Night Market Failure Archaeology

This is a reference document, not a runbook. It records every major investigation, dead end, rejected fix, and revert in this repo as symptom, root cause, evidence, status, and lesson, so nobody re-fights a settled battle. For triage of a failure happening right now, use night-market-debugging-playbook. Come here when a proposed change smells like something the repo already tried and rejected.

Jargon used below:

"py39 hooks": hook scripts run under the host system Python (3.9 floor), while the rest of the repo requires Python 3.12. Enforced by .github/workflows/python39-compat.yml.
"unbloat": the conserve plugin's dead-code deletion campaign.
"Stop hook": a Claude Code hook that runs when a session turn ends.
"settled": the fight is over. Re-opening it requires new evidence and a note in the collective memory, not a hunch.

How to use this chronicle

Before implementing, scan the battle titles and the recurring-class table for anything resembling your plan.
If a battle matches, read its lesson. Follow it, or write down why this time is different before overriding it.
Verify any hash you rely on: git log --format='%h %s' -1 <hash>.
When your own battle settles, add an entry (format at the bottom).

Settled battles

SB1: tasks_manager cross-plugin DRY consolidation (reverted)

Symptom: three near-identical tasks_manager.py copies in attune, sanctum, and spec-kit looked like textbook duplication.
Root cause of the failure: consolidating them into a root scripts/tasks_manager.py (1,169 lines deleted across 6 files) broke plugin self-containment. Plugins are independent deployables that run from a Claude Code cache directory, so they cannot import from the repo root.
Evidence: 054e2679 (consolidate, 2026-01-23), 29961cd2 (revert, same day), d89a55c7 (differentiated per-plugin copies). All three copies exist today under plugins/<p>/scripts/tasks_manager.py. docs/dependency-audit.md tracks cross-plugin deps and fallbacks.
Status: settled. Per-plugin copies are intentional.
Lesson: DRY across plugin boundaries is an anti-pattern here. Do not "helpfully" re-consolidate duplicated plugin scripts.

SB2: LSP proxy (speculative infrastructure, killed)

Symptom: scripts/lsp-proxy.py added for "graceful server fallback" with no consumer demanding it.
Root cause: speculative abstraction built ahead of need.
Evidence: 2fcb256d (add), killed in PR #193 review, bc318947 (revert, 2026-02-11, restores .cclsp.json).
Status: settled. Do not re-add without a concrete consumer.
Lesson: infrastructure without a present consumer dies in review. See also .claude/rules/shared-utility-consumer-rule.md.

SB3: Tier-3 unbloat over-deletion (2026-03-28, the big one)

Symptom: unbloat deleted 182 files (66K lines) using only the Python import graph to decide what was dead.
Root cause: skills and commands reference scripts from markdown, not Python imports. 28 actively referenced scripts plus 18 companion test files were classified dead and deleted.
Evidence: a3f11323 (the deletion), 3f280334 (restore the 28 scripts and 18 tests), b5f08bf7 (CI repair: dead docs workflow, missing capabilities entries), d6c128f5 and 01a13e70 (further repair and governance follow-ups). Recovery point was branch backup/unbloat-20260328.
Status: settled, with the highest single blast radius on record.
Lesson: any deletion campaign must scan markdown references (skills, commands, agents), never imports alone. Always take a backup/unbloat-<date> branch first.

SB4: bulk lint ignores (reverted)

Symptom: global ruff ignores made parseltongue lint pass while hiding 73 real violations.
Root cause: silencing the gate instead of fixing the findings.
Evidence: 06b9b1db (2026-03-10) reverts the bulk ignores and fixes all 73 at source. The commit body cites issue #296 as the anti-bulk-ignore policy anchor.
Status: settled. Constitution rule 6 also bans bare suppressions.
Lesson: a suppressed violation is a hidden defect. Fix at source or suppress per line with a stated reason.

SB5: datetime.UTC breaking py39 hooks (fixed 3+ times)

Symptom: hook import chains crash under host Python 3.9 because datetime.UTC is a 3.11+ alias. On PR #511 this was the sole failing check, with three cascade failures rooted in one ImportError.
Root cause: ruff's pyupgrade rule UP017 kept auto-rewriting timezone.utc back to datetime.UTC, silently re-breaking the fix. The linter was fighting the fix.
Evidence: 18c9340d (leyline quota_tracker, 2026-05-07), b0049fde (abstract), 709dafc9 (attune).
Status: settled by a durable guard, not by the fixes themselves: an AST-scanning test (plugins/leyline/tests/test_python39_compat.py) fails CI on any reintroduction, root ruff config extend-ignores UP017, and the surviving per-line pyupgrade suppression markers each carry a stated reason.
Lesson: when the linter fights the fix, only an AST invariant test holds the line. A fix commit alone will be reverted by tooling.

