Addresses a Gosec G204 (Command Injection) warning where provider command strings were passed directly into `sh -c` and `cmd /C`. Since these commands originate from the user's trusted local config and explicitly require shell features (like pipes and variable expansions) to function, removing the shell invocation introduces a breaking change. This adds a documented `#nosec` annotation to suppress the false positive instead of degrading functionality. Co-authored-by: euxaristia <25621994+euxaristia@users.noreply.github.com>

In `@internal/agent/compaction_preserve.go`:
- Around line 623-637: Update mergeBoundedComparable so repeated values are
removed from their prior position and appended at each newest occurrence,
matching mergeTaskFailures and mergeRecentEdits. Preserve first-seen order for
unique values and apply the existing tail limit after deduplication so recently
observed evidence is retained.
In `@internal/agent/compaction.go`:
- Around line 268-272: Replace the raw `messages` fallback in the compaction
flow around `projectCompactionInput` with a bounded input that uses the same
projection limits and metadata semantics. Ensure empty projections cannot pass
unbounded tool results or clipped assistant content to the summarizer, and keep
`ProjectedChars` and `Truncated` consistent with the bounded fallback.
In `@internal/agent/context_measurement_test.go`:
- Around line 35-37: Update the breakdown assertion in the relevant context
measurement test to verify that breakdown.Blocks contains the expected system,
tools, and conversation category identifiers, including their required order or
set semantics, rather than only checking the count. Preserve the existing
failure context and use the category symbols defined by the test contract.
In `@internal/peermsg/private_dir_unix.go`:
- Around line 21-60: Update the descriptor cleanup in the directory walk around
parentFD: replace the direct deferred unix.Close call with a closure that closes
the current parentFD value at return, while retaining the explicit close before
assigning nextFD. This must prevent closing the root descriptor twice and ensure
the final/current descriptor is closed on success and every error return.
In `@internal/peermsg/service.go`:
- Around line 649-651: Prevent duplicate held-message IDs in the receive path
around the response validation and held-message insertion: before parking a
valid frame, reject it with DeliveryRefused when service.held already contains
frame.ID, or consistently namespace the key with the sender identity. Ensure
heldOrder uses the same unique key and eviction accounting so collisions cannot
overwrite approvals or grow the order list without bound.
In `@internal/tools/peer_sessions.go`:
- Around line 104-118: Sanitize and bound peer.Name and peer.Cwd in the list
formatting flow before writing them to output. Reuse the existing
peerDisplayName behavior for the name where applicable, and strip control
characters plus truncate both fields to prevent forged rows and oversized output

- Around line 694-704: Update renderPeerMessageRow to sanitize the

Dedupe keeps the oldest position, so the tail cap can drop just-refreshed evidence.
mergeBoundedComparable keeps the first occurrence of a repeated value and ignores the later one. mergeTaskFailures does the opposite: it moves a repeated key to the newest position. mergeRecentEdits also moves a re-edited path to the tail, and the comment at Lines 525-528 explains why.
With that inconsistency, once ChangedFiles, Approvals, or Artifacts reach their cap, an item observed again in the latest turn stays at its old position and the tail cap can evict it. An item untouched for many turns survives instead. The preserved state then loses the most relevant evidence.
Move a repeated value to the newest position, matching the other two mergers.

The empty-projection fallback sends the raw, unbounded middle to the summarizer.
projectCompactionInput returns an empty projection when it produces no sections and finds no previous summary. That happens when the middle holds only skipped material, for example successful non-ask_user tool results with no ChangedFiles, plus assistant turns whose content clips to empty. Those tool results can still carry very large bodies, and pruneSupersededReadResults does not always remove them.
In that case summaryInput = messages bypasses every bound the projection enforces. The summarizer then receives the full raw slice, which can exceed the context window and reintroduce reconstructible tool output into the prompt. ProjectedChars also reports the raw size while Truncated stays false, so the metadata hides it.
Bound the fallback instead of using the raw slice.

Fix the double close and file-descriptor leak in the directory walk.
Arguments of a deferred call are evaluated when defer executes. Line 25 therefore always closes the root descriptor, not the current one.
Two defects follow:
- The root descriptor is closed twice: once at line 58 in the first iteration, and again by the deferred call at return. A double close can close an unrelated descriptor that another goroutine opened in the meantime.
- The descriptor of the last component (and of the current component on every error return at lines 34, 39, 42, and 46) is never closed. Each call leaks one descriptor.
Close the current descriptor through a closure instead.
🐛 Proposed fix for descriptor handling
defer unix.Close(parentFD)
+ // Closes whichever descriptor parentFD currently holds, including on error returns.Replace line 25 and line 58 as follows:
- defer unix.Close(parentFD)
+ defer func() { unix.Close(parentFD) }()
for index, component := range components {
@@
- unix.Close(parentFD)
- parentFD = nextFD
+ unix.Close(parentFD)
+ parentFD = nextFDWith the closure in place, line 58 keeps closing the previous descriptor and the deferred call closes the final one.

