herdr exactly one invocation with the inner-colon pane id intact. What argv cannot see, and the live matrix must: the inter-burst gap (a sleep) and whether the real Codex reads the result as a submission.

Statements between `set +e` and `set -e` are not reported: that lift is the accepted fix (agmsg_terminal_load), and a checker that flagged the fix could never be burned down. It cannot pass by failing to look. Before reading the tree it scans a fixture holding one known-bad instance of each kind and requires all three back, plus the two correct forms absent; a scanner that stops matching exits 2 (could not answer) instead of 0 (found nothing). Verified by mutation: breaking the assignment regex gives exit 2, not a green run. Wired into tests.yml as its own unconditional job, for the same reason the enforceable-assertions job is unconditional. Baseline is 2 — the two live instances in the herdr driver, which the checker found on its own run rather than being told about. Surface: `/agmsg peek ` and `/agmsg poke ` documented in all 9 type templates, identical text in each (one anchor, verified 9/9 by block hash), and `delivery.sh status` now names the resolved terminal in three distinguishable states — resolved with a pane, present but unable to identify this pane, and unknown. The middle one is printed separately because it is the state where naming and peeking fail while everything else looks fine. --- .github/errexit-status-reads-baseline | 1 + .github/scripts/check-errexit-status-reads.sh | 248 ++++++++++++++++++ .github/workflows/tests.yml | 18 ++ scripts/delivery.sh | 57 +++- scripts/drivers/types/antigravity/template.md | 14 + scripts/drivers/types/claude-code/template.md | 14 + scripts/drivers/types/codex/template.md | 14 + scripts/drivers/types/copilot/template.md | 14 + scripts/drivers/types/cursor/template.md | 14 + scripts/drivers/types/gemini/template.md | 14 + scripts/drivers/types/grok-build/template.md | 14 + scripts/drivers/types/hermes/template.md | 14 + scripts/drivers/types/opencode/template.md | 14 + 13 files changed, 449 insertions(+), 1 deletion(-) create mode 100644 .github/errexit-status-reads-baseline create mode 100755 .github/scripts/check-errexit-status-reads.sh diff --git a/.github/errexit-status-reads-baseline b/.github/errexit-status-reads-baseline new file mode 100644 index 000000000..0cfbf0888 --- /dev/null +++ b/.github/errexit-status-reads-baseline @@ -0,0 +1 @@ +2 diff --git a/.github/scripts/check-errexit-status-reads.sh b/.github/scripts/check-errexit-status-reads.sh new file mode 100755 index 000000000..5ec92ada0 --- /dev/null +++ b/.github/scripts/check-errexit-status-reads.sh @@ -0,0 +1,248 @@ +#!/usr/bin/env bash +# +# Fail when a script grows a `$?` read that errexit never lets it reach — or +# that it reaches only to find a 0 that means nothing. +# +# Measured, not assumed.

Any literal separator collides because it is legal inside a name (validate.sh forbids only . / \ " [ ] control chars and a leading -), so ("a-b","c") and ("a","b-c") folded to the same internal key, and ("a:b","c")/("a","b:c") would too. Derive instead: 'a' + first 24 hex of sha256("\n"); newline is a control char and thus forbidden in both names, so the join is unambiguous and the key is injective. The key satisfies herdr's [a-z][a-z0-9_-]{0,31}. Visible names (pane rename, report-metadata) stay the free-text :. Uses the store's canonical agmsg_sha256 (lib/hash.sh), sourced relative to the driver; a missing SHA-256 tool leaves the best-effort internal rename skipped, not fatal. terminal-registry resolve_name: the loop's detect assignment was a bare `id="$(...)"; rc=$?`, which under bash 3.2 set -e aborts the caller the instant a candidate is not the current terminal (the common case), before trying the next. Move it to conditional context (`rc=0; id="$(...)" || rc=$?`), same class as the herdr helper fix. tests: assert the naming key is injective for the '-' and ':' fold-collisions (distinct outputs, not merely "a key is produced"); a bare-call errexit control that requires the verdict line to PRINT (not just status) under /bin/bash 3.2; a positive-proof control that exit-0 invalid JSON classifies as did-not-answer, not no-match. 36 green; enforced-assertions at baseline 635. --- scripts/drivers/terminals/herdr/ops.sh | 98 +++++++++++++++++++------- scripts/lib/terminal-registry.sh | 7 +- tests/test_terminal_registry.bats | 75 +++++++++++++++++--- 3 files changed, 146 insertions(+), 34 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 55c4f330d..8e194b161 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -6,10 +6,11 @@ # # MEASURED (seat 0, 2026-08-29) vs ASSERTED-pending-live-matrix: # measured: `herdr agent list` is JSON; the pane is resolved from it by the -# session id (inherited HERDR_PANE_ID is NOT trusted); name encoding -# / -> team__name ('/' is not in herdr's name regex); the existing -# spawn/despawn calls (pane split/rename/run, tab create, pane close); and -# `pane read --source ` (seat 0 measured the --source values). +# session id (inherited HERDR_PANE_ID is NOT trusted); the internal agent-name +# key is an injective SHA-256 derivation of (team, agent) — see +# _herdr_internal_key for why concatenation/folding is not injective; the +# existing spawn/despawn calls (pane split/rename/run, tab create, pane close); +# and `pane read --source ` (seat 0 measured the --source values). # asserted (exact argv/JSON fields verified only by the live matrix on koit's # machine, NOT measured here): the `agent list` JSON field names used to # extract the pane (agent_session / pane_id), `herdr agent prompt`'s argv for @@ -43,23 +44,41 @@ terminal_describe() { # return 0, empty — answered, but this session is not among the live agents _herdr_pane_for_session() { local sid="$1" json rc=0 - json="$(herdr agent list 2>/dev/null)"; rc=$? + # `|| rc=$?` (not `; rc=$?`): a bare command-substitution assignment fires the + # caller's set -e the instant the command fails, so the next line never runs and + # the "could not answer" case can't be classified.

