fix(bin): close decisions with mid-note keys

[EvanAgee]

Intent

Fix Firstmate's decision tracking so a needs-decision: or blocked: status line with one canonical [key=] token in the middle of its note opens under that key and can be closed by bin/fm-send.sh --resolve-key. Reproduce the exact pto-export-window-ui shape, where "needs-decision: fix-review found 2 new ask-user findings [key=169-noun-and-grade-labels]: ..." previously opened an unkeyed ghost, then assert a keyed answer succeeds and the decision closes. Preserve existing well-formed key positions and unkeyed behavior. Do not rewrite state/*.status history. Rebuild persisted decision-fold cursors so already-stuck records in existing append-only logs use the corrected grammar. Choose the forgiving parser approach because workers and trusted scripts append directly to status files, so there is no single write path that can reject malformed lines reliably. Keep multiple valid interior canonical key tokens ambiguous instead of choosing one arbitrarily. Ignore malformed key lookalikes when one valid canonical interior key remains, so a malformed lookalike cannot hide the closable key. Explain the chosen parser approach and the rejected write-time validation approach in the PR body.

What Changed

• Recognize one canonical [key=<slug>] token inside needs-decision: and blocked: notes, including the pto-export-window-ui case, so fm-send.sh --resolve-key can close the decision.
• Preserve existing key positions and keyless behavior. Multiple valid interior keys remain ambiguous, while malformed lookalikes cannot hide one valid key. Rebuild saved decision-fold cursors from append-only status history under the corrected grammar.
• Use forgiving read-time parsing because workers and trusted scripts write status lines through several paths. Write-time validation was rejected because no single write path can enforce it reliably.

Risk Assessment

🚨 High: Captain, source risk is high because malformed input can still hide a valid closable key or create an unintended default decision.

Testing

No prior baseline commands were supplied. Targeted parser, send, and watcher tests passed. Manual CLI evidence reproduced the old unkeyed ghost, showed the target opening and closing the named decision, and confirmed old cursor rebuilding without status-history rewrites. This shell-only change has no rendered UI to capture.

Evidence: Decision key end-to-end evidence

Source: Decision key end-to-end evidence

Shows the exact decision opening under key 169-noun-and-grade-labels, a successful fm-send.sh --resolve-key, the appended resolution, no remaining open decisions, and a v5 cursor rebuilding to v9 without changing status history.

Scenario 1: exact mid-note key, answered through the real fm-send executable

$ FM_STATE_OVERRIDE=<fixture>/state bin/fm-wake-drain.sh
OPEN DECISIONS (still open, folded from the durable status logs - not just the latest line):
pto-export-window-ui [key=169-noun-and-grade-labels] needs-decision: fix-review found 2 new ask-user findings: choose the noun and grade labels
OPEN DECISIONS: close one by answering it: bin/fm-send.sh <task> --resolve-key <key> '<answer>'

$ bin/fm-send.sh pto-export-window-ui --resolve-key 169-noun-and-grade-labels "use the revised labels"
exit: 0
transport received: use the revised labels

append-only status log after the answer:
     1	needs-decision: fix-review found 2 new ask-user findings [key=169-noun-and-grade-labels]: choose the noun and grade labels
     2	resolved [key=169-noun-and-grade-labels]: answered: use the revised labels

open decisions after the answer:
(none)

Scenario 2: old persisted cursor rebuilds without rewriting status history

planted cursor version: version=5
folded open decision after rebuild:
169-noun-and-grade-labels	needs-decision	fix-review found 2 new ask-user findings: choose the noun and grade labels
rebuilt cursor version: version=9
status history SHA-256 before: 3ec8b13292aac8c77c71e1fce5b5e15c5176290b0be3654acb115cf8a66cbedd
status history SHA-256 after:  3ec8b13292aac8c77c71e1fce5b5e15c5176290b0be3654acb115cf8a66cbedd
status history unchanged: yes

Evidence: Regression before and after

The base commit folds the exact fixture under default; the target commit folds it under 169-noun-and-grade-labels.