Reject or namespace duplicate message IDs before parking a held message.
frame.ID is chosen by the sender. The receiver only checks that it is not empty (line 650). service.held is keyed by that raw ID, so two senders can pick the same ID, and one sender can reuse an ID.
Two consequences follow:
- Line 726 overwrites the earlier held message. The first sender never receives a terminal receipt, and the local approval for that message disappears from the map while the sender keeps the entry in
outstandinguntil the TTL expires. - Line 727 always appends to
heldOrder, but the eviction check at line 722 useslen(service.held). Repeated collisions therefore growheldOrderwithout a bound while the map size stays constant.
Key held messages by sender endpoint plus ID, or refuse a frame whose ID already exists.
🐛 Proposed fix: refuse colliding IDs
if status == DeliveryHeld {
var evicted InboundMessage
var evictionHandler HeldEvictionHandler

Bound and sanitize peer.Name and peer.Cwd before formatting the list.
Name and Cwd come from another session's published record. The TUI bounds the display name with peerDisplayName (48 runes), but this tool writes both fields raw. A name that contains \n- Someone [deadbeef] forges an extra row in the model-visible list, and a long name inflates the tool output. Strip control characters and truncate both fields.

Gitlawb#1016) * fix(sessions): carry an interrupted turn's work into the resume prompt A turn that read six files and then died on a provider error left this behind for the next turn: - #1 message: add retries to the http client - #6 error: provider error: upstream timeout Nothing named the files, so the next turn re-read them from scratch (Gitlawb#913). The work was never lost from the session: tool calls and results are recorded as they happen, and the error path carries them out with everything else. promptContextEvents then dropped both types on the way into the prompt, so the record existed and nothing read it. Filtering them was deliberate (Gitlawb#460) and is right for work an answer already describes: forty read_file results add length and no information next to the assistant message explaining them. It is wrong only for work with no answer after it, and that is exactly what an interruption leaves. A turn that ends normally was survivable for that reason, which is why this went unnoticed: the answer was doing the remembering. So the events after the last assistant message come along and the rest stays filtered. The tail gets its own allowance rather than sharing the conversation budget, so a tool-heavy interrupted turn still cannot push an earlier message out of the context. That is the property Gitlawb#460 added the filter for and it is asserted directly. This changes a tested contract. TestFormatExecPromptKeepsConversationMessagesWhenNoisyEventsFollow asserted that tool results are omitted, and its fixture is an interrupted turn: 43 results after an assistant answer with nothing speaking for them. That is the Gitlawb#913 shape, so no rule satisfies both and the contract had to move. The test keeps the guarantee it was written for, that conversation survives a noisy turn, and a counterpart now pins the other half: work an answer already covers is still filtered. Not fixed here, and worth saying plainly: this carries what was DONE, not what was READ. Zero has no conversation-history parameter at all, agent.Run seeds from the system prompt and the user prompt every time, so file contents cannot survive a turn boundary today. The next turn learns it already read a path and can decide, rather than starting blind. * fix(sessions): carry the tool outcome, not the tool output The tail was carrying whole tool-result events, so up to 500 bytes of raw tool output rode into a later turn prompt. Nothing redacts on the way in, and the prompt renderer truncates rather than filters, so the only thing standing between a file read and a later prompt was a length limit. It bought almost nothing. The tail exists so a resumed turn knows what the interrupted one did, and the CALL already says that: the tool name and its arguments, which is the path for a read. The result body is the one part of the pair that can carry file contents. The status is kept rather than dropping the result entirely. A bare call reads as work that succeeded, so a failed read would come back as a file the next turn believes it already has. Raised by CodeRabbit on the PR, and right. * test(sessions): scope the outcome assertion to the tool_result lines The status check searched the whole prompt for "error", which the provider error message in the same fixture also contains. Blanking the status out left the test passing, so it was asserting the presence of an unrelated line. Scoped to the tool_result lines, it fails on that mutation naming the outcome it lost. * test(sessions): pin the whole of every tool line, not a search for one string Two assertions here were weaker than what they claimed. Searching the prompt for the fixture's whole secret only rejects that exact string, so a change that carried a truncated or partly redacted prefix of the output into the prompt would have passed. And asking whether "ok" and "error" each appear somewhere among the result lines passes just as well with the two statuses swapped, or both hung off the wrong call. Both tool calls and both results are now pinned outright, which says what the trim actually promises: nothing but the tool name and the outcome survives a result, and the line order pairs each outcome with its own call. Compared as a set of fields per line rather than as a string, because the renderer walks the payload map and Go