This calls the naming step from the three moments a session takes on an identity, and writes the same `:` record spawn writes, so being addressable no longer depends on who launched the pane. SessionStart is not redundant with the other two: herdr drops an agent's name when the agent exits, so a resumed session is nameless until it is re-applied. One shared function rather than the same fifteen lines in three scripts — `agmsg_terminal_name_self` in the registry, with the callers reduced to a line each. Two forms of one step is how a migration ends up half-applied. Three outcomes, deliberately not folded together: named the terminal can name a pane and this pane was identified: the driver names it, and the record is written afterwards, never before. skipped quiet, 0, no record. Two ways to reach it: the terminal has no `name` capability (plain has no addressable pane), or no session id was supplied at all. A record whose id cannot be acted on is not a placement. unnamed the terminal can name, a session id WAS given, and the pane still could not be identified: non-zero with the resolver's reason. The last distinction is why `join` can call this at all. join has no session id to give — nothing says which env var carries one for a given type (filed separately) — and "no input to resolve with" is a different fact from "the lookup failed". Reported as the latter it would warn on every join under herdr about a condition nobody can act on; reported as the former, tmux still names the pane (it needs no session id) and herdr waits for actas or SessionStart, which have one. Callers treat a non-zero as a warning and never as a failure of the join, claim or session start they are performing: naming is additive and must not change what those commands do. Each source of the registry carries the errexit lift, because on bash 3.2 a failure inside a sourced file fires the CALLER's `set -e` — a plain `. x || true` would take the join down rather than skip the naming. Capability is read from `terminal.conf`, not tested against the driver's name, so a terminal that grows the ability later needs no change here. Measured, not assumed: run inside a throwaway tmux server (private socket), a join under this branch is currently `skipped` rather than `named`, because `resolve_name` stops at the first terminal that claims presence and herdr claims it — through inherited HERDR_* env — while returning no pane id, so tmux is never asked although it answers `%0`. That is the resolver's short-circuit, reported separately; this layer behaves correctly on both sides of it. Existing tests unchanged and green: actas_lock 22, actas_integration 14, role_session 24.

The mock returned a scalar and was green while resolving zero panes. Fixes, all in cc3's files: herdr/ops.sh _herdr_pane_for_session: - Compare .agent_session.value (measured against herdr 0.8.0, read-only), and query $.result.agents first (the measured wrapper), keeping the others as fallbacks. - SCHEMA GATE (co1): a successful json_each is not proof of a recognized list — json_each on a valid {} returns 0 rows and would misclassify an unknown schema as "answered, not among". Confirm json_type(path)='array' before json_each; count a path as queried only when a real array existed. {}/{"unknown":[]} -> did-not-answer; only a valid empty ARRAY -> not-among. - Drop the trailing ';' from the single-statement sqlite SQL: it is unnecessary, and the errexit-status-reads checker's statement splitter breaks a line at a ';' inside the SQL string, false-flagging the correct `|| rc=$?` form as a bare read. herdr/ops.sh terminal_name key: narrow the contract wording from "injective" to COLLISION-RESISTANT (co1: a 96-bit hash of arbitrary input has collisions by pigeonhole). Newline framing removes the structural '-'/':' ambiguity; uniqueness is only needed among the dozens of live agents; on the vanishing chance of a collision, `agent rename` fails non-fatally and the pane record still resolves. Test 19 pins that the known fold/join collisions do not recur, not injectivity. terminal-registry resolve_name ORDER (tl, from cc1's nested measurement): prefer a candidate that produced a nameable id over one that only claimed presence; declaration order (herdr>tmux>plain) is the tiebreak among id-producers. A nested herdr-in-tmux makes herdr claim presence though tmux is the real terminal — record tmux:. Fatal only when no candidate produced a nameable id AND a non-plain candidate was present-but-unresolved, printing EVERY such reason — so a genuinely broken herdr fails LOUDLY instead of falling through to plain's '-' silently. Tests: real-shape fixture + scalar-shape drift guard; unknown-schema both-sides; nested/broken-both-reasons/declaration-order controls. 42 green; errexit baseline 1, enforced-assertions 635.