SB6: unguarded yaml/anthropic imports in hook chains

Symptom: every git commit emitted a PreToolUse hook ModuleNotFoundError.
Root cause: gauntlet's __init__ eagerly imported dependencies (yaml, anthropic) that the bare host interpreter running hooks does not have.
Evidence: 45dd77ef (guard yaml import, #518, 2026-05-08), 9bfc0a7a (defer anthropic import to function scope). Regression tests block re-imports with a sys.meta_path blocker (plugins/gauntlet/tests/unit/test_challenges.py).
Status: settled.
Lesson: hook entrypoints and everything they transitively import must be import-safe under a bare interpreter with no third-party packages.

SB7: herald LLM timeout exceeding the hook budget

Symptom: the herald double-shot-latte Stop-hook judge produced no verdict at all in the failure case.
Root cause: LLM_TIMEOUT_SECONDS = 30 inside a hook registered with a 10-second budget. The harness killed the whole hook before the LLM subprocess returned, so even the deterministic path's verdict was lost.
Evidence: 3d22f02a (the judge), 268cff89 (2026-05-30: cap LLM timeout to 8s, gate the LLM second shot to the single ambiguous outcome). A guard test asserts LLM_TIMEOUT_SECONDS is below the registered hook timeout (plugins/herald/tests/unit/test_double_shot_latte.py).
Status: settled.
Lesson: assert every subprocess timeout against the registered hook budget in a test. Deterministic tests do not exercise optional branches, so the optional branch needs its own guard.

SB8: silent scanner failures B1-B4

Symptom: quality scanners silently dropped files on malformed input, so broken inputs produced clean-looking reports. One metric reported Elite on malformed tags.
Root cause: except-and-continue blocks in scanner loops swallowed parse errors.
Evidence: 666171c3 (2026-06-18, fixes #575, findings B1-B4 from PR #521), b6de71cf (plugin-check: bound hangs, unmask failures).
Status: settled. Scanners now emit ADVISORY findings instead of skipping silently.
Lesson: except-continue in a scanner is a landmine. A scanner that cannot parse an input must say so in its output.

SB9: hooks reading env vars Claude Code never sets

Symptom: the [Learning] discussion digest went quiet after 2026-04-25. That starvation was the only visible symptom.
Root cause: PreToolUse/PostToolUse hooks (skill_execution_logger, pre_skill_execution, homeostatic_monitor in abstract, leyline noqa_guard, sanctum deferred_item_watcher) read CLAUDE_TOOL_* environment variables that Claude Code never populates. The payload arrives as JSON on stdin. The hooks exited 0 without doing anything, for months.
Evidence: CHANGELOG 1.9.14 (2026-06-27). Fix: canonical stdin-first reader read_hook_payload in plugins/abstract/hooks/shared/hook_io.py, with env-var fallback for the test harness. Consumers: the five hooks above.
Status: settled.
Lesson: a hook that exits 0 is not a hook that worked. Verify hooks actually fire and consume the real payload contract (stdin JSON).

SB10: neutered mypy gate

Symptom: typecheck was green while real type errors accumulated.
Root cause: the global mirrors-mypy pre-commit hook silently disabled 13 error codes, and the typecheck hook ran --changed instead of --all.
Evidence: CHANGELOG 1.9.12 (2026-06-18): neutered hook removed, per-plugin strict mypy with --all, new typecheck.yml workflow gating every PR.
Status: settled.
Lesson: a green gate that disables checks is worse than no gate. Audit what a gate actually runs, not whether it passes.

SB11: CI pin breakage (recurring)

Symptom: CI failures from tool pins that were never valid or aged out.
Root cause: setup-uv@v8 bare tag does not exist upstream, and bandit newer than 1.8.6 dropped Python 3.9 support needed by hooks.
Evidence: f81d89a5 (pin setup-uv to v8.2.0), 25bf5a9d (pin bandit 1.8.6).
Status: settled by standing guards scripts/check_pinned_versions.py and scripts/check_ruff_version.py (pre-commit, run only when the relevant files are staged).
Lesson: pin exact tags and let the guard scripts flag drift. Never trust a major-version alias tag to exist.