Exact regression fixture folded by the base commit:

⚠️ **Review** - 2 errors

• 🚨 bin/fm-classify-lib.sh:335 - The requirement says “Preserve existing well-formed key positions and unkeyed behavior,” but this new interior-key branch runs for every status verb. working: documenting the [key=foo] syntax now opens activity foo with note documenting the syntax; a later unkeyed done: closes default and leaves foo falsely open. Limit middle-key recognition and stripping to decision openers at the decision-fold boundary.
• 🚨 bin/fm-classify-lib.sh:367 - The requirement says “Ignore malformed key lookalikes when one valid canonical interior key remains,” but an earlier positional candidate still stops this fallback before validation. For needs-decision: [key=bad key] review found [key=review-labels]: choose, the head parser returns bad key, validation fails, and the valid middle key is never considered, so --resolve-key review-labels still refuses. Validate each candidate before applying precedence, while preserving rejection when every candidate is malformed.

🔧 Fix: Fix decision key scope and candidate validation
2 issues (1 error, 1 warning) still open:

• 🚨 bin/fm-classify-lib.sh:295 - The intent requires “Keep multiple valid interior canonical key tokens ambiguous instead of choosing one arbitrarily,” but punctuation makes this check ignore an otherwise complete token. needs-decision: should docs mention [key=prose] or [key=example]? counts only prose and opens that key instead of default. The fix round changed this exact fixture to remove the question mark. Treat punctuation as a valid token boundary so both keys reach the ambiguity check.
• ⚠️ bin/fm-classify-lib.sh:379 - The scanner returns only the selected slug, so note cleanup removes the first matching text even when the scanner rejected that occurrence. For needs-decision: compare x[key=route] prose, then choose [key=route]: A or B, key selection correctly ignores the embedded lookalike, but cleanup deletes that lookalike and leaves the real key token in the displayed note. Return the accepted token’s location or the cleaned note from the scanner, then remove that exact occurrence.

🔧 Fix: Handle punctuated keys and exact token cleanup
2 errors still open:

• 🚨 bin/fm-classify-lib.sh:291 - The required rule says, “Ignore malformed key lookalikes when one valid canonical interior key remains,” but an unclosed lookalike still consumes the valid token. needs-decision: review [key=bad before [key=review-labels]: choose parses through the valid token’s closing bracket as one malformed slug, skips the opener, and leaves --resolve-key review-labels refusing. Make _fm_key_raw_anywhere recover when another [key= begins before the current candidate closes.
• 🚨 bin/fm-classify-lib.sh:305 - The approved rule says to “preserve rejection when all stated candidates are malformed,” but [key=] never sets the scanner’s invalid flag. needs-decision: review [key=]: choose therefore opens default instead of being skipped. Track complete token presence separately from nonempty slug text so an empty token is rejected unless another valid candidate remains.

Banked findings

These parser refinements are intentionally deferred:

• An unclosed malformed [key= token before a valid key can still consume the valid token, so --resolve-key may refuse that edge case.
• An empty [key=] token can still fall back to the unkeyed default decision instead of being rejected.

📝 Walkthrough

Walkthrough

The classifier now accepts one unique canonical [key=...] token inside a decision note. It removes the token during note normalization, rejects ambiguous tokens, increments the fold version, and adds classification, cursor rebuild, and resolution coverage.

Changes

Decision-key handling

Layer / File(s)	Summary
Interior key parsing and fold invalidation bin/fm-classify-lib.sh	The grammar and parser support one unique interior canonical key. Note normalization removes the token. The fold version increases from 5 to 6.
Classification and resolution coverage tests/fm-classify-decision-key.test.sh, tests/fm-send-resolve-key.test.sh	Tests cover unique and ambiguous mid-note keys, stale cursor rebuilds, and resolving a mid-sentence decision.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to b3f80

The change improves keyed decision recovery and resolution, but a malformed key-like token can still prevent a valid key from being recognized, and a concurrent same-key update could be hidden during resolution. The PR is mergeable with owner awareness and follow-up for these bounded edge cases.