The From 7142e23220b3d34db1dad678e482f031ccc5d8b3 Mon Sep 17 00:00:00 2001 From: fujibee Date: Wed, 2 Sep 2026 07:05:43 +0900 Subject: [PATCH 23/67] fix(ci): the errexit checker was cutting statements at a `;` inside a quoted string MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit cc3 hit it on herdr/ops.sh and worked around it by deleting a trailing `;` from a SQL string. The workaround is harmless; the false positive is not. A checker that reports the correct form gets routed around, and the next person routes around it without saying so — at which point it passes while guarding nothing. Two bugs, both now covered by controls that run on every invocation: 1. The splitter worked line by line, so a double-quoted SQL string that opened on one line and closed on another left its `;` looking like a statement separator. `x="$(sqlite3 ... "SELECT ...;" )" || rc=$?` was cut in half and its `|| rc=$?` guard vanished, so the correct form was reported as bare. Quote and `$( )` state now carry across newlines. A command substitution opens a FRESH quoting context even inside double quotes, so the quote char is pushed on `$(` and restored on `)`. Modelling that as a flat flag is what made the first attempt swallow a REAL instance instead — the `"` right after `$(` read as closing the outer string. The control caught that before it shipped, which is what the control is for. 2. A statement that merely CONTAINS `$?` was treated as a status read, so the `|| vrc=$?` on a guarded assignment made the checker report the innocent line above it. A status read is now an assignment whose whole value is `$?`. Controls added (failing any of them exits 2, not 0): - a multi-line SQL assignment with `|| rc=$?` must NOT be reported - the same multi-line SQL shape WITHOUT a guard must still BE reported, by name — otherwise the fix buys a false negative in place of a false positive Verified by mutation: reverting to the per-line splitter now exits 2. The count stayed at 1 while its content changed completely, which is the shape worth naming: the old scanner's single finding was the herdr false positive; the new one's is scripts/remote.sh:1086, a genuine [bare] assignment continued with a backslash across two lines that the per-line splitter could never see.

Split "could not read this entry" from "this entry has no session": an entry is DECIDABLE if it is an object that either has NO agent_session (a bare pane — definitely not the target) or an agent_session object with a text .value. not-among requires every entry decidable; an agent_session that is present-but-malformed (scalar, or object without a text .value) is indeterminate -> did-not-answer. One CTE now yields alen, the decidable count, a "target found but pane-id unusable" count (-> did-not-answer, e.g. a matching entry with a numeric/'|' pane_id), and the grammar-constrained matched pane (the only free-text field, so the '|'/one-line framing stays safe). tests: a bare pane + absent target -> not-among; a bare pane + present target -> resolves; the tightened grammar rejects w:p / w1:p / w:p4 / w1:x:p4 and still accepts the measured w1:p4 and the fixture wC:p4.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two changes. (1) co1: the early validation accepted any spawn-capable driver (agmsg_terminal_dir + capabilities=spawn), but place_and_launch dispatches only tmux|herdr|plain — an external driver would pass at parse time and die after the pre-join with a default-arm "cannot place". Derive the early accept-set from the SAME public list: a `case tmux|herdr|plain` at parse time. Generalizing to arbitrary spawn-capable drivers is the launcher->driver reroute's scope; until then early and late agree. (2) Reroute tmux placement THROUGH the tmux terminal driver (first step of the launcher->driver reroute). launch_in_tmux keeps its spawn-level policy (the `command -v tmux` pre-check and message, and the Windows psmux `bash -l` boot wrap), maps --window/--split to the driver's window/pane-h/pane-v target, then calls terminal_spawn and records placement as : via agmsg_terminal_ref (tmux:%N / tmux:@N). despawn already reads the terminal from the record and still tolerates the pre-axis bare %N/@N.

Not observing the caller's pane is not evidence the ambient target is the caller. So a pane split now requires $TMUX_PANE: absent -> return 13 WITHOUT calling split-window (positive proof, no guess). A window target does not need it and is unchanged. This tightens the placement contract post-#990: pane placement needs a target identity, so terminal_spawn refuses with an explicit reason when it has none (resolve_placement may still select tmux; the driver declines rather than guess). tests: $TMUX_PANE set -> split-window carries -t ; unset + pane target -> 13 and no split-window call; window target + unset -> success. The registry and test_spawn tmux tests now set $TMUX_PANE (tmux sets it in every real pane), matching reality. 62 registry green. --- scripts/drivers/terminals/tmux/ops.sh | 18 +++++++++--------- tests/test_spawn.bats | 14 +++++++------- tests/test_terminal_registry.bats | 20 +++++++++++++++++--- 3 files changed, 33 insertions(+), 19 deletions(-) diff --git a/scripts/drivers/terminals/tmux/ops.sh b/scripts/drivers/terminals/tmux/ops.sh index ae18d53a1..4c79e58e8 100644 --- a/scripts/drivers/terminals/tmux/ops.sh +++ b/scripts/drivers/terminals/tmux/ops.sh @@ -69,16 +69,16 @@ terminal_spawn() { pane-h|pane-v) case "$target" in pane-h) dir=-h ;; *) dir=-v ;; esac # #990: split the CALLER's pane, not the attached client's active window.

A tmux member could fold itself away; a herdr member could not — an asymmetry with no cause but the multiplexer the code was written against, and one the v1 scope named as a thing to remove. It now reads the placement record and calls that terminal's `terminal_despawn`, the same route despawn.sh already takes. It does NOT fall back to $TMUX_PANE when the record is unusable. Keeping the fallback would leave tmux on a private path and reinstate the asymmetry — and hide it, because the one terminal that still worked is the one nobody would notice was special. It does NOT fold a pane it cannot show is its own. despawn.sh tears down somebody else from a record; this path tears down ITSELF, and the two need different proof. A record for (team, name) says a pane was placed for that seat — never that this process is running in it. So the record's terminal and id must equal what this session resolves to right now, and every shortfall is reported rather than guessed past.

A terminal knows what the CLI told it at SessionStart, which is the bare sid (herdr stores exactly that in agent_session.value). Handing over the composite asks a question no terminal can answer, and the failure reads as "cannot identify its own pane" — a resolution problem in appearance, an identifier mismatch in fact. The herdr test found this; it was not visible from the code. Four tests, terminals stubbed on PATH so nothing here can close a real pane (this suite has closed a developer's session once already — see the setup note).