SB12: gh discussion CLI does not exist

Symptom: playbooks called gh discussion create/comment/list and failed. There is no such gh subcommand.
Root cause: hallucinated CLI surface. GitHub Discussions are reachable only through the GraphQL API.
Evidence: CHANGELOG (minister playbook repair replaced the calls with GraphQL mutations). Working templates live in plugins/leyline/skills/git-platform/modules/command-mapping.md using gh api graphql.
Status: settled.
Lesson: Discussions equal GraphQL only. Any script touching Discussions goes through gh api graphql, never a gh discussion subcommand.

SB13: pensive break halted multi-hit overflow detection

Symptom: pensive's integer-overflow scan reported at most one hit per file (PEN-013).
Root cause: a loop break after the first finding.
Evidence: 4993273b (2026-06-22).
Status: settled.
Lesson: in detection loops, collect all findings. An early exit in a scanner is a correctness bug, not an optimization.

SB14: broken relative paths from the plugin cache directory

Symptom: conserve's session-start hook failed when the plugin ran from the Claude Code cache directory instead of the repo checkout.
Root cause: a relative path assumed the repo layout. Installed plugins execute from a cache dir where sibling repo paths do not exist.
Evidence: CHANGELOG ("Inlined JSON utilities in conserve session-start hook"), later generalized in a8c9e4e9 (vendor json_utils.sh per plugin).
Status: settled.
Lesson: plugins run from a cache dir. No relative paths out of the plugin root, ever. Vendor small utilities per plugin (see SB1: this duplication is intentional).

SB15: imbue body-text fallback over-classification

Symptom: imbue classified unrelated skills as review-workflow because a fallback matched loose body text when frontmatter did not answer.
Root cause: a defensive fallback standing in for data that should be authoritative. The fallback masked the real signal instead of failing loudly.
Evidence: 69fbd32c (2026-06-24, remove the fallback). Pattern codified in .claude/rules/prefer-invariants-over-fallbacks.md (9f771794) and the imbue verifier-integrity module (29081fda).
Status: settled.
Lesson: a fall

missing capabilities entries), `d6c128f5` and `01a13e70` (further

`backup/unbloat-20260328`.

- Root cause: ruff's pyupgrade rule UP017 kept auto-rewriting
`timezone.utc` back to `datetime.UTC`, silently re-breaking the fix.
The linter was fighting the fix.
- Evidence: `18c9340d` (leyline quota_tracker, 2026-05-07),
`b0049fde` (abstract), `709dafc9` (attune).
- Status: settled by a durable guard, not by the fixes themselves:

### SB6: unguarded yaml/anthropic imports in hook chains

- Symptom: every `git commit` emitted a PreToolUse hook
ModuleNotFoundError.
- Root cause: gauntlet's `__init__` eagerly imported dependencies

### SB7: herald LLM timeout exceeding the hook budget

- Symptom: the herald double-shot-latte Stop-hook judge produced no
verdict at all in the failure case.
- Root cause: `LLM_TIMEOUT_SECONDS = 30` inside a hook registered with
a 10-second budget. The harness killed the whole hook before the LLM
subprocess returned, so even the deterministic path's verdict was
lost.
- Evidence: `3d22f02a` (the judge), `268cff89` (2026-05-30: cap LLM

outcome). A guard test asserts `LLM_TIMEOUT_SECONDS` is below the
registered hook timeout
(`plugins/herald/tests/unit/test_double_shot_latte.py`).

### SB8: silent scanner failures B1-B4

- Root cause: PreToolUse/PostToolUse hooks (`skill_execution_logger`,
`pre_skill_execution`, `homeostatic_monitor` in abstract, leyline
`noqa_guard`, sanctum `deferred_item_watcher`) read `CLAUDE_TOOL_*`
environment variables that Claude Code never populates. The payload
arrives as JSON on stdin. The hooks exited 0 without doing anything,
for months.
- Evidence: CHANGELOG 1.9.14 (2026-06-27). Fix: canonical stdin-first
reader `read_hook_payload` in

### SB10: neutered mypy gate

- Symptom: typecheck was green while real type errors accumulated.
- Root cause: the global mirrors-mypy pre-commit hook silently
disabled 13 error codes, and the typecheck hook ran `--changed`
instead of `--all`.
- Evidence: CHANGELOG 1.9.12 (2026-06-18): neutered hook removed,
per-plugin strict mypy with `--all`, new `typecheck.yml` workflow
gating every PR.
- Status: settled.
- Lesson: a green gate that disables checks is worse than no gate.
Audit what a gate actually runs, not whether it passes.

### SB11: CI pin breakage (recurring)

- Symptom: CI failures from tool pins that were never valid or aged