randomizes that order, so the same events come out in a different field order on every run. Reported by CodeRabbit on this PR. * fix(sessions): keep a tool call's identity and drop its payload in resume context toolResultOutcome strips a result down to name and status, and calls were left verbatim, so an interrupted write_file put its content into the next turn's prompt while the matching result body did not. Same secret, one door left open. Admitting calls is the Gitlawb#913 fix and has to stay: a resumed turn knowing which file was read is the whole point. What had to change is the symmetry. toolCallIdentity is the call-side half of toolResultOutcome. It decodes the arguments, keeps the fields that say what a call was about, and drops the ones that carry what it was about to write, run or search for. Paths, directories, urls, names, patterns and a read window survive; write_file's content, edit_file's old and new strings, apply_patch's hunks and a shell command line do not. An allow-list rather than a deny-list, so an argument this file has never seen is dropped rather than replayed. A new tool with a new body field then shows up as a missing path in a resume prompt, which is visible, instead of a new leak, which is not. Keyed by argument name rather than tool name, so an MCP tool whose argument is a url keeps it without being enumerated. Arguments that do not decode as an object are removed outright: text that could not be read is text that cannot be checked. The tail budget gets a comment rather than a change. Tail slots exist only when the conversation uses fewer than the 80-event cap, so a session already at the cap carries no interrupted tool work, which is what every session did before tool events were admitted and what the Gitlawb#460 cap is there to hold. Reserving a minimum tail by trimming conversation further is a product decision, and it is not this one. Reported by jatmn. * fix(sessions): scrub credentials out of retained tool-call values An allow-listed key is not a safe value. web_fetch accepts a credential in the query string and redacts the URL it reports back, so an interrupted fetch had its token dropped from the result and kept verbatim in the call, and this projection then carried it into the next resume or fork prompt. Retained string values now go through the same redaction web_fetch uses on its own returned URL: host, path and ordinary query survive, the token does not, and non-string values are untouched. * fix(sessions): project a tool call's top-level fields instead of patching one toolResultOutcome builds its output from the fields it keeps, so a field it has never heard of cannot reach a prompt through it. The call side edited arguments in place and returned every sibling key, and returned the payload untouched when there were no arguments at all, so a producer recording one more top-level field would put it into the next turn. Both halves now name what survives and drop the rest. * fix(sessions): name the value shapes a projected argument may keep, and scope the ambiguous aliases Two halves of the same gap: the projection decided which KEYS survive and said nothing about the values under them or about which tool gave them meaning. Values. Strings were scrubbed and everything else passed through, which reads as "a number is nothing to scrub" and is true of a number and not of an object. MCP schemas allow object and array properties, so {"query":{"api_key":"...","content":"private body"}} arrived under a permitted key and carried a whole payload into the next prompt. Redacting a serialized object would not have helped, since ordinary private text has no credential shape to match. The retained shapes are named now: a scrubbed string, and the scalars a read window is made of. A container is dropped and the call keeps its name and id, so a resumed turn still knows which tool ran. Meaning. grep accepts "search" for its pattern and edit_file accepts the same word for the text being replaced, so admitting it globally would have replayed file contents. It is scoped to grep, and the rule is kept as a test: an argument name any mutating tool accepts for body content belongs in the per-tool table or nowhere. The unambiguous supported forms are added to the shared table: glob's match, and read_file's start_line, end_line, max_lines, byte_offset and byte_limit. Driven through the store on both resume and fork, including a call the tool would have rejected, since the agent records OnToolCall before execution. The persisted events are asserted unchanged: this is a view for the prompt, not an edit to the record. * test(sessions): assert the window key with its value, not the number alone strings.Contains(out, "40") finds it inside "4096", so the start_line assertion passed whether or not start_line survived the projection, which is the opposite of what it claimed. The rendered arguments carry the pairs, so the assertions name them.

🎯 What: The Gosec G204 vulnerability indicating potential command injection by running user-supplied variables directly via a system shell.
⚠️ Risk: Left unfixed, automated security scanners raise this as a medium-severity issue. However, because the input is drawn directly from the user's local configuration file, it is considered trusted.
🛡️ Solution: Rather than removing the system shell (which would break critical shell-specific features like pipes and redirects that users rely on for provider configurations), this PR formally acknowledges and suppresses the false positive by adding an inline
/* #nosec G204 */annotation with a clear justification.PR created automatically by Jules for task 11803407121707453049 started by @euxaristia