Measured before fixing, on bash 5.3 and /bin/bash 3.2: a bare call of the function dies silently with no message on both; through today's sole caller the message DOES appear, because that caller's '|| exit 1' disables errexit inside the substitution too — an accident of invocation, not a property of the function. After the fix (status=0; out=$(...) || status=$?) the message reaches the operator in every calling context on both shells, and the function no longer depends on how it is called for its own error report to exist. The errexit-status-reads baseline drops 1 -> 0: this was the checker's last entry (after 7142e23 taught its splitter about backslash continuations, which is how this line surfaced at all). The live-path test 'pull: a truly unreachable server is reported as such (#726)' covers the message through the real caller and stays green on both shells; from here the checker itself is the regression guard, at zero. --- .github/errexit-status-reads-baseline | 2 +- scripts/remote.sh | 11 +++++++++-- 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/.github/errexit-status-reads-baseline b/.github/errexit-status-reads-baseline index d00491fd7..573541ac9 100644 --- a/.github/errexit-status-reads-baseline +++ b/.github/errexit-status-reads-baseline @@ -1 +1 @@ -1 +0 diff --git a/scripts/remote.sh b/scripts/remote.sh index 4e6c2db02..352ee056a 100644 --- a/scripts/remote.sh +++ b/scripts/remote.sh @@ -1081,9 +1081,16 @@ _remote_resolve_team_id() { # malformed candidate -- and it needs to reach the operator, not get # replaced by a single line that names two different causes at once and # lets the reader guess which one happened. + # The status is captured ON the assignment, not read bare on the next line: + # under errexit a bare failing assignment ends the shell before either the + # `status=$?` or the message below it (#1025).

On anything short of that, --force keeps the record, the registration and the lock, and reports status=error note=force-teardown-unconfirmed (non-zero) instead of a false status=forced. Also update the despawn.sh header prose to the final contract: graceful teardown folds tmux AND herdr members through the driver (not tmux-only), and --force confirms before dropping anything. tests: a confirmed teardown (stubbed kill-pane exit 0) -> forced, record cleaned; an unconfirmed one (kill-pane exit 1) -> status=error, record KEPT, registration NOT dropped; a corrupt ref -> status=error, record KEPT.

A line continuation was split. `. \` + newline + `"$dir/ops.sh"` became two statements, so neither was the `rc=$?`'s predecessor and neither matched the source check. `source` is one of the three forms this checker names, so for that syntax a count of zero proved nothing. The scanner now consumes a backslash and the character after it, dropping the pair when that character is a newline, and leaves the single-quoted case alone where a backslash is literal. 2. Adding the control for (1) exposed the worse one. Its header comment contained an apostrophe, `#` only opened a comment at the START of a statement, so that apostrophe read as an opening single quote and swallowed the text up to the next one -- switching off the sql_bare control several functions later. The file then reported three findings instead of four and still exited 0. A checker whose own controls can be disabled by a comment is measuring nothing, so `#` now opens a comment wherever it starts a word. Both are pinned. The continuation control sources a path (`continued-ops.sh`) that nothing else does, because the finding line carries the statement and never the function name -- the first attempt pinned on the function name and passed while detecting nothing. Removing either fix turns the control red. The tree's single finding is unchanged in identity, not merely in count: scripts/remote.sh:1086, which is itself a continuation and was caught by the old scanner for an unrelated reason.

By that point `$SESSION_ID` has been overwritten with the normalized composite `.` — the right token for the exclusivity lock, and a token that exists only inside agmsg. What a terminal knows is the bare sid the CLI published; herdr stores exactly that in `agent_session.value`. So under herdr the claim succeeded and the naming did not. The resolver answered "cannot identify this pane", which reads as a resolution problem and is an identifier mismatch, and the `|| true` on the naming call meant the claim still printed `status=ok`. A hand-started herdr seat took its role and was silently unreachable to peek/poke. `BARE_SID` is already computed two lines up, for the role-session record, and for the same reason. This passes it. The trap is worth naming: in `session-start.sh` the identically named `$SESSION_ID` holds the BARE sid — the hook JSON's `session_id` — and that site was already correct. Same variable name, two different values, and the call looked right at both. `watch.sh:271` does the same lookup and was corrected the same way earlier; this was the site that remained. The control drives `actas-claim.sh` rather than the helper, because the defect is in what the caller passes. The sid goes in already composite, so the normalizer's pid discovery cannot change what is under test, and herdr's list carries the bare one. Two positive controls run first — the claim really happened (`status=ok`), and the fake herdr really was reached (`agent list` in its argv log) — so "no rename" cannot be read as "the resolver never ran". Calibrated: with `$SESSION_ID` restored, the test goes red at the rename, with both positive controls still passing — which is exactly the shape of the defect. test_terminal_registry 63 passed, 0 failed. actas_integration 14 and actas_lock 22 unchanged, measured against this branch's HEAD in alternation (3 runs each, 14/0 in both) after a first sighting of 3 failures turned out to be this machine running several suites at once. --- scripts/actas-claim.sh | 13 ++++++++++- tests/test_terminal_registry.bats | 37 +++++++++++++++++++++++++++++++ 2 files changed, 49 insertions(+), 1 deletion(-) diff --git a/scripts/actas-claim.sh b/scripts/actas-claim.sh index 0661e2fbe..994f160ed 100755 --- a/scripts/actas-claim.sh +++ b/scripts/actas-claim.sh @@ -114,6 +114,17 @@ done <<< "$TEAMS" # claim is what the caller is waiting on, and naming must not be able to fail it # or delay its status line.

The four inline launchers (launch_with_template / launch_{macos,linux,windows}_terminal) are deleted — one implementation, not two. plain still writes no placement record (no addressable pane; the message shapes "via custom terminal template" / "in a new terminal window" are unchanged). record-write failure (co1): the tmux/herdr record writes were `> path 2>/dev/null || true`, so a disk-full/permission failure left a LIVE pane with no record — the only authority peek/poke/despawn --force have — while spawn reported success.

Tests pin a shell-hostile body (backtick, $( ), quotes, $VAR) arriving at the fake driver verbatim by whole-line equality — the vanished-span failure changes the line.

A backtick or $( ) inside it executes there and its span disappears from what arrives -- no error, exit 0, and the member reads a message with a hole in it. That is #507's failure, reintroduced on a surface that has not shipped yet. The templates now teach --body-file: write the text to a file, pass the path. The body never becomes a shell word, so there is no quoting rule to teach and none to get wrong. Adding "remember to quote it" would not have closed this -- the rule is only as good as the reader, and the two people who hit this today both had the rule written down at the time. The positional form still works and is named as fine for a human typing short plain text; the templates just no longer generate one. The block also says that send.sh has no such path yet and that a send body must still be single-quoted, with the issue number (#1032). Two surfaces with different safety and no explanation is how the unsafe one gets picked; the difference is now in front of whoever reads it. Nine templates, one byte-identical block (verified by hashing it in each), and no template still carries the positional form. --body-file is poke.sh's real flag as landed, not an invented one -- the last time these blocks were written the argv was copied from a sibling command and was wrong. --- scripts/drivers/types/antigravity/template.md | 15 +++++++++++++-- scripts/drivers/types/claude-code/template.md | 15 +++++++++++++-- scripts/drivers/types/codex/template.md | 15 +++++++++++++-- scripts/drivers/types/copilot/template.md | 15 +++++++++++++-- scripts/drivers/types/cursor/template.md | 15 +++++++++++++-- scripts/drivers/types/gemini/template.md | 15 +++++++++++++-- scripts/drivers/types/grok-build/template.md | 15 +++++++++++++-- scripts/drivers/types/hermes/template.md | 15 +++++++++++++-- scripts/drivers/types/opencode/template.md | 15 +++++++++++++-- 9 files changed, 117 insertions(+), 18 deletions(-) diff --git a/scripts/drivers/types/antigravity/template.md b/scripts/drivers/types/antigravity/template.md index fb4efef9e..8db2f12a6 100644 --- a/scripts/drivers/types/antigravity/template.md +++ b/scripts/drivers/types/antigravity/template.md @@ -132,8 +132,19 @@ If argument starts with "peek" (e.g. "peek reviewer", "peek alice --lines 80"): If argument starts with "poke" (e.g. "poke reviewer status?"): 1.

(2) herdr terminal_peek captured content through a command substitution, which strips every trailing newline; the following printf '%s\n' then invented exactly one back, so empty content became a lone newline and 0/2+ trailing newlines collapsed to one — a regression of the "visible text verbatim" READ contract. It now captures to a temp file, checks rc, and cats the bytes unmodified; the failure body (herdr writes its error JSON to stdout) goes to stderr, never the caller's content. (3) peek.sh/poke.sh resolved the pane ref with a bare VAR="$(...)". The ref parser fails closed (non-zero) on a corrupt/unknown-scheme ref, so under set -e the shell died AT the assignment and the "did not resolve" die was unreachable. watch.sh's close_own_placement left rec_term/rec_id empty and fell through to a misleading "belongs to someone else" log. Each now guards the assignment (|| VAR="", errexit-safe on bash 3.2) and reaches its own failure contract. Controls added on both backends × both failures, the three verbatim byte-exact cases, and the corrupt-ref guard on all three callers; each new behaviour is mutation-verified.

That was still too broad (co1): a renamed-session drift — agent text, agent_status "running", the session moved under a renamed key like future_session, on a valid pane — meets every type test while HIDING a live target under the renamed key, so it was miscounted as bare and the target reported not-among. B now requires the agent_status VALUE, not merely its type: the measured session-less pane is agent_status = 'done'. A running/idle pane — which must own a session — with no agent_session is an anomaly and stays indeterminate (did-not-answer), never a silent not-among. This errs deliberately narrow: a session-less pane in some other finished-state string falls to did-not-answer rather than being silently ruled out. The front comment ("NO agent_session = bare pane, definitely not the target") is rewritten to match the marker SQL, and the top prose is unified to a single fact boundary: the agent-list shape, the bare-pane fingerprint (agent_status=done), and the pane-id grammar are MEASURED (utildev, live herdr 0.8.0); agent prompt / agent rename argv stay ASSERTED. Controls gain the two future_session cases that hide sess-mine itself and a running-no-session anomaly; the value pin is mutation-verified. --- scripts/drivers/terminals/herdr/ops.sh | 79 +++++++++++++++----------- tests/test_terminal_registry.bats | 21 ++++--- 2 files changed, 60 insertions(+), 40 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 63a5eaa8c..48e007815 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -4,21 +4,26 @@ # Sourced by the terminals registry into the caller's context. terminal_* only, # no set -e/-u. # -# MEASURED (seat 0, 2026-08-29) vs ASSERTED-pending-live-matrix: -# measured: `herdr agent list` is JSON; the pane is resolved from it by the -# session id (inherited HERDR_PANE_ID is NOT trusted; agent_session in the list -# is an OBJECT and the id is at .value); the internal agent-name key is a -# collision-resistant SHA-256 derivation of (team, agent) — see -# _herdr_internal_key for why concatenation/folding has a structural collision; -# the existing spawn/despawn calls (pane split/rename/run, tab create, pane close); -# and `pane read --source ` (seat 0 measured the --source values). -# asserted (exact argv/JSON fields verified only by the live matrix on koit's -# machine, NOT measured here): the `agent list` JSON field names used to -# extract the pane (agent_session / pane_id), `herdr agent prompt`'s argv for -# poke, and `herdr agent rename`'s argv for the internal name key (no existing -# agent-rename call in main to measure against).

This makes the peek/poke asymmetry concrete — peek reads a pane with no live agent, poke needs a running agent, so poke has a "no one to receive" (12) peek does not. - poke.sh added a generic "could not poke ..." line after EVERY failure, including plain's 13 - where the driver had just said "not a dead end, the type template names a native channel". That generic line was the last thing the operator read and cancelled the guidance. The entry now suppresses its summary on 13 (unsupported), letting the driver's reason be the final word; a real 10/12 delivery failure still gets it. The 9 type templates' peek AND poke exit-code notes are updated to the 10/12/13 taxonomy, including the peek/poke asymmetry (a member whose agent has exited can be peeked but not poked). Controls added on both backends x both failures and both entry branches; mutation-verified. --- scripts/drivers/terminals/herdr/ops.sh | 12 ++- scripts/drivers/terminals/tmux/ops.sh | 11 ++- scripts/drivers/types/antigravity/template.md | 4 +- scripts/drivers/types/claude-code/template.md | 4 +- scripts/drivers/types/codex/template.md | 4 +- scripts/drivers/types/copilot/template.md | 4 +- scripts/drivers/types/cursor/template.md | 4 +- scripts/drivers/types/gemini/template.md | 4 +- scripts/drivers/types/grok-build/template.md | 4 +- scripts/drivers/types/hermes/template.md | 4 +- scripts/drivers/types/opencode/template.md | 4 +- scripts/poke.sh | 10 ++- tests/test_peek_poke.bats | 87 +++++++++++++++++++ 13 files changed, 134 insertions(+), 22 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 48e007815..030122b10 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -346,7 +346,17 @@ terminal_peek() { # a tmux send-keys concern, not herdr's.

Startup confirmation (tl hit "spawned" printed while the agent had not started — a startup shell prompt ate the first keystroke of the boot command). Every placement line now says "launched '' in " — a placement fact, never "spawned". Whether the agent actually started is a separate line: status=ready (the watcher attached — a positive observation) is the only proof of startup; a type with no readiness handshake (monitor=no) prints status=launched-unconfirmed note=no-readiness-handshake with an explanation instead of letting the placement line stand as success. An explicit --no-wait stays terse and never acquires the unconfirmed line (it is the user opting out, not a type that cannot confirm). Atomic placement record. spawn.sh _record_placement and agmsg_terminal_name_self wrote the record with a raw `>`, which truncates at open — so a write that then fails (ENOSPC / permission), including the SessionStart/actas re-name of a pane that already had a correct record, destroyed the authority peek/poke/despawn depend on BEFORE it could report the failure. Both now route through agmsg_write_atomic (temp + rename — the helper six other scripts already use, not a seventh copy), so a failed write leaves the old record whole; status=spawned-but- unrecorded is reported only when the write genuinely could not land. The two were the only raw `>` into a placement record (the rest under run/ are ephemeral pidfiles). Controls: launched-unconfirmed vs status=ready vs terse --no-wait; the record-write failure reported without truncating; the atomic write preserving an existing correct record on failure. Each mutation-verified; enforced-assertions and errexit checkers at baseline. --- scripts/lib/terminal-registry.sh | 14 ++++++- scripts/spawn.sh | 43 +++++++++++++++++----- tests/test_spawn.bats | 61 ++++++++++++++++++++++++++++--- tests/test_terminal_registry.bats | 25 +++++++++++++ 4 files changed, 127 insertions(+), 16 deletions(-) diff --git a/scripts/lib/terminal-registry.sh b/scripts/lib/terminal-registry.sh index 618db48cb..928144b4d 100644 --- a/scripts/lib/terminal-registry.sh +++ b/scripts/lib/terminal-registry.sh @@ -45,6 +45,16 @@ if ! declare -F agmsg_driver_bases >/dev/null 2>&1; then [ -n "$_AGMSG_TERMINAL_LIB_DIR" ] && .

The 'done' was a VALUE at a moment, not a property of a bare pane — the same trap as reading agent as a value instead of a kind. A key-NAME allowlist has the same flaw: name/display_agent appear and vanish on a live pane (naming is this driver's own job), so a named pane would fall out of the allowlist intermittently. B now recognizes a bare pane by STRUCTURE (co1/tl 2026-09-04), from four conditions: (a) the agent_session key is absent, (b) a valid pane_id, (c) the fixed identity anchor (agent, terminal_id, tab_id, workspace_id — measured always-present) is present, and (d) NO field is object- or array-valued. (d) is what closes co1's renamed-session drift for ANY shape: a session hidden under a renamed key — future_session:{…}, future_sessions:[…], session_ids:[…] — is a structured value and fails (d), so the entry is indeterminate and the target it hides is never reported not-among. A scalar extension (name, display_agent) passes, so a named bare pane still reaches not-among (that state was unobserved as of 2026-09-04; its control is defensive). Also fixes a real correlation bug the structural check exposed: the entries table is now aliased (e) so the correlated json_each(e.value) binds per row — a bare json_each(value) returns the same answer for every row. Controls: working/idle/done + named + unknown-scalar bare panes all reach not-among; every object/array hiding shape and a bare {} stay did-not-answer. The value-pin regression, (c), and (d) are each mutation-verified; checkers at baseline. --- scripts/drivers/terminals/herdr/ops.sh | 109 +++++++++++++++---------- tests/test_terminal_registry.bats | 73 +++++++++++------ 2 files changed, 115 insertions(+), 67 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 030122b10..07595c9af 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -10,9 +10,15 @@ # `agent list`, with positive controls): # - `herdr agent list` is JSON; agent_session in the list is an OBJECT and the # session id is at .value (inherited HERDR_PANE_ID is NOT trusted). -# - a session-less pane has the agent_session KEY ABSENT entirely, with agent -# present (the kind) and agent_status exactly "done" — this is the bare-pane -# fingerprint B relies on; no live-list entry carries a JSON-null agent_session. +# - a session-less pane has the agent_session KEY ABSENT entirely; no live-list +# entry carries a JSON-null agent_session.

The signal is structural and environment- independent (co1/tl 2026-09-04): herdr pane process-info reports shell_pid and foreground_process_group_id, and the shell is at its prompt iff the foreground process group is the shell itself. No prompt string is matched (zsh/bash/Windows alike) and no point-in-time value is baked in — the trap that bit agent_status='done' and the key allowlist. The obvious herdr calls do not fit (all measured 2026-09-04, recorded in the code so nobody re-hunts): agent start takes only a --kind enum, not our boot script; agent wait waits for an agent state and a bare shell is not in agent list; agent list has no shell-readiness field. process-info is the one. Three outcomes, kept distinct like peek's 10/12/13: - READY: both ids present and canonical positive integers AND equal -> type. - NOT READY: both validated, unequal -> do not type; bounded wait, then close the pane and fail with the reason (exit 3). - UNKNOWN: command failed / field missing / not a positive integer -> type anyway, but flag it (exit 4). "" == "" / null == null / same-malformed are UNKNOWN, never READY: equality is read only after positive validation (co1). A nonexistent and a malformed pane give the same error, so both are UNKNOWN, not split. spawn.sh maps the arms: arm 4 sets SPAWN_READINESS_UNVERIFIED, which prints a BEFORE-typing warning worded apart from the AFTER-typing launched-unconfirmed (utildev) so an operator can tell which check was blind. Per co1's priority the warning does not decide the startup verdict — a watcher that then attaches still makes the status ready; a monitor=no type still reports launched-unconfirmed on its own. NECESSARY, NOT SUFFICIENT, and said so in the code: a shell reading its OWN prompt (no child) returns equal, so a first keystroke can still be lost (unmeasured 2026-09-04); that residual is caught after typing, not here. Controls: not-ready fails without typing and closes the pane; unknown types and warns and records; null==null is unknown not ready; ready is silent; plain never runs the gate; the two unconfirmed reasons read apart. Each arm and the positive validation are mutation-verified; checkers at baseline. --- scripts/drivers/terminals/herdr/ops.sh | 68 ++++++++++++++++++++++ scripts/spawn.sh | 29 +++++++++- tests/test_spawn.bats | 79 ++++++++++++++++++++++++++ tests/test_terminal_registry.bats | 5 ++ 4 files changed, 178 insertions(+), 3 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index 07595c9af..c2c232787 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -280,6 +280,51 @@ _herdr_new_pane_id() { return 1 } +# requirement 1 (herdr pre-input readiness).

A second pane joining an already-held identity must not take the placement over. That property went in, and nothing guarded it. Measured rather than reasoned: adding `record` to join.sh's call — which restores exactly the defect it was added to fix — leaves `test_terminal_registry` and `test_actas_integration` with zero failures. The helper's safe default is covered; whether the caller takes that default is not, and those are different claims. So the control is driven through `join.sh`, not through the helper. A record for pane A is in place, the join runs from pane B, and the assertion is that A's record is UNCHANGED — not that "join did not break anything", which a version that emptied the file would also pass. A positive control goes first: the pane really was named. Without it, a join that skipped the naming step altogether leaves the record alone too, and this test would read that as the property holding. Calibrated in both directions, with the mutation checked before its result was trusted: the `record` argument is confirmed present in the mutated file, the control then fails at `[ "$(cat "$rec")" = "$before" ]`, and restoring the file turns it green. test_terminal_registry 69 passed, 0 failed. check-enforced-assertions 635 and check-errexit-status-reads 1, both at their baselines. --- tests/test_terminal_registry.bats | 41 +++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/tests/test_terminal_registry.bats b/tests/test_terminal_registry.bats index f005da24e..a58671e4e 100644 --- a/tests/test_terminal_registry.bats +++ b/tests/test_terminal_registry.bats @@ -1207,3 +1207,44 @@ M [ -f "$rec" ] grep -Fq 'herdr:wC:p4' "$rec" } + +# --- join names a pane; it does not take the seat ----------------------------- +# +# The 6th argument's default is "do not write the record", and join is the caller +# that relies on it: the same identity can be joined from a second session while a +# first one holds it through actas, and the record is what peek/poke resolve a +# member's pane through.

Now `ready_rc=0; classifier || ready_rc=$?`. (The spawn.sh tests call terminal_spawn inside `$(...)`, which masks errexit; a new control drives it from a NON-conditional set -e caller, and the fix is mutation-verified.) (2) The wait bound was `${AGMSG_HERDR_INPUT_READY_TRIES:-50}` — an undeclared, unvalidated env surface. An empty / 0 / non-numeric value would make the loop never run, silently skipping the observation (UNKNOWN → boot), the very thing the gate prevents. It is now a fixed 50 (~5s) with no knob. (3) The pid fields were read with json_extract only, so a JSON string "123" extracted as 123 and passed the digit check — a numeric string is not a validated pid. The classifier now requires json_type = 'integer' in the same payload before the value; a numeric-string equal/unequal is UNKNOWN. (4) The prose over-claimed. (d‴) rejects object/array-valued fields, so it catches a session moved to a renamed OBJECT or ARRAY key (inner shape irrelevant) — the measured agent_session is an object. It does NOT catch a session flattened to a SCALAR (a renamed key whose value is the bare target string): that is the deliberate cost of allowing unknown scalar extensions (name/display_agent are real), and it is now named as a residual in the code and the PR body, not implied closed. Controls: the non-conditional set -e reach; numeric-string → UNKNOWN; the fixed bound still fails a never-ready pane. Checkers at baseline. (The errexit checker's blind spot for a generic bare command → next-line `$?`, and the join-record load-bearing control, are tracked separately.) --- scripts/drivers/terminals/herdr/ops.sh | 52 +++++++++++++++++++------- tests/test_spawn.bats | 14 ++++++- tests/test_terminal_registry.bats | 16 ++++++++ 3 files changed, 67 insertions(+), 15 deletions(-) diff --git a/scripts/drivers/terminals/herdr/ops.sh b/scripts/drivers/terminals/herdr/ops.sh index c2c232787..a6635835b 100644 --- a/scripts/drivers/terminals/herdr/ops.sh +++ b/scripts/drivers/terminals/herdr/ops.sh @@ -16,9 +16,11 @@ # changes; name/display_agent come and go): the agent_session key is absent, the # pane_id is valid, the fixed identity anchor (agent/terminal_id/tab_id/ # workspace_id, measured always-present, 0 variance over 11 panes, 2026-09-04) -# is present, and NO field is object/array-valued (so a session hidden under a -# renamed key cannot pass). display_agent was a string in one 2026-09-04 agent -# list; a NAMED bare pane was not observed by 2026-09-04 (its control is defensive). +# is present, and NO field is object/array-valued (so a session moved to a renamed +# OBJECT/ARRAY key cannot pass; a session FLATTENED to a scalar is an unidentifiable +# residual — the cost of allowing unknown scalar extensions, named at the det CTE). +# display_agent was a string in one 2026-09-04 agent list; a NAMED bare pane was not +# observed by 2026-09-04 (its control is defensive). # - the pane-id grammar (w1:p4, w1:pB, w5:p3, w1:pC). # - `pane read --source ` (seat 0 measured the --source values). # - the internal agent-name key is a collision-resistant SHA-256 derivation of @@ -163,10 +165,20 @@ _herdr_pane_for_session() { -- (b) a valid pane_id (grammar above); -- (c) the fixed identity anchor is present (anchor_ok); -- (d‴) no field is object- or array-valued (struct_free). - -- (d‴) is what closes co1's renamed-session drift for ANY shape: a session - -- hidden under a renamed key (future_session:{…}, future_sessions:[…], - -- session_ids:[…]) is a structured value, so it fails struct_free -> the - -- entry is indeterminate and the target it hides is NOT reported not-among. + -- SCOPE of (d‴), stated exactly (co1): it catches a session moved to a + -- renamed OBJECT or ARRAY key -- future_session:{…}, future_sessions:[…], + -- session_ids:[…], inner shape irrelevant -- because the MEASURED agent_session + -- is an object, so a structured value where none belongs fails struct_free and + -- the target it hides is NOT reported not-among.

That list enumerates SYNTAX the scanner may mis-split — heredocs, backticks, arithmetic, `case` separators. It does not enumerate the SHAPES that produce `$?` in the first place, and that is the axis that failed: a bare command or function call followed by `rc=$?` is not looked at at all, because the predecessor is only examined when it is an assignment with a command substitution, or a `source`. Review found such a site in this branch while the checker stayed green. Under `set -e` that shape exits the shell before the status can be classified, which in that case killed a gate whose entire purpose was to classify three outcomes. The splitter is not at fault — fed that site it returns the two statements correctly. The predicate is narrow. Widening it, and counting what the tree then shows, is #1034 and deliberately not done here: the count is unknown, an attempt to measure it failed its own positive control, and a change of unknown size does not belong immediately before a freeze. So this records the gap rather than closing it, and says which axis was missing so the next reader does not take the syntax list for the whole story.

The `%HELD` / `/proj/OLD` greps stay, now as documentation of what the file says rather than as the check. The claim was the part that was wrong, not the design: the test name and the comment said the record was unchanged while the assertion could only see part of it. Narrowed the assertion to match the claim rather than the other way round.
